The invention discloses a control method and device of air supply of an air conditioner. The method comprises the steps of obtaining the apparent temperature of a user in the acting space of the air conditioner, controlling the air conditioner to enter the working mode corresponding to the apparent temperature, and controlling horizontal wind guide bars to supply air according to the wind guide angle corresponding to the working mode, wherein the working mode comprises the modes of user alignment air supply or user avoidance air supply; starting a camera device for acquiring an image in the acting space of the air conditioner as a first image, and starting an infrared device for acquiring a heat source image in the acting space of the air conditioner as a second image; obtaining a wind guide target angle of vertical wind guide bars according to the first image and the second image; and adjusting the wind guide angle of the vertical wind guide bars according to the wind guide target angle, so as to control the air conditioner to align to or avoid the user to supply air. According to the control method and the control device, the intelligent degree of air supply control of the air conditioner is improved, the control accuracy of air supply of the air conditioner is improved, and the comfort of the user using the air conditioner is improved.

The invention belongs to the field of household appliances and particularly relates to an air sweeping control method and control system for an air conditioner. The air sweeping control method for the air conditioner comprises the steps as follows: the change rate TA of apparent temperature felt by a human body is acquired, and whether TA is plus or minus is judged; when TA is minus, whether the absolute value of TA is larger than a first preset threshold value TS1 is judged, and if yes, an air sweeping angle is controlled and adjusted to enable air to avoid the human body; when TA is plus, whether TA is larger than a second preset threshold value TS2 is judged, and if yes, the air sweeping angle is controlled and adjusted to enable air to be supplied towards the human body. According to the scheme, whether air sweeps towards a person or leaves the person is judged by detecting the change rate TA of the apparent temperature felt by the human body, so that targeted adjustment is performed on the air sweeping of the air conditioner according to the real-time change of the apparent temperature felt by a user, and the air leaves the human body after the human body is blown to be cold when the air blows towards the person; the air can come back automatically after avoiding the person for a period of time, automatic adjustment is realized, and the control accuracy and the comfort of the user can be improved.

The invention provides a system and a method for measuring the emissivity of the surface of an animal body. The system comprises a box body, a black body, a moving heat source and an infrared detection device. The infrared detection device takes a first thermal infrared image of a to-be-measured part of a to-be-measured animal body before heating and a second thermal infrared image of the black body before heating inside the box body, and takes a third thermal infrared image of the to-be-measured part of the to-be-measured animal body after heating through the moving heat source and a fourth thermal infrared image of the black body after heating through the moving heat source; the corresponding apparent temperatures of the to-be-measured part of the to-be-measured animal body before heating are calculated sequentially according to the thermal infrared images; and the emissivity of the surface of the to-be-measured part of the to-be-measured animal body is acquired through calculation according to the corresponding apparent temperatures. According to the invention, the emissivity of the surface of the to-be-measured animal body can be automatically output only by taking the thermal infrared images before and after heating. Therefore, measurement can be completed quickly.

The invention discloses a temperature reproducing method and a temperature reproducing device capable of sensing continuously. The method comprises the following steps of: a, changing the temperature from an initial temperature to a first temperature value in a heat sensation perception temperature interval at a first speed, and keeping the first temperature value for a while from a moment when the temperature reaches the first temperature value; b, stopping heating; c, when the temperature drops to a second temperature value in the heat sensation perception temperature interval, controlling the temperature to reach the first temperature value once again; and d, repeating steps b to c. Due to the adoption of the temperature reproducing method and the temperature reproducing device, a human body can keep sensitivity to cold sensation and heat sensation for a long time, the continuous temperature sensation reproducing time of a temperature sensation reproducing and expressing device is prolonged, the energy consumption of temperature sensation reproducing and expressing device is lowered, and the working time of the temperature sensation reproducing and expressing device is prolonged on the premise of limited energy resource; and temperature sensation expression of different information can be realized by controlling the intensities of the cold sensation and the heat sensation and alternative reproducing of the cold sensation and the heat sensation.
