1. Auto Operated UNMANNED level crossing for RAILWAY network

.SYNOPSIS:

 

AUTO OPERATED UNMANNED LEVEL CROSSING FOR RAILWAY NETWORK:

OBJECTIVE:  

           The main objective of this project is to avoid accidents at railway crossing junctions.

INTRODUCTION:

            Now a days railway accidents are happening at the crossing junctions due to the negligence of the operator, to avoid this, this system is developed so that it detects the railway some prescribed distance away from the junctions and closes the crossing gates on its own and offers, the train is passed it reopen the gate.

  FUNCTIONAL BLOCK DIAGRAM: 

FUNCTIONAL DESCRIPTION:

                     The system consists of two pair of IR Tx & Rx at some predefined distance away from the crossing junction and just next to the junction. As train passes through the sensors, the receiver produces a pulses and are detected by the microcontroller and the motor is driven to close the gate, and when the train is been passed completely and is detected by the second pair of sensors and the gate is reopened by driving the motor in other direction.

         

HARDWARE REQUIRED:
