摘要
介绍了一种无线交通信号控制系统,该系统是先进的短程无线通信(Zigbee)技术和光耦-固态开关控制技术的有机结合,其性价比高,特别适合应用于没有通信网络的路口、道路和桥梁的交通信号控制。该系统所采用的无线控制技术还可应用于其它方面,如车辆违章图像信息的抓拍和传输。
A traffic signal wireless control system is introduced which is the organic combination between advanced short - range wireless communication （Zigbee） technology and control technology of photocoupler - solid state switch. Its ratio of performace to price is high, and is especially suitable for the traffic signal control at intersections,on roads and bridges without communications network. The wireless control technology of this system can also be applied in other aspects,such as grasp and transmission of pictures of the vehicles driving against traffic rules.
