Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and in particular to a radar-based air conditioning control method, device and air conditioner. Background Art

[0002] With the continuous improvement of people's living standards, air conditioners have become a common electrical appliance in people's lives. Air conditioners are widely used in homes, office buildings, supermarkets, gymnasiums and other places. Existing air conditioners usually control the operation of the air conditioner according to the user's set parameters. For ordinary household air conditioners, the air conditioner runs according to the temperature and wind speed set by the user, which may cause inconsistencies with the current working conditions. For commercial air conditioners, they usually work in a unified control manner. The number of people in the application place may be different in different time periods, and human sensing devices are usually additionally set up for monitoring. 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 can obtain vital signs data such as breathing rate, heart rate and body movement of people by processing and analyzing the received target radar echo with human characteristics. 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 may misjudge the current working conditions and cause energy mismatch. Therefore, the control accuracy of existing air conditioners is poor, especially for users in public places such as office buildings, supermarkets, and gymnasiums. Summary of the invention

[0051] 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.

For example, the first object can be one or more.

[0053] 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.

[0054] 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.

[0055] Figure 1 FIG. 1 is one of the flow charts of the radar-based air conditioning control method provided by the present invention. Figure 1 As shown, the radar-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.

[0056] 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.

[0057] It should be noted that the execution subject of the radar-based air-conditioning control method is a radar-based air-conditioning control device, which can be arranged in an air conditioner.

[0058] The application scenario of the radar-based air-conditioning control method provided in the embodiment of the present invention is that when the user activates the air-conditioner, the vibration sensor is used to sense the changes in the vibration waveform generated by the air conditioner under different wind speeds and modes, and the vibration generator is used to emit an opposite waveform to offset the vibration caused by the radar module. When the radar module after vibration cancellation monitors that the individual's movement posture is a preset wake-up posture, after starting the posture control mode, the default air supply mode is adjusted to the air supply mode corresponding to the movement posture monitored by the radar in the posture control mode.

[0059] The radar module periodically collects information about all individuals in the room for monitoring at a specified time interval, and sends the profile information of each individual to the radar-based air conditioning control device. The embodiment of the present invention does not specifically limit the working cycle of the radar module.

[0060] Optionally, the radar module can perform collection operations in a default working cycle.

[0061] Optionally, the user can issue a cycle change instruction so that the radar module receives and responds to the instruction and changes the working cycle to the cycle indicated by the instruction to perform collection operations.

[0062] It should be noted that before step 101, the user needs to send an activation instruction through a transmission medium to activate the working mode of the air conditioner, so that the indoor cabinet 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.

[0063] 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 working mode and starts the radar module.

[0064] Optionally, the user can issue an activation command through voice interaction. The air-conditioning system receives the activation command, performs voice recognition, initializes the working mode, and starts the radar module.

[0065] Specifically, in step 101, after receiving and responding to the activation instruction, the radar-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.

[0066] Since the operation of the fan will cause its own vibration to propagate to the air-conditioning indoor unit and its internal components, the radar-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 degree of vibration of the air conditioner based on the vibration sampling signal collected within a sampling period.

[0067] 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.

[0068] Step 102: in the process of controlling the vibration generator to output the second vibration wave, if the radar module determines that the first posture information of at least one individual is a preset wake-up posture, and the duration of the wake-up posture reaches a preset threshold, the posture control mode is started.

[0069] 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.

[0070] Specifically, in step 102, the radar-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 the second vibration wave to continuously eliminate the vibration of the radar module.

[0071] While the vibration generator is continuously eliminating vibrations of the radar module, the radar-based air-conditioning control device uses the radar module after the vibration elimination to collect real-time human feature information from each individual in the large public space where the air conditioner is located, and analyzes the human morphological features contained therein. If the first posture information obtained by the analysis of any individual matches the pre-set wake-up posture, and the duration for which the individual maintains the wake-up posture reaches a preset threshold, it means that the individual's current behavioral intention is not to perform some specific movements in a public place with large space characteristics (such as a yoga studio, gymnasium, etc.), but to activate the posture control mode of the air conditioner by actively performing a wake-up action.

[0072] If the first posture information of any individual does not match the preset wake-up posture, or the duration for which the individual maintains the wake-up posture does not reach the preset threshold, it means that the individual's current behavioral intention is only to perform some specific movement movements in a public place with large space characteristics (such as a yoga studio, gymnasium, etc.), and the posture control mode will not be triggered.

[0073] The embodiment of the present invention does not specifically limit the type and quantity of radar sensing devices in the radar module.

[0074] Exemplarily, the radar module may include a laser radar, an infrared sensor, etc.

[0075] 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.

[0076] Therefore, the radar-based air-conditioning control device analyzes the user's individual behavior status based on the individual profile information collected in real time by the millimeter-wave radar.

[0077] Exemplarily, the radar module may include multiple sensor elements such as millimeter wave radar, lidar, infrared sensor, etc. The radar-based air-conditioning control device integrates the contour information collected by each sensor element to comprehensively depict the individual's real-time posture.

[0078] Step 103: Match a control strategy corresponding to the second posture information of the first target individual according to the posture library, so that the air conditioner can adjust the current default working mode according to the control strategy.

[0079] The first target individual is any one of the individuals in a wake-up posture in a large public space. The second posture information is determined by the first target individual based on the human feature information collected by the radar module from the first target individual after determining that the posture control mode has been started; the control strategy is used to adjust the control parameters in the default working mode, and the control parameters include at least one of the outlet temperature, outlet speed and swing mode.

[0080] It should be noted that the first target individual refers to an individual who continuously maintains the awakening posture in the current space to start the posture control mode, and the subjective action intention of the individual is to start the posture control mode.

[0081] The posture library is a process that includes multiple control trigger conditions for the posture control mode that have been set by the radar-based air-conditioning control device, and records the mapping relationship between the radar module executing different control strategies when monitoring individuals in various postures (or posture trajectories).

[0082] The control strategy is composed of a combination of adjustments made to different control parameters, and the control parameters involved include but are not limited to outlet air temperature, outlet air speed and swing air mode.

[0083] The outlet air temperature refers to the temperature of the cold or hot air blown out from the air outlet of the indoor cabinet of the air conditioner when the compressor of the outdoor unit is started. It can be increased or decreased based on the default cooling or heating working mode.

[0084] The air outlet speed refers to the speed when the fan of the indoor cabinet is started. The higher the wind speed, the greater the indoor heat exchange and the better the effect. Therefore, it can be increased or decreased based on the default working mode.

[0085] The swing wind mode refers to the air conditioner's blade assembly swinging by the movement of a motor, thereby changing the wind direction and achieving swing wind. The swing speed and range of the blade assembly can be adjusted based on the default working mode.

[0086] Specifically, in step 103, after determining that the posture control mode has been turned on, the radar-based air-conditioning control device uses the vibration-damped radar module in this mode to preferentially continue posture monitoring of the first target individual that starts the posture control mode, and uses the second posture information collected from it as retrieval information to perform query matching in the posture library, and the results are divided into two types: successful matching and failed matching.

[0087] A successful match means that the posture displayed by the individual in the posture control mode matches the information stored in the locally stored posture library, which means that the individual's current posture can trigger the control strategy preset in this mode. Therefore, the control strategy corresponding to the second posture information can be extracted according to the mapping relationship stored in the posture library.

[0088] Matching failure means that the posture displayed by the individual in the posture control mode does not match any information in the locally stored posture library, which means that the individual's current posture can trigger the control strategy preset in this mode, and the control strategy needs to be triggered with the correct posture.

[0089] 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 propagated by the indoor unit of the air conditioner. When the radar module after the vibration elimination detects that the first posture information of at least one individual shows a trend of continuously maintaining the awakening posture, the posture control mode is activated, and the radar module continues to capture the second posture information displayed by the individual activating the mode. When the control condition is triggered, the original working mode is adjusted using the control strategy corresponding to the second posture information. 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 to enable stable imaging during air conditioner radar observation, so that when the user is engaged in sports activities in a large public space, the working state of the air conditioner can be adjusted according to the posture change in the awakened posture control mode, without the need for the user to manually set the parameter adjustment, while reducing the control delay and improving the perception accuracy and control accuracy of the air conditioner, and taking into account the user's sports experience and the use experience of the air conditioner.

[0090] Based on any of the above embodiments, after the posture control mode is started, it also includes: when it is determined by using the radar module after the second vibration wave is damped that the third posture information of each individual does not match the posture library, the posture control mode is turned off.

[0091] Among them, the third posture information is determined in the posture control mode according to the human body feature information collected by the radar module for each individual within a preset time period; the radar module after using the second vibration wave to eliminate the vibration is offset by the second vibration wave that has a phase difference of half a cycle with the first vibration wave, thereby offsetting the vibration of the radar module caused by the first vibration wave under the propagation of the air-conditioning indoor unit.

[0092] 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:

[0093] 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.

[0094] Specifically, in step 102, after determining that the attitude control mode has been turned on, the radar-based air-conditioning control device can also use the vibration-damped radar module to continuously monitor the attitudes of all individuals in this mode. When it is determined that the third attitude information collected from the individual that started the attitude control mode and the remaining individuals in the space within a preset time period fails to match the attitude library, the attitude control mode is turned off and the radar module is operated for monitoring in a low-energy state.

[0095] The embodiment of the present invention continues to use the radar module after vibration elimination to monitor individual postures in the determined posture control mode. When the third posture information captured for each individual fails to trigger the control conditions of the posture library, the posture control mode is turned off, so that the air conditioner still maintains the original working mode. When the user is engaged in sports activities in a large public space, if there is no posture change that matches the preset control conditions after waking up the posture control mode, the posture control mode is automatically put into a dormant state, thereby reducing unnecessary energy consumption.

[0096] Based on any of the above embodiments, the method further includes: receiving and responding to a setting instruction issued by the second target individual, and starting a posture library setting mode.

[0097] The second target individual is any one of the individuals in a large public place.

[0098] It should be noted that the second target individual is any individual in a large public space, and the subjective action intention of the individual is to enter the action and formulate the strategy in the posture library corresponding to the posture control mode.

[0099] Specifically, after step 101 and before step 102, the radar-based air conditioning control device can also receive a setting instruction transmitted by the second target individual through a control terminal or direct touch, and start the posture library setting mode in response to the setting instruction.

[0100] The human body feature information of the second target individual monitored by the radar module after the second vibration wave is eliminated during the action collection period is analyzed, and the analyzed control posture information corresponding to the target control strategy is stored in the posture library.

[0101] The control strategy corresponds to the action collection cycle one by one, and the target control strategy is any one of the control strategies. The radar module after the second vibration wave is de-vibrated is to offset 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.

[0102] It should be noted that, in the posture library setting mode, a motion collection cycle is set correspondingly for the formulation process of each control strategy, so as to capture the posture or posture trajectory of the corresponding control strategy within the cycle.

[0103] Specifically, after determining that the posture library setting mode is started, the radar-based air-conditioning control device receives the human feature information collected by the radar module in real time on the second target individual during any action collection cycle, analyzes the human morphological features contained therein, and stores the control posture information obtained by the analysis in the posture library under the field of the target control strategy corresponding to the action collection cycle.

[0104] When it is determined that the control posture information corresponding to all control strategies has been stored in the library, the air conditioner is controlled to give an audible and visual prompt according to the notice signal that the posture library setting mode has been completed.

[0105] Specifically, when the radar-based air-conditioning control device determines that the control posture information corresponding to all control strategies is stored in the posture library, it controls the air conditioner to output a notification signal.

[0106] The notification signal may be one or more types of sound signal, light signal or vibration signal, and the embodiment of the present invention does not specifically limit its type and signal composition. The notification signal is used to convey information that the gesture library setting mode has been completed to the user in the space.

[0107] The embodiment of the present invention receives and responds to the setting instructions, and completes the collection and storage of the control posture information that triggers the corresponding control strategy in each action collection cycle in turn, until the triggering postures of all control strategies are entered, thereby completing the setting of the posture library before starting the posture control mode, so as to trigger the adaptive adjustment of the working mode of the air conditioner according to the posture in the future, thereby realizing the intelligent control of the air conditioner.

[0108] On the basis of any of the above embodiments, the human feature information monitored by the radar module of the second target individual during the motion acquisition period using the second vibration wave is analyzed, and the control posture information corresponding to the target control strategy is stored in the posture library, including: determining the key point position information based on the human feature information monitored by the radar module of the second vibration wave after the second vibration wave is eliminated.

[0109] Specifically, the radar-based air conditioning control device detects the human feature information monitored by the second target individual according to the radar module after vibration elimination, locates and identifies key points of the human body such as joints, facial features, and the key point position information corresponding thereto.

[0110] Coordinate system conversion and standardization operations are performed on the key point position information to obtain control posture information corresponding to the target control strategy.

[0111] Specifically, the radar-based air-conditioning control device converts and standardizes the key point position information belonging to the same individual, connects them in joint sequence to obtain the posture of the human body when setting the target control strategy, and outputs it as control posture information.

[0112] It is understandable that there are two main directions for multi-person human skeleton key point detection, one is top-down and the other is bottom-up. The top-up human skeleton key point positioning algorithm mainly includes two parts, human detection and single-person human skeleton key point detection, that is, first detect each person through the target detection algorithm, and then perform human skeleton key point detection for a single person based on the detection frame. Representative algorithms include G-RMI, CFN, RMPE, Mask R-CNN, and CPN. The current best effect on the MSCOCO dataset is 72.6%; the bottom-up method also includes two parts, key point detection and key point clustering, that is, first all the key points in the picture need to be detected, and then all the key points are clustered into different individuals through relevant strategies. Representative algorithms for modeling the relationship between key points include PAF, Associative Embedding, Part Segmentation, Mid-Range offsets, and the current best effect on the MSCOCO dataset is 68.7%.

[0113] The embodiment of the present invention uses the human feature information of the second target individual monitored by the radar module after vibration elimination to globally extract the key point position information of the human body, and then maps the key points to different human individuals to obtain the input control posture information corresponding to the target control strategy set for the individual. It can realize the human-computer interaction scene, bring more convenience to the user's air supply control during exercise, and improve the user experience.

[0114] Based on any of the above embodiments, the gesture library includes first control gesture information, second control gesture information, third control gesture information and fourth control gesture information.

[0115] The first control posture information is that the left arm is raised or pressed down unilaterally to increase or decrease the air outlet temperature.

[0116] The second control posture information is that the right arm is raised or pressed down unilaterally to increase or decrease the wind speed.

[0117] The third control posture information is that the two arms are raised up or pressed down in opposite directions to adjust the execution angle of the vertical swing leaf assembly.

[0118] The fourth control posture information is that both arms are raised upward or pressed downward to adjust the execution angle of the swing leaf assembly.

[0119] Specifically, the radar-based air conditioning control device may pre-store first control posture information, second control posture information, third control posture information, and fourth control posture information in the posture library in the posture library setting mode.

[0120] The embodiment of the present invention does not specifically limit the form in which the user enters different trigger gestures for different control strategies in the gesture library setting mode.

[0121] For example, a human body standing with both hands flat is set as a wake-up posture as an example of a posture control mode that can trigger an air conditioner, and a set of control posture information pre-set for the posture library and its corresponding control strategy are given:

[0122] Optionally, the first control posture information may be that the left arm is unilaterally raised or pressed down. Accordingly, the corresponding control strategy is mainly used to adjust the outlet air temperature. The embodiment of the present invention does not specifically limit the adjustment method.

[0123] For example, when the first control posture information is that the left arm is raised unilaterally, the control strategy may be that the air outlet temperature rises by 1° C. for every second that the posture is maintained.

[0124] If the first control posture information is that the left arm is pressed down unilaterally, the control strategy may be that the air outlet temperature drops by 1°C for every second that the posture is maintained.

[0125] Optionally, the second control posture information may be that the right arm is unilaterally raised or pressed down. Accordingly, the corresponding control strategy is mainly used to adjust the wind speed. The embodiment of the present invention does not specifically limit the adjustment method.

[0126] For example, when the second control posture information is that the right arm is unilaterally raised, the control strategy may be that the wind speed increases by 50 revolutions per minute (r / min) every time the posture is maintained for 1 second.

[0127] If the second control posture information is that the right arm is pressed down unilaterally, the control strategy may be that the wind speed decreases by 50r / min every time the posture is maintained for 1 second.

[0128] Optionally, the third control posture information may be that the two arms are raised upward or pressed downward in opposite directions. Accordingly, the corresponding control strategy is mainly used to adjust the execution angle of the vertical swing leaf assembly. The embodiment of the present invention does not specifically limit the adjustment method.

[0129] For example, when the third control posture information is the left hand raised and the right hand pressed down, the control strategy may be that for every second that the posture is maintained, the execution angle of the vertical swing leaf assembly swings horizontally to the right by 5°.

[0130] If the third control posture information is that the right hand is raised and the left hand is pressed down, the control strategy may be that for every second that the posture is maintained, the execution angle of the vertical swing leaf assembly swings horizontally to the left by 5°.

[0131] Optionally, the fourth control posture information may be that both arms are raised upward or pressed downward. Accordingly, the corresponding control strategy is mainly used to adjust the execution angle of the swing leaf assembly. The embodiment of the present invention does not specifically limit the adjustment method.

[0132] For example, when the fourth control posture information is both hands raised, the control strategy may be that when the posture is maintained for 1 second, the execution angle of the lateral leaf assembly is swung vertically upward by 5°.

[0133] If the fourth control posture information is when both hands are pressed down, the control strategy may be that for every second that the posture is maintained, the execution angle of the lateral leaf assembly is swung vertically downward by 5°.

[0134] The embodiment of the present invention uses the first control posture information, the second control posture information, the third control posture information and the fourth control posture information stored in the posture library to map to the control strategies for adjusting the outlet air temperature, the outlet air speed, the execution angle of the vertical swing blade assembly and the execution angle of the horizontal swing blade assembly, respectively. When the user is engaged in sports activities in a large public space, the working state of the air conditioner is adjusted according to the posture change in the awakened posture control mode, without the need for the user to manually set the parameter adjustment, thereby reducing the control delay and improving the control accuracy of the air conditioner.

[0135] 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 the vibration period.

[0136] The target sampling point is a peak sampling point and / or a trough sampling point within the sampling period.

[0137] Specifically, in step 101, the radar-based air conditioning fresh air control device averages the vibration sampling signal that periodically fluctuates 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:

[0138]

[0139]

[0140] Where T is the average sampling period, A is the average sampling amplitude. n is the number of vibration periods contained 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 jIt 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.

[0141] The first vibration wave is generated based on the average sampling period and the average sampling amplitude.

[0142] Specifically, the radar-based air conditioning fresh air control device uses the average sampling period T and the average sampling amplitude A as the new period and amplitude, respectively, to reconstruct the first vibration wave after stabilizing the vibration condition of the indoor unit.

[0143] 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.

[0144] 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

[0145] Here, k is a positive integer greater than 2.

[0146] 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.

[0147]

[0148] 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.

[0149] Then, the radar-based air conditioning fresh air control device 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.

[0150] For example, Figure 3 FIG. 2 is a flow chart of the radar-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 a radar-based air conditioning control method:

[0151] (1) After the air conditioner is activated, the vibration sensor is used to sample the vibration of the indoor unit to obtain a first vibration wave.

[0152] (2) Control the vibration generator to output a second vibration wave to eliminate the vibration transmitted to the radar module, and continue to use the radar after the vibration elimination to capture the human body trajectory and integrate it into the first posture information.

[0153] (3) If the first posture information at this time is a preset wake-up posture (i.e., a human body standing with both hands flat), and it lasts for more than 1 second, the posture control mode is activated.

[0154] (4) In the attitude control mode, the second attitude information of the human body captured by the millimeter-wave radar after vibration cancellation is matched with the attitude library stored in the computer board. If the pairing is successful, execute step (5) and control the air conditioner to respond with three "beeps". Otherwise, jump to step (6).

[0155] (5) According to the control posture information matched by the second posture information in the posture library, the air conditioner is controlled to execute the control strategy pre-set with the control posture information, and after the adjustment of the current default working mode is completed, the air conditioner is controlled to respond with a "beep" sound.

[0156] (6) If the gesture library cannot be paired successfully within 10 seconds, the gesture control mode will be exited.

[0157] 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.

[0158] Figure 4 FIG. 1 is a schematic diagram of the structure of the radar-based air conditioning control device provided by the present invention. Figure 4 As shown, the device includes a radar stabilization module 410, an attitude control starting module 420 and an attitude control implementation module 430, wherein:

[0159] The radar stabilization module 410 is used to determine the first vibration wave based on the vibration sampling signal collected by the vibration sensor from the indoor unit of the air conditioner.

[0160] The posture control start module 420 is used to start the posture control mode when, during the process of controlling the vibration generator to output the second vibration wave, the radar module determines that at least one individual's first posture information is a preset wake-up posture, and the duration of the wake-up posture reaches a preset threshold.

[0161] The posture control implementation module 430 is used to match the control strategy corresponding to the second posture information of the first target individual according to the posture library, so that the air conditioner can adjust the current default working mode according to the control strategy.

[0162] Among them, the first target individual is any one of the individuals in a wake-up posture in a large public place; the second posture information is determined by the first target individual according to the human feature information collected by the radar module from the first target individual after determining that the posture control mode has been started; the control strategy is used to adjust the control parameters in the default working mode, and the control parameters include at least one of the air outlet temperature, the air outlet speed and the swing wind mode; 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; the vibration sampling signal is a vibration signal generated by the operation of the fan of the air-conditioning indoor unit during the sampling period; the vibration sensor, the radar module and the vibration generator are all arranged in the air-conditioning indoor unit, the vibration sensor is used to sense the vibration of the air-conditioning indoor unit, and the vibration generator is used to eliminate the vibration of the radar module driven by the air-conditioning indoor unit.

[0163] Specifically, the radar stabilization module 410, the attitude control starting module 420 and the attitude control implementation module 430 are electrically connected in sequence.

[0164] After receiving and responding to the activation instruction, the radar stabilization module 410 controls the fan of the air-conditioning indoor unit to run at the speed in this mode, and controls the compressor of the air-conditioning outdoor unit to run at the power in this mode.

[0165] Since the operation of the fan will cause its own vibration to propagate to the air-conditioning indoor unit and its internal components, the radar stabilization module 410 periodically senses the vibration of the air-conditioning indoor unit through a vibration sensor, and fits a first vibration wave used to characterize the degree of vibration of the air conditioner based on the vibration sampling signal collected within a sampling period.

[0166] 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.

[0167] The attitude control start module 420 retains the period and amplitude of the first vibration wave obtained by the radar stabilization module 410, 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 to emit a vibration wave with the second vibration wave to continuously eliminate the vibration of the radar module.

[0168] While the vibration generator is continuously eliminating vibrations of the radar module, the radar-based air-conditioning control device uses the radar module after the vibration elimination to collect real-time human feature information from each individual in the large public space where the air conditioner is located, and analyzes the human morphological features contained therein. If the first posture information obtained by the analysis of any individual matches the pre-set wake-up posture, and the duration for which the individual maintains the wake-up posture reaches a preset threshold, it means that the individual's current behavioral intention is not to perform some specific movements in a public place with large space characteristics (such as a yoga studio, gymnasium, etc.), but to activate the posture control mode of the air conditioner by actively performing a wake-up action.

[0169] If the first posture information of any individual does not match the preset wake-up posture, or the duration for which the individual maintains the wake-up posture does not reach the preset threshold, it means that the individual's current behavioral intention is only to perform some specific movement movements in a public place with large space characteristics (such as a yoga studio, gymnasium, etc.), and the posture control mode will not be triggered.

[0170] After determining that the posture control mode has been turned on, the posture control implementation module 430 uses the vibration-damped radar module in this mode to continue posture monitoring of the first target individual that starts the posture control mode, and uses the second posture information collected from it as retrieval information to perform query and match in the posture library. The results are divided into two types: successful matching and failed matching.

[0171] A successful match means that the posture displayed by the individual in the posture control mode matches the information stored in the locally stored posture library, which means that the individual's current posture can trigger the control strategy preset in this mode. Therefore, the control strategy corresponding to the second posture information can be extracted according to the mapping relationship stored in the posture library.

[0172] Matching failure means that the posture displayed by the individual in the posture control mode does not match any information in the locally stored posture library, which means that the individual's current posture can trigger the control strategy preset in this mode, and the control strategy needs to be triggered with the correct posture.

[0173] Optionally, the attitude control implementation module 430 is further used to turn off the attitude control mode when it is determined by using the radar module after the second vibration wave is damped that the third attitude information of each individual does not match the attitude library.

[0174] Among them, the third posture information is determined in the posture control mode according to the human body feature information collected by the radar module for each individual within a preset time period; the radar module after using the second vibration wave to eliminate the vibration is offset by the second vibration wave that has a phase difference of half a cycle with the first vibration wave, thereby offsetting the vibration of the radar module caused by the first vibration wave under the propagation of the air-conditioning indoor unit.

[0175] Optionally, the device further comprises a posture library setting mode starting module, a posture library setting module and a notice module, wherein:

[0176] The posture library setting mode starting module is used to receive and respond to the setting instruction issued by the second target individual to start the posture library setting mode.

[0177] The posture library setting module is used to analyze the human feature information of the second target individual monitored by the radar module after the second vibration wave is eliminated during the action collection period, and store the analyzed control posture information corresponding to the target control strategy into the posture library.

[0178] The notification module is used to control the air conditioner to give an audible and visual prompt that the posture library setting mode has been completed according to the notification signal when it is determined that the control posture information corresponding to all control strategies has been stored in the library.

[0179] Among them, the second target individual is any one of the individuals in a large public space; the control strategy corresponds to the action collection period one by one, and the target control strategy is any one of the control strategies; the radar module after the second vibration wave is damped is used to offset the vibration of the radar module caused by the first vibration wave under the propagation of the air-conditioning indoor unit by the second vibration wave having a phase difference of half a cycle with the first vibration wave.

[0180] Optionally, the posture library setting module includes a key point recognition unit and a posture grouping unit, wherein:

[0181] The key point identification unit is used to determine the key point position information based on the human feature information of the second target individual monitored by the radar module after the second vibration wave is de-energized.

[0182] The posture grouping unit is used to perform coordinate system conversion and standardization operations on the key point position information to obtain control posture information corresponding to the target control strategy.

[0183] Optionally, the gesture library includes first control gesture information, second control gesture information, third control gesture information and fourth control gesture information;

[0184] The first control posture information is that the left arm is raised or pressed down unilaterally to increase or decrease the air outlet temperature;

[0185] The second control posture information is that the right arm is raised or pressed down unilaterally to increase or decrease the wind speed;

[0186] The third control posture information is that the two arms are raised up or pressed down in opposite directions to adjust the execution angle of the vertical swing leaf assembly;

[0187] The fourth control posture information is that both arms are raised upward or pressed downward to adjust the execution angle of the swing leaf assembly.

[0188] Optionally, the radar stabilization module 410 includes a stabilization calculation unit and a linear fitting unit, wherein:

[0189] The stability maintenance calculation unit is used to obtain an average sampling period according to a plurality of vibration periods included in the vibration sampling signal, and to obtain an average sampling amplitude according to the vibration amplitude corresponding to the target sampling point in the vibration period.

[0190] A linear fitting unit is used to generate the first vibration wave based on the average sampling period and the average sampling amplitude.

[0191] The target sampling points include peak sampling points and trough sampling points within the sampling period.

[0192] Optionally, 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

[0193] Here, k is a positive integer greater than 2.

[0194] The radar-based air conditioning fresh air control device provided in an embodiment of the present invention is used to execute the above-mentioned radar-based air conditioning fresh air control method of the present invention. Its implementation method is consistent with the implementation method of the radar-based air conditioning fresh air control method provided by the present invention, and can achieve the same beneficial effects, which will not be repeated here.

[0195] 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 propagated by the indoor unit of the air conditioner. When the radar module after the vibration elimination detects that the first posture information of at least one individual shows a trend of continuously maintaining the awakening posture, the posture control mode is activated, and the radar module continues to capture the second posture information displayed by the individual activating the mode. When the control condition is triggered, the original working mode is adjusted using the control strategy corresponding to the second posture information. 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 to enable stable imaging during air conditioner radar observation, so that when the user is engaged in sports activities in a large public space, the working state of the air conditioner can be adjusted according to the posture change in the awakened posture control mode, without the need for the user to manually set the parameter adjustment, while reducing the control delay and improving the perception accuracy and control accuracy of the air conditioner, and taking into account the user's sports experience and the use experience of the air conditioner.

[0196] Figure 5 Schematic diagram of the structure of the air conditioner provided by the present invention. Figure 5 As shown, the air conditioner provided by the embodiment of the present invention includes an air conditioner indoor unit 510 and an air conditioner outdoor unit 520 .

[0197] The air-conditioning indoor unit 510 includes an air-conditioning controller 511 and a vibration reduction device 512 that are communicatively connected, and also includes a memory and a program or instruction stored in the memory and executable on the air-conditioning controller 511. When the program or instruction is executed by the air-conditioning controller 511, the radar-based air-conditioning control method as described in any of the above items is executed.

[0198] The vibration elimination device 512 includes a radar module 512 - 1 , a vibration generator 512 - 2 and a vibration sensor 512 - 3 which are respectively connected to the air conditioning controller 511 for communication.

[0199] The vibration sensor 512 - 3 is used to sense the vibration of the air conditioner indoor unit. The vibration generator 512 - 2 is used to eliminate the vibration of the radar module 512 - 1 driven by the air conditioner indoor unit 510 .

[0200] Among them, the radar module 512-1 is a millimeter wave radar.

[0201] Specifically, the fresh air air conditioner is provided with an indoor unit 510, an outdoor unit 520 and a fresh air system 530. The indoor unit 510 and the outdoor unit 520 are connected by a refrigerant pipeline, and the fresh air system 530 independently uses an air duct for circulating fresh air.

[0202] Among them, an air-conditioning controller 511 and a vibration reduction device 512 that are communicatively connected are provided in the air-conditioning indoor unit 510. The air-conditioning controller 511 is integrated in the control chip of the air-conditioning system, so that when executing the radar-based air-conditioning control method, the vibration sensor 512-3 is controlled to periodically sense the vibration occurring in the air-conditioning indoor unit 510, and a first vibration wave for characterizing the vibration degree of the air-conditioning is fitted according to the vibration sampling signal collected within a sampling period.

[0203] 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 to emit the second vibration wave to continuously eliminate the vibration of the radar module 512-1.

[0204] While the vibration generator is continuously silencing the radar module 512-3, the air conditioning controller 511 analyzes the human morphological characteristics contained in the human feature information collected in real time from each individual in the large public space where the air conditioner is located through the radar module 512-3 after the vibration is eliminated. If the first posture information obtained by the analysis of any individual matches the pre-set wake-up posture, and the duration for which the individual maintains the wake-up posture reaches a preset threshold, it means that the individual's current behavioral intention is not to perform some specific movements in a public place with large space characteristics (such as a yoga studio, gymnasium, etc.), but to activate the posture control mode of the air conditioner by actively performing a wake-up action.

[0205] If the first posture information of any individual does not match the preset wake-up posture, or the duration for which the individual maintains the wake-up posture does not reach the preset threshold, it means that the individual's current behavioral intention is only to perform some specific movement movements in a public place with large space characteristics (such as a yoga studio, gymnasium, etc.), and the posture control mode will not be triggered.

[0206] After determining that the attitude control mode has been turned on, the air conditioning controller 511 uses the vibration-damped radar module 512-1 in this mode to continue to monitor the attitude of the first target individual that starts the attitude control mode, and uses the second attitude information collected from it as retrieval information to perform query and match in the attitude library. The results are divided into two types: successful matching and failed matching.

[0207] A successful match means that the posture displayed by the individual in the posture control mode matches the information stored in the locally stored posture library, which means that the individual's current posture can trigger the control strategy preset in this mode. Therefore, the control strategy corresponding to the second posture information can be extracted according to the mapping relationship stored in the posture library.

[0208] Matching failure means that the posture displayed by the individual in the posture control mode does not match any information in the locally stored posture library, which means that the individual's current posture can trigger the control strategy preset in this mode, and the control strategy needs to be triggered with the correct posture.

[0209] 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 propagated by the indoor unit of the air conditioner. When the radar module after the vibration elimination detects that the first posture information of at least one individual shows a trend of continuously maintaining the awakening posture, the posture control mode is activated, and the radar module continues to capture the second posture information displayed by the individual activating the mode. When the control condition is triggered, the original working mode is adjusted using the control strategy corresponding to the second posture information. 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 to enable stable imaging during air conditioner radar observation, so that when the user is engaged in sports activities in a large public space, the working state of the air conditioner can be adjusted according to the posture change in the awakened posture control mode, without the need for the user to manually set the parameter adjustment, while reducing the control delay and improving the perception accuracy and control accuracy of the air conditioner, and taking into account the user's sports experience and the use experience of the air conditioner.

[0210] In addition, the logic instructions in the memory can be implemented in the form of software functional units and can be stored in a computer-readable storage medium when sold or used as an independent product. Based on this understanding, the technical solution of the present invention can be essentially or partly embodied in the form of a software product that contributes to the prior art. The computer software product is stored in a storage medium and includes several instructions for a computer device (which can be a personal computer, a server, or a network device, etc.) to perform all or part of the steps of the method described in each embodiment of the present invention. The aforementioned storage medium includes: U disk, mobile hard disk, read-only memory (ROM, Read-Only Memory), random access memory (RAM, Random Access Memory), disk or optical disk, etc. Various media that can store program codes.

[0211] On the other hand, the present invention also provides a computer program product, which includes a computer program.
