一种基于RFID的汽车速度检测及预警管理系统，该系统通过自行开发的汽车数字化速度仪采集汽车实际行驶车速信息，当汽车实际行驶的速度超过限速要求时，系统不仅能够以语音方式提醒驾驶人员，同时还将汽车身份资料及实时行驶的速度等信息通过RFID电子标签发射给路边安装的读写器，最后通过网络将相关信息传送给控制中心，并进行数据存储和实时显示，从而实现了对汽车实际行驶速度监测及预警功能。-An RFID-based car speed detection and early warning system, the system through a self-developed car digital speed instrument collected the car the actual driving speed information when the car actually traveling faster than the speed limit requirements, the system can not only remind drivers by voice staff will also be the vehicle identification information and real driving speed and other information launched by the RFID tag reader installed to the side of the road, and finally through the network information is transmitted to the control center and data storage and real-time display, in order to achieve the car is the actual speed monitoring and early warning function.
