Moving-device fault detection method and system

Abstract

A moving-device fault detection method and system are in the technical field of fault detection. The method includes the steps of collecting a measurement signal of a target device (S10); performing fault type classification on the measurement signal on the basis of an autocorrelation characteristic (S20); on the basis of the classification result, selecting a corresponding fault diagnosis model (S30); and performing fault diagnosis on the basis of the selected fault diagnosis model and the measurement signal to obtain a diagnosis result (S40). On the basis of a fault type distinguishing result, adaptive diagnosis model selection is made to ensure that the selected diagnosis model is a fault detection model suitable for current signal feature rules.
