摘要:针对当前车辆速度监测方法存在的问题,本文提出了一种基于 RFID 的智能交通速度
监控系统的设计方案,并完成系统部分软硬件的设计。该方案是以非接触双向通信的 RFID
技术作为理论基础,设计了工作频率在 915MHZ 的射频识别智能交通速度监控系统。在读写
器硬件设计中,选用了超低功耗控制器 MSP430 作为主控芯片,软件部分采用了 C 语言进行
编程。实际应用表明,该系统可有效地在高速公路全路段实现速度监控,保障了人们出行安
全。

Abstract: For the problem of the current vehicles speed montior , a design of intelligent traffic
speed monitoring system based on RFID was proposed pleted the part of the system's
hardware and software program is based on non-contact and both-munication
RFID technology as a theoretical basis,designed smart traffic speed monitoring system that work
at a frequency of 915MHZ frequence hardware part of the reader with
ultra-low-power controller,MSP430 is the master chip,and the software part with the C language
experiment and application show that the system can effectively realize speed
monitoring in the highway and provid people travel security.
