精品文档---下载后可任意编辑摘 要管道运输以其独特的安全优势和成本优势，已广泛应用于城市生活和工业生产的自来水输送系统、污水排放系统、煤气或天然气输送系统及工业石油输送系统等。随着管道运输的进展，管道运输已成为一个独立的交通运输部门——管道运输业。它是国民经济综合运输的重要组成部分之一。管道运输在国民经济中的影响也日趋扩大，尤其是石油管道运输。因而石油管道运输的安全稳定则成为一项极具现实意义的重要问题。本文的主要工作体现在以下几个方面：首先，本文简要地介绍了管道运输的概况，对国内外管道运输的进展历史、现今状况以及未来的进展做了简单的介绍；还详细地分类介绍了目前管道泄漏检测的常见方法，从它们的原理、特点及应用角度等方面做了细致的分析和归类。其次，本文针对我国流体管道运输的特点，详细地介绍了基于负压波的管道泄漏检测定位方法；讨论了基于小波的泄露检测方法；同时，还探讨了如何在多种检测方法并存的方式下，进行冲突消解。关键词：泄露检测；负压波；小波变换；定位算法精品文档---下载后可任意编辑Based on Wavelet Pipe Pressure Detection AlgorithmsAbstractBecause of its unique security advantages and cost advantages, pipeline transportation is used inwater supply system, sewage disposal system, natural gas transport system and industrial oil transport system for the city life and industry manufacture.Pipeline transportation has become a separate traffic transport section—pipeline carrying tradewith the development of pipeline transport.It is one of the important parts of State Economy Integration Transportation. Pipeline transportation is growing influentially, particularin the oil pipeline transport. And it has become more and more important to the pipeline transportation whether the pipeline transport can run safely and steadily.The main efforts accomplished can be summed up as the following aspects:First, the history and the current situation of the pipeline transportare briefly introduced, and itsfuture developmentis also forecasted. After the usual de...
