Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a control method, device and readable storage medium for an air conditioner. Background Art

[0002] With the advancement of technology, air conditioners have become ubiquitous and a part of daily life. Currently, bedroom air conditioners are equipped with various smart sensors. In particular, smart air conditioners designed for children's sleep monitoring are equipped with infrared thermal imaging sensors, which can adjust the air conditioning mode based on the child's sleep status. However, when applied to multi-person scenarios, existing detection and control methods can only adjust the air supply level based on parameters such as each person's height. For hyperactive children, whose sleeping positions and body orientations change frequently, using the same air supply level can result in poor comfort. Summary of the Invention

[0003] The problem solved by the present invention is that the existing air conditioner cannot adjust the comfortable blowing state according to the body orientation of each child in the children's room.

[0004] To solve the above problems, the present invention provides a control method and device for an air conditioner and a readable storage medium.

[0005] On the one hand, the present invention provides a method for controlling an air conditioner, the method comprising: step S1: turning on a multi-child wind sweeping mode; step S2: detecting the position of each child's head and foot relative to the air conditioner, and obtaining the wind sweeping angle formed by the wind sweeping plate of the air conditioner when passing through each child based on the position of each child's head and foot relative to the air conditioner; and step S3: setting the angular velocity of the wind sweeping plate of the air conditioner when passing through each wind sweeping angle based on the angle of each wind sweeping angle.

[0006] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: according to the position of the child's head and feet relative to the air conditioner, the angle at which the child can actually obtain air conditioning, that is, the size of the sweeping angle, can be determined. The larger the sweeping angle, the longer the child can obtain air conditioning during the sweeping process, and the smaller the sweeping angle, the shorter the child can obtain air conditioning during the sweeping process. Therefore, by adjusting the angular velocity of the air sweep plate of the air conditioner through each sweeping angle according to the size of the sweeping angle, children sleeping in any direction can obtain a comfortable blowing effect.

[0007] Furthermore, the step S2 further includes: obtaining a first distance L1 of each child's head relative to the air conditioner and a second distance L2 of each child's foot relative to the air conditioner according to the position of each child's head and foot relative to the air conditioner, and calculating an average distance L of the first distance L1 and the second distance L2. mThe step S3 further comprises: according to the average value L of the distance m , set the first air volume P1 of the air sweeping plate of the air conditioner passing through each of the air sweeping angles.

[0008] The technical effect achieved by adopting this technical solution: the average distance L between the child's head and feet relative to the air conditioner m Different, the required air volume is also different; the distance from the average value L m The larger the first air volume P1 is, the larger the first air volume P1 is used, so that children far away can also get a relatively comfortable blowing effect, while the smaller the first air volume P1 is, the less likely nearby children will get cold and their health will be affected.

[0009] Furthermore, step S2 also includes: determining the relationship between a first distance L1 of each child's head relative to the air conditioner and a second distance L2 of the child's feet relative to the air conditioner; step S3 also includes: if |L1-L2|≤K1, maintaining the first air volume; if L1-L2>K1, increasing the first air volume; if L2-L1>K1, reducing the first air volume; wherein K1 is the distance difference threshold.

[0010] The technical effect achieved by adopting this technical solution: by comparing the size relationship between the first distance L1 of the child's head relative to the air conditioner and the second distance L2 of the child's feet relative to the air conditioner, the child's sleeping direction can be reflected. Adjusting the air volume according to the direction of the child's head can further improve comfort and avoid direct blowing of the head at a high wind speed, which affects physical health; wherein, a distance difference threshold K1 is set to avoid the situation where the first distance L1 and the second distance L2 cannot always reach equal values, and the air conditioner repeatedly adjusts the first air volume, thereby wasting energy.

[0011] Furthermore, the control method of the air conditioner also includes: step S4: determining whether there is an overlapping area among the sweeping angles, and if so, adjusting the second air volume P2 in the overlapping area according to the first air volume P1 of the multiple overlapping sweeping angles.

[0012] The technical effect achieved by adopting this technical solution is: when there is an overlapping area of ​​the wind sweeping angle, that is, multiple children can be blown at the same time in this direction of the air conditioner, then changing the air volume can ensure that each child in this direction can get a suitable blowing effect.

[0013] Furthermore, the step S4 also includes: if the overlapping area only includes the child's head, the second air volume P2 takes the minimum value of the first air volume P1 of the multiple overlapping wind sweeping angles; if the overlapping area includes both the head of any child and the feet of any child, the second air volume P2 takes the average value of the first air volume P1 of the multiple overlapping wind sweeping angles; if the overlapping area only includes the child's feet, the second air volume P2 takes the maximum value of the first air volume P1 of the multiple overlapping wind sweeping angles.

[0014] The technical effects achieved by adopting this technical solution are: children's heads are more sensitive to cold air. In the overlapping area, when the air conditioner blows on the heads of multiple children at the same time, the second air volume P2 takes the minimum value of the first air volume P1 to prevent any child from getting cold; when the air conditioner blows on any child's head and any child's feet at the same time, the second air volume P2 takes the average value of the first air volume P1 to take into account both health and comfort; when the air conditioner blows on the feet of multiple children at the same time, the second air volume P2 takes the maximum value of the first air volume P1 to effectively ensure comfort.

[0015] Furthermore, the step S3 also includes: calculating the ratio of the inverses of the angles of each of the sweeping angles according to the angles of each of the sweeping angles, and obtaining the ratio of the angular velocities of the sweeping plates of the air conditioner passing through each of the sweeping angles; determining the initial value of the angular velocity according to the windshield of the air conditioner, and determining the angular velocity of the sweeping plates corresponding to each of the sweeping angles according to the initial value of the angular velocity and the ratio of the angular velocity.

[0016] The technical effects achieved by adopting this technical solution are as follows: the angular velocity ratio of the sweep plate passing through the sweep angle is determined according to the ratio of the inverse of the sweep angle, so that the sweep plate of the air conditioner can stay at each sweep angle for the same time, ensuring that children corresponding to each sweep angle can obtain sufficient blowing effect; the initial value of the angular velocity is determined according to the wind gear, so that the angular velocity of the sweep plate corresponding to each sweep angle can be adjusted according to the actual cooling or heating needs, which is more flexible.

[0017] Furthermore, the step S2 also includes: performing facial recognition on each child; the step S3 also includes: adjusting the angular velocity of the air sweeping plate of the air conditioner passing through each of the air sweeping angles according to the preset air blowing preferences of each child.

[0018] The technical effect achieved by adopting this technical solution is: the angular velocity of the air sweeping plate is further adjusted according to the children's blowing preferences, which can further improve the comfort of the air conditioner when blowing directly on the children.

[0019] Furthermore, the control method of the air conditioner also includes: step S5: judging whether there is a gap area between each of the sweeping angles, the third air volume P3 of the air conditioner in the gap area is the smaller of the first air volumes P1 of the two adjacent sweeping angles in the gap area.

[0020] The technical effect achieved by adopting this technical solution is: continuous blowing of air in the gap area between the sweeping angles can avoid significant temperature fluctuations in the children's room; and the third air volume P3 of the air conditioner in the gap area takes the smaller of the first air volumes P1 of the two adjacent sweeping angles, which can effectively save energy.

[0021] On the other hand, the present invention also provides a control device for an air conditioner, which is used to implement the control method for an air conditioner provided in any of the above embodiments, and the control device for the air conditioner includes: a detection module, which is used to turn on the multi-child sweeping mode, detect the position of each child's head and feet relative to the air conditioner, and obtain the sweeping angle formed by the sweeping plate of the air conditioner when passing through each child according to the position of each child's head and feet relative to the air conditioner; and a control module, which is used to set the time ratio of the sweeping plate of the air conditioner passing through each sweeping angle according to the angle of each sweeping angle.

[0022] The technical effect achieved by adopting this technical solution is as follows: the detection module detects the position of the child's head and feet relative to the air conditioner, and can determine the angle at which the child can actually obtain air from the air conditioner, as well as the distance between the child and the air conditioner; the control module adjusts the angular velocity of the air sweeping plate of the air conditioner through each air sweeping angle according to the angle of the air sweeping angle, so that children sleeping in any direction can get a comfortable blowing effect, and ensure that children who are far away can also get a good blowing experience.

[0023] On the other hand, the present invention further provides a readable storage medium, wherein the readable storage medium stores a computer program, and when the computer program is read and executed by a processor, the air conditioner control method provided in any of the above embodiments is implemented.

[0024] The technical effect achieved by adopting this technical solution is: the readable storage medium is used to store the computer program, which can be run on different air conditioners to implement the control method of the air conditioner to achieve the same effect.

[0025] In summary, the above-mentioned embodiments of the present application may have one or more of the following advantages or beneficial effects: i) According to the position of the child's head and feet relative to the air conditioner, the angle at which the child can actually obtain air from the air conditioner, the distance between the child and the air conditioner, and the direction in which the child sleeps can be determined.

[0030] The object of the present invention is to provide a control method and device for an air conditioner, which can set a comfortable blowing state according to the body orientation and position of each child in a children's room.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] On the one hand, see Figure 1 A first embodiment of the present invention provides a method for controlling an air conditioner, the method comprising:

[0033] Step S1: Turn on the multi-child wind sweeping mode;

[0034] Step S2: detecting the position of each child's head and foot relative to the air conditioner, and obtaining the sweep angle formed by the air sweep plate of the air conditioner when passing each child based on the position of each child's head and foot relative to the air conditioner;

[0035] Step S3: According to the angles of the respective sweeping angles, the angular velocity of the sweeping plate of the air conditioner passing through the respective sweeping angles is set.

[0036] In this embodiment, the angle at which the child can actually receive air from the air conditioner, that is, the size of the sweeping angle, can be determined based on the position of the child's head and feet relative to the air conditioner. The larger the sweeping angle, the longer the child will receive air from the air conditioner during the sweeping process, and the smaller the sweeping angle, the shorter the child will receive air from the air conditioner during the sweeping process. Therefore, by adjusting the angular velocity of the air sweep plate of the air conditioner through each sweeping angle according to the size of the sweeping angle, children sleeping in any direction can get a comfortable blowing effect.

[0037] Preferably, in step S1, the user can send a command to the air conditioner by operating a control terminal such as a remote control or a smart phone to turn on the multi-child sweeping mode. Of course, the state of the child can also be detected by a detection device such as an infrared sensor. When the child in the child room is in a static lying position for a period of time, the multi-child sweeping mode is automatically turned on. This is not limited here.

[0038] Preferably, in step S2, a three-dimensional 3D image of the indoor target is acquired, for example, by using a TOF sensor, so as to determine the position of each child's head and feet relative to the air conditioner.

[0039] In a specific embodiment, step S2 further includes, for example, obtaining a first distance L1 of each child's head relative to the air conditioner and a second distance L2 of each child's foot relative to the air conditioner based on the position of each child's head and foot relative to the air conditioner, and calculating an average distance L of the first distance L1 and the second distance L2. m ; Step S3 also includes: according to the distance average L m , set the first air volume P1 of the air sweeping plate of the air conditioner passing through each air sweeping angle.

[0040] It should be noted that the average distance L between the head and feet of a child is m The required air volume is different. m The larger the first air volume P1 is, the larger the first air volume P1 is used, so that children far away can also get a relatively comfortable blowing effect, while the smaller the first air volume P1 is, the less likely nearby children will get cold and their health will be affected.

[0041] Of course, we can also use image methods to obtain more feature points of each child, such as waist, palm, elbow, knee, etc., calculate the distance from each feature point to the air conditioner, as well as the distance from the child's head and feet to the air conditioner, and take the average value of all the above data as the distance average L m , so that when the child is in a curled up state or other state, the average distance L that can more accurately reflect the distance between the child and the air conditioner is obtained m , making the results more accurate.

[0042] In a specific embodiment, step S2, for example, also includes: determining the relationship between the first distance L1 of each child's head relative to the air conditioner and the second distance L2 of the feet relative to the air conditioner; step S3 also includes: if |L1-L2|≤K1, maintaining the first air volume; if L1-L2>K1, increasing the first air volume; if L2-L1>K1, reducing the first air volume; wherein K1 is the distance difference threshold.

[0043] It should be noted that comparing the first distance L1 between a child's head and the air conditioner and the second distance L2 between a child's feet and the air conditioner can reflect the child's sleeping orientation. Adjusting the air volume based on the orientation of the child's head can further improve comfort and avoid high wind speeds blowing directly on the head, which can affect physical health. The distance difference threshold K1 is set to prevent the air conditioner from repeatedly adjusting the first air volume when the first distance L1 and the second distance L2 cannot always reach the same value, thereby wasting energy.

[0044] In a specific embodiment, the air conditioner control method further includes: step S4: determining whether there is an overlapping area among the sweep angles; if so, adjusting the second air volume P2 in the overlapping area according to the first air volume P1 of the overlapping sweep angles.

[0045] It should be noted that when there is an overlapping area of ​​the wind sweep angle, that is, multiple children can be blown at the same time in this direction of the air conditioner, then changing the air volume can ensure that each child in this direction can get a suitable blowing effect.

[0046] In a specific embodiment, step S4 also includes, for example: if the overlapping area only includes the child's head, the second air volume P2 takes the minimum value of the first air volume P1 of the multiple overlapping sweeping angles; if the overlapping area includes both the head of any child and the feet of any child, the second air volume P2 takes the average value of the first air volume P1 of the multiple overlapping sweeping angles; if the overlapping area only includes the child's feet, the second air volume P2 takes the maximum value of the first air volume P1 of the multiple overlapping sweeping angles.

[0047] It should be noted that children's heads are more sensitive to cold air. In the overlapping area, when the air conditioner blows on the heads of multiple children at the same time, the second air volume P2 takes the minimum value of the first air volume P1 to prevent any child from getting cold; when the air conditioner blows on the head and feet of any child at the same time, the second air volume P2 takes the average value of the first air volume P1 to take into account both health and comfort; when the air conditioner blows on the feet of multiple children at the same time, the second air volume P2 takes the maximum value of the first air volume P1 to effectively ensure comfort.

[0048] In a specific embodiment, step S3, for example, also includes: calculating the ratio of the inverse of the angles of each sweep angle according to the angle of each sweep angle, and obtaining the angular velocity ratio of the sweep plate of the air conditioner passing through each sweep angle; determining the initial angular velocity value according to the windshield of the air conditioner, and determining the angular velocity of the sweep plate corresponding to each sweep angle according to the initial angular velocity value and the angular velocity ratio.

[0049] It should be noted that, by determining the angular velocity ratio of the sweep plate passing through the sweep angle according to the ratio of the inverse of the sweep angle, the sweep plate of the air conditioner can stay at each sweep angle for the same time, ensuring that the children corresponding to each sweep angle can get sufficient blowing effect; the initial value of the angular velocity is determined according to the wind gear, so that the angular velocity of the sweep plate corresponding to each sweep angle can be adjusted according to the actual cooling or heating needs, which is more flexible.

[0050] Preferably, the larger the wind gear is, the higher the user's demand for cooling or heating. At this time, the angular velocity of the wind sweep plate corresponding to each wind sweep angle is further reduced, thereby increasing the blowing time and improving the comfort under cooling or heating; on the contrary, the smaller the wind gear is, the lower the user's demand for cooling or heating. At this time, the angular velocity of the wind sweep plate corresponding to each wind sweep angle is further increased, thereby reducing the blowing time and also improving the comfort under cooling or heating.

[0051] In one specific embodiment, step S4 further includes determining whether there is an overlapping area between the sweep angles. If so, when the sweep plate is in the overlapping area, its angular velocity is the minimum of the sweep plate angular velocities corresponding to the overlapping sweep angles. For example, if n children are being blown simultaneously in any direction of the air conditioner, the angular velocity of the sweep plate in the overlapping area corresponding to the n children is the minimum of the n sweep plate angular velocities corresponding to the n sweep angles. In this case, the sweep plate's blowing time in the overlapping area is maximized, while also preventing excessive blowing, thereby improving comfort.

[0052] In a specific embodiment, step S2 may further include: performing facial recognition on each child; and step S3 may further include: adjusting the angular velocity of the air sweep plate of the air conditioner through various air sweep angles based on the preset air blowing preferences of each child. It should be noted that further adjusting the angular velocity of the air sweep plate based on the child's air blowing preferences can further improve the comfort of the air conditioner when blowing directly on the child.

[0053] For example, when any child likes to blow wind, the angular velocity of the wind sweeping plate corresponding to the wind sweeping angle at which the child is located is multiplied by a coefficient x1, where x1 is a constant between 0.5 and 1; when any child does not like to blow wind, the angular velocity of the wind sweeping plate corresponding to the wind sweeping angle at which the child is located is multiplied by a coefficient x2, where x2 is a constant between 1 and 2.

[0054] In a specific embodiment, the control method of the air conditioner also includes: step S5: determining whether there is a gap area between each sweep angle, and the third air volume P3 of the air conditioner in the gap area is the smaller of the first air volumes P1 of the two adjacent sweep angles in the gap area.

[0055] It should be noted that continuous blowing of air in the gap area between the sweep angles can avoid significant temperature fluctuations in the children's room; and the third air volume P3 of the air conditioner in the gap area takes the smaller of the first air volumes P1 of the two adjacent sweep angles, which can effectively save energy.

[0056] On the other hand, see Figure 2 The second embodiment of the present invention further provides a control device for an air conditioner, which is used to implement the control method for an air conditioner provided in any of the above embodiments. The control device for the air conditioner includes: a detection module 110, which is used to turn on the multi-child sweeping mode, detect the position of each child's head and feet relative to the air conditioner, and obtain the sweeping angle formed by the sweeping plate of the air conditioner when passing through each child according to the position of each child's head and feet relative to the air conditioner; and a control module 1120, which is used to set the time ratio of the sweeping plate of the air conditioner passing through each sweeping angle according to the angle of each sweeping angle.

[0057] It should be noted that the detection module 110 detects the position of the child's head and feet relative to the air conditioner, and can determine the angle at which the child can actually receive air from the air conditioner, as well as the distance between the child and the air conditioner; the control module 1120 adjusts the angular velocity of the air sweeping plate of the air conditioner through each air sweeping angle according to the angle of the air sweeping angle, so that children sleeping in any direction can get a comfortable blowing effect, and ensure that children who are far away can also get a good blowing experience.

[0058] In a specific embodiment, the third embodiment of the present invention further provides a readable storage medium, which stores a computer program. When the computer program is read and executed by a processor, the control method of the air conditioner provided in any of the above embodiments is implemented.

[0059] It should be noted that the readable storage medium is used to store the computer program, which can be run on different air conditioners to implement the control method of the air conditioner to achieve the same effect.

[0060] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
