基于射频识别技术的电力一二次融合测温系统

Primary and Secondary Fusion Temperature Measurement System Based on RFID Technology

目前用在一次设备上的测温手段存在诸多局限,导致其难以用在一二次融合设备中。将基于射频识别技术(RFID)的温度传感器应用于一二次融合成套设备中,设计了RFID的一二次融合测温系统。利用RFID无需布线、无线传输的优点,将经过特殊结构设计的RFID传感器加入一次设备中,减少了布线,弱化了一二次分界。测试结果表明:相比于其他传统温度监测方法,基于RFID温度标签的温度监测具有能够身份识别、测温节点体积小、成本低和寿命长等优点。

The existing temperature measurement methods used in primary equipment have many limitations,hence difficult to be used in primary and secondary fusion equipment.The radio frequency identification(RFID)temperature sensor is applied to the primary and secondary fusion equipment,and the primary and secondary fusion temperature measurement system is designed based on RFID technology.Such advantages of RFID as no wiring and wireless transmission,the RFID sensor with special structure design is added to the primary equipment,which reduces wiring and weakens the primary-secondary boundary.The test results show that compared with other traditional temperature monitoring methods,the temperature monitoring based on RFID temperature tag has the advantages of identity identification,small size of temperature measurement node,low cost and long service life.
