基于GPS/DR与GIS集成的城市车辆实时监控系统的设计与工程应用

City Vehicle Navigation Real Time Control System Design Based on Integration of GPS/DR and GIS and Its Application

结合香港某种车辆调派系统和南京市某银行运钞车实时监控系统的工程应用,给出基于GPS/DR/GIS集成车辆导航系统的设计与组成,以及系统各个模块之间的相互关系;研究并提出适合车辆导航数字地图的数据组织,大地坐标系与WGS84坐标系、WGS84坐标系与独立坐标系间的相互转换关系;详细介绍本系统在不同工程应用中各自实现的功能。本系统在香港实地跑车实验中,在无GPS信号的情况下,运用DR/MM定位模块连续定位15min后,测得其定位精度小于5m。

The paper introduces the application of the vehicles assign system in Hongkong and the real time control system for bank paper money transport in Nanjing and explicates the Vehicle Navigation System design that is based on GPS/DR/GIS,made up of modules and connection among modules,with digital map data structure for vehicle navigation,and conversion between earth coordinate and WGS84 coordinateThe system position precision is less than 5 meter under the condition that dead?reckon and map?matching are used to position vehicle continually 15 minutes without GPS signal
