DEVELOPMENT/Railway Transport 70 LOGO!based automatic control system for the sliding gate
By Sven Dummer
By Yurii Kizilov
The article provides a detailed description of how to build a specialized embedded Linux distribution in the crossplatform environment. Also discussed are the unob vious sources of risks and hidden costs when using a "rollyourown" approach to build the inhouse Linuxplatform. The article compares the "rollyourown" and commercial approaches based on the example of the Wind River Linux platform.
SYSTEM INTEGRATION/Metallurgy 28 System for measuring temperature and oxidation and melt sampling in an electric steel furnace through the working door
The article presents an automatic control system for the sliding gates at the railway transport maintenance facility. The system is based on LOGO! module and employs the remote radio control principle. Also discussed in detail is the system operation algorithm under various situations and at different inputs.
HARDWARE/Drives 74 Explosion protection of the nonelectrical parts of the equipment based on the sliding monitoring By Stefan Pflueger
By Sergey Chistyakov, Sergey Sinyavin, Aleksei Savin and Dmitriy Kirkin
The current international standards specify the explosion protection of the non electrical parts of the equipment. A risk of explosion can occur when the drive and the output device of the system are interlocked. The article analyses the potential consequences of such interlock and evaluates the potential ignition sources. Also discussed are the explosion protection solutions based on the rotational speed monitoring in order to identify the signs of sliding, an indicator of occurrence of a dangerous situation. The article covers the commercial modules for implementation of such solutions.
The article describes one of the options for designing an automation system which is intended for contact measurements and melt sampling and replicated for various process facilities at the Cherepovets Iron and Steel Plant. Also discussed are the special features of the manipulator control system. The article gives reasons for preference of the SIMATIC controller, discusses the operating principles of the measuring instruments, shows the software capabilities and specifies the development tools.
SYSTEM INTEGRATION/Oil & Gas Industry 36 Problems and solutions on the upgrade of Sputnik and Mera AGMU in the oil industry
HARDWARE/Sensors 78 Buoy or guided wave radar? By Vitaliy Grigorchuk
By Boris Andreychikov The current stage of the technology development in the oil industry is characterized by working out the ways to upgrade the automatic group measuring units now in operation and the new ones by using moisture meters. The article describes the architecture, operation algorithm and evaluation of the accuracy of measuring the flowrate and relative content of crude oil in the products from the oil producing wells by means of Satel RVVL radiowave moisture meter specifically designed for this purpose. Also included are the performance characteristics and the results of the certification tests.
Today the buoy level gages are one of the most common devices that can be used to measure levels of any liquids in industry. When using these devices, the instrument engineers face the maintenance problems. What is an alternative solution to reduce costs and optimize the measurement process?
PORTRAIT OF THE COMPANY 80 MEN Mikro Elektronik: solutions for critical applications By Aleksei Pyatnitskikh The article presents MEN Mikro Elektronik Gmbh as one of the leaders in manufacturing the reliable systems and components for harsh environments. The business indicators given in the article, information on the partners as well as description of the recent developments and unique solutions are provided to show the innovative activity of MEN Mikro Elektronik Gmbh, fundamentals of manufacturing high quality and reliable products, and a comprehensive approach to developing the reliable control systems for critical applications.
SYSTEM INTEGRATION/Electric Power Industry 50 Process control system of the Yumaguzinskaya Hydropower Plant By Evgeniy Lobachyov The Republic of Bashkortostan, the Bashkiria National Park in the Kugarchinsky District here, in this place, the hydrologists decided to realize their dreams and implement their "hydro thoughts". That is how an idea to implement the high technologies and in future, the process automation equipment for power generation came into being and finally, the Yumaguzinskaya Hydropower Plant was built at the bottom of the hydro engineering complex on the Belaya River.
