Oil Pipeline Leakage Location Based on Wavelet Transform Algorithm

Pipeline leak cases not only influence the normal operation,result in natural resource waste,but also bring serious damage to natural environment.So wavelet transform was adopted to detect and locate pipeline leakage.The two falling point position difference between the two negative pressure wave was got by the position difference of two module maximum on biggest scale.This algorithm not only can locate leakage,but also delete the influence of noise,and attest the availability of the algorithm by simulation.
