Railway Track Security by GSM With User Programmable Number Features Working:  Two rails forming the part of a track are made using a pair of wire, connected with a detachable jumper in between each wire/track.  Removing the detachable jumper creates a fault in the respective path; otherwise it is shorted by the jumper wire to stimulate healthy track condition.  Removing the jumpers result in driving transistors delivering a different logic to the controller.  The program after that takes over to send an sms through gsm modem interfaced through a level shifter ic to the microcontroller. http://www.edgefxkits.com/

Railway Track Security by GSM With User Programmable Number Features  An LCD will be interfaced with the MC in order to display the status of GSM and track condition.  Thus, the proposed model is designed to recognize the cracks in the railway tracks and provides instant information to the concerned railway authorities.  The power supply consists of a step-down transformer 230/12v, which steps down the voltage to 12v ac. It is converted to DC using a bridge rectifier.  The ripples are removed using a capacitive filter, and it is then regulated to +5v using a voltage regulator 780s that will be required for the operation of the microcontroller and other components. http://www.edgefxkits.com/

Railway Track Security by GSM With User Programmable Number Features Power Supply: ďƒ˜ There are many types of power supply. Most of them are designed to convert high voltage AC mains electricity to a suitable low voltage supply for electronics circuits and other devices. ďƒ˜ A power supply can by broken down into a series of blocks, each of which performs a particular function

Railway Track Security by GSM With User Programmable Number Features Transformer:  Transformers convert AC electricity from one voltage to another with little loss of power. Transformers work only with AC, and this is one of the reasons why mains electricity is AC.  Step-up transformers increase the voltage, step-down transformers reduce the voltage. Most power supplies use a step-down transformer to reduce the dangerously high mains voltage (230V in UK) to a safer low voltage.  Transformers waste very little power, so the output power will be equal to the input. Note that as the voltage decreases the current increases.

Railway Track Security by GSM With User Programmable Number Features Rectifier:

 There are several ways of connecting diodes to make a rectifier convert AC to DC. The bridge rectifier is the most important, and it produces full-wave varying DC.  A full-wave rectifier is made from two diodes using center tap transformer. But this method is rarely used now because of diodes cheap availability.  A single diode can be used as a rectifier, but it only uses the positive (+) parts of the ac wave to produce half-wave varying dc.

Railway Track Security by GSM With User Programmable Number Features Gsm Communication:  The term GSM usually means the GSM standard and protocols in the frequency spectrum around 900MHz.

Mobile Station:  The MS is the physical equipment used by a subscriber, most often a normal hand-held cellular telephone.

Base Transceiver Station:  The BTS comprises the radio transmission and reception devices, and also manages the signal processing related to the air interface. http://www.edgefxkits.com/

Railway Track Security by GSM With User Programmable Number Features Gsm Modem:  A GSM modem is a specialized type of modem which accepts a SIM card and operates over a subscription to a mobile operator, just like a cell phone.  From the mobile operator perspective, a gsm modem looks just like a mobile phone.  When a gsm modem is connected to a computer, this allows the computer to use the gsm modem to communicate over the mobile network.  While these gsm modems are most frequently used to provide mobile internet connectivity, many of them can also be used for sending and receiving sms and mms messages. http://www.edgefxkits.com/
