基于gpsgprs車載圖像監(jiān)控系統(tǒng)的設(shè)計(jì)_本科畢業(yè)設(shè)計(jì)40設(shè)計(jì)41

1、本科畢業(yè)論文(設(shè)計(jì))1基于GPSGPRS車載圖像監(jiān)控系統(tǒng)的設(shè)計(jì)摘要隨著嵌入式應(yīng)用技術(shù)和無線網(wǎng)絡(luò)技術(shù)的快速發(fā)展，結(jié)合了GPS定位技術(shù)和GPRS無線通信技術(shù)的嵌入式GPS車載監(jiān)控系統(tǒng)應(yīng)運(yùn)而生。論文將USB視頻采集技術(shù)引入到車載終端監(jiān)控系統(tǒng)中，提出了一種車載監(jiān)控和圖像傳輸系統(tǒng)的具體實(shí)現(xiàn)方案。論文首先對(duì)車載監(jiān)控相關(guān)的GPS定位技術(shù)、GPRS無線網(wǎng)絡(luò)技術(shù)及USB接口技術(shù)做了詳細(xì)介紹。然后是對(duì)車載監(jiān)控終端硬件方案的設(shè)計(jì)與實(shí)現(xiàn)給出了具體的實(shí)現(xiàn)框圖。最

2、后對(duì)系統(tǒng)中所用到的主控制模塊S3C2410X處理器、GPS模塊及GPRS通訊模塊等作了詳細(xì)的介紹。為減少GPRS網(wǎng)絡(luò)傳輸?shù)臄?shù)據(jù)量，在圖像采集模塊中采用了JPEG軟件壓縮編碼技術(shù)，對(duì)靜態(tài)圖像進(jìn)行壓縮編碼，較大地節(jié)省了網(wǎng)絡(luò)資源，提高了圖片的傳輸速度。論文的最后總結(jié)了所完成的工作，給出了設(shè)計(jì)的不足之處和有待完善的地方?；贕PSGPRS的車載圖像監(jiān)控終端最終可以實(shí)現(xiàn)GPS定位數(shù)據(jù)和圖像數(shù)據(jù)的采集與上傳功能。利用這些信息，監(jiān)控中心可實(shí)時(shí)跟蹤車輛

3、并及時(shí)獲取車內(nèi)信息，該方案充分利用了S3C2410X處理器資源，方便且實(shí)用地實(shí)現(xiàn)了低成本的車輛監(jiān)控功能。關(guān)鍵詞：GPS定位技術(shù)，GPRS通信技術(shù)，車載監(jiān)控終端，圖像采集本科畢業(yè)論文(設(shè)計(jì))3devicesimageacquisition目錄第一章緒論...............................................................................................
