摘　　要：设计并提出一种超高频射频识别系统读写器设计的新方案。该读写器采用IntelR1000收发器芯片、W78E365微控器，符合ISO18000-6C和EPC global Gen2标准，工作频率为860-960MHz，读写距离在2～10m之间。同时给出读写器硬件系统的组成和软件工作流程，并针对同时读取多张卡的情况进行分析，实现了防冲突算法。该读写器支持SSB-ASK和DSB-ASK双重调制方式，可根据需要改变使用天线的单、双模式。The design proposed in a new plan of the readerwriter in UHF RFID system. This reader - writer uses Intel R1000 transceiver chip,and W78E365 micro controller chip, which conforms to IS（3 18000 - 6C and EPC global Gen 2 standards. The operating frequency is 860~960 MHz, reader- writer distance is between 2~ 10 m. Then to provide the hardware configuration and the software flow of the system. Finally to analyze the situation when multiple cards are to be read, design and realize practical anti - collision arithmetic in the system. The reader- writer supports SSB- ASK and DSB- ASK double modulation, according to the actual situation to change the mode of single and dual antenna.
