| 摘 要： | 文章根据自主设计的一种高速公路汽车防碰撞预警系统，车载装置检测车辆运行状况，判断车辆运行是否异常或有故障，自动或手动发送信息预警，高速公路路边装置接收车载装置的信息，根据信息类型向该车辆行驶方向后面的路边装置发送信息，后面的路边装置将车辆前方的交通异常状况发送给车载装置。文章中构建Zigbee无线网络，设计无线通信协议，规范了车载装置与路边装置，路边装置相互之间，车载装置与入口测试启动装置，出口关闭装置，通信频率设置的通信协议，给出了程序流程图，经过测试满足高速公路汽车防碰撞预警系统的应用要求。

| Abstract: | Presented a highway motor vehicle collision warning systems, autonomous speed highway-vehicle devices on vehicles, and to determine whether the vehicle speed set security value below the highway automatically, you can manually send message warning, freeway on-ramp test starter on highway vehicle performance testing device, start the highway-vehicle device, set up safe speed limit, Highway closed highways closed device-vehicle device features Highway direction of travel frequency settings, device settings Highway truck-mounted communications device in the highway direction frequencies, expressway monitoring and communication device real-time monitoring of vehicle travel, and while the vehicles are in normal form, anti-collision warning output; The highway vehicle collision warning systems can be monitored in real time and receive the abnormal traffic safety warnings ahead, sent the safe speed limit values due to weather and road conditions change, improves the safety of highway traffic. |
