Dynamic equipment digital-analog dual-drive fault diagnosis method based on mechanism and data

The invention provides a dynamic equipment digital-analog dual-drive fault diagnosis method based on mechanism and data, and the method comprises the following steps: S1, obtaining the structural characteristics of dynamic equipment, and carrying out the fault mechanism analysis and high-dimensional feature extraction according to a typical fault type; s2, performing mechanism-based diagnosis according to fault mechanism analysis; s3, performing data-based diagnosis according to the high-dimensional feature extraction; s4, establishing a mechanism and data-based dynamic equipment digital-analog dual-drive fault diagnosis model; and S5, performing fault diagnosis on the dynamic equipment by using the dynamic equipment digital-analog dual-drive fault diagnosis model based on the mechanism and the data. The model is adopted to diagnose the fault of the dynamic equipment, so that facts and rules stored in a working memory can be combined to establish a reasoning model, new information is reasoned, and an automati
