学生公寓电量监控系统的设计和实现 电气工程管理专业VIP免费

摘要随着信息技术的发展与快速应用，用电管理也快速步入了信息化的轨道。为弥补现有公寓用电管理系统在功能上、结构上的缺陷，着重考虑用电管理系统在安全监控等功能以及系统结构上的改进，强化系统终端功能。本文分析国内宿舍集体用电管理的发展趋势，结合现有条件，针对目前宿舍供电网络中自动化水平低，故障率高等现状而设计。提出一种智能电网下的宿舍用电监控解决方案。该系统以单片机AT89S52为控制核心，把得到的数字量送入单片机进行数据处理，然后通过LCD液晶显示电压和电流，功率等的实时值。集成了SPI串行总线和模拟、数字功能模块，简化了外围电路设计。能够实现对电网运行状态实时监测、远程控制高压熔断器的断开与闭合、电能计量以及对历史用电状况进行分析等。与传统设计相比，系统避免了布线的烦恼，使宿舍看起来更加整洁干净。同时模块化的设计，系统的维护更加方便，扩展性加强，适用于管理集体化的宿舍。关键词：安全用电；单片机；用电监控AbstractWiththedevelopmentandrapidapplicationofinformationtechnology，powermanagementhasalsosteppedintotheinformationtrackrapidly.Inordertomakeupforthefunctionalandstructuraldefectsofthecurrentapartmentelectricmanagementsystem，itemphasizestheimprovementofthepowermanagementsysteminsecuritymonitoringandsoonandthestructureofthesystem，andstrengthenstheterminalfunctionofthesystem.Thispaperanalyzesthedevelopmenttrendofcollectiveelectricitymanagementindomesticdormitories，andcombinestheexistingconditionstodesignthecurrentsituationoflowautomationlevelandhighfailurerateinthecurrentdormitorypowersupplynetwork.Amonitoringsolutionfordormitorypowerconsumptionundersmartgridisproposed.ThesystemtakestheMCUAT89S52asthecontrolcore，andsendsthedigitalamounttothesinglechipcomputerfordataprocessing，andthendisplaystherealtimevalueofthevoltageandcurrent，thepowerandsoonthroughtheLCDliquidcrystal.SPIserialbusandanaloganddigitalfunctionmodulesareintegrated，whichsimplifiesthedesignofperipheralcircuits.Itcanrealizereal-timemonitoringoftheoperationstateofthepowergrid，remotecontrolthedisconnectionandclosureofhighvoltagefuse，electricenergymeasurementandtheanalysisofthehistoricalelectricityuse.Comparedwithtraditionaldesign，thesystemavoidsthetroubleofwiringandmakesthedormitorieslookmoreneatandclean.Atthesametime，modulardesign，systemmaintenanceismoreconvenient，expansibilityisenhanced，andissuitableformanagingcollectivizeddormitories.Keywords:safepowerconsumption，singlechipmicrocomputer，powerconsumptionmonitoring.目录摘要...............................................................................................................................IAbstract.......................................................................................................................II第一章前言..............................................................................................................11.1研究背景...........................................................................................................11.2研究意义...........................................................................................................11.3智能用电系统的总体方案...............................................................................1第二章电量监控系统的硬件设计..................................................................12.1硬件电路...........................................................................................................12.1.1单片机最小系统模块...................................................
