As an implementable solution, a plurality of operation states may be prestored in the air conditioner. And judging the type of the environmental sound according to the environmental sound information, wherein each type corresponds to an operation state. And when the type of the environmental sound is judged according to the sound information, controlling the air conditioner to operate in an operation state corresponding to the type of the environmental sound.
Further, the operation state of the air conditioner includes an outlet air temperature and/or an air speed of the air conditioner. The air outlet temperature and the air speed are easy to perceive and change the feeling of the user, so that the requirements of the user can be met by adjusting the air outlet temperature and the air speed.
In an embodiment of the present invention, the air conditioner further includes an augmented reality terminal, and the step of controlling the operation state of the air conditioner according to the environmental sound information of the target area further includes:
and controlling the augmented reality terminal to render the augmented reality scene in the target area according to the type of the environmental sound.
According to the type of the environmental sound, the environment atmosphere can be presumed to a certain extent, and the augmented reality scene rendering of the augmented reality terminal to the target area is automatically adjusted according to the environment atmosphere. For example, when the frequency fluctuation of the ambient sound is large and the volume is large, it is presumed that the atmosphere of the target area may be hot, and for example, the target area may be a peak time in a singing hall or a dance hall. Therefore, the augmented reality terminal can render a more enthusiasm style, such as increasing the light flicker frequency and the like.
In an embodiment of the present invention, the air conditioner has an environmental mode, and the step of acquiring environmental sound information of the target area specifically includes:
acquiring environmental sound information for multiple times at intervals within a first preset time after entering an environmental mode;
the step of judging the type of the environmental sound according to the environmental sound information specifically comprises the following steps:
and judging the type of the environmental sound according to the environmental sound information acquired for multiple times within the first preset time after entering the environmental mode.
In the scheme, the type of the environmental sound can be judged comprehensively through the environmental sound information collected for multiple times within the first preset time, so that the judgment accuracy is improved.
In an embodiment of the present invention, the step of obtaining the environmental sound information of the target area further includes:
after entering an environment mode and passing a first preset time, acquiring environment sound information once every a second preset time;
the step of judging the type of the environmental sound according to the environmental sound information further comprises:
and respectively judging the type of the environmental sound again according to the environmental sound information acquired every time after the environmental sound enters the environmental mode and the first preset time passes.
In the scheme, further, after the environmental mode is entered and the first preset time passes, the type of the environmental sound is already determined, the environmental sound information is acquired every second preset time subsequently to confirm whether the type determined last time is correct, and if the type is changed, the type of the environmental sound is determined again and the running state of the air conditioner is adjusted in real time.
In an embodiment of the present invention, the air conditioner has an environmental mode, and before obtaining the environmental sound information of the target area, the method for controlling the air conditioner further includes receiving an instruction to enter the environmental mode, the environmental sound information further includes a volume of the environmental sound, and the step of controlling the operating state of the air conditioner according to the environmental sound information of the target area specifically includes:
when the volume of the environmental sound is smaller than a preset value, controlling the air conditioner to operate in an initial mode, wherein the initial mode is a mode preset by a user or a mode before the air conditioner enters the environmental mode;
when the volume of the environmental sound is not less than the preset value, the air outlet temperature is reduced on the basis of the initial mode according to the volume and the frequency of the environmental sound.
In the scheme, a preset value related to the volume is set to be used as a basis for judging whether the running state of the air conditioner needs to be adjusted. When the volume of the environmental sound is small (smaller than the preset value), the influence of the sound on the user can be presumed to be small, so that the operation can be continued in the initial mode without adjusting the operation state. The initial mode may be a mode before the air conditioner enters the ambient mode. If the air conditioner is directly in the ambient mode when it is turned on, the initial mode may be a mode preset by the user. When the volume of the environmental sound is larger than the preset value, the influence of the environmental sound on the user can be presumed, and therefore the air outlet temperature is reduced on the basis of the initial mode according to the volume and the frequency of the environmental sound. Because the environmental sound is great, can lead to the human heat production more (the mood causes such as excited, dysphoria), consequently reduce the air-out temperature and can satisfy user's demand better. The degree of the reduction can be determined according to the volume and the frequency of the environmental sound.
In an embodiment of the present invention, when the volume of the environmental sound is not less than the preset value, the step of reducing the outlet air temperature based on the initial mode according to the volume and the frequency of the environmental sound specifically includes:
when the frequency of the environmental sound is in a first preset frequency interval, controlling the air outlet temperature of the air conditioner to be adjusted at a first change rate along with the volume of the environmental sound;
when the frequency of the environmental sound is in a second preset frequency interval, controlling the air outlet temperature of the air conditioner to be adjusted at a second change rate along with the volume of the environmental sound;
any frequency value in the first preset frequency interval is smaller than any frequency value in the second preset frequency interval, and the absolute value of the first change rate is smaller than the absolute value of the second change rate.
In the scheme, if the environmental sound is at a low frequency, the influence of the environmental sound on the heat production of the human body can be presumed to be small, and on the contrary, the influence on the heat production of the human body is large. Therefore, when the ambient sound is in a first lower preset frequency interval, the outlet air temperature is reduced less when the unit volume is increased; when the ambient sound is in a second higher preset frequency interval, the outlet air temperature is reduced more when the unit volume is increased.
Further, the preset value is 35-45 db, the first preset frequency interval is 0-2KHz, and the second preset frequency interval is more than 2 KHz. Through setting up reasonable parameter, can satisfy user's user demand better, improve user's experience.
In one embodiment of the present invention, the step of controlling the operation state of the air conditioner according to the ambient sound information of the target area further includes:
under the condition of refrigeration, when the volume of the environmental sound is not less than a preset value, the wind speed is increased on the basis of an initial mode according to the volume of the environmental sound;
under the heating condition, when the volume of the environment sound is not smaller than a preset value, the wind speed is reduced on the basis of the initial mode according to the volume of the environment sound.
In this scheme, except adjusting the air-out temperature, can also adjust the wind speed. In the case of cooling, when the user in the target area increases the human body's heat production because of the atmosphere in which it is located, the wind speed is increased to enhance cooling. Under the condition of heating, because the heat production of the user is increased due to the environmental sound, the wind speed can be reduced, the heating is reduced, the over-dry heat of the user is avoided, and the energy consumption is reduced.
In a second aspect, an embodiment of the present invention provides a control device for an air conditioner, including:
the sound acquisition module is used for acquiring environmental sound information of the target area;
and the adjusting module is used for controlling the running state of the air conditioner according to the environmental sound information of the target area, wherein the environmental sound information comprises the frequency of the environmental sound.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
In the prior art, in the process of cooling or heating a target area by an air conditioner, if the environmental atmosphere of the target area changes, which causes a change in the operation requirement of a user on the air conditioner, the operation state of the air conditioner needs to be manually adjusted. In some occasions, the environmental atmosphere changes frequently, or the environmental atmosphere changes along with the activity state of people in the target area, and the running state of the air conditioner cannot be adjusted in time because an individual can stay in the target area for a short time and cannot perceive the environmental changes in time. For example, in a subway station, the passenger demands are different because the passenger flow rate is different between the peak time and the non-peak time and the environmental atmosphere is different. During peak periods, the flux of people is high and lower temperatures are required than during non-peak periods. There are also multi-functional halls that are suitable for many occasions, such as meetings, musical performances, etc., and the required temperature, wind speed may all be different for different suitable occasions. Therefore, the users in the target area need to adjust the operation state of the air conditioner according to their own needs. And frequent adjustments can be cumbersome and may result in untimely.
In order to solve the above problems, embodiments of the present invention provide a control method and a control device for an air conditioner, and a storage device. The following describes the air conditioner 1. Fig. 1 is a block diagram showing the components of an air conditioner 1 according to an embodiment of the present invention. Referring to fig. 1, an air conditioner 1 according to an embodiment of the present invention includes a sound collection device 3, a heat exchange assembly 5, an air outlet assembly 4, an augmented reality terminal 6, and a controller 2. The sound collection device 3, the heat exchange assembly 5, the air outlet assembly 4 and the augmented reality terminal 6 are electrically connected with the controller 2 respectively.
In the present embodiment, the sound collection device 3 is used to collect the environmental sound information of the target area and send the information to the controller 2, and in the present embodiment, the sound collection device 3 may be a microphone.
The air outlet assembly 4 can be controlled by the controller 2 to adjust the air outlet speed, the air direction and the like, and the air outlet assembly 4 comprises at least one fan, such as a cross-flow fan or an axial flow fan. The heat exchange assembly 5 can be controlled by the controller 2 to adjust the temperature of the coil pipe and combine the air outlet assembly 4 to adjust the temperature of the air outlet together. In this embodiment, the air conditioner in the prior art can be referred to in the setting mode of the heat exchange assembly 5 and the air outlet assembly 4, and details are not repeated here.
In this embodiment, the augmented reality terminal 6 includes a light emitting component, which can be controlled by the controller 2 to project a pattern in the target area or to flash or to perform a color gradient according to a certain rule. The augmented reality terminal 6 is used for rendering the environment atmosphere and giving better experience to the user. Of course, the augmented reality terminal 6 may further include other devices such as a speaker to implement more real scene rendering functions.
The controller 2 of the embodiment of the present invention is configured to: acquiring environmental sound information of a target area; the operation state of the air conditioner 1 is controlled according to the ambient sound information of the target area, wherein the ambient sound information includes the frequency of the ambient sound. By acquiring the environmental sound information including the frequency, the scene of the target area can be estimated, so that the requirements of users in the target area can be judged, and the running state of the air conditioner can be further adjusted. The scheme controls the running state of the air conditioner 1 according to the environmental sound information, and improves the inconvenience brought by manual adjustment of users according to the requirements of the users. Because the melody, tone and the like of the sound can cause the change of the blood pressure, breath and the like of the human body, the high and low of the sound and the volume can cause the change of the heat production capacity of the human body. For example, the sound frequency is high, the volume is high, the human body is excited, and the heat generation is high, so that the operation state of the air conditioner may need to be adjusted to meet the needs of the human body at the moment.
Fig. 2 is a flowchart of a control method of the air conditioner 1 according to the embodiment of the present invention. As shown in fig. 2, the control method of the air conditioner 1 includes:
step S200, obtaining the environmental sound information of the target area.
Taking the air conditioner 1 provided by the embodiment of the present invention as an example, the controller 2 may obtain the environmental sound information of the target area through the sound collection device 3. The target area is an area to which the air conditioner 1 performs heating and cooling operations. The mode of acquiring the environmental sound information by the sound acquisition device 3 may be to acquire one or more audio frequencies and upload the audio frequencies to the controller 2 for further judgment. Further, the starting condition of step S200 may be that the air conditioner 1 enters the ambient mode, and thus the control method may further include receiving an instruction to enter the ambient mode input by the user before step S200. After receiving the instruction to enter the ambient mode, the controller 2 controls the air conditioner 1 to enter the ambient mode, and thereby performs step S200 and subsequent steps.
Step S400, controlling the running state of the air conditioner according to the environment sound information of the target area, wherein the environment sound information comprises the frequency of the environment sound.
Taking the air conditioner 1 provided by the embodiment of the invention as an example, the controller 2 can preliminarily judge the requirements of users in the target area according to the environmental sound information, so as to adjust the running state of the air conditioner. For example, the ambient sound is loud, the frequency is high, it can be determined that the user is easily in a excited state due to the ambient sound, and the heat generated by the user is high, so that the sensible temperature needs to be reduced. The running state of the air conditioner 1 comprises the air outlet temperature and the air speed, so that the air conditioner 1 can be adjusted by the air outlet assembly 4 and the heat exchange assembly 5 when the user sensible temperature needs to be reduced.
Fig. 3 is a flowchart illustrating an operation state of the air conditioner 1 according to the ambient sound information of the target area according to an embodiment of the present invention. As shown in fig. 3, on the basis of the embodiment of fig. 2, step S400 may further include:
step S401, judging the type of the environmental sound according to the environmental sound information.
Taking the air conditioner 1 provided by the embodiment of the present invention as an example, the air conditioner 1 is pre-stored with a plurality of sound types, each sound type corresponds to an operation state of the air conditioner 1, and each operation state is stored in the memory in the form of an operation parameter. After the ambient sound is collected, the controller 2 analyzes the ambient sound information, and classifies the ambient sound by its volume, frequency, rhythm, and the like to determine the type to which the ambient sound belongs. For example, the ambient sound is determined to be of a type such as "mild", "exciting", "cheerful", "noisy" or the like according to the frequency and fluctuation of the ambient sound. Or the application places are classified into types such as supermarket, bar, dance hall, station, conference, music hall and the like, and each type corresponds to a corresponding running state. It should be understood that the operating state parameters for each sound type may also be adjusted by the user to meet personalized needs.
And step S402, controlling the air conditioner to operate in an operating state corresponding to the type of the environmental sound.
When the type of the environmental sound is determined based on the sound information, the controller 2 controls the air conditioner 1 to operate in an operation state corresponding to the type of the environmental sound. For example, in a noisy environment with a high sound frequency, the outlet air temperature of the air conditioner 1 may be controlled to decrease. Further, if the air conditioner is in a refrigeration state, the air speed is increased, and refrigeration is enhanced; if the air is in a heating state, the air speed is reduced, and heating is reduced. Taking the refrigeration of a subway station as an example, the refrigeration is noisy in the peak period, the people flow is large, the required temperature is low compared with the off-peak period, the temperature is controlled to be reduced at the moment, and the wind speed is correspondingly increased.
In the embodiment of fig. 3, the step of acquiring the ambient sound information of the target area before determining the type of the ambient sound may include: and acquiring the environmental sound information for multiple times at intervals within a first preset time after entering the environmental mode. The step of determining the type of the environmental sound according to the environmental sound information may include: and judging the type of the environmental sound according to the environmental sound information acquired for multiple times within the first preset time after entering the environmental mode.
For example, within one minute after entering the ambient mode, the ambient sound information is acquired 3 times, and the type of the ambient sound is determined by the ambient sound information acquired three times. For example, the average value, median, etc. of the frequency and the volume in the sound clip obtained three times are taken as the basis for judgment, or the difference between the highest frequency and the lowest frequency, and the highest volume and the lowest volume is taken as the basis for judging the type of the environmental sound. In the scheme, the type of the environmental sound can be judged comprehensively through the environmental sound information collected for multiple times within the first preset time, so that the judgment accuracy is improved.
Further, in order to make the air conditioner 1 adjust in real time when the subsequent ambient sound changes state, the step of acquiring the ambient sound information of the target area may further include: after entering the ambient mode and the first preset time, ambient sound information is acquired every second preset time. Further, the step of determining the type of the environmental sound may further include: and respectively judging the type of the environmental sound again according to the environmental sound information acquired every time after the environmental sound enters the environmental mode and the first preset time passes. After entering the ambient mode and the first preset time has elapsed, the type of the ambient sound is determined, and then the ambient sound information is acquired again every second preset time to confirm whether the type determined last time is correct, and if the type has changed, the type of the ambient sound is re-determined and the operation state of the air conditioner 1 is adjusted in real time. For example, within one minute after entering the ambient mode, the ambient sound information is acquired 3 times to preliminarily determine the type of the ambient sound and determine the operating state of the air conditioner 1; then, the type of the environmental sound is acquired every one minute, and the operation state of the air conditioner 1 is adjusted in real time.
In an alternative embodiment of the present invention, the step of controlling the operation state of the air conditioner 1 may further include: and controlling the augmented reality terminal 6 to perform augmented reality scene rendering on the target area according to the type of the environmental sound.
According to the type of the environmental sound, the environment atmosphere can be presumed to a certain extent, and the augmented reality terminal 6 is automatically adjusted to render the augmented reality scene in the target area according to the environment atmosphere. For example, when the frequency fluctuation of the ambient sound is large and the volume is large, it is presumed that the atmosphere of the target area may be hot, and for example, the target area may be a peak time in a singing hall or a dance hall. Therefore, the augmented reality terminal 6 can render a more enthusiasm style, such as increasing the light flashing frequency. When the sound fluctuation is small and the volume is stable, the background noise can be presumed, the user activity is mild, and only stable light emission is needed. In addition, the augmented reality terminal 6 can also project corresponding theme pictures according to needs, for example, in a children room, there is children's voice, but other types of noises are less, and under such an environment, the augmented reality terminal 6 can project cartoon patterns and the like, or play children's songs and stories, so as to create an environment suitable for children. When the environmental sound is very small and the frequency is low, for example, a starry sky picture can be projected to create silent and romantic atmosphere. It should be understood that in other embodiments, the augmented reality terminal 6 may also selectively project a theme pattern of a new house with a sweet style or a related theme pattern with a retro style, a mediterranean style, a southeast asian style, and the like according to an instruction of the user or based on a judgment of the environment. Therefore, the room style can be easily converted, the life interest is increased, the whole house decoration cost is saved, and the space occupied by equipment installation is reduced.
Fig. 4 is a flowchart for controlling the operation state of the air conditioner 1 according to the ambient sound information of the target area in another embodiment of the present invention. The air conditioner 1 has an ambient mode, and before acquiring the ambient sound information of the target area, the control method of the air conditioner 1 further includes receiving an instruction input by a user to enter the ambient mode, and the ambient sound information further includes a volume of the ambient sound. As shown in fig. 4, on the basis of the embodiment of fig. 2, step S400 may further include:
in step S411, it is determined whether the volume of the environmental sound is less than a preset value.
When the volume of the environmental sound is smaller than the preset value, step S412 is executed: and controlling the air conditioner to operate in an initial mode, wherein the initial mode is a mode preset by a user or a mode before the air conditioner enters an environment mode.
When the volume of the environmental sound is not less than the preset value, step S413 is performed: according to the volume and the frequency of the environmental sound, the air outlet temperature is reduced on the basis of the initial mode.
Taking the air conditioner 1 provided by the embodiment of the present invention as an example, the sound collection device 3 may be used to collect the environmental sound segments for multiple times, and then the average value is taken as the representation value of the volume of the environmental sound. When the volume of the ambient sound is less than the preset value, the air conditioner 1 is controlled to operate in the initial mode. The initial mode may be a mode before the air conditioner 1 enters the ambient mode. If the air conditioner 1 directly enters the ambient mode at the time of power-on, the initial mode here may be a mode preset by the user. In the present embodiment, a preset value related to the volume is set as a basis for determining whether the operation state of the air conditioner 1 needs to be adjusted. When the volume of the environmental sound is small (smaller than the preset value), the influence of the sound on the user can be presumed to be small, so that the operation can be continued in the initial mode without adjusting the operation state. When the volume of the environmental sound is larger than the preset value, the influence of the environmental sound on the user can be presumed, and therefore the air outlet temperature is reduced on the basis of the initial mode according to the volume and the frequency of the environmental sound. Because the environmental sound is great, can lead to the human heat production more (probably because of the mood arouses such as excited, dysphoria), consequently reduce the air-out temperature and can satisfy user's demand better. The degree of the reduction can be determined according to the volume and the frequency of the environmental sound. Further, the preset value is 35-45 db, such as 40 db.
In an embodiment of the present invention, step S413 may specifically include: when the frequency of the environmental sound is in a first preset frequency interval, controlling the air outlet temperature of the air conditioner 1 to be adjusted at a first change rate along with the volume of the environmental sound; when the frequency of the environmental sound is in a second preset frequency interval, controlling the air outlet temperature of the air conditioner 1 to be adjusted at a second change rate along with the volume of the environmental sound; any frequency value in the first preset frequency interval is smaller than any frequency value in the second preset frequency interval, and the absolute value of the first change rate is smaller than the absolute value of the second change rate.
In an alternative embodiment, the first predetermined frequency interval may be set to 0-2KHz, and the second predetermined frequency interval may be set to 2KHz or more. Taking refrigeration as an example, when the volume of the environmental sound is above 40 db and the frequency is in the interval of 0-2KHz, the outlet air temperature is reduced by 1 degree centigrade every time the volume is increased by 10 db. When the volume of the environmental sound is above 40 decibels and the frequency is above 2KHz, the air outlet temperature is reduced by 1 ℃ when the volume is increased by 5 decibels.
Further, in the cooling mode, when the volume of the environmental sound is not less than a preset value, the wind speed can be increased on the basis of the initial mode according to the volume of the environmental sound. The wind speed increase amount can be determined according to the amount of the environmental sound exceeding the preset value on the basis that the environmental sound is larger than the preset value. In a specific embodiment, when the sound frequency is 0-2KHz, the wind speed is increased by one gear every 10 decibels of increase of the volume on the basis of a preset value; when the sound frequency is in the interval above 2KHz, the wind speed is also increased by one gear every time the volume is increased by 5 decibels.
Similarly, in the case of heating, the control mode of the outlet air temperature may be the same as that of cooling, except that in the case of heating, when the volume of the environmental sound is not less than the preset value, the wind speed is reduced on the basis of the initial mode according to the volume of the environmental sound. Since hot air is discharged in the heating mode, the air volume should be reduced in order to avoid an excessively high temperature sensed by the user. Further, the wind speed reduction amount can be determined according to the amount of the environmental sound exceeding the preset value on the basis that the environmental sound is larger than the preset value. In a specific embodiment, when the sound frequency is 0-2KHz, the wind speed is reduced by one gear every time the volume is increased by 10 decibels on the basis of a preset value; when the sound frequency is in the interval above 2KHz, the wind speed is reduced by one gear when the volume is increased by 5 decibels. It should be understood that the first gear is taken as the minimum unit of wind speed adjustment in the present embodiment, and therefore, the wind speed difference between the gears can be set as required. In alternative embodiments, the wind speed may also be adjusted steplessly.
In the scheme, if the environmental sound is at a low frequency, the influence of the environmental sound on the heat production of the human body can be presumed to be small, and on the contrary, the influence on the heat production of the human body is large. Therefore, when the ambient sound is in a first lower preset frequency interval, the outlet air temperature is reduced less when the unit volume is increased; when the ambient sound is in a second higher preset frequency interval, the outlet air temperature is reduced more when the unit volume is increased. Except that adjustment air-out temperature, this scheme still further adjusts the wind speed. In the case of cooling, when the user in the target area increases the human body's heat production because of the atmosphere in which it is located, the wind speed is increased to enhance cooling. Under the condition of heating, because the heat production of the user is increased due to the environmental sound, the wind speed can be reduced, the heating is reduced, the over-dry heat of the user is avoided, and the energy consumption is reduced.
Furthermore, on the basis of the setting mode, a threshold value for adjusting the air outlet temperature and the air speed can be set. For example, in the case of refrigeration, the outlet air temperature is not lower than a threshold (for example, 16 ℃), and the air speed does not exceed the maximum air speed set by the air conditioner; in the heating condition, the outlet air temperature is not lower than another threshold (for example, 15 ℃), and the air speed is not lower than the minimum air speed set by the air conditioner.
