摘　　要：为了实现对汽车速度的实时分布式监测,利用无线射频识别(RFID)多读写器组网技术,设计了汽车速度分布式监测系统。将安装在道路沿线的读写器组成网络,通过无线速度传感标签采集汽车速度及身份资料,将相关信息发送给分布点所在的读写器。当汽车速度超过限速要求时,系统以语音方式提醒驾驶人员,联成网络的读写器将相关信息传送给控制中心,可实现数据的存储和实时显示。实验表明,该系统能准确采集汽车速度等信息并实时传输和处理,实现了对汽车行驶速度实时分布式监测,可有效避免汽车超速行驶导致交通事故频发的问题。To realize real-time and distributed monitoring the actual speed for vehicles,the speed monitoring system was designed for vehicle based on RFID readers network.The readers installed along the roadside are connected with network,the actual speed of vehicle is acquired by a speed sensor–tag,and identity information of the vehicle and its actual speed are sent to readers through RFID tag.When the vehicle drives over the limited speed,the system can voice alarm to the driver in speech sounds,the vehicle identity and its actual speed are transmitted to the control center by the readers which connectd with network,where these information are stored and shown real-time.Experimental results show that this system can acquire vehicle speed accurately and process and transmit it real-time,achieve the function of vehicle speed monitoring and its intelligent early warning,and the accidents caused by vehicle speeding can been avoid effectively.
