Correlation Analysis in Water Pipeline Leak Detection and Location of the Application

Pipeline leak detection and location technology have an important position in the supply pipeline safety.In the paper,the application of correlation analysis method is used in pipeline leak detection and location technology with negative pressure wave method.De-noising treatment of leakage signals can filter lots of noises by using sliding average and wavelet analysis methods.The noises are extracted from leakage signals based on employing negative pressure wave method.Simulation results show that:according to actual situation,choosing reasonable de-noising method can improve the alarm and positioning accuracy of correlation analysis methods in the water pipeline detection.
