Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, 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 invention.
In this application, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
As known from the background art, when a user feels dry in the process of using the air conditioner, the user needs to control the operation of an air conditioner internal unit through an air conditioner remote controller, so that the purpose of adjusting indoor humidity is achieved. However, the aforementioned method for adjusting indoor humidity requires a user to know how to control the air conditioner internal unit to adjust indoor humidity, and the user needs to manually operate the air conditioner remote controller to control the air conditioner, which wastes user time and affects user experience.
Therefore, the embodiment of the invention provides an air conditioner control method and system, wherein a first image of a part appointed by a user is acquired when an air conditioner indoor unit is started, and a second image of the appointed part is acquired every other preset time in the operation process of the air conditioner indoor unit. Whether the body of the user becomes dry or not is determined by comparing the first image with the second image, and if the body becomes dry, the operation of the air conditioner indoor unit is controlled according to the current indoor temperature and the current operation parameters of the air conditioner indoor unit, so that the indoor humidity is adjusted, the time of the user is saved, and the use experience of the user is improved.
Referring to fig. 1, a flowchart of an air conditioner control method according to an embodiment of the present invention is shown, where the air conditioner control method includes:
step S101: when the air conditioner indoor unit is started, a first image of a designated part of a user is acquired.
In the process of implementing step S101 specifically, when the air conditioner internal unit is powered on to operate, an image capture device (such as a camera) disposed on the air conditioner internal unit is used to capture a first image of a designated portion of a user. When the first image is obtained, the first image may be directly obtained from the image collecting device, or the image collecting device may first send the first image to a designated APP, and then obtain the first image from the designated APP, where the manner of obtaining the first image is not particularly limited.
The designated region is a lip or a designated facial region, that is, a region that can reflect a dry body state of the user, and the designated region is not particularly limited herein.
Step S102: and after the air conditioner indoor unit operates for a preset time each time, acquiring a second image of the designated part.
In the process of implementing step S102 specifically, a preset time is preset, and after the air conditioner internal unit is started to operate (the first image is acquired), the image acquisition device is used to acquire the second image of the designated portion of the user every preset time in the operation process, so as to acquire the second image.
It can be understood that specific contents of the second image are obtained, which are referred to in the above step S101 and are not described herein again.
Step S103: and comparing the first image with the second image, and determining body dryness change information of the user according to the comparison result.
It can be understood from the foregoing that the designated portion is a portion that can reflect the body dryness status of the user, and therefore the body dryness change information of the user can be determined from the image of the designated portion.
In the process of implementing step S103 specifically, the first image is an image of a specified part of the user acquired when the air conditioner internal unit is started, and the second image is an image of the specified part of the user acquired in the operation process of the air conditioner internal unit.
And obtaining body drying change information for determining whether the body of the user is dry or not by comparing the first image with the second image, and controlling the operation of an air conditioner internal unit according to the body drying change information so as to adjust the indoor humidity.
Step S104: and if the body drying change information indicates that the body of the user becomes dry, controlling the air conditioner internal unit to operate according to the current indoor temperature and the current operation parameters of the air conditioner internal unit.
It should be noted that the current operation parameters include an operation mode and a set temperature, and the operation mode is a cooling mode, a dehumidification mode or a heating mode.
It can be understood that, when the operation mode of the air conditioner indoor unit is the cooling mode or the dehumidification mode, the indoor humidity is too low (for example, the humidity is lower than 40%) in the cooling process, or the indoor humidity is too low due to excessive dehumidification in the dehumidification process, the body of the user is dried, and at the moment, the operation of the air conditioner indoor unit needs to be controlled, so that the indoor humidity is adjusted.
When the operation mode of the air conditioner indoor unit is the heating mode, the indoor temperature rises and simultaneously the indoor humidity is reduced, the body of a user becomes dry, and the operation of the air conditioner indoor unit needs to be controlled at the moment, so that the indoor humidity is adjusted.
Therefore, in the process of implementing step S103 specifically, when the body dryness change information indicates that the body of the user becomes dry, the operation state of the air conditioner internal unit is controlled by using the acquired current indoor temperature and the current operation parameter of the air conditioner internal unit, thereby achieving the effect of adjusting the indoor humidity.
It should be noted that, when the indoor humidity is adjusted by controlling the operation state of the air conditioner internal unit, the manner of controlling the air conditioner internal unit is different according to the different operation modes of the air conditioner internal unit, and the details of how to control the operation state of the air conditioner internal unit are described in the following.
When the operation mode of the air conditioner indoor unit is a refrigeration mode or a dehumidification mode, the mode of controlling the air conditioner indoor unit is as follows:
the inventor finds that when the air conditioner indoor unit is used for refrigerating, the dehumidification capacity of the air conditioner indoor unit can be reduced by reducing the air supply speed of the air conditioner indoor unit, and therefore indoor humidity is improved.
If the current indoor temperature is less than or equal to the set temperature of the air conditioner indoor unit (namely the air conditioner indoor unit achieves the refrigeration effect preset by a user), and the operation mode is the refrigeration mode, the air supply gear of the air conditioner indoor unit is reduced to the lowest gear.
If the current indoor temperature is less than or equal to the set temperature of the air conditioner indoor unit, and the operation mode is the dehumidification mode, the air supply gear of the air conditioner indoor unit is reduced (namely, the dehumidification wind gear of the air conditioner indoor unit is reduced), for example, the air supply gear of the air conditioner indoor unit is reduced by one gear (several gears are reduced according to actual conditions), it can be understood that before the air supply gear is reduced, if the air supply gear is the lowest gear, the lowest gear is kept.
If the current indoor temperature is higher than the set temperature (that is, the air conditioner indoor unit has not reached the refrigeration effect preset by the user), the air supply gear of the air conditioner indoor unit is reduced, for example, the air supply gear of the air conditioner indoor unit is reduced by one gear.
According to the above, in the operation process of the air conditioner internal unit, the second image of the designated part of the user is collected at preset time intervals, and whether the body of the user is dry or not is determined by comparing the first image with the second image, namely, the drying state of the body of the user is monitored in real time.
When the first image and the second image are compared for two times continuously to determine that the body of the user is dry, the air supply gear (a refrigeration gear or a dehumidification gear) of an air conditioner indoor unit is lowered to the lowest gear, the air deflector and the swing blade are adjusted to the vertical uppermost position, and the user is reminded of needing to supplement moisture in the appointed APP.
When the operation mode of the air conditioner indoor unit is heating, the mode of controlling the air conditioner indoor unit is as follows:
if the current indoor temperature is lower than the set temperature of the air conditioner indoor unit (namely, the air conditioner indoor unit does not reach the heating effect preset by the user), the set temperature is adjusted to the current indoor temperature, and the humidification function of the air conditioner indoor unit is started, for example, the humidification function is started by sending a corresponding instruction to the air conditioner indoor unit through a designated APP.
Preferably, if a humidifier in communication connection with the designated APP exists indoors, the humidifier is opened through the designated APP, and the humidifying function of the air conditioner indoor unit may not be started at this time.
It can be understood that after the humidifying function is started or the humidifier is turned on, the second image of the designated part of the user is continuously acquired, and the drying state of the body of the user is continuously monitored in real time, that is, the step S102 is returned to be executed until the first image and the newly acquired second image are compared to determine that the body of the user is not dried, and the humidifying function or the humidifier is turned off.
And if the current indoor temperature is greater than or equal to the set temperature of the air conditioner indoor unit (namely the air conditioner indoor unit achieves the heating effect preset by a user), controlling the air conditioner indoor unit to stop running.
Step S105: and if the body drying change information indicates that the body of the user is not dried, keeping the current running state of the air conditioner indoor unit.
In the process of specifically implementing step S105, if it is determined that the body of the user is not dry through the body drying change information, the current operation state of the air conditioner internal unit is maintained, the second image of the designated part of the user is continuously acquired, the drying state of the body of the user is continuously monitored in real time, the air conditioner internal unit is correspondingly controlled, and the process returns to execute step S102.
In the embodiment of the invention, a first image of a part appointed by a user is obtained when an air conditioner indoor unit is started, and a second image of the appointed part is obtained at preset time intervals in the operation process of the air conditioner indoor unit. Whether the body of the user becomes dry or not is determined by comparing the first image with the second image, if the body becomes dry, the operation of the air conditioner indoor unit is controlled according to the current indoor temperature and the current operation parameters of the air conditioner indoor unit, so that the indoor humidity is adjusted, the operation of the air conditioner indoor unit is not required to be manually controlled by the user, the time of the user is saved, and the use experience of the user is improved.
In the above embodiment of the present invention, referring to fig. 2, the determination of the body dryness change information of the user in step S103 in fig. 1 is related to determining that the specified portion is a lip, and the flow chart for determining the body dryness change information provided in the embodiment of the present invention is shown, and includes the following steps:
step S201: and comparing the lip crack depths in the first image and the second image.
It can be understood that the specified portion is a lip, the first image and the second image both include information related to the lip of the user, and in the process of the specific implementation step S201, the first image is analyzed to obtain corresponding information including a lip crack depth, and the second image is analyzed to obtain corresponding information including a lip crack depth.
The change in the crack depth of the lips may reflect a change in the body dryness of the user, and when the crack depth of the lips of the user becomes deeper, it indicates that the body of the user becomes dry.
Therefore, the lip crack depths of the first image and the second image are compared, and whether the body of the user is dry or not is determined through the comparison result.
Step S202: if the lip crack depth in the first image is shallower than the lip crack depth in the second image, it is determined that the body dryness change information of the user indicates that the body of the user is dry.
In the process of implementing step S202 specifically, if the lip crack depth in the first image is shallower than the lip crack depth in the second image, that is, the lip crack depth of the user becomes deeper during the operation of the air conditioner, it is determined that the body dryness change information of the user indicates that the body of the user becomes dry.
Step S203: if the lip crack depth in the first image is deeper than the lip crack depth in the second image or there is no change, it is determined that the body dryness change information indicates that the user's body is not dry.
In the process of implementing step S202 specifically, if the depth of the lip crack in the first image is deeper than or does not change from the depth of the lip crack in the second image, that is, the depth of the lip crack of the user becomes shallower or does not change during the operation of the air conditioner, it is determined that the body dryness change information of the user indicates that the body of the user is not dry.
In the above steps S201 to S203, it is determined whether the user 'S body is dry by determining whether the user' S lips have a deep crack.
Accordingly, it may also be determined whether the user's body is dry by determining the change in the number and length of the fine lines of the user's lips.
When the user's body becomes dry, the number of fine lines of the lips becomes small and the length of the fine lines becomes short (the fine lines are broken due to lack of water), that is, when the human body is in a dry state, the number of fine lines of the lips is small and the length of the fine lines is short.
When the body of the user is not dry, the number of the fine lines of the lips is not reduced, and the length of the fine lines is not reduced, that is, when the human body is in a wet state, the number of the fine lines of the lips is larger, and the length of the fine lines is longer (the human body is wet, so that the extensibility of the fine lines is higher).
Specifically, how to determine whether the body of the user is dry by comparing the number of fine lines and the length of the fine lines in the first image and the second image can be referred to the contents of the above steps S201 to S203, and details are not repeated herein.
In an embodiment of the present invention, it is determined whether the body of the user is dry by comparing the lip crack depths in the first image and the second image. If the body of the user is determined to be dry, the air conditioner internal unit is controlled to operate according to the current indoor temperature and the current operation parameters of the air conditioner internal unit, so that the indoor humidity is adjusted, the air conditioner internal unit does not need to be manually controlled to operate by the user, the time of the user is saved, and the use experience of the user is improved.
In the above embodiment of the present invention, fig. 1, step S103, relates to determining body dryness change information of a user, where a designated part is a designated facial area, and referring to fig. 3, there is shown another flowchart for determining body dryness change information according to the embodiment of the present invention, including the following steps:
step S301: and respectively comparing the number of fine lines and the width of the fine lines of the designated face area in the first image and the second image.
It is understood that the designated part is a designated facial region, and the designated facial region can be set according to actual requirements, such as the designated facial region is a cheek.
In the specific implementation step S301, the first image is analyzed to obtain information including the number of fine lines (fine lines of the designated face region) and the width of the fine lines, and the second image is analyzed to obtain information including the number of fine lines and the width of the fine lines.
It should be noted that, when the human body is in a dry state, the number of fine lines in the designated face area is small and the fine line width is thick, and when the human body is in a wet state, the number of fine lines in the designated face area is large and the fine line width is thin, that is, the change of the number of fine lines and the fine line width in the designated face area can reflect the body drying change of the user, and when the number of fine lines in the designated face area of the user is small and the fine line width is thick, it indicates that the body of the user is dry.
Therefore, the number of fine lines in the first image and the second image are compared, and whether the body of the user is dry or not is determined through the comparison result by comparing the widths of the fine lines in the first image and the second image.
Step S302: and if the number of the fine lines in the first image is more than that in the second image, and the width of the fine lines in the first image is thinner than that in the second image, determining that the body dryness change information of the user indicates that the body of the user is dry.
In the process of implementing step S302 specifically, if the number of fine lines in the first image is greater than the number of fine lines in the second image, and the width of the fine lines in the first image is smaller than the width of the fine lines in the second image, that is, the number of fine lines in the designated face area of the user becomes smaller and the width of the fine lines becomes thicker during the operation of the air conditioner, it is determined that the body dryness change information of the user indicates that the body of the user becomes dry.
Step S303: and if the number of the fine lines in the first image is less than or has no change than the number of the fine lines in the second image, and the width of the fine lines in the first image is thicker than or has no change than the width of the fine lines in the second image, determining that the body dryness change information indicates that the body of the user is not dry.
