Objective The urban rail transit network-level power dispatching system has gained widespread research and application. To ensure the safe and reliable operation of the power supply system, the anti-misoperation technology for electrical equipment is crucial. However, existing research on anti-misoperation systems specifically for the urban rail transit network-level power dispatching scenario remains relatively limited. Therefore, it is necessary to conduct application research on anti-misoperation in network-level power dispatching.

Method Targeting the urban rail transit network-level power dispatching system, an SOA-based （service-oriented architecture） anti-misoperation system is designed based on the SophiCloud industrial internet platform. In-depth analysis is conducted on key anti-misoperation technologies, including conventional verification, signal interlocking, logic rule interlocking, and topology verification. Meanwhile, specifically addressing topology anti-misoperation verification, related technologies such as topology search based on graph data structures and graphical generation of operation tickets are emphatically studied.

Result & Conclusion  Relying on the service bus of the SophiCloud industrial internet platform, the development of the SOA-based operation anti-misoperation system for urban rail transit network-level power dispatching is completed. The proposed multi-level anti-misoperation verification system integrating signal interlocking, logic rules, and topology verification, has been applied in multiple urban rail transit network power dispatching projects. This anti-misoperation system for power dispatching operation can effectively suppress the risks of remote misoperation in the power supply system and improve the level of operational safety.
