The Solar-Based Railway Track Fault Detection System is designed to enhance railway safety by detecting track faults, obstacles, and abnormal vibrations in real time using a renewable energy source. The system is powered entirely by solar energy, making it efficient, eco-friendly, and suitable for remote areas where continuous power supply is a challenge. An Arduino microcontroller acts as the central unit, integrating various sensors such as IR sensors for track crack detection, an ultrasonic sensor (SR04) for obstacle detection, and a vibration sensor to monitor unusual track conditions. Solar energy is captured and stored in a rechargeable battery through a charging circuit. This stored energy is used to operate the system. An LM2596 buck converter is used to step down the 12V battery voltage to 5V DC, which powers the Arduino and other modules. In this project, two railway tracks are considered, and each track is equipped with an IR sensor for fault detection. When a track fault or abnormal vibration is detected, the system immediately stops the motorized unit to prevent accidents. Additionally, a GPS module is used to determine the exact location of the fault, and a GSM module sends an alert SMS along with location details to railway authorities for quick response and activates a buzzer for warning. The tracking system consists of a GPS receiver, microcontroller, and GSM module. The GPS receiver provides location information in terms of latitude and longitude. When an obstacle is detected using the ultrasonic sensor (SR04), the system activates a buzzer for warning and automatically stops the vehicle. The status of the project will display on LCD. The entire operation is controlled by a microcontroller programmed using embedded C language.   This system ensures improved railway safety through early fault detection, automatic control, and real-time communication, thereby reducing the risk of railway accidents while utilizing sustainable solar energy.        

The main objectives of the project are:

  To detect railway track faults using IR sensors.

  To identify obstacles on the track using an ultrasonic (SR04) sensor.
