    Design And Implementation Of A Solar-Based Railway Track Crack Detection System Using Ultrasonic Sensor
    (Department of Electrical and Electronic Engineering, 2018-12) SHOVON, MOHAMMAD ABDUL AHAD; HASAN, RAFI
    In Bangladesh, railway communication is very important due to its low cost involvement. But there is an accident issue as well which a real concern for this sector. In the current railway system, it is more necessary to have safety elements in order to avoid accidents. One of the important causes that can provoke serious accidents is the existence of crack on the track. At present, the cracks in the railway tracks is checked by manual system. Therefore, this project works deals with one of the efficient method to avoid train accident and crack detection. The design of while system consists a Global Position System (GPS) module, Global System for Mobile (GSM) module and Ultrasonic sensor. In this project work, ultrasonic sensor is used to detect the crack in the railway tracks by measuring distance from track to sensor, If the distance is greater than the assigned value, then the microcontroller identifies there is a crack. The longitude and latitude of the track location is messaged to the nearest railway station using GPS and GSM module. It is an effective and cost efficient system for railway applications
