基于小波分析的输油管道泄漏点定位研究

摘要

The use of wavelet wave method in oil pipelines was investigated, and the basic principle of detecting pressure wave and wavelet denoise Technology were gained, the accuracy of leak point location can be gained, while analysis the featured inflection point of pressure wave by using he wavelet wave method. Emulation analysis shows wavelet wave is an effectiveness method to locate the leakage.%将小波分析方法应用在输油管道的泄漏点检测中,分析了压力波监测基本原理和小波消噪的基本原理；使用小波分析对泄漏时压力波突降点进行捕捉分析,进而确定管道泄漏点的准确位置.分析结果表明,小波分析可以有效地定位泄漏点.
