Wavelet change point detection-based wavelet analysis method and system, and storage medium

The invention discloses a wavelet variable point detection-based wavelet analysis method and system and a storage medium, and the method comprises the steps: selecting a primary wavelet function, selecting an optimal decomposition layer number according to a to-be-analyzed sequence and a primary decomposition layer number, and carrying out the optimal decomposition layer number through a sequence consistency detection method according to the to-be-analyzed sequence. And optimizing an optimal wavelet function from the plurality of candidate wavelet functions, and performing wavelet analysis by using the optimal decomposition layer number and the optimal wavelet function. The method is simple and easy to implement, key parameters determining the wavelet transformation accuracy can be rapidly screened out by means of the advantages of integrating the wavelet function and the decomposition layer number through wavelet point change detection, the calculation steps are few, the calculation efficiency is high, the m
