In an example, the scene characteristic information includes position distribution information of personnel in an indoor area, and an air supply angle parameter of the fan blade is determined according to the position distribution information of the personnel in the indoor area.

For example, N persons exist in the indoor area, and the angular range [ theta ] of the swing amplitude of the fan blade is determined according to the angular ranges of the N azimuth angles_min，θ_max](ii) a Here, θ_min＝Min{θ₁、θ₂、θ₃、……θ_i……θ_N}，θ_max＝Max{θ₁、θ₂、θ₃、……θ_i……θ_N}。

For example, a person exists in the indoor area, and the azimuth angle of the person relative to the position of the air conditioner is determined as the azimuth angle theta of the central axis of the swing amplitude of the fan blade₀At this time, the blowing angle of the air conditioner can be controlled to be maintained at θ₀。

Or the azimuth angle of the central axis according to the swing amplitude of the fan blade is theta₀Determining the swing amplitude of the fan blade to be within an angle range theta₀±θ_aControlling the air conditioner to be theta₀As central axis of oscillation amplitude, at + -theta_aIs swung within the angular range of (a).

Here, θ_aCan be in the angle range of [0 DEG, 90 DEG ]]The user preset theta may be received by the air conditioner_aValue of (a) to_aIs stored in advance, and theta is called during the operation of the air conditioner_aTo obtain theta₀±θ_a。

In an example, an air conditioner receives location information of a movable device relative to the air conditioner when the movable device identifies a person under preset conditions. Here, the preset condition includes that the distance between the movable equipment and the person is less than a preset value. And determining the position information of the movable equipment relative to the air conditioner as the position information of the person relative to the air conditioner to obtain the position information of at least one person in the indoor area.

In an example, referring to fig. 6, the air conditioner 101 sends a control command to the movable device 102, the movable device 102 receives the control command of the air conditioner 101, the movable device 102 takes the charging position in the air conditioner 101 as an initial position, and when the hatch door of the air conditioner 101 is in an open state, the movable device 102 can cruise the indoor area starting from the charging position in the air conditioner 101.

In an example, air conditioner 101 sends a control instruction to mobile device 102, and when controlling mobile device to cruise in an indoor area, records moving distances of mobile device 102 in an X direction and a Y direction on the floor of the indoor area. Here, the X direction corresponds to the positive direction of the X axis in the environment map information of the indoor area, and the Y direction corresponds to the positive direction of the Y axis in the environment map information of the indoor area.

In an example, mobile device 102 determines the coordinate position of mobile device 102 in the indoor area at time t based on the distance moved by mobile device 102 in the X-direction and the Y-direction of the floor of the indoor area at time t.

In an example, referring to fig. 6, the movable device 102 records coordinate information of the floor surface of the indoor area from the charging position in the air conditioner 101, with the Y axis in the environment map information as the moving direction and with the distance point of 30 centimeters as the moving distance.

In an example, the movable device 102 moves forward 30 cm toward the X axis in the environment map information when an obstacle is detected, and continues to move toward the zero point of the Y axis in the environment map information.

In an example, the movable device 102 is provided with a distance sensor, the movable device 102 cruises an indoor area where the air conditioner 101 is located according to a cruise route, and when a distance between the movable device 102 and an ith person is less than a preset distance at time t, position information of the movable device 102 in the indoor area at time t is recorded.

In an example, the indoor area includes N persons, and when the mobile device 102 navigates the indoor area according to the cruising route, the position information of the indoor area corresponding to the 1 st to nth persons is recorded.

In an example, the mobile device 102 is provided with any one of the following air conditioning modules: the air conditioner comprises an air purification module, an air humidification module, an air supply refrigeration module and an air supply heating module. The air conditioner 101 sends a control instruction to the mobile device 102 to control the mobile device 102 to perform conditioning control on the environment of the indoor area based on any one of the air conditioning modules when the indoor area is cruising.

Step A502: receiving position information of the movable equipment relative to the air conditioner when the movable equipment identifies people under a preset condition; the preset condition includes that the distance between the movable equipment and the personnel is smaller than a preset value.

In an example, a communication connection is maintained between air conditioner 101 and mobile device 102 using wireless communication techniques. The movable equipment 102 transmits, to the air conditioner 101, position information of the movable equipment with respect to the air conditioner when the movable equipment recognizes a person under a preset condition in the course of cruising the indoor area.

In an example, air conditioner 101 receives location information of a mobile device relative to the air conditioner when mobile device 102 identifies a person under preset conditions. Here, the preset condition includes that the distance between the movable apparatus 102 and the person is less than a preset value. Therefore, the position information of the person can be approximated, and the position information of at least one person in the indoor area can be acquired.

In an example, when the distance between mobile device 102 and the person does not satisfy the preset condition, mobile device 102 continues to cruise the indoor area along the cruising route.

Step A503: the position distribution information of the person in the indoor area is acquired based on the position information of the movable equipment relative to the air conditioner.

In the example, the position information of the movable device 102 relative to the air conditioner 101 at time t is determined as the position information of the i-th person in the indoor area, based on the position information of the movable device 102 relative to the air conditioner 101 at time t.

Therefore, when the scene characteristic information of the indoor area is acquired according to the position information of the movable equipment relative to the air conditioner, the position distribution conditions of different people in the indoor area can be accurately presented in the scene characteristic information.

In one implementation, in step a503, acquiring the information of the location distribution of the person in the indoor area according to the information of the location of the mobile device relative to the air conditioner may include the following steps:

determining the position information of the personnel relative to the air conditioner according to the position information of the movable equipment relative to the air conditioner; and acquiring scene characteristic information of the indoor area according to the position information of the personnel relative to the air conditioner.

In the example, the positional information of the movable device 102 with respect to the air conditioner 101 is determined as the positional information of the person 103 with respect to the air conditioner 101, based on the positional information of the movable device 102 with respect to the air conditioner 101. Referring to fig. 7, during a time period t1, the main body 101 receives information of the position of the mobile device relative to the air conditioner when the mobile device 102 recognizes a person under preset conditions, and may include the following coordinate points: (x1, y1), (x2, y2), (x3, y3), (x4, y4), (x5, y 5). Wherein each coordinate point corresponds to a location of a person in the indoor area.

In an example, the air conditioner 101 determines the location information of the movable device 102 with respect to the air conditioner 101 as the location information of the person 103 with respect to the air conditioner 101, thereby obtaining the location information of at least one person in the indoor area. Further, the air conditioner 101 acquires the position distribution information of the persons in the indoor area according to the position information of at least one person in the indoor area, thereby obtaining the scene characteristic information of the indoor area.

In one implementation, sending the control instruction to the removable device may include the steps of: and sending a control instruction to the movable equipment every preset time length.

In the example, air conditioner 101 sends control instructions to mobile device 102 every preset time period, and when the mobile device is controlled to cruise in the indoor area again, the position information of mobile device 102 relative to air conditioner 101 when mobile device 102 identifies a person under preset conditions is recorded.

Accordingly, the main body 101 may re-receive the position information of the movable device 102 with respect to the air conditioner 101 when the movable device 102 recognizes the person under the preset condition, and re-determine the position distribution information of the person in the indoor area, thereby dynamically updating the scene characteristic information of the indoor area.

In the embodiment of the application, the control instruction is sent to the movable device at intervals of a preset time period. Therefore, scene characteristic information of the indoor area can be acquired at intervals of preset duration; and dynamically adjusting the running state of the air conditioner according to the change of the scene characteristic information, so that the running state of the air conditioner is matched with the scene characteristic information of the indoor area, and the control precision of the running state of the air conditioner is improved.

For example, the azimuth angle of each person in the indoor area with respect to the position of the air conditioner 101 is calculated using the Arctan function Arctan (xn/yn).

In an example, referring to fig. 10, during time period t2, mobile device 102 receives information about the location of the mobile device relative to the air conditioner when mobile device 102 identifies a person under preset conditions, which may include the following coordinate points: (x1, y1), (x2, y2), (x3, y3), (x4, y4), (x5, y 5).

It should be understood that, from the distribution information of persons at the t1 time period shown in fig. 7 and the distribution information of persons at the t2 time period shown in fig. 10, it can be seen that the coordinate positions of persons in the indoor area are in dynamic change from the t1 time period to the t2 time period.

In the example, | θ_min-θ_maxAnd when the | is smaller than a preset value, determining that the distribution of the people in the indoor area is concentrated. In this case, the angular range of the swing amplitude of the fan blade of the air conditioner 101 can be reduced, and ineffective air supply to the angular range of the indoor area can be reduced.

In the example, | θ_min-θ_maxAnd if the | is larger than the preset value, determining that the personnel distribution in the indoor area is relatively dispersed. In this case, the range of the swing amplitude of the fan blades of the air conditioner 101 can be increased, and the cooling requirement of each person in the indoor area can be met.

In an example, the minimum value θ according to the azimuth angle of each person in the indoor area_minMaximum value θ_maxDetermining the swing amplitude of the fan bladeThe azimuth of the central axis of (c) is as follows:

θ＝1/2(θ_min+θ_max) (3)

in an example, according to the personnel distribution information at the time t1 in fig. 7 and the personnel distribution information at the time t2 in fig. 10, the azimuth angle theta of the central axis of the swinging amplitude of the fan blade at the time t1 and the time t2 are respectively determined₁、θ₂As follows:

θ₁＝1/2(θ_min+θ_max)＝{Arctan(x1/y1)+Arctan(x5/y5)}/2 (4)

θ₂＝1/2(θ_min+θ_max)＝{Arctan(x2/y2)+Arctan(x4/y4)}/2 (5)
