中文摘要：
针对目前的RFID系统性能优化问题,提出了一种确定标签优选位置的测试方法,通过这种方式来优化被动式超高频RFID系统的应用性能。首先搭建了较为理想的测试环境,然后改变标签在货箱上的贴附位置,并对每一个贴附位置沿固定方向改变货箱与天线的相对距离,接着对每一个距离测试标签的读取率。通过这种实验方法,来研究标签不同的贴附位置的读取率随着货箱与天线之间距离的变化规律,进而得出一个确定RFID标签优选位置的一般性结论。该方法操作简单,实用性强,可以为RFID系统的优化提供指导性建议。
英文摘要：
For performance optimization of a passive UHF RFID system,a test method that optimizes tag position is proposed. Firstly,a relative more ideal test environment has been built. And then,for each tag position attached on the container,change the distance between the container and the antenna along a fixed direction. After that,for each distance,test label read rates. In this way,the authors have studied the read rate trend with the change of distance between the antenna and container. And thus come to general conclusions to determine preferred locations of RFID tags. The experiment results show the method is easy and practical,and can provide good advices for deploying RFID systems.
