This paper presents the use of radio-frequency identification (RFID) technology for the real-time remote monitoring of body temperature, while an associated program can determine the location of the body carrying the respective sensor. The RFID chip's internal integrated temperature sensor is used for both the human-body temperature detection and as a measurement device, while using radio-frequency communication to broadcast the temperature information. The adopted RFID location technology makes use of reference tags together with a nearest neighbor localization algorithm and a multiple-antenna time-division multiplexing location system. A graphical user interface (GUI) was developed for collecting temperature and location data for the data fusion by using RFID protocols. With a puppy as test object, temperature detection and localization experiments were carried out. The measured results show that the applied method, when using a mercury thermometer for comparison in terms of measuring the temperature of the dog, has a good consistency, with an average temperature error of 0.283 °C. When using the associated program over the area of 12.25 m2, the average location error is of 0.461 m, which verifies the feasibility of the sensor-carrier location by using the proposed program.
本文介绍了利用射频识别（RFID）技术对体温进行实时远程监测，同时一个相关程序能够确定携带相应传感器的身体的位置。RFID芯片内部的集成温度传感器既用于人体温度检测，又作为测量设备，同时利用射频通信来广播温度信息。所采用的RFID定位技术结合参考标签、最近邻定位算法和多天线时分复用定位系统。开发了一个图形用户界面（GUI），用于通过使用RFID协议收集温度和位置数据以进行数据融合。以一只小狗为测试对象，进行了温度检测和定位实验。测量结果表明，在测量狗的体温方面，与使用水银温度计相比，所应用的方法具有良好的一致性，平均温度误差为0.283℃。在12.25平方米的区域内使用相关程序时，平均位置误差为0.461米，这验证了使用所提出的程序对传感器载体进行定位的可行性。
