Problems solved by technology

[0003] When measuring body temperature, it is necessary to hold the infrared thermometer in hand and keep it as still as possible. Shaking during the measurement will affect the measurement results. In this way, there are certain requirements for the measurement operator, which also limits the range of operation and use of the infrared thermometer.

Embodiment Construction

[0019] A temperature measurement method based on displacement detection switching calculation, including a thermometer, and a displacement detection unit for detecting the position change of the thermometer; when the displacement detection unit feeds back that the thermometer is in a static state, then use Point measurement body temperature calculation method A is used to calculate and obtain the body temperature value; when the displacement detection unit feeds back that the thermometer is in a moving state, the scanning measurement body temperature calculation method B is used to calculate and obtain the body temperature value.

[0020] Usually, the displacement detection unit is set in the thermometer. There is a calculation unit in the thermometer, and the spot temperature calculation method A and the scanning measurement body temperature calculation method B are calculation formulas stored in the calculation unit respectively. The thermometer has an infrared temperature m...

Abstract

The invention discloses a temperature measuring method based on displacement detection switching calculation, which comprises a temperature measuring instrument, and a displacement detecting unit usedfor detecting changes of a position of the temperature measuring instrument; when the displacement detecting unit feeds back that the temperature measuring instrument is in a static state, a body temperature value is obtained through calculation by adopting a spot measurement body temperature calculation method A; and when the displacement detecting unit feeds back that the temperature measuringinstrument is in a moving state, a body temperature value is obtained through calculation by adopting a scanning measurement body temperature calculation method B. Therefore, the more precise body temperature value can be obtained, at the same time, the temperature measurement operation is simpler and more convenient, the temperature measurement operation requirements are reduced, and the practicability is high.

Description

technical field [0001] The invention relates to the technology in the field of body temperature measurement, in particular to a temperature measurement method based on displacement detection switching calculation. Background technique [0002] Infrared thermometer temperature measurement is to convert the radiation energy of the infrared rays emitted by the measured object into electrical signals. The size of the infrared radiation energy is related to the temperature of the object itself. According to the size of the converted electrical signal, the object’s temperature can be determined. temperature. [0003] When measuring body temperature, it is necessary to keep the infrared thermometer in hand as still as possible. Shaking during measurement will affect the measurement results. In this way, there are certain requirements for the measurement operator, and the scope of operation and use of the infrared thermometer is also limited. [0004] Therefore, in the present inve...
