基于无线网络的智能交通监控系统研究

Research on Intelligent Traffic Monitoring System Based on Wireless Network

本系统基于无线传感网络对智能交通监控系统进行开发研究,用以解决目前城市道路交通拥堵、道路利用率低下等问题。基于无线传感网络的智能交通监控系统利用ZigBee网络进行网络架构,由终端节点、监测站协调器和监控中心三部分组成。终端节点为具有无线收发模块的CC2530和磁阻传感器组成,用以完成车辆流信息的采集;监测站协调器由具有无线收发模块的CC2530和TMS320F28335组成,用以完成对各路口车辆流信息的接收,并将采集到的信息通过Internet网络传输给监控中心;监控中心通过计算、分析,得出各路口拥堵情况,并将拥堵情况通过车联网技术发送给监控中心车辆电子信息卡数据库里的车主,提醒车主根据实时路况,提前更改路线,避开道路拥堵。这里通过车牌号与车辆的其它信息进行唯一对应,建立车辆电子信息卡数据库。

This system is based on wireless sensor network for intelligent traffic monitoring system development research,to solve the current urban road traffic congestion,low road utilization and other problems.The intelligent traffic monitoring system based on wireless sensor network uses ZigBee network for network architecture,which consists of three parts:terminal node,monitoring station coordinator and monitoring center.The terminal node is composed of CC2530 with wireless transceiver module and reluctance sensor to complete the collection of vehicle flow information.The monitoring station coordinator is composed of CC2530 and TMS320F28335 with wireless transceiver module,which is used to receive the vehicle flow information at each intersection and transmit the collected information to the monitoring center through the Internet network.Through calculation and analysis,the monitoring center obtains the congestion situation at each intersection,and sends the congestion situation to the car owners in the vehicle electronic information card database of the monitoring center through the Internet of vehicles technology to remind the car owners to change the route in advance according to the real-time road conditions to avoid road congestion.Here,through the unique correspondence between the license plate number and other information of the vehicle,the vehicle electronic information card database is established.
