General detection and fault diagnosis method and system for rail transit vehicle equipment

Abstract

The invention discloses a rail transit vehicle equipment universal detection and fault diagnosis method and a system thereof. The method comprises the following steps: signals acquired through a data acquisition module are input to a fault diagnosis module to obtain a fault diagnosis conclusion; an expert system rule base is arranged in the fault diagnosis module; and a plurality of rules relevant to faults are stored in the expert system rule base; the expert system rule base adopts fault trees to represent the interrelationship of the various rules; a fault diagnosis process is served as a data matching process based on importance degree; the acquired data and the rules in the expert system rule base are matched from the highest importance degree to the lowest importance degree; if the matching is successful, a matching result is output and a fault conclusion is given out; and no fault occurs if the matching is not successful after the whole rule base is browsed. The rail transit vehicle equipment universal detection and fault diagnosis method and the system have good universality and are quick in fault diagnosis.

Description

technical field [0001] The invention relates to a general detection and fault diagnosis method and system for rail transit vehicle equipment. Background technique [0002] The rapid development of my country's railways has not only increased the railway mileage and the total amount of railway transportation, but also increased the rolling stock under the jurisdiction of various railway bureaus. With the development of urban rail transit in major and medium-sized cities, subway light rail vehicles are also increasing rapidly. These massively increased rolling stock models include not only the previous DC Shaoshan series, but also various types of AC Harmony locomotives and CRH EMUs that have recently been put on the road, as well as various urban rail subway vehicles. For the safe operation of vehicles, all vehicles need to be overhauled after running for a certain period of time. Existing rolling stock models are numerous, but most of the existing maintenance equipment of ...
