摘要
基于电子标签封装材料吸湿性对介电常数的影响和封装材料介电常数对电子标签超高频射频性能的影响,设计并制作了可测湿度的电网设备电子标签。在标签设计方面选取了具有较强吸湿性的尼龙材质作为封装材料和窄带宽的抗金属线型作为天线结构,在读写终端设计方面改进了获取电子标签激活灵敏度中心频点的功能。模拟应用湿度性能测试显示,可测湿度的电网设备电子标签测量的相对湿度与湿度计测量的相对湿度两者绝对差值平均是2.0%RH。该设计使电子标签带有传感器的功能,将标识和感知合二为一,基本满足相对湿度测量精度要求不高的应用需求。
There were two kinds of relations applied in humidity-functional grid asset radio frequency tag:the influence of moisture-absorption nylon on tag dielectric constant,and the influence of tag dielectric constant on tag radio frequency perfor‐mance.For tag design,it was used that moisture-absorption nylon on package material and narrow bandwidth design on RFID An‐tenna.Also,it was improved to get center frequency of tag activation sensitivity for read-write handsets.In the test of application simulation,the average absolute difference of relative humidity is 2.0%RH between humidity-functional grid asset radio fre‐quency tag and moisture meter.In this paper,humidity-functional grid asset radio frequency tag achieved to combine sensor func‐tion into electronic tag,and nearly can meet the requirement for appropriate measurement accuracy.
