Description

Technical Field

[0001] The present invention relates to the field of urban rail transit operation and maintenance, and in particular to an operation and maintenance system for network-level communication signals of mega-city rail transit. Background Art

[0002] The normalized high-intensity operation of the super-large-scale network has put forward corresponding higher requirements for equipment maintenance. The main points are as follows: 1. Single-line single-point faults in super-large-scale networks are easy to spread in a network, and operations have extremely high requirements for the reliability and usefulness of equipment and facilities; 2. The number, types, and scenarios of equipment in super-large-scale networks are diverse and complex, and the risk of equipment abnormality increases, and the difficulty of maintenance increases; 3. The operating mileage of super-large-scale networks continues to grow, and the corresponding maintenance costs are also growing; 4. Passengers in super-large-scale networks are highly dependent on rail transit, and have comprehensive requirements for safety, convenience, punctuality, comfort, and operating hours, which also puts forward higher requirements for equipment maintenance time, efficiency, and quality. An intelligent network-level maintenance platform is needed to assist professional technicians and maintenance commanders to solve the difficulties of the above equipment maintenance. The intelligent operation and maintenance platform needs to realize online, real-time, accurate, and high-frequency equipment status perception and monitoring to accurately grasp the working status of the equipment in the entire network. It is necessary to establish a big data center for equipment operation status, use long-term sedimentation data, summarize equipment operation rules, and generate maintenance recommendation reports. Utilize the conclusions from equipment operation data analysis to carry out targeted equipment tuning, rectification and optimal design.

[0003] In practical applications, the research and development of the intelligent operation and maintenance platform for urban rail transit communication signals on ultra-large-scale lines still faces the following technical problems:

[0004] 1) Scalability: As the scale of rail transit networks continues to expand, the number of vehicles and stations on the lines has also increased significantly. Therefore, the network-level intelligent operation and maintenance platform must be able to accommodate the increasing size of data.

[0005] 2) Customized terminals: The line-level intelligent operation and maintenance platform is aimed at a wide variety of end users, including professional and technical workers, emergency repair commanders, and they need to view and retrieve data across lines and stations. Therefore, user terminals must be flexible and can be quickly customized to avoid the need for a large amount of custom development work.

[0006] 3) Diverse data types and structures: The line-level intelligent operation and maintenance platform needs to cover the status perception data of all relevant equipment, both structured and unstructured, such as real-time data on equipment status and video streaming data, so the platform must support the access and persistence of multiple forms of data.

[0007] 4) Easy to expand: Ultra-large-scale urban rail transit networks usually have more than 10 lines, so the platform needs to achieve expanded access to new lines while ensuring that it does not affect the lines that have already been connected. Summary of the invention
