基于ZigBee的无线交通同步控制系统的设计与实现

Design and Realization of Wireless Synchronized Traffic Control System Based on ZigBee Technology

通过研究ZigBee协议和无线传感器网络同步控制算法,提出了基于ZigBee技术的交通控制系统方案,设计了基于ATmega128L单片机、CC2420射频收发器等芯片的硬件节点,实现了无线交通系统通过对路面交通信息的采集,传输到交通指挥中心,再通过关卡节点发送数据包来对交通信号灯进行无线控制。研究及实验结果表明该设计在实际生活中具有很好的实用价值。

The ZigBee agreement and the Wireless Sensor Network synchronization control algorithm were studied.A Traffic Control System based on ZigBee technology is proposed.The hardware node was designed based on ATmega128L microcontroller,CC2420 RF transceiver and other chips.A wireless traffic system was improved to collect the information of the vehicle,and transfer data to traffic control center.The traffic control center sent data packets through the sink node to the wireless traffic lights.Testing results demonstrate that the system design has a good practical value.
