Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the description of the embodiments of the present application, it should be understood that the terms "first", "second", and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the embodiments of the present application, "a plurality" means two or more unless specifically defined otherwise.

The following description is presented to enable any person skilled in the art to make and use the application. In the following description, details are set forth for the purpose of explanation. It will be apparent to one of ordinary skill in the art that the present application may be practiced without these specific details. In other instances, well-known processes have not been described in detail so as not to obscure the description of the embodiments of the present application with unnecessary detail. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed in the embodiments herein.

First, before describing the embodiments of the present application, the related contents of the embodiments of the present application with respect to the application context will be described.

As the living standard is gradually improved, the interaction of the air conditioner with the user is gradually increased. The air conditioner is usually provided with a display screen for displaying the set temperature of the user or the current set mode and other operation parameters, but the display strategy of the display screen of the air conditioner is relatively fixed, for example, the light of the display screen of the traditional air conditioner can only be turned on/off manually by the user or turned on/off automatically according to a photosensitive sensor, and after the light of the display screen is turned off, the user needs to manually adjust the light of the display screen again when getting up halfway and wants to watch the display screen. On the other hand, the display screen of the air conditioner can only display one kind of operation parameter, for example, the display screen can only display the set temperature of the user, so the existing air conditioner can not change the displayed content according to the actual demand of the user, the intelligent level is low, and the interactivity is poor.

In recent years, there has appeared an air conditioner in which the brightness of a display screen can be changed by a millimeter wave radar mounted on the air conditioner. However, the air conditioner needs to be additionally provided with a special millimeter wave radar and a receiving module for receiving radar signals, and the content displayed by the display screen cannot be changed, so that the cost is high, and the requirements of users cannot be completely met.

Based on the above defects in the prior art, the embodiments of the present application provide a method for controlling a display screen of an air conditioner, which overcomes the defects in the prior art to some extent at least.

The embodiment of the application provides a method and a device for controlling a display screen of an air conditioner, the air conditioner and a readable storage medium. The air conditioner display screen control device can be integrated in an air conditioner, the air conditioner can adopt a working mode of independent operation or an equipment cluster working mode, and for example, the air conditioner can be a multi-connected air conditioner.

The execution main body of the air conditioner display screen control method in the embodiment of the present application may be the air conditioner display screen control device provided in the embodiment of the present application, and may also be an air conditioner, and hereinafter, the air conditioner is taken as the execution main body for example, and it should be noted that the air conditioner is taken as the execution main body for example only for convenience of understanding, and is not taken as a limitation to the present application.

Referring to fig. 1, fig. 1 is a schematic view of a scene of an air conditioner display screen control system according to an embodiment of the present application. The air conditioner display screen control system may include an air conditioner 100, and an air conditioner display screen control device is integrated in the air conditioner 100.

In addition, as shown in fig. 1, the air conditioner display screen control system may further include a memory 200 for storing data.

It should be noted that the scene schematic diagram of the air conditioner display screen control system shown in fig. 1 is only an example, and the air conditioner display screen control system and the scene described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and it can be known by those skilled in the art that the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems along with the evolution of the air conditioner display screen control system and the occurrence of new service scenes.

Referring to fig. 2, fig. 2 is a schematic flowchart of a method for controlling a display screen of an air conditioner according to an embodiment of the present application. It should be noted that, although a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different than that shown or described herein. The control method of the air conditioner display screen comprises the following steps 201 to 204, wherein:

201. and receiving an LTE signal in the area where the air conditioner is located.

The air conditioner can receive an LTE baseband signal, that is, an LTE signal, sent by a cell base station through a Universal Software Radio Peripheral (USRP) module arranged on an indoor unit, so as to use the LTE baseband signal as a signal basis for controlling a display screen. In addition, the USRP module may be further disposed on other home appliances in the area where the air conditioner is located, and then the air conditioner obtains the LTE baseband signal received by the USRP module through bluetooth connection or network connection.

The area where the air conditioner is located refers to the area where the display screen is located. For example, the area where the air conditioner is located may be a room where an indoor unit having a display screen is installed. For example, when the indoor unit is located in a living room, the living room is an area where the air conditioner is located. At this time, the URSP module can accurately receive the LTE signal in the living room, and if the motion state of the user in the living room changes, the LTE signal received by the URSP module is also changed correspondingly, so that the air conditioner can use the LTE signal in the living room as a signal basis for display screen control.

Since the LTE signal is an original signal without any processing, and the information contained therein is mixed together, the air conditioner cannot directly determine how to control the display screen after receiving the LTE signal, and therefore the LTE signal needs to be processed to a certain extent, and step 202 may be executed at this time.

202. And calculating the channel frequency response of the LTE signal according to the LTE signal.

The air conditioner can directly analyze and calculate the LTE signal in the storage space. However, this method may occupy a large amount of computation and storage space of the air conditioner, and may affect the performance of the air conditioner. Therefore, in order not to affect the normal operation of the air conditioner, the received LTE signal may be sent to the cloud server through the wireless communication module (the WIFI module, the NB-IoT module, etc.), and then the LTE signal is analyzed and calculated in the cloud server.

Further, after the air conditioner sends the LTE signal to the cloud server, the air conditioner can perform phase synchronization correction on the LTE signal to remove phase offset caused by time asynchronization of the signal receiving and sending end.

The channel frequency response refers to information that amplitude and phase change with frequency in the LTE signal. The reason for acquiring the channel frequency response is that in the process of transmitting the LTE signal to the LTE signal and receiving the LTE signal by the URSP module, if the motion state of the user changes, the amplitude and the phase of the LTE signal change correspondingly, so that according to the channel frequency response including the amplitude and phase change information, the air conditioner can obtain the specific motion state condition of the user, thereby determining how to control the display screen.

Specifically, in the cloud server, the air conditioner may perform channel estimation processing on the LTE signal. Illustratively, the air conditioner may perform channel estimation processing on the LTE signal by using a blind estimation method or an estimation method based on a training sequence to obtain a channel frequency response. For convenience of understanding, a specific method for obtaining a channel frequency response according to an LTE signal is given in this embodiment, and step 202 includes:

(1) and extracting the reference information measurement value of the LTE signal.

(2) And determining the channel frequency response according to the ratio of the reference information measurement value to a preset information theoretical value.

The reference information measurement value may refer to a Cell-specific reference signal (CRS reference signal) extracted from an LTE signal, and may be understood as a target CRS reference signal that is finally received after an initial CRS reference signal sent by a base station is disturbed and interfered by a propagation. The preset information theoretical value refers to a CRS reference signal obtained according to a local LTE protocol, and may be understood as the above-mentioned initial CRS reference signal, where the initial CRS reference signal and the target CRS reference signal are signals of subcarriers of the same carrier frequency at the same time. Therefore, according to the reference information measurement value and the preset information theoretical value, the influence of the motion state of the user on the LTE signal in the propagation process, namely the channel frequency response, can be determined.

After obtaining the reference information measured value and the preset information theoretical value, the air conditioner may perform certain calculation processing on the reference information measured value and the preset information theoretical value to obtain the channel frequency response. For example, the ratio between the measured value of the reference information and the theoretical value of the preset information may be used as the channel frequency response, and assuming that there is no noise in the propagation path, since the target signal received by the URSP module is equal to the initial signal at the time of transmission multiplied by the channel matrix, and the channel matrix includes the phase and amplitude attenuation of the signal during propagation, the phase and amplitude attenuation, i.e. the channel frequency response, may be obtained by calculating the ratio between the measured value of the reference information and the theoretical value of the preset information. Assuming that the reference information measurement value is R (f, t), and the predetermined information theoretical value is S (f, t), (f, t) represents that R (f, t) and S (f, t) are signals at time t in a subcarrier with carrier frequency f, the channel frequency response can be calculated according to equation (1):

where h (f) is the channel frequency response in the channel in which the subcarrier of carrier frequency f is located.

Besides, as long as the calculated result can accurately represent the motion state of the user, the result can be used as the channel frequency response. For example, the difference between the reference information measurement value and the preset information theoretical value, or the product between the reference information measurement value and the preset information theoretical value may also be used as the channel frequency response. The embodiment of the present application does not limit this.

203. And processing the channel frequency response to obtain the target action type of the user.

The target action type is one of the preset action types corresponding to the channel frequency response. For example, the preset operation types include a rising operation and a falling-asleep operation, and if the channel frequency response corresponds to the falling-asleep operation, the target operation type is the falling-asleep operation.

The air conditioner processes the channel frequency response in various ways, including:

(1) the air conditioner inquires a preset frequency response-action type mapping relation, acquires an action type corresponding to the channel frequency response in the mapping relation, and takes the action type as a target action type.

For example, the air conditioner may compare the obtained channel frequency response with a plurality of preset frequency responses corresponding to action types, and if the similarity between the obtained channel frequency response and one of the preset frequency responses reaches a preset similarity, such as 90%, the action type corresponding to the preset frequency response may be taken as the target action type.

(2) And the air conditioner inputs the channel frequency response into a pre-trained action recognition model, extracts the characteristic vector of the channel frequency response, and carries out prediction processing according to the characteristic vector to obtain the target action type. For convenience of understanding, a specific method for obtaining the target action type is provided in this embodiment, and may specifically include:

(A) and if the channel frequency response is within a preset fluctuation range, calling a preset filter to correct the channel frequency response to obtain a corrected frequency response.

The air conditioner firstly judges whether the LTE signal is disturbed according to the channel frequency response, specifically, whether the LTE signal is disturbed according to the fact that whether the channel frequency response is in a preset fluctuation range is determined, if the channel frequency response is in the fluctuation range, the LTE signal is judged to be disturbed, and at the moment, in order to improve the precision of subsequent steps, a filter which is constructed in advance by software such as matlab and the like can be called to further correct the phase offset of the channel frequency response, so that the corrected frequency response which can be directly input into the action recognition model is obtained. In addition, in order to increase the operation speed of the subsequent steps, a parameter extraction model constructed in advance by software such as matlab and the like can be called, and the signals obtained after phase offset correction are subjected to preliminary feature extraction to obtain corrected frequency response. Conversely, if the channel frequency response is not within the preset fluctuation range, it indicates that the LTE signal is not disturbed, and the subsequent steps may not be performed at this time, so as to reduce unnecessary operations.

It should be noted that this step can also be applied before other channel frequency response processing methods to obtain a corrected frequency response with a small phase offset and subjected to preliminary feature extraction. For example, this step may be applied before querying the mapping relationship between the frequency response and the action type, which is not described herein in detail.

(B) And calling a preset action recognition model, and predicting the correction frequency response to obtain the target human body action type.

The action recognition model may include a Convolutional Neural Network (CNN), in which various functions such as feature extraction and classification prediction are implemented by a Convolutional layer, a pooling layer, and a full connection layer, for example, performing convolution operation on the corrected frequency response by the Convolutional layer to obtain a feature vector, performing pooling operation on the feature vector by the pooling layer, and calculating the pooled feature vector by the full connection layer to obtain a target action type of the user. In addition, a Support Vector Machine (Support Vector Machine) can be used to replace the fully-connected layer to realize the prediction function.

204. And executing a display screen display strategy corresponding to the target action type.

The display strategy corresponding to different action types is preset in the storage space of the air conditioner or the cloud server, one action type corresponds to one display strategy, and a plurality of action types correspond to one display strategy. After the target action type is obtained, the air conditioner inquires a display screen display strategy corresponding to the target action type in the storage space or the cloud server, and then the display screen display strategy is executed.

The display strategy of the display screen can include the display strategy of the brightness of the display screen, can also include the display strategy of the display content of the display screen, or can include both the display strategies. For example, the air conditioner may adjust the brightness of the display screen to different preset brightness according to different target action types, may display different contents on the display screen according to different target action types, or may include both of them. If the action type includes a daily activity action, when the target action type is the daily activity action, it indicates that the user does not enter a sleep state, and the indoor may be in a light-on state, and in order that the user can still see contents displayed in the display screen under strong light, the air conditioner may increase the brightness of the display screen to a preset maximum brightness. When the user is in the daily activity state, the frequency of changing the set room temperature of the air conditioner by the user is higher than that in other cases, so that the air conditioner can set the display content of the display screen to the set room temperature, and the user can conveniently determine the current set room temperature.

To sum up, the embodiment of the present application receives the LTE signal in the area where the air conditioner is located; calculating the channel frequency response of the LTE signal according to the LTE signal; processing the channel frequency response to obtain a target action type of the user; and executing a display screen display strategy corresponding to the target action type. Therefore, the air conditioner display screen control method in the embodiment of the application can determine the target action type of the user according to the received LTE signal, and then determine the display screen display strategy to be executed according to the target action type, does not need to set special signal sending equipment, and is low in cost.

In addition, the air conditioner can also determine a display strategy of the display screen according to the time when the user action is detected and the target action type, so that the intelligence is further improved. Referring to fig. 3, at this time, executing the display policy of the display screen corresponding to the target action type includes:

301. and if the target action type is a night action, acquiring the current time, wherein the night action comprises at least one of a rising action and a getting-off action.

302. And judging whether the current time is in a preset sleep time range.

303. And if the current time is within the sleep time range, adjusting the brightness of the display screen of the air conditioner to a preset default brightness, and displaying the set room temperature and the current time in the display screen.

When the air conditioner judges that the user performs a rising motion of sitting up or standing up from the bed or a motion of getting on or off the bed from the bed according to the channel frequency response, it judges that the target motion type is a rising motion at night. At this time, the air conditioner can inquire the current network time through the networking module to judge whether the current network time is in the sleep time range in which the air conditioner should go to sleep. For example, the sleep time range may be set to 11: 00 pm-8: 00am, if the current time is at 11: 00 pm-8: 00am, and the target action type is the action of getting up at night, then judge that the user wakes up from the sleep state, at this moment for the convenience of the user to see clearly the content that shows in the display screen, can adjust the display screen luminance to higher default luminance, and for the convenience of the user confirm time and temperature when waking up midway, the air conditioner can be after detecting that the target action type is the action of getting up at night, continuously display current time and set for the room temperature in the display screen, therefore the user does not need to additionally take the action of cell-phone or remote controller, more convenience of customers.

If the target action type is an overnight action, but the current time is not at 11: 00 pm-8: 00am, it indicates that the type of the target action detected by the air conditioner may be wrong, or the user gets into bed in the daytime, and at this time, the display strategy of the display screen does not need to be adjusted, or only the display content of the display screen may be adjusted. For example, it may be that the target action type is an overnight action, but the current time is not at 11: 00 pm-8: 00am, the set room temperature and the current time are simultaneously displayed in the display screen.

On the other hand, by combining the current time and the target action type, the display strategy of the wrong display screen can be prevented from being executed when the judgment of the target action type is wrong, and the accuracy of determining the display strategy of the display screen is improved. For example, when the display screen display strategy is determined only according to the target action type, and a user sits at a bedside in the daytime, the target action type may be detected by the air conditioner as a night action, so that the brightness of the display screen is increased by the air conditioner in the daytime, and energy is wasted.

Besides the current time, the air conditioner can also adopt a mode of simultaneously combining the target action type and the current brightness, or the target action type and the current sound volume, and the like, so that the accuracy of determining the display strategy of the display screen is improved. For example, when the air conditioner judges that the target action type is a night action, the air conditioner can receive audio data through a sound acquisition module arranged on an indoor unit and upload the audio data to a cloud server, then the volume information in the audio data is extracted, if the extracted volume information is larger than or equal to preset volume information, the external environment is noisy, a user does not enter a sleep state, and at the moment, the air conditioner can not adjust a display strategy of a display screen in order to avoid executing a wrong display strategy. On the contrary, if the extracted volume information is smaller than the preset volume information, it indicates that the external environment is quite and the user has entered a sleep state, and at this time, the air conditioner may execute the display strategy of the display screen corresponding to the target action type when the user gets up at night, i.e., in this embodiment, the brightness of the display screen is adjusted to the preset default brightness, and the set room temperature and the current time are displayed in the display screen.

For convenience of understanding, a specific method for determining a display strategy of a display screen by combining a target action type and current brightness is provided in the embodiment:

(1) and if the target action type is a night action, acquiring the current brightness of the area, wherein the night action comprises at least one of a rising action and a getting-off action.

(2) And judging the relation between the current brightness and the preset brightness.

(3) And if the current brightness is smaller than the preset brightness, adjusting the brightness of the display screen of the air conditioner to a preset default brightness, and displaying the set room temperature and the current time in the display screen.

Similar to the way of determining the display strategy of the display screen by combining the target action type and the current volume, when the air conditioner judges that the target action type is the action at night, the current brightness in the room can be detected through a light intensity detection module arranged on the indoor unit, then the current brightness is compared with the preset brightness in a cloud server or a storage space, if the current brightness is smaller than the preset brightness, the user turns off the light to enter a sleep state, and no sunlight enters the room from the outside, and the current environment is at night, so that the air conditioner can execute the display strategy corresponding to the target action type when the user is at night. When the current brightness is greater than or equal to the preset brightness, it indicates that the current environment is in the daytime or the user does not turn off the light and enters a sleep state, so that the air conditioner does not need to adjust the display strategy of the display screen or only can adjust the display content of the display screen in order to avoid executing the wrong display strategy of the display screen.

Further, the air conditioner may simultaneously combine multiple determination factors such as the target action type, the current brightness, the current time, and the current volume to improve the accuracy of determining the display strategy of the display screen, which is not described herein in detail.

When the target action type is the night action, the air conditioner can adopt a fixed display screen display strategy, and the air conditioner can also adjust the display screen display strategy in real time according to the historical action of the user so as to improve the intelligence. Referring to fig. 4, the displaying the set room temperature and the current time in the display screen at this time includes:

401. and inquiring the storage space of the air conditioner to obtain the historical night-rising times and the historical temperature-adjusting times of the user.

The historical number of times of getting up at night is the number of times that the air conditioner detects that the target action type is the action of getting up at night in the past. For example, the air conditioner may take the number of times that the target action type is detected as the overnight action in the past period as the historical number of times of the night. For example, the air conditioner may query the storage space, and then obtain the number of records in which the target action type is detected as the overnight action in the past month, and use the number of records as the historical number of times of the night.

The historical temperature adjustment times are the times that the air conditioner continuously detects that the set room temperature is changed after detecting the night action. For example, the air conditioner may determine each of the historical night-times as follows: whether a record that the set room temperature is changed after a preset time interval of the overnight action is detected can be inquired, if the record that the set room temperature is changed exists, the record is counted once, and the total number of the counted number can be used as the historical temperature adjusting times. For example, the historical number of times of the night is 3, which are 1 month, 1 day, 1:00,1 month, 2 days, 1:00, and 1 month, 3 days, 1:00, respectively, and the air conditioner may determine whether the set room temperature is changed within 1 minute after the three time points, respectively, and if the set room temperature is changed within 1 month, 1 day, 1:00-1 month, 1 day, 1:01, and the set room temperature is not changed within 1 minute after the other time points, the historical number of times of the night is 1. It should be noted that if a plurality of records in which the set room temperature is changed can be inquired after detecting the preset time interval of the overnight action, the records are still counted once.

402A, if the ratio of the historical temperature adjustment times to the historical night times is smaller than a preset threshold value, and the historical night times is larger than or equal to the preset times, displaying the set room temperature and the current time in the display screen according to a preset first content display strategy.

The first content display strategy is a display strategy related to display content in a display screen, and in the embodiment of the application, the first content display strategy is a display strategy related to set room temperature and current time. Illustratively, the first content display policy may be related to a display order in which the room temperature and the current time are set. For example, the first content display policy may include: the set room temperature is displayed first, and the current time is continuously displayed after 1 minute.

If the ratio of the historical temperature adjusting times and the historical night-rising times calculated by the air conditioner is smaller than the preset threshold value, the fact that the user gets up habitually is proved, the probability of changing the set room temperature after getting up is low, the set room temperature set by the user before sleeping in habit can be judged, or the set room temperature set by the air conditioner automatically belongs to comfortable temperature, and the reason of the night-rising behavior is irrelevant to the set temperature of the air conditioner. Because the user does not need to change the set room temperature after getting up, the requirement for obtaining the set room temperature is low, and the current time is preferentially displayed at the moment, so that the user can judge whether to need to carry out work preparation or not, or whether to go to sleep continuously or not, and the current requirement of the user is better met, and therefore the air conditioner can execute the following first display strategy: the current time is displayed first, and then the set room temperature and the current time are alternately displayed. Further, the air conditioner may also adjust the current time and the display time of the set room temperature to match the current needs of the user. For example, the air conditioner may set the display time of the current time to be 5 seconds, which is long, and the display time of the set room temperature to be 3 seconds, which is short.

In addition, the air conditioner may also employ a first display strategy different from that described above. For example, the first display policy may include: and simultaneously displaying the current time and the set room temperature on a display screen, wherein the display font of the current time is larger than that of the set room temperature. Alternatively, the first display policy may further include: and simultaneously displaying the current time and the set room temperature on the display screen, wherein the display font color of the current time is red or blue with bright hue, and the like, and the display font color of the set room temperature is gray with dark hue, and the like.

The reason for judging the relation between the historical night-out times and the preset times is to ensure that the historical night-out times are large enough so as to avoid the judgment error of the user night-out reasons when the historical night-out times are too small and further execute an error display screen display strategy.

402B, if the ratio of the historical temperature adjustment times to the historical night times is larger than or equal to a preset threshold value, and the historical night times is larger than or equal to the preset times, displaying the set room temperature and the current time in the display screen according to a preset second content display strategy.

The meaning of the second content display policy may refer to the meaning of the first content display policy, and is not described herein again. However, it should be noted that the second display policy is a display policy different from the first display policy because the user has different requirements for acquiring the current time and the set room temperature under different conditions.

If the ratio of the historical temperature adjustment times to the historical night-rising times calculated by the air conditioner is larger than or equal to the preset threshold value, the fact that the user is used to set the set room temperature before sleeping is indicated, or the set room temperature automatically set by the air conditioner is easy to enable the user to have night-rising behaviors, the user needs to change the set room temperature after getting up, therefore, the user has a high requirement for obtaining the set room temperature, the set room temperature is preferentially displayed at the moment, the user can adjust the set room temperature, and the current requirement of the user is better met. The air conditioner may thus perform the following second display strategy: the set room temperature is displayed first, and then the current time and the set room temperature are alternately displayed. Likewise, the air conditioner may adjust the display time of the current time and the set room temperature, for example, the air conditioner may set the display time of the set room temperature to 5 seconds, which is longer, and the display time of the current time to 3 seconds, which is shorter.

Similarly, the air conditioner may further adopt a second display policy different from the above, which may specifically refer to the description of the first display policy above, and will not be described herein again.

Therefore, through the steps 401 to 402A or the steps 401 to 402B, the air conditioner can judge the current requirement of the user according to the historical actions of the user so as to adjust the display strategy of the display screen in real time.

If the air conditioner judges that the user starts to sleep and does not detect that the user is getting up at night, the display screen can be correspondingly adjusted to avoid influencing the sleep of the user. Referring to fig. 5, at this time, executing the display policy of the display screen corresponding to the target action type includes:

501. and if the target action type is the action of falling asleep, continuously detecting the detection action type of the user within preset detection time.

The action of falling asleep may include actions of getting up to bed, lying down, etc. which represent that the user starts to sleep. If the air conditioner detects the action, the action type made by the user is continuously detected within a preset detection time, such as 10 minutes, namely the detection action type. The purpose of the air conditioner acquiring the detection action type is to determine whether the user performs the action of falling asleep for sleeping, for example, the user may go to bed or lie down for more comfortable use of the mobile phone or reading, and at this time, if the display strategy of the display screen is directly adjusted, the experience of the user may be affected.

502. And if the detection action type does not contain a night action, turning off a display screen of the air conditioner, wherein the night action comprises one of a rising action and a getting-off action.

If the detected action type does not contain the action of getting up at night, the fact that the user performs the action of falling asleep is to sleep, and at the moment, the air conditioner can turn off the display screen in order to avoid the influence of the brightness of the display screen of the air conditioner on the sleep of the user. Or the air conditioner can adjust the brightness of the display screen to a lower preset brightness, so that the display screen is prevented from being frequently turned on and off when the user switches between the waking state and the sleeping state for many times, the user can see the content displayed in the display screen while waking up, and convenience is brought to the user.

If the detection action type includes the night action, the air conditioner performs the step 301 to the step 303, the step 401 to the step 402A, or the step 401 to the step 402B.

In order to further accurately judge whether the user is asleep, the air conditioner can further judge the sleep stage of the user according to the detected action type so as to determine the display strategy of the display screen. Referring to fig. 6, at this time, if the detection action type does not include the night action, turning off the display screen of the air conditioner includes:

601. and if the detection action type does not contain the night action, acquiring the turn-over times of the turn-over action in the detection action type.

602. And if the turning-over times are less than the preset turning-over times, turning off the display screen of the air conditioner.

The purpose of the air conditioner for detecting the turnover frequency is to judge the sleep stage of the user. When the turning-over times are more, the user is not asleep, the brightness of the display screen of the air conditioner does not cause the user to wake up from the sleep, and the appropriate indoor illumination is more beneficial to the user to sleep. Therefore, if the turning times is more than or equal to the preset turning times, the display screen of the air conditioner is not extinguished.

Conversely, if the number of turns is small, it indicates that the user has entered a deep sleep state, and if the light of the display screen is shone on the face of the user, the user may be awakened, which may affect the sleep quality of the user. Therefore, if the turning-over times are less than the preset turning-over times, the display screen of the air conditioner is extinguished.

In addition, the air conditioner can also judge the sleep stage of the user in other modes. For example, the air conditioner can obtain audio data in a room through a sound acquisition module arranged on the indoor unit, and then judge whether the user snores according to the audio data, if the user snores, the user enters a deep sleep state, and at the moment, the display screen of the air conditioner needs to be turned off. Specifically, the air conditioner may call a preset sound recognition model, perform feature extraction on the audio data to obtain an audio feature vector, perform prediction processing according to the audio feature vector to obtain a sound category of the audio data, and if snore occurs in the sound category, may determine that the user snores.
