The research of natural gas pipeline leak detection based on adaptive filter technology

This paper expounds the potential safety hazard of natural gas pipeline leakage, and briefly summarizes the means and defects of pipeline leak detection recently. A acoustic detection method of natural gas pipeline leak based on adaptive filtering algorithm is proposed so that the situation the natural gas pipeline leakage is difficult to find and detect can be solved. The sensor structure and flow diagram are elaborated, and pipeline leakage simulation test system was designed. This experiment processes and discriminates of leakage characteristics through the upper machine software Labview. Eventually the leak can be detected and located in fundamental.
