Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and in particular to an air conditioning control method, device and air conditioning system based on a swimming pool. 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. Among the existing human-sensing-based air-conditioning intelligent control solutions, only the AI ​​technology solution based on face recognition can achieve accurate personnel type judgment. However, this type of solution not only requires high-definition cameras, but also requires the operation of face recognition algorithms, which will greatly increase the manufacturing cost of air conditioners and lead to a decline in the market competitiveness of related products.

[0003] As an alternative, radar sensing is a wireless sensing technology that processes and analyzes the received radar echoes of targets with human characteristics to obtain vital signs data such as breathing rate, heart rate and body movement. Millimeter wave radar is a radar that works in the millimeter wave (wavelength 1-10mm, frequency 30-300GHz) band. It is mostly used in air conditioners to realize functions such as turning on when people come, turning off when people leave, and no wind feeling. However, the vibration generated by the air conditioner itself during operation will affect the radar data collection and even cause blurred imaging. The longitudinal wave of longitudinal vibration will affect the vertical data collection of the target. Similarly, the transverse wave will affect the transverse data collection. If the amplitude is large, even the static target will be imaged as a moving target, which seriously affects the radar perception accuracy, and then causes the swimming pool air conditioner to misjudge the drowning situation in the swimming pool.

[0045] 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.

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.

[0047] 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.

[0048] 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.

[0049] Figure 1 FIG. 1 is one of the flow charts of the air conditioning control method based on a swimming pool provided by the present invention. Figure 1 As shown, the swimming pool-based air conditioning control method provided by the embodiment of the present invention includes: step 101, determining a first vibration wave based on a vibration sampling signal collected by a vibration sensor from an air conditioning indoor unit.

[0050] The vibration sampling signal is a vibration signal generated by the operation of the fan of the air conditioner indoor unit during the sampling period. The vibration sensor, the radar module and the vibration generator are all arranged in the air conditioner indoor unit. The vibration sensor is used to sense the vibration of the air conditioner indoor unit, and the vibration generator is used to eliminate the vibration of the radar module driven by the air conditioner indoor unit.

[0051] It should be noted that the execution subject of the swimming pool-based air-conditioning control method is a swimming pool-based air-conditioning control device, which can be arranged in an air conditioner.

[0052] The application scenario of the swimming pool-based air conditioning control method of the embodiment of the present invention is to use a vibration sensor to sense the changes in vibration waveforms generated by an air conditioner dedicated to a swimming pool under different wind speeds and modes, and use a vibration generator to emit an opposite waveform to offset the vibration caused by the radar module. The individual behavior in the swimming pool is monitored by the transmission of the radar module after vibration cancellation to avoid drowning incidents.

[0053] It should be noted that before step 101, since the swimming pool carries a large amount of water and the air humidity is relatively high, the application requirement is usually dehumidification, and it is necessary to send an activation command to the air conditioner through the transmission medium to activate the dehumidification mode of the air conditioner in the space where the swimming pool is located.

[0054] 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 conditioner initializes the dehumidification mode and starts the radar module.

[0055] Optionally, the user can issue an activation command through voice interaction. After the air conditioner receives the activation command and performs voice recognition, it initializes the dehumidification mode and starts the radar module.

[0056] Specifically, in step 101, after receiving and responding to the activation instruction of the dehumidification mode, the swimming pool-based air conditioning control device controls the fan of the air conditioning indoor unit to run at the speed of this mode, and controls the compressor of the air conditioning outdoor unit to run at the power of this mode.

[0057] Since the operation of the fan will cause its own vibration to propagate to the air-conditioning indoor unit and its internal components, the swimming pool-based air-conditioning control device periodically senses the vibration of the air-conditioning indoor unit through a vibration sensor, and fits the first vibration wave used to characterize the vibration degree of the air-conditioning based on the vibration sampling signal collected within a sampling period.

[0058] The sampling period refers to the working period of the vibration sensor for sensing, and its value is at least an integer multiple of the air conditioner vibration period, which is not specifically limited in the embodiment of the present invention.

[0059] It is understandable that the air conditioner dedicated to swimming pools can not only eliminate the vibration transmitted by the air conditioner indoor unit to correct the perception ability of the radar module, but also connect the compressor of the air conditioner outdoor unit with the heat exchanger of the swimming pool heat storage unit. After the air conditioner starts the dehumidification mode, the heat exchanger of the swimming pool heat storage unit can recover the heat energy of the outdoor unit to heat the swimming pool water.

[0060] Step 102: In the process of controlling the vibration generator to output the second vibration wave, the radar module analyzes the swimming pool behavior information captured by the radar module from the movement trajectory information of any individual in the swimming pool area to monitor the swimming pool safety.

[0061] The first vibration wave and the second vibration wave have the same period and amplitude, and the phase of the first vibration wave and the phase of the second vibration wave differ by half a period.

[0062] Specifically, in step 102, the swimming pool-based air conditioning control device retains the period and amplitude of the first vibration wave obtained in step 101, and delays its phase by half a period, and after obtaining a second vibration wave with a waveform opposite to that of the first vibration wave, controls the vibration generator to emit a vibration wave with the second vibration wave to continuously eliminate the vibration of the radar module.

[0063] While the vibration generator is continuously eliminating vibrations from the radar module, the swimming pool-based air-conditioning control device calculates and analyzes the electromagnetic waves reflected by individuals on the water surface of the swimming pool area through the vibration-eliminating radar module, and integrates the position information of the target individual in the swimming pool obtained at different times into the motion trajectory information of the individual in the swimming pool, and uses the motion trajectory information to analyze the individual's swimming pool behavior information, which serves as the basis for judging swimming pool safety monitoring.

[0064] Among them, the position information recorded by the trajectory point corresponding to any moment in the motion trajectory information is not empty, which means that the individual's body is partially exposed to the water surface at this time, and the swimming pool behavior information corresponding to the instantaneous action can point to swimming behavior or landing behavior after diving.

[0065] The position information recorded in the trajectory point corresponding to any moment in the motion trajectory information is empty, which means that the individual's body is completely hidden on the water surface at this time, or the individual has left the swimming pool. The swimming pool behavior information corresponding to the instantaneous action can be a diving behavior or a resting behavior after leaving the swimming pool.

[0066] The embodiment of the present invention does not specifically limit the type and quantity of radar sensing devices in the radar module.

[0067] Among them, the radar module may include a laser radar, infrared sensor, etc.

[0068] Preferably, 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 meter, 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.

[0069] Therefore, the swimming pool air conditioning system collects the real-time position information of individuals on the water surface of the swimming pool area based on the millimeter-wave radar to analyze the movement trajectory of each individual in the swimming pool over time.

[0070] Exemplarily, the radar module may include multiple sensor elements such as millimeter wave radar, lidar, infrared sensor, etc. The swimming pool air conditioning system integrates the individual position information collected by each sensor element to comprehensively depict the movement trajectory of each individual in the swimming pool over time.

[0071] In the embodiment of the present invention, the vibration generator emits a second vibration wave opposite to the actual first vibration wave to eliminate the vibration transmitted by the indoor unit of the air conditioner, and the radar module in the vibration elimination state monitors the movement trajectory information of the individual in the swimming pool in real time to analyze the swimming pool behavior information, and judges the swimming pool safety incident accordingly. The vibration wave emitted by the vibration transmitter and the vibration wave generated by the air conditioner itself during operation can be superimposed and eliminated, so that the air conditioner radar can form a stable image during observation, and the control accuracy of the air conditioner is further improved on the basis of improving the perception accuracy of the air conditioner radar, effectively improving the control of the swimming pool.

[0072] On the basis of any of the above embodiments, in the process of controlling the vibration generator to output the second vibration wave, the swimming pool safety is monitored by analyzing the swimming pool behavior information from the motion trajectory information captured by the radar module for any individual in the swimming pool area, including: when it is determined that the motion trajectory information of the target individual by the radar module after the second vibration wave is eliminated does not add new trajectory points within a preset time period, the swimming pool behavior information of the target individual is determined as diving behavior.

[0073] The target individual is any human individual in the swimming pool area. The radar module after the vibration is eliminated by the second vibration wave cancels the vibration of the radar module caused by the first vibration wave under the propagation of the air conditioner indoor unit by the second vibration wave having a phase difference of half a cycle with the first vibration wave.

[0074] It should be noted that Figure 2 FIG. 1 is a schematic diagram of the principle of vibration elimination of the radar module provided by the present invention. Figure 2 As shown, taking the first vibration wave as a sine wave and the second vibration wave as a cosine wave as an example, an implementation process of using the second vibration wave to eliminate vibration of the radar module is given:

[0075] During the operation of the indoor unit of the air conditioner, the vibration waveform is similar to the resonant wave, but the amplitude of each cycle is different and there is a slight difference. Therefore, the first vibration wave (sin(·)) can be fitted by collecting vibration signals of multiple vibration cycles. Since the second vibration wave has a phase difference of half a cycle with the first vibration wave, its waveform is completely opposite to the first vibration wave, that is, (cos(·)). At any time point, the sum of the vibration amplitude value cos(x) corresponding to the second vibration wave and the vibration amplitude value sin(x) corresponding to the first vibration wave is 0, so the vibration of the indoor unit of the air conditioner can be offset.

[0076] Specifically, in step 102, the air conditioning control device based on the swimming pool uses the radar module after vibration elimination to analyze the position information recorded by each track point in the motion track information of the target individual when swimming in the swimming pool in descending time sequence:

[0077] If the radar signal disappears continuously within the subsequent preset time period up to the last non-empty trajectory point in the motion trajectory information of the target individual, that is, the location information recorded at the corresponding trajectory point is empty, it will not be counted as a valid trajectory point in the motion trajectory information. If the user does not expose his entire body outside the swimming pool at this time, it can be determined that the target individual's pool behavior information changes from the original swimming behavior to the diving behavior at the moment corresponding to the last non-empty trajectory point in the motion trajectory information, that is, the target individual's pool behavior information is updated to the diving behavior.

[0078] Therefore, the air conditioning control device based on the swimming pool needs to extract the historical trajectory points within a period of time before the radar signal disappears from the motion trajectory information of the target individual. According to the principle that a series of actions before diving are all preparations for diving, the instantaneous motion state presented by the last historical trajectory point before entering the water is used as the initial motion state of the diving behavior to predict the diving displacement that occurs during the period when the radar signal disappears.

[0079] If the target individual's entire body is exposed outside the swimming pool until the last empty trajectory point in the target individual's motion trajectory information, it can be determined that the target individual has changed from the original swimming behavior to the resting behavior of leaving the swimming pool at the moment corresponding to the last non-empty trajectory point in the motion trajectory information. At this time, there is no need for the radar module to track the target individual until the target individual re-enters the water and the motion trajectory is monitored again.

[0080] If the radar signal disappears intermittently and again within the first preset time period before the last non-empty trajectory point in the target individual's motion trajectory information, the trajectory points whose position information is not empty in the swimming pool will be counted as valid trajectory points in the motion trajectory information. In addition, in the process of the radar signal disappearing intermittently and again, firstly, the time when the radar signal disappears is too short to determine whether the individual has engaged in diving behavior, and secondly, the number of valid trajectory points before the radar signal disappears is too small, so even if the user has engaged in a short period of diving behavior, it is impossible to provide effective evidence for judgment. Therefore, the user behavior of the target individual is still regarded as swimming behavior on the surface of the swimming pool, that is, the swimming pool behavior information of the target individual is updated to swimming behavior, until the radar signal of the target individual disappears continuously due to being underwater for a long time, and then the diving displacement is predicted.

[0081] The displacement magnitude of the diving displacement is determined based on the moving speed of the target individual before entering the water and the prediction period, and the moving direction of the target individual before entering the water is set as the displacement direction of the diving displacement.

[0082] The moving speed and moving direction of the target individual before entering the water are determined based on the historical trajectory points before entering the water extracted from the motion trajectory information.

[0083] Specifically, it should be noted that the prediction period refers to the estimated duration of the target individual diving behavior after the radar signal disappears.

[0084] Specifically, after the swimming pool-based air-conditioning control device determines that the swimming pool behavior information of the target individual is currently updated to diving behavior, the diving direction continues to use the moving direction before entering the water, and uses the moving speed of the target individual before entering the water as the diving speed. Assuming that the target individual dives at a constant speed during the prediction period, the product of the two is used to estimate the diving displacement that occurs during this period.

[0085] The diving displacement is used to compare the water exit position of the target individual in the diving behavior to determine whether the target individual whose swimming pool behavior information is the diving behavior has a drowning incident.

[0086] Specifically, the swimming pool-based air-conditioning control device uses a vibration-damped radar module to monitor the water exit point position of the target individual after a prediction period. If the displacement fitted by the water exit point position information and the water entry point position information matches the diving displacement, it is determined that no safety accident has occurred. Otherwise, it is determined that the target individual has drowned after diving, and an acoustic and light signal is output to issue a drowning alarm.

[0087] The embodiment of the present invention monitors the movement trajectory information of the individual in the swimming pool in real time through the radar module after vibration elimination. When it is determined that no new trajectory points have been added in the movement trajectory information, the average speed of the target individual before entering the water is used to represent the overall movement level of the individual during the diving process. The movement trajectory of the individual before the whole body enters the water can be used as a basis to predict the diving movement trend of the individual after the whole body enters the water, which overcomes the defect that the radar cannot capture the human body parts below the water surface to a certain extent, and provides guidance for the air conditioner to monitor the safety of divers.

[0088] Based on any of the above embodiments, after determining the swimming pool behavior information of the target individual as a diving behavior, it also includes: sensing the individuals crossing the boundary of the swimming pool area by using the radar module after the second vibration wave is damped, and counting the first number of individuals.

[0089] Specifically, the swimming pool-based air conditioning control device can also integrate the perception information belonging to the same individual collected by the radar module after vibration elimination, and locate the body center coordinates of the individual under the current posture contour, and then compare 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, 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 swimming pool-based air conditioning control device 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, 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.

[0090] The second number of individuals is obtained by using the radar module after the second vibration wave is damped to sense the individuals on the water surface in the swimming pool area.

[0091] Specifically, in step 302, the swimming pool-based air conditioning control device uses the vibration-damped 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.

[0092] It is determined whether a drowning incident occurs to a target individual whose swimming pool behavior information is diving behavior according to the first individual number and the second individual number.

[0093] Specifically, the air conditioning control device based on the swimming pool compares and analyzes the first individual number and the second individual number:

[0094] Under the premise of determining the number of individuals with diving behavior in the swimming pool through the individual's motion trajectory information, if the first number of individuals is greater than the second number of individuals, and the difference between the two is equal to the number of individuals with diving behavior, it means that the users in the swimming pool have not left, and it is not possible to perceive that all individuals have switched from swimming to diving. The statistical analysis results are consistent with the actual situation, and it is determined that no drowning incident has occurred in the swimming pool. On the contrary, if the first number of individuals is greater than the second number of individuals, and the difference between the two is greater than the number of individuals with diving behavior, it is determined that a drowning incident has occurred in the swimming pool.

[0095] If the number of the first individual is not 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 number of the second individual shall be directly overwritten to the number of the first individual 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 number of the first individual.

[0096] The embodiment of the present invention analyzes the number of individuals diving according to the individual movement trajectory and the change in the number of individuals when they enter and leave the swimming pool area through the radar module after vibration cancellation, and uses this as the basis for distinguishing diving behavior from drowning incidents in the swimming pool. It can prevent the occurrence of drowning incidents to the greatest extent and effectively improve the control of the swimming pool.

[0097] Based on any of the above embodiments, the radar module after the second vibration wave is damped is used to sense the individuals crossing the boundary of the swimming pool area and count the first number of individuals, including: retrieving the third number of individuals before crossing into and / or out of the boundary of the swimming pool area.

[0098] 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 swimming pool-based air conditioning control device needs to first obtain a third individual number used to characterize the original remaining number of people in the swimming pool before the flow of people occurs.

[0099] The number of each third individual is the ideal value of the remaining number of people calculated by sensing and analyzing the number of people who have entered and / or stepped out of the boundary of the swimming pool area in the previous working cycle by the radar module after vibration cancellation.

[0100] The number of individual changes in the swimming pool area boundary is obtained by utilizing the radar module after the second vibration wave is damped, and the number of individual changes includes the number of individuals entering the swimming pool area from the outside to the inside of the swimming pool area through the swimming pool area boundary, and / or the number of individuals leaving the swimming pool area from the inside to the outside of the swimming pool area through the swimming pool area boundary.

[0101] Specifically, the swimming pool-based air-conditioning control device obtains the number of individuals corresponding to each flow of personnel in turn according to the change in the number of individuals in the swimming pool according to the vibration-damped radar module and each situation of crossing into or out of the boundary of the swimming pool area.

[0102] 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.

[0103] 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.

[0104] 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.

[0106] The first individual number after this stepping into and / or out of the swimming pool area boundary is calculated based on the third individual number and the individual change number.

[0107] Specifically, the swimming pool-based air conditioning control device calculates the first individual number corresponding to each flow of personnel according to the third individual number and the individual change number and each flow of personnel in the change of the individual number.

[0108] The first number of individuals is used to determine the number of people remaining in the swimming pool after one or more personnel flows occur. Each first number of individuals is the third number of individuals before the next personnel flow change. The embodiment of the present invention does not specifically limit the statistical method of the first number of individuals.

[0109] Optionally, if the number of individuals in the swimming pool changes only by crossing the boundary of the swimming pool area, the air-conditioning control device of the swimming pool will add up the number of individuals entering each time an individual enters, based on the third number of individuals, according to the order in which the individuals enter.

[0112] 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.

[0113] Based on any of the above embodiments, the first vibration wave is determined based on the vibration sampling signal collected by the vibration sensor from the air conditioner indoor unit, including: obtaining an average sampling period according to multiple vibration periods contained in the vibration sampling signal, and obtaining an average sampling amplitude according to the vibration amplitude corresponding to the target sampling point in each vibration period.

[0114] The target sampling points include peak sampling points and / or trough sampling points within the sampling period.

[0115] Specifically, in step 101, the air conditioning control device based on the swimming pool averages the vibration sampling signal that is periodically floating and changing at a specific target sampling point within the sampling period to obtain an average sampling period and an average sampling amplitude that can characterize the overall vibration level. The calculation formula is as follows:

[0116]

[0117]

[0118] Where T is the average sampling period, A is the average sampling amplitude. n is the number of vibration periods included in the sampling period, T i is the i-th vibration cycle in the sampling period. For any vibration cycle, if the target sampling point is the peak sampling point and the trough sampling point in the vibration cycle, then in the i-th vibration cycle, A j It can be the peak amplitude value corresponding to the peak sampling point in the vibration cycle, in which case j = 2i-1. j It can be the amplitude valley value corresponding to the valley sampling point in the vibration period, and in this case j=2i.

[0119] The first vibration wave is generated based on the average sampling period and the average sampling amplitude.

[0120] Specifically, the swimming pool-based air conditioning control device uses the average sampling period T and the average sampling amplitude A as new period and amplitude, respectively, to reconstruct the first vibration wave after stabilizing the vibration of the indoor unit.

[0121] The embodiment of the present invention averages multiple vibration cycles contained in the vibration sampling signal and the vibration amplitude that fluctuates at the target sampling point within each vibration cycle, and reconstructs the first vibration wave used to characterize the stable vibration level using the obtained average sampling cycle and average sampling amplitude. It can stabilize the vibration waves emitted by the air conditioner itself during operation, provide a reasonable reference value for subsequent superposition and vibration elimination, and greatly improve the perception accuracy of the air conditioner radar.

[0122] Based on any of the above embodiments, if the target sampling point is a sampling point other than the peak sampling point and the trough sampling point in the vibration period, the value of the target sampling point in the time domain includes and

[0123] Here, k is a positive integer greater than 2.

[0124] Specifically, if the target sampling point is any sampling point other than the peak sampling point and the trough sampling point within the vibration period That is, in any vibration cycle, There are 3 more sampling points with the same absolute value of the amplitude of the sampling point, namely and but.

[0125]

[0126] in, For sampling point The average sampling amplitude at and are respectively the mth vibration period and The amplitude corresponding to the sampling point with the same absolute value of the amplitude of the sampling point.

[0127] Then, the air conditioning control device based on the swimming pool uses other sampling points based on the average sampling amplitude A obtained by averaging the peak and trough values. The average sampling amplitude obtained by averaging To reconstruct the first vibration wave.

[0128] Figure 3 FIG. 2 is a flow chart of the swimming pool-based air conditioning control method provided by the present invention. Figure 3 As shown, the embodiment of the present invention provides a specific implementation of an air conditioning control method based on a swimming pool:

[0129] (1) After activating the air conditioner, it first enters standby mode and uses the air conditioner radar on the air conditioner indoor unit to capture human targets. If there is someone in the swimming pool, steps (2)-(5) are executed, otherwise step (6) is executed.

[0130] (2) If there is someone, the dehumidification mode of the air conditioner is kept on. During the heat exchange between the indoor unit and the outdoor unit of the air conditioner, the vibration sensor is used to sample the vibration of the indoor unit to obtain a first vibration wave.

[0131] (3) The vibration generator is controlled to output a second vibration wave to dampen the vibration transmitted to the radar module, and the radar after the damping is continued to capture the position of the human body in real time, and the motion curve of the human body during swimming (i.e., motion trajectory information) is fitted according to the real-time position of the target individual.

[0132] (4) If the human body signal sensed by the radar within the swimming pool suddenly disappears and lasts for a period of time, it is determined that the human body has entered a diving state and step (5) is continued.

[0133] If the human body signal sensed by the radar within the swimming pool range does not disappear continuously or never disappears, it is determined that the human body is still swimming, and the process jumps to step (2) to continue tracking the target individual by the radar.

[0134] (5) Extract the partial motion curve of the human body 3 seconds before diving, and use this curve to draw the slope and tangent of the curve at the last moment before diving. Calculate the diving displacement along the tangent direction (i.e., the movement direction of the target individual before entering the water). is the average speed of the human body in the 3 seconds before diving (i.e. the moving speed of the target individual before entering the water), and T is the prediction period (which can be set to 3 seconds).

[0135]

[0136]

[0137] Among them, t is any moment in the motion trajectory information, ΔT is the predicted cycle length before the human body dives, (X t ,Y t )for t The position of the target individual in the pool coordinate system at the moment, that is, the first historical trajectory point. (X t+ΔT ,Y t+ΔT ) is the position of the target individual in the pool coordinate system at time t+ΔT, that is, the last historical trajectory point. ΔR is the distance the target individual moves from time t to time t+ΔT. is the average moving speed of the target individual from time t to time t+ΔT. The average speed within the ΔT period is regarded as the initial moving speed of the target individual when diving. Its moving direction is the tangent direction of the curve formed by the motion trajectory information at time t+ΔT.

[0138] (6) If no one is present, the air conditioner will be activated in dehumidification mode for a short period of time within a preset time. If no one is present in the swimming pool area for a preset time, the air conditioner outdoor unit will automatically stop operating.

[0139] In the embodiment of the present invention, based on the average sampling amplitude obtained by averaging the peaks and valleys, the average sampling amplitude obtained by averaging other sampling points is also used to reconstruct the first vibration wave. This can eliminate the interference of extreme values ​​in the process of stabilizing the vibration waves emitted by the air conditioner itself during operation, thereby improving the linear fitting accuracy.

[0151] The diving trajectory tracking unit is used to determine the displacement size of the diving displacement based on the moving speed of the target individual before entering the water and the prediction period, and set the moving direction of the target individual before entering the water as the displacement direction of the diving displacement.

[0152] The drowning judgment unit is used to compare the water exit point position of the target individual in the diving behavior with the diving displacement to judge whether the target individual whose swimming pool behavior information is the diving behavior has a drowning incident.

[0153] Among them, the target individual is any human individual in the swimming pool area; the moving speed and moving direction of the target individual before entering the water are determined based on the historical trajectory points before entering the water extracted from the motion trajectory information; the radar module after the vibration is eliminated by the second vibration wave uses a second vibration wave that has a phase difference of half a cycle with the first vibration wave to offset the vibration of the radar module caused by the first vibration wave under the propagation of the air-conditioning indoor unit.

[0154] Optionally, the air conditioning control module 420 further includes a first statistical unit, a second statistical unit and a drowning determination unit, wherein:

[0155] The first statistical unit is used to sense the individuals crossing the boundary of the swimming pool area by using the radar module after the second vibration wave is damped, and count the first number of individuals.

[0156] The second statistical unit is used to sense the individuals on the water surface in the swimming pool area by using the radar module after the second vibration wave is damped, so as to obtain the second number of individuals.

[0168] The swimming pool-based air conditioning control device provided in an embodiment of the present invention is used to execute the above-mentioned swimming pool-based air conditioning control method of the present invention. Its implementation method is consistent with the implementation method of the swimming pool-based air conditioning control method provided by the present invention, and can achieve the same beneficial effects, which will not be repeated here.

[0169] In the embodiment of the present invention, the vibration generator emits a second vibration wave opposite to the actual first vibration wave to eliminate the vibration transmitted by the indoor unit of the air conditioner, and the radar module in the vibration elimination state monitors the movement trajectory information of the individual in the swimming pool in real time to analyze the swimming pool behavior information, and judges the swimming pool safety incident accordingly. The vibration wave emitted by the vibration transmitter and the vibration wave generated by the air conditioner itself during operation can be superimposed and eliminated, so that the air conditioner radar can form a stable image during observation, and the control accuracy of the air conditioner is further improved on the basis of improving the perception accuracy of the air conditioner radar, effectively improving the control of the swimming pool.

[0170] Figure 5 Schematic diagram of the structure of the air conditioner provided by the present invention. Figure 5 As shown, the air conditioning system provided by the embodiment of the present invention includes an air conditioning indoor unit 510 located in the swimming pool area, and an air conditioning outdoor unit 520 located in other spaces outside the swimming pool area.

[0171] The air conditioner indoor unit 510 is provided with a vibration reduction device 512 which is communicatively connected to the air conditioner controller 511 , and the vibration reduction device 512 includes a radar module 512 - 1 , a vibration generator 512 - 2 and a vibration sensor 512 - 3 which are communicatively connected to the air conditioner controller 511 , respectively.

[0172] The vibration sensor 512 - 2 is used to sense the vibration of the air conditioner indoor unit 510 . The vibration generator 512 - 3 is used to eliminate the vibration of the radar module 512 - 1 driven by the air conditioner indoor unit 510 .

[0173] The air conditioning controller 510 is used to implement the swimming pool-based air conditioning control method as described in any of the above items when executed, so as to control the vibration generator 512-3 to eliminate the vibration of the radar module 512-1, and then monitor the swimming pool safety by analyzing the swimming pool behavior information captured by the radar module 512-1 from the motion trajectory information of any individual in the swimming pool area.

[0174] Among them, the radar module 512-1 is a millimeter wave radar.

[0175] Specifically, the air-conditioning system can adjust the temperature and humidity of the space where the swimming pool area is located. The air-conditioning indoor unit 510 in the air-conditioning system is set in the space where the swimming pool area is located, so that the air-conditioning outdoor unit 520 compresses the low-temperature and low-pressure gas refrigerant transmitted by the air-conditioning indoor unit 510 into a high-temperature and high-pressure gas refrigerant, and then uses the corresponding dehumidification mode to adjust the temperature and humidity of the space where the swimming pool area is located.

[0176] The air conditioner indoor unit 510 is provided with an air conditioner controller 511 and a vibration elimination device 512 which are in communication connection. The air conditioner controller 511 is integrated in the control chip of the air conditioner system. When the air conditioner control method based on the swimming pool is executed, the vibration elimination device 512 is controlled to offset the vibration caused by the operation of the air conditioner indoor unit 510, and then human body perception is performed in the swimming pool area. The process is as follows:

[0177] The vibration elimination device 512 is composed of a radar module 512-1, a vibration generator 512-2 and a vibration sensor 512-3 which are arranged independently of each other. When the air conditioner indoor unit 510 activates the dehumidification mode, the fan operation will cause the vibration generated by itself to propagate to the air conditioner indoor unit 510 and its internal components. Therefore, the air conditioner controller 511 periodically senses the vibration generated by the air conditioner indoor unit 510 through the vibration sensor 512-3, and fits the first vibration wave used to characterize the vibration degree of the air conditioner according to the vibration sampling signal collected within a sampling period.

[0178] The air conditioning controller 511 retains the period and amplitude of the first vibration wave, and delays its phase by half a period, and after obtaining a second vibration wave with a waveform opposite to the first vibration wave, controls the vibration generator 512-2 to emit the second vibration wave to continuously eliminate the vibration of the radar module 512-1.

[0179] While the vibration generator 512-2 is continuously absorbing the vibration of the radar module 512-1, the air conditioning controller 511 calculates and analyzes the electromagnetic waves reflected by the individual on the water surface of the swimming pool area through the vibration-absorbing radar module 512-1, integrates the position information of the target individual in the swimming pool obtained at different times into the motion trajectory information of the individual in the swimming pool, and uses the motion trajectory information to analyze the individual's swimming pool behavior information, which serves as the basis for judging the safety monitoring of the swimming pool.

[0180] It is understandable that the embodiment of the present invention does not specifically limit the relative arrangement relationship of the components in the vibration reduction device 512.

[0181] Preferably, the radar module 512-1 is arranged between the vibration generator 512-2 and the vibration sensor 512-3, and the three are integrated on a back panel at a certain distance, so that the vibration sensed by the vibration sensor 512-3 is closest to the actual vibration of the radar module 512-1, and the vibration generator 512-2 can superimpose vibration cancellation on the basis of the actual vibration of the radar module 512-1, thereby reducing losses during the propagation process.

[0182] In the embodiment of the present invention, the vibration generator emits a second vibration wave opposite to the actual first vibration wave to eliminate the vibration transmitted by the indoor unit of the air conditioner, and the radar module in the vibration elimination state monitors the movement trajectory information of the individual in the swimming pool in real time to analyze the swimming pool behavior information, and judges the swimming pool safety incident accordingly. The vibration wave emitted by the vibration transmitter and the vibration wave generated by the air conditioner itself during operation can be superimposed and eliminated, so that the air conditioner radar can form a stable image during observation, and the control accuracy of the air conditioner is further improved on the basis of improving the perception accuracy of the air conditioner radar, effectively improving the control of the swimming pool.
