摘要：
A new method based on cubic B-Spline dyadic mother wavelet of centro-symmetric about zero is presented, the Principle of singularity detection by using wavelet transform modulus maximum is applied in railway catenary fault feature extraction by using the mother wavelet, at last, the project is concluded by using BP neural network to recognize pattern. The result shows that it can confirm position accurately and identify the fault types effectively.
