Abstract
In order to solve the selection of the optimal wavelet basis for the gas pipeline leak monitoring, the feature of wavelet basis especially for gas pipeline leak monitoring and positioning has been summarized based on the analyze of wavelet basis parameters characteristic and gas pipeline leak negative pressure wave signal feature. A parameter which named reconstruction and mutation joint factor has been introduced to judge the denoising and positioning effect, and the result has been gotten: the db5 wavelet basis is the optimal wavelet basis for the gas pipeline leak monitoring and positioning. The subsequent simulation test verified the correctness of the result.
