Application of wavelet transform in the signal identification of hoist brake staff

The method of oil pressure signals and displacement signals denoised by wavelet shrinkage was presented. Because wavelet shrinkage has multi-resolution advantage, the noise existed in the signals can be reduced largely. Addition, in order to recognize the value of brake oil pressure,wavelet transform which has the advantage of better singularity detection was described. Through these methods described, the good effects of signal denoise and recognition of the value of brake oil pressure were obtained from example.
