Vehicle state evaluation method and system based on rail transit vehicle fault data

Abstract

The invention relates to a rail transit vehicle fault data-based vehicle state evaluation method and system. The method comprises the following steps of 1) constructing a basic information base and a vehicle function structure of all vehicle types of a whole line network; 2) constructing a vehicle fault library covering all vehicle types of the whole network; 3) acquiring historical fault data of the electric train, and counting the number of faults after preprocessing; and 4) constructing an electric train state evaluation model, and calculating the overall state score of the electric train in combination with the fault frequency and the fault quantification level. Compared with the prior art, the method and system have the advantages of grading, effective classification management, objective and scientific evaluation, improvement of working efficiency, fault analysis and query and the like.

Description

Technical field [0001] The present invention relates to a train track state detecting electric field evaluation, in particular to a rail vehicle based on the vehicle failure data evaluation method and system status. Background technique [0002] In the context of the rapid development of urban rail transit, rail transit vehicles and vehicle management base increases showed uneven development trend. Especially for urban rail transit into the city earlier, has the full realization of network operation, net assigned many models, the useful life of the vehicle in all aspects, design and manufacturing standards, device status, operational performance, maintenance requirements, etc. There are differences . As the vehicle operator of the most important urban rail transit equipment, vehicles to assess not only one of the means to protect urban rail transit operation safety, but also the situation in terms of reliability, availability and serviceability reflect on the whole vehicle, such ...

AI Technical Summary

Problems solved by technology

Urban rail transit vehicles are a collection of complex mechanical systems and electrical systems. The vehicle state is affected by many factors. As a complex dynamic system, it is difficult to obtain the failure physical model of the vehicle; therefore, the vehicle state is obtained mainly through monitoring or Assess the state of a certain subsystem or component in the vehicle system, but for the vehicle as a whole, the subsystem or component cannot fully reflect the health status of the vehicle. At this stage, the assessment of the state of the vehicle is still in the exploratory stage
