多协议超高频RFID读写器设计

摘要

为解决同一台射频识别读写器不能同时读取满足 ISO18000‐6C标准以及自主协议标准的电子标签的问题，采用FPGA （Xilinx Spartan6 XC6SLX16）＋ARM （STM32F407）的方案实现读写器的基带部分。用 FPGA 实现两种协议的物理层， A RM实现两种协议的协议层，使同一台读写器可用来读取两种协议的标签。在不增加硬件成本的前提下，该方案拓宽了读写器的使用范围，节约了资源。%To solve the problem that a radio frequency identification (RFID) reader can not read ISO18000‐6C tags and inde‐pendent protocol tags at the same time ,a FPGA (Xilinx Spartan6 XC6SLX16) and an ARM (STM32F407) were used to realize the baseband part of reader .FPGA was used to realize the physical layer ,and ARM was used to realize the protocol layer .The range of RFID application is broadened without increasing the cost of hardware ,the resources are saved .
