In a multi-user wind sweeping scene, the intelligent electric fan can determine a wind sweeping range based on the position of a human body, but if the position or the number of the human body changes in the midway, namely the distribution state of the human body changes, the electric fan still performs head shaking control based on the current wind sweeping range, and at the moment, a function key such as intelligent person searching needs to be manually operated to enable the electric fan to determine the wind sweeping range again, so that the problems that the operation is not intelligent and the user experience is influenced exist.
Based on the technical scheme, the target main body in the electric fan sweeping range is automatically detected, so that the sweeping boundary of the electric fan is automatically determined again according to the distribution state of the target main body, and then the sweeping area is determined according to the sweeping boundary, and the sweeping area of the electric fan can be ensured to cover all the target main bodies.
According to an embodiment of the invention, there is provided an embodiment of a method of controlling a wind sweeping device, it being noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions and that, although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
In this embodiment, a control method of a wind sweeping device is provided, which can be used for an electrical appliance with a wind sweeping function, such as a floor fan, a desk fan, an electric fan, and the like, fig. 1 is a flowchart of the control method of the wind sweeping device according to an embodiment of the present invention, and as shown in fig. 1, the flowchart includes the following steps:
and S11, acquiring the distribution state of the target subject, and determining the wind sweeping boundary of the wind sweeping device based on the distribution state of the target subject.
The number of target subjects may be one, two, or more. The distribution state of the target subject is the distribution condition of the target subject in the corresponding wind sweeping range of the wind sweeping device, and specifically, the distribution state of the target subject may include the gathering state of the target subject and the number of people change state of the target subject. The aggregation state of the target body is the aggregation degree of the target body, and can be characterized by the position of each target body. If the positions of the target bodies are dense, representing that the target bodies are in an aggregation state; and if the positions of the target bodies are more dispersed, representing that the target bodies are in a dispersed state. The number of people change state of the target subject is the number of people of the target subject within the wind sweeping range, and comprises the increase of the number of the target subject and the decrease of the number of the target subject.
The distribution state of the target subject can be acquired through the detection of the camera arranged on the wind sweeping equipment, the visual field of the camera can be changed along with the rotation of the wind sweeping equipment, and therefore the position and the number of people of the target subject can be detected in real time to determine the distribution state of the target subject.
The wind sweeping boundary of the wind sweeping device is the current wind sweeping range corresponding to the wind sweeping device, namely two wind sweeping boundaries corresponding to the wind sweeping device can be determined according to the position of the target main body, and the two wind sweeping boundaries form the wind sweeping range of the wind sweeping device. As shown in fig. 4, the x-line is a left wind sweeping boundary, the y-line is a right wind sweeping boundary, and a range of an included angle formed by the x-line and the y-line is a current wind sweeping range of the wind sweeping device. It should be noted that, if there is only one target body currently, the wind sweeping device may directionally blow wind and change the blowing direction by tracking the movement of the target body.
And S12, judging whether the distribution state of the target main body in the wind sweeping boundary changes or not.
The change of the distribution state of the target main body comprises the change of the number of people of the target main body in the windsweeping boundary and the change of the position of the target main body. The wind sweeping device can determine whether the distribution state of the target main body in the wind sweeping boundary changes or not based on the target main body detected in real time by the wind sweeping device. And when the distribution state of the target main body in the wind sweeping boundary changes, executing the step S13, otherwise, keeping the wind sweeping boundary of the wind sweeping equipment unchanged, continuing to sweep the wind left and right by using the current wind sweeping boundary, and not searching and detecting the target main body.
And S13, when the distribution state of the target main body changes, controlling the wind sweeping equipment to detect the target main body and determining the current distribution state of the target main body.
When the wind sweeping device detects that the distribution state of the target main body changes, the wind sweeping boundary of the wind sweeping device is possibly required to be determined again, and at the moment, the wind sweeping device can detect the target main body in the current wind sweeping range or the wind sweeping limit area of the wind sweeping device so as to determine the distribution state of the target main body again.
Specifically, the wind sweeping device may determine whether the number of target subjects in the current wind sweeping boundary changes, and the wind sweeping device may detect the target subjects located in the current wind sweeping boundary through the camera to determine whether the number of the target subjects in the wind sweeping device decreases, and may determine that the target subjects away from the wind sweeping boundary exist if the number of the target subjects decreases, and at this time, the wind sweeping device may perform detection of the target subjects in a wind sweeping limit area thereof to determine a current distribution state of the target subjects.
Specifically, when the number of target subjects in the wind sweeping boundary is not changed, the wind sweeping device may further detect whether the position of the target subject is changed, and the wind sweeping device may detect the target subjects located in the current wind sweeping boundary through the camera to determine the current positions of the target subjects, so as to determine the aggregation degree of the target subjects. If the target bodies are located at positions which are changed from being densely distributed or being densely distributed, the wind sweeping device can determine the distribution state of the target bodies based on the densely distributed or the dispersedly distributed target bodies.
Taking fig. 4 as an example, an included angle between the line a and the line b is a camera view, and the camera view can be changed along with the rotation of the wind sweeping device, so as to detect the distribution state of the target subject in the wind sweeping boundary in real time.
And S14, determining the target wind sweeping boundary of the wind sweeping device based on the current distribution state of the target main body.
The target wind sweeping boundary is an actual wind sweeping range determined by the wind sweeping equipment according to the current distribution state of the target main body. Specifically, the wind sweeping equipment can determine the minimum wind sweeping angle covering all the target main bodies according to the current distribution state of the target main bodies, the minimum wind sweeping angles respectively correspond to the left wind sweeping boundary and the right wind sweeping boundary, and the wind sweeping equipment updates the wind sweeping boundaries of the wind sweeping equipment according to the current left wind sweeping boundary and the current right wind sweeping boundary so as to determine the target wind sweeping boundaries of the wind sweeping equipment, so that the wind sweeping equipment can sweep wind according to the updated target wind sweeping boundaries.
According to the control method of the wind sweeping equipment, the distribution state of the target main body is detected in real time, so that the target wind sweeping boundary of the wind sweeping equipment can be automatically determined again when the distribution state of the target main body changes in the wind sweeping boundary, the target wind sweeping boundary of the wind sweeping equipment can be maximally covered with all the target main bodies, manual operation is not needed in the process, complex manual operation is avoided, the control of the wind sweeping equipment is more intelligent, and user experience is improved.
In this embodiment, a control method of a wind sweeping device is provided, which can be used for an electrical appliance with a wind sweeping function, such as a floor fan, a desk fan, an electric fan, etc., and fig. 2 is a flowchart of the control method of the wind sweeping device according to the embodiment of the present invention, as shown in fig. 2, the flowchart includes the following steps:
and S21, acquiring the distribution state of the target subject, and determining the wind sweeping boundary of the wind sweeping device based on the distribution state of the target subject. For a detailed description, reference is made to the related description of step S11 corresponding to the above embodiment, and details are not repeated herein.
And S22, judging whether the distribution state of the target main body in the wind sweeping boundary changes or not. For a detailed description, reference is made to the related description of step S12 corresponding to the above embodiment, and details are not repeated herein.
And S23, when the distribution state of the target main body changes, controlling the wind sweeping equipment to detect the target main body and determining the current distribution state of the target main body.
Specifically, the step S23 may include the following steps:
and S231, improving the wind sweeping speed of the wind sweeping equipment.
The wind sweeping speed of the wind sweeping device is determined by the speed of the stepping motor arranged in the wind sweeping device. When the target main body is detected to leave the wind sweeping boundary of the wind sweeping device, the wind sweeping device can control the speed of the stepping motor to be increased, so that the wind sweeping speed of the wind sweeping device is increased, the rapid rotation of the wind sweeping device drives the camera to rotate, and the detection efficiency of the target main body is improved. Specifically, if the current speed of the stepping motor is V1, when the wind sweeping device detects that the target subject leaves the wind sweeping boundary, the speed of the stepping motor may be controlled to be increased to V2 in the detection process of the target subject, wherein the increased speed of the stepping motor may be set according to the time for acquiring the image of the target subject by the camera, so as to ensure that the wind sweeping device can rapidly complete the detection of the target subject.
And S232, controlling the wind sweeping equipment to detect the target subject based on the improved wind sweeping speed, and determining the current distribution state of the target subject.
If the wind sweeping equipment detects that the number of the target main bodies in the current wind sweeping boundary is not changed, the wind sweeping equipment sweeps wind at the improved wind sweeping speed and detects the distribution positions of the target main bodies in the current wind sweeping boundary so as to determine whether the gathering state of the target main bodies is changed. Specifically, if the position of the target subject located at the windsweeping boundary changes, the distribution state of the target subject needs to be obtained again to determine the aggregation state of the target subject, and the windsweeping angle of the windsweeping device is updated according to the aggregation state. For example, if the target subject located at the wind sweeping boundary moves within the wind sweeping boundary, the current wind sweeping boundary may reduce the wind sweeping angle based on the aggregation state of the target subject.
If the wind sweeping equipment detects that the number of the target main bodies in the current wind sweeping boundary changes, the wind sweeping equipment sweeps wind at the improved wind sweeping speed and swings heads in the wind sweeping limit area at the same time so as to detect the distribution positions of the target main bodies in the wind sweeping limit area and to re-determine the distribution positions of the target main bodies, namely the current distribution state of the target main bodies. The wind sweeping limit area is the maximum wind sweeping range of the wind sweeping equipment. The sweeping limit area of the sweeping device can be determined by the oscillation parameters of the sweeping device, wherein the oscillation parameters of the sweeping device are arranged in a processor of the sweeping device. Different panning parameters and different wind sweeping limit areas are shown in fig. 4, namely a left limit position and a right limit position, and the left limit position and the right limit position form the wind sweeping limit area of the wind sweeping device. Taking fig. 5 as an example, the number of target subjects currently located in the windward movement limit area is 3, the position a is a position before the target subject is changed, the position a' is a position after the target subject is changed, and based on the position change of the target subject, the distribution state corresponding to the target subject can be newly specified.
According to the change of the distribution state of the target main body, the wind sweeping equipment can re-determine two wind sweeping boundaries covering all the target main bodies, namely the target wind sweeping boundaries, so that the wind sweeping equipment can sweep wind based on the target wind sweeping boundaries.
Optionally, the step S232 may include the following steps:
(1) and controlling the wind sweeping equipment to rotate in a reciprocating manner in the wind sweeping boundary, and judging whether a target main body is identified in the wind sweeping boundary.
The wind sweeping equipment can detect the distribution state of the target main body in the wind sweeping boundary in real time, and when the distribution position of the target main body in the wind sweeping boundary is detected to be changed, the wind sweeping equipment is controlled to swing left and right in the current wind sweeping boundary, namely the wind sweeping equipment reciprocates to determine whether the target main body is identified in the wind sweeping boundary. And (3) when the target subject is identified, executing the step (2), otherwise, executing the step (3).
As an optional embodiment of the present application, step (1) may include:
11) and judging whether the target main body is identified or not in the process that the wind sweeping equipment rotates to a wind sweeping boundary in the current rotating direction.
The sweeping device may be rotated back and forth within the sweeping boundary to identify the presence of the target subject. When the target main body is not identified in the process that the wind sweeping device rotates to a wind sweeping boundary in the current rotating direction, step 12) is executed, otherwise, the target main body is still in the wind sweeping boundary of the wind sweeping device, and at this time, the target wind sweeping boundary of the wind sweeping device can be further determined based on the current distribution state of the target main body in the wind sweeping boundary.
12) And changing the rotation direction of the wind sweeping equipment, and controlling the wind sweeping equipment to rotate to the other wind sweeping boundary in the changed rotation direction.
When the wind sweeping equipment rotates to the wind sweeping boundary corresponding to the current rotating direction, the target main body is still not identified, the rotating direction of the wind sweeping equipment can be changed, namely the wind sweeping equipment rotates in the direction opposite to the current rotating direction until the wind sweeping equipment rotates to the other wind sweeping boundary.
13) And judging whether the target main body is identified in the process that the wind sweeping equipment rotates to the other wind sweeping boundary or not.
The wind sweeping device continues to perform detection of the target subject during the turning to another wind sweeping boundary in order to determine whether the target subject is present. When the target main body is not identified in the process that the wind sweeping equipment rotates to the other wind sweeping boundary, the target main body is shown to leave the wind sweeping boundary of the wind sweeping equipment, otherwise, the target main body is still in the wind sweeping boundary of the electric fan, and at the moment, the target wind sweeping boundary of the wind sweeping equipment can be further determined based on the current distribution state of the target main body in the wind sweeping boundary.
It should be noted that: when the wind sweeping equipment rotates to the wind sweeping boundary, rotation angle compensation can be carried out, and whether the target main body is identified after rotation angle compensation is judged. The rotation angle compensation is that the wind sweeping equipment rotates one more compensation angle when rotating to the wind sweeping boundary. When the wind sweeping equipment performs target main body detection, the wind sweeping equipment can rotate one more compensation angle when shaking the head to the wind sweeping boundary so as to make up for the defect of small imaging angle of the camera, realize the maximum detection of the target main body and avoid the detection omission of the target main body. The angle between line c and line x and the angle between line d and line y as shown in fig. 4 are both rotational compensation angles. The compensation angle can be 10 °, and other angles can be determined by those skilled in the art according to actual needs.
(2) Based on the identified current location of the target subject, a current distribution state of the target subject is determined.
When the wind sweeping equipment identifies the target main body with the changed distribution state in the wind sweeping boundary, the position of the current target main body in the wind sweeping boundary can be obtained, and the current distribution state of the target main body in the wind sweeping boundary is determined based on the positions of all the target main bodies in the current wind sweeping boundary.
(3) And when the target main body is not identified in the wind sweeping boundary, judging that the target main body leaves the wind sweeping boundary, and controlling the wind sweeping equipment to preferentially turn to the wind sweeping limit boundary closest to the current wind sweeping position to detect the target main body.
The wind sweeping limit boundary is a wind sweeping boundary corresponding to a wind sweeping limit area of the wind sweeping equipment. When the target subject with the changed distribution state is not identified in the wind sweeping boundary of the wind sweeping equipment, the target subject can be judged to leave the wind sweeping boundary, and at the moment, the wind sweeping equipment can be controlled to detect the target subject in the wind sweeping limit area. When the wind sweeping equipment starts to detect the target main body in the wind sweeping limit area, the wind sweeping equipment can preferentially turn to the wind sweeping limit boundary closest to the current wind sweeping position so as to improve the detection efficiency of the target main body.

Specifically, the step S24 may include:
and S241, determining the wind sweeping angle of the wind sweeping device based on the current distribution state of the target main body.

The sweeping angle of the sweeping device is an included angle formed by the position of the first target main body and the position of the last target main body, namely the included angle formed by the position of the first target main body, an electric fan sweeping arc line and the position of the last target main body.
Specifically, the step S241 may include:
(1) and determining the position of the target subject based on the current distribution state of the target subject.
The current position of each target subject can be determined based on the current distribution state of the target subject. Taking fig. 5 as an example, the current positions of the 3 target subjects can be determined based on the current distribution state of the target subjects, for example, the position a is the position before the target subject is changed, and the position a' is the position after the target subject is changed.
(2) And judging whether the position of the target main body exceeds the wind sweeping boundary of the wind sweeping device.
The wind sweeping equipment swings back and forth in the wind sweeping boundary, and meanwhile the target main body is detected in real time through the camera arranged on the wind sweeping equipment, so that whether the current position of the target main body is located in the wind sweeping boundary or not can be determined, namely whether the position of the target main body exceeds the wind sweeping boundary or not can be determined. When the target body is located at a position not exceeding the wind sweeping boundary of the wind sweeping device, executing the step (4); and (4) when the position of the target main body exceeds the wind sweeping boundary of the wind sweeping device, further judging whether the position of the target main body exceeds the wind sweeping limit area of the wind sweeping device, when the position of the target main body does not exceed the wind sweeping limit area of the wind sweeping device, executing the step (3), otherwise, re-determining the distribution state of the target main body by the wind sweeping device according to the target main body currently positioned in the wind sweeping limit area, and determining the target wind sweeping boundary according to the re-determined distribution state of the target main body.
(3) And expanding the wind sweeping angle of the wind sweeping device based on the position of the target main body.
When the position of the target main body exceeds the wind sweeping boundary but does not exceed the wind sweeping limit boundary of the wind sweeping device, the wind sweeping range of the wind sweeping device can cover all the target main bodies, at the moment, the wind sweeping device can acquire the position of the target main body exceeding the wind sweeping boundary, and expand the wind sweeping angle of the wind sweeping device based on the current position of the target main body, namely, the wind sweeping angle of the wind sweeping device is expanded to the position of the target main body exceeding the wind sweeping boundary. As shown in fig. 5, the position a is a position before the target subject is changed, and the sweep range between the left sweep boundary x line and the right sweep boundary y line is a sweep area before the target subject is changed; and when the target main body is changed to the position A ', the right wind sweeping boundary Y line is changed to the position A', and the changed right wind sweeping boundary Y line is obtained. The wind sweeping angle of the electric fan can be obtained based on the left wind sweeping boundary x line and the changed right wind sweeping boundary Y line, as shown in fig. 6.
(4) Determining a wind sweeping angle of the wind sweeping device based on the position of the target subject.
When the position of the target main body does not exceed the wind sweeping boundary, the target main body is still located in the wind sweeping boundary of the wind sweeping device, and at the moment, the wind sweeping device can re-determine the wind sweeping angle of the target main body based on the current position of the target main body, namely the included angle formed by the position of the first target main body and the position of the last target main body.
When there are 3 or more target subjects, if the position of the first target subject and the position of the last target subject do not change, and only if other target subjects change between the position of the first target subject and the position of the last target subject, the wind sweeping angle is not changed, and the wind sweeping device continues to sweep at the current wind sweeping angle.
And S242, determining a target wind sweeping boundary of the wind sweeping device based on the wind sweeping angle.
The wind sweeping equipment can determine a target wind sweeping boundary corresponding to the wind sweeping equipment according to the determined wind sweeping angle, and then the wind sweeping equipment can sweep wind according to the updated target wind sweeping boundary.
Specifically, the step S242 may include:
(1) and acquiring a rotation compensation angle of the wind sweeping equipment.
The rotation compensation angle is the angle of multiple rotations of the wind sweeping equipment when the wind sweeping equipment rotates to the wind sweeping boundary. The wind sweeping equipment can rotate one more compensation angle when shaking the head to the wind sweeping boundary, and on the basis of making up the defect that the imaging angle of the camera is small and the detection omission of the target main body is avoided, the wind sweeping range can be maximally covered on all the target main bodies.
(2) And determining a target wind sweeping boundary of the wind sweeping equipment based on the rotation compensation angle and the wind sweeping angle.
And adding the rotation compensation angle on the basis of the wind sweeping angle as a final wind sweeping angle of the wind sweeping device, and calculating a target wind sweeping boundary of the wind sweeping device on the basis of the final wind sweeping angle, so that the maximization of the wind sweeping range of the wind sweeping device is realized.

Meanwhile, the current state of the wind sweeping equipment can be intuitively determined based on the wind sweeping speed of the wind sweeping equipment, so that a user can distinguish the wind sweeping state of the wind sweeping equipment from the target subject detection state. When the target main body is determined to leave the wind sweeping boundary of the wind sweeping device, the wind sweeping device is controlled to preferentially turn to the wind sweeping limit boundary closest to the current wind sweeping position so as to detect the target main body, the detection efficiency of the target main body is improved, and the current distribution state of the target main body is rapidly determined.
