Research on Water Pipeline Leak Location


Article Preview

With the accelerated process of urbanization, water pipeline leak problem becomes more and more serious. If this problem dose not solved in a timely manner, water resource waste, even serious geological disasters will be caused. In order to locate the water pipeline leak position, we studied the characters and mechanism of the leakage acoustic signals in this paper, and analyzed the spectrum characters of acoustic signal with different leakage quantity and noise on pipeline diameter sudden change point. Based on this, we designed and implemented a set of software, using wavelet denoising method and cross-correlation time delay estimation method for leak location. Finally, we conducted an experiment based on the cast iron pipeline with a diameter of 1.5 inch using the proposed software, and compared the results obtained by different processing approaches. As a conclusion, the experiment results and the theoretical expectations are basically the same.
