基于gpsgprs车载图像监控系统的设计论文(设计)学士学位论文.doc

本科毕业论文(设计)28基于GPS/GPRS车载图像监控系统的设计摘要随着嵌入式应用技术和无线网络技术的快速发展，结合了GPS定位技术和GPRS无线通信技术的嵌入式GPS车载监控系统应运而生。论文将USB视频采集技术引入到车载终端监控系统中，提出了一种车载监控和图像传输系统的具体实现方案。论文首先对车载监控相关的GPS定位技术、GPRS无线网络技术及USB接口技术做了详细介绍。然后是对车载监控终端硬件方案的设计与实现,给出了具体的实现框图。最后对系统中所用到的主控制模块S3C2410X处理器、GPS模块及GPRS通讯模块等作了详细的介绍。为减少GPRS网络传输的数据量，在图像采集模块中采用了JPEG软件压缩编码技术，对静态图像进行压缩编码，较大地节省了网络资源，提高了图片的传输速度。论文的最后总结了所完成的工作，给出了设计的不足之处和有待完善的地方。基于GPS/GPRS的车载图像监控终端最终可以实现GPS定位数据和图像数据的采集与上传功能。利用这些信息，监控中心可实时跟踪车辆并及时获取车内信息，该方案充分利用了S3C2410X处理器资源，方便且实用地实现了低成本的车辆监控功能。关键词：GPS定位技术，GPRS通信技术，车载监控终端，图像采集CarriestheimagemonitorterminalbasedonTheGPS/GPRSvehiclethedesignAuthor:LiBaohaiTutor:ZhaoYanjieABSTRACTWiththerapiddevelopmentoftheembedded-applicationsandwirelessnetworktechnology,theembeddedvehiclemonitoringsystemwhichcombinestheGPSlocationtechnologyandGPRSwirelesscommunicationtechnologycomesintobeing.Inordertomeettherequirement,thepaperintroducesUSBvideocapturetechnologyintoembeddedvehiclemonitoringterminalandputsforwardanewsolution.Firstly,thepaperdescribestheGPStechnology,GPRSwirelessnetworktechnologyandUSBinterfacetechnologyindetail.Secondly,thepaperexplainshowtocarryoutthehardwaredesign.Giveaspecificrealizationofblockdiagram.ThelastintroducethemaincontrolmoduleS3C2410Xprocessor,GPSmoduleandGPRScommunicationmoduleusedinthesystem.InordertoreducethequantityofdatatransmittedbytheGPRSnetwork,JPEGcompressiontechnologywasusedtocompressstaticimageintheimageacquisitionmodule,whichcouldeconomizethenetworkresourcesandspeeduptheimagetransmission.Finally,thepapersummariesalltheworksandgivesthemethodsforfurtherimprovement.TheembeddedvehicleimagemonitoringterminalwhichusesGPS/GPRStechnologycouldcollecttheGPSandpictureinformationabouttheautomobileandsendittothemonitoringcenter.Makinguseoftheinformation,monitoringcenterstrengthensitssupervisionabilitytotrackautomobile,ThedesignmakesfulluseofresourcesonARMS3C2410Xprocessorandimplementsvehiclemonitoringfunctionsatalow-costbutmoreconveniently.Keywords：GPSpositioningtechnology,GPRScommunicationstechnology,vehicl
