基于GPRS无线远程监控系统的关键技术研究

南京邮电大学硕士研究生学位论文摘要I摘要近年来，作为国内外研究的热点课题，物联网技术备受关注。中国在物联网领域开展了大量的理论及应用研究，并且取得了长足进步。作为物联网的典型应用，远程监控技术面临着新的机遇与挑战。本文提出了一种新型的基于GPRS的无线远程监控系统。系统采用“监测节点—监测中心”结构，监测节点集成了D203S热释电红外传感器、SHT10温湿度传感器、TSL2561光照度传感器以及GXT-Y601图像传感器。根据系统性能需求，选用基于传感器技术的Atmega128+TR800系统方案，以Atmega128单片机作为主控制器，TR800作为无线传输模块。数据上传采用数据包直接转发解决方案，按照Xmodem协议格式上传至TR800无线模块并使用AT命令通过短彩信方式发送到手机终端。本系统有效实现了监测环境内入侵检测、数据采集以及警情处理等功能，具有投入成本低、数据可靠性好等优势。文章详细论述了各模块的软硬件设计，着重于各模块硬件电路的设计与实现、系统功能模块的详细说明以及软件上的实现流程。根据系统测试需要，搭建了软硬件实验平台。在VisualC++6.0平台上利用MSComm通信控件编写了模块调试程序，并使用串口调试工具对系统进行了软硬件调试。最后对系统进行了性能测试，并根据测试结果，对系统的响应时间、实时性、可靠性做了详尽的分析。实验验证了基于传感器技术的Atmega128+TR800系统方案的可行性以及数据上传采用数据包直接转发方案的有效性。本系统方案对物联网中智能手机监控系统的进一步研究具有一定的借鉴意义。关键字：远程监控；GPRS；多媒体信息服务；Atmega128南京邮电大学硕士研究生学位论文AbstractIIAbstractInrecentyears,asthedomesticandinternationalresearchhotspot,Internetofthingstechnologygetsgreatattention.InthefieldofInternetofthings，Chinahasstartedalargenumberoftheoreticalandappliedresearch,andhasmadegreatprogress.Asthecontentofnetworkapplications,remotemonitoringtechnologyisfacingnewopportunitiesandchallenges.ThisthesispresentsanewwirelessremotemonitoringsystembasedonGPRS.Thissystemadopts“monitoringnodeandmonitoringcenter”structure.ThemonitoringnodeintegratesD203Spyroelectricinfraredsensor,SHT10temperatureandhumiditysensor,TSL2561illuminancesensorandGXT-Y601imagesensor.Accordingtotheperformancerequirements,thissystemusesthearchitectureofAtmega128+TR800basedonsensortechnologywithAtmega128MCUasthemaincontrollerandTR800asthewirelesstransmissionmodule.Environmentaldatausesthedatapacketforwardingsolution,inaccordancewiththeXmodemprotocolformatuploadingthedatatoTR800wirelessmoduleandusingtheATcommandviaMMStosendtothemobilephoneterminal.Itcanefficientlydetecttheintrusion,collectthedataandprocessthealarmwiththeadvantagesoflowinvestment,goodreliability.Thisthesisdiscussesthemainmodulesofthehardwareandsoftwaredesignindetail,focusingoneachmodulehardwarecircuitdesignandimplementation,thesystemfunctionmoduledetaileddescriptionandsoftwarerealizationprocess.Inalaboratoryenvironment,WebuildthehardwareplatformanduseVC++6.0topreparetheplatformtestsoftware.What’smore,Wehavemadetheexhaustivetestandanalysisofthesystemresponsetime,real-time,reliability,whichprovesthefeasibilityandvalidityofthissystem.Thisschemehascertainreferencesignificancetothefurtherstudyoftheintelligentmobilephonemonitoringsystem.Keywords:Remotemonitoring;GPRS;MMS;Atmega128南京邮电大学硕士研究生学位论文目录III目录摘要.............................................................................................................................................IAbstract.........................................................................................................................................II目录..........................................................................................................................................III第一章绪论................................................................................................................................11.1课题背景及发展现状.....................................................................................................11.1.1课题背景.............................................................................................................11.1.2国内外发展现状..................................................................................................21.1.3发展趋势.............................................................................................................31.2论文研究内容和章节安排...............................................................................................5第二章系统分析及总体方案.....................................................................................................62.1系统分析.........................................................................................................................62.1.1系统功能需求.....................................................................................................62.1.2系统性能要求.....................................................................................................72.2系统总体方案.................................................................................................................82.2.1系统架构方案.....................................................................................................82.2.2系统总体结构.....................................................................................................92.2.3监控节点方案...................................................................................................102.2.4无线传输方案...................................................................................................122.2.5需要解决的关键问题........................................................................................132.3系统主要特点及应用....................................................................................................132.4本章小节........................................................................................................................15第三章系统硬件总体设计................................................
