Problems solved by technology

The disadvantage of this solution is that it is greatly affected by the distance of non-contact measurement. If the distance between the ear thermometer and the subject is far, it will not be able to provide accurate compensation.

Embodiment approach

[0021] The first implementation:

[0022] The first temperature t1 is compared with a preset first temperature threshold, and if the first temperature t1 is greater than the preset temperature threshold, for example, a temperature of 37° indicating that the biological body temperature may have a fever phenomenon, control all The display screen 4 displays the first temperature t1 in a second color, such as red, which is different from the conventional display color of the display screen 4 (for example, the conventional display color is the first color, such as green), to prompt the temperature measurer that the measurement device may exist inaccurate situation.

[0023] Second implementation:

[0024] comparing the second temperature t2 with a preset temperature threshold, and if the second temperature t2 is greater than the preset temperature threshold, controlling the display screen to display the second temperature in a second color, such as red t2, to remind the temperatu...

Abstract

The invention provides a temperature measuring device based on pressure correction. The temperature measuring device comprises a first temperature measuring port, a second temperature measuring port, at least one pressure sensor, a temperature measuring switch, a controller, a processor and an infrared temperature sensor. The first temperature measuring port is used for measuring the body temperature of a temperature measuring person holding the temperature measuring device; the second temperature measuring port is used for measuring the body temperature of a measured person; the processor is used for calculating a first temperature t1 measured by the first temperature measuring port and a second temperature t2 measured by the second temperature measuring port according to temperature data acquired by the infrared temperature sensor based on a temperature calculation instruction sent by the controller; the controller generates a corresponding temperature measurement control instruction based on the working state of the temperature measurement switch and the pressure value collected by the pressure sensor, and controls the processor to correct the first temperature t1 based on the pressure value collected by the pressure sensor. The measuring error of the temperature measuring device can be reduced, and the measuring accuracy is improved.

Description

technical field [0001] The invention relates to a temperature measuring device, in particular to a temperature measuring device which uses the temperature of the temperature measurer to correct the body temperature of the measured person. Background technique [0002] At present, the existing commonly used temperature measurement devices are generally infrared temperature measurement devices such as ear thermometers, forehead thermometers, and wrist thermometers. This infrared temperature measurement device has the advantages of fast measurement speed, no direct contact between the device itself and the subject, and no pollution to the environment, but it is extremely susceptible to external factors (such as light, measurement distance, ambient temperature, and external heat sources, etc.) The temperature measurement is inaccurate due to the influence. [0003] One way to solve this problem is to use external black body radiation calibration to solve the inaccurate measurem...
