基于GPS手机出警导航系统的数据库研究

A Database Approach to GPS Phone of Navigation System

随着科技的发展,作为终端设备的GPS智能手机越来越多地应用于诸如公安、物流、测绘、车队管理等行业.定位精度高,使用方便稳定等优点,使得GPS智能手机成为这些行业进行信息化改造时的首选.GPS手机出警导航系统基于Windows Mobile操作系统,采用了全球卫星定位技术,监控中心通过解读GPS信息定位出巡逻警员当前和出警目标点位置,巡逻警员使用解码函数来解析监控中心发送的出警短信内容,通过GPS手机导航及特设时时通讯和高精度放大/缩小地图功能到达出警目标点.

With the development of technology, the GPS mobile phone,as a terminal equipment,has been more and more applied to public security ,logistics, mapping, vehicle management and other industries. Its high positioning accuracy, convenience and stability make it first choice in the information transformation. Based on Windows Mobile operating system, GPS navigation system uses global satellite positioning technology;the monitoring center,through the interpretation of GPS information,can determine the now position and target position of patrol officers. Patrol officers use the decode function to resolve the warning content of the message that the control center sends out;through the GPS mobile phone navigation and ad hoe mobile communications and high-precision constant zoom in/out the map function, they can reach the police target.
