Embodiment Construction

[0045] 1. Principle

[0046] In the present embodiment, the measurement of the surface temperature will be described by designating the measurement target position of the skin as the temperature measurement target, that is, the subject. In addition, there are two types of temperature measurement. That is, "calculation" of temperature and "estimation" of temperature. First, "calculation" will be explained, and then "guessing" will be explained.

[0047] 1-1. Principle of temperature calculation

[0048] figure 1 It is an explanatory diagram of the principle of temperature calculation in this embodiment. In this embodiment, if figure 1 As shown in (1), the surface temperature of the object to be measured is calculated by bringing the contact surface F of the base 100 into contact with the surface K of the object to be measured which is a temperature measurement object. It should be noted that the surface temperature is not measured by making the temperature sensor directly...

Abstract

A temperature measurement device and a temperature measurement method are provided. The temperature measurement device (100) includes: a first temperature sensor (11) and a second temperature sensor (12) that are provided at different positions in a base portion (100) that is in contact with a measurement subject; and a computation processing unit (300) configured to calculate a temperature of the measurement subject by using temperatures detected by the first temperature sensor (11) and the second temperature sensor (12). The computation processing unit (300) calculates the temperature of the measurement object by use of a heat budget relative coefficient representing the relative coefficient of the heat budget in the first temperature sensor (11) and the second temperature sensor (12) when the base portion (100) is allowed to contact with the measurement object, and by use of the detected temperature of the first temperature sensor (11) and the second temperature sensor (12).

Description

technical field [0001] The present invention relates to a temperature measuring device and the like for measuring the temperature of a subject. Background technique [0002] There are several ways to measure temperature. For example, as a known method, when the body to be measured is a human body, the body temperature measurement method can be to put a temperature sensor covered with a metal cover with good conductivity under the armpit, etc., and obtain the temperature measured by directly contacting the surface of the human body. Body temperature method (Patent Document 1), or a method of detecting the intensity of infrared rays emitted from the ear to obtain body temperature (Patent Document 2), etc. [0003] However, any measurement method has advantages and disadvantages. In measurement, it is necessary to select an appropriate measurement method for a variety of problems such as the environmental aspects of the measurement site, the measurement site to be measured, a...
