Problems solved by technology
[0003] However, at present, the overhaul and maintenance of urban rail trains mainly rely on manual inspection of the running part of the train.
This inspection and maintenance method is not only costly but also inefficient, and it is also easy to miss inspections due to blind spots observed by the human eye.

The invention provides a rail train maintenance and detection system based on computer vision. The system comprises a cleaning module for sensing, cleaning and drying a train body, a data acquisitionmodule for acquiring video image data of a train, a machine vision unit for analyzing and detecting cracks and part conditions on a running part of the train, and a control unit for controlling othermodule units to detect and clean the train. The cleaning module is used for washing sludge and impurities on the running part of the train, a camera device of the data acquisition module is used for shooting the running part of the train, and a video image of the running part is transmitted to the machine vision unit, so that the machine vision unit detects the cracks and the part conditions on the running part of the train. The running part of the train can be automatically, quickly and efficiently checked. The checking and maintenance mode for the running part of the train is low in cost andhigh in efficiency, the condition of missing detection caused by a blind area observed by human eyes is avoided, and the overhauling accuracy can be effectively improved.
Description
technical field [0001] The invention relates to the technical field of urban rail trains, in particular to a computer vision-based rail train maintenance detection system. Background technique [0002] Urban rail trains, such as subways and urban rail trains, are the main body of urban passenger dedicated line transportation, and their technical performance is directly related to the speed and safety of trains. Therefore, it must be fully unified, comprehensive and accurate control and detection to ensure its normal work. The running part is one of the most important components of the subway, and its condition directly affects the running quality, dynamic performance and driving safety of the urban rail. Therefore, the detection of the running part of the urban rail train is an important guarantee to ensure the safe and reliable operation of the subway transportation network. [0003] But, at present, also mainly rely on manually to check the running part of the train to t...
