摘要
基于光电技术在输送线场景下对射频识别(RFID)动态性能进行了研究。利用激光测距技术设计了RFID动态识读距离测试系统,该系统可对单标签、多标签系统进行间接测距,以及可实现RFID标签识读距离和识读率的全自动测量。分别对单标签与多标签系统进行了动态性能测试,对测试结果进行了比对分析。结果显示,在单标签测试中,传送带的材质直接影响RFID标签的动态识读性能;而在多标签测试中,RFID标签的动态识读距离随标签数量的增加而减小,系统能够准确地检测出碰撞标签。
Abstract
The dynamic performance of radio frequency identification (RFID) under transportation line based on photoelectric technology is investigated. By the laser ranging technology, a testing system is designed to measure the dynamic reading distance of RFID. The reading distance of single-tag or multi-tag system can be measured indirectly, and the automatic measurement to the reading distance and literacy rate of RFID tags is realized. The single-tag and the multi-tag systems are respectively tested for their dynamic performances and the testing results are compared and analyzed. The results show that, in the process of testing the single-tag system, the dynamic reading performance of RFID tags is directly influenced by the material quality of conveyor belts. In contrast, in the process of testing the multi-tag system, the dynamic reading range of RFID tags decreases with the increase of the number of tags, and the collision tag can be detected accurately.
