| 摘 要： | 泄漏检测在油料长输管道安全生产中占有重要的位置。本文以MATLAB6．5小波函数为分析工具，以泄漏点产生的负压波“拐点”为对象，以确定泄漏点的相对位置为目的，先后进行小波分析工具的理论介绍，并在消噪、两类奇异点检测等应用方面进行分析。文章结合生产现场的应用，对实际数据进行重要分析与应用，并总结了小波分析在泄漏定位上的一些经验。

| Abstract: | The examination of leakage of the oil pipeline in safe operation is in the important position. This article takes the MATLAB6.5 wavelet function as the analysis tool, takes the inflection point of the negative pressure wave due to the leakage as the object, and takes the determination of the relative position of the leakage point as the goal. The content includes the theory of wavelet analysis tool, the analysis of signal noise elimination and two kinds of singular points examination. With the adoption in production process, the important analysis and the application of the actual data are implemented. From that we summarized some experiences of the wavelet analysis about the leakage location of oil pipeline. |
