Paper Title
Railway Level Gate Crossing Controller Using Android & GSM

Abstract
The system is constructed so as to achieve the control over the gate crossing situated at the railway level i.e. closing and opening of the crossing gates. In current scenario the gates are mostly controlled involving manpower which is usually placed at the level crossing. Here the proposed system makes use of an android platform. The working of the gate i.e. closing and opening of the gate is controlled with the help of an android application which will be on an android smart phone or a tablet. When a train is anywhere nearby the level crossing gate a SMS will be send from an android application. The SMS will be sending to the GSM modem which will interpret the SMS and it will then forward the command to the microcontroller. Then the microcontroller will feed the output signal to the motor and motor driver is switched on. It results in closing of the gate. Then for opening of the gate other command to open the gate will be given to the microcontroller through GSM modem from android application which will forward the signal to the motor driver. Here 8051 microcontroller is been used to complete the process.. Here an LCD is been used to display the current status of the railway gate i.e. open or closed which is attached with the microcontroller.
