【摘要】 车载移动终端是车辆定位监控系统的重要组成部分，也是目前我国交通运输管理领域需求迫切、极具市场潜力和经济效益的应用项目之一。本文根据车辆监控系统的原理和车载终端的主要功能，提出一种基于ARM和μC／OS-Ⅱ的车载GPS／GPRS移动终端的设计方案。该方案采用嵌入式系统设计思想，以S3C44B0X处理器为硬件平台，扩展了GPS定位信息接收模块、GPRS通信模块以及其他外设，完成硬件电路设计。移植了实时多任务嵌入式操作系统μC／OS-Ⅱ、图形界面系统μC／GUI和FAT16文件系统，研究分析了μC／OS-Ⅱ多任务调度和μC／GUI在系统中的应用，完成了NMEA0183协议解析、GPRS数据传输等用户应用程序的开发，通过软硬件联合调试，下载目标程序到硬件平台，验证了程序的正确性。实现了车辆定位、报警、监控、通信、数据传输等功能。本系统是集嵌入式系统技术、GPS卫星定位技术、GPRS通信技术为一体的综合系统，提高了系统的实时性、可扩展性，降低数据传输费用，可以提高车辆运输的效率与安全，是解决城市交通问题的有效途径。可以应用于公安、物流、银行、智能交通等集团用户，具有广泛的市场前景。更多还原

【Abstract】 With the development of city and the manifold of vehicles, the security and management of vehicles have become a serious question of society. The market of vehicle position monitor system is very large. Vehicle mobile terminal is a key part of vehicle position monitor system. It is an integrated system based on ARM, GPS and GPRS. This system may dramatically improve the efficiency and security of vehicles, and enhance the capability of traffic.Firstly, an introduction on the significance, development, related technology and application fields of vehicle mobile terminal was introduced in this thesis. Then the principle of vehicle monitor system and the main function of the terminal were described. The design of hardware and software were presented. The application ofμC/OS-Ⅱin the system was demonstrated in the following parts. Finally, the debugging process of the hardware and software were described.In order to improve capability of real time data transmission and reduce cost of the system, the ARM embedded hardware platform, GPRS network as well as real time operating systemμC/OS-Ⅱwere introduced in this thesis. So data transmission becomes much easier and cheaper than it is done by SMS, and the function of system is easily expanded. Vehicle mobile terminal will be applied widely in the fields of police, logistics and bank, and have a promising market in the future.更多还原
