AUTOMATIC RAILWAY GATE CONTROL AND ANTICOLLISION SYSTEM

This Present project is designed using 8535 microcontroller to avoid railway accidents happening at unattended railway gates, if implemented in spirit. This project utilizes two powerful IR transmitters and two receivers. one pair of transmitter and receiver is fixed at up side (from where the train comes) at a level higher than a human being in exact alignment and similarly the other pair is fixed at down side of the train direction. Sensor activation time is so adjusted by calculating the time taken at a certain speed to cross at least one compartment of standard minimum size of the Indian railway. We have considered 5 seconds for this project. Sensors are fixed at 1km on both sides of the gate. When the sensor s1 gets activated, the gate motor is turned on in one direction and the gate is closed and stays closed until the train crosses the gate and reaches sensors s2. Buzzer will immediately sound at the sensor s1 activation and gate will close after 5 seconds, so giving time to drivers to clear gate area in order to avoid trapping between the gates and stop sound after the train has crossed.
The same principle is applied for anti collision system. one pair of transmitter and receiver is fixed at front end of train. consider a situation two train are travelling in opposite direction ,from both train will produce IR light from source and receiver section receives IR light then the engine stops.Image
