输油管道泄漏检测信号的自适应滤波处理

Adaptive Filtering for Leak Detecting Signals of Pipeline

由于输油管道中信号的检测存在信噪比比较低的问题 ,通过利用自适应噪声抵消过程中广泛应用的带延迟的有限冲击响应 (FIR)滤波器和最小均方 (L MS)算法 ,可以提高管道压力。

Some difficulties exist in the signal processing of the leak detection of pipeline that is caused by the low signal to noise ratio.It is possible to enhance signal to noise ratio for pressure and flow signals by means of the adaptive filtering.The adaptive filter presented here is based in FIR(Finite Impulse Response) filtering with delay structure and combined with LMS (Least Mean Square) algorithm.The test results show the applicability and effectiveness for this approach.
