摘　　要：射频识别（Radio Frequency Identification，RFID）系统动态性能检测是近年来物联网产品检测领域的研究热点，检测参数包括识别率和识读距离等。本文针对特殊非标RFID标签空中识别距离检测的迫切需求，提出一种高精度激光测距传感器与频谱分析仪组合的检测新方法，并设计研制了检测系统。实验表明，检测的声表面波RFID标签样品最大空中识别距离接近8m，同时，对RFID系统防碰撞能力开展了实验验证。在完成检测的同时，也同步验证了本文提出的检测方法的可行性和检测系统的有效性。The dynamic performance detection of RFID system is a focus in the area of the internet of things （IOT） product detection in recent years. The testing parameters include the identification rate as well as the identification range. In this paper, under the urgent need to detect the identification range, a novel method that is a combination of laser distance measuring sensor and spectrum analyzer is proposed. Meanwhile, the detection system is designed. Experimental results show that the maximal identification range of the sample of the tested SAW RFID tag reaches approximately 8 meters. Moreover, the anti - collision capability of the RFID sys- tem has been proved. Furthermore, the detection is completed and both the feasibility of this proposed method and the efficiency of the detection system are verified.
