EDITORIAL JULY 2014
Through a Lens Brightly— Vision Systems Take on Industrial Tasks and Look to the Future Robotic vision systems are sexy. We see videos of dual-camera mobile robots navigating over dirt paths through the woods. Advances are being made in automotive systems from collision detection to that “Holy Grail” sometimes referred to as that “giant hype,” of the driverless vehicle. Advances in machine vision systems go on at an impressive rate with object detection and recognition growing in power and sophistication. At the high end, this involves teaching a system using supercomputer scale neural networks for the learning process and then transferring that knowledge to a smaller scale embedded or mobile system. For example, this has recently lead to a vehicle vision system that can be housed in a small box in the trunk of a car—truly a major step toward that autonomous vehicle. What may be attracting less attention is the growing use of vision systems in a whole range of dedicated industrial applications where they are taking over seemingly routine tasks but saving large amounts of time, effort and money in the process. Such systems certainly qualify as robotic applications but are focused on more specialized tasks such as parts and/or wafer inspection or traffic management where they may be employed to count the cars waiting at a light to optimize the waiting times between light and heavily traveled streets. They are used in machining and in a growing number of operations in manufacturing where images are processed to guide machinery. This is frequently done by “teaching” the system with an image of the work piece. Consider, for example, a piece of metal that is to have holes drilled in it. Rather than set up a precision jig with sensors and positioners with an automatic feed to exactly position the work piece so that the pre-programmed drilling equipment can hit the exact spot, an image can be used to guide the equipment. Using the taught example with the exact locations defined, it can be compared to the image of the target piece and the drill moved exactly to the right spot on the target without the target being in the exact desired position. It just needs to be close and held firmly in place. This little example pays off big time when it is necessary to machine a different piece. There is no need to redesign a new positioning system with its clamps, sensors and reprogramming. It is only necessary to reprogram the vision system with a new sample pattern, image

acquisition and processing code, and to reprogram the control loop. In other words, it can mostly be done in software. In many cases, it may be advantageous to have a human operator place and secure the work piece in place and then let the vision guided system do the work. In order to be considered machine vision, as opposed to an image capture, processing, analysis or display system, it is at least implied that it has to do something. In many industrial applications that can be referred to as vision directed motion or vision servoing. So a system must bring together three basic components: image capture to acquire the visual data upon which to base the system’s function, image processing to extract and/or apply the relevant data and information needed for the system’s goals, and a control loop to carry out the actual function. Of course, the “something” it is expected to do can be simple or complex and as such will determine the demands put on the first two elements. While many vision systems are built using special processors, DSPs, ASICs and the like, it is increasingly possible and practical to implement a powerful system on a multicore-based PC with, or sometimes without, certain other hardware such as a frame grabber card. Newer camera interfaces such as GigE Vision and USB3 Vision can input image data directly without the need for a frame grabber. In addition, there are options available for Smart cameras that can preprocess image data to assist the PC-based system if need be. Of course, such cameras are costly and it is becoming easier and more economical to let the system software handle the image capture and processing. And, as we all know, cameras are becoming ever smaller and less expensive even as their resolution and capabilities increase. That can lead to an ever brighter future for machine vision in what may become everyday applications. The cost reductions and capabilities now realized in industrial PC-based systems will only improve, while smaller form factors will bring vision-based apps into more mobile and embedded devices. They could be stand-alone apps with limited or focused capabilities or, if developed in conjunction with large learning systems, could become very advanced but handheld object and facial recognition systems with wide possibilities for as-yet unforeseen applications.

Biomedical Big Data Now Able to Process a Complete Human DNA in Less Than 30 Minutes
At the European Society of Human Genetics conference in Milan, Genalice announced the scheduled release of an upgraded version of its Next-Generation Sequencing (NGS) DNA data processing software solution Genalice Map. Featuring the new 5-minute variant caller, the company is now capable of processing the DNA data of an entire human genome with 40x depth within 30 minutes on a commodity dual Intel Xeon E5 server. The company commercializes its software in a turnkey appliance, the Genalice Vault. This all-in-one bioinformatics tool is preloaded with the company’s breakthrough DNA processing solution Genalice Map. Hans Karten, CEO/CTO, explains: “The two key processing steps after DNA has been sequenced are short read alignment and variant calling. In our first release we only included the alignment part. We are extremely pleased to upgrade our software suite with our ultra-fast and highly accurate variant caller. Both steps normally take 1 to 2 days on a similar hardware configuration. By mastering both steps in less than 30 minutes now, we have created a processing pipeline that offers our customers spectacular benefits. Exome data or panels can be processed in near real time. Combining our speed and footprint reduction, we are able to drive down the cost of processing and storing a full genome to less than $100 per year, while further improving the quality.” The company has collaborated with several scientific institutes to
validate their pipeline. In the public domain Genalice tested its product with well-known reference datasets like “Genome in a Bottle,” and has used the highly recommended Genome Comparison & Analytic Testing (GCAT) tool from Bioplanet. com to directly compare the sensitivity and specificity with most commonly used conventional tools. The results have been drafted in a white paper and GCAT report. Both can be found at the company’s website in the product section under Genalice Map.

hat do the following things have in common: selfdriving car technology, video streaming of World Cup soccer/football, global warming sensor measurements, UAV photo capturing and remote household appliance control? Hint—it’s not a government surveillance program involving metadata collection. Okay, at least that’s not the answer we were looking for. The Internet of Things (IoT) has given renewed enthusiasm to developers and lucrative valuations to Wall Street, as well as a fresh facelift to aging computer board alliance programs. Although vast database-driven Web pages are full of new and nearEOL boards alike, the latest certification programs create real value to OEMs by bringing together fully tested hardware and software. It’s not a new idea for every device and gadget under the sun to have its own unique address. It has taken ten, even twenty years for early concepts to finally take hold on the massive scale that is now underway. Previous obstacles like size and power reduction are being overcome at an unprecedented pace. Where does desktop PC technology fit into the IoT realm? Small form factor (SFF) computer boards are already widely used in mobile and line powered embedded systems. Yes, “embedded.” The term has not actually reached obsolescence in this IoT era. The “15 billion embedded devices by 2020” target has been simply re-labeled as “30 billion devices on the IoT by 2020.” Or perhaps re-focused. After all, these are not all Frenchstyle smart cards and cell phones. There are quite a large number of tiny systems with unique requirements that cannot be met with a one-CPU-fits-all approach. Nor a single Internet gateway. Nor a single wireless (radio) interface. When all you have is a hammer, everything looks like a nail. SFF x86 board and chip vendors apply 64-bit multicore processors with huge caches and fast interfaces like PCI Express, SATA, USB and Wi-Fi to the myriad of tiny micro-power sensors and mesh networks. Even if each processor core only draws 2 watts when lightly loaded, the I/O and memory interfaces burn much more power than necessary to accomplish edge tasks. WiFi is not the best fit for a large number of endpoints that hardly

need to update more than a few times a second, if even that. Working backward from the endpoint perspective, one can calculate the bandwidth each device needs in both directions. Often in the broader IoT picture, sensors sip from a faucet. By comparison, edge routers and access points drink from a fat pipe while core routers and Big Data servers and Cloud storage devices gulp from a fire hose. Serial ports, SPI bus and I2C are examples of interfaces that not only match the data rates, but are also easy to attach to using a CPLD or small FPGA, or even bitbanging with GPIOs that microcontrollers have. In many cases, microcontrollers and 32-bit ARM SoCs have built-in UARTs, USARTs and SPI ports that run faster, with FIFOs that don’t tie up the micro. Some low-cost, low-power A-to-D chips have direct SPI interfaces, obviating the need for an FPGA at all. Similarly, an onboard SSD chip or flash in the microcontroller itself is more optimized than mSATA, M.2 or m-anything else. The x86 processor community killed off serial ports when USB took over desktop peripherals. Fortunately, the embedded market does have influence at the lowest end of modern x86 SoCs, where serial ports have re-emerged. It’s usually applications like car computers that have the unit volumes to buy influence. Don’t get your hopes up too much when you see the SPI port on the datasheet or pinout, because that is usually reserved for firmware. So the IoT isn’t going to become the IoC (Computers) any time soon, despite all best efforts. You have to Sprechen Sie I/O first. Then a well-tested small Linux or RTOS, or no OS is important to the dialog. There’s no getting around it, though. PC technology has become quite embedded into the everyday life of the developer community. Even though they are comparatively large, bulky and costly, such off-the-shelf building blocks are convenient in a world where time-to-market translates into market share. Even if not cost-optimized, x86 systems will ride the wave rather than miss the boat, clear out to the access points and even in some edge systems where data crunching is more efficient to do there. Where there’s an I/O bridge and accompanying device driver, there’s a way. But the lowest power edge devices with IP interfaces will be captured by ARM’s iron hand.

EDITOR’S REPORT Advanced Electronics for Solar Panel Conversion
Solar Power Opening up Advances for Control and Conversion Modules The dropping price of photovoltaic solar panels along with the development of improved ways to extract their optimal power is opening up a world of opportunities for embedded electronics as the control moves closer to the panel. by Tom Williams, Editor-in-Chief
Centralized Solar Inverter
JULY 2014 RTC MAGAZINE
String PV Arrays
The rather simple reason is that while solar panels convert sunlight into energy and present a voltage at their terminals, is doesn’t end there. The power produced by
here are increasingly clear indications that we may soon be looking at a surge in renewable energy, particularly in solar power. Interestingly, this does not appear to be happening as a result of government regulation such as the recent carbon limits announced by the EPA. Rather, it seems to be a result of cold, hard numbers representing the costs of solar vs. those of coal-fired plants, with solar poised to drop below the price of coal. In fact, Barclay’s Bank recently downgraded the bonds of several utilities based on their continued use of coal. Germany is already setting an example with a huge expansion of solar energy as well as wind power. The expansion of solar photovoltaic energy could have huge implications for the semiconductor industry as well as for the developers of embedded controllers and the build-out of the Smart Grid.
the panels must be controlled, combined with the output of other panels and converted into AC power that can be used to run homes, offices and facilities, placed on the grid and/or stored for later use. There are relentless efforts underway to improve the efficiency of solar panels themselves to produce more power per surface area. There are also intense efforts to improve the efficiency of the control and conversion systems that ultimately deliver the power to the user. Basically, that involves taking the DC output of the panel, converting it to a target DC voltage and then sending it to an inverter to produce AC. One of the main reasons for the DC/ DC conversion is that the output voltage varies among panels so that it is necessary to get a single common DC voltage to feed into the inverter. One of the earlier and most common approaches has been to connect groups of panels serially in several “strings” using special diodes (which cause losses) to allow for the different string voltages and simply feed them into a single large inverter. This had been the traditional approach taken by large arrays at solar farms and utility plants. The DC from the strings must still be converted to a fixed DC in the inverter before being converted to AC. This is not really optimal because it is converting the output of all the panels and some panels may not be delivering the peak power they may be capable of (Figure 1). The trend for controller/inverters is moving toward implementing them on
FIGURE 1 The “traditional” central topology for a solar array involves feeding the output of several strings into a single, often large, central converter that converts the panel outputs to a single DC voltage that is then fed into a DC/AC inverter (Courtesy Texas Instruments).
smaller groups of panels within an array, and further toward implementing them on each individual panel. One variation on the above approach it to do DC/DC conversion at each panel using microconverters while connecting the panels in parallel and feeding their output into a central DC/AC inverter. This increases efficiency somewhat but still involves a single large inverter, which may be fine for a central utility plant but is less attractive for systems placed on residential rooftops or commercial buildings.
Upending the System
This last little item, which we can collectively refer to as “rooftop solar,” is inherently a disruptive technology. Taking power generation out of a centralized location with its distribution and billing systems and dispersing it at user locations has the potential to radically change the assumptions long associated with local monopolies (regulated though they may be) like utility companies. While relatively few users are likely to be completely off grid, the vast majority will increasingly have the opportunity to use rooftop solar to supplement the power they take from the grid by having systems that push surplus power onto the grid and remove only what they need when they need it. Another potential alternative is to add local storage
to such a system so that very little if any interaction with the grid will be needed. With the cost of solar installations falling about 10% per year, we can look for some pretty rapid acceleration that will not be significantly affected by added fees and/or political resistance. Nor will it be significantly accelerated by government regulation. Market economics can be expected to act as the main driver. Texas Instruments has produced a number of solar development kits to help engineers design and evaluate controllers, converters and inverters for solar power applications. The most recent such kit, based around TI’s C2000 Piccolo TMS320F28035 microcontroller, supports the most recent and advanced approach to solar panel power conversion and control, the micro-inverter (Figure 2). It also appears to indicate TI’s recognition of the extremely high market potential for solar inverter technology and the semiconductor products that will support it. The micro-inverter is used at the output of each individual panel and integrates DC/DC conversion along with DC/AC inversion plus some control and optimization functions to be described later. According to TI MCU application engineer Manish Bbhardwaj, the most frequently used approach for rooftop solar until recently has been the string topology in

which 10 to 12 panels are connected in serial and then handled by one converter/ inverter. Several such strings can then be connected in parallel. Now, however, the trend is moving toward the micro-inverter, which performs DC/DC conversion and DC/AC inversion at each panel (Figure 3). There are several immediate advantages for residential users and the companies that install rooftop systems. First, if one panel in the array is shaded or damaged, it does not affect the output of the other panels in the array. Second, the system is easy to expand. Simply adding one or more panels with their own micro-inverters adds power to the systems without

having to worry about upgrading a central converter to handle the additional current. While micro-inverters are used for grid-tie systems in which power is put on and taken off the grid as needed, the micro-inverter is not involved in the “bookkeeping.” The ultimate charge or credit from the electric utility is handled by the smart meters that are rapidly replacing the old-style electric meters that required a human meter reader. Smart meters, in conjunction with wireless and power line communications, are in many locations already capable of handling grid-tie solar panel systems.

As noted earlier, the actual output of which a solar panel is capable can vary according to such things as temperature, partial shading or even damage. Their maximum output also varies according to time of day. It is obviously important, therefore, to be able to extract the maxi-
mum power available from each panel throughout these changing conditions where that maximum obtainable power will vary. The micro-inverter’s internal controller has two main responsibilities. First, in doing the DC/AC conversion, it also must lock the AC output to the frequency of the grid. Second, it must see to it that the panel produces its maximum available power from moment to moment via a process called maximum peak power tracking (MPPT). The real-time processors—in this case, the TI C2000 series—use A/D converters for input and pulse width modulators (PWMs) for output to adjust the DC/ DC converter and the DC/AC inverter by changing the PWM duty cycle according to the load. Thus the DC/DC conversion happens at the optimal power output. The AC output voltage is the same as that of all the other panels, but each panel then delivers the maximum power of which it is capable in a process that is continuously
updated. Two things appear to be converging: the dropping price of solar panels along with their constantly improving efficiency, and the advancing capabilities of the electronic components and modules that can produce optimal useable electrical power in a vastly distributed world of grid-tied systems, systems with increasing storage capabilities, and a growing but much smaller number of off-grid systems. The opportunities for even more improved control and conversion technologies do indeed seem bright. Texas Instruments Dallas, TX (972) 995-2011 www.ti.com

Java Links the Field to the Cloud
Use Java to Develop Complex M2M Systems That Deliver Data to the Enterprise M2M projects present many challenges, even when the hardware is designed exactly to customer specifications. Success can be best assured with effective implementation of the device logic, scalable methods for device and data management, and simple integration of distributed devices into different enterprise applications. by Robert Andres, Eurotech
usinesses need â€œoff-the-shelfâ€? purpose-built solutions to address interoperability and seamlessly connect, aggregate, filter and share data from the edge of the network to the Cloud. The emergence of a Multi-Service Gateway model, which operates on the edge of an M2M deployment as an aggregator and controller, has opened up new possibilities. IT-centric solutions based on Java can be used to develop a very sophisticated, managed and robust network-connected application in a very short amount of time, with minimal effort and without compromising quality. Eurotech recently introduced a complex environmental monitoring system with Oracle at Embedded World, the ReliaSENS 18-12, which demonstrates how the right technical building blocks including multi-service gateway hardware combined with standards-based software components can lead to a rugged, reliable M2M system. The use of such technical building blocks can leverage Java to ensure shorter development times, more deterministic development and future-proof M2M applications.

FIGURE 1 Multi-Service Gateways consolidate multiple business-relevant tasks into an overall application framework.
Simplifying Environmental Monitoring with a Multi-Service Gateway
Because many M2M edge devices are complex, an environmental monitoring system provides an excellent example
where various sensors and devices must be combined to create a cohesive system. Consider a Cloud-connected environmental monitoring system with high-precision air pollution sensors and real-time data access. The system must be rugged and

compact to withstand the elements, and will be designed to monitor traffic, industrial, construction and urban areas for temperature, gaseous pollutants, particulates, electromagnetic fields, radioactivity and sound pollution. Furthermore, it will be built to seamlessly connect to the Cloud and send data from the field to the business application in real time. The M2M marketplace is full of hundreds of piecemeal technologies that can be cobbled together to form a solution, but complex devices like an environmental monitoring system are best developed using the Multi-Service Gateway approach (Figure 1). The Multi-Service Gateway approach minimizes development risk by using off-the-shelf, purpose-built systems and boards designed to meet vertical market value propositions. These hardware elements come with an integrated powerful M2M/IoT software stack that allows the development of the devices business logic in Java. These systems or boards are therefore also suitable platforms to build more complex systems by adding sensors and actuators to create powerful appli-
ances like an environmental monitoring system (Figure 2).
Java-Based Application Framework
The Multi-Service Gateway approach solves a number of integration problems and unifies disparate components in the environmental monitoring system. One fundamental building block is an application framework to put a layer between the operating system and the business application on the gateway. Through the Everyware Software Framework (ESF), Eurotech provides a set of common services for Java developers building M2M applications, including I/O access, data services, network configuration and remote management. Eurotech assures a strong foundation for M2M applications by relying on leading industry partners (Oracle’s Java Embedded Technologies, Hitachi SuperJ OSGi platform) to provide the technology basis for device, network and service abstraction as well as efficient development. The OSGi framework is a module system and service platform for the Java programming
language that implements a complete and dynamic component model, something that does not exist in standalone Java/VM environments. The benefits of IT-centric application development using ESF (Figure 3) to implement business logic in smart edge devices / service gateways include simplifying application development for smart M2M Multi-Service Gateways and smart edge devices as well as optimizing portability across systems and hardware architectures. It greatly improves local and remote management of both devices and applications and enables native M2M platform integration by means of Everyware Cloud and Message Queuing Telemetry Transport (MQTT). Oracle Java Embedded is beneficial for application code development in connected devices such as the environmental monitoring system because it provides a robust software infrastructure for service delivery platforms. This enables easy code development through software simulation before porting onto the embedded devices thus reducing time-to-market. Using an OSGi-based container on top of a Java Virtual Machine simplifies application development and optimizes portability across systems and hardware architectures should the need arise in the future. ESF is a general-purpose, secure and managed framework that leverages OSGi and supports the deployment of extensible and downloadable applications known as “bundles.” Bundles can be downloaded, installed, started, stopped, monitored and uninstalled on the fly, even while other applications are running. Hitachi’s SuperJ Applications Ecosystem is a framework for the OSGi Service Platform that facilitates the modularization of software components and applications and assures interoperability of applications and services over a variety of M2M devices. SuperJ offers additional benefits such as the ability to deploy multiple versions of a module concurrently on a Multi-Service Gateway. ESF offers many additional elements including simple means to support field protocols, GPS services, administration GUI, customer business logic and a Cloud client. ESF can enable all of this functionality by encapsulating the complexity of RTC MAGAZINE RTC MAGAZINE OCTOBER JULY 2013 2014
the lower layers and creating a foundation layer upon which customers can build their application and start with their value add from day one. An advanced software framework that leverages OSGi and Java isolates the developer from the complexity of the hardware, and the networking subsystems brings the Multi-Service Gateway hardware into an integrated hardware and software solution (Figure 4). Building on proven architecture and software building blocks that would require many years to develop, the use of an M2M application framework will result in shorter, more deterministic device software development. Using this IT-centric approach to implement the device logic in smart edge devices such as the environmental monitors improves both device management and application management. Once this standard software platform is in place, connecting to the Cloud is simpler than it ever has been before.
OSGi-Based Application Framework for M2M Service Gateways
The Eclipse Kura project is an effort aimed at offering a Java/OSGi-based container for M2M applications running in Multi-Service Gateways. Kura provides or aggregates open source implementations for the most common services needed by M2M applications. Kura components are designed as configurable OSGi Declarative Services exposing the service API and raising events. The initial contribution of the Kura project will be a large subset of the current Eurotech Everyware Software Framework. The goals of the Eclipse Kura project can be summarized as: • Provide an OSGi-based container for M2M applications running in service gateways. Kura complements the Java 6 SE and OSGi platforms with API and services covering the most common requirements of M2M applications. These extensions include but are not limited to: I/O access, data services, watchdog, network configuration and remote management.
OCTOBER JULY 20142013 RTC MAGAZINE RTC MAGAZINE
FIGURE 3 ESF developer experience: designed from the ground up for developers.
• Kura adopts existing javax.* API for its functionalities when available—for example javax.comm, javax.usb, and javax.bluetooth. When possible, Kura will select an open source implementation of such API that is compatible with the Eclipse license and package it in an OSGi bundle to include it in the Kura default build. • Design a build environment, which isolates the native code components and makes it simple to add ports of these components for new platforms in the Kura build and distribution. • Provide a development environment that allows developers to run M2M applications in an emulated environment within the Eclipse IDE, then deploy them on a target gateway, and finally remotely provision the applications to Kura-enabled devices on the field. Kura offers a foundation on top of which other contributions for field bus protocols and sensor integration can reside.
M2M Integration Platform
An M2M integration platform designed to act as an intermediary system between the distributed devices and the applications making use of the data, can further reconcile the varied technologies found in complex M2M projects and help customers to quickly connect their devices in the field to the business applications on the enterprise IT side. An effective M2M integration platform must act as an operating system for the IoT, enabling the transfer of device data independent of any programming language, platform, or underlying technology. An M2M platform is essential in the environmental monitoring system, with a large number of devices in the field collecting data and connecting to a backend system with multiple user applications such as a desktop GUI, handheld device applications and server data storage. Clients have the choice to build out their own backend server system and associated software elements, or look to a Cloud-based system where much of the solution has been provided. Which solution is best depends on many factors in-
cluding: core competencies, complexity, capital investment, time-to-market requirements and more. The Multi-Service Gateway approach aided by a 100 percent Java application framework can ensure successful and deterministic development and deployment of M2M solutions for a broad range of vertical markets. A well designed M2M/IoT architecture and proven building blocks, including an enabling device middleware—a Java and OSGi-based application framework—allows customers to focus on their core competencies and provide higher value through services, improve efficiency, and reduce costs while developing, deploying and maintaining the connected devices in the field.

Java Links the Field to the Cloud
Embedded Systems and the Internet of Things—What’s Under the Hood? As the Internet of Things continues to grow, it is changing the nature of the devices that are attached and how we interact with them and their data into an object-oriented paradigm. This opens a path for a software system like embedded Java to be a natural means of development, control and interaction. by Tom Angelucci, Oracle
hange is afoot in the world of embedded systems. As the Internet of Things (IoT) creeps closer to the precipice of delivering the scale of machine-to-machine (M2M) communication that’s long been promised, so, too, are new ways of doing things starting to displace tried-and-true tools and strategies. Nowhere is this more evident than on the platform front. Having dominated embedded system design for decades, stalwart languages C and Assembly have been rapidly ceding market share to modern, object-oriented alternatives, most notably Java. There are numerous reasons for this shift, from the ramped-up timeto-market pressures enterprises face to the “write once, run anywhere” portability Java Embedded affords. The bottom line is that Java Embedded appears to be staking its claim as the preferred programming language businesses use to develop IoT applications. Java is “the language of choice within the enterprise, and what will drive M2M is not only the engineering community, but also businesses embracing it,” Michael Azoff, principal analyst at research firm Ovum, wrote in a recent report.

And what businesses need right now is the ability to make quicker, better and smarter decisions with the IoTs’ fountain of data. So, when a motion sensor at the entrance to a building detects a breakin, it shouldn’t merely turn on the alarm system; it should also automatically start

location of a repair team who can more quickly and efficiently address the problem and then effect repairs. Engineering teams are, of course, eager to satisfy business demands. So it’s no surprise that survey findings from VDC Research indicate that the portion of embedded systems design projects powered by Java rose from 12.3 percent in 2008 to 27.8 percent in 2013. Meanwhile, use of C during the same period dropped from 91.6 percent to 59.8 percent, and use of Assembly fell from 47.4 percent to 19.1 percent. With billions of devices expected to join the IoT over the next several years, analysts expect organizations to continue this migration away from the legacy static languages that have been traditionally used. This steady integration into the IoT will have significant impact on device design (Figure 1). “The Internet of Things is rendering many incumbent embedded engineering technologies and design processes insufficient and antiquated,” Chris Rommel, vice president of M2M and embedded technology at VDC, wrote in a research report accompanying the firm’s survey findings. “Engineering organizations now need new solutions that address these evolving
requirements and speed development and time to revenue.” It is only set to get worse—or better, depending on one’s perspective. A recent survey of 1,867 Internet experts and stakeholders conducted by the Pew Research Internet Project found that there’s no perceived limit to where the IoT will show up in the near future. Respondents predicted that the IoT will be evident in most goods and services, ubiquitous in our homes, communities and environments, and will even be making appearances in our bodies. The research survey noted commentary from Patrick Tucker, author of “The Naked Future: What Happens in a World That Anticipates Your Every Move?,” offering a succinct written analysis of where he sees the IoT heading: “Here are the easy facts: In 2008, the number of Internet-connected devices first outnumbered the human population, and they have been growing far faster than we have,” wrote Tucker. As the array of predictions in the Pew survey indicates, the range of devices that will make up IoT is likely to vary wildly in footprint and function. As such, developers can expect to see embedded system design projects pop up everywhere from assembly line machinery and building au-
tomation systems to pacemakers and even toothbrushes. Working with these devices is definitely a new and different domain for most application developers. And the changes that will come to the devices themselves as they are integrated into the IoT will call for ways to make their development more approachable (Figure 2). For starters, these devices are often “resource constrained.” They might have a smaller memory footprint, and they don’t have a human on the other end that can click on an option or push a button to upgrade. A lot of these devices will be field-deployed in some cases for 10 or 15 years without anyone ever touching them. They will, however, be producing huge volumes of sensor data, making independent decisions and integrating with enterprise systems (such as analytics databases), all needs for which Java Embedded is well suited. But Java Embedded delivers a number of other advantages as well. First, there’s the fact that Java’s runtime environment, the Java Virtual Machine, can run multiple applications simultaneously and securely without having one affect the other, enabling programming to be broken down into reusable modules. Right there,

we’re talking shorter development cycles and lower costs. That modularity, in turn, offers a significant security payoff by preventing malicious programs from affecting multiple applications, a critical layer of protection when embedded IoT systems are accessing firmware updates. Java Embedded also addresses the issue of these devices being deployed in-field for the long term by enabling on-the-fly application downloads and updates, remote operation—often in challenging environments, and the ability to add new capabilities without impacting the existing functions. This extends the lifetime, flexibility and value of embedded solutions by enabling application upgrades in the field, without compromising the integrity and security of the system. All this goes to create a chain of data and services that runs from the smallest connected device to the Cloud (Figure 3). There is also abundant evidence that Java speeds up embedded system design efforts, not to mention interoperability and portability. Where embedded systems built using C are generally device specific, the ability of Java Embedded to enable

code reuse in a variety of IoT settings can further cut development time and costs significantly by breaking down embedded system silos. In the past, people would choose the components that go into a device and then write all the software in native code, so there weren’t a lot of considerations about interoperability or reusability of the code for other similar applications. Java, with its “write once, run anywhere” capabilities, allows developers to get started more quickly and to reuse code across devices. Oracle Java Embedded also delivers important staffing and resource benefits. To start, with a population of 9 million and growing, the Java programming community is large, making it much simpler for companies to find the developers they need. What’s more, because Java is an established enterprise asset in most companies, Java programmers can apply their skills as readily to enterprise application and Cloud development efforts as they can to embedded IoT projects. Still, with the IoT in its relative infancy, there aren’t a lot of large-scale deployments that demonstrate the potential

The solution is designed to support leading-edge smart metering, as well as big data integration and power network automation, to improve energy efficiency and quality of service. V2COM’s smart grid uses Gemalto’s Cinterion M2M modules, along with Oracle Java Embedded, to securely transmit energy usage data over wireless networks into backend utility systems. Oracle’s device-to-data-center solution is intended to enable electricity providers to reduce energy losses and fraudulent incidents by improving remote monitoring and management of energy consumption, and speeding up response times when outages occur.

Flash Memory: Growing in Size and Speed
Enhancing Storage Efficiencies from Greater Understanding of SSD Application Classes Solid state storage, implemented with NAND flash, has grown in speed, capacity and reliability. Still, qualifying a given device for a particular embedded application requires careful consideration of a number of interrelated metrics. by Scott Phillips, Virtium
he simple dollar per gigabyte metric no longer applies in evaluating storage solutions now that embedded systems computing has migrated from desktops and laptops to mobile devices and cloud storage. Developers have started to use a more sophisticated review process based on their specific application and its related data-type usage model. NAND flash technology employed by SSDs has also freed developers from the physical and mechanical spinning platter limitations of hard drives. In turn, SSD manufacturers have capitalized on the technology’s inherent advantages to optimize their solutions based on the application at hand. With the SSD industry continuing to explode, manufacturers are looking for ways to competitively position their products through technology differentiation and application-specific branding. This has caused several application classes to emerge. These classes are referred to as client, enterprise, data center and embedded SSDs. For the most part, SSDs are made up of the same components: a controller (ASIC or FPGA), NAND flash

(other technologies are on the horizon but none are yet as commercially viable), and possibly DRAM. These components are either integrated into a solder-down mul-
tichip package or are combined with other passives and mounted onto a printed circuit board of some type. So what characteristics differentiate SSDs built for each application class? The common answer from most SSD industry professionals is to define how the product is built as opposed to what the product does. They typically get into deep discussions about MLC vs. SLC vs. TLC (and now vs. 3D), write amplification optimization, read disturb mitigation, voltage threshold shifting and myriad other “secret sauces.” In the end, do any of these parameters really matter to system developers? Probably not. What is most important is that SSDs address developers’ needs by meeting the objectives of the applications’ usage models. Developers are keenly focused on finding the right storage solutions that fit their budget and application specs. That is why it is important to highlight the key external metrics of client, enterprise, data center and industrial SSDs without being overly concerned with the underlying technology and how these metrics are accomplished.
TECHNOLOGY IN CONTEXT
SSD Application Usage Models
To fully understand the reasons behind the different SSD application classes, let’s look at an overview of the applications for which they are designed. There are many well-known use cases and metrics associated with client applications that include desktops, notebooks and now ultrabooks, tablets and smartphones. In these applications, SSDs are used for storing operating systems and user data that is generated or downloaded by a single person. Performance is largely subjective based on individual needs with the most desired features being instant-on and application response time. Client SSDs are typically optimized for read speed. Write speed doesn’t matter as much, and there is quite a bit of downtime associated with client applications. This downtime is enough for the SSD to take care of any background task, such as flash management, that will help it achieve higher performance, greater reliability or longer endurance. Enterprise class SSDs were originally developed to replace racks of shortstroked enterprise class hard drives. In recent years, SAS has become the interface of choice for storing higher-reliability, mission-critical enterprise data that dictated the development of enterprise class SSDs, which use the same interface. SAS, with its dual port modes, DIF and other data integrity enhancements, offers the benefit of higher reliability than SATA. However, the performance capabilities of SSDs, which quickly highlighted the traditional hard drive interfaces as a major bottleneck, so impacted the enterprise that even more performance was desired. Enter PCIe as the high-performance interface of choice for today’s most demanding enterprise applications. Today, enterprise SSDs fall into three basic categories as shown in Table 1. Data Center SSDs are designed as the main storage building block for application-specific servers and appliances. Driving this application class are multiple Internet search and social media sites. SSDs for the data center are generally 6 Gbit/s SATA SSDs in capacities of 120 Gbyte and higher. SATA is typically chosen because it is a well-known,
FIGURE 2 Virtium offers some of the storage industry’s longest product lifecycles, which help minimize costly and disruptive requalifications. Its second generation SLC-based StorFly PE class products are guaranteed to not cause a requal for at least four years.
straightforward interface that is highly compatible and generally the most costefficient compared to SAS and PCIe. It is no wonder then that the SSD companies that stand out are those that manufacture NAND flash. For purposes of this analysis; data center SSDs are positioned for a lower cost per gigabyte while maintaining adequate IOPS and low latencies, and generally feature read/write speeds around 500 Mbyte/s and IOPS in the 60K+ range. The utilization of SSDs in industrial and embedded systems comes into clear focus with their deployment mainly in equipment that supports the infrastructure. Examples of infrastructure applications include networking and communication industry routers, switches and base stations; enterprise network security and monitoring devices; medical and gaming equipment; factory automation systems and digital signage…and the list goes on. Compared to the well-known usage models for client and enterprise SSDs, infrastructure SSD applications are highly fragmented, making them more difficult to segment into a particular application class. As noted previously, client SSDs are employed for read use cases and enterprise SSDs are used to support writeintensive workloads. Infrastructure SSDs, on the other hand, need to support a wide
range of mixed function workloads. Two opposite examples are casino gaming and radio base station applications. Casino gaming SSDs might only be written to once and then be write protected, but are read from as games are played. Base station SSDs may need to be continuously written with cell phone traffic log information. Infrastructure equipment data patterns can range from 99% read/ 1% write to just the opposite and can encompass every scenario in between. Infrastructure applications are also considered mission-critical and must be designed for 24/7 operation—many times in harsh, extended temperature environments ranging from -40° to 85°C and higher. Embedded infrastructure-based SSDs are frequently characterized by smaller, lower power, lower capacity form factors such as Slim SATA, mSATA, CompactFlash or 10-pin eUSB whose applications typically require capacities less than 100 Gbyte—with a large number of Linux and real time OS-based systems requiring less than 4 Gbyte (Figure 1). A common belief among infrastructure system developers is that industrial SSDs need to be built with SLC NAND, making them considerably more “expen-

sive” than client SSDs. This is not necessarily true. While SLC is more expensive on a dollar per Gbyte basis, there are many applications where the lowest-cost 120 Gbyte client SSD is still more expensive than the “right” 8 Gbyte SLC infrastructure SSD on a dollar per unit basis. There are also numerous mission-critical scenarios where SLC-based SSDs are essential, so the expense is justified with greater endurance and reliability over a longer product lifecycle.
Embedded system developers are also concerned with the high cost of requalification. The reality today is that there may be three iterations of MLC for every one iteration of SLC, which necessitate a requal for every iteration. For high-capacity requirements, it may still be difficult to cost-justify using SLC, but as capacity needs decrease, the total cost of ownership (TCO) and performance arguments for SLC become more compelling (Figure 2).
Rules Are Not Always Followed After reviewing the diverse set of applications, it should be abundantly clear why SSD application classes are defined by usage model and their associated workload requirements rather than technology. These definitions provide a helpful set of guidelines in specifying SSDs. However, not all SSD suppliers follow these guidelines, and it is not mandatory to do so. At the moment, the JEDEC JC64.8 SSD committee defines application
Consists of the types of data, file sizes, whether that data is sequential or random, and the read and write requirements of the application.
Defines the assumed case temperature inside the host system, generally on the SSD case, at which the SSD is written and read. It also defines how often the SSD is used.
Defines the storage temperature and the length of time the SSD can be powered off while still keeping the data intact after the SSD has reached its endurance specification.
Data Retention Time
Is an important metric point for industrial SSDs. If the SSD has barely been written, the retention time is significantly longer than an SSD that has been in use for a long time.
Functional Failure Requirement
Outlines the number of “acceptable” failures for a given sample size subject to specifically defined conditions.
Measures the number of sectors that return an uncorrectable bit error based on the number of bits that have been read.

classes only for client and enterprise SSDs in document JESD218. The workloads associated with these application classes are explained in JESD219. Unfortunately, embedded system developers may not find a given SSD specification to be particularly useful or meaningful if it isn’t based on a set of common rules. JEDEC definitions are helpful in specifying client and enterprise SSDs, but they don’t cover all of the considerations for embedded SSDs. Therefore, it is important for designers to carefully review datasheets to fully understand the assumptions and conditions under which the products are specified (Figure 3). Validating endurance for an infrastructure application class workload is an excellent example where designers may need to define many elements that include active use (power on) time and temperature, retention use (power off) time and temperature, and functional failure and uncorrectable bit error rate requirements. Adding to the challenge is that the metrics shown in Table 2 are all interrelated when it comes to endurance, and changes in assumptions for one parameter can lead to changes in another. This endurance example highlights the critical nature of understanding the use case for which an SSD is specified for its applicability and effectiveness in certain situations. Consequently, if SSD specifications do not provide use case data, they are truly of limited benefit to developers and should be questioned.
As the analysis should have highlighted, total cost of ownership and improved storage efficiency benefits can be achieved in embedded system designs by taking the time to fully understand SSD application classes. This information can greatly assist OEMs in selecting the most optimal solution for their particular design. Although it can be challenging to find the right SSD to meet budget and application specifications, there are expert storage suppliers ready to take a larger role in serving the needs of this diverse market with extensive expertise in guiding OEMs to the optimal storage solution, and by delivering high-reliability, quality products that are proven to work over the course of the systems’ lifecycle goals.

TECHNOLOGY DEVELOPMENT Fleet Management Systems
Taking Data Networks on the Road With the increasing demand for data to control and monitor today’s transportation systems and to fit into small spaces and rugged environments, the modular box PC is an attractive choice for in-vehicle systems. In addition, its flexibility lets it take on a wide range of different, demanding tasks. by Barbara Schmitz, MEN Mikro Elektronik
ith as much talk as there is about the Internet of Things, and how much can be done in the digital world, there is still an element to realworld operations that requires physically moving things from point A to point B. You can’t send a freight load of imported automobiles from our nation’s ports to car dealerships via Ethernet…yet. But the Internet of Things is still helping to move things along in this physical world, requiring a shift in thinking about how powerful data networks are making their way into industries traditionally considered “lower tech,” such as transportation, construction and agriculture. Who would have thought that an 18-wheeler, an underground mining machine, or a commuter train would be part of an interconnected global network? Historically, these industries have not used much technology, but they are under the same cost scrutiny and time-to-market

constraints as any other business entity looking to optimize operational efficiency within a set budget.
The Road to Efficiency
Businesses that employ a mobile workforce are tasked with a unique situation—most of the fleet operators are working remotely as well as independently with external, uncontrollable factors, such as traffic and weather that impact productivity. There is an inherent lack of control and oversight from the headquarters, so in the past managing certain operational parameters has been challenging. But once embedded technologies began shrinking enough to be used on vehicles, and then became smart enough to be connected remotely via wireless methods, an evolution began. Businesses realized that through proper fleet management, certain aspects of their business could be optimized, whereas previously the main
office staff had no connection to what was happening on the road. Three key areas where embedded computing is lending a hand include revenue generation through operational efficiencies and reducing risks by way of better on-road management of vehicle repair and fuel costs. In addition, it makes for increased communication resulting in better transparency with third parties, such as passengers, customers or other vehicles on the road. Not only do today’s fleet management operations connect a driver with the main office, but vehicles can communicate with one another, with back-end computing systems and with other agencies or systems, depending on the nature of information being communicated. Modern commercial vehicles, like buses, coaches and trucks as well as offhighway vehicles found in construction, farming and mining, have functions controlled directly by computer systems that need to communicate with the outside world (Figure 1). These mobile environments are harsh, so the computers must be robust with small footprints to fit into narrow, space-constrained locations. Reliable transmission in a fast-moving means of transportation is considerably more difficult than in a stationary or slow-moving vehicle. However, improved technology in embedded computing continues to gain ground, providing optimal solutions for efficient transportation management. Rugged computing systems offer the best combination of form, fit and function to ensure proper fail-safe operations, with mission-critical computers supporting safe driving techniques, fleet oversight and vehicle maintenance, for example.
A True Information Highway
Wireless technologies typically networked by fieldbuses like CAN bus are now commonly used in the control computers within these vehicles to perform vital functions. Communication computers are mostly based on standard Ethernet, while the external link can be connected using one of many different wireless standards including GSM, GPRS, LTE and WLAN, to name a few. Dynamic information systems are

providing today’s connected fleet with information on the current traffic or weather conditions for better operations and allowing for fast, effective rerouting. And Internet access points required to transmit the data along can be easily integrated into these advanced computing systems, keeping the main office up to speed on a vehicle’s status for on-the-fly modifications to scheduling.
Hauling a Different Kind of Cargo
Any mobile vehicle is faced with space constraints, and with more functionality being pushed into each vehicle, highly reliable systems that can most efficiently utilize this space are definitely in high demand. A computing trend increasingly being used in transportation and fleet management environments is rugged, modular box computers. This concept allows a dense computing system to be tailored to a specific application and then enclosed in a rugged housing to withstand the rigors of a mobile environment. Not only can the electronics be customized, but the housing dimensions are adaptable enough to enable a precise fit into the compact areas of virtually any vehicle application. In addition, these environments typically mandate fanless conductive-cooling within the given application, which the box computer concept can accommodate through its design elements. From small units with 3.5” displays up to computers with 10.4” screens or
larger, box computers are providing a variety of transportation applications with advanced connectivity not seen in this area before. Because a dense set of electronics can be designed into a sealed, rugged enclosure, fleet managers are able to take advantage of the latest in embedded computing functionality. These computing solutions easily handle the vast amount of information available on 3G, and even 4G, data networks, enabling on-road access to realtime traffic information so trucks can be rerouted to stay on schedule or to precise GPS location providing an accurate delivery time to a waiting customer. Because the components and functionality of these box computers are contained within a sealed housing, the unit needs to perform reliably in not only rugged environments, but over long periods of time as well. These pre-integrated systems are designed to be put in place and operate effectively. The time and effort spent getting the system up and running is of no use if it constantly needs maintenance, especially when that system is on a vehicle in transit.
Where the Rubber Meets the Road
A box computer is configurable and can be tailored to almost any application in the transportation, construction or agriculture markets as well as to any required standards in each industry. A box PC for the rail market, for example, can
be equipped with rugged M12 connectors and a power supply compliant to the EN 50155 standard. For utility vehicles, box PCs can be certified according to ISO 7637-2 (E-mark) and come with an automotive power supply unit. Some fleet management operations are taking this newfound freedom of technology one step further. An increasing number of mass transit vehicles are being equipped with driverless systems to optimize travel speeds and frequency, and lower energy consumption. Automatic train operation (ATO) systems in the railway industry, for example, are typically based on modular systems because they control a multitude of functions such as status data continuously sent to the control center, or the capture of data from the wayside sensors, while communicating with wayside equipment (Figure 2). In one driverless underground application, up to 500 mobile and stationary control and management systems are needed to monitor the train on a line. The control and monitoring system provides a response channel that allows the permanent transmission of status data from the vehicles back to the control center. Reliable wireless communication is key to system operation, so the electronics need to function under extreme temperature and operational conditions. Aboveground driverless buses are quickly being implemented through box computing solutions, as well. And with the speed and direction of a bus being
FIGURE 2 As access to data across vehicle networks increases, more functions are being controlled remotely, from simple vehicle diagnostics to fully automated driverless systems.
RTC MAGAZINE RTC MAGAZINE OCTOBER JULY 2013 2014
controlled via electronics, high safety levels are required, so the system will operate effectively and ensure safe passenger transit. This is achieved by housing more than one single board computer in a system to ensure redundancy and continued operation if a failure were to occur. Again, the highly dense box PC concept enables this level of functionality to be cost-effectively incorporated into an enclosed computing system. The box computer concept from MEN Micro, for example, is simple and versatile—take a CPU board equipped with an AMD or Intel processor that fits the application, combine it with an I/O board featuring the connectors needed, then wrap it into a rugged fanless housing adaptable to the vehicle’s space requirements.
Keep on Truckin’
The ability to easily adapt the computing system as well as the housing leads to a cost-effective method for implementing the latest technologies in modern fleet management environments. Once hooked up via wireless methods, these systems can collect critical data and transmit it back to a central office to help with vehicle diagnostics as well as manage schedules more efficiently. Conversely, a main operator can send information to the entire fleet at any given moment for optimum—and total—fleet management. Several different implementations have already been successfully deployed. In one instance, a fanless, SCADA-based automotive data logger is used to record and preprocess information in trucks and buses. Information from one, or several, vehicles is sent to the headquarters via the Universal Mobile Telecommunications System, indicating the vehicle’s status and position as well as when its next scheduled maintenance is due. Application-specific functions, such as CAN bus interfaces, are implemented as IP cores in the onboard FPGA. Another application incorporates a compact design into a fully custom rugged 3.5” housing to provide universal control for a wide variety of commercial vehicles and mobile machines, including utility vehicles, mining trucks and construction machines. If required, this box PC can be customized with a display in sizes ranging

from 7” to 15” with support for a range of interfaces including Ethernet, USB and UART as well as graphics and audio I/O. In mass transportation, panel PCs used for driver desk systems can interface with the passengers as well as the main office, displaying content and video streams to keep all parties informed of schedules, upcoming stations or weather at a certain destination. In addition to providing outbound system information, these systems simultaneously keep the driver informed of critical operational tasks including fuel consumption and vehicle diagnostics.
Data Delivery for Specific Operations
Multiple data sources are now available between a central office and the vehicles in its network, so harnessing and processing all this data in also an important aspect when implementing a computing solution. What may be critical to the freight-related transportation industry that covers a wide geographic area may not hold true for what is important in a mass transit environment, which may be more regionally focused. Through implementing different functionality within a modular structure, the flexible box computer provides a means to achieve a cost-effective solution designed specifically for each application. In the case of a nationwide trucking operation, functionality within an on-vehicle system should include an interface to a satellite network to ensure widespread data transmissions. The ability to maintain data signals and accurate positioning
through tunnels would be an advantage as well, and if used in a system internationally, the ability to interface with multiple global systems, such as GPS, GLONASS and the upcoming European Galileo system, would be of exceptional value to a fleet manager. A large display is probably not a priority (Figures 3). However, a system used for a regional transportation operation that involves a large concentration of vehicles in a smaller geographic area will benefit from scalable box computers that can graphically display route alternatives should traffic or weather become factors that impact scheduling and delivery times. In many cases, because the control electronics in a box PC concept are directly attached to the back of the display, bigger screen sizes or other aspect ratios can be easily adjusted. Box computing systems provide bestin-class, flexible computing solutions encased in a housing that not only fits into a space-constrained vehicle application, but that is designed to withstand significant environmental conditions and long-term transit situations, as well. With modern, robust electronics making their way into an increasing number of mobile vehicles, highly dense box computing systems that can harness modern data networks will continue to be a driving force in fleet management efficiency.

TECHNOLOGY DEVELOPMENT Fleet Management Systems
Fleet Management Sees Impact of Integrated Devices and the Internet of Things Fleet management is poised for dramatic growth, fueled by the Internet of Things and a need for differentiated performance in a consolidating market. Developers are responding with highly integrated solutions that blur the lines, differentiating devices used for in-vehicle tracking and enabling more competitive, real-time services provided in the field.
for connectivity and a handheld component for use outside the vehicle. Antenna extension cables might also be part of the system, keeping a device with limited portability connected to the vehicle’s wireless signal. For example in the trucking industry, dash-mounted computing units often have a pendant that can be removed for field use, although the device stays connected with a spiral cord similar to an old telephone cable. An extensive range of software applications complete the multipiece hardware solution; these options could facilitate mapping and routing, or access to industry-specific applications and databases such as fingerprint scans, vehicle records or motorist information. Rugged PCs are well-established as in-vehicle computing solutions, yet the market has demonstrated a need for a more versatile option that is lightweight, display-oriented and connected. Instead of multiple devices—for example a fix-

s technology becomes more agile at collecting, sharing and acting on real-time information, the definition of fleet management has evolved in step. Today’s market is steadily expanding from its traditional focus on managing delivery and logistics to improving operations for law enforcement, first responders, public utility service vehicles, cable providers and more. Just about any business with a mobile presence or employees in the field can compete more effectively with greater access to information—using data to improve efficiencies, increase safety, reduce maintenance cost and improve customer service. The emergence of the Internet of Things (IoT) has had real impact in this arena, and fleet management is taking the lead as a major growth market for connected embedded applications. To better capitalize on this promise, a shift is becoming evident—systems are moving away from complex, multi-equipment so-

lutions and toward all-in-one, high-performance devices that offer compact performance and value. Streamlined, rugged and creatively designed for high-endurance environments, fleet management devices are evolving to incorporate the high performance of a traditional PC-based system, along with improved display options and easy portability. Coupled with a smaller footprint, these highly integrated devices are providing a new competitive edge in the field, blending traditional fleet management functions with smarter connected embedded services and applications.
Defining Next Generation Fleet Management Devices
Current fleet management solutions typically require several elements to accomplish desired performance in the field. From the hardware perspective, a fleet driver might have to manage not only a rugged laptop, but also a gateway device
FIGURE 1 Adlink’s IMT-1 integrates the high-performance TI OMAP5432 1.5 GHz dual-core ARM A15 processor and Android operating system. The open system architecture of the Android OS allows system integrators to easily develop applications, supporting fleet management operators with state-of-theart management applications, safer operations and regulatory compliance. Plus, TI OMAP processing power has ensured that other data- and graphicintensive applications such as certain mapping software also runs efficiently on the IMT-1 tablet PC.
mount system plus another device for tracking shipment as deliveries are recorded throughout the day—new options optimize this varied performance into a simple, integrated system. Today, a single device can achieve the same powerful connectivity to enable vehicle diagnostics while also acting as the handheld interface for other field service applications.
Familiar, All-In-One Performance
Optimized in-vehicle displays today offer the familiar look and feel of a consumer tablet, following the path of consumer electronics by doing more with a single device (Figure 1). However, this familiar interface also supports powerful built-in performance for devices that are sunlight readable and offer specifications for industrial use, such as IP54 rating for resistance to dust and water. Gorilla glass touchscreens are thicker than a typical consumer display, making them impervious to damage in the field. These rugged features combine to reduce the fleet operator’s total cost of ownership and enable faster return-on-investment in fleet management systems. Most importantly, this level of integration, ruggedness and performance is enabling a significant shift in the fleet management industry. Fleet operators no longer face such a daunting task—which historically included installing a gateway in the vehicle, fixing a rugged laptop to the dashboard or console, and training employees on using and syncing a handheld device that supplements the system with data collected when it’s removed from the vehicle and used onsite. Compact, all-in-one devices are offering a simple, more intuitive method of in-vehicle computing—not only blending processes with field service applications, but also substantially reducing the space, cost and deployment challenges associated with a larger, multi-piece deployment.
Expanding the Market
Solving the need for rugged, integrated solutions is essential, enabling fleet management applications to continue their evolution, as well as to expand into new markets. While transportation and
logistics services are foundation markets for fleet management, the opportunity for market growth is broad; integrators anticipate fleet technology to cross industry sectors such as academia, government, waste management, public transportation, utilities, retail, logistics, construction, mining, oil/gas and chemicals. Even though the fleets themselves may vary greatly (e.g., limousines, fire trucks, ambulances, law enforcement, cable repair, utility service), basic management applications are relatively consistent. The overarching goal is to keep vehicles on the road using the best routes, track and manage maintenance in a timely and cost-effective manner, and keep drivers safe by tracking behavior and addressing issues with increased training. At the same time, fleet management is expanding to include all types of field service, such as on-site medical support for first responders. Using fleet management tools, emergency personnel can send vital diagnostic information or imaging results directly from the ambulance to the hospital destination. Receiving staff can better prepare for their arrival with the proper treatment options and equipment. Ambulance personnel can even re-route more effectively if the situation warrants, for example, diverting to a facility equipped with specialized treatment options for a particular injury or medical situation. Consequently, fleet management developers are now focused on creating designs that integrate these priority performance requirements for logistics providers—focusing mainly on the two primary functional uses of an in-vehicle device. This includes the more sophisticated features such as monitoring and retrieving engine stats and employee driving habits, as well as more fundamental features such as verifying what was delivered and when. Monitoring engine performance and driver behavior is more challenging because it requires a fleet management device that is carefully harnessed into the vehicle; devices are connected and synced to the vehicle, gathering high-level diagnostic data. Some fleet management systems are taking this a step further, capturing video or sending a live video feed.
This is one application with significant potential for police and first responders, who can gather timely and accurate eyewitness statements via video or can capture real-time surveillance video to make arrests and provide evidentiary material to ensure conviction. Even fundamental logistics applications such as verification of delivery are improving with higher performance devices. Consider the delivery shipment that is damaged in transit and refused upon delivery; with capture of the right realtime data, a replacement delivery can be managed immediately instead of after data is reviewed and lengthy paperwork is processed. As industry research firm, Telematics Update, pointed out in a recent report that the data collected by fleet management applications can be almost overwhelming to operators. The real-time ability to “manage by exception” is an important benefit, building value in connected in-vehicle devices and growing the market further.
Growing with Improved, Flexible Connectivity
Fleet management is considered an extension of intelligent transportation design—applying IoT ideals to extract greater value from connectivity. Versatile wireless support is required, allowing in-vehicle devices to connect via wireless local area networks (WLAN) protocols including IEEE 802.11 b/g/n, as well as wireless wide area network (WWAN) such as 3.5G HSPA+ and 4G LTE. For example, Adlink’s IMT-1 industrial mobile tablet incorporates all of these protocols, as well as support for high-frequency (HF) 13.56 MHz NFC radio frequency identification (RFID), which allows highspeed data capture to enable fleet management operators to read the vehicle’s RFID tag and schedule appropriate maintenance activities. High-speed connectivity allows drivers to seamlessly provide and access realtime information, such as instantly correcting mistakes that can reduce costly paperwork and delays. Further, integrated GPS and e-compass technologies ensure shipments are delivered on time by opti-

mizing driver routes, and enabling monitoring by the operator. Customers awaiting delivery or service can be alerted in real time to drivers running late or early, a simple communication that can elevate the public perception of a company as being at the top of its game.
Rugged, High-Performance Solutions
Real-world scenarios for in-vehicle devices include extensive tablet usage as the driver is unloading materials, stacking boxes, moving shipments in and out of loading docks and offices, or just visiting customers in the field. Dropping the tablet is a given, and so resistance to damage from dropping is a specific requirement for the device’s rugged capabilities. For a device to be interchangeable from in-vehicle mounting to a handheld interface for field services, it must be droppable from hip height, 0.8 meters or about 2.5 feet, onto a hard surface. Industry feedback suggests that designs should ideally extend this 1.2 meters or about 4 feet; however, this must be done while the device remains sensitive to portability. Tablets can indeed be designed to handle this requirement directly, but—in the process— they become bulky and lose some of their ergonomics and elegance. These details matter significantly for real-world usability. As a result, competitive designs may opt for an add-on bumper case to extend resistance to drop height, allowing better consideration to keeping the device light and easy to handle. Integrated devices also include greater visual performance, including camera capabilities in the tablet itself. Built-in megapixel cameras on the front and rear of the device again mirror the flexibility and familiarity of a consumer tablet. In the event of a damaged delivery, image recording provides a simple means of documenting the damage right onsite, avoiding costly delays in service. Ordering or delivering replacement items right away again distinguishes the provider with better customer service. Data- and graphics-intensive applications such as image processing and mapping software are efficiently managed with Android-based devices, today capitalizing
OCTOBER JULY 20142013 RTC MAGAZINE RTC MAGAZINE
on both ARM processors and current lowpower x86 processor options. Low power is a key enabler in IoT designs, enabling high performance in thermally sensitive, passively cooled designs that truly can go anywhere.
The Business Case for a Connected Fleet
Research firm Markets and Markets recently announced details of a fleet management market study, suggesting the market is anticipated to build dramatically over the next several years, growing from $10.91 billion in 2013 to $30.45 billion by 2018. This corresponds to a Compound Annual Growth Rate (CAGR) of 22.8% during that timeframe. What are the challenges to winning a segment of this monumental growth? Increasing efficiency, ensuring compliance and promoting safety are top priorities for any design to win market share. Keeping up with capacity may be less discussed but is just as important—freight must be moved efficiently from any number of key transportation arteries that impact public health and safety. These stations include freight terminals, seaports, motor carrier hubs and airports, and further test the capacity of road, rail, air and waterways. Picking up and moving freight in a timely manner limits congestion in these transportation corridors. However, the operators that provide land transport and domestic inland distribution can compound congestion problems if they are not operating at peak performance. Further, the market is undergoing extensive consolidation demonstrated by ongoing mergers and acquisitions worldwide. Partnership is also prevalent, as new entrants to the market recognize the opportunity for leadership in working with manufacturers. By providing services and software to complement fleet management hardware, these partnerships are enabling new revenue streams for the fleet industry. For developers, supporting these issues with rugged, integrated devices is an essential piece of the shifting industry picture—embracing the Internet of Things with flexible solutions that offer a foundation for both in-vehicle connectivity and field service applications.
Moving the Market Forward with Integrated Devices
Comprehensive, compact in-vehicle solutions are driving growth, supporting multipurpose improvements that create a competitive edge. When behind-thewheel behavior is tracked, driver safety can improve with training targeted to specific issues. When routes are planned and managed for improved efficiency, organizations can reduce energy consumption and their associated carbon footprint. Real-time data creates a new ability to manage by exception, rather than sifting through mountains of information to determine how to improve operations in an ongoing manner. Customer service improves as a result of all these internal benefits, providing a tangible differentiator that exceeds the competition and improves business overall. The possibilities are expanding exponentially for operators—and designers—who are connecting customer-facing employees with effective fleet management. Using a single integrated device, operators can access and manage data for enterprise-wide improvements in performance, services and revenue. This is quickly evolving from the basics of fleet dispatch such as scheduling, load management, driver and vehicle tracking and effective routing. New performance improvements such as automated processes, image-based shipment tracking and video capture are just a few of the innovations yet to come, and they are anticipated to add broad industry value and opportunity. For fleet operators, capitalizing on IoT connectivity and highly integrated devices enables a competitive edge in this transition—reducing costs, improving performance and distinguishing compact systems that handle both in-vehicle and field service applications.

Dealing with Data: Big and Important
The Lifecycle of Live Data With the increasing integration of embedded devices with the Cloud, it is necessary to differentiate between live, actionable information and data with ongoing value. In order to realize the true power of the Cloud, businesses must utilize the power of the collecting and controlling computers on the edge of the grid. by Wayne Warren, Raima
he rise of the Cloud has presented companies of all sizes with new opportunities to store, manage and analyze dataâ€”easily, effectively and at low cost. Data management in the Cloud has enabled these companies to reduce their in-house systems costs and complexity, while actually gaining increased visibility on plant and processes. At the same time, third-party service organizations have emerged, providing data dashboards that give companies â€œlive real-time controlâ€? of their assets, often from remote locations, as well as historical trend analysis. Consider, for example, a company at a central location with a key asset in an entirely different or isolated location. It may be advantageous to monitor key operational data to ensure the equipment itself is not trending toward some catastrophic fault, and some performance data to ensure output is optimal. That might be relatively few sensors over all, and perhaps some diagnostics feedback from onboard control systems. But getting at that data directly might mean setting up embedded Web servers or establishing some form of telemetry. And then we must get that data into management software and deliver it in a way that enables it to be acted upon. How much easier would it be to simply provide those same outputs to a

Cloud-based data management provider, and then log in to a customized dashboard that provides visualization and control, complete with alarms, actions, reports and more? And all for a nominal monthly fee. Further, with virtually unlimited storage in the Cloud, all data can be stored, mined, analyzed and disseminated as reports that provide unprecedented levels of traceability (important to many sectors
of industry) and long-term trend analysis that can really help companies to boost performance and, ultimately, improve profitability. As our data output increases, it might seem reasonable to expect that the quality of information being returned from the Cloud should improve as well, enabling us to make better operational decisions that improve performance still further. And RTC MAGAZINE JULY 2014
FIGURE 2 Wind turbines are examples of systems that need data both for immediate control to keep up with things like changing wind conditions and for longer term analysis such as parts wear and trends that may signal need for maintenance.
to an extent, this is true. But there is also danger on that path because as we move into an era of Big Data, it is becoming increasingly difficult to pull meaningful, “actionable information” out from the background noise. Where once a data analyst might simply have been interested in production line quotas and the link to plant or asset uptime, today they may also be interested in accessing the data generated by the myriad of automated devices along the production line. That is because that raw data may well hold the key to increased productivity, reduced energy consumption, elimination of waste, reduction in down time, improved overall equipment effectiveness, and ultimately a better bottom line. And we really are talking about huge amounts of data. The rise of the “Inter-

net of Things” and machine-to-machine (M2M) communications, combined with the latest GSM networks that deliver highspeed, bi-directional transfer without the limitations of range, power, data size and network infrastructure that once held back traditional telematics solutions, has seen data transmission increase exponentially in the last few years. As of 2012, across the globe over 2.5 exabytes (2.5x1018) of data were being created every day, and it is certainly not unusual for individual companies to be generating hundreds of gigabytes of data. Importantly, different types of data will have different lifecycles, and this impacts how that data needs to be managed. The phasor measurement devices, for example those that monitor the variables on the power grid that highlight changes in frequency, power, voltage, etc., might gen-
erate perhaps a few terabytes of information per month. Certainly this is a lot of data, and it has a mixture of lifecycles— long-term information indicative of trends as well as live data that can immediately flag a fault. A complex product test, by contrast, might generate the same volume of information in an hour or less, but again there will be a mixture of data lifecycles; the complex information that provides a pass/fail output for the test needs to be immediately available to optimize production cycles, but has no value subsequently, while the overview information might be important to store for traceability reasons. The common thread, however, is the large amount of data being generated. Indeed, this is so much information that it is no longer meaningful to measure today’s data in terms of the number of records, but rather by the velocity of the stream. Live
data—that is, captured data about something happening right now—is available in great quantities and at low cost. Sensors on embedded and real-time computers are able to capture information at a rate that exceeds our ability to use it. That means that the moment for which any given volume of data has real value may well come and go faster than we can actually exploit it.
Data from the Edge
If our only response is to simply send all of that data to the Cloud with no regard for the life cycle of the data, then the Cloud becomes little more than a dumping ground for data that may well have no ongoing value. It is vital, then, to consider the lifecycle of live data, and how that data is best distributed between embedded devices and the Cloud. For Cloud resources to be truly optimized while enabling meaningful operational decisions to be made locally, in the moment, then the power of embedded systems on the edge of the grid must be fully utilized. Only by delegation of responsibilities for data collection, filtering and decision making to the increasingly powerful computers deployed within the Internet of Things can we have effective management of data from its inception to disposal. The embedded database industry has responded to this requirement with data management tools that deliver the requisite performance and availability in products that are readily scalable. These data management products can take the captured live data, process it (aggregating and simplifying the data as required) and then distribute it to deliver the visualization and analytics that will enable meaningful decisions to be made. The ability to do all of this locally within embedded systems—acting on data that is only of real value in the moment—has a huge impact on the performance of plant and assets, while the data that has ongoing value can be sorted and sent to the Cloud. Consider, for example, the testing of consumer products where the way the product sounds or feels is taken as an indicator of its quality. Such quality testing is common in a host of domestic and automotive products, which possess intrinsic vibration and sound characteristics that may be used
as indictors of mechanical integrity. A part under test might be subjected to a period of controlled operation while measuring millions of data points. A multitude of metrics and algorithms need to be applied to this data to create a “signature,” which determines whether the product passes or fails the quality check. Raima was involved in just such an application, in a market where production cycle times were critical and where new data sets were being generated every two seconds. The live data had to be acted on in real time to match the required production cycle time while providing reliable pass/fail information. At the same time, it is important to aggregate, manage and store the essential test information for the long term so that in the event of an operational fault or a customer complaint, the product serial number can be quickly checked against the test history. It is important to be able to reprocess the historical data when considering warranty costs or perhaps even the need for a product batch recall. This is a very clear differentiation of data lifecycles (Figure 1). When we talk about performance, we do not necessarily have to think about real-time response in a deterministic sense for streaming data, but we must have live real-time response that is simply fast enough to work with live information that appears quickly and has a short lifecycle. The database might need to be able to keep up with data rates that may measure thousands of events per minute, with burst rates many times higher, and must able to raise alarms or trigger additional actions when particular conditions are met. Those conditions might involve the presence or absence of data in the database, so quick lookups must be performed. They may also depend on connections between records in the database, so the database system needs to be able to maintain associations and lookups that can be quickly created or queried. The high-speed processors in modern computer systems play a part, but increasingly meeting performance requirements depends on scalability, which comes from the ability to distribute the database operations across multiple CPUs and multiple processor cores. This not only makes best
use of available resources, but also opens up possibilities for parallel data access, allowing very fast throughput. Now look at the example of wind turbine control, where operators need to constantly monitor variables such as wind speed, vibration and temperature (Figure 2). Because wind turbines are often in remote locations and are unmanned, a database is required that can store large amounts of data—perhaps in the order of terabytes per day—and that will continue to operate reliably 24/7 without intervention. The data storage system must therefore support replication (from turbine controllers to wind farm controller), as well as remote, secure access. The database is critical at several different levels. First, it is central to the control of the wind farm, controlling the turbines through the wind turbine control database into which a row that sets the turbine’s operational status and describes the current wind conditions is inserted and replicated to each of the turbine control programs. This is based on live data with a very short lifecycle. Then there is condition monitoring on the turbine itself, providing critical information on the operation of the asset and enabling, for example, cost-effective scheduled or pre-emptive maintenance that maximizes uptime. The datastream is live, with high volumes of data, but it needs to be aggregated and analyzed to produce trend outputs and alarms. Finally, there is the storage and monitoring of historical data that will enable the development of next generation wind turbines that are more robust and more fault tolerant. This data has very little value in the moment, but has a very long lifecycle—appropriate for storage in the Cloud. RDM Embedded from Raima meets all of the requirements for managing live streams of data, providing a platform that enables both live real-time decisions to be taken and long lifecycle data to be sorted and then sent to the Cloud. The database engine is capable of storing incoming data reliably while allowing the same data to be read for analysis, possibly from remote systems, or else via replication. Platform independent, it can run on everything from popular OS options such RTC MAGAZINE RTC MAGAZINE OCTOBER JULY 2013 2014
as MS Windows, Linux and iOS to realtime systems such as Wind Rivers’s VxWorks, QNX Neutrino and Green Hills Integrity, as well as many others. As well as supporting multiple processor and multicore architectures, the RDM data storage engine provides a set of data-organizing features that can be used to control in-memory, disk-based or remote storage to provide the best possible performance in an embedded system application. Importantly, RDM makes data available wherever it is needed. RDM can replicate data between computers on a network and via the Internet to systems outside the embedded network environment. This can be used to improve the speed of processing, data backup security and system-wide data availability. While the Cloud is the ideal environment for storing, managing and analyzing data that is less time-sensitive or which has ongoing value, meaningful handling of live, time-sensitive data with a much
shorter lifecycle is much better provided by local embedded database systems. Only when companies are able to analyze and act upon this critical data can they have the information needed to truly optimize plant, process and production operations. In this Big Data era, the businesses that are the most successful in reaping the benefits of those large volumes of information will be those that are able to discriminate between time-sensitive data and data with ongoing value, and then integrate their embedded systems and Cloudbased systems effectively to ensure the appropriate data is always going to the right place. Only by embracing the power of the computer systems at the edge of the grid can companies really optimize the power of Cloud resources. Raima. Seattle, WA (206) 748-5300. www.raima.com
