提出了一种自适应功率匹配算法

使得天线扫描范围内的多个标签都能在最佳测温功率下测温。测试结果表明:当温度标签与阅读器天线的距离分别为0.5

1.0

1.5 m时

测温误差小于±1℃。

Abstract

A temperature monitoring system based on passive UHF RFID temperature tag is designed. The system consists of self-designed passive UHF RFID tags

Speedway R220 commercial reader and a upper PC application software

the temperature monitoring system realizes object identification recognition

real-time temperature measurement and display function. In order to increase precision of temperature tag

an adapative power matching algorithm is proposed

which can make multiple tags within the antenna scan range work in optimum temperature measuring power. The test results show that when the distance between the tag and the reader is respectively0. 5 m

1. 0 m and 1. 5 m

the temperature measurement error is less than ± 1 ℃.
