摘要

隨著我國(guó)經(jīng)濟(jì)的迅速發(fā)展,過人消費(fèi)水平也呈現(xiàn)了飛速增長(zhǎng),汽車的數(shù)量也隨著迅速增加,我國(guó)GPS車輛定位系統(tǒng)市場(chǎng)現(xiàn)在已經(jīng)進(jìn)入規(guī)模發(fā)展時(shí)期,本文對(duì)GPS汽車定位系統(tǒng)運(yùn)用到的技術(shù)理論基礎(chǔ)作出了詳細(xì)的介紹,兵非別提供了GPS定位車載終端的硬件和軟件的具體設(shè)計(jì)方案.
GPS即全球系統(tǒng)定位,它是一個(gè)中距離圓形軌道衛(wèi)星定位,可以為地球表面絕大部分地區(qū)提供準(zhǔn)確的定位和高精度的時(shí)間基準(zhǔn).GPRS是在GSM的系統(tǒng)基礎(chǔ)上引入新的部件而構(gòu)成的無(wú)線數(shù)據(jù)出傳輸系統(tǒng).它的基本功能是在移動(dòng)終端,GPRS網(wǎng)內(nèi)以及和Internet網(wǎng)絡(luò)的路由器之間傳輸分組數(shù)據(jù),根據(jù)現(xiàn)代智能交通系統(tǒng)的實(shí)際需求,本文設(shè)計(jì)了一種基于GPRS的車載衛(wèi)星定位系統(tǒng),系統(tǒng)采用單片機(jī)作為處理器,通過GPRS網(wǎng)絡(luò)建立無(wú)線通信鏈路,把車載移動(dòng)終端的GPS定位信息傳到Internet網(wǎng)上的服務(wù)器,實(shí)現(xiàn)在線實(shí)時(shí)檢測(cè)車輛行駛各類信息,實(shí)現(xiàn)了控制中心實(shí)時(shí)檢測(cè)車輛行駛狀態(tài),完成了車輛定位的目的

ABSTRACT
As China’s rapid economic development people also rapid consumptiom growth in the number of vehicles has increased as rapidly. GPS vehicle location system in China has now entered the scale of the market development period this article on the use of GPS vehicle positioning system technology theroy to make a detailed on the use of GPS vehicle positioning system technology theory to make a detailed introduction, and each vehicle terminal provides GPS positioning of specific hardware and software design.
GPS or global positioning system it is a middle-distance circular orbit satellite positioning system most parts of the earth’s surface can provide accurate positioning and high precision time base. GPRS in the GSM system is based on the introduction of new components which consititute the wireless data transmission system。Its basic function is in the mobile terminal。GPRS networds and Internet networks within and between the router packet data transmission According to the actual modern intelligent transportation systems this paper designs a GPRS-based vehicle positioning system he system uses single chip as the processor through the GPRS network to establish wireless communication link the mobile terminal’s GPS location infornmation transmitted online Internet server to achieve real-time monitoring online traffic infornmation of all types to achieves a real-time monitoring traffic control center in the state completed a vehicle positioning purposes.
