毕业论文基于3G的家庭远程视频监控系统的研究与设计基于3G的家庭远程视频监控系统的研究与设计摘要随着科技的发展和人们安全意识的提高，远程监控系统得到越来越广泛的应用，但是以往的远程监控由于硬件结构、网络结构的复杂性及传输速率的限制，使之在技术上和成本上形成瓶颈，不适合用于家庭远程监控。近年来发展迅速的3G移动通信技术和3G网络建设以及智能监控技术提供了解决这一问题的有效途径。本文主要介绍基于TMS320DM642和3G无线数据模块的家庭远程视频监控系统的设计与实现。该系统以高性能DSP芯片TMS320DM642为核心，包括视频采集模块、和无线传输模块以及备份模块，可以同时采集三路视频和多路现场设备工作信息，并对实时情形进行运动检测，然后对视频进行MPEG-4编码，由DTM6211无线收发模块通过3G网络发送给远端3G终端手机，实现实时监控。本文还给出了一些视频驱动方法并探究了运动检测的算法问题。还对TMS320DM642与DTM6211之间的通信问题进行了详细阐述。另外，因为本文的目的是探讨一种家庭监控系统的设计方案，最终目的是为了推向实用端，故在具体设计中始终注意了整个系统的成本问题，力求在系统的设计中就能够为以后的实际应用打下坚实基础。本文最后对全文做了总结，讨论了一些需要继续深化和改进的地方，并提出了相应的改进办法。关键词：家庭监控，远程视频监控，3G，运动检测，DSP3G-basedfamilyofRemoteVideoSurveillanceSystemResearchandDesignAuthor：LeiLuTutor：FengwenWangAbstractWiththedevelopmentofscienceandtechnologyandpeople'ssafetyawareness,remotemonitoringsurveillancesystemhasbeenincreasinglywidelyused,butthepastisbecausethehardwarestructureofremotemonitoringaswellasmorecomplexnetworkstructure,thecostisoftencausedbyabottleneck,notsuitableforRMONfamily.Inrecentyearstherapiddevelopmentof3Gnetworksandintelligentmonitoringtechnologytosolvethisproblemprovidedthetechnicalsupport.Inthispaper,basedontheTMS320DM642and3GwirelessdatamodulescomprehensivemonitoringsystemofthefamilyoftheDesignandImplementation.MonitoringSystemDesignandImplementation.ThesystemTMS320DM642chipforhigh-performanceDSPcore,includingthevideocapturemodule,RS485busmodules,andwirelesstransmissionmoduleandbackupmodule.Canbecollectedatthesametimethree-wayvideoandmulti-channelinformationontheworkoffielddevices,andmotiondetectionforreal-timesituation,andthenontheMPEG-4videoencoding,throughthewirelesstransceivermoduleDTM6211senttotheremoteend3Gmobilephones,real-timemonitoring.Inthispaper,thengivenanumber-drivenapproachandexplorestheissueofmotiondetectionalgorithms.TMS320DM642andDTM6211alsocommunicationbetweentheissuesindetail.Finally,thefulltextofthisarticlesummarizedanddiscussedsomeoftheneedtocontinuetodeepenandimprovetheplace,andthecorrespondingmeasuresforimprovement.Keywords:Homemonitoring,MotionDetection,DSP,3G，RemoteVideoMonitoring目录1绪论.............................................................11.1监控系统的发展过程.......................................................................................11.2无线传输技术的发展.......................................................................................21.3国内外相关研究的现状及分析.......................................................................31.3.1监控系统的发展现状............................................................................31.3.2国内外家庭监控的发展状况................................................................41.4项目提出和论文的结构安排...........................................................................72系统总体介绍.....................................................82.1系统总体设计...................................................................................................82.1.1现有监控系统结构的分析比较............................................................82.1.2系统总体结构........................................................................................92.2无线通讯实施方案.........................................................................................102.2.1无线通讯方式的比较..........................................................................102.2.23G网络平台的使用.............................................................................112.3系统主要特点及创新点..................................................................................113监控前端平台设计................................................133.1DSP智能处理模块........................................................................................133.1.1系统主控芯片的选取..........................................................................133.1.2DM642简介.........................................................................................133.2视频采集模块.................................................................................................153.3RS485模块.....................................................................................................163.4McBSP模块...................................................................................................173.4.1McBSP简介.........................................................................................173.4.2采用McBSP实现串口通讯................................................................183.53G无线数据传输模块...................................................................................193.6其余模块设计.................................................................................................203.6.1备份模块..............................................................................................203.6.23G终端接收模块................................................................................214系统软件实现及相关算法研究......................................234.1视频驱动程序.................................................................................................234.2DM642与DTM6211的通讯........................................................................244.2.1McBSP的配置.................................................................
