[0001] The utility model belongs to the technical field of railway inspection, testing and examination, and particularly relates to a factory test platform for a network-rail-tunnel inspection system. Background Art
[0002] In recent years, the operation scale, passenger volume, length of under-construction lines and length of planned lines of urban rail transit in China have all reached new highs. The development of urban rail transit is becoming more networked, differentiated, with diversified system structures, and the network operation is gradually realized. For the traditional subway power supply, track, bridge and tunnel specialties, only after the subway line stops operating in the early morning at night can the inspection vehicle enter the track area to detect the status of catenary, track and tunnel equipment. And after problems are detected during the inspection, a maintenance operation plan needs to be declared on another day and can only be entered into the track area again to repair equipment such as catenary, rail, roadbed and tunnel after approval. Therefore, there are currently two major technical problems in the existing subway infrastructure inspection system: First, for the traditional subway power supply and track specialties, only after the subway line stops operating in the early morning at night can the inspection vehicle enter the track area to detect the status of catenary, track and tunnel equipment. This way of working not only has low efficiency, but also increases a large amount of labor costs and equipment over-maintenance costs. Second, the inspection system devices such as subway catenary and track are installed and deployed independently, and the inspection data are independent of each other. The data analysis of each system is carried out based on the data collected by this system, and the data analysis results are one-sided.
[0003] Therefore, how to improve the existing subway infrastructure inspection system to improve the working efficiency of subway infrastructure inspection, reduce labor costs and equipment over-maintenance costs, and at the same time avoid the situation where the inspection system devices such as subway catenary and track in the prior art are installed and deployed independently, the inspection data are independent of each other, and the data analysis of each system is carried out based on the data collected by this system, and the data analysis results are one-sided, is a technical problem that needs to be solved urgently at present.
