摘　　要：为适应复杂环境中RFID系统的使用,基于SAW标签的RFID系统弥补了传统基于IC标签的RFID系统易受环境干扰等缺点。介绍了识别SAW标签的RFID阅读器的系统设计方案,详细说明阅读器信号处理电路的设计过程,通过软件仿真与电路调试,验证了基于C8051F的SAW RFID阅读器设计可行性。信号处理电路具有结构简单,成本低廉等特点,有较好的应用价值。For the usage of RFID system in the orientation environment, The RFID system of SAW label is better than the RFID system of IC label which is Easily be subjected to environment interference. This paper introduced the system design of RFID Reader which used for identifies SAW label, elaborate on the electric circuit design of signal processing system, through simulation and debugging, verified the design of SAW RFID Reader based on C8051F is possibility. This signal processing system has a simple structure, low cost and better of applied value.
