Detection System of Leakage in Crude Petroleum Pipeline Based on Hybrid Wavelet Features Analysis

With the advantage of multi-scale and multi-resolving power of wavelet transform,the leakage features of crude petroleum pipeline were extracted by wavelet analysis.Using the regression method,the real-time measured data of pipeline leakage can be analyzed and recognized.The location can be obtained by the extracted hybrid features.The experiments show the validity of the proposed method.
