Rail transit power supply operations are mainly manual on-site operations, with frequent occurrences of accidents involving personnel injuries and equipment damage.
The increasing demand for rail transit operations and safety measures has significantly reduced the available time for maintenance work.
Manual management modes for process management, material management, equipment inspection, and work preparation are inefficient.
With the large-scale expansion of the network and the significant increase in equipment, the mismatch between O&M personnel and equipment scale leads to a heavy maintenance workload.
The rail transit power supply operation safety management system comprehensively applies new technologies such as cloud, big data, IoT, and AI, providing an overall solution to enhance the safety control and operational efficiency of power supply operations. It offers comprehensive safety management and control solutions for various rail transit power supply operations across different locations, ensuring operational safety while achieving refined maintenance management for a safe, efficient, and intelligent management system.

Comprehensive safety assurance
The power supply operation business implements full-scenario and full-process anti-misoperation interlock control, constructing a cross-space, cross-equipment safety assurance system based on the grid network.
Efficient process management
The electronic and network-based management of work tickets, operation tickets, and dispatch orders makes ticketing and circulation management more convenient and efficient.
Remote visual supervision
Centralized remote video monitoring of work processes and equipment status significantly enhances the overall control efficiency of equipment, personnel, and operations.
Applications of innovative technologies
Innovative use of topology-based anti-misoperation, machine vision, deep learning, and other new technologies enhances the reliability of production management efficiency and equipment safety assurance in power supply operations.
The crew scheduling management system uses informatized methods to optimize the management of each aspect of crew management, including the compilation of driving plans, automatic scheduling, dispatch and return status of crew members, safety training and education, query statistics, and information announcements. This forms a complete information chain, achieving centralized analysis, dynamic transmission, and information sharing of crew data. It effectively improves crew work efficiency and optimizes production dispatching command processes, realizing precise command and refined management.
This solution, designed for the power supply and maintenance operations of urban rail transit depots, adopts advanced technologies such as IoT, big data processing, automation control, computer technology, and network communication. Through monitoring, early warning, and control, it establishes a unified safety management and control platform that covers comprehensive dispatching, point management, and maintenance safety interlocking. Guided by the maintenance process of the depot, it establishes closed-loop process control, achieving real-time protection and informatization throughout the entire process to meet the goals of safe, efficient, and intelligent O&M management.
It is applicable to electrified railways, urban rail transit systems, or city rail transit lines powered by AC 27.5 kV, including mainline catenary systems, station yards, and depots (EMU depots). The solution enables automatic grounding operations during catenary system maintenance, remote visual monitoring, online voltage detection, operational safety management and control, safety interlocking, and closed-loop management of work processes. While ensuring safety, it significantly improves the efficiency of grounding operations and safety measure deployments, thereby extending the effective maintenance time for catenary systems.
By replacing conventional isolation switches, transfer switches, and visual grounding devices with a combination of intelligent isolation grounding switch devices, this solution can be applied to urban rail transit mainline catenary systems and various scenarios within depots, achieving a comprehensive visual and intelligent solution for catenary system switch devices. It significantly improves the efficiency of catenary system disconnector operations and the intelligence level of catenary system switch devices.
Suitable for urban rail transit mainline catenary systems, throat areas, and maintenance depots, this solution enables automatic grounding operations, remote visual supervision, online voltage detection, operational safety management and control, safety interlocks, and closed-loop process management during catenary system maintenance. It significantly improves grounding operation and safety measure deployment efficiency while ensuring safety, extending the effective maintenance time for catenary systems.
