Outline
In response to the increasing operation and maintenance pressure and efficiency requirements of urban rail transit, a comprehensive management and control platform based on digital twins and multisystem integration is constructed and implemented to achieve intensive and refined operation and maintenance management of subway stations and improve management efficiency and service levels. Through 3D scanning of existing lines, this paper focuses on the development and implementation of an integrated management and control platform based on digital twin technology and multisystem integration, enhancing management efficiency and service quality. Firstly, a digital twin model is constructed to represent the operation of urban rail systems. The study explores model lightweight technology and uses 3D rendering engines to render and optimize large models and large scenes. In addition, this paper studies multisource heterogeneous data fusion technology through data standardize processing to realize the processbased collection and storage of heterogeneous data of various professions. Furthermore, a comprehensive urban rail management and control platform is developed, integrating functional modules to meet the needs of various disciplines. This platform improves the execution efficiency of operation and maintenance tasks by 30%, increases the accuracy of equipment and facility status monitoring to 98%, and increases the success rate of preventive maintenance by 20%. The efficiency of cross-disciplinary data sharing and collaborative work is enhanced by over 60%, resulting in a shortened fault response time, significantly improved accuracy of equipment and facility status monitoring, and enhanced effectiveness of preventive maintenance.
