Abstract

The embodiment of the invention provides a high-speed rail driving equipment fault diagnosis method and device. The method comprises the steps: extracting fault features from one or more collected original data signals of high-speed rail driving equipment based on a signal analysis method; performing preliminary fault diagnosis on the high-speed rail driving equipment based on a classifier according to the fault feature of each original data signal, and acquiring a preliminary diagnosis result corresponding to each original data signal; and fusing the preliminary diagnosis results corresponding to all the original data signals based on a multi-sensor fusion algorithm to acquire the final diagnosis result of the high-speed rail driving equipment. According to the embodiment of the invention, automatic fault diagnosis is carried out on high-speed rail driving equipment, and the diagnosis result is accurate.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a fault diagnosis method and device for high-speed rail driving equipment. Background technique [0002] The cyber-physical system of high-speed railway traffic safety monitoring is a multi-factor interactive, dynamic and real-time system. The three basic simple and static components of trains and lines become complex dynamic composite systems. Any factor in the system is no longer a meaningful factor. With the expansion of time and space, the imbalance of dynamic driving effects makes the The risk of the system is enlarged, the operability is weakened, and the matching is loose. [0003] The imbalance of the interaction of any factors in the system will lead to high-speed railway accidents. Therefore, the mechanism of high-speed railway accidents, the safety and reliability analysis of relevant operators, the safety analysis of driving equipment, ...
