REVIEW PAPER ON RAILWAY TRACK CRACK DETECTION ROBOT USING IOT

Electronics and Telecommunication Engineering

In India railways transportation service is the cheap and the majority convenient mode of passenger transport and also for long distance and suburban traffic. The Indian Railways consists one of the largest railway networks in the whole world, crises-crossing over 1, 15,000 km in distance, all over India. In country like India, where majority of people depend on railways for transportation, if a crack in railway track is not detected during the early stages they may lead to derailment causing heavy loss to human life and property. Almost 24 million passengers use the railway system on a daily basis. The main cause of the accidents happened in railways are railway track crossing and unrevealed crack in railway tracks. Therefore, there is a need to have new technology which will be robust, efficient and stable for both crack detection in railway track as well as object detection. Our work involves a project that aims of designing a railway crack detection system (RCDS) using Ultrasonic Sensor, GPS (Global Positioning System) and Node MCU ESP8266 Wi-Fi module whose implementation is an efficient method of detecting the cracks which is present in the tracks and thus avoiding derailment of the trains. Crack detection by this method can be done during both day and night time and ex act location of fault can be obtained.
