Furthermore, heartbeat signals of the target blowing angle interval can be detected through the millimeter wave human sensing module, the number of human bodies can be determined according to the number of the heartbeat signals, or breathing signals of the target blowing angle interval can be detected through the millimeter wave human sensing module, and the number of the human bodies can be determined according to the number of the breathing signals.

Further, after the step S11, the method further includes:

and step S12, if the number of human bodies in the target blowing angle interval is 0, controlling the target air deflector to blow air at a preset swing angle.

In this embodiment, the preset swing angle is preset by the operation and maintenance personnel, and at this angle, the air deflector can realize the maximum air output through the same fan rotating speed. If the number of the human bodies in the target blowing angle interval is 0, the situation that no human body exists in the target blowing angle interval is judged, and human body tracking air supply is not needed, so that air supply at a preset air swing angle can be realized by controlling the target air deflector, and the air supply efficiency of the ceiling fan is improved.

Further, after the step S11, the method further includes:

step S13, if the number of human bodies in the target blowing angle interval is greater than or equal to 2, detecting the angle of each human body deviating from the angular bisector of the target blowing angle interval corresponding to the target air deflector, the distance between each human body and the ceiling fan, and the included angle of the connecting line of each human body and the ceiling fan relative to the plumb line through the millimeter wave human perception module, wherein the target air deflector is the air deflector in the blowing mode;

step S14, determining a plurality of wind swinging angles according to the angle of the bisector of the target wind blowing angle interval corresponding to the deviation of each human body from the target wind deflector, the distance between each human body and the ceiling fan, and the included angle of the connecting line of each human body and the ceiling fan relative to the plumb line;

step S15, determining the maximum value and the minimum value in the plurality of swing wind angles;

and step S16, controlling the target air deflector to swing and blow air between the maximum value and the minimum value.

In this embodiment, if the number of human bodies in the target blowing angle interval is greater than or equal to 2, the millimeter wave human detection module detects the angle of the bisector of each human body in the target blowing angle interval, which is deviated from the target blowing angle interval corresponding to the target air deflector, the distance between each human body and the ceiling fan, and the included angle of the connecting line between each human body and the ceiling fan with respect to the vertical line, similar to the calculation method in step S20, further calculates the pendulum wind angle corresponding to each human body according to the position information of each human body, compares the magnitudes of the pendulum wind angles, determines the maximum value and the minimum value of the pendulum wind angles, controls the target air deflector to swing between the maximum value and the minimum value to supply air, so that each human body in the target blowing angle interval can blow air while shortening the round-trip path of the target air deflector, further shortens the round-trip duration, and prevents the air from blowing to an unmanned area, the wind is blown to the human body as much as possible and as fast as possible, and the comfort level of the user is improved.

Further, based on the foregoing embodiment, a third embodiment of the ceiling control method according to the present invention is provided, where in this embodiment, before step S10, the method further includes:

step S101, detecting the air outlet mode of each air deflector;

for the air deflector with the air outlet mode being the blowing mode, executing the following steps:

in this embodiment, the air deflectors are independent from each other, and each air deflector can support different air outlet modes at the same time. The air outlet mode includes, but is not limited to, any one of a standard mode, a swing mode, a wind avoiding mode, a wind blowing mode and a custom mode.

The mode of blowing the people by wind refers to that the wind deflector swings along with the movement of the people so as to blow the wind to the human body; and the self-defining mode refers to that the air guide plate supplies air according to the air guide plate angle set by a user.

Further, after step S101, the method further includes:

the air deflector for controlling the air outlet mode to be the wind avoiding mode supplies air at a first limit angle, and the first limit angle deviates from the direction of the human body;

controlling the air deflector with the air outlet mode being the swing mode to swing and supply air between the first limit angle and the second limit angle;

and the air guide plate for controlling the air outlet mode to be the standard mode supplies air at a preset air swinging angle.

In this embodiment, the standard mode refers to that the air deflector is fixed to supply air at a preset swing angle, and at the angle, the air deflector can achieve the maximum air output through the same fan rotating speed; the swinging mode refers to that the air deflector swings for air supply between a first limit angle and a second limit angle, wherein the limit angles are limited by a mechanical structure, so that the air deflector can only swing between the first limit angle and the second limit angle; the wind avoiding mode refers to that the wind deflector supplies wind at a first limit angle, and the first limit angle deviates from the direction of a human body, so that the wind supply direction deviates from the human body.

In the embodiment, different air deflectors can support different air supply modes at the same time, and the air supply requirements of users in various aspects are met.
