AIM:
This project takes control over the unmanned railway crossing by giving great preference to the safety of train
as well as road vehicles.
Working principle
The railway gate is opened and closed automatically using microcontroller. The microcontroller is
programmed such that it gets the indication of train‘s arrival and departure through the wireless sensor unit. The
sensor unit is a composite unit controlling IR sensor and RF communication. The RF transmitter transmits the
encoded sensor signal to microcontroller unit sensor unit when train has trespass the sensor. . The
microcontroller unit receives and decoded the transmitted signal. With reference to the signal received the gate
is either closed or opened along with an alarm. Whenever the signal received gate IR sensor is activated to
check whether any vehicle is there in front of the gate before the gate is closing. If any vehicle is there in front
of the gate the train signal will be in RED till the gate is open i.e. the vehicle has crossed the gate, a the signal
status is transmitted to the nearest railway station the communication used here is GSM.
