【正文】 ded from the original mechanical mode to the latest GSM/GPS based work mode after several generations. But in China, considering the price and technology, the mon electronic vehicle alarm equipments are still the dominant ones.In view of the deficiencies of most mon vehicle alarm equipments prevalent in the market， such as single alarm ability, low security and lack of tracking and monitoring ability, but this paper designs a vehicle theftagainst system the based on GSM munication platform and GPS satallite positioning by integrating a lower hardware scheme circumstance, to bine positioning with against theft function of vehicle, to enhance the development efficiency, also is advantageous for software and the hardware later period maintence and the revision.Integrating the traditional vehicle alarm technology and GSM/GPS technology and according to the designing principles of embedded system, the system builds up a mutual platform among the vehicle monitor and control protocol based on GSM short message. Vehicle owners and the monitor center can monitor the state of the vehicle and send controlling instructions by means of SMS, so as to realize alldirectional vehicle alarm and monitor.Key words: Vehicle Alarm System；Embedded System； Communication Protocol； Remote Monitor目錄引言 ............................................................................................................................................................11. 選題的背景 ..........................................................................................................................................2 課題研究的內容和意義 ................................................................................................................2 研究的主要內容 ...................................................................................................................2 課題研究的意義 ...................................................................................................................2 課題研究背景 ................................................................................................................................22. 系統(tǒng)的硬件設計 ..................................................................................................................................4 系統(tǒng)的原理圖 ................................................................................................................................4 GSM 模塊 .......................................................................................................................................4 系統(tǒng)的通信平臺 .................................................................................................................4 GSM 網絡的簡介 ..................................................................................................................5 GSM 的基本特點 ..................................................................................................................5 GSM 的系統(tǒng)功能 ..................................................................................................................5 GSM 模塊 TC35 簡介 ............................................................................................................5 TC35 模塊的初始化 ..............................................................................................................6 MSP430 單片機簡介 .....................................................................................................................7 MSP430 系列單片機的特點 ................................................................................................7 MSP430F149 單片機簡介 ....................................................................................................8 單片機處理電路 .................................................................................................................9 系統(tǒng)的定位技術 ............................................................................................................................9 定位技術的選擇 .................................................................................................................9 GPS 定位系統(tǒng)介紹 ..............................................................................................................9 GPS 定位基本原理 ............................................................................................................10 GPS 功能電路 ....................................................................................................................11 防盜系統(tǒng)的設計 ..........................................................................................................................11 防盜系統(tǒng)的總體設計 .....................................................................................................12 防盜系統(tǒng)的功能設計 .......................................................................................................13 系統(tǒng)電源 ......................................................................................................................................13 汽車供電控制部分 ......................................................................................................................143. 系統(tǒng)的軟件設計 ................................................................................................................................16 系統(tǒng)程序模塊 ..............................................................................................................................16 主控模塊 .............................................................................................................................16 主要子程序模塊的設計 .....................................................................................................16 防盜系統(tǒng)的工作過程 ..................................................................................................................174．結束語 .....
