Title:
DEVICE FAULT DETECTION METHOD BASED ON BASELINE DATA SPACE
Document Type and Number:
WIPO Patent Application WO/2023/226213
Kind Code:
A1
Abstract:
Provided in the present invention are a device fault detection method based on a baseline data space. The method comprises: determining a working condition parameter, which has a preset correlation with a working condition of a device; according to a fixed-length time period of the working condition parameter of the device, discretizing a set of original data of the acquired working condition parameter of the device, and generating a set of discrete working condition parameters that include a plurality of pieces of fixed-length time period data; according to the set of discrete working condition parameters and acquired signal data of the device in a normal state, constructing a baseline frequency domain data space of the device in a normal state, and setting a fault determination threshold value; and calculating an over-limit difference value assessment index, comparing the over-limit difference value assessment index with the fault determination threshold value, and determining whether the device has a fault. In the present application, a complex working condition is decomposed and discretized, so as to reduce the influence of multiple working conditions on fault feature extraction, fault identification, etc., and a fault is visually responded to by means of an over-limit difference value space, such that related service personnel can understand and grasp fault information and the deterioration degree of the fault more easily
