Development of railway track crack detection system

In the developing country people are facing many accidents.It would be undesirable for any nation to losing their life for unwanted cause.Railways are one of the important transports in India.There is a need for manual checking to detect the crack on railway track and always railway personnel take care of this issue, even though the inspection is made regularly.Sometimes the crack may un-notice.Because of this the train accident or derailment may occur.In order to avoid this situation and automate the railway crack detection has been proposed.Here ultrasonic sensor is used to detect the crack in the railway track by measuring distance from track to sensor, if the distance is greater than the assigned value the micro controller identifies there is a crack.Here we are Using Arduino micro controller.After crack detection or object detection the testing robotic vehicle stops and the longitudinal and latitudinal positions are sent via SMS to GSM and GPS to the control station.This project is important because it keeps trains and the people who ride them safe with this robot around, the tracks stay strong and reliable, making train travel even better
