【摘要】 随着信息技术的发展，汽车防盗技术已经从最初的机械式汽车防盗系统发展到最新的基于GSM／GPS的网络式汽车防盗系统；而在国内，由于价格上和技术上的原因，普通的电子式汽车防盗器还是占据主流地位。针对市场上流行的普通汽车防盗器产品大多数都存在着防盗功能单一、可靠性低、缺乏跟踪监控功能等缺陷，此外，大部分网络防盗系统都是通过将高主频嵌入式CPU与嵌入式WinCE或Linux操作系统相结合而构建的，而本文则是利用较低的硬件配置环境设计了一种基于GSM通讯平台和GPS卫星定位的汽车防盗系统，实现汽车导航与防盗功能的结合，提高了开发效率，也便于软件和硬件后期的维护与修改。该系统集成传统的防盗技术和GSM／GPS技术，通过嵌入式系统设计原理，利用基于GSM短消息的无线通信协议，构建了一个在车主、监控中心和汽车之间通信的交互平台，车主和监控中心可利用短消息对汽车状态进行监控并可以发送控制指令，从而实现了全方位的汽车防盗监控系统。本文论述了汽车防盗系统所涉及基本原理，包括系统数据信息处理中用的GSM短信息协议、PDU格式、AT指令和国际航海电子协会标准导航NEMA0183协议。同时，也详细介绍了系统的硬件构成，包括系统电源电路、微控制器MSP430F149、GSM无线模块TC35、GPS接收模块以及外围的检测控制电路。在软件设计上采用模块化方法，即将整个系统软件分为几大模块：系统模块、防盗器接口模块、GSM处理模块和GPS处理模块等，供主控模块调用；利用VC++6.0设计上位机监控软件，完成对GSM模块相关指令的测试和短消息的收发功能。本系统相对于市面上的其它网络式汽车防盗系统的不同之处在于，可以将部分已经安装在车主汽车上的普通电子式防盗器改装成网络式汽车防盗系统，从而大大降低用户的费用投入，提升了产品的性价比。更多还原

【Abstract】 With the economic development, the vehicle theft-against technology has upgraded from the original mechanical mode to the latest GSM/GPS-based network mode after several generations. But in China, considering the price and technology, the common electronic vehicle alarm equipments are still the dominant ones.In view of the deficiencies of most common vehicle alarm equipments prevalent in the market, such as single alarm ability, low security and lack of tracking and monitoring ability, Moreover, most of the network theft-against systems are made by integrating a high main frequency embedded CPU and an embedded WinCE or Linux operating system, but this paper designs a vehicle theft-against system based on GSM communication platform and GPS satellite positioning by integrating a lower hardware scheme circumstance, to combine positioning with against theft function of vehicle, to enhance the development efficiency, also is advantageous for software and the hardware later period maintenance 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 owner, the monitor center and the vehicle by using 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 all-directional vehicle alarm and monitor.This article elaborates basic principle of vehicle localization and the theft-against system, including protocol of SMS(GSM07.05), the PDU format, AT Instruction and the protocol of navigation(NEMA-0183)used in the system. Simultaneously, the construct of hardware is introduced in detail,including power circuit of system,Microcontroller MSP430F149,wireless GSM telecommunication module TC35,GPS module and outer control circuit. Uses the modular method in the software design, soon the overall system software divides into several big modules: System module, security interface module, GSM processing module and GPS processing module and so on, for master control module transfer; Using the VC6.0 designs in the position machine monitoring software, completes to the GSM module correlation instruction test and the SMS receiving and sending function.Different from other network vehicle alarm systems in the market, the system can refit some common vehicle alarm equipments, which have been already fixed on the vehicles, into network vehicle theft-against systems. Consequently, the expense of the user can be greatly reduced and the performance-price ratio of the product increased.更多还原
