摘要随着电子技术和计算机技术的蓬勃发展，无线定位追踪技术在现代社会中发挥 着重要的作用，近几年无线定位追踪系统取得了令人引人注目的进展，如农业车辆 导航系统、车载导航系统、惯性导航系统（INS）等。另外，无线定位技术的快捷 可靠激活了城市交通、医疗卫生等领域的发展潜力。因此，对无线定位技术的研究 具有重要的理论意义和应用价值。83797

针对目前市场上无线定位设备产品的定位和通信方式过于单一的问题，本课题 设计了一个混合网络无线定位追踪系统，系统以 GSM 网络为主要通信方式，GPRS 网络为辅助通信方式，通过 GSM/GPRS 网络完成定位数据的通信，这样用户既可以 通过手机查询定位追踪信号源的具体经纬度等信息，也可以通过 PC 软件实时监控 定位追踪信号源的地理位置，在不同情境下两种定位方式各有优势。

本文设计的系统采用 GPS 定位技术，使得定位具有全天候、全球性特征，且适 用于多种恶劣环境下的定位工作。将 GSM 和 GPRS 网络的结合实现数据的两种传 输方式使远程监控更具多样性。设计的系统还具有体积小、高续航、易携带等优势。

Abstract With the rapid development of electronic technology and computer technology,wireless location technology plays an important role in modern society。Wireless location technology has undergone impressive advances in recent years,such as agricultural vehicle guidance system,vehicle navigation system,inertial Navigations Systems (INS)。Moreover,The high speed and reliability of wireless location technology has potential for the development of urban transportation, medical care and other fields。Therefore,the research of wirelesslocationtechnologyhas important theoretical significance and application value。

Aiming at the way of positioning and communication of wireless positioning equipment products in the market is too single,The project designs an hybrid network wireless location tracking system which uses GSM network as it’s main communication method and GPRS network communication as a secondary way,completes the positioning data communication via the GSM/GPRS network。In this way,users can monitor the specific latitude and longitude of the location tracking signal sourcethrough mobile phone, can also through the PC software to monitor the location of the location tracking signal source in real-time,In different situations, two kinds of positioning methods have their own advantages。

In this paper, the design of the system using GPS positioning technology,makes the positioning of the all-weather, global features,and applicable to a variety of harsh environment of the positioning work。The combination of GSM and GPRS network can complete the two transmission ways of data,and it can make remote monitoring more persity。The design of the system also has a small size, high battery life , easy to carry, and other advantages。

Keywords:Hybrid network；wireless location；GPS；GSM/GPRS
