A System for Surveying Railway Track Geometry Using Multi-sensor

In the proposed system the monitoring of the railway tracks is proposed which can reduce the human labor. By this system the cracks in the railway tracks are detected and also the condition of the track is monitored without any help of the human. When a crack is detected by the IR sensor then a message is sent to the specified person through an SMS. In this processes the location of the crack is obtained using the GPS module and the obstacles in the path are avoided using the ultrasonic sensor, the direction of the robot is obtained by the MEMS sensor
