[0018] In one embodiment, the power-on circuit further includes:

[0019] The battery loading buffer circuit includes an overcurrent protection circuit and a second switching unit.

The negative terminal of the second switching unit is connected to the positive terminal of the first switching unit. The overcurrent protection circuit is used to provide grounding protection when an overcurrent occurs during battery loading, and to control the second switching unit to conduct when no grounding protection is provided.

[0020] In one embodiment, the overcurrent protection circuit includes:

[0027] This application discloses a power consumption control circuit, circuit board, and remote control. The circuit includes a power-on circuit, comprising a first switching unit; a first button circuit, comprising a first button connected in parallel to the positive terminal and control terminal of the first switching unit, the first button circuit being used to output a power-on signal and control the first switching unit to conduct when the first button is pressed; a conduction control circuit, connected in parallel to the positive terminal and control terminal of the first switching unit, the conduction control circuit being used to control the first switching unit to conduct when a conduction control signal is received; and a control unit, connected to the negative terminal of the first switching unit, the first button circuit, and the conduction control circuit, the control unit being used to output the conduction control signal to the conduction control circuit according to the power-on signal when the first button is pressed; when the power-on signal is received for a first preset duration, the output of the conduction control signal is maintained when the first button is released; and if no operation signal is received within a second preset duration, the output of the conduction control signal to the conduction control circuit is stopped. Because the circuit only powers on when the first button is pressed and locks itself after a first preset time following the generation of the power-on signal, it only consumes power when manually activated, thus reducing startup power consumption caused by accidental touches on the remote control. Furthermore, since the control unit stops outputting the conduction control signal if it does not receive any operation signal within a second preset time, the circuit can be directly powered off. This allows the circuit to consume no power during standby, effectively reducing standby power consumption and further reducing the overall power consumption of the remote control.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0033] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0035] In related technologies, with the popularization and development of IoT consumer electronics and industrial control equipment, users have placed higher demands on the remote controls for operating these devices. Traditional infrared remote controls have limitations such as high directional requirements, limited functionality, and susceptibility to environmental interference, failing to meet the needs of modern equipment for multi-functional, long-range, and highly reliable operation. Therefore, second-generation ZigBee, Wi-Fi, and BLE wireless communication remote control technologies have been developed and applied. However, the development of these new technologies also brings some challenges, especially in portable handheld battery-powered devices, where insufficient battery life affects the user experience.

[0036] To reduce the power consumption of the remote control, this application provides a power consumption control circuit, a circuit board, a remote control, and a power-on control method. The circuit includes a power-on circuit, comprising a first switching unit; a first button circuit, comprising a first button connected in parallel to the positive terminal and control terminal of the first switching unit, the first button circuit being used to output a power-on signal and control the first switching unit to conduct when the first button is pressed; a conduction control circuit, connected in parallel to the positive terminal and control terminal of the first switching unit, the conduction control circuit being used to control the first switching unit to conduct when a conduction control signal is received; and a control unit, connected to the negative terminal of the first switching unit, the first button circuit, and the conduction control circuit, the control unit being used to output a conduction control signal to the conduction control circuit according to the power-on signal when the first button is pressed; when a power-on signal of a first preset duration is received, the output of the conduction control signal is maintained when the first button is released; and if no operation signal is received within a second preset duration, the output of the conduction control signal to the conduction control circuit is stopped. Because the circuit only powers on when the first button is pressed and locks itself after a first preset time following the generation of the power-on signal, it only consumes power when manually activated, thus reducing startup power consumption caused by accidental touches on the remote control. Furthermore, since the control unit stops outputting the conduction control signal if it does not receive any operation signal within a second preset time, the circuit can be directly powered off. This allows the circuit to consume no power during standby, effectively reducing standby power consumption and further reducing the overall power consumption of the remote control.

[0037] See Figure 1 , Figure 1 The circuit structure of the power consumption control circuit provided in the embodiment of this application is shown. In the embodiment of this application, the power consumption control circuit may include a power-on circuit 1, a first button circuit 2, a conduction control circuit 3, and a control unit 4.

[0038] The power-on circuit 1 may include a first switch unit 11; the first button circuit 2 may include a first button 21, which may be connected in parallel to the positive terminal and the control terminal of the first switch unit 11. The first button circuit 2 may be used to output a power-on signal and control the first switch unit 11 to conduct when the first button 21 is pressed. The conduction control circuit 3 is connected in parallel to the positive terminal and the control terminal of the first switch unit 11. The conduction control circuit 3 may be used to control the first switch unit 11 to conduct when a conduction control signal is received. The control unit 4 is connected to the negative terminal of the first switch unit 11, the first button circuit 2, and the conduction control circuit 3 respectively. The control unit 4 may be used to output a conduction control signal to the conduction control circuit 3 according to the power-on signal when the first button 21 is pressed; when a power-on signal of a first preset duration is received, the output of the conduction control signal is maintained when the first button 21 is released; if no operation signal is received within a second preset duration, the output of the conduction control signal to the conduction control circuit 3 is stopped.

[0039] Specifically, when the first button 21 is not pressed and the first switch unit 11 is in the off state, the first switch unit 11 cannot output a power signal, and the control unit 4 cannot be powered on. When the first button 21 is pressed, the first button circuit 2 can form a grounding path, enabling the first switch unit 11 to conduct and output a power-on signal. When the first switch unit 11 is on, the negative terminal of the first switch unit 11 can output a power signal, so the control unit 4 can be powered on and start receiving external input signals to execute the corresponding action logic. When the first button 21 is still pressed, the first button circuit 2 can still output a power-on signal. When the control unit 4 is powered on, it can output a conduction control signal to the conduction control circuit 3 according to the power-on signal. Under normal use, the user will not press a button for too long and will always release the button. Therefore, the control unit 4 counts the output duration of the conduction control signal after outputting the conduction control signal.

[0040] When the duration of receiving the power-on signal is less than the first preset duration, the power-on signal disappears when the first button 21 is released. The control unit 4 does not output the conduction control signal, causing the first switch unit 11 to turn off, thus changing the control unit 4 from the power-on state back to the power-off state. When the duration of receiving the power-on signal reaches the first preset duration, the power-on signal disappears when the first button 21 is released, but the control unit 4 still outputs the conduction control signal, preventing the first switch unit 11 from being turned off, thus forming a power-on self-locking state. In the power-on self-locking state, the control unit 4 detects whether there is an input operation signal. If no operation signal is received within the second preset duration, it means that the user is not using the remote control. Therefore, the control unit 4 can actively stop the conduction control circuit 3 from outputting the conduction control signal, thereby causing the conduction control circuit 3 to control the first switch unit 11 to turn off, thus powering down the circuit and reducing power consumption to 0.

[0041] In one embodiment, the first switching unit 11 can be any electronic component with control pins, such as an NMOS transistor or a PMOS transistor, or it can be a combination unit composed of any electronic component with control pins and other electronic components (such as the first switching unit 11 formed by a PMOS transistor and a capacitor connected in parallel to the source and gate in this application), etc., and is not specifically limited here.

[0042] In one embodiment, the first button 21 can be a button in a remote control used to control other functions, or it can be a dedicated button used only for powering on, etc., and the specific method is not limited here.

[0043] In one embodiment, the conduction control circuit 3 can be a circuit based on logic gate chips, or a circuit based on switching units, etc., and is not specifically limited here.

[0044] In one embodiment, the control unit 4 can be one of the specific models of micro control unit (MCU) chips such as TC9012F, Holtek HT66F002, STC89C52RC, ESP32, etc., or it can be a unit composed of a specific model of micro control unit and peripheral circuits, etc., and the specific details are not limited here.

[0045] In one embodiment, the first preset duration can be a specific duration such as 2, 3, or 4 seconds, and is not specifically limited here. The second preset duration can also be a specific duration such as 2, 3, or 4 seconds, and is not specifically limited here. The first preset duration may be the same as or different from the second preset duration, and is not specifically limited here.

[0046] In one embodiment, the first button circuit 2 may include a first unidirectional circuit 22 and a second unidirectional circuit 23. The positive terminal of the first unidirectional circuit 22 may be connected in parallel with the positive terminal and the control terminal of the first switching unit 11, and the negative terminal of the first unidirectional circuit 22 may be connected to the first button 21. The first unidirectional circuit 22 may be used to control the first switching unit 11 to conduct when the first button 21 is pressed. The negative terminal of the second unidirectional circuit 23 may be connected to the first button 21, and the positive terminal of the second unidirectional circuit 23 may be connected to the control unit 4. The second unidirectional circuit 23 may be used to output a power-on signal when the first button 21 is pressed.

[0047] Specifically, when the first button 21 is pressed, the first one-way circuit 22 forms a closed circuit, generating a potential difference at the positive terminal of the first one-way circuit 22, thereby enabling the first switching unit 11 to conduct. The negative terminal of the second one-way circuit 23 is connected in parallel with the negative terminal of the first one-way circuit 22 to the first button 21. Therefore, when the first switching unit 11 is conducting, the negative terminals of both the first one-way circuit 22 and the second one-way circuit 23 are at a low level. Since the positive terminal of the second one-way circuit 23 is connected to the control unit 4, this low level is input to the control unit 4 as a power-on signal, causing the control unit 4 to output a conduction control signal.

[0048] In one embodiment, the unidirectional circuit may be composed of unidirectional devices (such as diodes), or a combination circuit composed of switching devices and electronic devices that enable the switching devices to conduct, etc., and is not specifically limited here.

[0049] For example, a unidirectional circuit includes a MOSFET and a resistor. The terminal of the MOSFET that receives current is the positive terminal, and the gate (G) terminal is the control terminal. A resistor is connected in parallel between the positive terminal and the control terminal. When the unidirectional circuit is open, the MOSFET will turn on automatically.

[0050] For another example, a unidirectional circuit includes a transistor and a resistor. The terminal from which current flows out of the transistor is the negative terminal, and a resistor is connected in parallel between the negative terminal and the control terminal. When the unidirectional circuit is open, the MOSFET will turn on automatically.

[0051] In one embodiment, the power consumption control circuit may further include a second button circuit 5, which includes a second button 51. The second button circuit 5 may be connected in parallel with the control unit 4 to the conduction control circuit 3. The second button circuit 5 may be used to output a shutdown control signal to the conduction control circuit 3 when the second button 51 is pressed. The conduction control circuit 3 may also be used to control the first switching unit to shut down when the shutdown control signal is received.

[0052] Specifically, the shutdown control signal and the power-on control signal are signals with opposite effects. During the process of the control unit 4 outputting the power-on control signal to the power-on control circuit 3, when the second button 51 is pressed, the second button circuit 5 will output a shutdown control signal to block the power-on control signal. At this time, the control unit 4 will still continue to output the power-on control signal, but the power-on control signal cannot reach the power-on control circuit 3; only the shutdown control signal can reach the power-on control circuit 3. When the first button 21 is not pressed, the power-on control circuit 3 can cause the first switch unit 11 to turn off under the action of the shutdown control signal, thereby stopping the first switch unit 11 from outputting power signals to the control unit 4. Therefore, the control unit 4 will be forcibly powered down. Because the addition of the second button circuit 5 allows the power consumption control circuit to have a forced power-down mechanism, when certain control functions on the remote control malfunction, pressing the second button 51 can force a power-down, thereby quickly reducing the impact of malfunctions and reducing the ineffective power consumption of the battery, thus effectively controlling the power consumption of the circuit.

[0053] In one embodiment, the power-on circuit 1 may include a voltage regulator circuit 12, which may be connected to the negative terminal of the first switching unit 11. The voltage regulator circuit 12 may be used to regulate the power signal output from the negative terminal of the first switching unit 11.

[0054] In one embodiment, the voltage regulator circuit 12 can be a circuit composed of one or more capacitors. When there are multiple capacitors, the multiple capacitors can be connected in series or in parallel, and no specific limitation is made here.

[0055] By setting a voltage regulator circuit 12 at the negative terminal of the first switching unit 11, the voltage of the power signal output by the first switching unit 11 can be stabilized at the voltage regulator circuit 12, thereby improving the quality of the power signal.

[0056] See Figure 2 , Figure 2 The circuit structure of the battery loading buffer circuit provided in the embodiment of this application is shown. In one embodiment, the power-on circuit 1 may further include a battery loading buffer circuit 13. The battery loading buffer circuit 13 may include an overcurrent protection circuit 131 and a second switching unit 132. The overcurrent protection circuit 131 is connected to the control terminal and the positive terminal of the second switching unit 132, respectively. The negative terminal of the second switching unit 132 is connected to the positive terminal of the first switching unit 11. The overcurrent protection circuit 131 can be used to provide grounding protection when an overcurrent occurs during battery loading, and to control the second switching unit 132 to conduct when no grounding protection is provided.

[0057] When the circuit is powered on with a battery and no overcurrent occurs, the overcurrent protection circuit 131 does not provide grounding protection. At this time, the second switching unit 132 can be turned on, making the path for the return current to the negative terminal of the battery open, thus enabling the circuit to function normally using the battery. When an overcurrent occurs, the overcurrent protection circuit 131 will perform protective grounding, and the second switching unit 132 will be turned off. At this time, the current flowing out of the power supply will flow directly to the ground terminal, thereby preventing the overcurrent from damaging the power consumption circuit.

[0058] In one embodiment, the overcurrent protection circuit 131 can be a circuit based on a reverse-connected Zener diode, or it can be a circuit based on a MOSFET (for example, introducing resistors at the two pins of GS based on the GS value, and checking whether there is an overcurrent in the circuit by whether the voltage difference between the two pins of GS is greater than the GS value), etc., and the specific method is not limited here.

[0059] In one embodiment, the overcurrent protection circuit 131 may include a voltage divider circuit 1311 and an overcurrent protection unit 1312. The voltage divider circuit 1311 is connected to the positive terminal of the first switching unit 11 and the positive terminal of the second switching unit 132, respectively. The voltage dividing point of the voltage divider circuit 1311 is connected to the control terminal of the second switching unit 132. The overcurrent protection unit 1312 is connected to the positive terminal of the second switching unit 132 and the voltage dividing point of the voltage divider circuit 1311.

[0060] By setting up a voltage divider circuit 1311 and connecting the control electrode of the second switching unit 132 to the voltage divider point of the voltage divider circuit 1311, it is possible to prevent the voltage input to the control electrode of the second switching unit 132 from being too high, which helps to reduce the probability of the second switching unit 132 being damaged.

[0061] In one embodiment, the voltage divider circuit 1311 may consist of two or more resistors. When the number of resistors is greater than two, the voltage divider points connected to the control electrodes of the overcurrent protection unit 1312 and the second switching unit 132 may be the same voltage divider point or different voltage divider points. No specific limitation is made here.

[0062] In one embodiment, the overcurrent protection unit 1312 can be a reverse-connected Zener diode, or it can be a combination unit formed by a reverse-connected Zener diode and other electronic devices, and the specific details are not limited here.

[0063] In one embodiment, the battery loading buffer circuit 13 may further include a spike pulse elimination circuit 1313, which is connected to the positive and negative terminals of the second switching unit 132 and can be used to absorb spike voltages.

[0064] By setting up a spike pulse cancellation circuit 1313, when external static electricity or spike pulse interference is input to the circuit, the spike pulse cancellation circuit 1313 can absorb the spike voltage, thereby reducing the interference of external static electricity or spike pulse interference to the circuit.

[0065] In one embodiment, the spike cancellation circuit 1313 can be a capacitor-based circuit, such as... Figure 2 In the embodiment shown, the spike pulse cancellation circuit 1313 includes a capacitor and a resistor. The capacitor can suppress spike voltage in a way that prevents voltage sudden changes, and the resistor can absorb spike voltage by dissipating heat.

[0066] To achieve the above objectives, embodiments of this application also provide a circuit board in a second aspect, the circuit board including the power consumption control circuit as described in any of the above embodiments.

[0067] To achieve the above objectives, in a third aspect, this application also provides a remote control, which includes a circuit board as described in the above embodiments.

[0068] To achieve the above objectives, the present application also provides a power-on control method in a fourth aspect, which is applied to the power consumption control circuit as described above. The method may include the following steps.

[0069] Step 310: When the control unit 4 is powered on and the first button circuit 2 outputs a power-on signal within a first preset time period, the control unit 4 outputs a conduction control signal to the conduction control circuit 3.

[0070] Step 320: The conduction control circuit 3 controls the first switching unit 11 to conduct based on the conduction control signal;

[0071] Step 330: When the control unit 4 does not receive any operation signal within the second preset time period, the control unit 4 stops outputting the conduction control signal of the conduction control circuit 3.

[0072] In one embodiment, the operation signal refers to the signal sent by the corresponding function button circuit to the control unit 4 after the function button of the remote control is pressed.

[0073] When the control unit 4 is powered on and has received a power-on signal for a first preset duration, the control unit 4 will output a conduction control signal to the conduction control circuit 3 to maintain the power-on self-locking state. However, users do not always use the remote control. To reduce power consumption, the remote control can be powered off during periods when the user is not using it. Specifically, after outputting the conduction control signal, the control unit 4 will detect whether there is an input operation signal. If no operation signal is received within a second preset duration, it means that the user is not using the remote control. Therefore, the control unit 4 can actively stop outputting the conduction control signal to the conduction control circuit 3, thereby causing the conduction control circuit 3 to control the first switching unit 11 to turn off, thus powering off the circuit and reducing power consumption to 0.

[0074] In one embodiment, the method may further include the following steps prior to step 310.

[0075] Step 410: When the control unit 4 is in a power-off state, the first button circuit 2 controls the first switch unit 11 to be turned on when the first button 21 is pressed, and outputs a power-on signal to the control unit 4.

[0076] Step 420: When the first switching unit 11 is turned on, it powers on the control unit 4.

[0077] In one embodiment, the method may further include the following steps.

[0078] Step 510: When the second button 51 is pressed, the conduction control circuit 3 outputs a power-on stop signal;

[0079] Step 520: The conduction control circuit 3 shuts off the first switch unit 11 according to the power-on stop signal;

[0080] Step 530: The first switching unit 11 powers down the control unit 4 when it is turned off.
