车辆监控系统中车载GPS定位终端的设计

随着中国交通运输业的发展,车辆跟踪监控系统在物流等行业的作用越来越重要。基于全球定位系统（GPS）的车辆监控系统将发挥越来越重要的作用,车载定位终端多利用GPS技术进行定位,但GPS定位也存在盲点多的缺陷,而基于GSM网络的恰好能弥补GPS定位盲点多的的缺点,从而提高了定位的精度。介绍了监控系统的组成和工作原理,该系统能提供车辆的定位、跟踪、监控、防盗报警等功能。

Design on GPS Terminal Vehicle Monitoring System

With the development of communications and transportations,the vehicle tracking and monitoring has become more and more important in logistic service,and the vehicle monitoring system based on GPS plays an even more important role.The vehicle Location terminal mostly use GPS technology in positioning,and however,there also exist defects of multiple blind spots in GPS postioning,while the GSM pstitioning could be able to remedy its defects of multiple blind spots,thus raising the accuracy of positioning.This paper describes the composition and working principle of the monitor system.This system could provide various functions,including vehicle location,tracking,monitoring,and guard-against-theft alarm.
