AUTOMATIC RAILWAY GATE CONTROLLING SYSTEM

Abstract
             The objective of this project is to manage the control system of railway gate using the micro controller. The  control system activates and closes the gate on either side of the track. once the train crosses the other end control system automatically lifts the gate. For mechanical operation of the gates dc motors  are employed. Here we are using embedded controller built around the 8051 family (AT89C52) for the control according to the data pattern produced at the input port of the micro controller, the appropriate selected action will be taken..       The logic is produced by the program written in Assembly language. The software program is written, by using the KEIL micro vision environment. The program written is then converted in HEX code after simulation and burned on to micro controller.

The basic idea behind this project is an automatic railway gate at a level crossing replacing the gates operated by the gatekeeper. It deals with two things. Firstly, it deals with the reduction of time for which the gate is being kept closed. And secondly, to provide safety to the road users by reducing the accidents. By the presently existing system once the train leaves the station, the stationmaster informs the gatekeeper about the arrival of the train through the telephone. Once the gatekeeper receives the information, he closes the gate depending on the timing at which the train arrives. Hence, if the train is late due to certain reasons, then gate remain closed for a long time causing traffic near the gates.
