The Application of Wavelet Transform on the Pipeline Leakage Detection and Localization
【摘要】 介绍了一种基于小波变换的输油管道泄漏检测与定位系统,根据小波变换与信号奇异性之间的关系,采用小波变换模极大值算法对输油管道的压力信号进行奇异点检测,利用检测到的奇异点进行泄漏的定位。
【Abstract】 A leakage oil pipeline detection and locating system based on Wavelet transform is introduced.According to the relationship between the Wavelet transform and signal singularity,it uses the modulus maxima algorithm of the Wavelet transform to detect the Singular point on the Oil pipeline’s pressure signal.The system can realize the leakage localization with the Singular point.
