摘要
设计基于射频识别(Radio Frequency Identification,RFID)的智能卡阅读器,在标签阅读和物资管理中具有重要的应用价值。传统的RFID智能卡阅读器设计采用单频收发转换格式,无法有效满足多源多格式的标签阅读功能,提出一种支持多频多格式的RFID智能卡阅读器设计方法。首先进行系统模型总体设计,包括了RFID智能卡数据感知系统、阅读器驱动器和射频标签执行器系统、以及控制中心单元等子系统组成。采用RFID射频中间件技术实现标签阅读,考虑RFID智能卡阅读器的安全性,增加了硬件加密模块。为了实现多频多格式读写识别,在读写器的频段上进行标签的冲突重整。然后设计硬件电路,实现整个RFID智能卡阅读器的智能设计。系统仿真实验结果表明,采用该方法设计的RFID智能卡阅读器性能优越,对标签阅读的吞吐性能较好。
The design of the smart card reader based on Frequency Identification Radio （RFID） is of great value in the label reading and material management. Traditional RFID smart card reader is designed with single frequency duplexer format and cannot effectively meet the multi-source and multi format of label reading function, put forward a multi format support for the multi frequency RFID smart card reader design method. Firstly, the overall design of the system model, including the RFID smart card data sensing system, reader driver and RF tag execution system, and a control center unit subsystem composition. RFID radio frequency middleware technology is adopted to realize the tag reading, and the security of the RFID smart card reader is considered, and the hardware encryption module is added, in order to realize the multi frequency and multi format read and write recognition, the conflict of the label is carried out in the frequency band of the reader. Then design the hardware circuit, realize the whole RFID smart card reader＇ s intelligent design. System simulation experiments show that the proposed method is superior to the RFID smart card reader, and the performance of the proposed method is better.
