基于GPRS的实时路况车载导航终端研究与实现
Study and Implementation of Real-Time Traffic Information Navigation Terminal Based on GPRS
摘要
Abstract
In order to balance the road usage and reduce the traffic jam, a new real-time traffic information navigation terminal is designed based, on the research of GPS and GPRS and is used to receive the real-time traffic information of city. The terminal is designed using the embedded system technology and is made up of SIM100 module, GR-87 module and S3C2410A CPU. GPRS is used as the technology of communication and the server of information center is allocated a stable public network IP. The map data is stored in TAB format and is coded according to TTI(traffic and traveler information) message. At last, the map is showed in ARM-Linux OS using MiniGUI library and the real time traffic information is marked on it. The result shows that automobile is positioned correctly and map is shown fluently.关键词
