Fig. 3 is a schematic flow chart of the method for controlling an air conditioner according to the present application, in which, when the air conditioner is installed, a face image is uploaded through an information base corresponding to the air conditioner, and the average temperature of the forehead of the human body corresponding to morning, noon and evening is detected and collected by using a temperature detection device as a reference (morning period: 0-9; noon period: 9.
After the people sensing mode is started, the main board supplies power for the image acquisition device and the temperature detection device. Preferably, the image acquisition device is a face recognition camera device, the temperature detection device is an infrared temperature detection device, and after a human body enters a face recognition scanning range, face information is collected:
1. when the number of people in the house is less than or equal to 2 people, the people sensing mode is automatically started;
2. when the number of people in the room is more than 2 or no people in the detection room is detected, the people sensing mode is not started, and the common mode is used for blowing.
The working mode when the number of people in the house is less than or equal to 2 people is as follows:
because the body temperature of the human body is different in different time periods in the morning, the noon and the evening, the temperature recorded by the human body in the information base is called out according to the real-time. Transmitting this information to an information processing module in the motherboard:
the detection number is 1 person: the temperature of the human body is recorded as T 0 When infrared temperature is detected, the real-time body temperature T is measured 1 >T 0 When the temperature is higher than the preset temperature +0.5 ℃ (the preset temperature), the user can be reminded by voice that the body temperature is slightly higher when the body temperature is relatively flat, medicine taking or medical treatment is recommended, and the user needs to confirm that the air conditioner can be started after the user needs to take the medicine again. When the body temperature satisfies T 1 <T 0 When the temperature is +0.5 ℃ (preset temperature), the human sensing mode is automatically started, and the indoor environment temperature is detected to be T through the inner temperature sensing bag 2 Setting the temperature T 3 ＝T 1 /3+T 2 /2。
Realize "parcel and feel" air-out mode: when the infrared temperature detection device detects an individual corresponding to face recognition, the maximum distance temperature in the scanning projection direction, the maximum distance temperature in the left direction and the maximum distance temperature in the right direction corresponding to the individual and the indoor environment temperature are detectedWhen the temperature difference exceeds 3 ℃, the three points are positioned by a rectangle formed by connecting the three points with the horizontal line and the vertical line, as shown in figure 4. And the positioning information is processed through the inner machine mainboard, so that signals are sent to the stepping motors at the two first tuyere 11 and the second tuyere 12, namely the stepping motors in the left direction, the lower direction and the right direction drive the air deflector to rotate to a position, the point position at the lower left corner of the infrared scanning is set as an O (0, 0) coordinate, and the coordinates of the human body position in fig. 4 are A (x) coordinates respectively 1 ，y 1 )、B(x 2 ，y 2 )、C(x 3 ，y 3 ) Because the air conditioner and the human body coordinate are placed in a mirror surface mode, the straight line X corresponding to the leftmost angle of air outlet of the air outlet vertical air deflector on the right side of the air conditioner 1 ＝x 1 The most upper wind sweeping range of the wind sweeping blades is Y 1 ＝y 3 As in fig. 4; similarly, straight line X corresponding to the rightmost angle of air outlet of vertical air deflector with left air outlet 2 ＝x 2 The most upper wind sweeping range of the wind sweeping blades is Y 2 ＝y 3 (ii) a Straight line Y corresponding to the lowest angle of air outlet of lower air outlet horizontal air deflector 3 ＝y 3 The wind sweeping range D of the wind sweeping blade needs to satisfy X 1 ，X 2 ]E.g. D, the sweep range includes the range between the left and right boundaries of the human body.
(II) the number of detected people is 2: at the three-side air outlet, the air deflector and the air sweeping blade on each side are divided into two parts and are controlled by an independent stepping motor. As shown in fig. 2, P1 (the first air sweeping component 40), P2 (the second air sweeping component 50) and P3 (the first air sweeping component 40) rotate corresponding to the first human body, and Q1 (the first air sweeping component 40), Q2 (the second air sweeping component 50) and Q3 (the first air sweeping component 40) rotate corresponding to the second human body, and the movement manner thereof is the same as the air outlet manner of the "wrapping feeling". Its set temperature T 4 ＝T’/3+T 2 /2，T’＝T Person 1 +T Person 2 Wherein T is Person 1 、T Person 2 And recording the temperatures of the human body I and the human body II in real time respectively.
In this embodiment, at three air outlets of the two first air outlets 11 and the second air outlet 12, the air deflector and the air sweeping blade on each side are equally divided into two parts and controlled by an independent stepping motor, so that when the number of people in the face recognition range and the infrared scanning range is within two people, the air outlet mode of the human body with the wrapping feeling can be realized respectively.
(III) the number of detected people is 0 or more than 2 people: the human sensing mode is not started, and the original blowing mode is used for adjustment.
Specifically, in another embodiment of the present application, the first fan units 20 are all provided with cross-flow blades, and the stepping motors corresponding to the first fan units 20 individually control the cross-flow blades, so that the contact surfaces with the floor, the bed body, the sofa, etc. are arranged below the human body, and thus, no air needs to be swept to the contact surfaces. The face recognition camera device and the infrared temperature detection device are vertically arranged at the middle lower part of the panel, the range of the face recognition camera device and the infrared temperature detection device can cover 120 degrees, and the detection of all human bodies in a room can be met by considering that the installation position of the air conditioner is the top of a corner of the room. Through being provided with temperature-detecting device and increasing infrared temperature detection function, the detectable human body surface temperature has increased face identification and has collected human information module through being provided with image acquisition device, collects different human respective average body temperatures behind the accessible face identification, calculates human body most comfortable body temperature through infrared temperature detection real-time body temperature after to realize the optimum air-out temperature. Through the air outlet structure of the air conditioner and the corresponding control mode, the wrapping feeling can be realized.
