基于DAB技术的智能交通车载终端

An Intelligent Vehicle Terminal Based on Digital Audio Broadcasting

基于数字音频广播(DAB)技术,文章提出了一种交通诱导信息广播系统和一种车载智能终端。交通诱导信息广播系统将高速发展的广播数字化技术与城市交通智能管理相结合,是集信息采编、信息发布、信息移动接收、交通实时导航、娱乐于一体的信息处理平台;车载智能终端基于DAB技术,是用于对车辆现代化管理的设备。交通诱导信息广播系统依托移动网络可以从服务车辆上获得全球定位系统(GPS)定位信息,从而监控和跟踪车辆;车载智能终端可以接收DAB信道的实时广播、动态路况、车辆的导航路径等信息。

In this paper, we propose a traffic and travel information （TTI） system and intelligent vehicular terminal. The TTI system combines digital audio broadcasting （DAB） and intelligent urban traffic management. It is a platform for receiving and disseminating information from mobile sources, and provides real-time navigation, tracking, and entertainment. The intelligent vehicular terminal is designed for modern vehicle management and is based on DAB. The TTI broadcasting system obtains location information from the mobile network in order to track vehicles, and a vehicle ＇ s intelligent terminal receives broadcasting, road information, and navigation in real-time from the DAB channel.
