The multi-scale qualitative features of the signal changes detected by the wavelet transform extraction process are studied, and the stability of the extracted features and the completeness of the working conditions area are analyzed and proved.A multi-scale causal reasoning model is proposed for extracting the features Causality reasoning analysis is carried out.The application of case study confirms the feasibility and effectiveness of the proposed method.
