1. Under the Guidance :- Mr.B. Suresh Babu (M.Tech) ELECTRONICS AND COMMUNICATION ENGINEERING Project Batch:- 18 D. Siva Sumanth (060429) K. N. V. Subrahmanyam (060449) J. Mahesh (060446) G. Srikanth (060438) ST.ANN’S COLLEGE OF ENGINEERING AND TECHNOLOGY CHIRALA

2.  To alert and save the people from the train accidents at the unmanned railway gates.  To restrict the train accidents by introducing an application of track switching.  This project is developed in order to help the INDIAN RAILWAYS in making its present working system a better one, by eliminating some of the loopholes existing in it.

3. Stepper motor for track switching Track Section- A Track Section - B LPC 2129 Micro controller IO pins A B Ch-1Ch-2CH-3Ch-4 Gate closed Stepper motors

4.  When the train is behind 5km the counter will tell the micro controller to send the RF packet and stepper motor will close the gate by rotating clockwise and glows red signal light.  When the train crosses the gate then the counter automatically opens the gate by rotating the motor in anti- clockwise direction.  We can use the same counter to detect two trains coming in the same track in opposite direction and with the help of stepper motor we could rotate the gear to switch the track.

6.  An axle counter is a device on a railway that detects the passing of a train instead of the more common track circuit.  A counting head is installed at each end of the section, and as each axle passes the head at the start of the section, a counter increments.  As the train passes a similar counting head at the end of the section, the counter decrements.

7.  A stepper motor is a widely used device that translates electrical pulses into mechanical movement.  Stepper motors consist of a permanent magnet rotating shaft, called the rotor, and electromagnets on the stationary portion that surrounds the motor, called the stator.

8.  There is no time lag to operate the device.  Accuracy.  This can be further implemented to have control room to regulate the working of the system. Thus becomes the user friendliness.  This circuit can be expanded and used in a station with any number of platforms as per the usage.
