Problems solved by technology
[0003] In related technologies, the human body temperature value detected by the infrared human detection unit is usually greatly affected by the indoor ambient temperature and the distance between the person and the infrared human detection unit. The distance of the unit fluctuates, and the fluctuation does not follow a linear change pattern, which affects the accuracy of human body temperature detection and the control of the air conditioner, bringing bad experience to users

The invention provides an air conditioner. The preset first working condition of the air conditioner is the working condition meeting the indoor environment temperature threshold value condition and the distance threshold value condition, and a first mapping relation exists between the preset first working condition and the shell temperature calibration coefficient K1; when the indoor environment temperature value T1 and the distance L meet the first working condition, a shell temperature calibration coefficient K1 is obtained according to the first mapping relation; calculating a body surface temperature calibration value T3 in combination with the body surface temperature detection value T2 and the body surface temperature calibration coefficient K1; a second mapping relation exists between the preset body surface temperature threshold condition and the body surface temperature calibration coefficient K2; if the body surface temperature calibration value T3 meets the preset body surface temperature threshold condition, a body surface temperature calibration coefficient K2 is obtained through a second mapping relation; and the body surface temperature calibration value T3 and the body surface temperature calibration coefficient K2 are combined to calculate the in-vivo temperature T4. According to the air conditioner, by presetting the first mapping relation and the second mapping relation, the influence of distance and indoor environment temperature value measurement is reduced, the accuracy is high, and the measurement result is stable.
Description
technical field [0001] The invention relates to the technical field of household appliances, in particular to an air conditioner. Background technique [0002] At present, air conditioners are usually equipped with an infrared human-sensing detection unit to detect parameters such as the number, location, and body temperature of people. The high-resolution infrared human-sensing detection unit can also form an infrared image according to the detected temperature information, and can determine the detection object. The distance from the infrared human detection unit. [0003] In the related art, the human body temperature value detected by the infrared human sense detection unit is usually greatly affected by the indoor ambient temperature and the distance between the person and the infrared human sense detection unit. The distance of the unit fluctuates, and the fluctuation is not linear, which affects the accuracy of human body temperature detection, affects the control of...
