Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In a first aspect, the present application provides an intelligent home device, which may be a home device with a display function, as shown in fig. 1, taking an intelligent refrigerator with a display function as an example, the refrigerator includes a housing 100, a door 110, and a display screen 120.
The door 110 is disposed on the casing 100, a refrigerating chamber and a freezing chamber are disposed inside the door 110, and a display screen 120 is disposed outside the door 110. Display screen 120 is connectable a controller, shows according to the control of controller, and this controller can carry on operating system, like android operating system, can network and run application, like menu class APP, video class APP, music class APP, clock class APP etc.. The controller can also be connected with a voice recognition module device to realize voice control. The controller can also be connected with a loudspeaker to realize the sound playing function. Certainly, the controller can also be connected with other equipment to enrich the functions of the intelligent refrigerator, and the functions are not listed one by one in the embodiment.
The smart refrigerator may be installed in a user's kitchen and the user may interact with the smart refrigerator via the display screen 120, e.g., when the user is ready to cook, a recipe may be queried on the display screen 120; in the cooking process of the user, the user can open the video and match with the APP or the music APP on the display screen 120, while cooking, the user can watch the video or listen to music, the user can also open the clock APP on the display screen 120 for timing, the user can be reminded to finish cooking after the timing time is up, for example, when the user cooks bone soup, the user can be timed for 1 hour, and after the timing is finished, the intelligent refrigerator plays the ringtone to remind the user of extinguishing the fire source of the gas stove. In addition, the user can also install shopping software on the controller connected to the display screen 120 to purchase commodities such as fruits and vegetables through the display screen 120.
When a user is ready to cook or to cook, the user may need to interact with the intelligent refrigerator, and the time for interacting with the intelligent refrigerator in other time periods may be short, and in the process of ready to cook or to cook, the user needs to interact with the intelligent refrigerator and perform other things, such as food preparation and the like, so that the interaction between the user and the intelligent refrigerator may be intermittent, if the display screen 120 is set to be in a normally bright state to wait for the user to operate at any time, the power consumption is high, the service life of the display screen 120 is also shortened, if the display screen 120 is set to be in a standby state when the user does not receive a user operation command within a period of time (except a case that the display screen 120 is playing a video screen), when the user needs to interact with the display screen 120, the user wakes up the display screen 120 in a touch mode, a voice control mode and the like, so that the display screen 120 is bright for displaying, when the user stops interacting with the display screen 120 within a period of time in the process of ready to cook or to cook, the user restarts to wake up the display screen 120 again after a period of time, the user needs to wake up the display screen 120 again, and the user needs to experience for a certain time.
In order to solve the above problem, the present application is configured such that when a user is far away from the intelligent refrigerator, the intelligent refrigerator wakes up from a standby state, but does not display an image on the display screen 120, so as to reduce power consumption. As shown in fig. 2, when a user needs to interact with the intelligent refrigerator, the user may move to the intelligent refrigerator from a distance away from the intelligent refrigerator, and when the distance between the user and the intelligent refrigerator is D1, the intelligent refrigerator may be set to wake up from a standby state, where D1 may be set to 1 meter, and since the distance between the user and the intelligent refrigerator is far and the possibility of interacting with the intelligent refrigerator is low, the display screen 120 may be set to wake up but not display an image, so as to reduce power consumption. When the user is at a short distance from the smart refrigerator, the display screen 120 of the smart refrigerator displays images, which can interact with the user.
As shown in fig. 3, when the distance between the user and the intelligent refrigerator is D2, the display screen 120 of the intelligent refrigerator can be set to display an image, wherein D2 can be set to 0.5 meter, because the distance between the user and the intelligent refrigerator is relatively short, the possibility of interaction between the user and the intelligent refrigerator is relatively high, the display screen 120 can realize interaction with the user, and because the user and the intelligent refrigerator are at a distance D1 before, the display screen 120 starts to wake up, therefore, when the distance between the user and the intelligent refrigerator is D2, the intelligent refrigerator already wakes up, only the screen needs to be turned on, the user does not need to wait for the display screen 120 to wake up, and the user experience is improved.
In the foregoing embodiment, the display control method of the display screen 120 is described by taking the smart refrigerator as an example, and of course, other smart home devices with a display function, such as a smart door, a smart television, and the like, may also apply the display control method.
Referring to fig. 4, a schematic structural diagram of the smart home device shown in this embodiment is shown in fig. 4, where the controller controls the display screen 120 according to the principle that the distances between the user and the smart refrigerator are D1 and D2, and as shown in fig. 4, the smart home device includes the display screen 120, a controller 200, a first distance sensor 300, and a second distance sensor 400.
The first distance sensor 300 may be a long-distance sensor, and may detect a first distance from the smart home device, that is, an environment in D1, and generate a first signal, and the first distance sensor 300 may send the first signal to the controller 200, so that the controller 200 may analyze whether a human body is detected in the first distance from the smart home device, that is, in D1. The first distance is an effective detection distance of the first distance sensor 300 set by the controller 200, an actual detection distance of the first distance sensor 300 can be greater than or equal to the first distance, and the controller 200 can set the actual detection distance of the first distance sensor 300 to be less than or equal to the first distance according to human body detection requirements of the smart home devices.
In practical implementation, the first distance sensor 300 may be selected as a first infrared sensor, and the first infrared sensor may be a passive sensor, which has an advantage of long detection distance. The first infrared sensor can detect infrared rays in a first distance of the intelligent household equipment and generate a first signal, and the first signal can reflect the infrared ray intensity in the first distance of the intelligent household equipment. When the heat source is in the first distance of the intelligent household equipment, the infrared ray intensity is increased compared with the infrared ray intensity before the heat source is in the first distance. The human body is a heat source that can give off heat, and when the human body appeared in intelligent household equipment's first distance, the infrared ray intensity that first infrared sensor detected will strengthen, and other heat sources, like the pet appears in the house in the first distance of intelligent household equipment in, the infrared ray intensity that first infrared sensor detected will also rise, and whether the heat source that controller 200 can judge first infrared sensor according to the situation of change of first signal detected is the human body.
Certainly, first infrared sensor also can be active infrared sensor, initiatively launches the infrared ray promptly, if there is the object to be located intelligent household equipment the place ahead, then first infrared sensor will be received the infrared ray that reflects back through the object, according to the infrared ray generation second signal that reflects back. When different objects are located in front of the display screen 120, the reflected infrared ray intensities will be different, and the controller 200 can determine whether the object detected by the first infrared sensor is a human body according to the change condition of the first signal.
The second distance sensor 400 may be a short-distance sensor, which may detect a second distance of the smart home device, i.e., an environment within D2, and generate a second signal, wherein the second distance is smaller than the first distance. The second distance sensor 400 may transmit a second signal to the controller 200 for the controller 200 to analyze whether a human body is detected within a second distance from the smart home device. The second distance is an effective detection distance of the second distance sensor 400 provided by the controller 200. The actual detection distance of the second distance sensor 400 may be greater than or equal to the second distance, and the controller 200 may set the second distance to be less than or equal to the actual detection distance of the second distance sensor 400 according to the human body detection requirement of the smart home device.
In practical implementation, the second distance sensor 400 may be selected as a second infrared sensor, the second infrared sensor may be an active infrared sensor, and a signal generated by the second infrared sensor is referred to as a second signal, which can reflect whether an object is located in front of the display screen 120 within a second distance of the smart home device.
The display screen 120 may include a display panel 122 and a backlight module 121, the display panel 122 includes a display screen, the backlight module 121 includes a light source, the display panel 122 and the backlight module 121 are respectively connected to the controller 200, the display panel 122 may receive a display signal of the controller 200, output a corresponding image on the display screen according to the display signal, the backlight module 121 may receive a screen-on signal or a screen-off signal of the controller 200, light the light source according to the screen-on signal, and extinguish the light source according to the screen-off signal. When the backlight module 121 lights up the light source, the image displayed on the display panel 122 can be seen by the user; when the backlight module 121 turns off the light source, the image output on the display panel 122 cannot be seen by the user.
The controller 200 is electrically connected to the first distance sensor 300, the second distance sensor 400, and the display screen 120, respectively, and performs display control of the display screen 120 according to a first signal of the first distance sensor 300 and a second signal of the second distance sensor 400.
When the user needs to use the smart home device, the user may move to the front of the smart home device from a far distance from the smart home device, and when the user moves to a first distance of the smart home device, the first signal transmitted by the first distance sensor 300 to the controller 200 may be changed more greatly than when the user is located outside the first distance range of the smart home device, for example, the infrared ray intensity is significantly increased. The controller 200 may determine whether the first distance sensor 300 detects a human body according to the degree of the infrared intensity enhancement reflected by the first signal. If the controller 200 determines that the first distance sensor 300 detects a human body, it may enter an awake state and transmit a display signal to the display panel 122 of the display screen 120 according to that the current state is a standby state, and maintain the awake state and transmit a display signal to the display panel 122 of the display screen 120 according to that the current state is already an awake state (if the user may control the display device in a remote control manner); however, the backlight module 121 does not send the bright screen signal to the display screen 120, so that the display panel 122 outputs the image corresponding to the display signal in the screen saver state, at this time, the backlight module 121 does not light the light source, and the user cannot see the image output by the display panel 122.
When the user moves to a second distance of the smart home device, the second signal transmitted to the controller 200 by the second distance sensor 400 may be changed more greatly than when the user is out of the second distance range of the smart home device, for example, the strength of the second signal is significantly increased. The controller 200 may determine whether a human body is detected according to a degree of change of the second signal. If the controller 200 determines that the second distance sensor 400 detects a human body, it may maintain the awake state and transmit a display signal to the display panel 122 of the display screen 120 according to that the current state is already the awake state; and sends the screen-up signal to the backlight module 121 of the display screen 120, so that the backlight module 121 lights up the light source, thereby enabling the display panel 122 to output the image corresponding to the display signal in the screen-up state, and enabling the user to see the image displayed by the display panel 122. Because when the user moves to the first distance of the smart home device, the controller 200 already controls the display panel 122 to display the image, when the user moves to the second distance, the controller 200 only needs to control the backlight module 121 to light the light source, and for the user, the user does not need to wait for the smart home device to enter the wake-up state from the standby state to display the image, thereby improving the user experience.
To further explain the display control method of the smart home device, the embodiment provides a display control method of the smart home device in a second aspect, and as shown in fig. 5, the display control method of the smart home device includes the following steps:
step S110: whether a human body exists in the first distance of the intelligent household equipment is detected.
In this embodiment, adopt passive form infrared sensor as first distance sensor, gather the infrared ray in the first distance internal environment of intelligent household equipment through first distance sensor, generate first signal, send first signal to the controller.
According to the first signal, the distance of the intelligent household equipment can be obtained, if the infrared intensity in the first distance is obtained, when different heat sources appear in the first distance of the intelligent household equipment, the enhancement degree of the infrared intensity is different, and the infrared enhancement degree of the human body when the human body appears in the first distance of the intelligent household equipment can be determined in advance through a first contrast experiment. The experimental procedure for a first control experiment was as follows:
when no human body exists within a first distance of the intelligent household equipment, acquiring a first signal measured by a first distance sensor as a reference value; when a human body exists in the first distance of the intelligent household equipment, acquiring a first signal measured by a first distance sensor as a measured value, wherein when the measured value is calculated, a plurality of human bodies can stand in the first distance of the intelligent household equipment in sequence to obtain a plurality of first signals, and the weighted average value of the plurality of first signals is taken as the measured value; and obtaining a second threshold value corresponding to the reference value according to the measured value.
According to the experimental method, the determined second threshold value may be 1.6 times the reference value, that is, when the change of the first signal exceeds 60% of the reference value, it may be considered that the human body is detected within the first distance of the smart home device.
Because infrared ray intensity can change along with ambient temperature changes, consequently, at the different moments in a day, even no human body has always been in the first distance of smart home devices, first distance sensor's first signal also can produce the change. In order to improve the detection reliability of the first distance sensor, the reference value may be adjusted, and as shown in fig. 6, the method for adjusting the reference value may include steps S210 to S240.
Step S210: an average measurement of the first signal over the calibration period is calculated.
The initial value of the reference value can be stored in the controller of the intelligent household equipment, the controller can dynamically adjust the reference value after the intelligent household equipment is started, and according to actual requirements, the controller can adjust the reference value in real time or at intervals, or can adjust the reference value only once after the intelligent household equipment is started.
The correction period can be selected to be 2 seconds, all measured values of the first signal within 2 seconds are obtained, the average value of all measured values is calculated to obtain an average measured value, and the average measured value is used as the size of the first signal within the correction period.
Step S220: and judging whether the average measured value is less than or equal to a first threshold value corresponding to the reference value.
The first threshold may be 1.3 times the reference value, that is, when the change of the first signal is less than or equal to 30%, it may be considered that the change of the first signal is not caused by the human body appearing within the first distance of the smart home device, but may be caused by the change of the ambient temperature. The first threshold value can be adjusted according to actual conditions.
If the average measured value is greater than the first threshold corresponding to the reference value, the adjustment of the reference value may be terminated, and the process returns to step S210, and the average measured value is recalculated in the next calibration period.
Further, if the average measurement value is larger than a first threshold value corresponding to the reference value, whether the measurement value at the current moment is larger than a second threshold value or not can be judged, and if the average measurement value is larger than the second threshold value, the human body is considered to be detected; and if the measured value at the current moment is smaller than the second threshold value, determining that the object other than the human body is detected.
Step S230: and if the average measured value is less than or equal to the first threshold value corresponding to the reference value, calculating the weighted average value in the adjusting period.
The adjustment period may be set to 5 seconds, all the measurement values of the first signal within 5 seconds are acquired, and a weighted average of all the measurement values is calculated to obtain a weighted average.
Step S240: the reference value is adjusted to a weighted average.
The initial value of the reference value is updated to a weighted average value. Fixing the weighted average to the adjusted reference value if the controller is configured to adjust the reference value only once after power-on; if the controller is configured to adjust the reference value a plurality of times after power-on, the weighted average is taken as the reference value before the next adjustment of the reference value, and the reference value is updated after the next adjustment of the reference value.
Further, after the reference value is adjusted, the corresponding first threshold value and the second threshold value also need to be adjusted, where the first threshold value is adjusted to be 1.3 times of the new reference value, and the second threshold value is adjusted to be 1.6 times of the new reference value.
If no human body is detected within the first distance, it jumps to step S150.
Step S120: and if the human body is detected within the first distance, controlling a display screen of the intelligent household equipment to wake up and output an image.
If the first signal is larger than the second threshold value and the second signal is larger than the third threshold value, generating an awakening signal according to the fact that the current state of the intelligent household equipment is in a standby state, controlling the intelligent household equipment to enter the awakening state according to the awakening signal, sending a display signal to a display panel of the display screen, and not sending a screen lightening signal to a backlight module of the display screen, so that the display panel outputs an image corresponding to the display signal in the screen lightening state; and if the current state of the intelligent household equipment is the awakening state, keeping the awakening state and sending a display signal to a display panel of the display screen, and not sending a screen lightening signal to a backlight module of the display screen, so that the display panel outputs an image corresponding to the display signal in the screen resting state.
Step S130: whether a human body exists in a second distance of the intelligent household equipment is detected, and the second distance is smaller than the first distance.
The active infrared sensor is used as a second distance sensor, infrared rays are sent to the front of the intelligent household equipment through the second distance sensor, a second signal is generated according to the reflected infrared rays, and the second signal is sent to the controller.
According to the second signal, the close distance of the intelligent household equipment can be obtained, if an object exists in the second distance, when different objects are located in the second distance of the intelligent household equipment, the variation of the second signal is different, and the variation of the second signal when the human body appears in the second distance of the intelligent household equipment can be determined in advance through a second comparison experiment. The experimental procedure for a second control experiment was as follows:
when no human body exists within a second distance of the intelligent household equipment, acquiring a second signal measured by a second distance sensor as a comparison value; when a human body exists in a second distance of the intelligent household equipment, acquiring a second signal measured by a second distance sensor as an experimental value, wherein when the experimental value is calculated, a plurality of human bodies can stand in the second distance of the intelligent household equipment in sequence to obtain a plurality of second signals, and a weighted average value of the plurality of second signals is used as the experimental value; and obtaining a third threshold value corresponding to the comparison value according to the experimental value.
And if the second signal is larger than the third threshold value, indicating that the user reaches the second distance of the intelligent household equipment.
Step S140: and if the human body is detected within the second distance, controlling the display screen to light up the screen.
And if the current state of the intelligent household equipment is the awakening state, generating a screen lightening signal, and sending the screen lightening signal to the backlight module of the display screen, so that the display panel displays an image corresponding to the display signal in the screen lightening state.
The method comprises the steps that a human body is detected within a first distance, the fact that a user possibly moves towards the intelligent household equipment from within the first distance of the intelligent household equipment is indicated, the user only controls the display screen to output images but not brighten the screen to display image contents is detected according to the first distance, and the display panel is lightened to conduct bright screen display after the user reaches a second distance.
Compared with the method that the user controls the display screen to enter the awakening state and display the image after reaching the second distance, the method and the device can reduce the time for the user to wait for the display screen to enter the awakening state; compared with the method that the image is displayed in a bright screen mode before the user reaches the second distance, the method and the device can reduce energy consumption of the intelligent household equipment.
Step S150: and if no human body exists in the first distance of the intelligent household equipment, controlling the display screen to enter a standby state or keep the standby state.
If the first signal is smaller than the second threshold value, keeping the standby state according to the current state of the intelligent household equipment; and entering a standby state according to the fact that the current state of the intelligent household equipment is an awakening state so as to reduce energy consumption of the intelligent household equipment.
It should be noted that the second distance sensor may detect the human body according to the first distance sensor, and does not start detection when the first distance sensor does not detect the human body, so as to reduce energy consumption of the smart home device; of course, the second distance sensor can also be in a detection state all the time like the first distance sensor, so as to improve the detection sensitivity, and avoid the problem that the first distance sensor cannot normally detect a human body in the first distance and cannot normally start due to improper setting of the first threshold value and the second threshold value, or damage to the first distance sensor and other reasons.
When the second distance sensor is set to be in a detection state as the first distance sensor, the situation that the first distance sensor and the second distance sensor do not detect a human body may occur, and at this time, the second distance sensor can be in a standby state according to the current state of the intelligent home equipment, and then the second distance sensor is kept in the standby state; and entering a standby state according to the fact that the current state of the intelligent household equipment is an awakening state so as to reduce energy consumption of the intelligent household equipment.
When the second distance sensor is set to be in the detection state all the time as with the first distance sensor, there may also be a case where the first distance sensor does not detect a human body but the second distance sensor detects a human body. For example, the controller may determine that the human body is detected within the first distance if the analysis of the first signal by the controller is interfered by infrared rays in the environment of the smart home device, and may determine that the human body is detected within the second distance according to the second signal when the user reaches the front of the smart home device.
At this time, the display screen may be in a standby state, since the second distance sensor detects a human body, it is indicated that the user has reached within the second distance of the smart home device, and at this time, regardless of whether the first signal is greater than the second threshold, the display screen needs to be immediately turned on to display an image.
