五邑大学本科毕业设计摘要电表表示着人们日常用电的多少，现在每家每户安装的基本上是带有转盘的那种电表它只能显示出用电总量。若想查看上个月的用电量，只能靠电费单计算得来。现在已经是信息时代了，这种做法很显然跟不上社会潮流。近几年来，社会提倡低碳、绿色经济和可持续发展，在这种思想的推动下，智能电表将会成为社会的潮流。智能电表是在传统电表的基础上增加了自动化和智能化的功能，从而进一步提高电网的效率、提高供电的可靠性、电能的质量并且完善用电户的服务，从而更好适应电力市场。现在智能电网是全球电力部门研究和讨论的热点话题，智能电表是智能电网中的最重要的环节，它支撑着电网的信息化、自动化以及互动化等方面的实现。微处理器是智能电表的最主要的核心器件。它可以储存海量的检测数据，同时对测量出的结果进行分析、判断和处理。本次设计是运用单片机STC89C52为微处理器、CS5460A芯片进行电能测量和计算、X5045芯片作为外部存储、数码管进行显示进行设计的。关键词智能电表；自动化；C51单片机；CS5460AI五邑大学本科毕业设计AbstractElectricitymetermeansthenumberofpeopleeverydayelectricity,andnoweveryhouseholdisbasicallyequippedwiththekindofmeter,whichcanonlyshowthetotalamountofelectricity.Toseethepowerconsumptionlastmonth,onlybyelectricitysinglecalculated.Itisnowtheinformationage,andthisapproachisclearlynotsocialtrends.Inrecentyears,thesocialpromotionoflow-carbon,greeneconomyandsustainabledevelopment,inthepromotionofthisidea,smartmeterwillbecomethetrendofthesociety.Smartmeterisautomaticandintelligentfunctionisaddedonthebasisoftraditionalmeter,energyefficiencysoastofurtherimprovethepowergrid,improvepowersupplyreliability,powerqualityandperfectserviceoftheusers,inordertobetteradapttothepowermarket.Nowthesmartgridisahottopicintheglobalpowersectorresearchanddiscussion,thesmartmeteristhemostimportantpartofsmartgrid,whichsupporttherealizationofgridinformationization,automationandinteractionof.Themicroprocessoristhemostimportantcoredeviceofthesmartmeter..Itcanstorevastamountsofdetectiondataandanalyze,judgeandprocesstheresultsofthemeasurement..Thisdesignistheuseofsingle-chipmicrocomputerSTC89C52andCS5460Achipforpowermeasurementandcalculation,X5045chipastheexternalstorage,digitaltubedisplaydesign.KeywordsSmartmeterAutomation51MCUS5460AII五邑大学本科毕业设计目录摘要..............................................................................................................................................IABSTRACT...................................................................................................................................II第1章绪论....................................................................................................................................11.1智能电表的概念...............................................................................................................11.2智能电表的发展背景.......................................................................................................11.3智能电表的结构...............................................................................................................21.4智能电表的主要特点.......................................................................................................2第2章主要芯片的介绍................................................................................................................42.1微控制器STC89C51单片机...........................................................................................42....
