[0036] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme of the present application will be described clearly and completely below in conjunction with the drawings in the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0037] The terms "first", "second" and the like 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 interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second" and the like are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in a "or" relationship.

[0038] The operation principle of the air conditioner related to the embodiments of the present application is described in detail as follows:

[0039] As shown in Figure 1 , the compressor compresses the refrigerant (cooling medium) and delivers it to the condenser through the pipeline. The high-temperature and high-pressure gaseous refrigerant releases heat in the condenser and becomes a medium-temperature and high-pressure liquid refrigerant. Then, the medium-temperature and high-pressure liquid refrigerant is depressurized by the capillary tube (throttling unit) and becomes a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant is delivered to the evaporator and evaporated into a 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 delivered to the compressor and participates 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.

[0040] The following describes the professional terms related to the embodiments of the present application:

[0041] Millimeter wave radar: a new type of wireless communication technology that has developed rapidly in recent years, and has a wide range of applications in human body detection. Millimeter wave radar technology is to emit millimeter wave signals to the target object and receive its echo signals, and use the slight changes of the weak signals to extract the relevant information of the target object, to realize non-contact and non-invasive measurement and identification of the object.

[0042] Based on the above characteristics of millimeter wave radar, its application in human body detection includes the following aspects:

[0043] Health monitoring: By detecting physiological parameters such as heart rate, respiration, body temperature, etc., it can be used for health monitoring and disease prevention. For example, in the medical field, millimeter wave radar can be used to monitor the heart or respiratory power of patients, which can allow doctors to more accurately understand the health status of patients.

[0044] Gesture recognition: By detecting and recognizing human gestures, it can be further applied to human motion analysis, body position correction, etc., which can greatly help people's physical health and exercise effect. For example, in the gym, millimeter wave radar can be used to detect whether the athlete's posture is accurate, so as to correct the athlete's wrong posture and reduce the damage of exercise.

[0045] Human safety detection: Millimeter wave radar can conduct security checks on the human body, identify and detect dangerous goods and thermal energy substances, etc., such as timely detection of personnel carrying dangerous goods in airports and large public places, etc., to ensure safety. In addition, when the human body condition is not good, the millimeter wave radar can also automatically send signals to emergency personnel to obtain emergency help.

[0046] In summary, millimeter wave radar has many applications in human body detection, which can effectively improve people's quality of life and ensure the safety of the human body. With the development of millimeter wave radar technology, future applications will be more extensive and diverse.

[0047] Compared with traditional infrared sensors, millimeter wave radar has the following advantages:

[0048] Low false touch, wide range: Compared with infrared sensor triggering, it reduces the false touch rate and breaks through the limitations of mobile monitoring. Millimeter wave radar can realize target personnel presence perception, trajectory tracking, and number statistics in the office scene area.

[0049] No privacy leakage risk: Compared with cameras, millimeter wave radar does not involve privacy leakage and meets relevant privacy regulations. It is more suitable for office scenarios where cameras are not convenient to deploy, such as employee office areas, conference spaces, open spaces, and even highly sensitive places such as restrooms and rest areas.

[0050] Strong environmental adaptability: Compared with infrared sensor devices that rely on glass, plastic, and other light-transmitting materials as the shell, and ultrasonic devices that need to avoid obstructions during use, millimeter wave radar has fewer limitations. It does not have to have a specific shape like an infrared sensor, nor does it have to be installed in a wide-angle view like a smart camera. With its penetrating characteristics, it can be integrated into different devices as a basic hardware to function.

[0051] Swimmers often experience a cooling sensation when entering and exiting the water. While some technologies address this by using air conditioning to increase the indoor temperature, this method does not completely eliminate the initial cooling sensation upon entering the water.

[0052] In view of the above-mentioned technical problems in related technologies, this application provides an air conditioner control method for swimming pool scenarios. This control method can reduce the cold feeling when swimmers enter the water and reduce the cold feeling when swimmers exit the water.

[0053] The air conditioner control method for swimming pool scenarios provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0054] like Figure 2 As shown in the embodiment of this application, an air conditioner control method for a swimming pool scenario is provided. This method may include any one of the following steps 201, 202, and 203:

[0055] Step 201: Monitor the swimming status of the target object using the millimeter-wave radar installed on the air conditioner to obtain the swimming status information of the target object.

[0056] For example, the millimeter-wave radar mentioned above can be a millimeter-wave radar installed on an air conditioner, or it can be a millimeter-wave radar installed separately in the swimming venue, but it can interact with the air conditioner. The target object mentioned above is any swimmer in the swimming venue.

[0057] It should be noted that, to protect user privacy, cameras are not suitable for target tracking and monitoring inside swimming venues. Furthermore, images captured by cameras are insufficient to calculate human height, making it impossible to obtain the aforementioned target information. This embodiment employs millimeter-wave radar for target tracking and monitoring, which not only avoids the leakage of user privacy but also measures the human posture information of any target object and further determines the target object's swimming status.

[0058] Step 202: If the swimming status information indicates that the target object is about to enter the water, perform the first target operation.

[0059] The first target operation is used to reduce the cooling sensation of the target object when it enters the water.

[0060] Exemplarily, when the air conditioner determines that the target object will enter the water through the millimeter wave radar, the air conditioner will control the air conditioner to perform a first target operation before the target object enters the water, the first target operation being used to lower the body surface temperature of the target object, so that the target object can adapt to the lower water temperature in advance, and avoid the cold feeling caused by the large temperature difference when entering the water.

[0061] Step 203, in the case where the swimming state information indicates that the swimming state of the target object is about to exit the water, a second target operation is performed.

[0062] The second target operation is used to reduce the cold feeling of the target object when exiting the water.

[0063] Exemplarily, when the air conditioner determines that the target object will enter and exit through the millimeter wave radar, the air conditioner will control the air conditioner to perform a second target operation during the process of the target object exiting the water, the second target operation being used to evaporate the water on the surface of the body of the target object in advance, so as to avoid the cold feeling caused by the rapid evaporation of the water on the surface of the body of the target object due to air flow when the target object exits the water.

[0064] Optionally, in the embodiment of the present application, the tracking and identification of any target object in the swimming venue can be realized through the following steps.

[0065] The above step 201 can include the following steps 201a and 201b.

[0066] Step 201a, acquiring a target radar image containing the target object collected by the millimeter wave radar at the current time, and determining the current human body feature of the target object according to the target radar image.

[0067] Step 201b, in the case where it is determined that the target object is located in the pool area, determining the swimming state information according to the current human body feature and the historical human body feature of the target object.

[0068] The historical human body feature is obtained based on the radar image containing the target object collected by the millimeter wave radar before the current time.

[0069] Exemplarily, the above-mentioned human body features can include human body posture features, human body appearance features, etc., based on which the body height of the human body, the inclination angle of the human body, and other information can be determined.

[0070] Exemplarily, the above-mentioned target radar image is used to determine the current human body feature of the target object, based on which the current body length of the target object can be determined.

[0071] It should be noted that since the ultrasonic signal emitted by the millimeter wave radar cannot penetrate the water body, the millimeter wave radar can only identify the human body features of the target object on the water surface and determine the body length of the target object on the water surface based on the human body features.

[0072] Illustratively, the historical radar image is used to determine the historical human body features of the target object, and based on the historical human body features, the overall body length of the target object, i.e., the height of the target object, can be determined.

[0073] Illustratively, based on the current body length and the height of the target object, the swimming state of the target object can be determined, and thus the swimming state information is obtained.

[0074] Optionally, in the embodiments of the present application, the tracking and matching of each swimmer in the swimming place can be achieved by the following steps.

[0075] Illustratively, before the step 201a, the air conditioner control method for a swimming pool scene provided by the embodiments of the present application can further include the following steps 204 and 205, and any one of steps 206 and 207:

[0076] Step 204, obtaining a to-be-matched radar image containing a to-be-matched object collected by the millimeter wave radar.

[0077] Step 205, determining a first human body feature of the to-be-matched object according to the to-be-matched radar image, and matching the first human body feature with the human body features in the human body feature library.

[0078] Step 206, in the case that there is a second human body feature in the human body feature library that matches the first human body feature, associating the to-be-matched radar image with at least one historical radar image, and determining that the to-be-matched object is the target object.

[0079] Step 207, in the case that there is no human body feature in the human body feature library that matches the first human body feature, adding the first human body feature to the human body feature library, and establishing an association relationship among the target radar image, the first human body feature, and the target object.

[0080] Wherein, the at least one historical radar image is a radar image associated with the second human body feature; and the second human body feature is a human body feature associated with the target object.

[0081] It can be understood that, as Figure 3As shown, after the radar image is acquired, each object contained in the radar image needs to be tracked and matched, that is, after the human body features of each object are acquired, the human body features in the human body feature library are matched, and if the matching is successful, it indicates that the object has been marked. At this time, the maximum body length of the object, that is, the body height of the object, can be determined according to the historical radar image associated with the object in the radar image library. If the matching fails, it indicates that the object is a new swimmer entering the swimming pool. At this time, the human body features of the object can be recorded in the human body feature library, and the radar image of the object can be stored in the radar image library, and the association between the radar image and the object is established.

[0082] Based on this, the human body features of each swimmer in the swimming pool can be matched according to the association between the object, the human body features and the radar image, and then the target information of each swimmer can be obtained.

[0083] In a possible implementation, if no human body feature matching the target object is detected for more than a preset time length, it indicates that the target object may have left the swimming place, that is, in the case that the target object is not detected for a long time, it is judged that the target object has left. At this time, the human body feature data of the target object can be deleted from the human body feature library to reduce the amount of calculation.

[0084] It should be noted that the body height of the target object recorded in the above steps can be multiple values, that is, the body height in different states (including standing, bending and squatting). When calculating the length of the body below the water surface, the maximum value of the body height can be selected as the maximum body length of the target object.

[0085] Specifically, after the step 207, the air conditioner control method for a swimming pool scene provided by the embodiment of the present application can further include the following step 208.

[0086] Step 208: In the case that no human body feature matching the target object is detected for more than a preset time length, the human body feature of the target object is deleted from the human body feature library.

[0087] Optionally, in the embodiment of the present application, the swimming state of the target object can be determined by the following method.

[0088] Specifically, the swimming pool area includes a swimming area and a non-swimming area, and the step 201b can include the following step 201b1 or step 201b2.

[0089] Step 201b1: In the case that the target object is determined to be close to the swimming area based on the current human body feature and the historical human body feature, the swimming state of the target object is determined to be a state of about to enter the water.

[0090] Step 201b2, in a case where it is determined based on the current human feature and the historical human feature that the target corresponds to being close to a non-swimming area and the length of the part of the target object exposed out of the water gradually increases, determining that the swimming state of the target object is a state of about to get out of the water.

[0091] It should be noted that the millimeter wave radar can monitor the action and posture of the target object, and based on the action and posture of the target object, a series of behaviors of the target object can be judged, and it can be further judged whether the target object is about to swim into the water or get out of the water.

[0092] Further, in the embodiments of the present application, the cool feeling of the target object when getting into the water and getting out of the water can be reduced by the following steps.

[0093] Specifically, the above-mentioned step 202 can include the following step 202a:

[0094] Step 202a, controlling the air conditioner to run in a cooling mode and controlling the air conditioner to blow air to a target area where the target object is located, so as to reduce the body surface temperature of the target object.

[0095] Exemplarily, as shown in the air conditioner Figure 4 After the millimeter wave radar captures the human target, the air conditioner records the height H of the target, that is, the maximum body length. Then, the air conditioner determines the swimming state of the target object according to the radar image generated by the millimeter wave radar. When the swimming state of the target object is about to get into the water, the air conditioner can enter the cooling mode, and the air follows the person to reduce the body surface temperature of the person and reduce the temperature difference with the water temperature in the pool, so as to ensure that there is no cool feeling when getting into the water.

[0096] Specifically, the above-mentioned step 203 can include the following step 203a1 and step 203a2:

[0097] Step 203a1, determining the maximum body length of the target object according to the historical human feature, and determining the first body length of the part of the target object exposed out of the water according to the current human feature.

[0098] Step 203a2, calculating a target ratio of the first body length to the maximum body length.

[0099] Specifically, after the above-mentioned step 203a2, the above-mentioned step 203 can further include any one of the following steps 203b1 to 203b3:

[0100] Step 203b1, in a case where the target ratio is less than a first preset threshold, controlling the air conditioner to run in a dehumidification mode and controlling the air conditioner to blow air to an area other than the target area where the target object is located.

[0101] Step 203b2: When the target ratio is greater than or equal to the first preset threshold and less than the second preset threshold, control the air conditioner to operate in heating mode and control the air conditioner to adjust the air supply mode to automatic air supply.

[0102] Step 203b3: If the target ratio is greater than or equal to the second preset threshold, control the air conditioner to operate in heating mode and control the air conditioner to deliver air to the target area.

[0103] Wherein, the first preset threshold is less than the second preset threshold.

[0104] For example, such as Figure 4 As shown, when the target swimmer is about to emerge from the water, the first step is to calculate the proportion of the target swimmer's body above water, Q = h / H, where h is the length of the target swimmer's body above the water surface. Then, the value of Q is determined. When Q < 30% (i.e., the first preset threshold mentioned above), the air conditioner is controlled to enter dehumidification mode, and the airflow avoids the target swimmer. When 30% ≤ Q < 60% (i.e., the second preset threshold mentioned above), the air conditioner is controlled to enter heating mode, and automatic fan control is set. When Q ≥ 60% (i.e., the second preset threshold mentioned above), the air conditioner is controlled to enter heating mode, and the fan moves with the swimmer. This allows for the pre-evaporation of moisture from the target swimmer's body surface, preventing the swimmer from feeling cold due to air convection within the venue after emerging from the water.

[0105] It should be noted that the above-mentioned control of the air conditioner to enter dehumidification mode is used to reduce the ambient humidity in order to accelerate the evaporation of moisture on the surface of the target's body. Similarly, controlling the air conditioner to enter heating mode and blowing air into the area where the target is located is used to accelerate the evaporation of moisture on the target's body surface while keeping the target warm and preventing the target from feeling cold due to heat absorption during evaporation.

[0106] The air conditioner control method for swimming pool scenarios provided in this application first monitors the swimming state of a target object using a millimeter-wave radar installed on the air conditioner to obtain swimming state information of the target object. Then, if the swimming state information indicates that the target object is about to enter the water, a first target operation is executed; or, if the swimming state information indicates that the target object is about to exit the water, a second target operation is executed. The first target operation reduces the cooling sensation when the target object enters the water; the second target operation reduces the cooling sensation when the target object exits the water. Thus, by adjusting the air conditioner according to the target object's swimming state, the problem of swimmers feeling cold upon entering and exiting the water can be solved, improving the swimmer's swimming experience.
