In this paper, the selection conditions of wavelet bases in wire rope breakage signal analysis are given. The characteristics of B-wavelet and the theoretical basis of linear B-wavelet in wire rope breakage signal analysis are given. Experimental results show that using B-wavelet analysis to distinguish internal and external broken wires successfully, it also improves signal-to-noise ratio and real-time performance of digital signal processing and the accuracy and robustness of quantitative identification.
