[0002] With the development of economy and technology, air conditioners are more and more widely used, and the performance of air conditioners is constantly optimized. Among them, during the air supply process of an air conditioner, the area where the human body is located in the space where the air conditioner acts will be identified, and the air conditioner will supply air towards the area where the human body is located.

[0003] However, when the air conditioner supplies air towards the area where the human body is located, the air conditioner generally detects the number of users in the area and adjusts the air supply parameters of the air conditioner based on the number of users in the area. When the users are the same, the air conditioner will supply air according to the same air supply parameters. This ignores the influence of the heat dissipated by the user himself on other users in the area, and the air volume or cold quantity brought by the air outlet direction of the air conditioner to the area where the human body is located is likely to be too large or too small, which easily leads to the problem of poor comfort of the user.

[0020] Determine the set of all sub-regions corresponding to the target region as the measurement region;

[0021] Determine the area of the measurement region as the area of the region.

[0022] Optionally, the step of determining the sub-region corresponding to each human body position in the target region according to a preset distance includes:

[0023] Determine the circular region corresponding to each human body position in the target region with the human body position as the center and the preset distance as the radius as the sub-region.

[0024] Optionally, the step of determining the sub-region corresponding to each human body position in the target region according to a preset distance includes:

[0025] In a plurality of unit regions, determine the set of all unit regions that meet the target condition as the sub-region corresponding to each human body position in the target region;

[0026] Wherein, the plurality of unit regions are formed by pre-dividing the action space of the air conditioner according to a set area, and the target condition is that the distance between the unit region and the corresponding human body position in the target region is less than or equal to the preset distance.

[0027] Optionally, the number of the target regions is more than one, and the step of controlling the air conditioner to blow air towards the target region according to the air supply duration includes:

[0028] Control the air conditioner to perform a sweeping operation among the target regions;

[0029] During the swing operation of the air conditioner, control the air conditioner to stay for a corresponding air supply duration when blowing air towards each target area.

The air supply duration towards the target area changes with the personnel density in the target area. The personnel density can accurately represent the influence of the heat dissipated by the human body in the target area on the body feeling temperature of each user. Even if the number of people in the target area remains unchanged, but when the personnel density is different, the heat influence brought by other users felt by each user is different, then the air supply duration of the air conditioner towards the target area is different. Based on this, it is ensured that the air volume and heat exchange amount sent into the target area by the air conditioner can be accurately matched with the actual air volume and cooling demand of each user in the target area, and the air supply process of the air conditioner can effectively improve the user comfort.

[0042] The realization of the purpose, functional features and advantages of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0043] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0044] The main solution of the embodiment of the present invention is: obtaining the personnel density in the target area; determining the air supply duration of the target area according to the personnel density; different personnel densities correspond to different air supply durations; controlling the air conditioner to supply air towards the target area according to the air supply duration.

[0045] In the prior art, when the air conditioner supplies air towards the area where the human body is located, the air conditioner generally detects the number of users in the area and adjusts the air supply parameters of the air conditioner based on the number of users in the area. When the users are the same, the air conditioner supplies air according to the same air supply parameters, which ignores the influence of the heat dissipated by the users themselves on other users in the area. The air volume or cold quantity brought by the air outlet direction of the air conditioner to the area where the human body is located is likely to be too large or too small, easily resulting in poor comfort of the users.

[0046] The present invention provides the above solution to accurately send air volume or cold quantity to the area where the user is located and improve the comfort of the user.

[0047] The embodiment of the present invention provides an air conditioner. The air conditioner can be any type of air conditioning device such as a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, a ceiling-mounted air conditioner or a mobile air conditioner.

[0048] Specifically, referring to Figure 1, the air conditioner includes an air outlet regulation component 1 and a control device 2. The air outlet regulation component 1 is connected to the control device. The air outlet regulation component 1 includes an indoor fan 11 and a wind guiding member 12 disposed at the air outlet. The control device 2 can be used to control the operating speed of the indoor fan 11 to regulate the air outlet speed of the air conditioner; the control device 2 can also be used to control the wind guiding angle of the wind guiding member 12 to regulate the air outlet direction of the air conditioner

[0049] Further, in the embodiment of the present invention, refer to Figure 1 , the control device of the air conditioner includes: a processor 1001 (such as a CPU), a memory 1002, a timer 1003, etc. The memory 1002 can be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. Optionally, the memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0050] Specifically, the air conditioner may further include a human body detection module 3, and the human body detection module 3 is specifically used to detect human body information (such as personnel density, human body position, and / or number of people, etc.) in the space where the air conditioner acts. In this embodiment, the human body detection module 3 is a radar sensor; in other embodiments, the human body detection module 3 can also be an infrared sensor, a camera, etc. The human body detection module 3 can be connected to the control device 2, and the control device 2 can be used to obtain the data detected by the human body detection module 3.

[0051] Those skilled in the art can understand that Figure 1 the device structure shown in does not constitute a limitation on the device, and may include more or fewer components than shown, or combine some components, or arrange different components.

[0052] Such as Figure 1 shown, the memory 1002 as a computer-readable storage medium may include a control program of the air conditioner. In Figure 1 the device shown, the processor 1001 can be used to call the control program of the air conditioner stored in the memory 1002 and execute the relevant step operations of the air conditioner control method in the following embodiments.

[0053] The embodiment of the present invention also provides an air conditioner control method, which is applied to regulate the above-mentioned air conditioner.

[0054] Refer to Figure 2 , and an embodiment of the air conditioner control method of the present application is proposed. In this embodiment, the air conditioner control method includes:

[0055] Step S10, obtain the personnel density in the target area;

[0056] The personnel density specifically refers to the number of personnel per unit area in the target area. The personnel density can be determined by obtaining the detection data of the human body detection module, or by obtaining the information input by the user himself / herself (for example, the user can input the number of people and the area in the target area through the control device of the air conditioner or the terminal connected to the air conditioner and installed with a preset application).

[0057] The target area can be a preset fixed area, or an area determined based on the actual situation of the personnel in the action space of the air conditioner (such as the area characteristics of the area where the personnel are located (such as near the kitchen or near the toilet, etc.), the personnel position, whether there are other air conditioning devices at the position where the human body is located, etc.), or a designated area set by the user.

[0058] The number of target areas can be one, or more than one. When there are more than one target areas, the areas of different target areas can be the same or different. Specifically, in this embodiment, the area of the target area increases with the increase in the number of people in the target area. Among them, when the number of target areas is more than one, the personnel density of each target area is obtained respectively.

[0059] Step S20, determine the air supply duration of the target area according to the personnel density; different personnel densities correspond to different air supply durations;

[0060] The air supply duration here specifically refers to the duration required for the air conditioner to supply air towards the target area. Specifically, in this embodiment, the air supply duration increases with the increase in the personnel density; conversely, the air supply duration decreases with the decrease in the personnel density. In other embodiments, the air supply duration may also decrease with the increase in the personnel density.

[0061] Specifically, a corresponding relationship between the personnel density and the air supply duration can be established in advance. This corresponding relationship can be a calculation formula, a mapping table, an algorithm model, etc. When the corresponding relationship is a preset formula, the air supply duration can be calculated by substituting the personnel density into the preset formula; when the corresponding relationship is a mapping table, the air supply duration can be obtained by querying the mapping table with the personnel density and using the result obtained by querying and matching as the air supply duration; when the corresponding relationship is an algorithm model, the personnel density can be input into the algorithm model and the result output by the algorithm model can be used as the air supply duration.

[0062] It should be noted that when the number of target areas is more than one, the air supply duration of each target area is determined respectively according to the personnel density corresponding to each target area. Different personnel densities corresponding to different target areas result in different air supply durations for the target areas. Each target area corresponds to an air supply duration. Among them, the total duration corresponding to the air supply durations of all target areas can be a preset duration. Based on this, the target ratio (the ratio of the air supply duration in the preset duration) corresponding to each target area can be determined according to the personnel density corresponding to each target area. The greater the personnel density, the greater the target ratio. The air supply duration of each target area is calculated according to the preset duration and the target ratio corresponding to each target area. For example, the first target area corresponds to the first ratio, the second target area corresponds to the second ratio. The first air supply duration corresponding to the first target area is the product of the preset duration and the first ratio, and the second air supply duration corresponding to the second target area is the product of the preset duration and the second ratio.

[0063] Step S30: Control the air conditioner to supply air towards the target area according to the air supply duration.

[0064] Control the air conditioner to supply air towards the target area. When the continuous duration of the air conditioner supplying air towards the target area reaches its corresponding air supply duration, the air conditioner stops supplying air towards the target area. When the air conditioner stops supplying air towards the target area, the air conditioner can be shut down or supply air towards other areas outside the target area.

[0065] In this embodiment, the air conditioner operates in a refrigeration mode or a heating mode during the process of supplying air towards the target area. In other embodiments, the air conditioner can also operate in a dehumidification mode, a humidification mode, or a blowing mode (without temperature adjustment function), etc. during the process of supplying air towards the target area.

[0066] Among them, when the number of target areas is more than one, the air conditioner supplies air towards the corresponding target areas respectively according to each air supply duration. Specifically, in this embodiment, the number of target areas is more than one, and the air conditioner is controlled to perform a sweeping operation among the target areas; during the sweeping operation of the air conditioner, the air conditioner is controlled to supply air towards each target area for a corresponding air supply duration. For example, there are area A, area B, and area C in sequence from left to right within the action space of the air conditioner. The air supply duration corresponding to area A is T1, the air supply duration corresponding to area B is T2, and the air supply duration corresponding to area C is T3. Based on this, the air conditioner performs a sweeping operation from left to right, and when its air outlet reaches area A, it maintains supplying air towards area A for a duration of T1, when its air outlet reaches area B, it maintains supplying air towards area B for a duration of T2, and when its air outlet reaches area C, it maintains supplying air towards area C for a duration of T3.

[0067] A control method for an air conditioner proposed in an embodiment of the present invention. This method determines the air supply duration for the air conditioner to supply air towards a target area in combination with the personnel density in the target area. The air supply duration towards the target area changes with the change of the personnel density in the target area. The personnel density can accurately represent the influence of the heat dissipated by the human body in the target area on the perceived temperature of each user. Even if the number of people in the target area remains unchanged, but when the personnel density is different, the heat influence brought by other users felt by each user is different, then the air supply duration of the air conditioner towards the target area is different. Based on this, it is ensured that the air volume and heat exchange amount sent into the target area by the air conditioner can be accurately matched with the actual air volume and cooling demand of each user in the target area, and the air supply process of the air conditioner can effectively improve the user comfort.

[0068] Further, based on the above embodiment, another embodiment of the control method of the air conditioner of the present application is proposed. In this embodiment, before step S10, it further includes: Figure 3 ,Before the step S10, it further includes:

[0069] Step S01, obtaining the body positions of each person in the space where the air conditioner acts;

[0070] In this embodiment, the data detected by the radar sensor built in the air conditioner is obtained, and the body positions of each person in the space are determined according to the data detected by the radar sensor.

[0071] Wherein, when the number of people in the space where the air conditioner acts is one, the number of the obtained body positions is one; when the number of people in the space where the air conditioner acts is more than one, the number of the obtained bodies is more than one.

[0072] Step S02, determining the distance between any two of the obtained body positions among the obtained several body positions;

[0073] Specifically, when the number of the obtained body positions is more than one, the body positions more than one are combined in pairs, and the distance between the two body positions in each combination is determined.

[0074] Step S03, connecting the two body positions with the distance less than or equal to the set distance threshold to form a sub-region, and obtaining several sub-regions;

[0075] Step S04, determining the region where the several sub-regions are connected as the target region.

[0076] Wherein, if there are more than one connected regions among the several sub-regions, more than one target region can be obtained. When more than one target region is obtained, the human density in each target region can be determined, and the air supply duration for each target region can be determined correspondingly according to the human density, and the air conditioner is controlled to supply air towards different target regions in sequence according to the determined air supply duration.

[0077] Specifically, referring to Figure 4 , Figure 4 each circle in represents a human body position. The distance values between each human body position and all other human body positions are calculated respectively. Two human body positions with all distance values less than the set distance threshold are connected. Each connected area in the figure is a target area. Each human body position represents a human body, and each target area represents a group of people. Based on this, Figure 4 it is shown in that 13 people can be divided into 5 groups of people.

[0078] In this embodiment, based on the human body positions in the action space of the air conditioner, indoor users are divided into different groups of people. Based on the positions where the groups of people are located, the target areas where the air conditioner needs to supply air are determined. Based on this, it can be ensured that the air supply of the air conditioner can be accurately matched with the actual aggregation situation of indoor people, and it can be avoided that the air supply area divided according to the preset fixed rules does not match the actual situation of indoor people, resulting in poor air feeling and hot and cold feeling for some users. Furthermore, the accuracy of the air supply regulation of the air conditioner is improved to further improve the comfort of each user.

[0079] Furthermore, based on any of the above embodiments, another embodiment of the control method of the air conditioner of the present application is proposed. In this embodiment, the step of obtaining the population density in the target area includes:

[0080] Step S11, obtain the number of people in the target area and obtain the area of the target area;

[0081] The number of people here can be input by the user himself, or determined based on the detection data of the human body detection module built in the air conditioner. In this embodiment, obtain the human body detection data, and determine according to the human body detection data

[0082] When the target area is a preset fixed area, the area data stored in advance for this area can be read as the area here. When the target area is an area divided based on the actual situation of the people in the action space of the air conditioner, the area of the target area can be calculated based on the division result to obtain the area here.

[0083] Step S12, determine the population density according to the ratio of the number of people and the area of the area.

[0084] Specifically, the ratio can be directly used as the population density; or the result after correcting the ratio according to the set correction value can be used as the population density. In this embodiment, define the population density as J, the number of people as N, and the area of the area as S, then J = N / S.

[0085] In this embodiment, by obtaining the personnel data and the area of the area, the population density in the target area can be accurately obtained, thereby ensuring the accuracy of determining the air supply duration of the target area subsequently.

[0086] Specifically, in this embodiment, referring to Figure 5 , defining obtaining the number of people in the target area as step S111, the step of obtaining the area of the target area includes:

[0087] Step S101, determining a sub-area corresponding to each human body position in the target area according to a preset distance; the distance between the position in the sub-area and the corresponding human body position is less than or equal to the preset distance;

[0088] The preset distance can be a preset fixed distance value or a value obtained based on the indoor environmental temperature. Each human body position corresponds to a sub-area, and the maximum distance between the position in each sub-area and its corresponding human body position does not exceed the preset distance. The sub-area can be a polygonal area, a circular area, a square area or an irregularly shaped area.

[0089] In one implementation manner of this embodiment, in combination with Figure 6 , a circular area corresponding to each human body position in the target area is determined with the human body position as the center and the preset distance as the radius as the sub-area. When the number of target areas is more than one, each target area can determine the sub-areas corresponding to the human body positions therein in this manner. Specifically, Figure 6 Each dotted area in represents a sub-area corresponding to a human body position. If there are 4 human body positions in target area A, then 4 sub-areas are correspondingly obtained; if there are 3 human body positions in target area E, then 3 sub-areas are correspondingly obtained. Based on this, the area of the target area can be accurately represented based on the areas of the sub-areas corresponding to each human body position in each target area, ensuring that the personnel density of the target area can be accurately obtained subsequently, realizing the air supply duration determined based on the personnel density, and accurately regulating the process of the air conditioner blowing air towards the target area, effectively improving the comfort of users in the target area.

[0090] In another implementation manner of this embodiment, in combination with Figure 7 , in multiple unit areas, a set of all unit areas that meet the target conditions is determined as the sub-area corresponding to each human body position in the target area; wherein, the multiple unit areas are formed by dividing the action space of the air conditioner in advance according to a set area, and the target condition is that the distance between the unit area and the corresponding human body position in the target area is less than or equal to the preset distance. The set area can set its value according to actual accuracy requirements. As Figure 7 shown, Figure 7A square area within it is a unit area, and the circle represents the human body position. Based on this, the polygon area formed by the set of all square areas within the target area A whose distance from each human body position is less than or equal to a preset distance is the sub-area corresponding to that human body position. By determining the sub-areas corresponding to each human body position within the target area in this way, approximate calculation of the area where the human body is located can be achieved based on the unit area, thereby realizing automatic recognition of the area where the user is located, enabling the air conditioner to calculate the human body density of the area based on the area of the determined target area, and enabling the air conditioner to adapt to the personnel density within the target area for air supply, effectively improving the comfort of users within the target area.

[0091] Step S102, determine the set of all sub-areas corresponding to the target area as the measurement area;

[0092] Step S103, determine the area of the measurement area as the area of the region.

[0093] As Figure 6 and Figure 7 shown, each shaded area is a measurement area, and the area of each calculation area is the area of the corresponding target area.

[0094] Specifically, based on Figure 6 the determination method of the corresponding measurement area, the union of all circular dotted areas corresponding to the target area is the measurement area. By calculating the total area of all circular dotted areas corresponding to the target area and the overlapping area of the overlapping areas in all circular dotted areas corresponding to the target area, the result obtained by subtracting the overlapping area from the total area is the area of the region corresponding to the target area. When the number of target areas is more than one, each target area can be calculated in this way.

[0095] Specifically, based on Figure 7 the determination method of the corresponding measurement area, the space is evenly divided into squares with the same area size (for example, each square is 0.01m 2 ), the union of all squares corresponding to the target area is the measurement area. By determining the number of squares within the measurement area, the area of the region corresponding to the target area can be calculated based on the product of the determined number and the set area corresponding to the square. When the number of target areas is more than one, each target area can be calculated in this way. For example, when the distance from the center coordinate of each square to any person in the crowd is less than the preset value (0.5m), then this square is the area where the crowd is located, as Figure 7Among them, the area of crowd A is 57 grids, the area of crowd B is 37, the area of crowd C is 57 grids, the area of crowd D is 18, and the area of crowd E is 52 grids. Then the crowd aggregation degrees of A, B, C, D, and E are respectively, 4 / 57 = 0.070, 2 / 37 = 0.054, 3 / 57 = 0.053, 1 / 18 = 0.055, 3 / 52 = 0.058.

[0096] In this embodiment, through the above method, it is possible to realize the area of the target region occupied by the crowd where the human body is located automatically recognized by the air conditioner based on the human body position in the space. Regardless of the degree of crowding of the people in the space, the human body density representing the degree of crowding can be obtained based on the automatically recognized area. When the air conditioner blows air towards the crowd, the air supply duration can be matched with the degree of personnel density in this region, effectively improving the comfort of each user in the crowd.

[0097] Further, based on any of the above embodiments, during the execution of step S30, it further includes: controlling the operation of the air conditioner according to the target air supply wind speed, where the target air supply wind speed is determined according to the personnel density corresponding to the target region, and the target air supply wind speed shows an increasing trend as the personnel density increases. On the contrary, the target air supply wind speed shows a decreasing trend as the personnel density decreases.

[0098] Specifically, the corresponding relationship between the human body density and the target air supply wind speed can be preset, which can be in the form of a calculation formula, a mapping relationship, etc. Based on this corresponding relationship, the target air supply wind speed corresponding to the current human body density can be determined.

[0099] Further, in order to further improve the air supply effect, there can be more than one preset corresponding relationship between the human body density and the target air supply wind speed. Based on this, after determining the air supply duration of the target region based on the personnel density, one of them can be selected as the target corresponding relationship among the more than one corresponding relationships between the human body density and the target air supply wind speed based on the air supply duration. Different air supply durations correspond to different target corresponding relationships. Based on the target corresponding relationship, the target air supply wind speed corresponding to the current human body density can be determined.

[0100] In this embodiment, while controlling the air conditioner to blow air towards the corresponding target region according to the determined air supply duration, the operation of the air conditioner is controlled based on the target air supply wind speed determined by the human body density, so as to ensure that the air supply volume and the blowing feeling in the target region can be accurately matched with the personnel situation through the cooperation of the duration and the wind speed, further improving the blowing comfort of the users in the target region.

[0101] In addition, an embodiment of the present invention further provides a computer-readable storage medium, on which a control program of an air conditioner is stored. When the control program of the air conditioner is executed by a processor, the relevant steps of any one of the above-described control methods of the air conditioner are implemented.
