Research on Electromagnetic Compatibility of Wireless Transmission in High-Speed Railway Train Control System Based on Knowledge Graph

In the high-speed railway environment, electromagnetic interference poses a significant threat to radiocommunication within train control systems, leading to critical security concerns for railway transportation and passenger safety. To tackle the electromagnetic compatibility challenges of wireless links in complex circumstances, a method based on knowledge graph for analysis and management is proposed. This method establishes an electromagnetic compatibility knowledge graph for the wireless transmission in the railway train control system by representing the three elements of electromagnetic compatibility as triple information in the graph database. Furthermore, the application of the knowledge graph is discussed with practice cases. This approach offers a thorough and efficient electromagnetic compatibility analysis framework for the wireless transmission in train control system, supporting the stable operation and safety of the high-speed system.
