基于GPS/GPRS的车辆监控系统中车载台的设计

Design of vehicular-locating terminal device in the vehicle monitoring system besed on GPS/GPRS

在以MSP430F449芯片为核心的基础上,通过对GPS接收机(M12)、GPRS通讯模块(MC35)以及液晶显示屏(LCD)等外围模块的控制,设计了车辆定位监控系统中车载信息终端设备——车载台。该设备可为监控中心提供完整全面的车辆运行和定位信息,方便对车辆的监控、调度、即时定位,可以实现车辆实时动态信息的全程管理。最后,提出了日后完善该设备功能的几点想法。

In this paper, on the base of the MSP430F449 chip, a vehicuhr-locating set, a kind of vehicle information terminal device, is designed through the control of GPS receiver （M12）, GPRS commtmication module （MC35） and a series of periphery modules including the liquid crystal disphy monitor （LCD） and so on. The set can provide a comprehensive information of vehicles＇ movement and localization for the monitoring center. It can facilitate the monitoring, the dispatch and the immediate localization and realize the entire journey management of the vehicles＇ real-time dynamic information. At last, some ideas ofperfecting the device＇s function future are put forward.
