Abstract
(EN)
In a body temperature measuring system, body temperature measurement with a temperature resolution of 0.01°C is implemented, and power consumption of a data reading device is reduced. A clinical thermometer of this invention is a body temperature measuring system including a body temperature tag (113) and a data reading device (101). A processing unit (115) of the body temperature tag (113) includes a power supply circuit, a semiconductor temperature sensor for detecting a band gap voltage, and a storage means for storing calibration data to calibrate the detected band gap voltage, and is configured to, upon activating the power supply circuit, send the detected band gap voltage via the antenna unit (114) together with the calibration data. The data reading device (101) includes an excitation means, and a sensing means for sensing a change in a magnetic field generated by excitation. The power level of the excitation means is changed upon sensing the change in the magnetic field.

Selon l'invention, dans un système de mesure de la température corporelle, on réalise une mesure de la température corporelle sur la base d'une résolution de température de 0,01 °C, et l'on effectue une réduction de l'énergie électrique consommée par un dispositif de lecture de données. Plus particulièrement, l'invention concerne un thermomètre clinique qui est un système de mesure de la température corporelle doté d'une étiquette de température corporelle (113) et d'un dispositif de lecture de données (101). Une unité de traitement (115) de l'étiquette de température corporelle (113) est dotée d'un circuit d'alimentation électrique, d'un capteur de température corporelle à semi-conducteur qui détecte une tension de largeur de bande interdite, et d'un dispositif de mémorisation qui mémorise des données d'étalonnage permettant d'étalonner la tension de largeur de bande interdite détectée. L'unité de traitement susmentionnée (115) est conçue de façon que la tension de largeur de bande interdite susmentionnée détectée conjointement avec le démarrage du circuit d'alimentation électrique susmentionné soit transmise, par le biais d'une unité d'antenne (114), conjointement avec les données d'étalonnage susmentionnées. Le dispositif de lecture de données (101) est doté d'un moyen d'excitation et d'un moyen de détection qui détecte un changement du champ magnétique provoqué par l'excitation. Le dispositif de lecture de données susmentionné (101) est caractérisé en ce que, lorsqu'un changement du champ magnétique est détecté, le niveau de puissance électrique des moyens d'excitation est modifié.
