Embodiment Construction
[0036] The following is a detailed description of the embodiments of the present invention. This embodiment is carried out based on the technical solution of the present invention, and provides detailed implementation methods and specific operation processes to further explain the technical solution of the present invention.
[0037] The invention provides a fault diagnosis method for an industrial system based on multi-sampling rate sensor data fusion, such as figure 1 shown, including:
[0038] 1. Construct a training sample set
[0039] Obtain the historical original sequence output by multiple sensors preset in the industrial system and the corresponding industrial system fault types; for each fault type, N time segments with a time span of T are randomly selected from the historical original sequence, and different sensors The data in the same time segment are spliced sequentially, and the reconstructed sequence obtained by splicing is normalized to obtain the preproce...
