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

利用小波变换在突变信号处理中的优势,提取出原油管道泄漏信息经过小波变换后的泄漏点特征,运用回归分析方法,对泄漏信号的实测数据进行分析和定量识别。设计了反映泄漏信息的混合波形特征,并基于该特征实现了原油管道泄漏检测系统设计,由此定位管道泄漏位置,通过实验验证了方法的可行性。

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.
