1、基于小波的管道压力检测算法研究基于小波的管道压力检测算法研究管道运输以其独特的安全优势和成木优势，已广泛应用于城市生活和工业生产的口來水输送系统、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。随着管道运输的发展，管道运输己成为一个独立的交通运输部门一一管道运输业。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□趋扩人，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。木文的主耍工作体现在以卜•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发展历史、现今状况以及未来的发展做了

2、简单的介绍;还详细地分类介绍了FI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；研究了基于小波的泄霜检测方法；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BasedonWaveletPipePressureDetectionAlgorithmsAbstractBecauseofitsuniquesecurityadvantagesandcostadvantages,pipeli
