Abstract：Railway signaling equipment is the cornerstone of the railway control systemand plays a vital role in ensuring safe and eficient railwayoperation.Improving the eficiencyoffault handling ofrailway signaling equipment is directlyrelated to improving theoverall operation and maintenance quality.The applicationof knowledge graphs in railway signaling equipment fault management provides arevolutionary method to improve fault handling effciency. Knowledge graphs can fuse various types of information， perform multi-heterogeneous information fusion，and achieve automatic diagnosis and fault-assisted maintenance through graph reasoning.This feature greatly improves the effciency of the fault management processThis article conducts an in-depth study ofthe construction process of a knowledge graph specifically designed for fault diagnosis of railway signaling equipment. It also proposes an application architecture and functional framework specifically for fault diagnosis of railway signaling equipment， making fulluseof the advantages of the knowledge graph.The framework helps integrate various data sources and supports advanced inference mechanisms to accurately identifyand diagnose faults. Inaddition，this paper illustrates the practical significance of knowledge graph-based methods in fault repair.By providing auxiliary maintenance support， the system can significantly reduce downtime and improve the reliability of railway operations.

Keywords： signal equipment; fault diagnosis; knowledge graph; multi-heterogeneous information fusion; intelligentoperationand maintenance
