一种基于ZigBee的防追尾预警系统

The Early Warning System of Anti-collision Based on ZigBee

基于ZigBee的防追尾预警系统通过等间隔置于道路上的协调器和车载终端实现车联网,完成车车互联、信息共享。利用道路节点对道路进行分段管理,利用车载终端的GPS和RFID读取器实现车辆的位置、速度与行车道的信息获取,最后利用最小安全距离模型实现车辆防追尾的预警,并在实物测试中得到了验证,证明了系统的可行性。

Based on ZigBee,the early warning system of anti-collision realizes the Internet of vehicles through the coordinator and on-board terminal placed on the road at equal intervals,so as to complete the vehicle interconnection and information sharing.The road node is used to manage the road in stages,and the GPS and RFID reader of vehicle terminal are used to obtain the information use road nodes to manage road segments,and use GPS and RFID readers of on-board terminals to obtain information about the location,speed,and lane of the vehicle.At last,the minimum safe distance model is used to realize the early warning system of anti-collision,and it is verified in the physical test,which proves the feasibility of the system.
