Smart Railway Track Monitoring for Real-Time Crack Detection Using GSM and GPS

Railway track safety is a critical concern for preventing accidents and ensuring smooth train operations. This project presents a robot-based crack detection system that autonomously detects cracks and obstacles on railway tracks and communicates the information to authorities in real time using GSM and GPS technology. The system employs a microcontroller-based robotic platform equipped with crack sensors for detecting surface discontinuities, IR sensors for obstacle detection, a GPS module for precise location tracking, and a GSM module for sending instant alerts. The robot navigates along the track using motor drivers and DC motors, and detected cracks are displayed on an onboard LCD. Experimental testing demonstrates that the system can effectively identify cracks of various sizes and accurately transmit the location data, enabling prompt maintenance actions. The proposed system enhances railway safety, reduces human inspection efforts, and provides a reliable, real-time monitoring solution.
