Abstract

As the core support for rail operation control, dispatching command and passenger service, the stability of the communication and signal system directly determines the operational efficiency and safety of the line. This paper takes the communication signal interference problem of on-board equipment in rail transit as the core. Starting from the generation mechanism and evolution characteristics of interference, it classifies and analyzes three types of interference sources: electromagnetic radiation, equipment coupling, and transmission links, and reveals the dynamic evolution law of interference with the operation stage and the hierarchical penetration influence mechanism. Furthermore, the direction of technological innovation is explored from four dimensions: anti-interference design of vehicle-mounted hardware, optimization of production processes, product testing and verification, and type tests. Propose practical paths for full life cycle management, implementation of key scenarios, coordinated promotion of standards, and talent cultivation, and look forward to the development trends of intelligence, integration, and greenness, providing theoretical support and practical references for enhancing the anti-interference capabilities of train control on-board equipment such as CTCS3-300T and CTCS3-400T.
