摘要
带传感器的射频识别（RFID）电子标签是一种新的无线监测方法,为了研究将带传感器的RFID电子标签应用于变电站电气设备状态信息采集的可行性,以温度传感标签为例,根据带传感器的RFID电子标签技术原理与特点,对将带传感器的RFID标签应用于变电站电气设备状态信息采集进行了总体设计和具体设计,提出了实际应用对于标签的通信距离、标签类型等重要指标的要求。结果表明,变电站建议选择有源式RFID标签,通信距离应在50～150m之间;标签和阅读器的安装位置与数量需要统筹考虑,标签和阅读器安装时,应尽量避免有金属物体对其通信形成障碍;设备的安装高度越高、设备与金属环境的距离越远,其通信效果越好。
Radio frequency identification （RFID） tag with sensors is a novel method for monitoring electrical equipment online. Taking a RFID temperature sensor system as an example, we studied the feasibility of applying RFID sensors in information acquisition of electrical equipments in substation. Based on the working mechanism and features of RFID sensors, an overall and detailed design using RFID sensors to collect information of electrical equipment in substation was completed, thereby the demands from application on RFID sensors, such as communication distance and tag type, were proposed. The results reveal that, the active RF＇iD tags and the communication distance between 50 m and 150 m are recommended for substations. For tags and readers, both their installation position and number need to be taken into consideration： in the installation, we should avoid metal objects impeding the communication; the higher the devices are, the better the communication is.
