【摘要】 进入20世纪90年代,嵌入式技术已成为通信和消费电子类产品的共同发展方向。伴随着嵌入式技术的发展和提高,很多其它高技术应用于嵌入式系统中,全球卫星定位系统(GPS)就是之一。GPS可以满足很多社会需求,重要车辆的定位追踪就是它的一个重要应用。我国车载追踪系统的研究虽然起步较晚,技术基础比较薄弱,但是随着我国汽车工业的发展,车载追踪系统市场需求巨大,前景广阔,因此课题具有良好的社会意义和广阔的市场前景。本文对于课题的目的和意义进行了综述,并在原理上详细的阐述了课题中几个核心的技术与应用,包括GPS定位系统,GPRS通用分组无线业务,Windows CE嵌入式操作系统。追踪系统的基础是硬件电路设计。系统在硬件上分为监控终端和追踪处理终端两部分。结合系统的实际要求,分别选取ATmega162单片机和TFT_LCD一体化电脑作为硬件电路核心处理器。硬件电路的设计主要分五大部分来实现:监控终端;追踪处理终端;GPS模块;GPRS模块;电源模块。文中主要介绍了各部份的功能以及设计要求。追踪系统的核心是软件设计。其最终目的是完成最终实现定位追逐,信息查询等功能。软件系统基于Windows CE内核,主要内容包括:监控终端和追踪处理终端对于GPS模块中定位信息的提取与处理;实现GPRS模块与GPRS模块间的数据传输;在触摸屏上完成显示界面的设计与实现等,同时,电子地图的显示和功能的开发也是软件设计的重要组成部分。更多还原

【Abstract】 After 1990s, embedded technology has become the direction of common development between the communications and consumer electronic products.As the development and improvement of the technology, many other high-technologies are applied to the embedded systems, for example, global positioning system (GPS). GPS could meet many needs of the community, and the vehicles’tracking is one of its important applications. In our country, we start to research on car tracking system later than others, and related technology is limited. With the development of car industry, the market of car tracking system will become more and more huge.So the subject has a great social meaning and wide market prospect.The purpose and significance of subject are reviewed in the paper, and several principle of core technologies and the application have been carried on in detail, including GPS global positioning system, GPRS general packet radio service and Windows CE embedded operating system.Tracking system’s hardware design is the foundation.This system divides into the monitoring terminal and tracking process terminal on the hardware. With the actual situation of system, the paper separately selects ATmega 162 microcontroller and TFT_LCD integrated computer as the core microprocessor of hardware circuit. There are five major parts to achieve in hardware circuit design: the monitoring terminal; tracking process terminal; GPS module; GPRS module; power module. The paper mainly describes the functions and desig requirements of all the parts.The software design of the system is the core. The ultimate goal is that completing the functions of the localization tracking, information inquiry and so on. The software system is based on the Windows CE kernel, the primary coverage includes: Extracting and processing the information of location from GPS module by the monitoring part and tracking process part; Realizeing the data transmission between the GPRS modules; Completeing the design of the demonstration interface on the touchscreen. At the same time, the electronic map’s demonstration and the function’s development are also the important component of the software design.更多还原
