Android Controlled Railway Level Gate Control Using 8051

Our project aims at a railway level crossing gate opening/closing system operated through an android application. The opening/closing of railway gate is traditionally operated through manual lever pulling method. This method leads to a lot of accidents due to the rational technique and lever jamming. The system allows user to easily perform this operation through the use of a simple android based application. It operates by providing the opening and closing functionality of a railway gate by sending commands through an android application. The remote controlling application is provided through an android application. This application just any android OS based device to run on. Bluetooth device attached to the railway gate is used to receive the Bluetooth commands. These commands are then passed on to an 8051 microcontroller which then performs the required action. On receiving opening command, it drives the motors to open the gate and closes the gate on receiving the close commands. It does this by driving the motor through a driver IC to achieve this functionality. Moreover even the status of gate needs to be seen. So the system is also integrated with an LCD display in order to display weather the gate is open or closed.
