Title:
BEARING FAILURE DIAGNOSIS METHOD AND DEVICE, READABLE STORAGE MEDIUM, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/061006
Kind Code:
A1
Abstract:
Bearing failure diagnosis method and device, a readable storage medium, and an electronic device are provided. The bearing failure diagnosis method includes: acquiring a vibration acceleration signal of a bearing which is running (S101); performing wavelet decomposition to the vibration acceleration signal of the bearing to obtain a plurality of signals (S102); extracting feature parameters from the plurality of signals respectively and constructing feature vectors (S103); constructing a feature matrix based on the feature vectors (S104); feeding the feature matrix to a trained neural network model (S105); and comparing an output result of the trained neural network model with a predetermined target matrix to obtain a failure diagnosis result of the bearing (S106). Accuracy of bearing failure diagnosis may be improved.
