摘要
提出一种城市车辆间通信系统。系统由PowerPC硬件平台与嵌入式Linux软件平台构成,采用全球定位系统技术实时获取车辆定位信息,通过专用短距离通信技术使车辆间形成高速双向交互式通信,利用ARM9搭载Linux系统实现触屏显示。测试结果表明,该系统能实现车辆间高速、可靠、低延时的通信。
This paper presents a design strategy for system among city vehicles in communication.The system is composed of PowerPC hardware platform and software platform based on embedded Linux operating system.Real-time vehicle location information is obtained by Global Positioning System（GPS） technology.Dedicated Short Range Communication（DSRC） technology is employed to achieve high-speed and two-way interactive communication between city vehicles.ARM9 loaded with embedded Linux operating system plays a role of touch screen display.Test result shows that the system can achieve high-speed,reliable,low-latency communication between vehicles.
