摘要
针对传统的交通灯采用定时原理变换信号灯,不能很好的解决交通拥堵问题,设计了基于ZigBee的智能交通信号灯系统,可根据车流量将路口内、路口间信号灯实时自主调节。分析讨论了ZigBee无线传感控制网络的组建、传感器的选型以及系统软件的设计。采用综合性能最优的ZigBee通信技术,完成对协调器及终端节点的程序设计,制定了数据通信协议。软件部分采用IAR集成开发环境设计客户端程序。结果表明通过ZigBee网络的建立和数据的传输可根据实时车流量对交通信号灯进行合理动态配时。
For the traditional traffic light with timing principle can＇t solving traffic jam problem,intelligent transportation traffic lights was designed based on ZigBee,which may automatically regulate traffic lights in crossing and among crossings according to traffic flow.It was analyzed and discussed to build ZigBee wireless sensing control network,select sensor type and design system software.The optimum ZigBee communication technology is used to complete the programming for coordinator and terminal node,to make data communication agreements.The software uses integrated development environment designs client program.The result shows that on the basis of building ZigBee network and transporting data,it is possible to control traffic lights reasonably by traffic flow on real time.
