Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and in particular to an air conditioning system and a control method based on swimming pool safety early warning. Background Art

[0002] As people's living standards continue to improve, they have higher requirements for the environment of leisure places such as swimming pools. Therefore, swimming pools need to install heat pumps and air conditioners to adjust the temperature of the pool and the room. Because the pool is large, human sensing devices are usually installed to monitor the use of the pool. However, the human sensing device will misjudge the absence of people on the water surface as diving due to water interference, ignoring the drowning situation in the pool. Therefore, the existing air conditioners dedicated to swimming pools have poor control accuracy in safety warning. Summary of the invention

[0003] The present invention provides an air conditioning system and a control method based on swimming pool safety warning, which are used to solve the defect of poor control accuracy of swimming pool-specific air conditioning in the prior art in terms of safety warning.

[0004] The present invention provides an air conditioning system based on swimming pool safety warning, comprising an air conditioning indoor unit located above the swimming pool area, and an air conditioning outdoor unit located in other spaces outside the swimming pool area;

[0005] The air-conditioning indoor unit is provided with a radar module. During the heat exchange between the air-conditioning indoor unit and the air-conditioning outdoor unit in the dehumidification mode, the air-conditioning indoor unit determines whether a drowning incident occurs in the swimming pool by using the change in the number of individuals in the swimming pool area monitored by the radar module.

[0006] According to an air conditioning system based on swimming pool safety warning provided by the present invention, the air conditioning system further comprises a swimming pool heat accumulator in the same space as the air conditioning outdoor unit;

[0007] During the heat exchange between the air-conditioning indoor unit and the air-conditioning outdoor unit in the dehumidification mode, the heat amount output by the air-conditioning outdoor unit is recovered by the heat exchanger in the swimming pool heat storage device to maintain a constant temperature of the swimming pool.

[0008] According to an air conditioning system based on swimming pool safety warning provided by the present invention, the air conditioning indoor unit performs the following steps when judging whether a drowning incident occurs in the swimming pool by using the change in the number of individuals in the swimming pool area monitored by the radar module:

[0009] The air conditioner indoor unit senses the individuals crossing the boundary of the swimming pool area through the radar module and counts the number of the first individuals;

[0010] The air conditioner indoor unit receives the second number of individuals collected by the radar module from the individuals on the water surface in the swimming pool area;

[0011] The air conditioner indoor unit determines whether a drowning incident occurs in the swimming pool according to the first number of individuals and the second number of individuals.

[0012] According to an air conditioning system based on swimming pool safety warning provided by the present invention, the air conditioning indoor unit senses individuals crossing the boundary of the swimming pool area through the radar module, and performs the following steps when the first number of individuals is counted:

[0013] The air conditioner indoor unit retrieves the number of the third individual before the current step into and / or step out of the swimming pool area boundary;

[0014] The air conditioner indoor unit obtains the number of individual changes of the swimming pool area boundary, wherein the number of individual changes includes the number of entry individuals crossing from the outside of the swimming pool area to the inside of the swimming pool area through the swimming pool area boundary, and / or the number of exit individuals crossing from the inside of the swimming pool area to the outside of the swimming pool area through the swimming pool area boundary;

[0015] The air conditioner indoor unit calculates the first individual number after entering and / or stepping out of the swimming pool area boundary this time according to the third individual number and the individual change number.

[0016] According to an air conditioning system based on swimming pool safety warning provided by the present invention, when the number of individual changes includes the number of individuals entering the swimming pool area from outside the swimming pool area to inside the swimming pool area through the swimming pool area boundary, the air conditioning indoor unit performs the following steps:

[0017] The air conditioner indoor unit receives the number of individuals entering the site sent by the radar module;

[0018] The air conditioner indoor unit accumulates the number of individuals entering the swimming pool based on the third number of individuals to obtain the first number of individuals after entering the boundary of the swimming pool area this time.

[0019] According to an air conditioning system based on swimming pool safety warning provided by the present invention, when the number of individual changes includes the number of exit individuals that cross the swimming pool area boundary from the inside of the swimming pool area to the outside of the swimming pool area, the air conditioning indoor unit performs the following steps:

[0020] The air conditioner indoor unit receives the number of individuals that have appeared sent by the radar module;

[0021] The air-conditioning indoor unit subtracts the number of entering individuals from the third number of individuals to obtain the first number of individuals after crossing the boundary of the swimming pool area this time.

[0022] According to an air conditioning system based on swimming pool safety warning provided by the present invention, the air conditioning indoor unit performs the following steps when judging whether a drowning incident occurs in the swimming pool according to the first number of individuals and the second number of individuals:

[0023] The air conditioner indoor unit determines that a drowning incident occurs in the swimming pool area when it is determined that the number of the second individuals is always less than the number of the first individuals within a first preset time period;

[0024] The air conditioner indoor unit determines that a diving event exists in the swimming pool area when it is determined that the number of the second individuals changes from being less than the number of the first individuals to being equal to the number of the first individuals within a first preset time period.

[0025] According to an air conditioning system based on swimming pool safety warning provided by the present invention, when the air conditioning indoor unit determines that the number of the second individuals is always less than the number of the first individuals within a preset time period, it determines that there is a drowning incident in the swimming pool area and then performs the following steps:

[0026] The air conditioner indoor unit sends out an alarm signal for drowning incidents in the swimming pool area;

[0027] The air conditioner indoor unit cancels the alarm signal when it is determined that the number of the second units changes from being less than the number of the first units to being equal to the number of the first units within a second preset time period.

[0028] The present invention also provides a control method for an air conditioning system based on swimming pool safety warning as described in any one of the above items, comprising:

[0029] The radar module senses the individuals that cross the border of the swimming pool area and counts the number of the first individuals;

It can accurately prevent and warn with the all-weather monitoring of the air conditioning system, prevent the occurrence of drowning incidents to the greatest extent, and effectively improve the control of the swimming pool.

[0040] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] The terms "first", "second", etc. in this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms 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 the same type, and the number of objects is not limited. For example, the first object can be one or more.

[0042] It should be understood that the terms used in the present specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the present invention, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0043] The terms “include” and “comprising” indicate the presence of described features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or combinations thereof.

[0044] Figure 1 Schematic diagram of the structure of the air conditioning system based on swimming pool safety warning provided by the present invention. Figure 1 As shown, the air conditioning system based on swimming pool safety warning provided by the embodiment of the present invention includes an air conditioning indoor unit 110 located above the swimming pool area, and an air conditioning outdoor unit 120 located in other spaces outside the swimming pool area.

[0045] The air-conditioning indoor unit 110 is provided with a radar module 111. During the heat exchange between the air-conditioning indoor unit 110 and the air-conditioning outdoor unit 120 in the dehumidification mode, the air-conditioning indoor unit 110 determines whether a drowning incident occurs in the swimming pool by using the change in the number of individuals in the swimming pool area monitored by the radar module 111.

[0046] Specifically, in the air conditioning system based on swimming pool safety warning, the air conditioner is used to adjust the temperature and humidity of the space where the swimming pool area is located, and the air conditioning indoor unit 110 in the air conditioner is set directly above the swimming pool area to adjust the temperature and humidity of the space where the swimming pool area is located through the dehumidification mode of the air conditioner.

[0047] A radar module 111 is correspondingly arranged on the air conditioner indoor unit 110. When the air conditioner indoor unit 110 is activated, the radar module 111 performs real-time calculation and analysis of electromagnetic waves reflected by individuals (i.e., target individuals) on the water surface of the swimming pool area, separates and tracks each individual detected in the swimming pool, and counts the individuals on the water surface of the swimming pool when it is confirmed that the individual crosses the edge of the swimming pool. The change in the number of individuals determined by the real-time counting reflects whether the individual has truly left the swimming pool area when the individual is not counted in the total number of groups above the swimming pool surface, or whether the individual has changed from partially exposing the body on the water surface to completely hiding the body under the water surface. In particular, in the latter case, it is necessary to further determine whether the current complete hiding of the individual's body under the water surface is due to the individual being in a diving state or a drowning incident.

[0048] It is understandable that the embodiments of the present invention do not specifically limit the type and quantity of radar sensing devices in the radar module.

[0049] Exemplarily, the radar module may include a laser radar, an infrared sensor, etc.

[0050] Optionally, since the horizontal detection range of the millimeter-wave radar can reach ±75°, the vertical detection range can reach ±40°, the maximum detection distance can reach 8 meters, the distance output accuracy can reach 0.1 meters, the angle output accuracy can reach 1°, and it does not involve privacy issues, is not affected by light, and its response speed is also faster.

[0051] Therefore, the air conditioning system collects the individual position information on the water surface of the swimming pool area in real time based on the millimeter-wave radar, tracks and summarizes the position information of each individual to analyze the changes in the number of individuals in the swimming pool.

[0052] Exemplarily, the radar module may include multiple sensor elements such as millimeter wave radar, lidar, infrared sensor, etc. The air-conditioning system integrates the individual position information collected by each sensor element, tracks and summarizes the individual position information, so as to comprehensively depict the changes in the number of individuals in the swimming pool.

[0053] In the embodiment of the present invention, the radar module installed in the indoor unit of the air conditioner observes the swimming pool from a bird's-eye view, and analyzes the changes in the number of individuals when they enter and leave the swimming pool area, which is used as a basis for judging whether a drowning incident has occurred in the swimming pool. With the all-weather monitoring of the air conditioning system, accurate prevention and early warning can be carried out to prevent the occurrence of drowning incidents to the greatest extent, effectively improving the control of the swimming pool.

[0054] Based on any of the above embodiments, the air conditioning system further includes a swimming pool heat storage device located in the same space as the air conditioning outdoor unit 120 .

[0055] During the heat exchange between the air-conditioning indoor unit 110 and the air-conditioning outdoor unit 120 in the dehumidification mode, the heat exchanger in the swimming pool heat storage device recovers the heating amount output by the air-conditioning outdoor unit 120 to maintain a constant temperature of the swimming pool.

[0056] Specifically, the air conditioner outdoor unit 120 and the swimming pool heat accumulator in the air conditioner are connected through a pipeline and are deployed together in other spaces outside the swimming pool area. A heat exchanger is housed inside the swimming pool heat accumulator, and the refrigerant input port of the heat exchanger is connected to the output end of the compressor of the air conditioner outdoor unit, while the refrigerant output port of the heat exchanger is connected to the input end of the compressor of the air conditioner outdoor unit. The swimming pool heat accumulator 130 is connected to the water outlet of the swimming pool through its own water inlet.

[0057] During the heat exchange process in any dehumidification mode of the air conditioner, after the air conditioner outdoor unit 120 compresses the low-temperature and low-pressure gas refrigerant transmitted by the air conditioner indoor unit 110 into a high-temperature and high-pressure gas refrigerant, a part of it flows to the heat exchanger deployed by the air conditioner outdoor unit 120 itself for the next dehumidification cycle, and the other part flows to the heat exchanger in the swimming pool heat accumulator, so that the heat exchanger of the swimming pool heat accumulator acts as a condenser to condense and release heat to the swimming pool water flowing through the swimming pool heat accumulator, so that the water temperature of the swimming pool area is maintained at a constant value.

[0058] The pipe structure for connecting the swimming pool heat accumulator and the swimming pool area can be designed accordingly according to the number of water pumps installed in the swimming pool. Therefore, the pipe structure can be designed as a diverter pipe system, which is composed of a converging inlet connected to the water outlet of the swimming pool heat accumulator and a diverter outlet connected to the water inlets of n water pumps in a one-to-one correspondence, so as to form n waterways between the swimming pool heat accumulator and the n water pumps. The embodiment of the present invention does not specifically limit the way in which the diverter pipe system performs zoned water supply.

[0059] For example, in the entire control process, all n water pumps can be turned on, so that the swimming pool can quickly reach a constant temperature state and maintain this state when all n water channels in the diversion pipe system are connected.

[0060] Exemplarily, in the entire control process, after turning on n water pumps to quickly reach a constant temperature value, all of them are turned off. After locating the pool partition where the human individual in the swimming pool is currently located, only the water pump corresponding to the partition is turned on to achieve the function of heat flow following the movement of the person.

[0061] The embodiment of the present invention maintains the constant temperature of the swimming pool by making the swimming pool heat accumulator recover the heating output of the air conditioner outdoor unit when running in the dehumidification mode. On the basis of using all or part of the heat energy of the air conditioner outdoor unit for the swimming pool heat accumulator to maintain the constant temperature of the swimming pool, it can also give a real-time warning of drowning events according to the change in the number of individuals in the swimming pool, thereby improving the control accuracy of the air conditioner and saving energy efficiency at a relatively small maintenance cost of the constant temperature swimming pool, and effectively improving the management and control of the swimming pool.

[0062] Based on any of the above embodiments, the air conditioner indoor unit performs the following steps when determining whether a drowning incident occurs in the swimming pool by using the change in the number of individuals in the swimming pool area monitored by the radar module:

[0063] The air conditioner indoor unit senses the individuals crossing the boundary of the swimming pool area through the radar module and counts the first number of individuals.

[0064] The air conditioner indoor unit receives the second number of individuals collected by the radar module from the individuals on the water surface in the swimming pool area.

[0065] The air conditioner indoor unit determines whether a drowning incident occurs in the swimming pool according to the first number of individuals and the second number of individuals.

[0066] Specifically, the air conditioner indoor unit performs the following steps for analysis each time after receiving the number of individuals fed back by the radar module:

[0067] First, the air conditioner indoor unit integrates the sensory information belonging to the same individual collected by the radar module, locates the body center coordinates of the individual under the current posture contour, and compares the body center coordinates of any individual with the boundary center coordinates of each boundary line of the swimming pool area. When the difference between the horizontal coordinate value and / or the vertical coordinate value of the two is greater than the preset threshold, the individual is determined to have crossed the edge of the swimming pool, and the number of people who have currently crossed the edge of the swimming pool is counted. Based on the remaining number of people in the swimming pool counted by the air conditioner indoor unit when the above steps were performed last time, the corresponding addition and subtraction operations are performed in combination with the number of people who have currently crossed the edge of the swimming pool. The first number of individuals obtained can be used to represent the ideal value of the remaining number of people in the current swimming pool.

[0068] The size of the preset threshold depends on the amount of change in the center coordinates of the human body during the process of the individual stepping into / out of the boundary, and the embodiment of the present invention does not make any specific limitation to this.

[0069] Figure 2 Schematic diagram of the effect of the radar module provided by the present invention on human body perception. Figure 2 As shown, for example, if it is assumed that the direction in which the individual steps out perpendicular to the longitudinal boundary is the positive direction of the X-axis, the difference (a positive value) between the X-axis coordinate value in the center coordinates of the human body analyzed by the radar module at the previous sampling time and the X-axis coordinate value in the center coordinates of the boundary is recorded as the preset threshold. If the difference (a positive value) between the X-axis coordinate value in the center coordinates of the boundary and the X-axis coordinate value in the center coordinates of the human body analyzed by the radar module at the current sampling time is less than or equal to the preset threshold, it is determined that the individual has stepped out of the boundary along the positive direction of the X-axis, and the number of individuals meeting this condition is subtracted from the remaining number of people in the swimming pool.

[0070] Similarly, the difference (negative value) between the X-axis coordinate value in the center coordinate of the human body analyzed by the radar module at the previous sampling time and the X-axis coordinate value in the center coordinate of the boundary is recorded as the preset threshold. If the difference (negative value) between the X-axis coordinate value in the center coordinate of the boundary and the X-axis coordinate value in the center coordinate of the human body analyzed by the radar module at the current sampling time is greater than or equal to the preset threshold, it is determined that the individual has crossed the boundary along the negative direction of the X-axis, and the number of individuals meeting this condition is added to the remaining number of people in the swimming pool.

[0071] It is understandable that in addition to relying on existing tracking algorithms, the above process can also use the establishment of artificial intelligence models to detect, track and separate the human body.

[0072] Secondly, after counting the first number of individuals, the radar module is used to calculate and analyze the electromagnetic waves reflected by the human body on the water surface in the current swimming pool area, and the individuals currently obtained in different positions are counted. The second number of individuals obtained can be used to represent the actual value of the remaining number of people in the current swimming pool.

[0073] Finally, compare and analyze the number of the first individual and the number of the second individual:

[0074] If the number of the first individuals is equal to the number of the second individuals, it means that the statistical analysis results are consistent with the actual situation, and it is determined that no drowning incident has occurred in the swimming pool.

[0075] If the number of the first individual is greater than the number of the second individual, it means that the statistical analysis result does not conform to the actual situation, which means that there is an error in the statistical analysis of the cross-domain boundary. At this time, the actual situation of the swimming pool shall prevail, and the second individual number shall be directly overwritten to the first individual number counted this time, so that the next time the statistical analysis of the cross-domain boundary is performed, the number of people will be accumulated based on the corrected first individual number.

[0076] If the number of the first individuals is less than the number of the second individuals, it means that the statistical analysis results do not conform to the actual situation. This means that before the human body is sensed in the swimming pool area, there are individuals who hide their entire bodies under the water. It is necessary to further determine whether this is a drowning incident or a diving behavior based on the radar perception information.

[0077] The embodiment of the present invention compares a first number of individuals counted by the radar module based on the flow of human individuals passing through the boundary of the swimming pool, and a second number of individuals directly sensed by the radar module based on the actual remaining number of people in the swimming pool, so as to determine whether a drowning incident has occurred in the swimming pool by comparing the ideal value and the actual value of the remaining number of people in the swimming pool, thereby effectively improving the management and control of the swimming pool.

[0078] Based on any of the above embodiments, the air conditioner indoor unit senses the individuals crossing the boundary of the swimming pool area through the radar module, and performs the following steps when counting the number of the first individuals:

[0079] The air conditioner indoor unit retrieves the number of the third individual before the current step into and / or step out of the swimming pool area boundary.

[0080] The air conditioner indoor unit obtains the number of individual changes of the swimming pool area boundary, wherein the number of individual changes includes the number of entry individuals crossing from the outside of the swimming pool area to the inside of the swimming pool area through the swimming pool area boundary, and / or the number of exit individuals crossing from the inside of the swimming pool area to the outside of the swimming pool area through the swimming pool area boundary.

[0081] The air conditioner indoor unit calculates the first individual number after entering and / or stepping out of the swimming pool area boundary this time according to the third individual number and the individual change number.

[0082] It should be noted that the flow of people in the swimming pool includes human individuals stepping in and / or out of the swimming pool area boundary. In an actual environment, the change in the number of individuals in the swimming pool may be one or more combinations of the above-mentioned flow of people.

[0083] Specifically, before the flow of people in the swimming pool area caused by crossing in and / or out of the swimming pool area boundary occurs, the air conditioner indoor unit needs to first obtain the third individual number used to represent the original remaining number of people in the swimming pool before the flow of people occurs.

[0084] The number of each third individual is the ideal value of the remaining number of people calculated after the radar module senses and analyzes the number of people who have entered and / or stepped out of the boundary of the swimming pool area at the previous sampling time.

[0085] According to the change in the number of individuals in the swimming pool, the number of individuals corresponding to each flow of personnel is obtained in turn according to each situation of crossing into or out of the boundary of the swimming pool area.

[0086] Among them, the number of individual changes corresponding to the situation of crossing into the boundary of the swimming pool area is the number of individuals entering, and the number of individual changes corresponding to the situation of crossing out of the boundary of the swimming pool area is the number of individuals leaving.

[0087] Optionally, if the change in the number of individuals in the swimming pool is that the individual only crosses the boundary of the swimming pool area, the air conditioner indoor unit counts the number of individuals entering the swimming pool within the time period according to the order in which the individuals enter the swimming pool.

[0088] Optionally, if the change in the number of individuals in the swimming pool is only the situation of crossing the boundary of the swimming pool area, the air conditioner indoor unit counts the number of individuals who have left the swimming pool in the time period according to the order in which the individuals leave the swimming pool.

[0089] Optionally, if the change in the number of individuals in the swimming pool includes at least one crossing into the boundary of the swimming pool area and at least one crossing into the boundary of the swimming pool area, the air-conditioning indoor unit obtains the individual changes caused by each personnel flow in sequence according to the order of individuals entering and exiting the swimming pool, so as to calculate the total individual changes in the time period.

[0090] Finally, the air-conditioning indoor unit calculates the first individual number corresponding to each personnel flow according to the third individual number and the individual change number and each personnel flow in the individual number change situation.

[0091] The first individual number is used to determine the number of people remaining in the pool after one or more personnel flows. Each first individual number is the third individual number before the next personnel flow change.

[0092] The embodiment of the present invention is based on the original third individual number of the swimming pool, and by calculating the individual change number in the actual personnel flow situation, the remaining number of people in the swimming pool after the actual personnel flow situation occurs can be obtained in real time. The specific value of the remaining number of people in the swimming pool can be obtained, the accuracy of obtaining the remaining number of people in the swimming pool is improved, and the calculation result is not easily affected by equipment factors.

[0093] Based on any of the above embodiments, when the number of individual changes includes the number of individuals entering the swimming pool area from outside the swimming pool area to inside the swimming pool area through the swimming pool area boundary, the air conditioner indoor unit performs the following steps:

[0094] The air conditioner indoor unit receives the number of incoming individuals sent by the radar module.

[0095] The air conditioner indoor unit accumulates the number of individuals entering the swimming pool based on the third number of individuals to obtain the first number of individuals after entering the boundary of the swimming pool area this time.

[0096] Specifically, if the number of individuals in the swimming pool changes only by crossing the boundary of the swimming pool area, the air-conditioning indoor unit will accumulate the number of individuals entering each time an individual enters in the order in which the individuals enter, based on the number of the third individual, to obtain the first number of individuals after one or more entries.

[0097] The embodiment of the present invention is based on the number of individuals entering the swimming pool sensed by the radar when a human individual crosses the swimming pool boundary, and by adding the number of the third individual in the swimming pool, the first individual number after people continuously enter the swimming pool can be obtained in real time. The number of people in the swimming pool can be accurately obtained, the accuracy is improved, and interference caused by other factors can be avoided.

[0098] Based on any of the above embodiments, when the number of individual changes includes the number of exit individuals that cross the swimming pool area boundary from the inside of the swimming pool area to the outside of the swimming pool area, the air conditioner indoor unit performs the following steps:

[0099] The air conditioner indoor unit receives the number of individuals appearing sent by the radar module.

[0100] The air-conditioning indoor unit subtracts the number of entering individuals from the third number of individuals to obtain the first number of individuals after crossing the boundary of the swimming pool area this time.

[0101] Specifically, if the number of individuals in the swimming pool changes by only crossing the boundary of the swimming pool area, the air-conditioning indoor unit will subtract the number of individuals counted each time an individual exits according to the order in which the individuals exit, based on the number of the third individual, to obtain the first number of individuals after one or more individual exits.

[0102] Preferably, if the change in the number of individuals in the swimming pool includes at least one crossing into the boundary of the swimming pool area and at least one crossing into the boundary of the swimming pool area, the air-conditioning indoor unit obtains the number of individuals entering or exiting each time personnel flow occurs in sequence according to the order of entry and exit of the individuals, and performs addition or subtraction calculations on the basis of the third number of individuals in accordance with the order of the personnel flow, to obtain the first number of individuals after the implementation of the working condition.

[0103] The embodiment of the present invention is based on the number of individuals sensed by the radar when a human individual steps out of the swimming pool boundary, and by subtracting the number of individuals from the third person in the swimming pool, the first number of individuals after people continuously exit the swimming pool can be obtained in real time. The number of people in the swimming pool can be accurately obtained, the accuracy is improved, and interference caused by other factors can be avoided.

[0104] Based on the content of any of the above embodiments, the air conditioner indoor unit performs the following steps when determining whether a drowning incident occurs in the swimming pool according to the first number of individuals and the second number of individuals:

[0105] The air conditioner indoor unit determines that a drowning incident occurs in the swimming pool area when it is determined that the number of the second individuals is always less than the number of the first individuals within a first preset time period.

[0106] The air conditioner indoor unit determines that a diving event exists in the swimming pool area when it is determined that the number of the second individuals changes from being less than the number of the first individuals to being equal to the number of the first individuals within a first preset time period.

[0107] Specifically, the air conditioner indoor unit needs to further determine whether the individual disappearing under the water surface is a drowning incident or a diving behavior based on the fixed first number of individuals and the second number of individuals that are perceived by the radar in real time and will change.

[0108] If the number of multiple groups of second individuals sensed by the radar module in real time within the first preset time period are all the same and continuously smaller than the number of the first individuals, it means that the individual that disappeared under the water did not come to the surface to breathe within the first preset time period. In this case, it is determined that the individual is submerged in water and has lost basic mobility, i.e., a drowning incident.

[0109] If the number of multiple groups of second individuals sensed by the radar module in real time within the first preset time period shows a floating change value, or is continuously less than the number of first individuals within the first preset time period and then becomes equal to the number of first individuals, it means that the individuals disappeared under the water surface intermittently come to the surface for breathing within the first preset time period, or, taking the individual with the strongest athletic ability as a reference, before this individual guides the surface for breathing, all other individuals hidden underwater have come to the surface, then it is determined that the individual actively holds his breath and swims underwater for as long as possible, and guides the surface for breathing before approaching the limit, which is a diving event.

[0110] The embodiment of the present invention uses the first number of individuals counted by the radar module through the flow of human individuals passing through the boundary of the swimming pool as a fixed value for reference, and compares the second number of individuals dynamically sensed by the radar module against the actual remaining number of people in the swimming pool within a first preset time period, so as to compare the fixed ideal value of the remaining number of people in the swimming pool with the actual value that fluctuates within the period, so as to identify whether the signal of a human body disappearing underwater belongs to a drowning incident or diving time, which can effectively improve the control of the swimming pool.

[0111] Based on any of the above embodiments, when the air conditioner indoor unit determines that the number of the second individuals is always less than the number of the first individuals within a preset time period, it determines that there is a drowning incident in the swimming pool area and then performs the following steps:

[0112] The air conditioner indoor unit sends out an alarm signal for drowning incidents in the swimming pool area.

[0113] The air conditioner indoor unit cancels the alarm signal when it is determined that the number of the second units changes from being less than the number of the first units to being equal to the number of the first units within a second preset time period.

[0114] Specifically, when the air conditioner indoor unit determines through the above steps that a drowning incident is currently occurring in the swimming pool area, it sends out an alarm signal for prompting that someone is drowning.

[0115] In the process of the second number of individuals changing over time, if the second number of individuals changes from being less than the first number of individuals to being equal to the first number of individuals after the second preset time, the broadcast of the alarm signal is cancelled. On the contrary, if the second number of individuals remains unchanged and remains less than the first number of individuals after the second preset time, the broadcast of the alarm signal is strengthened to attract the attention of the staff.

[0116] The alarm signal may be in the form of text information, buzzer or LED indicator light, etc. The present invention does not specifically limit the form of the alarm signal.

[0117] For example, the alarm signal may be a text message with the content “Alert! Someone is drowning in the swimming pool.” The controller of the air conditioner indoor unit encapsulates the information and sends it to the audio device on the air conditioner indoor unit or the remote terminal in the control center by wireless communication technology (Wi-Fi).

[0118] The embodiment of the present invention decides to send out an alarm signal when a drowning incident is determined to have occurred, and over time, when it is determined that the number of the second individuals has recovered to be equal to the number of the first individuals within a second preset time period, decides to cancel the alarm signal. The alarm signal is used to warn of dangerous situations such as drowning, so as to form a complete information prompt system, which can facilitate real-time knowledge of the safety of people in the swimming pool.

[0119] Figure 3 FIG. 1 is one of the flow charts of the control method of the air conditioning system based on swimming pool safety warning provided by the present invention. Figure 3 As shown, based on any of the above embodiments, the control method of the air-conditioning system based on swimming pool safety warning provided by the embodiment of the present invention includes: step 301, sensing the individuals crossing the boundary of the swimming pool area through the radar module, and counting the first number of individuals.

[0120] It should be noted that the execution body of the control method of the air conditioning system based on swimming pool safety warning provided in the embodiment of the present invention is the control device of the air conditioning system based on swimming pool safety warning arranged in the air conditioning indoor unit in the swimming pool air conditioning system.

[0121] It should be noted that before step 301, the user needs to send an activation instruction through the transmission medium to activate the dehumidification mode of the air conditioner, so that the indoor unit of the air conditioner runs at the default wind speed of the mode and the outdoor unit runs at the default frequency of the mode.

[0122] Optionally, the user can use the control device to transmit activation instructions through wireless communication between the control device and the air-conditioning system, so that the air-conditioning system initializes the dehumidification mode and starts the radar module.

[0123] Optionally, the user can issue an activation command through voice interaction. The air-conditioning system receives the activation command, performs voice recognition, initializes the dehumidification mode, and starts the radar module.

[0124] Specifically, in step 301, the control device of the air conditioning system based on swimming pool safety warning arranged in the air conditioning indoor unit integrates the perception information belonging to the same individual collected by the radar module, and locates the human body center coordinates of the individual under the current posture contour, and then compares the human body center coordinates of any individual with the boundary center coordinates of each boundary line of the swimming pool area. When the difference between the horizontal coordinate value and / or the vertical coordinate value of the two is greater than the preset threshold, it is determined that the individual has crossed the edge of the swimming pool, and the number of people who have currently crossed the edge of the swimming pool is counted. Based on the remaining number of people in the swimming pool counted by the previous execution of the above steps by the air conditioning indoor unit, the corresponding addition and subtraction operations are performed in combination with the number of people who have currently crossed the edge of the swimming pool, and the first number of individuals obtained can be used to represent the ideal value of the remaining number of people in the current swimming pool.

[0125] Step 302: Receive the second number of individuals on the water surface in the swimming pool area collected by the radar module.

[0126] Specifically, in step 302, the control device of the air-conditioning system based on swimming pool safety warning, which is arranged in the indoor unit of the air-conditioning, uses the radar module to calculate and analyze the electromagnetic waves reflected by the human body on the water surface in the current swimming pool area, and counts the individuals currently acquired in different positions. The second number of individuals obtained can be used to represent the actual value of the remaining number of people in the current swimming pool.

[0127] Step 303: Determine whether a drowning incident occurs in the swimming pool according to the first number of individuals and the second number of individuals.

[0128] Specifically, in step 303, the control device of the air conditioning system based on swimming pool safety warning arranged in the air conditioning indoor unit compares and analyzes the first individual number and the second individual number:

[0129] If the number of the first individuals is equal to the number of the second individuals, it means that the statistical analysis results are consistent with the actual situation, and it is determined that no drowning incident has occurred in the swimming pool.

[0130] If the number of the first individual is greater than the number of the second individual, it means that the statistical analysis result does not conform to the actual situation, which means that there is an error in the statistical analysis of the cross-domain boundary. At this time, the actual situation of the swimming pool shall prevail, and the second individual number shall be directly overwritten to the first individual number counted this time, so that the next time the statistical analysis of the cross-domain boundary is performed, the number of people will be accumulated based on the corrected first individual number.

[0131] If the number of the first individuals is less than the number of the second individuals, it means that the statistical analysis results do not conform to the actual situation. This means that before the human body is sensed in the swimming pool area, there are individuals who hide their entire bodies under the water. It is necessary to further determine whether this is a drowning incident or a diving behavior based on the radar perception information.

[0132] Figure 4 FIG2 is a flow chart of the control method of the air conditioning system based on the swimming pool safety warning provided by the present invention. Figure 4 As shown, the embodiment of the present invention provides a specific implementation method of a control method of an air conditioning system based on swimming pool safety warning:

[0133] (1) After the air conditioner is activated, it first enters standby mode, and uses the air conditioning radar on the air conditioner indoor unit (the radar capture area is set to the swimming pool) to capture human targets and count the human targets within the swimming pool range.

[0134] (2) The radar detects individuals crossing the pool boundary and accumulates them based on the original number of people in the pool, as shown below:

[0135] If a people enter the boundary of the swimming pool, the number of the first individual is updated from N1→N1+a.

[0136] If b people leave the boundary of the swimming pool, the number of the first person is updated from N1→N1-b.

[0137] (3) The radar continues to directly sense the human body in the current swimming pool and obtains the second number of individuals N2 in the swimming pool.

[0138] (4) Compare N1 and N2. If N1 and N2 are equal, the statistical result is consistent with the actual situation, and all individual users are in a state of swimming on the water surface.

[0139] If N1 is greater than N2, the statistical results do not match the actual situation, and the radar's statistical results for entering and leaving the boundary are incorrect.

[0140] If N1 is smaller than N2, the statistical result is inconsistent with the actual situation, and there is at least one user whose body is completely hidden under the water.

[0141] (5) When N1 is less than N2, the radar continues to update N2 for human perception of the current swimming pool. If N2 returns to N1 after 1 minute, it is determined that the human target whose body is completely hidden under the water surface is swimming underwater. Otherwise, it is determined that the human target whose body is completely hidden under the water surface is drowning, and the air conditioner speaker is controlled to send out an alarm signal.

[0142] (6) Within 2 minutes after that, N2 returns to N1 and the alarm signal is cleared.

[0143] In the embodiment of the present invention, the radar module installed in the indoor unit of the air conditioner observes the swimming pool from a bird's-eye view, and analyzes the changes in the number of individuals when they enter and leave the swimming pool area, which is used as a basis for judging whether a drowning incident has occurred in the swimming pool. With the all-weather monitoring of the air conditioning system, accurate prevention and early warning can be carried out to prevent the occurrence of drowning incidents to the greatest extent, effectively improving the control of the swimming pool.
