Abstract: Urban rail transit signal equipment requires restart during daily maintenance and fault recovery. To further improve the efficiency of equipment restart, this paper designed a remote restart control system for urban rail transit signal equipment. The paper respectively introduced the system structure, core functions and key technologies adopted, and analyzed the application effect of the system. The system ensures the safety of equipment restart operations through a series of process control and authority control; through the client-side graphical interface, it facilitates operators to check equipment status, issue restart commands and perform authority management. The system has been successfully applied to a line of Tianjin Metro, which not only greatly improves the maintenance efficiency of maintenance personnel, but also effectively ensures the safety of restart operations, providing strong support for the digital operation and maintenance of urban rail transit signal equipment.
