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。随着管道运输的发展，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发展历史、现今状况以及未来的发展做了简单的介绍；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；研究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BasedonWaveletPipePressureDetectionAlgorithmsAbstractBecauseofitsuniquesecurityadvantagesandcostadvantages,pipelinetransportationisusedinwatersupplysystem,sewagedisposalsystem,naturalgastransportsystemandindustrialoiltransportsystemforthecitylifeandindustrymanufacture.Pipelinetransportationhasbecomeaseparatetraffictransportsection—pipelinecarryingtradewiththedevelopmentofpipelinetransport.ItisoneoftheimportantpartsofStateEconomyIntegrationTransportation.Pipelinetransportationisgrowinginfluentially,particularintheoilpipelinetransport.Andithasbecomemoreandmoreimportanttothepipelinetransportationwhetherthepipelinetransportcanrunsafelyandsteadily.Themaineffortsaccomplishedcanbesummedupasthefollowingaspects:First,thehistoryandthecurrentsituationofthepipelinetransportarebrieflyintroduced,anditsfuturedevelopmentisalsoforecasted.Aftertheusualdetectionmethodselaborated,thesemethodsareanalyzedandclassifiedbasedontheirtheory,characteristic,application,andsoon.Then,aimingatthecurrentsituationofourcountry’sliquidtransportpipelines,aleakdetectionandlocationmethodbasedonsuctionwavetheoryisintroduced;anddetectingtheleaklocationusingwavelettheory.Itisalsoresearchedtoprocesstheconflictbyusingmultiarithmetic.Giveacommonmethodforconflictresolution.Thisthesisalsobringforwardtheconceptofthealgorithmfactorybymethodofleakdetectionsystemdesignschemebasedontheinnovationandwavelettransformdetection.Thismakesthesystemextensibleandgivesthedesignmethodallowsthesystemnotonlyinthefunctionalextensibility,butalsointheextensibilityofdetectionsignals.Keywords:leakdetection,wavelettrans
