车辆监控系统中车载GPS GSM双定位终端的设计

随着我国交通运输业的发展,车辆的跟踪监控在物流等行业显得越来越重要。车辆监控系统中,车载定位终端多采用GPS技术进行定位,而GPS定位虽然定位精度高但存在盲点较多的缺陷。而基于GSM网络的位置服务恰恰能弥补GPS定位盲点较多的缺点,从而可以有效地克服GPS定位盲点多的缺点,故该定位终端集成了GPS和GSM网络两种定位方法的优点。实验结果表明,该定位终端可达到准确、实时、全天候、无盲点定位,大大提高了定位性能。

Design of Dual Vehicle Mobile Positioning System Based on GPS and GSM Tracking Terminal

The vehicle tracking is more and more important in the business of conveying goods following the development of the traffic.GPS always be used in vehicle tracking terminal in the mobile positioning system.GPS tracking terminal is exactitude but also has some limitation such as blind spot.This treatise discusses the method of equalize for the common vehicle mobile positioning system by using GSM tracking terminal which accordingly effectual the problem of blind spot.This vehicle mobile positioning in possession of two strongpoint GPS and GSM.It is clear to the result of experimentation that the vehicle mobile positioning system is exact real time all-weather and no blind spot,so the orientation of capability is much more enhanced than before.
