摘　　要：本文分析了读写器和标签之间的通信条件,通过配置无线收发芯片的寄存器可设定芯片的工作频率和传输速率,通过调整芯片外围匹配网络的元件参数达到与芯片的工作频率相匹配,并用软件编程实现所需的编解码方式和数据包格式,得到一种新型适应性强的RFID读写器的设计方案。The communication conditions between reader and tag are analyzed. The operating frequency and transmission rate are set by configuring the registers of wireless transceiver chip, parameters of the components in external matching network are adjusted so as to match with operating frequency of the chip, and the required encoding/decoding mode and packet format are realized by using software programming. Finally,a new adaptable RFID reader is designed.
