基于ZigBee的车载交通灯监视系统设计

Design of Vehicle-mounted Traffic Light Monitoring System Based on ZigBee

为解决驾驶员在城市道路十字路口遭遇前方大车遮挡、恶劣天气及眩光时,出现交通灯"盲视"现象而引发交通事故的问题,利用ZigBee灵活的组网功能,在城市道路的十字路口安装交通灯监视系统的主控端,在各个车辆上安装车载终端,形成基于ZigBee的车载交通灯监视系统。系统主控端承担网络管理和交通灯信息发送任务,车载终端负责交通灯信息数据接收、交通灯信息LCD显示和交通灯相位切换前语音提示驾驶员的任务,两者通过ZigBee进行无线通信,圆满地解决了驾驶员的"盲视"问题,极大地提升了十字路口的安全通行率。

In order to solve the problem of traffic accidents caused by traffic lights"blind"when drivers encounter the block,bad weather and glare in front of them at urban road intersections,ZigBee’s flexible networking function is used to install the main control end of traffic light monitoring system at urban road intersections,and vehicle terminals are installed on each vehicle to form ZigBee Based vehicle-mounted traffic lights monitoring system.The main control terminal of the system is responsible for the task of network management and traffic light information sending,and the vehicle terminal is responsible for the task of traffic light information data receiving,traffic light information LCD display and voice prompt to the driver before the traffic light phase switching.The two wireless communication through ZigBee successfully solves the problem of"blind vision"of the driver and greatly improves the safe traffic rate of the intersection.
