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. It is to be understood that the embodiments described are only a few embodiments of the present application and not all 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.
The display screen may be used for interaction between a user and the refrigerator, and the user may control the refrigerator through the display screen, for example, adjust an internal temperature of the refrigerator, change an ice making amount of the refrigerator, and control the refrigerator to perform self-cleaning. The display screen can also play videos, play music, monitor the inside of the refrigerator and the like. Therefore, the display screen plays a very important role in the process of realizing the intellectualization of the refrigerator. In the related art, the display screen runs continuously after being started up for most of time, and the power consumption is large. In addition, due to long-term use, the service life of the display screen is usually 2 to 3 years, which is far lower than the service life of the refrigerator (about 10 years). Therefore, when the newly-added display screen brings more visual experience to the client, the whole power consumption of the refrigerator is also improved, and the problems that the service life of the display screen is not matched with the service life of the refrigerator and the like exist.
Referring to fig. 1, fig. 1 is a control method for a display screen of a refrigerator according to an embodiment of the present application, including:
100. it is detected whether the display screen is in use.
Generally, when a user uses the display screen, the display screen is in a bright screen state. If a user touches the display screen to complete interaction with the refrigerator, the display screen is in the using process when the user plays videos or music and the like by using the display screen, and the display screen needs to be kept in a bright screen state all the time. However, when the display screen is not used, for example, when the user has not interacted with the refrigerator at present, and the music or video has been played, the display screen is still in a bright screen state at the moment. It can be understood that when the display screen is in the bright screen state but is not used, if the display screen needs to be continuously used next, the display screen needs to be controlled to keep the bright screen state for the user to continuously use. If the next time display screen is not used, the display screen can be extinguished to save power. Therefore, when the display screen is in a bright state, it is required to first detect whether the display screen is in use.
In the related art, in order to reduce power consumption of a display screen, a refrigerator is generally provided with a sleep time. When the screen-on duration of the unused display screen exceeds the sleep time, the display screen can automatically turn off. Namely, the unused time of the display screen exceeds the preset time, and the display screen automatically turns off to enter the standby mode to save the electric energy. However, if the set sleep time is too short, the user still has an intention to use the display screen (for example, the user pauses for a long time in the interaction process and continues to use the display screen after pausing), and the user can be influenced to use the display screen by timing screen refreshing (for example, the user wants to continue to use the display screen after pausing, but the display screen suddenly refreshes by timing screen refreshing), and it can be understood that the state is the wrong closing of the display screen. If the set sleep time is too long, the user leaves, and the display screen is always on in the sleep time period, which causes waste of electric energy.
200. If the display screen is not used, whether an object moves in a first preset range or not is detected, whether a human is in a second preset range or not is detected, and the second preset range is located in the first preset range.
In order to avoid the error closing of the display screen while saving power, the refrigerator needs to judge whether the user needs to use the display screen next. According to the demand of a user, whether the display screen is continuously on or off is controlled, so that the display screen can be effectively prevented from being turned off by mistake on the premise of saving electric energy.
It will be appreciated that if the user has a desire to use the display screen, it will typically move within a range, such as by walking or a change in body posture, where a change in body posture produces a greater change in position and a lesser change in body posture. The device for monitoring the movement of the object generally has high detection accuracy, and can detect small movement of the object. And when the user has the requirement of using the display screen, the user can not move around. Therefore, whether an object moves within a certain range is detected, and the detection can be used as an important basis for judging whether the user has a use requirement.
In addition, although whether an object moves within a certain range can be used as a basis for judging user requirements, along with popularization of smart homes, various robots capable of moving freely can also appear within a preset range. The environment of the refrigerator is not a single use scene, but is a very complex environment, such as a pet may pass through the first preset range, or the user only passes through the first preset range, but has no use intention. These all cause the refrigerator to detect that there is an object moving within the preset range, so if only detecting whether there is an object moving within the preset range is taken as a judgment basis, more erroneous judgment may be caused. Therefore, on the basis of detecting whether an object moves within the preset range, it is necessary to further determine whether the moving object is a human or not.
Whether an object moves within a first preset range or not can be detected, and whether a human is within a second preset range or not can be detected, wherein the second preset range is located within the first preset range. It should be noted that the first preset range and the second preset range both use the display screen as a center, and the second preset range is closer to the display screen. Detecting whether a human is present in a smaller area may confirm, on the one hand, that the user is in front of the display screen (rather than a pet or other mobile machine), and on the other hand, that the user is further away from the display screen.
300. If the object is detected to move in the first preset range and a human is detected to move in the second preset range, controlling the display screen to continuously light; otherwise, controlling the display screen to display information.
It will be appreciated that the closer the user is to the display station, the more likely it is that the user will use the display. If an object moves within a first preset range and a human is within a second preset range, the user can be determined to be positioned in front of the display screen. At this time, the user has a large probability of having a need to use the display screen, and thus it can be judged that the user has a need to use the display screen.
It should be noted that if no object moves within the first preset range, no human is detected within the second preset range, so that the user can control the display screen if it is determined that the user does not need to use the display screen before the user leaves the display screen. If an object moves within the first preset range but a human is not detected within the second preset range, it indicates that the user is far away from the display screen and the user may simply pass through the refrigerator (the refrigerator may be disposed in a narrow space and the user may pass through a place relatively close to the refrigerator). At this time, the user can be judged that the user does not use the display screen, and then the display screen information screen is controlled.
In the embodiment of the application, when the display screen is in a bright screen state but is not used, the refrigerator needs to judge whether a user has a requirement for using the display screen, and judge when to turn off the screen according to the requirement of the user. If it is detected that an object moves within the first preset range, a human being is within the second preset range, and therefore the user can be judged to be positioned at a position close to the display screen. That is, although the display screen is not used, the user still has a need to use the display screen, and the use of the display screen is not finished, in this case, the display screen is controlled to be continuously lightened. Otherwise, the user is far away from the refrigerator, the user does not operate the display screen after the user finishes using the refrigerator, and the display screen is controlled. Compare in correlation technique, come regularly to extinguish the display screen through setting up dormancy time, this application embodiment has carried out the judgement to user's demand, when the user does not use the demand of display screen, can in time extinguish the display screen in order to practice thrift the electric energy. When the user has the intention to use the display screen, the display screen cannot be closed by mistake. The display screen can be prevented from being turned off by mistake while the power is saved, the control efficiency is improved, and the misoperation is avoided.
It should be noted that, in step 200, the refrigerator may detect the first preset range and the second preset range simultaneously, that is, detect whether there is a human being in the second preset range while detecting whether there is an object moving in the first preset range. Of course, in step 200, the first preset range and the second preset range may be detected sequentially. Referring to fig. 2, fig. 2 is a second method for controlling a display screen of a refrigerator according to an embodiment of the present application, which includes:
210. and if the display screen is not used, detecting whether an object moves within a first preset range.
220. If the object moves within the first preset range, detecting whether the object is located within a second preset range;
it will be appreciated that the second predetermined range lies within the first predetermined range. When the object moves within the first predetermined range, the object may or may not be located within the second predetermined range. Therefore, the position of the object needs to be further determined, that is, whether the object is located within the second preset range is detected, so as to determine whether the object is further close to the display screen.
230. And if the object is located in the second preset range, detecting whether the object is a human or not.
It should be noted that, the characteristics of the object may be obtained first, and whether the object is a human or not may be determined according to the characteristics of the object, and for example, the heartbeat, the facial characteristics, the body surface temperature, and the like may be used as the determination basis.
For example, the detecting whether there is a human being within the second preset range may further include: and detecting whether the heart rate is detected within a second preset range. It can be understood that if the moving robot is in the second preset range, although it can be detected that the object moves within the first preset range, the heart rate cannot be detected within the second preset range. Whether the object is a human can be judged by the heart rate to reduce misjudgment. It should be noted that, if the heart rate is detected, whether the heart rate value is within a preset range is detected. The heart rate of a human is generally 60 to 100 times per minute. If not, judging that no human exists in the second preset range; if yes, judging that the human being exists in the second preset range. For example, the refrigerator can emit microwaves to detect whether a heartbeat exists within a second preset range, and other manners may be adopted to obtain a heartbeat value of the object, which is not limited herein.
Of course, the characteristics of the object may also be obtained by other means, such as obtaining facial characteristics of the object by image recognition, obtaining body surface temperature of the object by an infrared device, and the like, and the method for obtaining the characteristics is not limited herein.
In order to ensure the accuracy of the detection, the intention of the user can be secondarily judged. Referring to fig. 3, fig. 3 is a third method for controlling a display screen of a refrigerator according to an embodiment of the present application. If it is detected that an object moves within the first preset range and a human is within the second preset range, controlling the display screen to continuously light up, and then, the control method may further include:
312. detecting whether the display screen is in use;
313. and if the time length of the display screen which is not used exceeds the preset time length, controlling the display screen to display information.
For example, the preset time period may be 3 minutes. It will be appreciated that the user may not have a need to use the display screen even if the user stands in front of the display screen, even if the user moves within the first predetermined range. When the display screen is not used, the display screen is kept bright all the time, and the waste of electric energy is still caused. The situation can be solved by secondary judgment, and if the time length of the display screen which is not used exceeds the preset time length, the display screen is timely extinguished to save electric energy.
It can be understood that the electric energy can be saved by extinguishing the display screen in time, and after the display screen is extinguished, the display screen needs to be awakened in time when the user needs to use the display screen again. Referring to fig. 4, fig. 4 is a flowchart illustrating a fourth method for controlling a display screen of a refrigerator according to an embodiment of the present application, where after controlling the display screen, the method may further include:
322. whether an object moves within a first preset range is detected.
It can be understood that when the user needs to use the display screen, the user gradually approaches the display screen, and the first preset range is centered on the display screen. In the approach process of the user, the user enters a first preset range and moves in the first preset range.
323. And if the object moves in the first preset range, detecting whether the object is in a second preset range.
The second preset range is located in the first preset range, and the second preset range is closer to the display screen. And detecting whether the object reaches a second preset range, and further determining that the user has the intention of using the display screen.
324. And if the object is within the second preset range, detecting whether the object is a human or not.
To reduce false positives on moving robots, pets, or other situations, it may be detected whether the object is a human. It can be understood that if the object is not within the second preset range, the method partially determines whether the object is a human being, and directly determines that the display screen is not used next.
325. And if the object is a human, controlling the display screen to light.
It will be appreciated that if the object is not a human, the display continues to remain off.
It should be noted that other ways may also be adopted to wake up the display screen, for example, wake up in the form of human body sensing scene, touch screen operation, UART (Universal Asynchronous Receiver and Transmitter, Asynchronous serial communication port) connection, WIFI communication, or RTC (Real-Time Clock), and the like, which is not limited herein. However, in order to put the electronic display screen in a sleep state as much as possible, the wake-up source may be reduced. The display screen wake-up scene may include at least one of human body sensing, touch screen operation, and refrigerator opening/closing operation, i.e., directly waking up the display screen. And the awakening source is reduced, the starting time of the electronic display screen can be reduced, and the power consumption is reduced.
It should be noted that the refrigerator in the embodiment of the present application can emit microwaves and detect whether an object moves within a first preset range by using a doppler principle, and certainly, other principles may be used to detect the movement of the object.
Referring to fig. 5 and 6, fig. 5 is a schematic structural diagram of a refrigerator according to an embodiment of the present application, and fig. 6 is a schematic connection diagram of modules in fig. 5. The refrigerator 400 may be a double-door refrigerator, or may be a single-door refrigerator or a triple-door refrigerator, which is not limited herein. Refrigerator 400 includes door 1, box 2, display screen 3, removal perception module 4, identification module 5 and control module 6, and display screen 3 sets up on door 1, and identification module 5 and removal perception module 4 all set up on box 2.
Referring to fig. 6, the motion sensing module 4 is used to detect whether an object moves within a first preset range, and the recognition module 5 is used to detect whether a human being is within a second preset range. Control module 6 is connected and control with display screen 3 electricity show 3 bright screen or rest the screen, control module 6 with remove perception module 4 with identification module 5 electricity is connected, if it has the object to move to remove perception module 4 and detect first preset within range, and identification module 5 discerns have the human in the second preset within range, then control module 6 control display screen 3 continues bright screen, otherwise control display screen 3 rests the screen.
It should be noted that, the mobile sensing module 4 and the recognition module 5 may work simultaneously, that is, the mobile sensing module 4 detects whether there is an object moving within the first preset range, and the recognition module 5 detects whether there is a human being within the second preset range. Of course, the working sequence of the two may also be in sequence, and the identification module 5 may detect whether there is a human being in the second preset range after the movement sensing module 4 detects that there is an object moving in the first preset range. When the mobile sensing module 4 detects, the recognition module 5 does not work, so that electric energy can be saved.
It should be noted that the movement sensing module 4 can emit microwaves and detect whether an object moves within a first preset range by using a doppler principle, and the movement sensing module 4 can also detect the movement of the object by using other principles, which is not limited herein. The recognition module 5 may also detect the heart rate of the object by using microwaves, and certainly, the recognition module 5 may also be an image recognition device that determines whether the object is a human by recognizing the external characteristics of the object, or an infrared device that determines whether the object is a human by detecting the body surface temperature of the object. And are not limited herein.
The detection range of the movement perception module 4 may be greater than or equal to a first preset range, for example, the first range may be an area 3 meters in front of the display screen. The detection range of the recognition module 5 may be greater than or equal to a second preset range, which may be, for example, an area 1 meter in front of the display screen.
