基于3S的IVLNS技术研究实验平台

智能交通系统是21世纪城市交通的发展方向，智能车辆定位导航系统(IVLNS)是其核心，因此开发IVLNS技术研究的实验平台，具有十分重要的意义。阐述了自行研制的基于3S(GPS，GIS和GPRS)的IVLNS的组成，对各组成部分的功能及其实现进行了详细说明，对该系统的车载软件及相关技术进行了介绍，并给出了实验平台的初步实验结果。实验结果表明：该实验平台能够对车辆导航与定位，并为智能交通关键技术的进一步研究提供了基础。

Experimental Platform for Researching IVLNS Based on 3S

In the 21st century,Intelligent Transportation System(ITS)has become the inevitable trend of city traffics,of which Intelligent Vehicle Location and Navigation System(IVLNS)is the central part,so it is important to develop an experimental platform for IVLNS.An architecture of IVLNS based on 3S(GPS,GIS and GPRS)was proposed,the function and realization of every part of the system was described,the software controlling the vehicle unit and the relative technology was introduced,and the primary result of the experiment on the experimental platform was presented.The experimental result indicates the experimental platform can locate and navigate for vehicles,and it also provided the basis for further research on the core technology of ITS.
