一种测温标签、读写器及测温系统
摘要：
本发明涉及一种测温标签、读写器及测温系统，测温标签包括：第一天线以及测温芯片；第一天线与测温芯片相连接，用于接收读写器发送的能量信号，能量信号用于为测温标签提供电能；测温芯片对开关柜的铜排进行温度测量，形成反馈信号，将反馈信号传输至第一天线，其中，反馈信号包括测量后的开关柜的铜排的温度数据以及开关柜的铜排的标识；第一天线将反馈信号发送给读写器。本发明提供的测温标签、读写器及测温系统可以实现无源RFID测温，无需电池供电，测温芯片体积小，重量轻，抗干扰能力更强，增加测温芯片的使用寿命，满足现场应用需求。
摘要（英）：

The invention relates to a temperature measuring label, a reader-writer and a temperature measuring system; the temperature measuring label comprises a first antenna and a temperature measuring chip; the first antenna is connected with the temperature measuring chip so as to receive energy signals sent by the reader-receiver, and the energy signals are used for providing electric power for the temperature measuring label; the temperature measuring chip is used for measuring the temperature of copper bars of a switch cabinet, thus forming a feedback signal and sending the feedback signal to the first antenna; the feedback signal comprises measured temperature data of the copper bars of the switch cabinet and copper bar IDs of the switch cabinet; the first antenna is used for sending the feedback signal to the reader-receiver. The t temperature measuring label, reader-writer and the temperature measuring system can realize passive RFID temperature measurement with no power from the battery; the temperature measuring chip is small in size, light in weight, stronger in anti-interference capability, thus increasing the temperature measuring chip service life, and satisfying field application demands.
