Abstract
The project highlights the technology that prevents train collisions using the distance measurement between trains on the line. The KAVACH system consists of RFID readers in locomotives plus radio frequency communication that transmits the data to the TCAS (Train Collision Avoidance System) at the station and the locomotive cabs. The report states one constraint of the current KAVACH system is that it cannot fetch the data for trains on loop or diversion tracks. To resolve this, the project proposes an upgraded system that uses sensors for detecting whether a train is on diversion or mainline track. This information will then be sent to the locomotive cabin and displayed on the dashboard as messages to take necessary actions. This project substitutes radio communication with WiFi-based wireless data transmission in SIMPLEX communication, where one ESP32 microcontroller is the transmitter while another one is the receiver. This is intended to improve railway safety by delivering real-time track information to locomotive operators, thereby saving them from accidents like the one that happened in Balasore.
