XX大学毕业设计（论文）I基于单片机的远程监控系统的终端设计摘要电梯作为一种常用的垂直交通工具，伴随着城市的发展而迅速增加，其应用是日益广泛的。然而每个电梯运行状况的好坏会直接影响城市居民的生活质量和工作效率，同时更是影响着城市经济的可持续发展和人民生命安全，因此就产生了对电梯设备进行远程监控的要求。凭借监控系统来获得关于电梯系统的实时运行状况信息，可以防止电梯溜梯、困人、冲顶、蹲底、过载等情况突发时不能及时排除故障而带来更多无法预知的灾难。显然，传统的相对落后的监控手段（电梯工人的巡检）早已跟不上城市发展的步伐。近些年来，随着单片机技术和自动控制理论的迅速发展，基于单片机的远程监控已经成为电梯发展的必然趋势。因此，研究及开发基于单片机的多电梯远程监控系统具有一定的意义。本文首先对国内、外的远程监控系统相关理论进行了深入的研究，并在分析和研究电梯远程监控系统基础之上，提出了本文要研究的主要内容，即设计了一种以AT89C51为架构的多电梯远程监控系统，该系统可以实现远程现场的实时监控及数据的采集，并且在监测和显示电梯运行状态的各种参数的同时，可以实现远程登录和监控。基于单片机的多电梯远程监控系统，主要是用来监控电梯的运行情况，根据电梯发出的信号，及时的做出反应，并进行相应的处理。根据系统需要，所运用到的外围电路主要包括电源模块、温度电路模块、报警电路模块、视屏采集模块、RS-485通信模块和LCD显示模块，再根据有关单片机和数据采集传输方面的知识，利用C语言编程，完成远程监控的设计。我认为在未来，电梯系统会是向智能化方向发展的，主要有以下特征：以人为本的通用化设计理念，统一化设计的趋势，应付突发性灾难的能力。关键词：多电梯；远程监控；数据采集；LCD显示模块XX：基于单片机的远程监控系统的终端设计IIMicrocontroller-basedremotemonitoringsystemterminaldesignAbstractAsacommonverticallifttransport,alongwiththerapidincreaseinthecity'sdevelopment,itsapplicationisbecomingwidespread.However,thestatusofeachelevatoroperationwilldirectlyaffectthequalityoflifeofurbanresidentsandworkefficiency,butalsoaffectthesustainabledevelopmentofthecity'seconomyandpeople'slives,andthereforecreatedademandforelevatorequipmentforremotemonitoringrequirements.Withtheelevatorcontrolsystemtoobtaininformationaboutthereal-timeoperationalstatusinformation,youcanpreventtheelevatorslipladder,trappedpeople,hoisting,etc.suddenendsquattingcannottimelytroubleshootingandbringmoreunpredictabledisaster.Obviously,thetraditionalmeansofmonitoringtherelativebackwardness(elevatorworkerspatrol)alreadycannotkeepupthepaceofurbandevelopment.Inrecentyears,withthechiptechnologyandtherapiddevelopmentofautomaticcontroltheory,Microcontroller-basedremotemonitoringhasbecomeaninevitabletrendofdevelopmentelevator.Therefore,theresearchanddevelopmentofmicrocontroller-basedmulti-elevatorremotemonitoringsystemhasacertainsignificance.Firstly,thedomesticandforeignremotemonitoringsystemrelatedtheoriesin-depthresearchandanalysisandresearchelevatorremotemonitoringsystembasedontheproposedmaincontentofthispapertostudy,namelyAT89C51forthedesignofaframeworkMultielevatorremotemonitoringsystem,thesystemcanachievereal-timemonitoringandremotesitedatacollection,andinthemonitoringanddisplayrunningtheelevatoratthesametimethevariousparameters,youcanachieveremoteloginandmonitoring.Microcontroller-basedmulti-elevatorremotemonitoringsystemismainlyusedtomonitortheoperationoftheelevator,theelevatorsignals,timelyresponse,andmaketheappropriatetreatment.Accordingtothesystem,asappliedtotheperipheralcircuitincludesapowersupplymodule,thetemperaturecircuitmodule,thealarmcircuitmodule,screencapturemodule,RS-485communicationmoduleandLCDdisplaymodule,accordingtotheSCManddataacquisitionandtransmissionofknowledge,theuseofCprogramminglanguage,completeremotemonitoringdesign.Ithinkinthefuture,theelevatorsystemistoprovideintelligentdirection,mainlyhasthefollowingcharacteristics:people-orienteduniversaldesignconcept,unifieddesigntrends,theabilitytodealwithunexpecteddisasters.Keywords:multipleelevators;remotemonitoring;datacollection;LCDdisplaymoduleXX大学毕业设计（论文）III目录引言........................................................................................................................................1第1章绪论..............................................................................................................................21.1国内外研究现状.................................................................................................................21.1.1国内外现状及存在问题..................................................................................................21.1.2目前电梯监控系统的分类..............................................................................................31.1.3多电梯远程监控系统的发展趋势..................................................................................41.2课题的研究意义和内容.....................................................................................................41.2.1课题的研究意义..............................................................................................................41.2.2课题研究的内容..............................................................................................................4第2章多电梯远程监控系统结构概述..................................................................................62.1远程监控系统整体结构设计及实现功能.........................................................................62.1.1远程监控系统整体架构..................................................................................................62.1.2功能概述..........................................................................................................................72.2远程监控系统设计概述.....................................................................................................82.2.1硬件设计概要..................................................................................................................82.2.2软件设计概要..................................................................................................................9第3章多电梯数据终端控制器的硬件设计........................
