[0037] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be regarded as part of the specification.

[0038] In all the examples shown and discussed herein, any specific value should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0039] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings, and thus, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0040] Figure 1 It is a schematic diagram showing the circuit connection of a remote controller according to some embodiments of the present disclosure.

[0041] As Figure 1 shown, the remote controller 100 includes: a switching circuit 110, a control chip 120, a battery management chip 130, an energy storage module 140, and a load module 150. For convenience of description, Figure 1 a host computer 300 and a carrier communication line 170 are also shown. The carrier communication line 170 includes a power supply line 171 and an information transmission line 172. For example, the remote controller 100 can be a voice remote controller.

[0042] As Figure 1 shown, the control chip 120 is electrically connected to the switching circuit 110, the battery management chip 130, and the load module 150 respectively. The battery management chip 130 is electrically connected to the energy storage module 140 and the load module 150 respectively. The battery management chip 130 is electrically connected to the host computer 300 through the power supply line 171 of the carrier communication line 170. The switching circuit 110 is disposed on the power supply line 171. For example, the power supply line 171 includes a first wire 1711 and a second wire 1712. Both the first wire 1711 and the second wire 1712 are electrically connected between the host computer 300 and the battery management chip 130. Here, the first wire 1711, the second wire 1712, the host computer 300, and the battery management chip 130 can form a loop.

[0043] The switching circuit 110 is disposed on the first wire 1711 or the second wire 1712. It should be noted that although Figure 1 the switching circuit 110 is shown disposed on the first wire 1711 in the figure, the scope of the present disclosure is not limited thereto, and the switching circuit 110 can also be disposed on the second wire 1712.

[0044] The control chip 120 is configured to issue a first control signal S CRL1 and a second control signal S CRL2 . For example, the control chip 120 can be an MCU (Microcontroller Unit). The control chip 120 can obtain the state of the load module 150, and send the first control signal S CRL1 to the switching circuit 110 and the second control signal S CRL2 to the battery management chip 130 according to the state of the load module 150.

[0045] The switching circuit 110 is configured to according to the first control signal S CRL1Perform a conduction operation or a cutoff operation. In this way, by performing the conduction operation, the switching circuit 110 can enable the host computer to supply power to the load module through the carrier communication line, and by performing the cutoff operation, the host computer can be cut off from supplying power to the load module.

[0046] The battery management chip 130 is configured to perform a charging operation on the energy storage module 140 or a discharging operation on the energy storage module 140 according to the second control signal S. CRL2 Here, the battery management chip can be a battery management chip known to those skilled in the art. The charging and discharging of the energy storage module can be achieved here.

[0047] For example, when the load demand of the remote controller is greater than the carrier communication power supply capacity (i.e., the power supply capacity of the host computer to supply power to the load module through the carrier communication line), the energy storage module discharges; when the load demand of the remote controller is less than the carrier communication power supply capacity, the host computer charges the energy storage module through the carrier communication line. For example, when the remote controller is in standby, the power consumption of the voice speaker ≥ 1W. Usually, when the voice of the remote controller is turned on, it exceeds the carrier communication power consumption and needs to be powered by the energy storage module. Here, the power supply to the load can be achieved through the discharge of the energy storage module, so as to supply power to the load module when the power supply capacity of the carrier communication line is insufficient, and to solve the power supply problem of the remote controller as much as possible.

[0048] In some embodiments, when the load demand of the remote controller fluctuates at the critical point of the carrier communication power supply capacity, the energy storage module can be in a charging and discharging cycle state.

[0049] In some embodiments, the energy storage module 140 includes a lithium battery. For example, the power supply capacity of the lithium battery is greater than the power supply capacity of the carrier communication line. Of course, those skilled in the art can understand that other energy storage devices, such as supercapacitors, can also be used for the energy storage module. Therefore, the scope of the present disclosure is not limited thereto.

[0050] So far, a remote controller according to some embodiments of the present disclosure has been provided. The remote controller includes: a switching circuit, a control chip, a battery management chip, an energy storage module, and a load module. The control chip is electrically connected to the switching circuit, the battery management chip, and the load module respectively. The battery management chip is electrically connected to the energy storage module and the load module respectively. The battery management chip is electrically connected to the host computer through the power supply line of the carrier communication line. The switching circuit is arranged on the power supply line. The control chip is configured to issue a first control signal and a second control signal according to the state of the load module; the switching circuit is configured to perform a conduction operation or a cut-off operation according to the first control signal; and the battery management chip is configured to perform a charging operation on the energy storage module or perform a discharging operation on the energy storage module according to the second control signal. By arranging a switching circuit and an energy storage module in the remote controller and realizing the charging and discharging operations of the energy storage module according to the state of the load module, the power supply problem of the remote controller can be solved as much as possible, and the power consumption requirements of the remote controller can be met.

[0051] In some embodiments, as Figure 1 shown, the host computer 300 can be electrically connected to the load module 150 through the information transmission line 172 of the carrier communication line 170. In this way, communication between the host computer 300 and the load module 150 can be realized.

[0052] As mentioned above, when the load demand of the remote controller fluctuates at the critical point of the power supply capacity of the carrier communication, the energy storage module may be in a charging and discharging cycle state. For example, if the power supply line of the carrier communication line is continuously connected to the system, when the remote controller issues a voice or after a voice is finished, the energy storage module may be in a charging and discharging cycle state. In order to avoid frequent charging and discharging of the energy storage module, a remote controller according to some other embodiments of the present disclosure is provided. The following will be combined with Figure 2 to describe in detail the remote controller according to some other embodiments of the present disclosure.

[0053] Figure 2 is a schematic circuit connection diagram showing a remote controller according to some other embodiments of the present disclosure.

[0054] Similar to Figure 1 the remote controller 100 shown, Figure 2 the remote controller 200 shown includes a switching circuit 110, a control chip 120, a battery management chip 130, an energy storage module 140, and a load module 150. For example, the remote controller 200 is a voice remote controller.

[0055] As Figure 2 shown, the load module 150 includes a backlight sub-module 151 and a voice sub-module 152. For example, the load module may include a liquid crystal display, and the backlight sub-module 151 can provide backlight for the liquid crystal display. The voice sub-module 152 can receive voice information. In some other embodiments, the load module 150 may further include a speaker, etc.

[0056] The backlight sub-module 151 is electrically connected to the control chip 120. The backlight sub-module 151 is configured to emit light under the control of the control chip 120.

[0057] The voice sub-module 152 is electrically connected to the control chip 120. The voice sub-module 152 is configured to detect whether a voice wake-up word is received and send the detection result to the control chip 120. Here, the voice wake-up word is used to wake up the voice function of the remote controller, which can prevent misoperation. If the voice sub-module 152 receives the voice wake-up word, it will inform the control chip of the detection result of receiving the voice wake-up word; otherwise, it will inform the control chip of the detection result of not receiving the voice wake-up word.

[0058] The control chip 120 can be configured to determine the current state of the remote controller based on whether the backlight sub-module emits light and whether the voice sub-module detects a voice wake-up word, and issue a first control signal and a second control signal according to the current state of the remote controller. Here, the states of the aforementioned load module include: the state of whether the backlight sub-module emits light and the state of whether the voice sub-module detects a voice wake-up word.

[0059] For example, when designing the remote controller, the power consumption of various states of the load module can be obtained (for example, through actual measurement or theoretical calculation). Therefore, the control chip can determine the state of the load module based on whether the backlight sub-module emits light and whether the voice sub-module detects a voice wake-up word, and thus determine the current state of the remote controller. Also, since the power supply capacity of the upper computer to the load module through the carrier communication line is fixed, the control chip can know the relationship between the load demand of the remote controller and the power supply capacity of the carrier communication based on whether the backlight sub-module emits light and whether the voice sub-module detects a voice wake-up word. Therefore, the control chip can issue a first control signal and a second control signal according to the current state of the remote controller, so as to realize the control of the switching circuit and the battery management chip.

[0060] In some embodiments, the control chip 120 can be configured to determine that the remote controller is in the standby state when the backlight sub-module does not emit light and the voice sub-module does not detect a voice wake-up word; and determine that the remote controller is in the state where the product is being operated when the backlight sub-module emits light.

[0061] For example, the states in which the product is being operated include: the state in which the product is being operated and the voice is turned on, and the state in which the product is being operated and the voice is not turned on. The control chip 120 can be configured to determine that the line controller is in the state where the product is being operated and the voice is turned on when the backlight sub-module emits light and the voice sub-module detects a voice wake-up word; and to determine that the line controller is in the state where the product is being operated and the voice is not turned on when the backlight sub-module emits light and the voice sub-module does not detect a voice wake-up word.

[0062] In some embodiments, the control chip 120 can be configured to issue a first control signal that causes the switching circuit to conduct and a second control signal that causes the battery management chip to perform a charging operation on the energy storage module when the line controller is in the standby state; and to issue a first control signal that causes the switching circuit to turn off and a second control signal that causes the battery management chip to perform a discharging operation on the energy storage module when the line controller is in the state where the product is being operated. That is, the control chip can control the power supply to the load module through the host computer and charge the energy storage module when the line controller is in the standby state; and control the power supply to the load module through the energy storage module when the line controller is in the state where the product is being operated, and at this time, the host computer does not supply power to the load module.

[0063] That is, when the line controller is in the standby state, the power consumption requirement is low, and at this time, it may not be necessary to supply power from the energy storage module (for example, a lithium battery), and the power supply through the carrier communication line can meet the product requirements; when the line controller is in the state where the product is being operated but the voice is not turned on, the power consumption requirement is large at this time, and the energy storage module is required to supply power; when the line controller is in the state where the product is being operated and the voice is turned on, the power consumption requirement is the largest at this time, and the energy storage module is required to supply power.

[0064] For example, Table 1 shows the power supply methods in different states. In Table 1, "backlight on" means that the backlight sub-module emits light, and "backlight off" means that the backlight sub-module does not emit light.

[0065] Table 1 Power supply methods in different states

[0066] Backlight Voice Carrier power supply Power supply mode Off Not enabled Connected to the system Carrier power supply On Enabled Not connected to the system Energy storage module power supply On Not enabled Not connected to the system Energy storage module power supply

[0067] For example, there is a wake-up word before the voice line controller turns on the voice. When the wake-up word is detected, the carrier communication power supply line is cut off, and power is supplied through the energy storage module (for example, a lithium battery); when it is detected that the backlight of the voice line controller is off and the voice wake-up word is not detected, it is determined that the voice line controller is in the standby state. At this time, the carrier communication power supply line is connected, that is, carrier power supply is performed on the load module of the voice line controller.

[0068] In the above embodiment, the control chip determines the current state of the wire controller according to whether the backlight submodule emits light and whether the voice submodule detects the voice wake-up word, and sends a first control signal and a second control signal according to the current state of the wire controller. For example, when the wire controller is in a standby state, the switching circuit is turned on to realize carrier power supply (that is, the host computer supplies power to the load module through the carrier communication line), and the energy storage module is charged; when the wire controller is in a state where the product is being operated (for example, the product is being operated and the voice is turned on, or the product is being operated and the voice is not turned on), the switching circuit is turned off, and the energy storage module is discharged, that is, the power supply of the energy storage module is realized. In other words, in different states of the wire controller, the power is supplied by either the host computer through the carrier communication line or the energy storage module. In this way, frequent charging and discharging of the energy storage module can be avoided as much as possible, and the service life of the energy storage module can be increased.

[0069] The above-mentioned wire controller can automatically switch whether the carrier communication power supply is connected to the system according to the load status (or power consumption) under the premise of ensuring reliable communication.

[0070] In some embodiments, Figure 2 As shown, the wire controller 200 may further include a backlight control circuit 180. The backlight control circuit 180 is electrically connected to the control chip 120 and the backlight sub-module 151 respectively. The backlight control circuit 180 is configured to receive a third control signal S from the control chip 120. CRL3 , and based on the third control signal S CRL3 Here, the control chip 120 is configured to send a third control signal S CRL3 Then it is determined that the backlight sub-module 151 emits light.

[0071] That is, the control chip 120 sends the third control signal S to the backlight control circuit 180. CRL3 , the backlight control circuit 180 receives the third control signal S CRL3 Then the backlight sub-module 151 is controlled to emit light. Therefore, the control chip 120 sends the third control signal S CRL3 In this case, it can be determined that the backlight sub-module 151 is emitting light.

[0072] Figure 3 is a circuit connection diagram showing a switching circuit according to some embodiments of the present disclosure. Figure 3 As shown, the switching circuit 110 includes a first switching transistor T1 and a first resistor R1.

[0073] The first electrode 311 of the first switching transistor T1 is electrically connected to the host computer 300. The second electrode 312 of the first switching transistor T1 is electrically connected to the battery management chip 130. The control electrode (such as the gate) 313 of the first switching transistor T1 is electrically connected to the control chip 120. The control electrode (such as the gate) 313 of the first switching transistor T1 is configured to receive the first control signal S CRL1 . For example, as Figure 3 shown, the first switching transistor includes a MOS transistor (Metal - Oxide - Semiconductor Field - Effect Transistor). Another example is that the first switching transistor includes a bipolar transistor.

[0074] In some embodiments, as Figure 3 shown, the first switching transistor T1 can be disposed on the first wire 1711. In other embodiments, the first switching transistor T1 can be disposed on the second wire 1712.

[0075] The first end 321 of the first resistor R1 is electrically connected to the first electrode 311 of the first switching transistor T1. The second end 322 of the first resistor R1 is electrically connected to the control electrode of the first switching transistor T1. In some embodiments, the resistance value range of the first resistor R1 can be from several kilo - ohms to several tens of kilo - ohms. For example, the resistance value of the first resistor R1 can be 5 kΩ, 10 kΩ, or 50 kΩ, etc.

[0076] So far, the switching circuit of the line controller according to some embodiments of the present disclosure has been described.

[0077] The following takes the first switching transistor as an NMOS (N - Metal - Oxide - Semiconductor) transistor as an example to describe the working process of the switching circuit: When the first control signal S CRL1 is a low - level signal, the first switching transistor is turned off, and at this time, the carrier power supply is disconnected, that is, the host computer cannot supply power to the load module; when the first control signal S CRL1 is a high - level signal, the first switching transistor is turned on, and the carrier power supply is connected, that is, the host computer supplies power to the load module through the power supply line of the carrier communication line. In this way, the on - off of the switching circuit is realized.

[0078] Figure 4 is a circuit connection schematic diagram showing a backlight control circuit according to some embodiments of the present disclosure. As Figure 4 shown, the backlight control circuit includes a second switching transistor T2, a second resistor R2, a capacitor C, and a third resistor R3.

[0079] The first electrode 411 of the second switching transistor T2 is electrically connected to the negative terminal 1511 of the backlight photon module 151. The second electrode 412 of the second switching transistor T2 is electrically connected to the ground terminal 420. The control electrode (e.g., base) 413 of the second switching transistor T2 is electrically connected to the control chip 120. The control electrode of the second switching transistor T2 is configured to receive a third control signal S CRL3 . For example, the second switching transistor T2 may include a triode. Also for example, the second switching transistor T2 may include a MOS transistor. The second switching transistor T2 is configured to conduct after receiving the third control signal S CRL3 .

[0080] A second resistor R2 is disposed between the control electrode 413 of the second switching transistor T2 and the control chip 120.
