Urban rail door system fault or sub-health diagnosis method and system

Abstract

The invention discloses an urban rail door system fault or sub-health diagnosis method and system, and the method comprises the following steps: building an urban rail door system door opening and closing electromechanical combined virtual prototype, and comparing door opening and closing experiment data to correct model parameters; setting different working conditions, and constructing a vehicledoor fault or sub-health model; and with a simulation result as a learning sample, extracting a characteristic value, constructing a door system fault or sub-health diagnosis model by applying an intelligent algorithm, and removing redundant characteristics; collecting fault or sub-health experiment data to verify the accuracy of the sample analysis and diagnosis model; based on the fault or sub-health diagnosis model, diagnozing the running state of the main line vehicle door, and providing an urban rail door system fault or sub-health diagnosis system. According to the diagnosis method and system, vehicle door fault or sub-health diagnosis research is carried out by means of the virtual simulation result, the defects of long physical experiment period, high cost and the like are avoided,the operation reliability of the vehicle door system is improved, the research and development period is shortened, and the development cost is reduced.

Description

technical field [0001] The invention relates to a fault or sub-health diagnosis method and system for an urban rail gate system, in particular to a fault or sub-health diagnosis method and system for an urban rail gate system. Background technique [0002] With the development of the rail transit industry, the safety and reliability of the operation of urban rail car doors have received extensive attention. The high-frequency use of door systems, complex vehicle operating environment and unknown human causes make the number of door failures account for more than 30% of the total number of vehicle component failures. Therefore, improving the quality and reliability of the door system operation is of great significance for the efficient and safe operation of urban rail trains. [0003] At present, the method commonly used in the fault research of urban rail vehicle door system is to collect historical data or experimental data of vehicle door operation under different working...

AI Technical Summary

Problems solved by technology

In this method, the source of the door operation data often requires a long door operation period, or a large number of physical tests based on the bench, which has the disadvantages of limited space, long test period, and high cost.
