Abstract: In response to the difficulties and weak links in equipment maintenance and management of the turnout of track and communication and signaling combined section, this paper designed and developed an active operation and maintenance system for the turnout of track and communication and signaling combined section, elaborated on the system architecture and key technologies, and implemented functions such as collecting detection and monitoring data, evaluating equipment status, and verifying operation. The actual on-site trial situation shows that the system can break through the information silos of track department and communication and signaling department in the equipment management of the combined section, implement mutual coordination in the operation and maintenance management process of multiple specialties, actively push equipment maintenance operation plans, assist the equipment management department in optimizing production organization, and improve the quality and efficiency of equipment maintenance in the turnout of track and communication and signaling combined section.
