基于射频识别技术的出租车防伪管理系统的设计与实现

综合运用2.45GHz有源射频识别(RFID)射频识别技术、信息处理技术、通用分组无线业务(GPRS)通信技术、全球定位系统(GPS)定位技术、移动计算与网络技术，设计了出租车防伪管理系统软硬件架构，开发出2.45GHz有源标签和具有识别、定位导航、移动通信功能于一体的信息终端。同时，在分析系统应用模式的基础上，开发出系统上层应用软件。搭建的应用系统测试结果表明：该系统超低功耗工作，标签峰值电流仅2mA；数据实时性高，传输平均延时小于4s；RFID感知终端有效识读距离达到110m，并能同时识读不少于150个标签。

Design and implementation of taxi anti-counterfeiting management system based on radio frequency identification technique

Taking comprehensive use of 2.45GHz active Radio Frequency Identification (RFID) technique, information processing technology, wireless communication technology of General Packet Radio Service (GPRS), Global Positioning System (GPS) technique, mobile computing and network technology, this paper designed the software and hardware structure of the taxi anti-counterfeiting management system, developed the 2.45GHz active tags and information terminals with the functions of recognition, orientation navigation and mobile communication. Meanwhile, on the basis of the analysis of the main application models, it developed the upper application software of the system. By setting up the application system and testing, the results show that the system can work with ultra-low power, the peak current is only 2mA; And the data transmit in real-time while delaying less than 4 seconds; Also the identifiable distance of the RFID terminal is about 110m and it can read no less than 150 tags at the same time.
