| 摘 要： | 超高频RFID标签一致性直接影响RFID系统中采集数据的识别率和准确率。采用接收信号强度指示RSSI(Received Signal Strength Indicator)技术及数理统计,采集标签反射信号强度,设定标准差阈值,作为标签一致性检测参数。研制弯折偶极子近场天线,实现0.1 mm近距离标签识读。利用屏蔽效应,在全自动卷筒式RFID标签套装上设置打点标识机构,对标签批量标记,可实现对柔性超高频RFID标签的高速、批量一致性检测。

| Abstract: | The conformity of UHF RFID tags directly affects the recognition rate and accurate rate of data acquisition in a RFID system.We used the RSSI(Received Signal Strength Indicator) technique and mathematical statistics to collect reflected signal strength of tags and set the standard deviation threshold as parameters for tag conformity detection.We also developed the bending dipole near field antenna to read RFID tags in 0.1 mm distance.Using shielding effect,we set a dotting identification device on full automatic reel-type RFID tag sets and marked them in batch to achieve high speed conformity detection of flexible UHF RFID tags. |
