AUTOMATIC RAILWAY TRACK SWITCHING USING STEPPER MOTOR CONTROL

The project involves automatic track switching in railways using stepper motor control. The project is designed to avoid railway accidents happening at unattended railway gates, if implemented in spirit. This project utilizes a powerful IR transmitter and a receiver. Two sensors are placed at either sides of the junction where the track switches. If there’s a train approaching from the other side, then the sensor placed along that direction gets activated and will send an interrupt to control the motor. The interrupt service routine switches the track. Indicator lights have been provided to avoid collisions. Here the switching operation is performed using a stepper motor. Assuming that within a certain delay, the train has passed the track is switched back to its original position, allowing the first train to pass without any interruption. This project can be further extended to automatic railway gate control.
