step S10, detecting a user in a space where an air conditioner is located, and acquiring the distance between the user and the air conditioner;
in this embodiment, the execution main body is an air conditioner. The air conditioner is provided with at least two air outlets and counter-rotating fans corresponding to the air outlets, the counter-rotating fans are used for supplying air to the air outlets, the counter-rotating fans can be a first pair of cyclone machines and a second pair of cyclone machines, and the position of the first pair of cyclone machines is higher than that of the second pair of cyclone machines.
The pair of cyclone machines comprises two wind wheels, namely the first pair of cyclone machines comprises a first wind wheel and a second wind wheel, and the second pair of cyclone machines comprises a third wind wheel and a fourth wind wheel. The rotating speeds of the first wind wheel and the second wind wheel are controlled by the same motor, and the rotating speeds of the third wind wheel and the fourth wind wheel are controlled by the same motor. Or the rotating speeds of the first wind wheel and the second wind wheel are respectively controlled by different motors, for example, the rotating speed of the first wind wheel is controlled by the first motor, the rotating speed of the second wind wheel is controlled by the second motor, and the rotating speed of the first wind wheel and the rotating speed of the second wind wheel can be the same or different; the rotating speed of the third wind wheel is controlled by a third motor, the rotating speed of the fourth wind wheel is controlled by a fourth motor, and the rotating speed of the third wind wheel can be the same as or different from that of the fourth wind wheel. It should be noted that the rotation directions of the first wind wheel and the second wind wheel in the first pair of cyclones may be the same or different, and the rotation directions of the third wind wheel and the fourth wind wheel in the second pair of cyclones may be the same or different.
As shown in fig. 2, the principle of action on the cyclone is as follows: after the air current comes out from first wind wheel 1, the contrary direction of second wind wheel 2 is rotated and is given the contrary speed of circling around of air current to offset the partial speed of circling around of air current, and then reduced the ability to surrounding air drive, thereby can improve the air supply distance. As shown in fig. 3, the operating principle of the double-pair cyclone is as follows: by adjusting the rotation speed of the first pair of cyclones 10 and the rotation speed of the second pair of cyclones 20, different blowing distances can be achieved.
In this embodiment, the manner of obtaining the distance between the user and the air conditioner may be: and receiving a target air supply distance sent by the control terminal, and taking the target air supply distance as the distance between the user and the air conditioner. The user can select air supply gears, such as high gear, middle gear, low gear and the like, and different gears correspond to different air supply distances; the user may also select the air supply distance, such as 2 meters, 4 meters, 6 meters, etc., and thus the distance between the user and the air conditioner may be determined according to the gear selected by the user or the air supply distance selected by the user. Or, the distance between the user and the air conditioner is acquired through the distance detection device, that is, the user in the space where the air conditioner is located can be detected through equipment such as an infrared sensor and a radar sensor, and the distance between the user and the air conditioner can be acquired through equipment such as a radar sensor and a bluetooth sensor.
S20, acquiring the air supply distances of at least two counter-rotating fans according to the distances;
in this embodiment, the air supply distance of the at least two counter-rotating fans can be determined according to the distance between the user and the air conditioner. Specifically, when the user is a person, the distance between the user and the air conditioner may be used as the air supply distance of each pair of cyclone fans, for example, when the user is a person and the distance between the user and the air conditioner is 6 meters, the first pair of cyclones is started, the rotation speed of the first wind wheel is 500 rpm, the rotation speed of the second wind wheel is 400 rpm, the third wind wheel of the second pair of cyclones is started, and the rotation speed of the third wind wheel is 300 rpm.
When the user is a plurality of people, the distance between the user farthest from the air conditioner and the air conditioner can be used as the air supply distance of the first pair of cyclones, and the distance between the user closest to the air conditioner and the air conditioner can be used as the air supply distance of the second pair of cyclones, for example, when the user is two people and the distances between the user and the air conditioner are 2 meters and 6 meters respectively, the first pair of cyclones are responsible for supplying air to the user with the distance of 6 meters, the rotating speed of the first wind wheel is 500 rpm, the rotating speed of the second wind wheel is 400 rpm, the second pair of cyclones are responsible for supplying air to the user with the distance of 2 meters, the rotating speed of the third wind wheel is 100 rpm, and the rotating speed of the fourth wind wheel is 250 rpm. When the user is a plurality of users, an average value of distances between the plurality of users and the air conditioner may be calculated, and the average value may be used as the blowing distances of the first pair of cyclones and the second pair of cyclones.
And step S30, controlling the rotating speeds of the wind wheels of at least two counter-rotating fans according to the air supply distance.
In this embodiment, the correspondence between the air supply distance and the rotational speed of the wind wheel is preset. For example, when the users are four people and the distances between the users and the air conditioner are 2 meters, 2.5 meters, 4 meters and 6 meters respectively, the first pair of cyclones is responsible for supplying air to the users with the distance of 6 meters, the rotating speed of the first wind wheel is 500 rpm, the rotating speed of the second wind wheel is 400 rpm, the second pair of cyclones is responsible for supplying air to the users with the distance of 2 meters, the rotating speed of the third wind wheel is 100 rpm, and the rotating speed of the fourth wind wheel is 250 rpm.
And when the air supply distance is consistent, the opening number of the counter-rotating fans is different, and the rotating speeds of the wind wheels are different. The user can select the opened pair of cyclones, such as only opening the first pair of cyclones, only opening the second pair of cyclones, or simultaneously opening the first pair of cyclones and the second pair of cyclones. And further determining the rotating speed of the wind wheel in the wind wheel according to the counter-rotating fan which is selected to be started by a user.
It should be noted that the solution of the present embodiment realizes that the wind speed reaching the position of the user is greater than a preset value, wherein the preset value may be 0.3 m/s.
In the first embodiment, the distance between a user in the space where the air conditioner is located and the air conditioner is acquired, the air supply distance of at least two counter-rotating fans is acquired according to the distance, and the rotating speed of wind wheels of the at least two counter-rotating fans is controlled according to the air supply distance. Therefore, the air supply distances of the at least two counter-rotating fans are determined firstly, and the rotating speeds of the at least two counter-rotating fans are adjusted according to the determined air supply distances, so that the air conditioner supplies air based on different distances.
In a second embodiment, as shown in fig. 5, on the basis of the embodiment shown in fig. 4, the step of obtaining the air supply distances of the at least two counter-rotating fans according to the distance includes:
step S21, acquiring the number of users in the space where the air conditioner is located;
and step S22, determining the air supply distance of at least two counter-rotating fans according to the number of the users and the distance.
In this embodiment, the air supply distance of the at least two counter-rotating fans can be determined according to the distance between the user and the air conditioner. Specifically, when the user is a person, the distance between the user and the air conditioner may be used as the air supply distance of each pair of cyclone fans, for example, when the user is a person and the distance between the user and the air conditioner is 6 meters, the first pair of cyclones is started, the rotation speed of the first wind wheel is 500 rpm, the rotation speed of the second wind wheel is 400 rpm, the third wind wheel of the second pair of cyclones is started, and the rotation speed of the third wind wheel is 300 rpm.
When the user is a plurality of people, the distance between the user farthest from the air conditioner and the air conditioner can be used as the air supply distance of the first pair of cyclones, and the distance between the user closest to the air conditioner and the air conditioner can be used as the air supply distance of the second pair of cyclones, for example, when the user is two people and the distances between the user and the air conditioner are 2 meters and 6 meters respectively, the first pair of cyclones are responsible for supplying air to the user with the distance of 6 meters, the rotating speed of the first wind wheel is 500 rpm, the rotating speed of the second wind wheel is 400 rpm, the second pair of cyclones are responsible for supplying air to the user with the distance of 2 meters, the rotating speed of the third wind wheel is 100 rpm, and the rotating speed of the fourth wind wheel is 250 rpm. When the user is a plurality of users, an average value of distances between the plurality of users and the air conditioner may be calculated, and the average value may be used as the blowing distances of the first pair of cyclones and the second pair of cyclones. For example, when the user is four people and the distances between the user and the air conditioner are 2 meters, 3 meters, 5 meters and 6 meters, the first pair of cyclones and the second pair of cyclones both supply air according to the air supply distance of 4 meters.
In the second embodiment, the air supply distances of at least two counter-rotating fans are determined according to the number of users in the air conditioner acting space and the distance between the users and the air conditioner, so that accurate air supply is realized for different numbers of users.

step S222, taking a distance between a user farthest from the air conditioner and the air conditioner as an air supply distance of the first pair of cyclones, and taking a distance between a user closest to the air conditioner and the air conditioner as an air supply distance of the second pair of cyclones.
In this embodiment, when the user is a plurality of users, the distance between the user farthest from the air conditioner and the air conditioner may be used as the air blowing distance of the first pair of cyclones, and the distance between the user closest to the air conditioner and the air conditioner may be used as the air blowing distance of the second pair of cyclones. For example, when the users are two people and the distances between the users and the air conditioner are 2 meters and 6 meters respectively, the first pair of cyclones is responsible for supplying air to the users with the distance of 6 meters, the rotating speed of the first wind wheel is 500 rpm, the rotating speed of the second wind wheel is 400 rpm, the second pair of cyclones is responsible for supplying air to the users with the distance of 2 meters, the rotating speed of the third wind wheel is 100 rpm, and the rotating speed of the fourth wind wheel is 250 rpm.
In the third embodiment, when the users in the space of the air conditioner are multiple users, the distance between the user farthest from the air conditioner and the air conditioner is taken as the air blowing distance of the first pair of cyclones, and the distance between the user closest to the air conditioner and the air conditioner is taken as the air blowing distance of the second pair of cyclones.
