Advanced Railway Signaling System

Abstract

Railway transportation is a vital aspect of modern society, and safety is a significant concern in railway operations. One of the critical safety components in railway transportation is the signaling system, which controls the movement of trains on the tracks. Traditionally, the signaling system utilized metal contact-based sensors placed on the tracks to detect the passage of trains. When the train wheels move from one track to another, the sensors change the signals. The signal changes from green to yellow and then to red when the train moves past the sensor. However, this traditional signaling system has its limitations and challenges. One of the challenges with the traditional signaling system is the changing of signals, which has led to accidents and track changes. To address these limitations and challenges, this thesis proposes a new railway signaling system that replaces the traditional metal contact-based sensors with radio frequency identification (RFID) technology. The proposed system includes coder and decoder circuits that communicate wirelessly with RFID cards attached to the train. The system is designed to change signals automatically based on the movement of the train, reducing the likelihood of accidents and track changes. In the new system, the RFID cards are attached to the train, and as the train moves from one track to another, the wireless contact between the RFID cards and the poles trigger the signal changes.
