摘要面对快速发展的电力系统,我国对于查出故障专用的故障录波器的要求也日益增高,以便应对各种的情况,行业对故障录波器功能需求更高,需要能够更快更准确的找出故障发生的地方,与传统的故障录波器在各个方面遇到的问题,我们设计一款能大大提升性能的故障录波,因此本文设计ARM和DSP双芯片设计的故障录波器,连接上位机可以远程监控和分析。本文首先介绍了故障录波器现如今的国内外现状和使用情况,根据国内的故障录波器使用现状和与国内的故障录波器相比较,设计了适合国内现状使用的双芯片故障录波器。DSP芯片用于采集数据,经过查验采样电路收集的数据,进行处理,再将得到的处理数据与阈值对比,依次来判断故障。通过直接控制平台选用ARM处理器,将DSP得到的数据进行处理,最后将数据传送给远程的上位机软件,进行数据分析和实时监控。因为本论文使用的是DSP和ARM芯片同时工作,为了保证DSP数据采集和ARM系统之间的快速、有效的数据交换,我们采样的我们在采样过程中使用的HPI技术,就是利用了在两个核心之间进行命令控制和高速数据通讯,以此到达快速、有效的目的。在论文最后还使用了VB设计了上位机程序,使其可以远程监控和数据分析。关键词:故障录波器,DSP,上位机AbstractWiththerapiddevelopmentofourcountry'spowersystembusiness,therequirementsforfaultrecorderarehigher,andthefunctionalrequirementsarehigher.Weneedtobeabletofindoutthefaultlocationmorequicklyandaccurately.Comparedwiththetraditionalfaultrecorder,wedesignafaultrecorderthatcangreatlyimprovetheperformance,Therefore,thispaperdesignsafaultrecorderbasedonarmandDSP,whichcanbeconnectedtothehostcomputerforremotemonitoringandanalysis.Thispaperfirstintroducesthecurrentsituationandapplicationoffaultrecorderathomeandabroad.Accordingtothecurrentsituationofdomesticfaultrecorderandthecomparisonwithdomesticfaultrecorder,adualchipfaultrecordersuitablefordomesticuseisdesigned.TheDSPchipisusedtocollectdata,whichiscollectedandprocessedbythesamplingcircuit.Theresultiscomparedwiththethresholdvaluetorealizefaultidentification.ThecontrolplatformselectsARMprocessortoprocessthedatafromDSP,andfinallytransmitsthedatatotheremotePCsoftwarefordataanalysisandreal-timemonitoring.BecausethispaperusesDSPandarmchipstoworkatthesametime,inordertoensurethefastandeffectivedataexchangebetweenDSPdataacquisitionandarmsystem,weuseHPItechnologytorealizethecommandcontrolandhigh-speeddatacommunicationbetweendualcores.Finally,theuppercomputerprogramisdesignedbyusingVB,whichcanbeusedforremotemonitoringanddataanalysis.Keywords:faultrecorder,DSP,hostcompute目录1绪论............................................41.1本课题研究的背景和意义..........................................................................41.2研究现状.................................................................................................61.2.1国内研究现状..................................................................................61.2.2国外研究现状..................................................................................71.3经济型与安全性分析..................................................................................81.4论文的主要研究内容..................................................................................91.5论文工作的主要内容..................................................................................92.嵌入式故障录波器总体设计方案....................92.1设计思路.................................................................................................92.2故障录波器的基本要求...........................................
