[0035] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0037] The operating principle of the air conditioner involved in the embodiment of the present application is described in detail below:

[0038] like Figure 1As shown in the figure, the compressor compresses the refrigerant (coolant) and transports it to the condenser through a pipeline. The high-temperature and high-pressure gaseous refrigerant releases heat in the condenser and becomes a medium-temperature and high-pressure liquid refrigerant. After that, the medium-temperature and high-pressure liquid refrigerant is depressurized by a capillary tube (throttling unit) and becomes a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant is transported to the evaporator to evaporate from liquid to gas, and absorbs a large amount of heat during the evaporation process. Finally, the low-temperature and low-pressure gaseous refrigerant in the evaporator is transported to the compressor to participate in the next cycle. When the air conditioner is cooling, the heat exchanger of the outdoor unit is the condenser, and the heat exchanger of the indoor unit is the evaporator; conversely, when the air conditioner is heating, the heat exchanger of the outdoor unit is the evaporator, and the heat exchanger of the indoor unit is the condenser.

[0039] The following is a description of the professional terms involved in the embodiments of the present application:

[0040] Millimeter wave radar: It is a new type of wireless communication technology that has developed rapidly in recent years and is also widely used in human body detection. Millimeter wave radar technology transmits millimeter wave signals to the target object and receives its echo signal. It uses the slight changes in weak signals to extract relevant information of the target object, thereby achieving non-contact and non-invasive measurement and identification of the object.

[0041] Based on the above characteristics of millimeter wave radar, its application in human body detection includes the following aspects:

[0042] Health monitoring: By detecting physiological parameters such as heartbeat, breathing, and body temperature, it is used for health monitoring and disease prevention. For example, in the medical field, the patient's heart or breathing power can be monitored by millimeter-wave radar, which can allow doctors to understand the patient's health status more accurately.

[0043] Posture recognition: By detecting and recognizing human posture, it can be further applied to the fields of human motion analysis and posture correction, which is of great help to people's physical health and exercise effect. For example, in a gym, millimeter-wave radar can be used to detect whether the athlete's posture is correct, so as to correct the athlete's wrong posture and reduce sports injuries.

[0044] Human safety detection: Millimeter-wave radar can perform security checks on the human body, identify and detect dangerous goods and thermal energy materials, etc., such as timely discovering people carrying dangerous goods in airports and large public places to ensure safety. In addition, when it detects that the human body is in poor condition, the millimeter-wave radar can also automatically send a signal to emergency personnel to obtain emergency help.

[0045] In short, millimeter wave radar has many applications in human body detection, which can effectively improve people's quality of life and ensure human safety. Due to the development of millimeter wave radar technology, future applications will also be more extensive and diversified.

[0046] Compared with traditional infrared sensors, millimeter wave radar has the following advantages:

[0047] Low false touch, wide range: Compared with infrared sensor trigger, it reduces the false touch rate and breaks the limitations of mobile monitoring. Millimeter wave radar can realize the presence perception, trajectory tracking and headcount of target personnel within the office scene area.

[0048] No risk of privacy leakage: Compared with cameras, millimeter-wave radar does not involve privacy leakage and complies with relevant privacy regulations. It is more suitable for office scenarios where it is not convenient to deploy cameras, such as employee office areas, meeting spaces, open spaces, and even highly sensitive places such as toilets and rest areas.

[0049] Strong environmental adaptability: Compared with infrared sensing equipment that relies on translucent materials such as glass and plastic as the outer shell, ultrasonic equipment needs to avoid the shortcomings of obstructions when in use, while millimeter-wave radar has fewer limiting factors. It does not need to have a specific shape setting like infrared sensors, nor does it need to be installed in a place with a wide viewing angle like a smart camera. It has penetrating characteristics and can be integrated into different devices to function as a basic hardware.

[0050] In response to the technical problem in the related art that the angle of the air guide plate is adjusted too frequently, affecting the service life of the stepper motor, the embodiment of the present application conceives that the number of times the angle of the air guide plate is adjusted can be reduced, which not only reduces the heat generated by the stepper motor but also increases the service life of the stepper motor.

[0051] The adaptive air supply method provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0052] like Figure 2 As shown, an adaptive air supply method provided in an embodiment of the present application may include the following steps 201 to 203:

[0053] Step 201: Acquire in real time the sub-area where the target object is located in the air supply area of ​​the air conditioner through the millimeter wave radar.

[0054] The target object is any one of at least one object in the air supply area; the air supply area is evenly divided into a plurality of sub-areas according to the air supply angle, and the air supply angle corresponding to each sub-area is the same.

[0055] Exemplarily, the above-mentioned millimeter-wave radar is a millimeter-wave radar installed on the indoor unit of the air conditioner. The millimeter-wave radar can locate objects in the scanning area and determine the relative position information between the millimeter-wave radar and any target object.

[0056] For example, Figure 3 As shown in (A), the millimeter wave radar can be set on the side of the air outlet of the indoor unit of the air conditioner to measure the position of the user in the scanning area so as to determine the area where the user is located.

[0057] It is understandable that when the air conditioner is in operation, its air supply range is usually small due to the limitation of the air outlet size, but the air conditioner can supply air to different areas by adjusting the angle of the air guide plate to expand the air supply range. The area where the air conditioner can supply air is the air supply area of ​​the air conditioner, which is usually a 150° fan-shaped area. Based on the fan-shaped area, the area can be divided into 30° intervals, that is, each 30° fan-shaped area is divided into a sub-area.

[0058] Step 202: When the sub-region where the target object is located changes, determine the number of sub-regions spanned by the target object.

[0059] For example, to avoid the slight movement of the target object triggering the angle adjustment of the air guide plate of the air conditioner, the angle of the air guide plate can be adjusted when the target object changes its area. At the same time, to avoid too frequent angle adjustments, the angle of the air guide plate can be adjusted after the target object has completed its movement.

[0060] For example, Figure 3 As shown in (B), the air supply area of ​​the air conditioner can be evenly divided into multiple sub-areas according to the angle, and the millimeter wave radar can be used to monitor the user's regional changes so that the air conditioner can adjust the angle of the air guide plate in time according to the user's regional changes.

[0061] Specifically, the above step 202 may further include the following steps 202a1 to 202a3:

[0062] Step 202a1: When the target object is detected to be moving, start recording the moving angle of the target object.

[0063] Step 202a2: When the target object stops moving, stop recording the moving angle of the target object, and determine the target moving angle of the target object during the movement.

[0064] Step 202a3: Determine the number of sub-areas that the target object moves across based on the target movement angle, the sub-area where the target object was located before the movement, and the air supply angle of each sub-area.

[0065] For example, taking the air supply angle corresponding to each sub-area as 30°, when the moving angle of the target object is 90°, it can be determined that the number of sub-areas spanned by the target object is 3.

[0066] It should be noted that in the embodiment of the present application, when most of the target object (for example, 70%) is located in a sub-area, the target object can be considered to be in the sub-area. Specifically, the air supply scheme can be centered on the sub-area and supply air to the sub-area and two sub-areas adjacent to the sub-area.

[0067] Step 203: determine a target adjustment angle of the air guide plate of the air conditioner according to the moving direction of the target object and the number of sub-areas spanned by the target object, and control the air guide plate to adjust its angle according to the target adjustment angle.

[0068] For example, when the target object changes its area, the adjustment angle of the wind deflector can be determined according to the moving direction of the target object and the number of sub-areas that the target object crosses. The moving direction of the target object can determine the positive and negative values ​​of the adjustment angle of the wind deflector, and the number of sub-areas that the target object crosses can determine the angle value of the adjustment angle of the wind deflector.

[0069] Exemplarily, after the angle of the air guide plate is adjusted based on the target adjustment angle, air can continue to be supplied to the sub-area where the target object is located, and at the same time, the heat generated by the stepper motor can be reduced.

[0070] In a possible implementation, if there are multiple users in the air supply area and the air supply range cannot cover all users, the air conditioner can be controlled to sweep the air so that each user can be blown by the wind.

[0071] Exemplarily, after the above step 201, the adaptive air supply method provided in the embodiment of the present application may further include the following steps 204 to 206:

[0072] Step 204: when the air supply area contains a plurality of objects, obtain a target area where the plurality of objects are located in the air supply area; the target area includes a plurality of sub-areas.

[0073] Step 205: Determine the area coverage of the target area according to the distribution of each sub-area in the target area within the air supply area.

[0074] Step 206: When the area coverage is larger than the maximum air supply range of the air conditioner, the target area is determined as the air sweeping area of ​​the air conditioner, and the air sweeping of the air conditioner is controlled so that the air conditioner can circulate and supply air to each sub-area of ​​the target area.

[0075] Specifically, when any of the multiple objects changes its area, thereby expanding the scope of the target area, the wind sweeping area can be re-determined according to the method in the above steps, and the wind sweeping angle of the air conditioner can be adaptively adjusted.

[0076] Optionally, in an embodiment of the present application, the air supply area of ​​the air conditioner can be divided into zones by the following steps.

[0077] Exemplarily, before the above step 201, the adaptive air supply method provided in the embodiment of the present application may further include the following steps 207 and 208:

[0078] Step 207: Determine the number of sub-areas and the air supply angle of each sub-area according to the ratio of the air supply angle corresponding to the air supply area to the preset division angle.

[0079] Step 208: Divide the air supply area into multiple sub-areas according to the number of sub-areas and the air supply angle of each sub-area.

[0080] For example, if the air supply area is a 150° fan-shaped area, if you want to divide the air sweeping area into 5 sub-areas, you can divide the air supply area into 30° fan-shaped areas for each sub-area. The number of sub-areas is positively correlated with the number of times the air guide plate angle is adjusted, that is, the more sub-areas there are, the more times the air guide plate angle is adjusted.

[0081] Optionally, in an embodiment of the present application, since the user position obtained by the millimeter-wave radar is the position of the user relative to the millimeter-wave radar, in order to accurately determine the sub-area where the user is located, it is also necessary to convert the user position information obtained by the millimeter-wave radar into the relative position information of the user relative to the air supply area of ​​the air conditioner.

[0082] Specifically, the above step 201 may include the following steps 201a and 201b:

[0083] Step 201a: obtaining relative position information between the target object in the air supply area and the air supply area through the millimeter wave radar.

[0084] Step 201b: determine the sub-area where the target object is located according to the relative position information between the target object and the air supply area.

[0085] Specifically, the above step 201a may include the following steps 201a1 to 201a3:

[0086] Step 201a1, obtaining a first distance between the midline of the scanning area of ​​the millimeter wave radar and the midline of the air supply area of ​​the air supply area.

[0087] Step 201a2: Acquire, through the millimeter-wave radar, the relative position information between the target object and the millimeter-wave radar, and the second distance between the target object and the center line of the scanning area.

[0088] Step 201a3: Calculate a third distance between the target object and the centerline of the air supply area according to the first distance and the second distance, and convert the relative position information between the target object and the millimeter-wave radar into the relative position information between the target object and the air supply area based on the third distance.

[0089] For example, Figure 4 As shown, in order to convert the relative position information between the target object and the millimeter-wave radar into the relative position information between the target object and the air supply area of ​​the air conditioner, it is first necessary to calculate the distance D between the midpoint of the scanning area of ​​the scanning area of ​​the millimeter-wave radar and the midpoint of the air supply area of ​​the air supply area of ​​the air conditioner (i.e., the above-mentioned first distance, which can be obtained through the configuration information of the air conditioner, or stored in the air conditioner in the factory setting), and then calculate the distance between the target object and the midpoint of the air supply area (i.e., the above-mentioned third distance) according to the distance between the target object and the midpoint of the scanning area (i.e., the above-mentioned second distance). Finally, the relative position information between the target object and the air supply area can be obtained based on the third distance and the relative position information between the target object and the millimeter-wave radar, so as to accurately determine the sub-area where the target object is located. The relative position information between the above-mentioned target object and the millimeter-wave radar is mainly used to determine the distance between the target object and the millimeter-wave radar, so as to further determine the distance between the target object and the air conditioner.

[0090] Specifically, the above step 201b may include the following steps 201b1 and 201b2:

[0091] Step 201b1: Calculate the angle between the target object and the midline of the air supply area according to the relative position information between the target object and the air supply area.

[0092] The angle between the target object and the midline of the air supply area is obtained based on the intersection of the boundary line of each sub-area and the midline of the air supply area.

[0093] For example, Figure 5As shown, the intersection of the boundary line of each sub-area and the midline of the air supply area is point O, and the angle formed by the line connecting the user and point O and the midline of the air supply area is the angle between the target object and the midline of the air supply area. The air supply angle corresponding to each sub-area is also calculated based on the intersection of the boundary line of the sub-area and the midline of the air supply area. This area division method can ensure that the size of each sub-area remains consistent.

[0094] Step 201b2: Determine the sub-area where the target object is located according to the angle between the target object and the midline of the air supply area and the air supply angle of each sub-area.

[0095] For example, after obtaining the relative position information of the target object and the air supply area, the angle between the target object and the midline of the air supply area can be further calculated. Based on the angle between the target object and the midline of the air supply area and the air supply angle of each sub-area, the sub-area where the target object is located can be calculated.

[0096] For example, after determining the sub-area where the target object is located, it is possible to more accurately determine whether the target object has changed its area when the target object moves, so that the air conditioner can adjust the angle of the air guide plate in a timely and accurate manner.

[0097] The adaptive air supply method provided in the embodiment of the present application first obtains the sub-area where the target object is located in the air supply area of ​​the air conditioner in real time through the millimeter wave radar; then, when the sub-area where the target object is located changes, the number of sub-areas crossed by the target object is determined; finally, according to the moving direction of the target object and the number of sub-areas crossed by the target object, the target adjustment angle of the air guide plate of the air conditioner is determined, and the air guide plate is controlled to adjust the angle according to the target adjustment angle; wherein the target object is any one of at least one object in the air supply area; the air supply area is evenly divided into multiple sub-areas according to the air supply angle, and the air supply angle corresponding to each sub-area is the same. In this way, by reducing the number of adjustments to the angle of the air guide plate, not only the heat generated by the stepper motor can be reduced, but also the service life of the stepper motor can be increased.
