Abstract: Objective During the operation and maintenance of urban rail transit catenary systems, various challenges such as reduced maintenance windows, high labor costs, low levels of information-based management, and significant operational safety risks will arise. Therefore, it is essential to leverage the big data generated during operation and maintenance to achieve refined management. Method By integrating BIM（building information modeling） and GIS（geographic information system） technologies, a detailed analysis of the safety management-control platform functions for catenary operation is provided. Key functions include catenary basic resume information management, development of BIM models for critical infrastructure, collection of GPS data for catenary equipment, maintenance task planning, generation of work orders/tickets, and real-time safety monitoring of on-site operations. Result ＆ Conclusion Through the adoption of advanced technologies such as SOA（service-oriented architecture）, RFID（radio frequency identification）, and IoT（Internet of Things）, the catenary operation safety management-control platform enables intelligent diagnosis and preventive maintenance of catenary status. Furthermore, by clearly defining operational scopes and consolidating work logs, the platform can enhance interoperability among systems and equipment, promote information sharing and improve business process coordination, thereby providing technical support for the refined management of catenary operations.
