The air conditioner control apparatus 100 includes at least one software function module that may be stored in the memory 22 in the form of software or firmware (firmware) or solidified in an Operating System (OS) of the air conditioner 20.

The millimeter wave radar 24 is a radar whose operating frequency band is the millimeter wave band, and the principle of ranging is the same as that of a general radar, that is, radio waves (radar waves) are transmitted, then echoes are received, and the position data of a target is measured according to the time difference between transmission and reception. Millimeter-Wave (MMW) refers to electromagnetic waves with a length of 1-10 mm, and the corresponding frequency range is 30-300 GHz. According to the wave propagation theory, the higher the frequency, the shorter the wavelength, the higher the resolution, and the stronger the penetration ability, but the larger the loss in the propagation process, the shorter the transmission distance; in contrast, the lower the frequency, the longer the wavelength, the stronger the diffraction power, and the further the transmission distance. Compared with microwaves, the millimeter waves have high resolution, good directivity, strong anti-interference capability and good detection performance; compared with infrared, the millimeter wave has the advantages of small atmospheric attenuation, better penetrability to smoke dust and small influence by weather; these traits determine the ability of millimeter-wave radar to operate around the clock of the day.
On the basis of the air conditioner 20 shown in fig. 2, a possible implementation manner of an air conditioner control method is given below, specifically, fig. 3 is a schematic flow chart of the air conditioner control method provided by the present invention, and please refer to fig. 3, the air conditioner control method includes:
and step S110, when the human body is detected to be in a motion state, obtaining the motion times of the human body within a preset time length through a millimeter wave radar.
In this embodiment, whether the human body is in a motion state can be detected by the millimeter wave radar 24, for example, whether the user walks on the treadmill for exercise, the transmitting module of the millimeter wave radar 24 can be controlled to continuously transmit electromagnetic waves, the detected target (for example, the human body) generates an echo, the receiving module of the millimeter wave radar 24 receives the echo signal, and if the received echo signal changes, the human body is determined to be in the motion state.
In this embodiment, when it is detected that the human body is in a motion state, for example, the user exercises on the treadmill, the current motion state of the user, for example, jogging, fast walking, jogging, fast running, etc., can be determined by the motion speed of the human body, and thus the operation state of the air conditioner 20 can be adjusted according to the current motion state of the user. However, when the user exercises on the treadmill, the user does not move back and forth with a large frequency, but mainly moves up and down, so the air conditioner 20 cannot directly detect the movement speed of the human body through the millimeter wave radar 24, based on this, the transmitting module of the millimeter wave radar 24 can be controlled to transmit electromagnetic waves, and the receiving module of the millimeter wave radar 24 receives the echo signal returned by the human body, so as to obtain the number of echo signals within a preset time duration (e.g., 1 minute), and the number of echo signals is used as the number of times of up and down movement of the human body within the preset time duration (e.g., 1 minute), so as to determine the movement speed of the human body according to the number of times.
As an embodiment, referring to fig. 4 on the basis of fig. 3, step S110 may include:
and a substep S1101 of sending a detection signal through a sending module of the millimeter wave radar and receiving an echo signal returned by the human body through a receiving module of the millimeter wave radar.
In this embodiment, it is found through research that the moving speed of the human waist is closest to the actual moving speed of the human body, and therefore, the transmitting module of the millimeter wave radar 24 may be controlled to transmit a detection signal to the human waist, and the receiving module of the millimeter wave radar may receive a returned echo signal.
And a substep S1102, counting the number of echo signals received within a preset time period, and taking the number of echo signals as the number of times of movement.
In the present embodiment, the number of echo signals received within a preset time period (e.g., 1 minute) is counted, and the number of echo signals is taken as the number of movements of the human body within the preset time period (e.g., 1 minute).
And step S120, determining the movement speed of the human body according to the movement times of the human body within the preset time length.
In the present embodiment, the frequency change of the millimeter wave radar 24 and the relative speed of the air conditioner 20 and the user are closely related to each other by the doppler effect, and the relative movement speed of the user and the air conditioner 20 can be known from the change of the frequency of the millimeter wave reflected back. That is, the movement speed of the human body may be determined according to the number of movements of the human body within a preset time period (e.g., 1 minute), and the preset time period may be flexibly set by the user according to the actual situation, which is not limited herein.
The Chinese family health big data report published in 2018 shows that the average height of Chinese men is 1.67 meters, the average height of women is 1.55 meters, and the user can set the treadmill according to the running ability of each person in the following four modes, and the corresponding speeds are listed:
slow walking: 3-6 km/h is 0.83-1.66 m/s;
fast walking: 6-8 km/h is 1.66-2.22 m/s;
jogging: 8-10 km/h is 2.22-2.78 m/s;
fast running: the speed of 10-12 km/h is 2.78-3.33 m/s.
Meanwhile, the distance between the front foot and the rear foot of a normal adult is 0.6m, 2 steps are needed when the adult uniformly walks within 1s for 1.2m, 3 steps are needed when the adult walks for 1.8m, 4 steps are needed when the adult walks for 2.4m, 5 steps are needed when the adult walks for 3m, and the waist of the human body needs to be moved for 1 time when the adult walks for one step. Therefore, the number of movements of the human body per second (e.g., 2 times) is calculated according to the number of movements of the human body (e.g., 120 times) within a preset time period (e.g., 1 minute), and then the movement speed of the human body is determined according to the number of movements of the human body per second (e.g., 2 times), for example:
if the number of times of the human body movement per second is 2, which means that the user approximately travels 1.2m, the human body movement speed is 1.2 m/s;
if the number of times of movement of the human body per second is 3, which means that the user approximately travels 1.8m, the movement speed of the human body is 1.8 m/s;
if the number of times of movement of the human body per second is 4, which means that the user approximately travels 2.4m, the movement speed of the human body is 2.4 m/s;
if the number of times of movement of the human body per second is 5, which means that the user travels about 3m, the movement speed of the human body is 3m/s, and so on.
As an embodiment, referring to fig. 5 on the basis of fig. 3, step S120 may include:
and a substep S1201, taking the number of times of the human body movement within the preset time period as the number of steps of the human body within the preset time period.
In the present embodiment, the number of movements (e.g., 120) of the human body for a preset time period (e.g., 1 minute) is taken as the number of steps (e.g., 120 steps) of the human body for the preset time period (e.g., 1 minute).
And a substep S1202 of calculating the movement speed of the human body according to the step number of the human body in the preset time period and the prestored single step distance.
In this embodiment, the single step distance is a distance of one step, for example, 0.6m, which is taken by a normal adult, and the number of steps (for example, 120 steps) of the human body per second can be obtained according to a preset time period (for example, 1 minute), and the movement speed (for example, 1.2m/s) of the human body can be calculated by combining the single step distance.
And step S130, calculating the exercise oxygen consumption of the human body according to the exercise speed.
In this embodiment, after the exercise speed of the human body is calculated, the exercise oxygen consumption of the human body can be further calculated based on the exercise speed. The exercise oxygen consumption of the human body can be calculated by Metabolic Equivalent (MET), which is an important index representing a relative energy metabolism level and exercise intensity, and expresses the relative energy metabolism level in various exercises based on the energy consumption in sedentary sitting, for example, the MET value of a human in a sedentary sitting state is 1 and the MET value of a human in a rapid running state is 5. Therefore, the MET value corresponding to the movement speed can be obtained from the calculated movement speed of the human body, and the movement oxygen consumption of the human body can be calculated from the MET value, for example:
if the moving speed is 3-6 km/h, defining the moving speed as a slow walking mode, and the corresponding MET value is 2;
if the moving speed is V6-8 km/h, the moving speed is defined as a fast walking mode, and the corresponding MET value is 3;
if the motion speed is 8-10 km/h, the motor is defined as a jogging mode, and the corresponding MET value is 4;
if the moving speed is V10-12 km/h, the running mode is defined, and the corresponding MET value is 5.
As an embodiment, referring to fig. 6 on the basis of fig. 3, step S130 may include:
in the substep S1301, a target speed interval matching the movement speed is determined among the plurality of speed intervals.
In the present embodiment, the air conditioner 20 stores a plurality of speed intervals and MET values corresponding to each speed interval in advance, as shown in table 1 below:
TABLE 1 speed interval and MET value
| Speed interval | MET value |
| 3～6km/h | 2 |
| 6～8km/h | 3 |
| 8～10km/h | 4 |
| 10～12km/h | 5 |
According to the moving speed (e.g., 1.2m/S) of the human body calculated in step S120, a target speed section (e.g., 3-6 km/h) matching the moving speed (e.g., 1.2m/S) is determined according to table 1.
In the sub-step S1302, a target MET value corresponding to the target speed interval is obtained.
In the present embodiment, according to Table 1, a target MET value (e.g., 2) corresponding to a target speed interval (e.g., 3-6 km/h) is obtained.
And a substep S1303 of calculating exercise oxygen consumption by using a preset formula Q ═ m × t × k 3.5ml/(kg · min), based on the body weight, the target MET value and the exercise time length stored in advance, wherein Q represents the exercise oxygen consumption, m represents the body weight, t represents the exercise time length, k represents the target MET value, k is 1,2,3 …, and 1MET is 3.5ml/(kg · min).
In this embodiment, the body weight of the user may be transmitted to the air conditioner 20 through an application program in the terminal 10 before the user starts exercise, for example, before walking on a treadmill for exercise. The exercise duration refers to a duration from the beginning of the exercise of the user to the current time, that is, a duration in which the air conditioner 20 operates in the exercise mode after the user starts the exercise mode of the air conditioner 20.
1MET is 3.5ml/(kg · min), 1MET roughly corresponding to the consumption of oxygen per minute when a person sits without any activity in a resting state, kMETs represents the consumption of oxygen k times higher than that in a resting state, for example, 5METs represents the consumption of oxygen 5 times higher than that in a resting state. For example, if the air conditioner 20 detects that the exercise speed of the human body is 7.5km/h after the exercise mode is operated for 5 minutes, the mode belongs to the fast walking mode, and if the weight of the user is 65kg, the exercise oxygen consumption is calculated as: 65 × 5 × 3 × 3.5 ═ 3412.5ml ═ 3.4125L.
And step S140, adjusting the running state of the air conditioner based on the movement oxygen consumption.
In this embodiment, after calculating the exercise oxygen consumption of the human body, the operation state of the air conditioner 20, that is, the air output, temperature, humidity, and the like of the air conditioner 20 can be adjusted by combining the exercise oxygen consumption of the human body, the current season, the current indoor humidity, and the like, so that the constant body temperature of the human body is 19 to 24% in summer, 17 to 22% in winter, and the relative humidity of the human body is 50 to 60%.
Specifically, firstly, the current exercise mode of the user can be determined according to exercise oxygen consumption, for example, taking exercise duration as 5 minutes, the person exercise oxygen consumption with weight of 65kg 1.1375-2.275L is in a slow walking mode, the person exercise oxygen consumption is 2.275-3.4125L is in a fast walking mode, the person exercise oxygen consumption is 3.4125-4.55L is in a slow running mode, and the person exercise oxygen consumption is 4.55-5.6875L is in a fast running mode; then, obtaining motion state parameters corresponding to the determined current motion mode, for example, the current motion mode is a fast walking mode, and the corresponding motion state parameters are secondary wind, the temperature is 22 ℃ and the like; then obtaining the current season and the current indoor humidity, and adjusting the motion state parameters according to the current season and the current indoor humidity, for example, if the current season is summer and the temperature in the motion state parameters is higher than 24 ℃, adjusting the indoor environment temperature to 24 ℃, and if the current season is winter and the temperature in the motion state parameters is lower than 17 ℃, controlling the indoor environment temperature to 17 ℃; if the detected indoor humidity is lower than 50%, adopting humidification treatment, and if the detected indoor humidity is higher than 60%, adopting dehumidification treatment; finally, the operation state of the air conditioner 20 is adjusted according to the adjusted motion state parameter.
As an embodiment, referring to fig. 7 on the basis of fig. 3, step S140 may include:
in sub-step S1401, a target oxygen consumption interval matching the kinetic oxygen consumption is determined among a plurality of oxygen consumption intervals.
