Railway vehicle intelligent maintenance auxiliary system

Abstract

The invention discloses a railway vehicle intelligent maintenance auxiliary system, which comprises a data management module, a data acquisition device and a data transmission module, and the data acquisition device comprises a fixed scanning frame used for scanning the top and the side surface of a vehicle returning to a garage, a mobile robot carrying a detection terminal, and a mobile robot used for scanning the bottom of a static vehicle; after the data acquisition device acquires an image of a to-be-detected vehicle, the image is transmitted to the data management module through the data transmission module, after the data management module performs detection, preprocessing and feature extraction on the image, vehicle modeling is performed, and the vehicle is compared and matched with initialization information of the vehicle, so that whether the to-be-detected vehicle is damaged or not is judged. The system has the advantages that the automatic inspection of the vehicle is realized through all-directional scanning, modeling data providing, vehicle modeling and comparison, the inspection efficiency can be greatly improved, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of rail vehicle maintenance, in particular to an intelligent rail vehicle maintenance auxiliary system. Background technique [0002] The two important presentation methods of rail vehicles are the rail traffic in our cities and the rail traffic between cities. With the continuous progress of urbanization, the scale of cities is showing a trend of expansion. Rail transit has become an important part of public transportation in many cities. Many cities have established or planned huge rail transit networks. Rail transit will inevitably It will become one of the important travel methods for people in the future; and the high-speed rail has become one of the main choices for people to travel. [0003] In order to ensure the safety of operation, rail vehicles must be strictly inspected before and after passenger transportation tasks every day, including vehicle appearance inspection, parts maintenance, etc. Ins...

AI Technical Summary

Problems solved by technology

[0003] In order to ensure the safety of operation, rail vehicles must be strictly inspected before and after passenger transportation tasks every day, including vehicle appearance inspection, parts maintenance, etc. Inspection items include looseness, foreign objects, loss, oil leakage, and oil Position, sintering, deformation, fracture, damage, temperature exceeding the standard, etc., and these inspection items are mostly completed manually, the workload and work intensity are very large, and workers may make mistakes under long-term high-intensity work It will be greatly improved, which will bury safety hazards for the safe driving of vehicles.
