In one embodiment, as shown in fig. 3, the step of determining a first relative angle of each user with respect to the first electric fan includes:
s310, acquiring a first distance detected by a first distance sensor and a second distance detected by a second distance sensor; wherein, the first distance sensor and the second distance sensor are both arranged on the first electric fan; the connecting line between the first distance sensor and the second distance sensor is parallel to the ground; the first distance is the distance between the user and the first distance sensor; the second distance is the distance between the user and the second distance sensor;
the first distance sensor and the second distance sensor are any sensor capable of detecting distance, and may be an infrared sensor, an ultrasonic sensor, or the like. The distance between the first distance sensor and the second distance sensor is also a value measured in advance. The connecting line between the first distance sensor and the second distance sensor is parallel to the ground, so that the accuracy of the subsequent calculation angle is facilitated. In a specific example, the first distance sensor and the second distance sensor are arranged at a non-swinging part of the first electric fan, and the positions of the first distance sensor and the second distance sensor are not changed along with the swinging of the first electric fan. Further, a line connecting the first distance sensor and the second distance sensor may be perpendicular to the reference line.
S320, according to the first distance and the second distance, the relative position angle of each user relative to the first electric fan is obtained.
Specifically, a triangle is formed among the user, the first distance sensor and the second distance sensor, and under the condition that the lengths of three sides of the triangle are known, a first angle of any one user relative to the first distance sensor (namely, an angle between a first connecting line and a second connecting line, which are the connecting lines of the user and the first distance sensor) and a second angle of any one user relative to the second distance sensor (namely, an angle between a third connecting line and the second connecting line, which is the connecting line of the user and the second distance sensor) can be determined according to a trigonometry method.
The midpoint between the first distance sensor and the second distance sensor is taken as the position of the first electric fan. Under the condition that a first angle of any user relative to the first distance sensor and two side lengths corresponding to the first angle are obtained, an angle between a fourth connecting line and a fifth connecting line can be obtained, wherein the fourth connecting line is a connecting line of any user and the middle point; the fifth connecting line is a connecting line between the midpoint and the first distance sensor. The reference line is perpendicular to the second connecting line, so that the angle of any user relative to the first electric fan can be obtained. Alternatively, when the second angle of any one user with respect to the second distance sensor and the lengths of the two sides corresponding to the second angle are obtained, the angle between the fifth connection line and the sixth connection line; the sixth connecting line is a connecting line between the midpoint and the second distance sensor. The reference line is perpendicular to the second connecting line, so that the angle of any user relative to the first electric fan can be obtained.
In one embodiment, as shown in fig. 4, the step of determining the second relative angle of each user with respect to the second electric fan includes:
s410, acquiring a third distance detected by a third distance sensor and a fourth distance detected by a fourth distance sensor; wherein, the third distance sensor and the fourth distance sensor are both arranged on the second electric fan; the connecting line between the third distance sensor and the fourth distance sensor is parallel to the ground; the third distance is the distance between the user and the third distance sensor; the fourth distance is the distance between the user and the fourth distance sensor;
the third distance sensor and the fourth distance sensor are arranged at the non-swinging part of the second electric fan, and the positions of the third distance sensor and the fourth distance sensor are not changed along with the swinging of the second electric fan. Further, the line connecting the third distance sensor and the fourth distance sensor may be perpendicular to the reference line.
S420, according to the third distance and the fourth distance, the relative position angles of the users relative to the second electric fan are obtained respectively.
In particular, the second relative angle may be obtained by reference to the first relative angle step.
In one embodiment, the method further comprises:
acquiring a set wind power gear;
According to the first distance or the second distance, the motor rotating speed of the first electric fan corresponding to the wind power gear is adjusted;
and according to the third distance or the fourth distance, adjusting the motor rotating speed of the second electric fan corresponding to the wind power gear.
Specifically, wind power caused by different motor speeds is also different, and wind speeds generated by the electric fan at different positions can be influenced by various factors, including design, power, blade shape, rotation speed and the like of the electric fan. Meanwhile, the wind speed is gradually reduced along with the distance from the electric fan.
In the process, the motor rotating speed corresponding to the wind power gear can be adaptively increased according to the first distance or the second distance, so that the wind speeds felt by users at different distances are consistent or approximately the same. Since the difference between the first distance and the second distance is not large in the actual state, either one of the first distance or the second distance may be selected as a criterion for adjusting the rotational speed of the motor. The motor rotating speed corresponding to the wind power gear is adjusted to obtain the motor rotating speed corresponding to any user. Similarly, the motor rotation speed of the second electric fan corresponding to the wind power gear can be adjusted according to the third distance or the fourth distance.

acquiring the wind speed of an air outlet of each wind power gear, and presetting a corresponding relation table of the wind speed and the distance;
according to the first distance and the corresponding relation table, the rotating speed of the motor is adjusted to enable the wind speed at the first distance to reach the wind speed of the air outlet, or,
and according to the second distance and the corresponding relation table, adjusting the rotating speed of the motor to enable the wind speed at the second distance to reach the wind speed of the air outlet.
Specifically, the air outlet air speed refers to the air speed of the electric fan at the air outlet position, and the air outlet refers to the position of the blade net frame. The wind speed of the wind outlet of each wind power gear can be obtained by testing a corresponding relation table of preset wind speed and interval by adopting wind speed measuring equipment in advance. It should be noted that, not only the wind speed of the wind outlet of each wind power gear may be used as a reference, but also any value may be preset as a reference.
According to the motor rotating speed adjusting method, the users can be located at different distances, and the sensed wind power of the first electric fan is almost the same.

according to the third distance and the corresponding relation table, the rotating speed of the motor is adjusted to enable the wind speed at the third distance to reach the wind speed of the air outlet, or,
and according to the fourth distance and the corresponding relation table, adjusting the rotating speed of the motor to enable the wind speed at the fourth distance to reach the wind speed of the air outlet.
Specifically, according to the motor rotation speed adjusting method, the users can be located at different distances, and the sensed wind power of the second electric fan is almost the same.
