摘要
介绍了基于TI公司的MSP430F149单片机的车辆监控终端的设计与实现。系统结合GPS车台,对多任务进行实时处理,实现通讯、定位、报警以及监控中心无线遥控等功能。监控中心从终端发送的信息中解析出数据与GIS进行地图匹配,实现对移动终端的定位,同时根据报警信息查询数据,显示该终端用户的资料及报警类型。移动终端显示屏实时显示该车辆运行的基本状态,也可接收来自中心和用户手机的控制命令,并根据命令执行相应的动作,实现系统数据双向传递。终端提高了汽车运营公司的管理能力,且功耗低、体积小、操作简单,便于系统管理维护。
The design and implementation of the vehicle monitoring system based on TI MSP430149 is described. The system provide multi-task real processing, implement the communication, position, warning and wireless remote control function. The monitoring center distill the efficacious information, and the mobile terminal is located by map matching with position information and electronics map which is built by GIS system. At the same time, the mobile terminal user data and the warning reason are displayed by searching database. The mobile terminal LCD display the vehicle state rapidly. It can also receive the central and user phone dictate. So, the terminal and server can communicate with each other and improve the level oft car＇ s management ability. The terminal has the advantages of low power consumption, small size, easy using and it is convenient to update, improving the level oft car＇ s management ability.
