摘要
针对目前城市交通道路拥堵问题,设计了一种具有车流量检测功能的智能交通灯控制系统,采用环境监测采集单元实时采集环境数据,并提供给译码器使控制器做出相应的响应;利用每个信号组的队列长度从而改进队列测量的三种算法,同时将各个监测器传来的数据进行准确的分析,判断路况,实时调整绿灯时间保障通行畅通;利用GPRS通信系统保障通信质量,各个路灯之间采用ZigBee无线Mash自组网以达到故障检测功能。实现了路灯自控,路灯环境参数检测响应,实时车流量检测估算,故障报修,网络自愈等功能。
In view of the present urban traffic congestion problem,a flow detection function of intelligent traffic light control system is designed,the environmental monitoring data acquisition unit is used for real-time acquisition environment,and decoder controller is provided to make the corresponding response.The queue length of each group of signals is used to improve the three algorithms of the queue measurement,as well as to each monitor,accurate analysis of data,judgment road,real-time adjustment of green time guarantee to traffic flow.The GPRS communication system is used to guarantee the communication quality,ZigBee wireless Mash is used in each street lamp to achieve the fault detection function.It has realized the function of street lamp control,street lamp environment parameter detection response,real-time traffic flow detection estimation,fault repair,network self-healing,etc.
