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.
Referring to fig. 1 and 2, an embodiment of the present invention provides an air conditioner indoor unit for adjusting a temperature of an environment (e.g., a bedroom) where the air conditioner indoor unit is located. This air conditioner indoor unit includes lamp plate 100, photosensitive assembly 200 and controller 500, and lamp plate 100 and photosensitive assembly 200 communicate with controller 500 respectively, and photosensitive assembly 200 sets up on lamp plate 100 for obtain the light intensity of air conditioner indoor unit place environment, and controller 500 is configured as the display state according to light intensity control lamp plate 100.
This air conditioner indoor unit can control the display state of lamp plate 100 and change along with the change of the light intensity of air conditioner indoor unit place environment, and when satisfying certain condition, lamp plate 100 can not show or energy-conserving demonstration, and is not in the normal bright state and luminance unchangeable all the time, just so can effectively reduce the energy consumption of air conditioner.
Further, the air conditioner indoor unit further comprises a camera module 300 and a sound-sensitive module 400, the camera module 300 and the sound-sensitive module 400 are both arranged on the lamp panel 100, and the camera module 300 and the sound-sensitive module 400 are respectively communicated with the controller 500. The camera assembly 300 is used for acquiring behaviors of a user, and the sound sensitive assembly 400 is used for acquiring sound intensity of the environment where an air conditioner indoor unit is located; the controller 500 is configured to control the display state of the lamp panel 100 according to the light intensity and the behavior of the user or control the display state of the lamp panel 100 according to the light intensity, the behavior of the user, and the sound intensity.
The display state of the lamp panel 100 is controlled according to the light intensity of the environment where the air conditioner indoor unit is located and the behavior of the user and the sound intensity of the environment where the air conditioner indoor unit is located, so that the normal use of the air conditioner is guaranteed while the energy consumption of the air conditioner is reduced, and the influence on the user experience is avoided. Meanwhile, due to the introduction of various control conditions, the lamp panel display method can be richer so as to adapt to different conditions and scenes.
The working principle, the process and the obtained technical effects of the air conditioner internal unit are as follows:
the light sensitive component 200 detects the light intensity in the environment where the air conditioner indoor unit is located in real time and sends the light intensity to the controller 500, the sound sensitive component 400 detects the sound intensity in the environment where the air conditioner indoor unit is located in real time and sends the sound intensity to the controller 500, and the camera component 300 collects the behavior of a user in real time and sends the behavior to the controller 500;
when the light intensity monitored by the photosensitive component 200 is greater than or equal to the first threshold value, the display mode of the lamp panel is the daytime mode. In the daytime mode, when the camera module 300 captures that the user looks at the air conditioner internal unit, the controller 500 controls the lamp panel 100 to normally display. When the camera module 300 captures that the user does not look at the air conditioner, the controller 500 controls the lamp panel 100 not to display or to display energy-saving. Under the daytime mode, if the user sees the air conditioner indoor unit, it shows that the user has probably to observe or adjust the demand of air conditioner operating mode, and normal work that can guarantee the air conditioner is normally shown to lamp plate 100 this moment to satisfy user's demand. And if the user does not look at the air conditioner indoor unit, it is very likely that the user does not observe or adjust the requirement of the working condition of the air conditioner, and at the moment, the lamp panel 100 does not display or displays energy-saving, so that the energy consumption of the air conditioner can be effectively reduced.
When the light intensity detected by the photosensitive component 200 is less than the first threshold, the lamp panel display mode is the night mode. In the night mode, when the camera module 300 collects that the user is moving, the controller 500 controls the lamp panel 100 to normally display; when the camera assembly 300 collects that the user is not moving, but the sound intensity detected by the sound sensitive assembly 400 is greater than or equal to the third threshold, the controller 500 controls the lamp panel 100 to save energy for display; when the camera assembly 300 collects that the user is not moving and the sound intensity detected by the sound sensitive assembly 400 is less than the third threshold, the controller 500 controls the lamp panel 100 not to display.
In the night mode, if the user is moving, it indicates that the user does not have a rest or fall asleep, and at this time, the normal display of the lamp panel 100 is controlled to ensure the normal use of the air conditioner, so as to meet the requirements of the user. If the user is not moving, but the sound intensity is greater than or equal to the third threshold, it indicates that the user is most likely preparing to rest or fall asleep, but does not have a complete rest or fall asleep yet, and at this time, the lamp panel 100 is energy-saving to display, so that on one hand, the energy consumption of the air conditioner can be reduced, and on the other hand, the influence of the light of the lamp panel 100 on the user can be reduced. If the user does not move, and the sound intensity is less than the third threshold value, it indicates that the user has a rest or falls asleep very probably, and at this time, the lamp panel 100 does not display, so that not only can the energy consumption of the air conditioner be effectively reduced, but also the influence of the light of the lamp panel 100 on the rest or sleep of the user can be avoided.
In conclusion, the air conditioner indoor unit can reduce the internal consumption of the air conditioner as much as possible on the premise of ensuring normal use and meeting the requirements of users, and meanwhile, the influence on the rest or sleep of the users is avoided.
Finally, it should be noted that the air conditioner internal unit may be an internal unit of a wall-mounted air conditioner, or an internal unit of a cabinet air conditioner.
Referring to fig. 3, an embodiment of the invention provides a lamp panel display method, which can be applied to a controller 500 of an air conditioner internal unit. The lamp panel display method comprises the following steps:
step S100: and acquiring the light intensity of the environment where the air conditioner indoor unit is located. When the air conditioner works, the photosensitive assembly 200 can detect the light intensity of the environment where the air conditioner indoor unit is located in real time and send the light intensity to the controller 500.
Step S200: the display state of the lamp panel 100 is adjusted according to the light intensity. After the controller 500 receives the light intensity of the environment where the air conditioner indoor unit is located, the display state of the lamp panel 100 can be controlled accordingly.
Referring to fig. 4, in the present embodiment, the step of adjusting the display state of the lamp panel 100 according to the light intensity includes:
when the light intensity is greater than or equal to the first threshold, step S300 is performed: and judging whether the user looks at the air conditioner indoor unit.
In detail, the first threshold may be preset by a manufacturer of the air conditioner, or may be set by a user according to a requirement of the user in the process of using the air conditioner, so as to meet an individual requirement.
Referring to fig. 5, in the present embodiment, the step of determining whether the user looks at the air conditioner internal unit includes:
step S310: an image of the user's face is acquired. The camera assembly 300 captures a facial image of the user and transmits it to the controller 500.
Step S320: the face image is segmented using the Grabcut algorithm. The Grabcut algorithm is an existing image segmentation algorithm, and a program for implementing the Grabcut algorithm is built in the controller 500. When the controller 500 receives the face image of the user, the face image of the user is segmented using the Grabcut algorithm.
Step S330: and extracting feature points of the face image and the geometric position relation between the feature points by using a haarcacades classifier so as to judge whether the front face of the user faces towards the air conditioner indoor unit. The haarcacades classifier is an existing image processing algorithm, and a program for implementing the haarcacades classifier is built in the controller 500. After the controller 500 performs segmentation processing on the face image, the segmented face image is processed by using the haarcacades classifier to determine whether the user faces the air conditioner indoor unit. The haarcacades classifier mainly uses priori knowledge to regard the human face as a combination of organ features, and detects the human face according to the features of organs such as eyes, eyebrows, mouth, nose and the like and the geometric position relation among the organs. The face collected by the algorithm is a front face, when a user leans to the side or the face is shielded, the user can be regarded as a non-front face facing air conditioner, and a plurality of face images can be collected simultaneously by the method.
Step S340: and judging whether the user looks at the air conditioner indoor unit according to whether the user faces the air conditioner indoor unit. Referring to fig. 6, in this embodiment, the step of determining whether the user looks at the air conditioner indoor unit according to whether the user is facing the air conditioner indoor unit includes:
when the user is not facing the air conditioner indoor unit, step S350 is performed: and judging that the user does not look at the air conditioner indoor unit.
When the user faces the air conditioner indoor unit, step S360 is executed: a haarcascade _ eye classifier is used to determine if the user's face has open eyes. When the user' S face has their eyes open, step S362 is performed: and judging that the user looks at the air conditioner indoor unit. When the user' S face has no open eyes, step S350 is performed: and judging that the user does not look at the air conditioner indoor unit.
When the user faces the air conditioner indoor unit, the representative user does not look at the air conditioner indoor unit, so that the fact that the user does not look at the air conditioner indoor unit can be directly judged. However, when the user faces the air conditioner indoor unit, the user does not necessarily look at the air conditioner indoor unit, for example, the user may be resting close to eyes, but just faces the air conditioner indoor unit. Therefore, when the user faces the air conditioner indoor unit, a step of judging whether the user's face has open eyes is added. The haarcascade _ eye classifier is an existing image processing algorithm, and is implemented within the program and controller 500. When the controller 500 determines that the user faces the indoor unit of the air conditioner, the haarcascade _ eye classifier is further used to determine whether the user faces the eyes open, so as to ensure the accuracy of determining whether the user looks at the indoor unit of the air conditioner.
Referring to fig. 4 again, after step S300, the step of adjusting the display state of the lamp panel 100 according to the light intensity further includes step S400: the display state of the lamp panel 100 is controlled according to whether the user looks at the air conditioner indoor unit.
Whether the user sees to the air conditioner, whether the representative user has the operating mode that needs to the air conditioner to observe or adjust, whether see to the air conditioner according to the user and come to control the display state of lamp plate 100 can effectively facilitate the user to the use of air conditioner, guarantee that the air conditioner carries out work according to user's expectation, effectively avoid influencing user experience.
Referring to fig. 7, in the present embodiment, the step of controlling the display state of the lamp panel 100 according to whether the user looks at the air conditioner internal unit includes:
when the user looks at the air conditioner internal unit, step S410 is executed: the control lamp panel 100 displays normally.
When the user looked at the air conditioner internal unit, the representative user probably has the demand of observing or adjusting the operating mode of air conditioner, and control lamp plate 100 normally shows this moment, can guarantee that the user can in time clearly observe the operating mode of air conditioner to carry out relevant regulation, satisfy self demand.
Further, the time of the normal display is the preset time, and if the user continuously looks at the air conditioner indoor unit, the time of the normal display is continuously reset to the preset time. That is, when the user looks at the air conditioner indoor unit, the lamp panel 100 displays normally and lasts for a preset time. The preset time can be preset by a manufacturer of the air conditioner, and can also be set by a user according to the requirement of the user so as to meet the personalized requirement. When the user no longer looks at the air conditioner internal unit, that is, when the line of sight is moved from the air conditioner internal unit to another place, the lamp panel 100 does not immediately change the normal display state, but continues normal display within the preset time. After a preset time, the lamp panel 100 may change the display state. The aim at that sets up like this if the user in the time of predetermineeing after no longer looking the air conditioner internal unit, when looking at the air conditioner internal unit again, can directly see the operating mode parameter etc. of the air conditioner of normal demonstration, and can not have the delay, also can avoid lamp plate 100 frequent change display state in the short time simultaneously. Of course, if the user continuously looks at the air conditioner internal unit, the lamp panel 100 will not change the normal display state after the preset time, because the preset time is continuously reset, and this makes the lamp panel 100 continuously display normally.
When the user does not look at the air conditioner internal unit, step S420 is executed: the control light panel 100 does not display or displays energy-saving. The above-mentioned "power saving display" means that power consumption is lower than that of normal display, and for example, the display may be performed at a lower brightness than that of normal display, or the display content may be reduced.
When the user does not look at the air conditioner indoor unit, it is very likely that the user does not have the demand of observing or adjusting the operating mode of air conditioner, and control lamp plate 100 does not show or energy-conserving demonstration this moment, just can effectively reduce the energy consumption of air conditioner, and can not influence user experience.
Referring to fig. 3 again, in this embodiment, the step of adjusting the display state of the lamp panel 100 according to the light intensity further includes:
when the light intensity is lower than the first threshold, step S500 is performed: it is determined whether the user is in motion.
Referring to fig. 8, in the present embodiment, the step of determining whether the user is moving includes:
step S510: and acquiring an image of the user and carrying out binarization processing to obtain an area where the user is located. The camera module 300 captures an image of a user and transmits the image to the controller 500. The image binarization processing is an existing image processing algorithm, and a program for realizing the image binarization processing is built in the controller 500. After the controller 500 receives the image of the user, the controller 500 performs binarization processing on the image by using the above program to obtain the area where the user is located.
Step S520: and calculating the center of the area where the user is located by utilizing a gray scale gravity center method. The gray scale gravity center method takes the gray scale value of each pixel point in the area where the user is located as the 'quality' of the point, and the calculation formula of the center of the area where the user is located is as follows:
wherein f (u, v) is the gray value of the pixel point with the coordinate (u, v); (u, v) coordinates of all positions of the area where the user is located;the coordinates of the center position of the area where the user is located.
Step S530: the moving speed of the center is acquired. The controller 500 may compare the difference between the two pictures before and after the moving of the center in the unit time to obtain the moving speed of the center.
When the moving speed of the center is greater than or equal to the second threshold, step S532 is performed: and judging that the user is moving. When the moving speed of the center is less than the second threshold, step S534 is performed: it is determined that the user is not moving. The second threshold value can be preset by the manufacturer of the air conditioner, or can be set by the user according to the need of the user in the process of using the air conditioner, so as to meet the personalized requirements.
Referring to fig. 3 again, after step S500, the step of adjusting the display state of the lamp panel 100 according to the light intensity further includes step S600: the display state of the lamp panel 100 is controlled according to whether the user is in the motion.
Referring to fig. 9, in the present embodiment, the step of controlling the display state of the lamp panel 100 according to whether the user is in the motion includes:
when the user is in motion, step S410 is performed: the control lamp panel 100 displays normally. When the user is moving, it indicates that the user does not have a rest or fall asleep, and control lamp plate 100 normally shows this moment, can guarantee that the user can clearly observe the operating mode of air conditioner to adjust according to self needs.
When the user has no motion, step S610 is performed: acquiring the sound intensity of the environment where an air conditioner indoor unit is located; and step S620: the display state of the lamp panel 100 is controlled according to the sound intensity.
In this embodiment, the step of controlling the display state of the lamp panel 100 according to the sound intensity includes:
when the sound intensity is greater than or equal to the third threshold, step S622 is performed: the control light panel 100 can save energy for display. When the sound intensity is less than the third threshold, step S624 is performed: the control light panel 100 does not display. The third threshold value can be preset by the manufacturer of the air conditioner, or can be set by the user according to the need of the user in the process of using the air conditioner, so as to meet the personalized requirements.
