基于GPS/GPRS的车载监控终端的设计与实现

The design and implementation of vehicle carried terminal based on GPS/GPRS

现代智能交通系统对车辆精确监控与调度的需求日益迫切。本文介绍了一种以uClinux、PHILIPSLPC2210微处理器为软硬件平台,利用WAVECOMQ2406B、HOLUXGM82为功能模块的车载监控系统,该系统主要应用在集群车辆监控调度系统中,利用GPRS网络可将车辆的实时方位上传至监控中心,并依据监控中心的指令执行信息采样速率控制等各项操作。重点阐述了系统的硬件平台搭建和系统任务的划分;介绍了串口驱动的移植。实际运行结果表明,系统达到设计要求,实现了控制中心实时监控车辆行驶状态,加强了对车辆的管理。

With the development of the modern intelligent transportation system, the accurate vehicle monitoring and scheduling system is greatly needed nowadays. This article introduced a new design of vehicle carried terminal based on the GPRS/GPS. The system, which is making use the uClinux. PHILIPS LPC2210 Microprocessor as platform of software and hardware and WAVECOM Q2406B, HOLUX GM82 as function modules, will be used in the Integrated vehicle monitoring and dispatching center. It can upload the direction to the center time to time and also can execute some operations such as control the information sampling rate according to the instruction from the monitoring and dispatching center. The emphasis of the paper is on the process of establishing the hardware platform, the division of the tasks and also the transplantation of the serial driver. The better test results showed that the system had met the design requirements already. It can achieve real-time vehicle monitoring and strengthen the management of the vehicles effectively.
