For the purposes of making the objects, embodiments and advantages of the present application more apparent, an exemplary embodiment of the present application will be described more fully hereinafter with reference to the accompanying drawings in which exemplary embodiments of the application are shown, it being understood that the exemplary embodiments described are merely some, but not all, of the examples of the application.

It should be noted that the brief description of the terminology in the present application is for the purpose of facilitating understanding of the embodiments described below only and is not intended to limit the embodiments of the present application. Unless otherwise indicated, these terms should be construed in their ordinary and customary meaning.

Furthermore, the terms "comprise" and "have," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a product or apparatus that comprises a list of elements is not necessarily limited to those elements expressly listed, but may include other elements not expressly listed or inherent to such product or apparatus.

Aiming at the problem that one remote controller controls one electric appliance, the number of the remote controllers is large. At present, control over multiple household appliances can be realized based on AIOT technology and voice control, wherein AIOT technology depends on network and AI identification, and has higher requirements on stability of the network and accuracy of the AI identification, and the voice control has the problems of higher false triggering rate, inaccurate semantic analysis and the like.

Therefore, the application provides the remote controller, household appliances are classified, the types of the appliances are switched through the type switching key, the target appliance to be controlled is selected from a plurality of devices of the switched appliance types through the appliance selection key, the plurality of appliances can be controlled, and the efficiency of controlling the plurality of household appliances by a user is improved.

The technical scheme of the present application will be described in detail with reference to specific examples. The following specific embodiments may be combined with each other or may exist independently, and the same or similar concepts or processes may not be repeated in some embodiments, and embodiments of the present application will be described below with reference to the drawings.

Fig. 1 is a schematic structural diagram of a remote controller according to an embodiment of the present application, and as shown in fig. 1, a remote controller 10 includes a controller 101, a type switching key 102, an electric appliance selecting key 103, and a plurality of function keys 104.

The type switching key 102 is electrically connected to the controller 101. The type switching key 102 has a first state corresponding to a first appliance type including a plurality of first appliances and a second state corresponding to a second appliance type including a plurality of second appliances.

The first electrical appliance type may be an audio-visual electrical appliance type, and the plurality of first electrical appliances may include, for example, televisions, set-top boxes, speakers, intelligent projection devices, etc., and electrical appliances having a playing function such as audio and/or video may be classified into one type. The second appliance type may be a household appliance type, and the plurality of second appliances may include, for example, appliances of an air conditioner, a fan, a smart lamp, a curtain, etc., which may be classified into appliances having a plurality of modes of operation.

Based on the above classification, each variable function key is configured with two functions to realize corresponding control of electric appliances of different electric appliance types.

In one possible implementation, when the state of the type switching key 102 is switched, the function of each variable function key is changed accordingly, so that the function of the current variable function key corresponds to the corresponding appliance type.

An appliance selection button 103 electrically connected to the controller 101 and configured to select one of the first appliances or one of the second appliances. It is 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.

The plurality of function keys 104 are electrically connected to the controller 101, respectively, so that the controller 101 can control the controlled electric appliance based on the states (pressed) of the plurality of function keys 104.

Wherein, the type switching key 102 is switched to the first state, the electric appliance selection key 103 is adjusted to select a first electric appliance, and when one of the plurality of function keys is triggered, the controller 101 is caused to send a control signal corresponding to the function key to the first electric appliance.

Specifically, when the type switching key 102 is switched to the first state and the appliance selection key 103 is adjusted to select one first appliance, it is indicated that the user selects any one first appliance (for example, appliance a) of the first appliance type at this time, and if one of the plurality of function keys (for example, key 1) is detected to be triggered, it is indicated that the user initiates a corresponding function control through the function key (key 1) after selecting the appliance to be controlled, and the controller 101 may send a control signal corresponding to the function key (key 1) to the first appliance (appliance a).

When the type switching key 102 is switched to the second state, the electric appliance selection key 103 is adjusted to select a second electric appliance, and when any one of the plurality of function keys is triggered, the controller 101 is caused to send a control signal corresponding to the function key to the second electric appliance.

Specifically, when the type switching key 102 is switched to the second state and the appliance selection key 103 is adjusted to select one first appliance, it is indicated that the user selects any one first appliance (for example, appliance b) of the first appliance types at this time, and if one of the plurality of function keys (for example, key 1) is detected to be triggered, it is indicated that the user initiates a corresponding function control through the function key (key 1) after selecting the appliance to be controlled, and the controller 101 may send a control signal corresponding to the function key (key 1) to the first appliance (appliance b).

At this time, the key 1 is different in function when the type switching key 102 is in a different state.

It should be understood that the plurality of function keys 104 may be configured as a circuit corresponding to a matrix key, and as shown in fig. 2, fig. 2 is an exemplary circuit schematic corresponding to a matrix key of the present application, where the plurality of function keys 104 are arranged in 4 ROWs and 4 columns, and the connection manner between the keys in each ROW and the controller 101 is shown in fig. 2, and the controller 101 may be connected to the matrix key through a plurality of pins (k_line3, k_line2, k_line1, k_line0, k_ROW3, k_ROW2, k_ROW1 and k_ROW0).

The controller 101 may determine the activated function key by the level state of the corresponding pin for each row and each column.

For example, the controller 101 may output low levels from the pins corresponding to 4 rows, at this time, collect the level states of the pins corresponding to 4 columns, if the levels corresponding to 4 columns output high levels, it indicates that no key is triggered, and if the levels corresponding to one of the 4 columns output low levels, it indicates that there is a key in the column that is triggered. At this time, the controller 101 outputs the low level of the pins corresponding to the keys of each row in turn, and then detects the level of the pins corresponding to the keys of each column to determine the triggered key. Taking the first row of keys as an example, the controller 101 controls the circuit of the pin corresponding to the first row of keys to output a low level, and the pins corresponding to the other rows of keys to output a high level, at this time, the levels of the pins corresponding to the 4 columns of keys are collected, if both the levels are high levels, it is indicated that the row of keys are not triggered by the keys, otherwise, if one low level (for example, the second column) exists in the levels of the pins corresponding to the 4 columns of keys, it is indicated that the keys corresponding to the first row and the second column are triggered.

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

Next, the type switching key 102 and the appliance selecting key 103 will be described in detail.

Fig. 3 is a schematic structural diagram of a type switching key 102 according to an embodiment of the present application, and as shown in fig. 3, the type switching key 102 includes a first contact, a second contact, a fixed end, and a lever 21 connected to the fixed end.

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

When the first contact is turned on by the lever 21, the level signal output by the preset pin is at a high level, and the high level is used for indicating that the type switching key is switched to the first state.

When the second contact is turned on by the lever 21, the level signal output by the preset pin is at a low level, and the low level is used for indicating that the type switching key is switched to the second state.

Illustratively, the preset pin of the controller 101 may be a general purpose input/output port (General Purpose Input Output, GPIO).

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

In one possible implementation, the appliance selection button 103 includes a rotatable thumbwheel 31, a first end fixedly connected to one end of the thumbwheel 31, and a fixed contact.

Wherein the controller 101 is connected to the fixed contact and the first terminal through different pins, respectively. The plurality of first appliances and the plurality of second appliances have different appliance serial numbers.

When the thumb wheel 31 is adjusted to trigger the fixed contact once, the appliance selection key 103 is adjusted to select one appliance number, so that the controller 101 selects an appliance corresponding to the appliance number from the plurality of first appliances or the plurality of second appliances.

In one possible implementation, the fixed endpoint includes a first contact and a second contact.

Fig. 4 is a schematic circuit diagram of an electrical apparatus selection button 103 and a controller 101 according to an embodiment of the present application, as shown in fig. 4, a first pin (k_row0) of the controller 101 is connected to a first terminal, a second pin (k_line0) of the controller 101 is connected to a first contact, and a third pin (k_line2) of the controller 101 is connected to a second contact.

When the thumb wheel 31 is adjusted to trigger the second contact, the first pin and the third pin of the controller 101 form a loop. When the thumb wheel 31 is adjusted to trigger the first contact, the second pin and the first pin of the controller 101 form a loop.

It should be noted that, taking the second contact as an example, when the thumb wheel 31 is adjusted to the second contact, after the first pin and the third pin form a loop, the thumb wheel 31 automatically returns to the non-trigger state (i.e. is not connected with the first contact and the second contact), and when the thumb wheel 31 is shifted again to trigger the second contact, the first pin and the third pin form a loop again, so that the process is repeated.

When the thumb wheel 31 is adjusted to trigger the second contact 1 time, the controller 101 detects that the first pin and the third pin form a loop, and the serial number of the currently selected appliance may be +1. When the thumb wheel 31 is adjusted to trigger the first contact 1 time, 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 numbered-1. The updated serial number is the serial number of the electric appliance to be selected.

Illustratively, the first memory of the remote controller 10 stores therein the serial number of the first appliance currently selected and the serial number of the second appliance currently selected. Specifically, the serial number of the first appliance type may be stored in the first storage area, and the serial number of the second appliance type may be stored in the second storage area. The second memory of the remote controller 10 stores configuration information of a plurality of first appliances corresponding to the first appliance type and configuration information of a plurality of second appliances corresponding to the second appliance type. Specifically, the configuration information of the plurality of first electrical appliances may be stored in the third storage area, and the configuration information of the plurality of second electrical appliances may be stored in the fourth storage area.

When the controller 101 detects that the first pin and the third pin form a loop, the controller 101 is triggered to read data in a storage area corresponding to the current electrical appliance type. For example, if the current appliance type is the first appliance type, the controller 101 may read the serial number of the first appliance currently selected in the first storage area and obtain the serial number +1, for example, the serial number a is obtained, and then the controller 101 may read, in the third storage area in the second memory, configuration information of the first appliance corresponding to the serial number a, where the configuration information may be used by the controller 101 to perform corresponding control on the first appliance corresponding to the serial number. Exemplary, the configuration information includes function information of a function key corresponding to the first electrical appliance, display content on a display screen, and the like.

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

The first Memory may be a Static Random-Access Memory (SRAM), for example. The second Memory may be a Flash Memory (Flash).

Fig. 5 is a schematic structural diagram of a remote controller according to an embodiment of the present application, and as shown in fig. 5, a plurality of function keys 104 include a plurality of fixed function keys 41 and a plurality of variable function keys 42.

The variable function key 42 differs in function in which the type switching key 102 is in a different state for any one of the variable function keys 42.

Wherein a plurality of variable function keys 42 and a type switching key 102 are provided at the variable key section 43. Grooves 44 are provided around the variable key portion 43. A cover 45 slidably disposed along the groove 44 is provided above the variable key portion 43. The cover 45 is provided with a plurality of windows 46 corresponding to the variable function keys. The type switching key 102 is fixedly connected with the cover plate 45.

The opposite sides of each variable function key 42 are provided with a first indication portion 421 and a second indication portion 422. The first indication part 421 is used for displaying the function name corresponding to the first appliance type. The second indicator 422 is used for displaying the function name corresponding to the second appliance type.

For example, for any one of the variable function keys 42, the first indication portion 421 of the variable function key may have printed therein a function name corresponding to the variable function key in the first appliance type. The second indication part 422 of the variable function key may have printed therein a function name corresponding to the variable function key in the second appliance type.

When the type switching key 102 is switched to the first state, the type switching key 102 pushes the cover 45 to slide to the first position, so that the plurality of windows display the plurality of variable function keys 42 and the first indication portion 421 of each variable function key. When the type switching key 102 is switched to the second state, the type switching key 102 pushes the cover 45 to slide to the second position, so that the plurality of windows display the plurality of variable function keys 42 and the second indication portion 422 of each variable function key.

Exemplary, fig. 5 is a schematic view of the cover 45 sliding to the second position, and fig. 6 is a schematic view of the cover 45 sliding to the first position.

In a possible implementation manner, fig. 7 is a schematic position diagram of an electric appliance selection key 103 provided by the present application, as shown in fig. 7, the electric appliance selection key 103 may be disposed on a side wall of a remote control body, and by disposing a stimulable electric appliance selection key on the side wall of the remote control body, the electric appliance selection key is adapted to a gesture of a user holding the remote control, and can quickly select different electric appliances under the selected electric appliance type.

In one possible implementation, the remote control 101 further includes a plurality of first LEDs and a plurality of second LEDs, the plurality of first LEDs being respectively disposed inside the plurality of fixed function keys, and the plurality of second LEDs being respectively disposed inside the variable key section 43.

Wherein the plurality of second LEDs are configured to illuminate either the first indicator portion or the second indicator portion of the plurality of variable function keys.

In one possible implementation, the first plurality of LEDs and the second plurality of LEDs may be illuminated when the remote control 10 is activated.

In one possible implementation, the plurality of first LEDs and the plurality of second LEDs may illuminate when the appliance selection key is modulated to the target appliance, wherein the target appliance is one of the plurality of first appliances or the plurality of second appliances.

In one possible implementation, when the appliance selection key 103 is adjusted to select the target appliance, the controller 101 is configured to control a target LED of the plurality of second LEDs to light, the target LED being an LED corresponding to a variable function key that can be used to control the target appliance.

It will be appreciated that, for the plurality of variable function keys 42, it is not necessarily applicable to all the first electrical appliances or the second electrical appliances, and if the plurality of second LEDs are all turned on at this time, it is inconvenient for the user to distinguish between the variable function keys that can be used to control the target electrical appliance, and energy waste is also caused. The controller 101 may control the illumination of the LED under the variable function key that may be used to control the target appliance, and avoid illuminating the variable function key that cannot be used to control the target appliance by illuminating only the LED that may be used to control the variable function key corresponding to the target appliance, so as to instruct the user to control the target appliance through the illuminated variable function key, and may achieve energy saving. For example, fig. 8 is a schematic diagram illustrating the positions of a plurality of second LEDs according to an embodiment of the present application, fig. 8 is a schematic diagram illustrating the inside of the cover 45, and as shown in fig. 8, a plurality of variable function keys may be disposed in a plurality of columns in the variable key portion 43, one second LED is disposed on one side of each variable function key, and for three variable function keys located below the variable key portion 43, one second LED is disposed on the other side of each variable function key.

That is, for the three variable function keys, one second LED is provided on each of opposite sides thereof for illuminating the first indication portion and the second indication portion, respectively.

Taking fig. 8 as an example, the controller 101 may control the second LEDs 1, 2, 3, 4, 5, 6, 7, and 8 to be lighted when the cover 45 is slid to the first position. For any one of the second LEDs, the first indication portion of the variable function key may be illuminated through a window corresponding to the variable function key corresponding to the second LED.

Similarly, when the cover 45 is slid to the second position, the controller 101 may control the second LEDs 3, 4, 5, 6, 7, 8, 9, 10, and 11 to be lit. For any one of the second LEDs, the second indicator of the variable function key may be illuminated through a window corresponding to the variable function key corresponding to the second LED.

In a possible implementation manner, fig. 9 is 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, where, as shown in fig. 9, the first LEDs and the second LEDs are not identified in fig. 9, and are each represented by an LED. The controller 101 may control the on/off of the LEDs through the control circuit including a driving circuit and a backlight matrix formed of a plurality of first LEDs and a plurality of second LEDs. It will be appreciated that the number of LEDs in fig. 9 is merely an example, and the present application is not limited to the number of the plurality of function keys 104 of the remote controller.

In one possible implementation, for LEDs that do not need to be lit, the controller 101 may control its current to 0.

Illustratively, based on fig. 9 described above, the current of each LED may be controlled by equation (1):

Wherein V _BAT is the power supply voltage of the driving circuit, V _F is the turn-on voltage of the LED, V _r is the voltage drop of the driving circuit for scanning the backlight matrix in rows, and V _c is the voltage drop of the driving circuit for scanning the backlight matrix in columns. R _r is a current limiting resistor in series with the LED.

In one possible implementation, the remote control 10 further includes a display screen 105 electrically connected to the controller 101. The display screen 105 may refer to fig. 5 or fig. 6.

When the appliance selection button 103 is adjusted to select a target appliance, the controller 101 controls the display screen to display an identifier of the target appliance, where the identifier is used to prompt the user that the currently selected appliance is the target appliance, and the target appliance is one of the plurality of first appliances or the plurality of second appliances.

By way of example, the identification may be the name of the appliance, an icon representing the appliance, etc., as the application is not limited in this regard.

The corresponding interface is displayed through the display screen 105, so that a user can intuitively determine the selected electric appliance, the control efficiency of the electric appliance is improved, and the use experience of the user is improved.

Fig. 10 is a schematic structural diagram of a remote controller according to an embodiment of the present application, and as shown in fig. 10, the remote controller 10 further includes a trigger detection sensor 106, where the trigger detection sensor 106 is electrically connected to the controller 101.

When the trigger detection sensor 106 detects that the remote controller 10 is touched, a wake-up signal for instructing to wake up the remote controller 10 is transmitted to the controller 101.

For example, the trigger detection sensor 106 may be a gravity sensor (G-sensor), an acceleration sensor, or other contact sensor, and determines whether the remote controller 10 is picked up by performing detection such as movement of the remote controller 10 or touching by a human body, so that a wake-up signal may be transmitted to the controller 101 when the remote controller 10 is touched. By triggering the detection sensor 106 to detect whether the remote controller 10 is moved or picked up by the user, the remote controller 10 can be quickly awakened in response to the user's action, improving the user experience.

Fig. 11 is a schematic structural diagram of a remote controller according to an embodiment of the present application, and as shown in fig. 11, 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 illumination intensity of the environment in which the remote controller 10 is located. The illumination intensity is used to set the backlight brightness of the display screen 105, as well as the brightness of the first and second plurality of LEDs.

The controller 101 turns on the light sensor 107 after receiving the wake-up signal. The controller 101 may control the illumination 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 illumination intensity transmitted from the light sensor 107.

Illustratively, the controller 101 may control the backlight illumination of the LEDs according to equation (2):

Wherein, L is the backlight illumination of the LED, L _AM is the illumination intensity of the environment where the remote controller 10 is located, R _L is the reflectivity of the outer surface of the key corresponding to the LED, the reflectivity is a constant value, A _L is the transmittance of the LED divergent projection surface, ACR is the contrast ratio of the brightness of the LED illumination intensity passing through the key and the ambient illumination intensity, and generally any value between 0.1 and 0.2 is set, including 0.1 and 0.2.

Wherein, the brightness of the LED can be determined based on the divergence angle of the light emitted from the LED, the backlight illumination L of the LED:

wherein S _R is the divergence angle of the LED light emission, M _LED is the brightness of the LED, the unit is lux, and the unit of backlight illumination L is candela per square meter (cd/M2).

After determining M _LED, the controller 101 may determine the current corresponding to the luminance based on the curve as shown in fig. 12.

In one possible implementation, the remote control 10 is typically battery powered, with the battery voltage decreasing with increasing use time, presenting a problem of reduced LED brightness. This problem can be solved by two ways:

Mode 1 adds a voltage stabilizing circuit to the output voltage of the battery so that the battery provides a fixed supply voltage to the remote control 10.

In mode 2, the duty cycle of the LED current is adjusted so that the battery provides a fixed supply voltage to the remote control 10.

The remote controller 10 triggers the detection sensor 106 to maintain the monitoring mode in the standby or sleep state, and each key is in the scanning detection state. When the remote controller 10 is in the sleep or standby state, the trigger detection sensor 106 sends a wake-up signal output or a key is triggered, as shown in fig. 13, for example, the following timing of the operation of each component in the remote controller 10 is as follows:

During the T0 period, the controller 101 wakes up.

And in the time period T1, finishing the judgment of whether to wake effectively. For example, if a key is activated, it may be determined that the remote control 10 is awake. Or the trigger detection sensor 106 needs to continuously send n wake-up signals, it may be determined that the remote controller 10 is woken up, where n may be an integer greater than or equal to 1.

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

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

During the period of T4, 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 illumination intensity, and lights the display screen and the corresponding LED, for example, the LED may be an LED of a variable function key corresponding to the electric appliance controlled before dormancy.

If the trigger detection sensor 106 continuously transmits a wake-up signal or a key is triggered during the period T5, the LEDs that are turned on during the periods T4 and the display screen 105 remain on. If the electrical appliance switching key is triggered, the display screen 105 can be refreshed and the LEDs can be lightened for refreshing according to the switched electrical appliance. If the trigger detection sensor 106 is not triggered or no key is triggered, the display screen 105 and the LEDs are turned off.

In one possible implementation, the remote controller 10 may be a bluetooth chip, and the home appliances may be controlled through bluetooth and infrared rays in order to perform communication control with a plurality of home appliances.

In one 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.
