[0002] As people's living standards improve, more and more people go to gyms or professional swimming pools to swim or take professional swimming training. In order to ensure that swimmers can have a comfortable swimming environment, a water circulation system is usually installed in the swimming pool to heat and keep the water in the swimming pool warm.

[0003] In the related art, a swimming pool water circulation inlet and outlet are usually set on the swimming pool wall, the water in the swimming pool is pumped out, heated and filtered, and then the heated and filtered water is sent back to the swimming pool. However, since the inlet and outlet of such a water circulation system are set on the swimming pool wall, the water flow it sprays will affect the calmness of the water surface and even cause turbulence in the upper layer of the pool, which can easily cause interference to swimmers.

[0038] 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.

[0039] 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.

[0040] The operating principle of the air conditioner involved in the embodiment of the present application is described in detail below:

[0041] like Figure 1 As 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.

[0042] According to the operating principle of the above-mentioned air stripper, the refrigerant output by the compressor will release a large amount of heat, based on which the heat can be used to heat the water in the swimming pool.

[0043] The following is a description of the professional terms involved in the embodiments of the present application:

[0044] 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.

[0045] Based on the above characteristics of millimeter wave radar, its application in human body detection includes the following aspects:

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] Compared with traditional infrared sensors, millimeter wave radar has the following advantages:

[0051] 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.

[0052] 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.

[0053] 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.

[0054] The water circulation system of the swimming pool in the related art may interfere with the swimmers. Figure 2 As shown, the embodiment of the present application provides a swimming pool heating system, such as Figure 2 As shown in (A), the swimming pool heating system includes: a circulation pipeline and a heat accumulator; the heat accumulator uses the heat generated by the heat exchanger of the air conditioner to heat the low-temperature water into high-temperature water; Figure 2 As shown in (B), the circulation pipeline is used to send the low-temperature water in the swimming pool into the heat accumulator for heating, and the heated high-temperature water is transported to the swimming pool through the circulating water pump arranged at the bottom of the swimming pool. At the same time, a filtering device can also be arranged in the heat accumulator to filter impurities in the water.

[0055] It should be noted that the above-mentioned swimming pool heating system may further include a controller, and the execution subject of the control method of the swimming pool heating system provided in the embodiment of the present application may be the controller; the controller may be a control unit of an air conditioner or an independent electronic device.

[0056] The control method of the swimming pool heating system 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.

[0057] based on Figure 2 ,like Figure 3 As shown, an embodiment of the present application provides a method for controlling a swimming pool heating system, which may include the following steps 301 and 302:

[0058] Step 301: Monitor the human body features of a target object in a swimming pool based on a millimeter wave radar to obtain target information.

[0059] The target information is higher than the body length indicating that the target object is below the water surface.

[0060] Exemplarily, the millimeter-wave radar may be disposed on an indoor unit of an air conditioner, or may be disposed in other areas within the venue where the swimming pool is located. The millimeter-wave radar may be one or more.

[0061] It should be noted that, in order to protect the privacy of users, it is not suitable to use cameras for target tracking and monitoring inside swimming places, and it is difficult to calculate the height of the human body through the images collected by the camera, so that the above target information cannot be obtained. In the embodiment of the present application, the millimeter wave radar is used to track and monitor the target, which can not only avoid the leakage of user privacy, but also accurately calculate the height of the human body, and then calculate the body length of the target object under the water, that is, the above target information.

[0062] Exemplarily, the above-mentioned human body characteristics may include: human body posture characteristics, human body appearance characteristics, etc. Based on the human body characteristics, information such as the body height and the tilt angle of the human body may be determined.

[0063] Step 302: determine a target operating power of a target circulating water pump according to the target information, and control the operation of the circulating water pump according to the target operating power so that the height of the water flow sprayed by the target circulating water pump is less than the target distance between the lowest point of the target object's body and the bottom of the swimming pool.

[0064] Wherein, a plurality of circulating water pumps are arranged at the bottom of the swimming pool, and the target circulating water pump is a circulating water pump located below the position where the target object is located among the plurality of circulating water pumps.

[0065] For example, after obtaining the target information of the target object, the target operating power of the target circulating water pump located below the target object can be determined based on the target information. The target circulating water pump is controlled to operate according to the target operating power, so that the height of the water flow sprayed below the target object is less than the target distance between the lowest point of the target object's body and the bottom of the swimming pool. That is, the water flow sprayed by the target circulating water pump is always below the target object's body and will not touch the target object's body, so as to avoid interference with the target object.

[0066] Optionally, in an embodiment of the present application, the body length of the target object under the water surface may be obtained through the following steps.

[0067] Specifically, the above step 301 may include the following steps 301a and 301b:

[0068] Step 301a: obtain a target radar image containing the target object collected by the millimeter-wave radar at the current moment, and determine the target human body features of the target object according to the target radar image.

[0069] Step 301b: When it is determined that the target object is located in the swimming pool area, the target information is determined according to the target human body characteristics and historical human body characteristics of the target object.

[0070] The historical human features are obtained based on radar images containing the target object collected by the millimeter-wave radar before the current moment.

[0071] Exemplarily, the target radar image is used to determine the target human body features of the target object, and based on the target human body features, the body length of the target object above the water surface can be determined.

[0072] Exemplarily, the above historical radar images are used to determine the historical human features of the target object, and based on the historical human features, the total body length of the target object, that is, the height of the target object, can be determined.

[0073] Exemplarily, based on the length of the target object's body above the water surface and the target object's height, the length of the target object's body below the water surface, ie, the above-mentioned target information, can be calculated.

[0074] Furthermore, the above step 301a may further include the following steps 301a1 and 301a2:

[0075] Step 301a1: determine the maximum body length of the target object according to the historical body characteristics, and determine the first body length of the target object's portion exposed above the water surface according to the target body characteristics.

[0076] Step 301a2: Determine a second body length of the target object under the water surface according to the difference between the maximum body length and the first body length.

[0077] For example, after obtaining the maximum body length of the target object and the first body length of the target object above the water surface, the second body length of the target object below the water surface, that is, the above-mentioned target information, can be calculated.

[0078] Specifically, based on the above step 301a2, the step of determining the target operating power of the target circulating water pump according to the target information in the above step 302 may include the following steps 302a1 and 302a2:

[0079] Step 302a1, determining the body inclination angle of the target object according to the target human body features, and calculating the target distance according to the body inclination angle, the second body length and the water depth of the swimming pool.

[0080] Step 302a2: Determine the target operating power of the target circulating water pump according to the target distance, the maximum operating power of the target circulating water pump, and the maximum water jet height of the target circulating water pump.

[0081] Exemplarily, the water depth of the swimming pool may be the vertical distance from the free section of the water body to the bottom of the swimming pool.

[0082] For example, since the body tilt will reduce the distance between the lowest part of the target object's body and the bottom of the swimming pool, the body tilt angle of the target object also needs to be considered when calculating the above target distance. The body tilt angle of the target object can be detected by millimeter wave radar.

[0083] Specifically, the above step 302a2 may include the following steps 302a21:

[0084] Step 302a21, calculating a target ratio of the target distance and the swimming pool water depth, and determining the target operating power as the product of the target ratio and the maximum operating power of the target circulating water pump.

[0085] Exemplarily, the above maximum operating power can be determined according to the maximum water jet height of the target circulating water pump, and the maximum water jet height of the target circulating water pump is the water depth of the swimming pool. That is, the maximum water jet height of the target circulating water pump will not exceed the water depth of the swimming pool. The maximum operating power of the target circulating water pump can be limited according to the water depth of the swimming pool.

[0086] Exemplarily, the target operating power W of the target circulating water pump can be calculated by the following formula 1:

[0087]

[0088] Among them, H is the body height of the target object, h is the body length of the target object above the water surface, θ is the body inclination angle of the target object, and P is the maximum operating power of the target circulating water pump.

[0089] In a possible implementation, the target circulating water pump to be controlled may be determined through the following steps.

[0090] For example, before the above step 302, the control method of the swimming pool heating system provided in the embodiment of the present application may further include the following steps 303 and 304:

[0091] Step 303: Divide the swimming pool area into multiple sub-areas according to the position information of each circulating water cup in the multiple circulating water pumps.

[0092] Among them, one circulating water pump corresponds to one sub-area.

[0093] Step 304: determine the target sub-region where the target object is located according to the radar image collected by the millimeter-wave radar, and determine the circulating water pump corresponding to the target sub-region as the target circulating water pump.

[0094] For example, Figure 2 As shown, the swimming pool area can be divided into multiple sub-areas according to the installation position of each circulating water pump, and each sub-area corresponds to a circulating water pump. After the target object is located by millimeter-wave radar, it can be determined in which sub-area it is located, and then the circulating water pump corresponding to the sub-area is controlled so that the water flow ejected by the circulating water pump in the sub-area does not interfere with the target object's swimming.

[0095] It should be noted that the embodiment of the present application includes steps of monitoring any target object and controlling the target circulating water pump corresponding to the target sub-area where the target object is located. In actual applications, multiple objects can be monitored and controlled at the same time, and the trajectory of the target object can be tracked so that the circulating water pump corresponding to the sub-area can be controlled in advance before the target object enters the next sub-area.

[0096] Optionally, in an embodiment of the present application, tracking and matching of each swimmer in a swimming venue may be achieved through the following steps.

[0097] For example, before the above step 301a, the control method of the swimming pool heating system provided in the embodiment of the present application may further include the following steps 305 and 306, and any one of steps 307 and 308:

[0098] Step 305: Acquire a radar image to be matched that is collected by the millimeter-wave radar and contains an object to be matched.

[0099] Step 306: Determine a first human feature of the object to be matched according to the radar image to be matched, and match the first human feature with human features in a human feature library.

[0100] Step 307: When there is a second human feature matching the first human feature in the human feature library, the radar image to be matched is associated with at least one historical radar image, and the object to be matched is determined to be the target object.

[0101] Step 308: If there is no human feature matching the first human feature in the human feature library, add the first human feature to the human feature library, and establish an association relationship between the target radar image, the first human feature and the target object.

[0102] The at least one historical radar image is a radar image associated with the second human feature; and the second human feature is a human feature associated with the target object.

[0103] It is understandable that if Figure 4As shown in the figure, after the radar image is acquired, each object contained in the radar image needs to be tracked and matched, that is, after acquiring the human features of each object, they are matched with the human features in the human feature library. If the match is successful, it means 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 based on the historical radar images associated with the object in the radar image library. If the match fails, it means that the object is a new swimmer. At this time, the human features of the object can be recorded in the human feature library, and the radar image of the object can be stored in the radar image library, and the association relationship between the radar image and the object can be established.

[0104] Based on this, the human features of each swimmer in the swimming pool can be matched according to the association between objects, human features and radar images, and then the target information of each swimmer can be obtained.

[0105] In one possible implementation, if no human features matching the target object are detected for more than a preset time, it means that the target object may have left the swimming place. That is, if the target object is not detected for a long time, it is judged that it has left. At this time, the human feature data of the target object can be deleted from the human feature library to reduce the amount of calculation.

[0106] For example, Figure 5 As shown, it is a complete flow chart of the control method of the swimming pool heating system provided in the embodiment of the present application. First, the millimeter-wave radar captures the human target and determines whether the target is located in the swimming pool area. If not, the human height H of the target is recorded; if so, the height h above the water surface is further detected by the millimeter-wave radar. After that, the inclination angle θ of the target's body and the length Hh of the human body below the water surface are calculated. Finally, the distance Q = (Hh) * sinaθ from the lowest point of the human body to the bottom of the swimming pool is calculated, and the operating power W of the circulating water pump under the human body is calculated: W = Q * P / S, P is the maximum power of the circulating water pump.

[0107] It should be noted that the human body height H of the target recorded in the above steps can be multiple values, that is, the human body height in different states (including: standing, bending over, squatting). When calculating the length of the human body below the water surface, a maximum value of the human body height H can be selected for calculation.
