Abstract: Aiming at practical deficiencies in railway equipment rooms, including decentralized management frameworks, insufficient intelligent monitoring capacity, low operation and maintenance efficiency, slow fault diagnosis and localization, and the lack of proactive fault early warning capability, this paper designed and implemented an intelligent computer room safety management system based on sensor technology. The paper elaborated the overall architecture of the system. By adopting multi-source sensor data fusion technology, the system realized functions including real-time status monitoring of equipment, dynamic perception of environmental parameters, intelligent early warning of operational risks, and automatic management of operation and maintenance workflows. Practical application results verify that the system improves the intelligence level of safety management and the efficiency of operation and maintenance for railway equipment rooms, cuts operational management costs, and delivers reliable technical support for the safe and stable operation of equipment inside railway equipment rooms.
