The project is designed to control over the railway level crossing gate using Android mobile phone by the gate keeper. Opening and closing of railway level crossing gate involves manpower, which could be often causes incorrect leading to accidents. This system prevents the need of any human involvement at the railway level crossing. This system involves opening and closing of the level crossing gate by using an Android app. This Remote operation is achieved by any smart-phone/Tablet etc., with Android OS, upon a Graphical User Interface based touch screen operation. A Bluetooth device is interfaced with the system. When the gate keeper sent command to close from the Android application device (when the train is approaching at the level crossing) to the Bluetooth device which while supply to the microcontroller, sends an output signal which activates a mechanism to switch on the motor to close the gate. To open the gate, another command needs to be sent for the microcontroller to open the gate using motor driver integrated circuit. In this project we use a microcontroller of 8051 families, and the input to its Bluetooth device which takes command from the user Android application. The output to microcontroller is given to a motor by using a motor driver integrated circuit for some required operation. The status, whether the gate is open or close is displayed on an LCD (liquefied crystal display) interfaced to the microcontroller.
