摘　　要：针对RFID标签抗金属干扰问题，提出一种闸门环境下金属对RFID标签识读性能影响的检测评估方法。通过构建基于光电传感系统的物联网应用，模拟使标签能够在金属物体表面正常工作的环境，改变标签在货箱上的贴附位置，并在最佳位置处沿固定方向改变标签与金属的相对距离，测试标签的动态识读距离。通过实验，研究标签的识读距离随着标签与金属相对距离的变化规律，分析并给出闸门环境下金属对RFID标签识读性能影响的重要结论。本文研究为RFID系统动态识读和抗金属干扰能力的提高提供有意义的研究参考。For the problem of RFID tag anti-metal interference, a test and evaluation method for the influence of metal on the reading performance of RFID tag under gate environment is presented. Firstly, we build test environment of IOT application based on the photoelectric sensor system, and simulate work environment to get the tag to and c work hange properly on the surface of a metal object; and then, we change the location where tag is attached the relative distance between the tag and metal along the fixed direction in the optimum location; finally, we test the dynamic reading distance of the tag. The rule that the reading distance of the tag varies with the relative distance between tag and metal is analyzed via experiments. Important conclusions are drawn that the reading performance of RFID tag is impacted by metal. This study provides valuable reference for the RFID system dynamic identification and the development of anti-metal interference ability.
