Intelligent Operation and Maintenance System of an Urban Rail Transit Based on Cloud-Edge-Terminal

The demand of equipment-intelligent operation and maintenance is urgent in terms of the operation of a urban rail transit network. This study proposes an equipment-intelligent operation and maintenance system for an urban rail transit based on a cloud-edge-terminal frame. The system uses cloud-edge collaboration technology, and some cloud center functions are translated into edges to realize the rapid response and effective application of terminal data by combining the advantages of cloud and edge computing technology. The system integrates equipment-monitoring, equipment-health management, equipmentintelligent analysis, and emergency command platforms as well as an expert system. The system can monitor equipment statuses online, evaluate equipment health, intelligently diagnose faults, intelligently predict faults, and intelligently analyze and adjust emergency commands. The system can reduce the equipment failure rate, improve the equipment operation and maintenance efficiency, and ensure the safe operation of rail transit networks. It can serve as a significant reference for improving the equipment-intelligent operation and maintenance level in urban rail transit.
