Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioning equipment, and in particular to an air conditioner control method and device based on radar and an air conditioner. BACKGROUND

[0002] With the continuous improvement of people's living standards, air conditioners have become common household appliances. Air conditioners are widely used in homes, office buildings, supermarkets, stadiums and other places. Existing air conditioners are usually controlled according to user-set parameters. For ordinary household air conditioners, the air conditioner runs according to the user-set temperature and wind speed, which may lead to inconsistencies with the current working conditions. For commercial air conditioners, they usually work in a unified control mode. The number of personnel in the application site may be different at different times, and a human perception device is usually additionally set up for monitoring. In existing human-sensing-based air conditioner intelligent control schemes, only AI technology based on face recognition can achieve accurate personnel type judgment. However, such a scheme not only requires a high-definition camera, but also needs to run a face recognition algorithm, which significantly increases the manufacturing cost of the air conditioner, leading 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 sign data such as respiration rate, heart rate and body movement of personnel by processing and analyzing received radar echoes with human features. Millimeter wave radar is a radar that works in the millimeter wave (wavelength 1-10 mm, frequency 30-300 GHz) band for detection. It is commonly used in air conditioners to achieve functions such as human presence to start the machine, human absence to shut down the machine, and windless feeling. However, the vibration generated by the air conditioner during operation can affect the data collection of the radar and even cause imaging blur. The longitudinal vibration of the longitudinal wave can affect the vertical data collection of the target. Similarly, the transverse wave can affect the transverse data collection. If the amplitude is large, it can even image a stationary target as a moving target, which seriously affects the radar sensing accuracy and may cause errors in the current working condition judgment, leading to energy mismatch. Therefore, the control accuracy of existing air conditioners is poor, especially for users in public places such as office buildings, supermarkets and stadiums. SUMMARY

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0053] It should be understood that the terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the present application, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include the plural forms.

[0054] The terms "include" and "contain" indicate the presence of the described features, whole, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, whole, steps, operations, elements, components and / or sets thereof.

[0055] Figure 1 is one of the flow diagrams of the radar-based air conditioner control method provided by the present application. As shown in Figure 1 The radar-based air conditioner control method provided by the embodiments of the present application comprises: step 101, determining a first vibration wave based on a vibration sampling signal collected by a vibration sensor on an indoor unit of an air conditioner.

[0056] The vibration sampling signal is a vibration signal generated by the indoor unit of the air conditioner due to the operation of the fan in a sampling period. The vibration sensor, the radar module and the vibration generator are all arranged in the indoor unit of the air conditioner. The vibration sensor is used to sense the vibration condition of the indoor unit of the air conditioner, and the vibration generator is used to eliminate the vibration of the radar module driven by the indoor unit of the air conditioner.

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

[0058] The application scenario of the radar-based air conditioner control method provided by the embodiment of the application is that, after a user activates the air conditioner, the vibration sensor is used to perceive the vibration waveform change of the air conditioner generated at different air speeds and modes, and the vibration generator is used to emit an opposite waveform to offset the vibration of the radar module caused by the air conditioner, and if the action posture of an individual monitored by the radar module after vibration offset is a preset wake-up posture, the default air supply mode is adjusted to the air supply mode corresponding to the action posture monitored by the radar in the posture control mode after the posture control mode is started.

[0059] The radar module periodically collects all individuals in the room for monitoring at a specified time interval, and sends the contour information of each individual to the radar-based air conditioner control device. The working period of the radar module is not limited in the embodiment of the application.

[0060] Optionally, the radar module can collect data at a default working period.

[0061] Optionally, the user can issue a period change instruction, and the radar module receives and responds to the instruction to change the working period to the period indicated by the instruction for collection.

[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 operates at the default air speed in the mode, and the outdoor unit operates at the default frequency in the mode.

[0063] Optionally, the user can transmit the activation instruction through the wireless communication between the control device and the air conditioning system by using the control device to control the device, so that the air conditioning system initializes the working mode and starts the radar module.

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

[0065] Specifically, in step 101, the radar-based air conditioner control device receives and responds to the activation instruction, controls the fan of the air conditioner indoor unit to operate at the rotating speed in the mode, and controls the compressor of the air conditioner outdoor unit to operate at the power in the mode.

[0066] Since the fan actuation causes the vibration generated by itself to propagate to the air conditioner indoor unit and its internal devices, the radar-based air conditioner control device periodically perceives the vibration generated by the air conditioner indoor unit through the vibration sensor, and according to the vibration sampling signal collected in a sampling period, a first vibration wave for representing the vibration degree of the air conditioner is fitted.

[0067] The sampling period is a working period of the vibration sensor for sensing, and is at least an integer multiple of the vibration period of the air conditioner, and the embodiment of the present application does not make specific limitation.

[0068] In step 102, in the process of controlling the vibration generator to output the second vibration wave, if it is determined by the radar module that the first posture information of at least one individual is the preset wake-up posture, and the duration of the wake-up posture reaches the 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 conditioner control device retains the period and amplitude of the first vibration wave obtained in step 101, and delays the phase by half a period to obtain a second vibration wave with a waveform opposite to that of the first vibration wave, and then controls the vibration generator to emit a vibration wave with the second vibration wave to continuously damp the radar module.

[0071] In the process of continuously damping the radar module by the vibration generator, the radar-based air conditioner control device analyzes the human body shape features contained in the human body feature information of each individual in the large space public place where the air conditioner is located, which is collected in real time by the radar module after damping, and if the first posture information of any individual matches the pre-set wake-up posture, and the duration of the individual maintaining the wake-up posture reaches the preset threshold, it means that the current behavior intention of the individual is not to make some specific movement actions in the public place with large space characteristics (such as yoga studio, gymnasium, etc.), but to actively perform the wake-up action to activate the posture control mode of the air conditioner.

[0072] If the first posture information of any individual does not match the pre-set wake-up posture, or the duration of the individual maintaining the wake-up posture does not reach the preset threshold, it means that the current behavior intention of the individual is only to make some specific movement actions in the public place with large space characteristics (such as yoga studio, gymnasium, etc.), and the posture control mode will not be triggered.

[0073] The type and number of radar sensing devices in the radar module are not specifically limited in the embodiment of the present application.

[0074] For example, the radar module can 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 is ±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 there is no privacy problem, no light influence, and the response speed is also faster.

[0076] Therefore, the radar-based air conditioner control device analyzes the behavior state of the user individual based on the individual contour information collected by the millimeter wave radar in real time.

[0077] Exemplarily, the radar module can include multiple types of sensing elements such as millimeter wave radar, laser radar, infrared sensor, etc., and the radar-based air conditioner control device integrates the contour information collected by each sensing element to comprehensively depict the real-time posture of the individual.

[0078] Step 103, according to the posture library, the control strategy corresponding to the second posture information of the first target individual is matched, so that the air conditioner adjusts the current default working mode according to the control strategy.

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

[0080] It should be noted that the first target individual refers to an individual who continuously maintains a wake-up 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 mapping relationship that records that the radar module executes different control strategies when monitoring that the individual is in various postures (or posture trajectories) after the radar-based air conditioner control device completes the setting of the control trigger condition of the posture control mode.

[0082] Among them, the control strategy is composed of the adjustment amount of different control parameters, and the control parameters involved include but are not limited to the outflow temperature, the outflow air speed and the swing air mode.

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

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

[0085] The swing mode refers to that the swing leaf assembly of the air conditioner is swung by the motor to change the wind direction and realize swing, and the swing speed and swing range of the swing leaf assembly can be adjusted on the basis of the default working mode.

[0086] Specifically, in step 103, the radar-based air conditioner control device continues to monitor the posture of the first target individual that starts the posture control mode in this mode after determining that the posture control mode is started, and takes the second posture information collected therefrom as search information to query and match in the posture library, and the result is divided into two kinds: matching success and matching failure.

[0087] The matching success is that the posture of the individual in the posture control mode can match the information stored in the posture library, which means that the current posture of the individual can trigger the control strategy preset in the mode, so the control strategy corresponding to the second posture information can be extracted according to the mapping relationship stored in the posture library.

[0088] The matching failure is that the posture of the individual in the posture control mode cannot match any information in the posture library, which means that the current posture of the individual can trigger the control strategy preset in the mode, and the control strategy needs to be triggered by the correct posture.

[0089] The embodiment of the application transmits the second vibration wave opposite to the actual first vibration wave by the vibration generator to cancel the vibration transmitted by the indoor unit of the air conditioner, and when the first posture information of at least one individual monitored by the radar module after the vibration cancellation shows a trend of continuously maintaining the wake-up posture, the posture control mode is activated, and the second posture information exhibited by the individual activating the mode is continuously captured by the radar module, and when the control condition is triggered, the original working mode is adjusted by 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 can be superimposed and damped to stabilize the imaging when the air conditioner radar observes, so that the user can adjust the working state of the air conditioner according to the posture change in the wake-up posture control mode when engaging in sports activities in a large space public place, without manually setting the parameter adjustment, reducing the control delay, improving the perception accuracy and control accuracy of the air conditioner, and balancing the user's sports experience and the use experience of the air conditioner.

[0090] On the basis of any of the above embodiments, after the start posture control mode, further comprising: in the case that the third posture information of each individual determined by the radar module after the second vibration wave is damped does not match the posture library, closing the posture control mode.

[0091] Wherein, the third posture information is determined according to the human feature information collected by the radar module within a preset time length in the posture control mode; the radar module after the second vibration wave is damped is through the second vibration wave with a phase difference of half a cycle from the first vibration wave to offset the vibration of the radar module under the propagation of the air conditioner indoor unit in the first vibration wave.

[0092] It should be noted that, Figure 2 is the principle diagram of the vibration damping of the radar module provided by the application. As Figure 2 indicated, 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 damp the radar module is given:

[0093] During the operation of the air conditioner indoor unit, the vibration waveform generated is similar to a harmonic wave, but the amplitude of each cycle is not exactly the same, and there is a slight gap, and accordingly, 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 from the first vibration wave, its waveform is completely opposite to the first vibration wave, i.e. (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 generated by the air conditioner indoor unit can be offset.

[0094] Specifically, in step 102, the radar-based air conditioner control device can further use the damped radar module to continuously monitor the posture of all individuals in the posture control mode after determining that the posture control mode has been opened. When it is determined that the third posture information collected within a preset time length by the individual who starts the posture control mode and the remaining individuals in the space does not match the posture library, the posture control mode is closed, and the radar module is operated in a low-energy-consumption state.

[0095] The embodiment of the application continues to use the damped radar module to monitor the posture of individuals in the posture control mode, and when the third posture information captured by each individual fails to trigger the control condition of the posture library, the posture control mode is closed, and the air conditioner remains in the original working mode. When the user engages in sports activities in a large public space and the posture control mode is awakened without matching the posture change and the preset control condition, the posture control mode automatically enters a dormant state, reducing unnecessary energy consumption.

[0096] On the basis of any of the above embodiments, the method further comprises: receiving and responding to a setting instruction issued by the second target individual, starting a gesture library setting mode.

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

[0098] It should be noted that the second target individual is any individual in the large space public place, and the subjective action intention of the individual is to perform action recording and strategy formulation on the gesture library corresponding to the gesture control mode.

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

[0100] The human feature information monitored by the radar module after vibration cancellation using the second vibration wave in the action collection period is analyzed, and the control gesture information corresponding to the target control strategy obtained by analysis is stored in the gesture library.

[0101] The control strategy corresponds to the action collection period one-to-one, and the target control strategy is any of the control strategies. The radar module after vibration cancellation using the second vibration wave cancels the vibration of the radar module caused by the first vibration wave due to the propagation of the air conditioner indoor unit.

[0102] It should be noted that in the gesture library setting mode, an action collection period is set for the formulation process of each control strategy to capture the gesture or gesture trajectory of the corresponding control strategy in the period.

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

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

[0105] Specifically, when it is determined that all control gesture information corresponding to the control strategies has been stored in the gesture library, the radar-based air conditioner control device controls the air conditioner to output an announcement signal.

[0106] The announcement signal can be one or more types of sound signal, light signal or vibration signal, and the type and signal composition method of the embodiment of the present application are not limited. The announcement signal is used to convey information to the user in the space that the posture library setting mode has been completed.

[0107] The embodiment of the present application receives and responds to the setting instruction, and sequentially triggers the collection and storage of the control posture information of the corresponding control strategy in each action collection period until the entry of the trigger posture of all control strategies, so as to complete the setting of the posture library before starting the posture control mode, so as to adaptively adjust the working mode of the air conditioner according to the posture trigger in the subsequent process, and intelligently control the air conditioner.

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

[0109] Specifically, the radar-based air conditioner control device detects the human feature information monitored by the radar module after the second vibration wave, locates and identifies the human key points such as joints, facial features, etc., and the key point position information corresponding to each key point.

[0110] The key point position information is subjected to coordinate system conversion and standardization operation to obtain the control posture information corresponding to the target control strategy.

[0111] Specifically, the radar-based air conditioner control device performs coordinate system conversion and standardization operation on the key point position information belonging to one individual, and connects the joints in sequence to obtain the posture exhibited by the human when setting the target control strategy, and outputs the posture as the control posture information.

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

[0113] The human feature information of the second target individual monitored by the damped radar module is used to globally extract the key point position information of the human body, and the key points are mapped to different human individuals to obtain the input control posture information corresponding to the target control strategy set by the individual. The human-computer interaction scene can be realized, and the air supply control of the user in the movement process is more convenient, and the user experience is improved.

[0114] On the basis of any of the above embodiments, the posture library includes first control posture information, second control posture information, third control posture information, and fourth control posture information.

[0115] The first control posture information is unilateral up or down of the left arm to raise or lower the air outlet temperature.

[0116] The second control posture information is unilateral up or down of the right arm to raise or lower the air outlet speed.

[0117] The third control posture information is bilateral reverse up or down to adjust the execution angle of the vertical swing leaf assembly.

[0118] The fourth control posture information is bilateral same direction up or down to adjust the execution angle of the horizontal swing leaf assembly.

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

[0120] The embodiment of the present application does not make specific limitation on the form of different trigger postures entered by the user in the posture library setting mode for different control strategies.

[0121] Exemplarily, taking the posture of standing and spreading both hands as an example, a set of control posture information pre-set for the posture library and the corresponding control strategy are given:

[0122] Optionally, the first control posture information can be unilateral up or down of the left arm, and the corresponding control strategy is mainly used for adjusting the air outlet temperature, and the adjusting mode is not limited by the embodiment of the present application.

[0123] For example, when the first control posture information is unilateral up of the left arm, the control strategy can be that the air outlet temperature is increased by 1℃ for every 1 second of maintaining the posture.

[0124] If the first control posture information is unilateral down of the left arm, the control strategy can be that the air outlet temperature is decreased by 1℃ for every 1 second of maintaining the posture.

[0125] Optionally, the second control posture information can be unilateral up or down of the right arm, and the corresponding control strategy is mainly used for adjusting the air outlet speed, and the adjusting mode is not limited by the embodiment of the present application.

[0126] For example, when the second control posture information is unilateral up of the right arm, the control strategy can be that the air outlet speed is increased by 50 revolutions per minute (r / min) for every 1 second of maintaining the posture.

[0127] If the second control posture information is unilateral down of the right arm, the control strategy can be that the air outlet speed is decreased by 50 r / min for every 1 second of maintaining the posture.

[0128] Optionally, the third control posture information can be bilateral reverse up or down, and the corresponding control strategy is mainly used for adjusting the execution angle of the vertical swing leaf assembly, and the adjusting mode is not limited by the embodiment of the present application.

[0129] For example, when the third control posture information is up of the left hand and down of the right hand, the control strategy can be that the execution angle of the vertical swing leaf assembly is swung horizontally to the right by 5° for every 1 second of maintaining the posture.

[0130] If the third control posture information is up of the right hand and down of the left hand, the control strategy can be that the execution angle of the vertical swing leaf assembly is swung horizontally to the left by 5° for every 1 second of maintaining the posture.

[0131] Optionally, the fourth control gesture information can be that the two arms are upwardly raised or downwardly pressed in the same direction, and correspondingly, the control strategy corresponding to the fourth control gesture information is mainly used for adjusting the execution angle of the yaw vane assembly, and the adjusting mode is not limited in the embodiment of the present application.

[0132] For example, when the fourth control gesture information is that the two hands are upwardly raised, the control strategy can be that the execution angle of the yaw vane assembly is vertically upwardly swung by 5° for each 1 second that the gesture is maintained.

[0133] If the fourth control gesture information is that the two hands are downwardly pressed, the control strategy can be that the execution angle of the yaw vane assembly is vertically downwardly swung by 5° for each 1 second that the gesture is maintained.

[0134] The first control gesture information, the second control gesture information, the third control gesture information and the fourth control gesture information stored in the gesture library are respectively mapped to the control strategies for adjusting the outflow temperature, the outflow air speed, the execution angle of the pitch vane assembly and the execution angle of the yaw vane assembly in the embodiment of the present application. 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 gesture change in the awakened gesture control mode, without the user manually setting the parameter adjustment, so that the control time delay is reduced and the control precision of the air conditioner is improved.

[0135] On the basis of any of the above embodiments, the first vibration wave is determined based on the vibration sampling signal collected by the vibration sensor of the air conditioner indoor unit, and includes: obtaining an average sampling period according to a plurality of vibration periods contained in the vibration sampling signal, and obtaining an average sampling amplitude according to the vibration amplitude corresponding to a target sampling point in the vibration period.

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

[0137] Specifically, in step 101, the radar-based air conditioner fresh air control device performs mean value processing on the vibration sampling signal that periodically and variably changes at a specific target sampling point in a sampling period, to obtain an average sampling period and an average sampling amplitude that can represent the overall vibration level, and the calculation formula is as follows:

[0138]

[0139]

[0140] Wherein, 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 period in the sampling period. For any vibration period, if the target sampling point is a wave peak sampling point and a wave trough sampling point in the vibration period, then in the i-th vibration period, A jmay be the amplitude peak value corresponding to the peak sampling point in the vibration period, at this time j=2i-1. j may be the amplitude valley value corresponding to the valley sampling point in the vibration period, at this time j=2i.

[0141] generate the first vibration wave based on the average sampling period and the average sampling amplitude.

[0142] Specifically, the radar-based air conditioner fresh air control device takes the average sampling period T and the average sampling amplitude A as new periods and amplitudes respectively to reconstruct the first vibration wave after maintaining the vibration of the indoor unit.

[0143] The embodiment of the present application reconstructs the first vibration wave for representing the stable vibration level by using the average sampling period and the average sampling amplitude obtained after the mean value processing of the multiple vibration periods contained in the vibration sampling signal and the floating change of the vibration amplitude at the target sampling point in each vibration period. The vibration wave emitted by the air conditioner during its operation can be maintained to provide reasonable reference value for subsequent superposition shock absorption, and the radar sensing accuracy of the air conditioner is greatly improved.

[0144] On the basis of any of the above embodiments, if the target sampling point is other than the peak sampling point and the valley sampling point in the vibration period, the value of the target sampling point in the time domain includes and

[0145] wherein 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 valley sampling point in the vibration period that is, in any vibration period, the absolute value of the amplitude of the sampling point there are three sampling points with the same absolute value of amplitude as the sampling point and .

[0147]

[0148] wherein, is the average sampling amplitude at the sampling point , and are the amplitudes corresponding to the sampling points with the same absolute value of amplitude as the sampling point in the mth vibration period.

[0149] Then, the radar-based air conditioner fresh air control device adopts the average sampling amplitude A obtained by the peak and valley mean value processing on the basis of other sampling points averaging the mean sample amplitude deconstructing the first vibration wave.

[0150] Exemplarily, Figure 3 is the second flowchart of the radar-based air conditioner control method provided by the present application. Figure 3 As shown in the figure, the present application provides a specific embodiment of a radar-based air conditioner control method:

[0151] (1) After activating the air conditioner, the vibration sensor is used to sample the vibration generated by the indoor unit, obtaining the first vibration wave.

[0152] (2) The vibration generator is controlled to output the second vibration wave to dissipate the vibration propagated to the radar module, and the radar after vibration dissipation is used to capture the human body posture trajectory, which is integrated into the first posture information.

[0153] (3) If the first posture information at this time is the preset wake-up posture (i.e. the human body stands with both hands flat), and the duration exceeds 1 second, the posture control mode is started.

[0154] (4) In the posture control mode, the second posture information captured by the vibration-dissipated millimeter-wave radar is matched with the posture library stored in the computer board. If the matching is successful, step (5) is executed while the air conditioner is controlled to respond with a "drop" sound. Otherwise, go 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 for the control posture information, complete the adjustment of the current default working mode, and then control the air conditioner to respond with a "drop" sound.

[0156] (6) If the matching with the posture library fails within 10 seconds, the posture control mode is exited.

[0157] The present application reconstructs the first vibration wave based on the average sampling amplitude obtained by peak-to-valley averaging and the average sampling amplitude obtained by averaging other sampling points. It can exclude the interference of extreme values during the process of stabilizing the vibration wave emitted by the air conditioner itself, and improve the linear fitting precision.

[0158] Figure 4 is a structural diagram of the radar-based air conditioner control device provided by the present application. Based on any of the above embodiments, as shown in the figure, Figure 4 the device includes a radar stabilization module 410, a posture control starting module 420, and a posture control implementation module 430, wherein:

[0159] The radar stabilizing module 410 is configured to determine a first vibration wave based on a vibration sampling signal collected by the vibration sensor on the air conditioner indoor unit.

[0160] The posture control starting module 420 is configured to start a posture control mode when it is determined that at least one individual has a first posture information as a preset wake-up posture and the duration of the wake-up posture reaches a preset threshold during the process of controlling the vibration generator to output a second vibration wave.

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

[0162] 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 radar module based on the human feature information collected by the radar module on the first target individual after it is determined 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 at least include one of the outflow temperature, the outflow air speed and the swing air 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 air conditioner indoor unit due to the operation of the fan in a 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 condition of the air conditioner indoor unit, and the vibration generator is used to damp the radar module which is vibrated by the air conditioner indoor unit.

[0163] Specifically, the radar stabilizing module 410, the posture control starting module 420 and the posture control implementation module 430 are sequentially electrically connected.

[0164] After receiving and responding to the activation instruction, the radar stabilizing module 410 controls the fan of the air conditioner indoor unit to operate at a speed in the mode and controls the compressor of the air conditioner outdoor unit to operate at a power in the mode.

[0165] Since the fan actuation will cause the vibration generated by itself to propagate to the air conditioner indoor unit and its internal devices, the radar stabilizing module 410 periodically senses the vibration of the air conditioner indoor unit through the vibration sensor, and fits a first vibration wave for representing the vibration degree of the air conditioner according to the vibration sampling signal collected in a sampling period.

[0166] The sampling period is a working period of the vibration sensor for sensing, and is at least an integer multiple of the air conditioner vibration period, which is not limited in the embodiment of the application.

[0167] The posture control starting module 420 retains the period and amplitude of the first vibration wave obtained by the radar stabilization module 410, delays the phase of the first vibration wave by half a period, obtains a second vibration wave opposite to the first vibration wave in waveform, and controls the vibration generator to emit the second vibration wave to continuously damp the radar module.

[0168] In the process of continuously damping the radar module by the vibration generator, the radar-based air conditioner control device analyzes the human form features contained in the human feature information of each individual in the large-space public place where the air conditioner is located, which is collected by the radar module after damping, and if the first posture information of any individual matches the pre-set wake-up posture and the duration of the individual maintaining the wake-up posture reaches the pre-set threshold, it is indicated that the current behavior intention of the individual is not to make some specific movement actions in the public place with large space characteristics (such as a yoga studio, a gymnasium, etc.), but to activate the posture control mode of the air conditioner by actively performing the wake-up action.

[0169] If the first posture information of any individual does not match the pre-set wake-up posture, or the duration of the individual maintaining the wake-up posture does not reach the pre-set threshold, it is indicated that the current behavior intention of the individual is only to make some specific movement actions in the public place with large space characteristics (such as a yoga studio, a gymnasium, etc.), and the posture control mode is not triggered.

[0170] The posture control implementation module 430, after determining that the posture control mode is started, continues to monitor the posture of the first target individual who starts the posture control mode in this mode by using the radar module after damping, takes the second posture information collected from the individual as retrieval information, and queries and matches the information in the posture library, and the result is divided into two kinds: matching success and matching failure.

[0171] The matching success is a case that the posture exhibited by the individual in the posture control mode can match the information stored in the locally stored posture library, which indicates that the current posture of the individual can trigger the control strategy pre-set in the mode, and therefore the control strategy corresponding to the second posture information can be extracted according to the mapping relationship stored in the posture library.

[0172] The matching failure is a case that the posture exhibited by the individual in the posture control mode cannot match any information in the locally stored posture library, which indicates that the current posture of the individual can trigger the control strategy pre-set in the mode, and the correct posture is required for triggering the control strategy.

[0175] Optionally, the device further comprises a posture library setting mode starting module, a posture library setting module, and a notification module.

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

[0177] The posture library setting module is configured to analyze human feature information monitored by the radar module after the second vibration wave is used to cancel the vibration for the second target individual within a motion collection period, and store control posture information corresponding to a target control strategy obtained by analysis into the posture library.

[0178] The notification module is configured to, in a case where control posture information corresponding to all control strategies is completed and stored, control the air conditioner to give an audible and visual prompt that the posture library setting mode is completed according to a notification signal.

[0179] The second target individual is any one of individuals in a large space public place; the control strategy and the motion collection period are in one-to-one correspondence, and the target control strategy is any one of the control strategies; and the radar module after the second vibration wave is used to cancel the vibration is a second vibration wave that has a phase difference of half a cycle from the first vibration wave and is used to cancel the vibration of the radar module caused by the first vibration wave under the propagation of the air conditioner indoor unit.

[0180] Optionally, the posture library setting module comprises a key point identification unit and a posture grouping unit.

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

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

[0183] Optionally, the posture library comprises first control posture information, second control posture information, third control posture information and fourth control posture information.

[0184] The first control posture information is unilateral up or down of the left arm to raise or lower the air outlet temperature.

[0191] The target sampling point comprises a wave crest sampling point and a wave trough sampling point in the sampling period.

[0192] Optionally, if the target sampling point is other sampling points in the vibration period except the wave crest sampling point and the wave trough sampling point, the value of the target sampling point in the time domain comprises and

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

[0194] The radar-based air conditioner fresh air control device provided by the embodiments of the present application is used to execute the radar-based air conditioner fresh air control method provided by the present application, and the implementation manner is consistent with the implementation manner of the radar-based air conditioner fresh air control method provided by the present application, and the same beneficial effects can be achieved, which will not be repeated here.

[0195] The embodiment of the present application transmits a second vibration wave opposite to the actual first vibration wave through a vibration generator to eliminate the vibration transmitted by the air conditioner indoor unit, when the first posture information of at least one individual monitored by the radar module after vibration elimination shows a trend of continuously maintaining the wake-up posture, the posture control mode is activated, and the second posture information exhibited by the individual activating the mode is continuously captured by the radar module, when the control condition is triggered, the original working mode is adjusted by 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 can be superimposed and eliminated to stabilize the imaging when the air conditioner radar observes, so that the user can adjust the working state of the air conditioner according to the posture change in the wake-up posture control mode when engaging in sports activities in a large space public place, without manually setting the parameter adjustment, reducing the control time delay while improving the perception accuracy and control accuracy of the air conditioner, and can balance the user's sports experience and the use experience of the air conditioner.

[0196] Figure 5 is a structural schematic diagram of the air conditioner provided by the present application. On the basis of any of the above embodiments, as shown in Figure 5 The air conditioner provided by the embodiment of the present application includes an air conditioner indoor unit 510 and an air conditioner outdoor unit 520.

[0197] The air conditioner indoor unit 510 includes an air conditioner controller 511 and a vibration elimination device 512 in communication connection, and further includes a storage and a program or instruction stored on the storage and executable on the air conditioner controller 511, the program or instruction is executed by the air conditioner controller 511 to execute the radar-based air conditioner control method as described in any of the above.

[0198] The vibration elimination device 512 includes a radar module 512-1, a vibration generator 512-2 and a vibration sensor 512-3 in communication connection with the air conditioner controller 511 respectively.

[0199] The vibration sensor 512-3 is used to perceive the vibration condition of the air conditioner indoor unit. The vibration generator 512-2 is used to eliminate the vibration of the radar module 512-1 caused 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 conditioner is provided with an indoor unit 510, an outdoor unit 520 and a fresh air system 530, the air conditioner indoor unit 510 and the air conditioner outdoor unit 520 are communicated through the refrigerant pipeline, and the fresh air system 530 independently enjoys the air duct of circulating fresh air.

[0202] The air conditioner controller 511 is integrated in the control chip of the air conditioning system, so as to control the vibration sensor 512-3 to periodically perceive the vibration of the air conditioner indoor unit 510 when the radar-based air conditioner control method is executed, and fit the first vibration wave for representing the vibration degree of the air conditioner according to the vibration sampling signals collected in a sampling period.

[0203] The air conditioner controller 511 retains the period and amplitude of the obtained first vibration wave, delays the phase of the first vibration wave by half a period, obtains a second vibration wave opposite to the waveform of the first vibration wave, and then controls the vibration generator to emit vibration waves according to the second vibration wave to continuously cancel the vibration of the radar module 512-1.

[0204] In the process of continuously canceling the vibration of the radar module 512-3 by the vibration generator, the air conditioner controller 511 collects the human feature information of each individual in the large space public place where the air conditioner is located in real time through the radar module 512-3 after the vibration is canceled, analyzes the human form features contained in the human feature information, and if the first posture information of any individual matches the pre-set wake-up posture and the individual maintains the wake-up posture for a duration reaching a pre-set threshold, it means that the current behavior intention of the individual is not to make some specific movement actions in the public place with large space characteristics (such as yoga studio, gymnasium, etc.), but to activate the posture control mode of the air conditioner by actively performing the wake-up action.

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

[0206] After the air conditioner controller 511 determines that the posture control mode is started, the radar module 512-1 after the vibration is canceled is used in this mode to preferentially continue to monitor the posture of the first target individual who starts the posture control mode, and the second posture information collected from the individual is used as retrieval information to query and match in the posture library. The result is divided into two kinds: matching success and matching failure.

[0207] Matching success is the case that the posture exhibited by the individual in the posture control mode can match the information stored in the posture library stored locally, which means that the current posture of the individual can trigger the control strategy pre-set in the mode, so the control strategy corresponding to the second posture information can be extracted according to the mapping relationship stored in the posture library.

[0208] The matching failure is a case that the posture exhibited by the individual in the posture control mode cannot match any information in the locally stored posture library, indicating that the current posture of the individual can trigger the control strategy preset by the mode, and the triggering of the control strategy needs to be controlled by the correct posture.

[0209] The embodiment of the present application transmits the second vibration wave opposite to the actual first vibration wave by the vibration generator to cancel the vibration transmitted by the indoor unit of the air conditioner, when the first posture information of at least one individual monitored by the radar module after vibration cancellation shows a trend of continuously maintaining the wake-up posture, the posture control mode is activated, and the second posture information exhibited by the individual activating the mode is captured by the radar module, when the control condition is triggered, the original working mode is adjusted by 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 can be superimposed and damped, so that the air conditioner radar observation can be stable imaging, and the user can adjust the working state of the air conditioner according to the posture change in the wake-up posture control mode when engaging in sports activities in a large space public place, without manually setting the parameter adjustment, reducing the control delay, improving the perception accuracy and control accuracy of the air conditioner, and balancing the user's sports experience and the use experience of the air conditioner.
