Based on the double-air-channel air conditioner (hereinafter referred to as an air conditioner), the invention also provides a double-air-channel air conditioner control method for adjusting the air outlet of the double-air-channel air conditioner.
Referring to fig. 2, a first embodiment of a dual-duct air conditioner control method according to the present invention is provided, where the dual-duct air conditioner control method includes:
step S10, acquiring the position information of a target user in the space where the double-air-channel air conditioner is located;
in a preset mode (e.g., a wind sensing mode), the outlet air of the air conditioner avoids the user. Therefore, when the air conditioner is in the preset mode, the position information of the target user in the space where the air conditioner is located can be obtained in real time.
The position information is specifically characteristic information representing the position of the target user in the space, and can be used for determining the relative position information of the target user relative to the air conditioner. The location information may specifically include a direction and/or distance of the target user relative to the air conditioner, etc. The position information may be obtained based on data collected by a human detection device (e.g., a camera, an infrared sensor) disposed in a space where the air conditioner is located (e.g., on a body of the dual duct air conditioner).
The target user may be a specific user, or may be all users in the space. The number of target users may be one or more than one. The number of the acquired position information can be correspondingly one or more than one according to the different number of the target users.
Step S20, determining a first air outlet direction avoiding the target user in the first air outlet area and a second air outlet direction avoiding the target user in the second air outlet area according to the position information;
under the action of the first air guide piece, the maximum range which can be covered by the air outlet of the first air outlet is defined as a first air outlet area; under the action of the second air guide piece, the maximum range which can be covered by the air outlet of the second air outlet is defined as a second air outlet area. Wherein, in order to improve the coverage degree of air conditioner air-out, realize that its air-out has great adjustable and controllable region, first air-out region and second air-out region overlap the setting.
The first air outlet parameter refers to a flow characteristic parameter of air blown out from the first air outlet in a first air outlet area, and specifically includes an air outlet direction, a wind sweeping direction and/or a wind sweeping area. The second air outlet parameter refers to a characteristic parameter of the flow of the air blown out from the second air outlet in the second air outlet area, and specifically includes an air outlet direction, a wind sweeping direction and/or a wind sweeping area. The first air outlet direction is the direction in which the air outlet of the first air outlet in the first air outlet area cannot blow the user directly; the second air outlet direction is the direction in which the air outlet of the second air outlet in the second air outlet area can not blow the user directly.
Wherein the different location information represents relative locations between different users and the air conditioner. Because the first air outlet area and the second air outlet area are fixed areas, the positions of the target user relative to the first air outlet area and the second air outlet area can be determined according to the position information. Based on the position of the target user relative to the first air-out area, when the target user is located in the first air-out area, the direction of the target user can be directly blown out of the first air-out area, and the first air-out direction is selected from other directions except the direction of the target user in the first air-out area, so that the condition that the air outlet of the first air outlet cannot be blown out to the target user can be ensured. Based on the position of the target user relative to the second air-out area, when the target user is located in the second air-out area, the direction of the target user can be directly blown out of the second air-out area, and the second air-out direction is selected from other directions except the direction of the target user in the second air-out area, so that the condition that the air outlet of the second air outlet cannot be blown out to the target user can be ensured.
The determined first air outlet direction and the second air outlet direction may specifically be a preset specific direction corresponding to the current position information. For example, a plurality of preset directions are preset in the first air outlet region, the first direction in which the target user is located can be determined based on the position information, and the first air outlet direction is selected from other directions except the first direction in the preset directions, for example, the first preset direction farthest from the first direction is taken as the first air outlet direction. The second air outlet direction can also be determined by analogy, which is not described herein.
In addition, in order to flexibly adapt to different position distributions of target users to determine accurate air outlet directions when a plurality of target users exist, the first air outlet direction and the second air outlet direction can be determined based on the current position distribution of the target users.
And step S30, controlling the first air guide to operate according to the first air outlet direction, and controlling the second air guide to operate according to the second air outlet direction.
Different air outlet directions correspond to different running states (such as air guide angle, swing direction and the like) of the air guide piece. Specifically, the first air guide member is controlled to adjust to an air guide angle corresponding to the first air outlet direction, so that the first air outlet can exhaust air according to the first air outlet direction; and controlling the second air guide member to adjust the air guide angle corresponding to the second air outlet direction so that the second air outlet can output air according to the second air outlet direction, and the air output of the two air outlets can not blow to the position of the target user.
The method is applied to a double-air-channel air conditioner with two air outlets, a first air outlet direction and a second air outlet direction are determined based on position information of a target user in a space where the double-air-channel air conditioner is located, and the first air outlet direction and the second air outlet direction are both air outlet directions capable of avoiding the target user, so that the first air guide piece is controlled to operate according to the first air outlet direction, the second air guide piece is controlled to operate according to the second air outlet direction, a user does not need to operate, air outlets of the two air outlets of the double-air-channel air conditioner can automatically avoid the location of the target user no matter where the user is located, and accordingly comfort of the location of the user is improved.
Further, based on the first embodiment, a second embodiment of the dual air duct air conditioner control method is provided. In the second embodiment, referring to fig. 3, the step S20 includes:
step S21, determining a first detection region in the first air-out region for detecting the position information, and determining a second detection region in the second air-out region for detecting the position information;
the human body detection device for detecting the position information can detect all space areas in the space where the double-air-channel air conditioner is located, and the detection range is the detection range. The part of the detection range, which is overlapped with the first air outlet area, is a first detection area, and the part of the detection range, which is overlapped with the second air outlet area, is a second detection area.
The area of the first detection region is smaller than or equal to the first air outlet region, and the area of the second detection region is smaller than or equal to the second air outlet region.
Step S22, determining a first target area where no target user exists in the first detection area according to the position information, and determining a second target area where no target user exists in the second detection area according to the position information;
specifically, the position of the user in the space can be determined according to the position information. Because the air conditioner is fixedly arranged, the first air outlet area and the second air outlet area are fixed areas. Therefore, whether the target user exists in the first air-out area or not and whether the target user exists in the second air-out area or not can be judged through the position information. Therefore, when the target user is located in the first detection area, the other areas except the area where the target user is located in the first detection area are the first target area; when the target user is not located in the first detection area, the first detection area can be directly used as the first target area; when the target user is located in the first detection area, the other areas except the area where the target user is located in the second detection area are second target areas; when the target user is not located within the second detection area, the second detection area may then directly serve as the second target area.
Step S23, determining the first air outlet direction based on the first target region, and determining the second air outlet direction based on the second target region.
And a direction is selected as a first air outlet direction in the first target area according to a preset rule or at will, and a direction is selected as a second air outlet direction in the second target area according to a preset rule or at will. Because first target area and second target area do not all have the user, consequently first air outlet is difficult to blow directly to the target user according to first air-out direction air-out, and the second air-out district is difficult to blow directly to the target user according to second air-out direction air-out.
Specifically, the direction of the first air outlet facing the central line of the first target area may be determined as a first air outlet direction, and the direction of the second air outlet facing the central line of the second target area may be determined as a second air outlet direction.
In this embodiment, in combination with a detection area formed by covering the detection range corresponding to the position information in the two air outlet areas, a target area where no human body exists is determined in the detection area, and then the air outlet directions corresponding to the two air outlets are respectively determined based on the target area. Because the detection device of the position information generally forms a limited detection area in the space, target users in all the areas can not be detected in the space, and therefore the first air outlet direction and the second air outlet direction exist in the detection area, so that the condition that air conditioner air outlet cannot blow directly to users in the area even if the target users do not exist in other areas in the detection area can be ensured, the accuracy of the first air outlet direction and the second air outlet direction is ensured, and the comfort of the users is effectively ensured.
Further, based on the second embodiment, a third embodiment of the dual air duct air conditioner control method is provided. In a third embodiment, the first detection area and the second detection area are both radial areas with the position of the dual air conditioner as a base point. Because two air outlets of the air conditioner are arranged on the air conditioner body, the air outlet of the air conditioner is blown to the space from the position where the air conditioner is located in a radiation mode. As shown in fig. 4, the large area formed by the areas a to E is the total air outlet area of the dual-duct air conditioner. The total area corresponding to the area A, B, D is a first air-out area, the total area corresponding to the area A, C, E is a second air-out area, the total area corresponding to the area A, B, C is a total detection area corresponding to the position information, the total area corresponding to the area A, B is a first detection area, and the total area corresponding to the area A, C is a second detection area. The midpoint of the connecting line of the two outlets can be used as a base point, such as the point O in fig. 4.
Referring to fig. 5, the step of determining a first target area where no target user exists within the first detection area according to the location information in the step S22 includes:
step S22a, judging whether a target user exists in the first detection area according to the position information;
when the target user does not exist in the first detection region, step S221 is executed, and when the target user exists in the first detection region, step S222, step S223, step S224, and step S225 are executed.
Specifically, the location of the target user is determined according to the location information. There may be one or more based on the amount of location information, and there may also be one or more corresponding to the determined location of the target user. When the determined position exists a position located within the first detection area, indicating that the target user exists in the first detection area; when there is no location within the first detection zone in the determined locations, it is indicated that the target user is not present in the first detection zone.
Step S221, regarding the first detection region as the first target region;
step S222, determining the position of the target user in the first detection area as a first position;
the first position is determined based on the position information. If one target user exists, one position information exists, and one corresponding first position exists; if the target user is more than one, the position information is more than one, and the corresponding first position is more than one.
Step S223, determining a connection line between the first position and the base point as a first area boundary, and determining an area boundary of the first detection area as a second area boundary;
when there is one first position, as shown in point a in fig. 4, Oa is the first area boundary, and since the total area corresponding to the areas a and B is the first detection area, Ox and Oy are the second area boundaries.
When there is more than one first location, such as points a and b in fig. 4, Oa and Ob are the first zone boundaries, and Ox and Oy are the second zone boundaries.
Step S224, dividing the first detection area into a plurality of first to-be-determined areas without target users according to the first area boundary and the second area boundary;
the first area to be determined changes with the number of the first positions, and the larger the number of the first positions, the larger the number of the first area to be determined.
When there is one first position, as shown in point a in fig. 4, two first regions to be determined are correspondingly formed based on three boundaries Oa, Ox, and Oy: xOa area and aOy area, wherein it should be noted that the first area to be determined does not contain the three boundaries Oa, Ox and Oy.
When there are two first positions, as shown in fig. 4 as points a and b, three first regions to be determined are correspondingly formed based on three boundaries Oa, Ob, Ox and Oy: xOb area, bOa area and aOy area, wherein it should be noted that the first area to be determined does not contain three boundaries Oa, Ox and Oy.
Step S225, in the first to-be-determined area, selecting the first target area.
In the first to-be-determined area, an area can be selected as a first target area according to a preset rule or arbitrarily. For example, the first target region may be set to have the largest region range.
Specifically, step S225 includes: acquiring a first angle of a corner part of each first to-be-determined area with the base point as a vertex; and taking the first to-be-determined area corresponding to the maximum first angle as the first target area.
The first angle of each first region to be determined can be obtained by calculating the angle between the boundaries of the two regions forming the region.
When there is one first position, as shown in fig. 4 a, based on the xOa area and the aOy area, the first angle corresponding to the xOa area is α, and the first angle corresponding to the aOy area is β, where α > β, the xOa area is taken as the first target area.
When the first position is more than one, such as points a and b in fig. 4, three first to-be-determined regions, i.e., the xOb region, the bOa region and the aOy region, the first angle corresponding to the xOb region is γ, the first angle corresponding to the bOa region is δ, and the first angle corresponding to the aOy region is β, δ > β, δ > γ, the bOa region is taken as the first target region.
In this embodiment, the first target area is determined in the above manner, no matter where the target user is located in the first air outlet area, no matter how many the number of the target users, a plurality of first to-be-determined areas where the target user does not exist in the first air outlet area are divided based on the location of the target user, and the first target area is determined in the first to-be-determined areas, so that the first air outlet direction determined based on the first target area is accurate, when the first air outlet blows air according to the first air outlet direction, the first air outlet does not blow directly to the location of the target user, and the comfort of the user is improved. Wherein, because the air outlet generally has certain radiation scope when following a certain angle and out wind, adjacent user feels the wind sensation when being nearer easily, consequently regard as first target area the biggest first region of waiting of first angle to guarantee further to reduce the wind sensation that the target user position felt, improve user's travelling comfort.
Further, before the step of using the first to-be-determined area corresponding to the largest first angle as the first target area, the method further includes: judging whether the maximum first angle is larger than or equal to a first preset threshold value or not; when the maximum first angle is larger than or equal to the first preset threshold, executing the step of taking the first to-be-determined area corresponding to the maximum first angle as the first target area; and when the maximum first angle is smaller than the first preset threshold value, controlling the first air guide to continuously adjust the air outlet angle of the first air outlet or controlling the first air guide to operate according to a first preset parameter related to no wind sensation.
The first preset threshold value can be set according to the size of the first air outlet, the air guide characteristics of the first air guide and other specific conditions. The first preset parameter can be specifically determined according to the related operation parameters of the double-air-channel air conditioner when no wind sensation is realized. The first preset threshold value determines the minimum range within which the first air outlet cannot blow the user when the first air outlet is used for directional air outlet. If the largest first angle is smaller than a first preset threshold value, no matter which first to-be-determined area the first air outlet faces, the first to-be-determined area is oriented to discharge air, and obvious wind feeling can be caused to a target user. Therefore, in order to ensure the comfort of the target users, especially more than one target users, located in the first air-out area, the corresponding first to-be-determined area is used as the first target area when the maximum first angle is greater than or equal to the first preset threshold value, and it is ensured that the target users are not directly blown to when the first air-out direction determined based on the first target area is directed to air-out. In addition, when being less than first predetermined threshold value with the biggest first angle, show that no matter which position orientation air-out of first wind guide orientation all can blow the target user directly, consequently continuously sweep the wind through first wind guide to guarantee that wind can not stop too for a long time on the body of the target user, avoid blowing the user directly for a long time, thereby improve all target user's travelling comfort. In addition, the first air guide piece can be controlled to operate according to no wind sensation, for example, the air outlet range of the first air outlet is reduced through the first air guide piece, the direct blowing to a target user is guaranteed not to be achieved through sacrificing of a certain air conditioner heat exchange energy efficiency, and the user is guaranteed to have good body feeling.

step S203, determining a connection line between the second position and the base point as a third area boundary, and determining an area boundary of the second detection area as a fourth area boundary;
step S204, according to the third area boundary and the fourth area boundary, dividing the first detection area into a plurality of second undetermined areas without target users;
step S205, in the second to-be-determined area, selecting the second target area.
Specifically, step S205 includes: acquiring an included angle formed by two area boundaries corresponding to each second undetermined area as a second angle; and taking the second to-be-determined area corresponding to the largest second angle as the second target area.
Specifically, the step of using the second predetermined area corresponding to the largest second angle as the second target area includes: judging whether the maximum second angle is larger than or equal to a second preset threshold value or not; when the maximum second angle is larger than or equal to the second preset threshold, executing the step of taking the second to-be-determined area corresponding to the maximum second angle as the second target area; and when the second angle is smaller than the second preset threshold value, controlling the second air guide to continuously adjust the air outlet angle of the second air outlet or controlling the second air guide to operate according to a second preset parameter related to no wind sensation.
In this embodiment, the specific implementation and technical effects of determining the second target area can be similar to those of the first target area in the third embodiment, and are not described herein again.
When the target user does not exist in the first detection area and the target user exists in the second detection area, and the first air outlet direction is selected in the first target area, the air outlet direction farthest away from the second detection area can be used as the first air outlet direction, so that no wind sensation of the position where the target user is located is ensured, and the comfort of the user is further improved. When the target user does not exist in the second detection area and the target user exists in the first detection area, and the second air outlet direction is selected in the second target area, the air outlet direction farthest away from the first detection area can be used as the second air outlet direction, so that no wind sensation of the position where the target user is located is ensured, and the comfort of the user is further improved.
