Problems solved by technology

[0005] In the existing technology, the diagnosis results of the components to be detected are rough and imprecise, especially the problematic components cannot be detected in the initial stage of hidden dangers
In addition, subjective evaluation is generally used for components after maintenance, which cannot reflect the quality of components after maintenance.

Abstract

The invention discloses a rail transit vehicle maintenance system and method, and the system comprises an information storage unit, an information collection unit, a health diagnosis unit, a maintenance unit, and a maintenance quality evaluation unit, and the health diagnosis unit comprises a model training module, an audio classification module, an ultrasonic image enhancement module, and a diagnosis module. A diagnosis result is obtained by adopting the sound enhanced ultrasonic image, a maintenance quality evaluation model is established by adopting the appearance data, the material performance and the welding process data of the maintained part, and the rating of the maintained part is obtained. The method is accurate in diagnosis result and objective in evaluation result.

Description

technical field [0001] The invention relates to a rail transit vehicle maintenance system and method, and belongs to the technical field of rail transit vehicles. Background technique [0002] Rail transit refers to a type of vehicle or transportation system in which operating vehicles need to run on specific tracks. During the operation of the vehicle, affected by factors such as service life and environment, the health status of some key components will gradually deteriorate. If maintenance is not performed in time, it may eventually lead to failures. In rail transit systems, maintenance plans are based on regular Maintenance and breakdown maintenance are the main focus, which makes the maintenance plan not flexible enough, and it is impossible to eliminate the health hazards of vehicles in the operation process in a timely and effective manner. [0003] Chinese patent CN201911070794.8 discloses a subway vehicle operation and maintenance system, which includes an automati...
