[0069] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0070] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their ordinary and common meanings.

[0071] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0072] The problem of a large number of remote controls, which results in one remote control controlling one appliance. Currently, multiple home appliances can be controlled based on AIOT technology and voice control. AIOT technology relies on the network and AI recognition, and has high requirements for network stability and AI recognition accuracy, while voice control has problems such as a high false trigger rate and inaccurate semantic analysis.

[0073] Therefore, the present application provides a remote control that classifies household appliances, switches appliance types through type switching buttons, and selects the target appliance to be controlled from multiple devices of the switched appliance type through appliance selection buttons, thereby realizing control of multiple appliances and improving the efficiency of users controlling multiple household appliances.

[0074] The technical solution of the present application is described in detail below in conjunction with specific embodiments. The following specific embodiments can be combined with each other or exist independently. The same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0075] Figure 1 A schematic diagram of the structure of a remote controller provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the remote controller 10 includes a controller 101 , a type switching button 102 , an appliance selection button 103 and a plurality of function buttons 104 .

[0076] The type switching button 102 is electrically connected to the controller 101. The type switching button 102 has a first state and a second state, the first state corresponds to a first electrical appliance type including a plurality of first electrical appliances, and the second state corresponds to a second electrical appliance type including a plurality of second electrical appliances.

[0077] For example, the first appliance type may be an audio-visual appliance type, and multiple first appliances may include, for example, televisions, set-top boxes, stereos, smart projection devices, etc. Such appliances with audio and / or video playback functions may be classified into one category. The second appliance type may be a household appliance type, and multiple second appliances may include, for example, air conditioners, fans, smart lights, curtains, etc. Such appliances with multiple modes of operation may be classified into one category.

[0078] Based on the above classification, each variable function button is configured with two functions to achieve corresponding control of electrical appliances of different electrical appliance types.

[0079] In a possible implementation, when the state of the type switching button 102 is switched, the functions of the variable function buttons are changed accordingly, so that the function of the current variable function button corresponds to the corresponding appliance type.

[0080] The appliance selection button 103 is electrically connected to the controller 101 and is configured to select a first appliance or a second appliance. It can be understood that the first appliance is any one of a plurality of first appliances, and the second appliance is any one of a plurality of second appliances.

[0081] The multiple function buttons 104 are electrically connected to the controller 101 respectively, so that the controller 101 can control the controlled electrical appliances based on the states (being pressed) of the multiple function buttons 104 .

[0082] Among them, the type switching button 102 is switched to the first state, the appliance selection button 103 is adjusted to select a first appliance, and when one of the multiple function buttons is triggered, the controller 101 sends a control signal corresponding to the function button to the first appliance.

[0083] Specifically, when the type switching button 102 is switched to the first state and the appliance selection button 103 is adjusted to select a first appliance, it means that the user has selected any first appliance of the first appliance type (for example, appliance a). If it is detected that one of the multiple function buttons (for example, button 1) is triggered, it means that the user has initiated corresponding function control through the function button (button 1) after selecting the appliance to be controlled. The controller 101 can send a control signal corresponding to the function button (button 1) to the first appliance (electrical appliance a).

[0084] When the type switching button 102 is switched to the second state, the appliance selection button 103 is adjusted to select a second appliance, and when any one of the multiple function buttons is triggered, the controller 101 sends a control signal corresponding to the function button to the second appliance.

[0085] Specifically, when the type switching button 102 is switched to the second state and the appliance selection button 103 is adjusted to select a first appliance, it means that the user has selected any first appliance of the first appliance type (for example, appliance b). If it is detected that one of the multiple function buttons (for example, button 1) is triggered, it means that the user has initiated corresponding function control through the function button (button 1) after selecting the appliance to be controlled. The controller 101 can send a control signal corresponding to the function button (button 1) to the first appliance (appliance b).

[0086] At this time, the function of button 1 is different when the type switching button 102 is in different states.

[0087] It can be understood that the plurality of function keys 104 can be configured as circuits corresponding to matrix keys. For example, Figure 2 This is a circuit diagram corresponding to a matrix key of the present application example, such as Figure 2 As shown, the plurality of function keys 104 are arranged in 4 rows and 4 columns. The connection between the keys in each row and column and the controller 101 can be referred to in Figure 2 , the controller 101 is connected to the matrix keys through multiple pins (K_LINE3, K_LINE2, K_LINE1, K_LINE0, K_ROW3, ​​K_ROW2, K_ROW1 and K_ROW0).

[0088] The controller 101 can determine the triggered function key by checking the level states of the pins corresponding to each row and each column.

[0089] Exemplarily, the controller 101 can output low levels to the pins corresponding to the 4 rows, and then collect the level states of the pins corresponding to the 4 columns. If the levels corresponding to the 4 columns all output high levels, it means that no key is triggered. If the level corresponding to one of the 4 columns outputs a low level, it means that a key in the column is triggered. At this time, the controller 101 outputs low levels to the levels of the pins corresponding to the keys of each row in turn, and then detects the levels of the pins corresponding to the keys of each column to determine the triggered keys. Taking the first row of keys as an example, the controller 101 controls the circuit of the pins corresponding to the first row of keys to output low levels, and the pins corresponding to the keys of other rows output high levels. At this time, the levels of the pins corresponding to the keys of the 4 columns are collected. If they are all high levels, it means that no key in the row is triggered. On the contrary, if there is a low level (for example, the second column) in the levels of the pins corresponding to the keys of the 4 columns, it means that the keys corresponding to the first row and the second column are triggered.

[0090] After determining that the target function button is triggered, the controller 101 may perform corresponding control according to the configuration information corresponding to the target function button.

[0091] Next, the type switching button 102 and the appliance selection button 103 are described in detail.

[0092] Figure 3 A schematic diagram of a type of switch button 102 provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the type switching button 102 includes a first contact point, a second contact point, a fixed end, and a lever 21 connected to the fixed end.

[0093] The preset pin of the controller 101 is electrically connected to the fixed end.

[0094] When the lever 21 is connected to the first contact, the level signal output by the preset pin is a high level, and the high level is used to indicate that the type switching button is switched to the first state.

[0095] When the lever 21 connects to the second contact, the level signal output by the preset pin is a low level, and the low level is used to indicate that the type switching button is switched to the second state.

[0096] Exemplarily, the preset pin of the controller 101 may be a general purpose input / output port (GPIO).

[0097] Taking the level state of the preset pin as a high level as an example, the controller 101 can read the identifier of the first electrical appliance type from the first memory, and read the configuration information corresponding to the identifier from the second memory, wherein the configuration information may include, for example, backlight control information of the function keys corresponding to the first electrical appliance type and display interface information of the display screen for the first electrical appliance type.

[0098] In this embodiment, the user can quickly select different types of electrical appliances by controlling different contact points connected to the lever.

[0099] In a possible implementation, the appliance selection button 103 includes a rotatable dial wheel 31 , a first end point fixedly connected to one end of the dial wheel 31 , and a fixed contact.

[0100] The controller 101 is connected to the fixed contact and the first end point through different pins. The plurality of first electrical appliances and the plurality of second electrical appliances have different electrical appliance serial numbers.

[0101] When the dial 31 is adjusted to trigger a fixed contact, the appliance selection button 103 is adjusted to select an appliance serial number, so that the controller 101 selects an appliance corresponding to the appliance serial number from the plurality of first appliances or the plurality of second appliances.

[0102] In a possible implementation manner, the fixed end point includes a first contact point and a second contact point.

[0103] Figure 4 FIG. 1 is a schematic diagram of a circuit structure of an electrical appliance selection button 103 and a controller 101 according to an embodiment of the present application. Figure 4 As shown, the first pin (K_ROW0) of the controller 101 is connected to the first end point, the second pin (K_LINE0) of the controller 101 is connected to the first contact point, and the third pin (K_LINE2) of the controller 101 is connected to the second contact point.

[0104] When the dial wheel 31 is adjusted to trigger the second contact point, the first pin and the third pin of the controller 101 form a loop. When the dial wheel 31 is adjusted to trigger the first contact point, the second pin and the first pin of the controller 101 form a loop.

[0105] It should be noted that, taking the second contact as an example, when the dial wheel 31 is adjusted to the second contact and the first pin and the third pin form a loop, the dial wheel 31 automatically returns to the non-triggered state (i.e., not connected to the first contact and the second contact). When the dial wheel 31 is turned again and the second contact is triggered, the first pin and the third pin form a loop again, and so on.

[0106] When the dial 31 is adjusted to trigger the second contact once, the controller 101 detects that the first pin and the third pin form a loop, and the serial number of the currently selected appliance can be increased by 1. When the dial 31 is adjusted to trigger the first contact once, the controller 101 detects that the first pin and the second pin form a loop, and the serial number of the currently selected appliance can be decreased by 1. The updated serial number is the serial number of the appliance to be selected.

[0107] Exemplarily, the first memory of the remote controller 10 stores the serial number of the currently selected first electrical appliance and the serial number of the currently selected second electrical appliance. Specifically, the serial number of the first electrical appliance of the first electrical appliance type can be stored in the first storage area, and the serial number of the second electrical appliance of the second electrical appliance type can be stored in the second storage area. The second memory of the remote controller 10 stores the configuration information of multiple first electrical appliances corresponding to the first electrical appliance type, and the configuration information of multiple second electrical appliances corresponding to the second electrical appliance type. Specifically, the configuration information of multiple first electrical appliances can be stored in the third storage area, and the configuration information of multiple second electrical appliances can be stored in the fourth storage area.

[0108] When the controller 101 detects that the first pin and the third pin form a loop, the controller 101 is triggered to read the data in the storage area corresponding to the current electrical appliance type. For example, if the current electrical appliance type is the first electrical appliance type, the controller 101 can read the serial number of the first electrical appliance currently selected in the first storage area, and add 1 to the serial number, for example, to obtain the serial number a, then the controller 101 can read the configuration information of the first electrical appliance corresponding to the serial number a in the third storage area in the second memory, and the configuration information can be used by the controller 101 to perform corresponding control on the first electrical appliance corresponding to the serial number. Exemplarily, the configuration information includes the function information of the function button corresponding to the first electrical appliance and the display content on the display screen, etc.

[0109] When the controller 101 detects that the first pin and the second pin form a loop, the controller 101 is triggered to read the data in the storage area corresponding to the current appliance type. For example, if the current appliance type is the first appliance type, the controller 101 can read the serial number of the first appliance currently selected in the first storage area, and subtract 1 from the serial number, for example, to obtain the serial number b, and the controller 101 can read the configuration information of the first appliance corresponding to the serial number b in the third storage area in the second memory.

[0110] Exemplarily, the first memory may be a static random access memory (SRAM), and the second memory may be a flash memory (FLASH).

[0111] Figure 5 A schematic diagram of the structure of a remote controller provided in an embodiment of the present application is shown in FIG. Figure 5 As shown, the plurality of function keys 104 include a plurality of fixed function keys 41 and a plurality of variable function keys 42 .

[0112] For any variable function key 42 , the function of the variable function key 42 is different when the type switching key 102 is in different states.

[0113] Among them, a plurality of variable function keys 42 and a type switching key 102 are arranged on a variable key portion 43. A groove 44 is arranged around the variable key portion 43. A cover plate 45 is arranged above the variable key portion 43 and is slidably arranged along the groove 44. A plurality of windows 46 corresponding to the variable function keys are arranged on the cover plate 45. The type switching key 102 is fixedly connected to the cover plate 45.

[0114] Each variable function button 42 is provided with a first indicator 421 and a second indicator 422 on opposite sides. The first indicator 421 is used to display the function name corresponding to the first electrical appliance type. The second indicator 422 is used to display the function name corresponding to the second electrical appliance type.

[0115] For example, for any variable function key 42, the first indicator portion 421 of the variable function key may be printed with the function name corresponding to the variable function key in the first electrical appliance type, and the second indicator portion 422 of the variable function key may be printed with the function name corresponding to the variable function key in the second electrical appliance type.

[0116] When the type switching button 102 is switched to the first state, the type switching button 102 pushes the cover plate 45 to slide to the first position, so that the multiple windows display the multiple variable function buttons 42 and the first indicator 421 of each variable function button. When the type switching button 102 is switched to the second state, the type switching button 102 pushes the cover plate 45 to slide to the second position, so that the multiple windows display the multiple variable function buttons 42 and the second indicator 422 of each variable function button.

[0117] For example, Figure 5 is a schematic diagram showing that the cover plate 45 slides to the second position, Figure 6 It is a schematic diagram showing that the cover plate 45 slides to the first position.

[0118] In this embodiment, multiple variable function buttons can be set in the function buttons of the remote control. Under different types of electrical appliances, the functions of the multiple variable function buttons are different, so that multiple types of electrical appliances can be controlled by the same variable function button.

[0119] In one possible implementation, Figure 7 A schematic diagram of the position of an appliance selection button 103 provided as an example of this application, such as Figure 7 As shown, the appliance selection button 103 can be set on the side wall of the remote control body. By setting a movable appliance selection button on the side wall of the remote control body, it is adapted to the user's gesture of holding the remote control, and different appliances can be quickly selected under the selected appliance type.

[0120] In a possible implementation, the remote control 101 further includes a plurality of first LEDs and a plurality of second LEDs, the plurality of first LEDs are respectively disposed inside a plurality of fixed function keys, and the plurality of second LEDs are respectively disposed inside the variable key portion 43 .

[0121] The plurality of second LEDs are configured to illuminate the first indication portion or the second indication portion of the plurality of variable function keys.

[0122] For any first LED among the plurality of first LEDs, the first LED is configured to illuminate the corresponding fixed function key.

[0123] In a possible implementation, when the remote controller 10 is turned on, the plurality of first LEDs and the plurality of second LEDs may light up.

[0124] In a possible implementation, when the appliance selection button is modulated to a target appliance, the plurality of first LEDs and the plurality of second LEDs may light up, wherein the target appliance is one of the plurality of first appliances or the plurality of second appliances.

[0125] In a possible implementation, when the appliance selection button 103 is adjusted to select a target appliance, the controller 101 is configured to control a target LED among the plurality of second LEDs to light up, where the target LED is an LED corresponding to a variable function button that can be used to control the target appliance.

[0126] It can be understood that the multiple variable function buttons 42 are not necessarily applicable to all first appliances or second appliances. If all the multiple second LEDs are lit at this time, it will be inconvenient for users to distinguish the variable function buttons that can be used to control the target appliance, and it will also cause energy waste. The controller 101 can control the lighting of the LEDs under the variable function buttons that can be used to control the target appliance. By only lighting the LEDs of the variable function buttons corresponding to the target appliance, it avoids lighting the variable function buttons that cannot be used to control the target appliance, so as to indicate that the user can control the target appliance through the illuminated variable function buttons, and energy saving can be achieved. Exemplary, Figure 8 This is a schematic diagram of the positions of multiple second LEDs in the example of this application. Figure 8 is a schematic diagram of the interior of the cover plate 45, such as Figure 8 As shown, a plurality of variable function keys can be arranged in a plurality of columns in the variable key portion 43, and a second LED is arranged on one side of each variable function key to Figure 8 Taking the multiple variable function keys as an example, for the three variable function keys located below the variable key portion 43, a second LED is further provided on the other side of the three variable function keys.

[0127] That is to say, for the three variable function keys, a second LED is respectively arranged on two opposite sides thereof, for illuminating the first indication portion and the second indication portion respectively.

[0128] by Figure 8 For example, when the cover plate 45 slides to the first position, the controller 101 can control the second LED 1, the second LED 2, the second LED 3, the second LED 4, the second LED 5, the second LED 6, the second LED 7 and the second LED 8 to light up. For any one of the second LEDs, the first indication portion of the variable function key corresponding to the second LED can be illuminated through the window corresponding to the variable function key corresponding to the second LED.

[0129] Similarly, when the cover plate 45 slides to the second position, the controller 101 can control the second LED 3, the second LED 4, the second LED 5, the second LED 6, the second LED 7, the second LED 8, the second LED 9, the second LED 10 and the second LED 11 to light up. For any one of the second LEDs, the second indication portion of the variable function key corresponding to the second LED can be illuminated through the window corresponding to the variable function key corresponding to the second LED.

[0130] In one possible implementation, Fig. 9 A schematic diagram of a control circuit of a plurality of first LEDs and a plurality of second LEDs provided in an embodiment of the present application, such as Fig. 9 As shown, Fig. 9 The first LED and the second LED are not identified, and are both represented by LED. The controller 101 can control the on and off of the LED through the control circuit, and the control circuit includes a driving circuit and a backlight matrix formed by a plurality of first LEDs and a plurality of second LEDs. It can be understood that Fig. 9 The number of LEDs is only an example, and the present application does not limit the number of the multiple function buttons 104 of the remote control.

[0131] In a possible implementation, for LEDs that do not need to be lit, the controller 101 may control the current thereof to be 0.

[0132] For example, based on the above Fig. 9 , the current of each LED can be controlled by formula (1):

[0133]

[0134] Among them, V BAT is the supply voltage of the drive circuit, V F is the LED turn-on voltage, V r V is the voltage drop of the driving circuit for scanning the backlight matrix. c It is the voltage drop when the driving circuit scans the backlight matrix column. r It is a current limiting resistor connected in series with the LED.

[0135] In a possible implementation, the remote controller 10 further includes: a display screen 105 electrically connected to the controller 101. The display screen 105 can refer to Figure 5 or Figure 6 .

[0136] When the appliance selection button 103 is adjusted to select a target appliance, the controller 101 controls the display screen to display the logo of the target appliance, which is used to prompt the user that the currently selected appliance is the target appliance, and the target appliance is an appliance among the multiple first appliances or the multiple second appliances.

[0137] Exemplarily, the identifier may be the name of the electrical appliance, an icon used to represent the electrical appliance, etc., and this application does not impose any limitation on this.

[0138] The corresponding interface is displayed on the display screen 105 so that the user can intuitively determine the selected electrical appliance, thereby improving the control efficiency of the electrical appliance and the user's usage experience.

[0139] Fig.10 A schematic diagram of the structure of a remote controller provided in an embodiment of the present application is shown in FIG. Fig.10 As shown, the remote controller 10 further includes a trigger detection sensor 106 , and the trigger detection sensor 106 is electrically connected to the controller 101 .

[0140] When the trigger detection sensor 106 detects that the remote controller 10 is touched, it sends a wake-up signal to the controller 101 , where the wake-up signal is used to instruct to wake up the remote controller 10 .

[0141] Exemplarily, the trigger detection sensor 106 may be a gravity sensor (G-sensor), an acceleration sensor, or other contact sensors, which can detect the movement of the remote controller 10 or human touch to determine whether the remote controller 10 is picked up, so that when the remote controller 10 is touched, a wake-up signal can be sent to the controller 101. By detecting whether the remote controller 10 is moved or picked up by the user through the trigger detection sensor 106, the remote controller 10 can be quickly awakened in response to the user's action, thereby improving the user experience.

[0142] Fig.11 A schematic diagram of the structure of a remote controller provided in an embodiment of the present application is shown in FIG. Fig.11 As shown, the remote controller 10 further includes a light sensor 107. The light sensor 107 is electrically connected to the controller 101. The light sensor 107 is configured to detect the light intensity of the environment where the remote controller 10 is located. The light intensity is used to set the backlight brightness of the display screen 105, as well as the brightness of the plurality of first LEDs and the plurality of second LEDs.

[0143] After receiving the wake-up signal, the controller 101 turns on the light sensor 107. The controller 101 can control the light intensity of the display screen 105 and the backlight brightness of the plurality of first LEDs and the plurality of second LEDs based on the light intensity sent by the light sensor 107.

[0144] Exemplarily, the controller 101 may control the backlight illumination of the LED according to formula (2):

[0145]

[0146] Where, L is the backlight illumination of LED, L AM is the light intensity of the environment where the remote controller 10 is located, RL is the reflectivity of the outer surface of the key corresponding to the LED, which is a constant value. L is the transmittance of the LED divergent projection surface, and ACR is the contrast between the brightness of the LED light intensity passing through the button and the ambient light intensity, which is usually set to any value between 0.1 and 0.2, including 0.1 and 0.2.

[0147] The brightness of the LED can be determined based on the divergence angle of the LED light and the backlight illumination L of the LED:

[0148]

[0149] Among them, S R is the divergence angle of LED light, M LED is the brightness of the LED, its unit is lux, and the unit of backlight illumination L is candela per square meter (cd / ㎡).

[0150] Determine M LED Afterwards, the controller 101 can be based on Fig.12 The curve shown determines the current corresponding to the brightness.

[0151] In a possible implementation, the remote controller 10 is usually powered by a battery. The battery voltage decreases with the increase of usage time, resulting in a problem of reduced LED brightness. This problem can be solved by the following two methods:

[0152] Method 1: adding a voltage stabilizing circuit to the output voltage of the battery so that the battery provides a fixed supply voltage for the remote controller 10 .

[0153] Mode 2, adjusting the duty cycle of the LED current so that the battery provides a fixed supply voltage for the remote controller 10 .

[0154] When the remote controller 10 is in the standby or dormant state, the trigger detection sensor 106 maintains the monitoring mode, and each button is in the scanning detection state. When the remote controller 10 is in the dormant or standby state, the trigger detection sensor 106 sends a wake-up signal output or a button is triggered, for example, Fig.13 As shown, the timing of the operation of each component in the remote controller 10 is as follows:

[0155] During the time period T0, the controller 101 wakes up.

[0156] Within the duration T1, the determination of whether the wake-up is effective is completed. For example, if a certain button is triggered, it can be determined that the remote controller 10 is awakened. Alternatively, the trigger detection sensor 106 needs to send n wake-up signals continuously, and then it can be determined that the remote controller 10 is awakened, where n can be an integer greater than or equal to 1.

[0157] During the time period T2 , the controller 101 controls the power supply and initialization of the light sensor 107 and the display screen 105 .

[0158] During the time period T3, the controller 101 reads the light intensity of the environment where the remote controller 10 is located detected by the light sensor 107, the serial number of the current appliance type of the remote controller 10, and the serial number of the appliance controlled before sleep.

[0159] During the T4 duration, the controller 101 refreshes the display content of the display screen, sets the current parameters of the display screen and each LED according to the light intensity, and lights up the display screen and the corresponding LED. For example, the LED can be the LED of the variable function button corresponding to the appliance controlled before sleep.

[0160] During the T5 duration, if the trigger detection sensor 106 continues to send a wake-up signal or a certain button is triggered, the display screen 105 and the LED that was lit during the T4 duration remain lit. If the appliance switching button is triggered, the display screen 105 can be refreshed and the LED can be refreshed according to the switched appliance. If the trigger detection sensor 106 is not triggered or no button is triggered, the display screen 105 and the LED are turned off.

[0161] In a possible implementation, in order for the remote controller 10 to communicate and control multiple household appliances, the controller 101 may be a Bluetooth chip, and the household appliances may be controlled via Bluetooth and infrared.

[0162] In a possible implementation, the controller 101 may also be connected to a radio frequency chip to control the radio frequency device in a radio frequency manner through the radio frequency chip.
