This work was supported by the State 863 Program (2003AA148040), the National Natural Science Foundation of China (grant number 10471151,60216263, 6990312), New Century Excellent Talent Support Project of Chinese Ministry of Education, Doctor Station Foundation of Chinese Ministry of Education, Chongqing Tackle Key Problem Program and Chongqing Natural Science Foundation.
In general, oil pipelines are partially or completely buried under the ground, due to many reasons such as rust and breakage, leakage accident happens frequently. Aiming at this problem, this paper utilizes wavelet transform technology to analyze and process pressure signals, and detects the leakage by using negative pressure wave method to locate the leakage position, it is effective and exact.
