There are many railway crossings which are unmanned due to lack of manpower, needed to fulfill the demands. Hence, many accidents occur at such crossings, since there is no one to take care of the functioning of the railway gate when a train approaches the crossing.The objective of this paper is to manage the control system of railway gate using the microcontroller. The proposed model has been designed using 8052 microcontroller to avoid railway accidents occurring at unattended railway gates, if implemented detection of train approaching the gate can be sensed by means of two sensors placed on either side of the gate. This work utilizes two powerful magnetic sensors; one of these magnetic sensors is fixed at upside (from where the train comes) and similarly the other magnetic sensor is fixed at down side of the train direction. Sensors are fixed on both sides of the gate. We call the sensor along the train direction as °∆foreside sensor°« and the other as °∆after side sensor°«. When foreside sensor gets activated, the sensed signal is sent to the microcontroller and the gate motor is turned on in one direction by relay driver and the gate is closed and stays closed until the train crosses the gate and reaches after side sensors. When after side sensor gets activated and the signal about the departure is sent to the microcontroller, motor turns in opposite direction and gate opens and motor stops.
