A Survey on Onboard Computing Network based Railway Gate Monitoring System

The Railway Gate Monitoring System using onboard computing techniques is designed to enhance safety and automation at railway level crossings. It employs onboard units installed on trains, which are equipped with GPS, RFID, and wireless communication modules to continuously track the train's location, speed, and direction. This real- time data is transmitted to a microcontroller-based gate control unit situated near the crossing. As the train approaches, the gate automatically closes, remains shut while the train passes, and opens only after it has safely crossed. The system minimizes human intervention, reducing the risk of human error. Onboard computing enables fast and accurate decision-making based on sensor data and predefined logic. Additional sensors like IR or ultrasonic detectors can be used to identify obstacles at the crossing. CCTV integration can further monitor and record gate activity for safety audits. This project is cost-effective, scalable, and ideal for remote or unmanned crossings. Overall, it significantly improves safety and efficiency in railway transportation systems.
