DETAILED DESCRIPTION
[0018] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

The terms "first," "second," and so on, in the specification, claims, and drawings, are used to distinguish similar items and are not necessarily used to describe a specific sequence or precedence.
[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.
[0021] With the widespread adoption and development of IoT consumer electronics and industrial control equipment, users are placing higher demands on remote controls for operating these devices. Traditional infrared remote controls have limitations such as high directivity requirements, limited functionality, and susceptibility to environmental interference. These limitations make them unable to meet the multifunctional, long-range, and highly reliable operation demands of modern devices. Consequently, second-generation ZigBee, Wi-Fi, and BLE wireless communication remote control technologies have been developed and applied. However, these new technologies also present challenges, particularly for portable, handheld, battery-powered devices. Insufficient battery life can negatively impact user experience.
[0022] In order to reduce the power consumption of a remote control, an embodiment of the present application provides a power consumption control circuit, a circuit board, a remote control and a power-on control method, wherein the circuit includes a power-on circuit, including a first switch unit; a first key circuit, including a first key, the first key circuit is connected in parallel to the positive pole and the control pole of the first switch unit, and the first key circuit is used to output a power-on signal and control the first switch unit to be turned on when the first key is pressed; a conduction control circuit, connected in parallel to the positive pole and the control pole of the first switch unit, and the conduction control circuit is used to control the conduction of the first switch unit when a conduction control signal is received; a control unit, respectively connected to the negative pole of the first switch unit, the first key circuit and the conduction control circuit, and the control unit is used to output a conduction control signal to the conduction control circuit according to the power-on signal when the first key is pressed; when the power-on signal of the first preset duration is received, when the first button is released, the conduction control signal is kept output; if no operation signal is received within a second preset duration, the conduction control signal is stopped from being output to the conduction control circuit. Because the circuit only powers on when the first button is pressed and only self-locks when the power-on signal is generated for a first preset duration, the circuit only consumes power when it is in use, helping to reduce startup power consumption caused by accidental touches of the remote control. Furthermore, because the control unit stops outputting the conduction control signal to the conduction control circuit if it does not receive any operation signal within a second preset duration, the circuit can be directly powered off, eliminating any power consumption during standby mode. This effectively reduces standby power consumption and further reduces the overall power consumption of the remote control.
[0023] See also Figure 1 , Figure 1 The circuit structure of the power consumption control circuit provided in an embodiment of the present application is shown. In the embodiment of the present 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.
[0024] The power-on circuit 1 may include a first switch unit 11; the first key circuit 2 may include a first key 21. The first key circuit 2 may be connected in parallel to the positive electrode and control electrode of the first switch unit 11. The first key circuit 2 may be configured to output a power-on signal and control the first switch unit 11 to conduct when the first key 21 is pressed. The conduction control circuit 3 may be connected in parallel to the positive electrode and control electrode of the first switch unit 11. The conduction control circuit 3 may be configured to control the first switch unit 11 to conduct when it receives a conduction control signal. The control unit 4 may be connected to the negative electrode of the first switch unit 11, the first key circuit 2, and the conduction control circuit 3, respectively. The control unit 4 may be configured to output a conduction control signal to the conduction control circuit 3 based on the power-on signal when the first key 21 is pressed; upon receiving a power-on signal for a first preset duration, the control unit 4 may maintain output of the conduction control signal when the first key 21 is released; and upon receiving no operation signal for a second preset duration, the control unit 4 may cease outputting the conduction control signal to the conduction control circuit 3.
[0025] 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 ground path, allowing 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, and the control unit 4 can then be powered on by the power signal and begin 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 in the powered-on state, it can output a conduction control signal to the conduction control circuit 3 based on the power-on signal. Under normal use, users do not press a button for too long and will always release it. Therefore, the control unit 4 counts the output duration of the conduction control signal after outputting the conduction control signal.
[0026] When the duration of receiving the power-on signal does not reach the first preset duration, when the first button 21 is released, the power-on signal will disappear, and the control unit 4 will not output the conduction control signal, causing the first switch unit 11 to be turned off, so that the control unit 4 changes from the power-on state to the power-off state. When the duration of receiving the power-on signal reaches the first preset duration, when the first button 21 is released, the power-on signal will disappear, but the control unit 4 will still output the conduction control signal, so that the first switch unit 11 will not be turned off, thereby forming a power-on self-locking state. When in the power-on self-locking state, the control unit 4 will detect whether there is an input of an operation signal. When no operation signal is received within the second preset duration, it indicates 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, so that the conduction control circuit 3 can control the first switch unit 11 to turn off, thereby powering off the circuit and reducing power consumption to 0.
[0027] In one embodiment, the first switch unit 11 can be any electronic component with a control pin, such as an NMOS tube, a PMOS tube, etc., or a combination unit composed of any electronic component with a control pin and other electronic components (such as the first switch unit 11 formed by the PMOS tube and the capacitor connected in parallel to the source and gate in this application), etc., which is not specifically limited here.
[0028] In one embodiment, the first button 21 may be a button in a remote controller for controlling other functions, or a dedicated button only for powering on, etc., which is not specifically limited here.
[0029] In one embodiment, the conduction control circuit 3 may be a circuit based on a logic gate chip, or a circuit based on a switch unit, etc., which is not specifically limited here.
[0030] In one embodiment, the control unit 4 may be one of the micro control unit (MCU) chips of specific models such as TC9012F, Holtek HT66F002, STC89C52RC, ESP32, or may be a unit composed of a micro control unit of a specific model and peripheral circuits, etc., which is not specifically limited here.
[0031] In one embodiment, the first preset duration can be a specific duration such as 2, 3, or 4 seconds, which is not specifically limited herein. The second preset duration can be a specific duration such as 2, 3, or 4 seconds, which is not specifically limited herein. The first preset duration can be equal to or different from the second preset duration, which is not specifically limited herein.
[0032] In one embodiment, the first button circuit 2 may include a first unidirectional circuit 22 and a second unidirectional circuit 23. The positive electrode of the first unidirectional circuit 22 may be connected in parallel to the positive electrode and the control electrode of the first switch unit 11, and the negative electrode of the first unidirectional circuit 22 is connected to the first button 21. The first unidirectional circuit 22 may be used to control the first switch unit 11 to be conductive when the first button 21 is pressed. The negative electrode of the second unidirectional circuit 23 is connected to the first button 21, and the positive electrode of the second unidirectional circuit 23 is 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.
[0033] Specifically, when the first button 21 is pressed, the first unidirectional circuit 22 forms a path, generating a potential difference at the positive electrode of the first unidirectional circuit 22, thereby enabling the first switch unit 11 to be turned on. The negative electrode of the second unidirectional circuit 23 is connected in parallel with the negative electrode of the first unidirectional circuit 22 to the first button 21. Therefore, when the first switch unit 11 is able to be turned on, the negative electrodes of the first unidirectional circuit 22 and the second unidirectional circuit 23 are both at a low level, while the positive electrode of the second unidirectional circuit 23 is connected to the control unit 4. Then, the low level is input into the control unit 4 as a power-on signal, causing the control unit 4 to output a conduction control signal.
[0034] In one embodiment, the unidirectional circuit may be composed of a unidirectional device (such as a diode), or a combination circuit composed of a switching device and an electronic device that turns on the switching device, etc., which is not specifically limited here.
[0035] For example, a unidirectional circuit includes a MOS tube and a resistor. The electrode where the current flows into the MOS tube serves as the positive electrode, the G electrode serves as the control electrode, and a resistor is connected in parallel between the positive electrode and the control electrode. When the unidirectional circuit is a passage, the MOS tube will turn on by itself.
[0036] For another example, a unidirectional circuit includes a transistor and a resistor. The electrode of the transistor where the current flows out serves as the negative electrode, and a resistor is connected in parallel between the negative electrode and the control electrode. When the unidirectional circuit is a passage, the MOS tube will turn on by itself.
[0037] In one embodiment, the power consumption control circuit may further include a second button circuit 5, the second button circuit 5 includes a second button 51, the second button circuit 5 can be connected in parallel with the conduction control circuit 3 together with the control unit 4, the second button circuit 5 can be used to output a shutdown control signal to the conduction control circuit 3 when the second button 51 is pressed, and the conduction control circuit 3 can also be used to control the first switch unit to shut down when receiving the shutdown control signal.
[0038] Specifically, the off control signal and the on control signal are signals with opposite effects. When the control unit 4 outputs the on control signal to the conduction control circuit 3, if the second button 51 is pressed, the second button circuit 5 will output the off control signal to block the on control signal. At this time, the control unit 4 will continue to output the on control signal, but the on control signal cannot reach the conduction control circuit 3. Only the off control signal can reach the conduction control circuit 3. When the first button 21 is not pressed, the conduction control circuit 3 will, under the action of the off control signal, turn off the first switch unit 11, thereby causing the first switch unit 11 to stop outputting the power signal to the control unit 4. Then, the control unit 4 will be forced to power off. Due to the addition of the second button circuit 5, the power consumption control circuit can have a forced power-off mechanism. Therefore, when certain control functions on the remote control malfunction, the second button 51 can be pressed to force the power off, thereby quickly reducing the impact of the malfunction and reducing the ineffective power consumption of the battery due to the malfunction, thereby effectively controlling the power consumption of the circuit.
[0039] In one embodiment, the power-on circuit 1 may include a voltage stabilizing circuit 12 , which may be connected to the cathode of the first switch unit 11 . The voltage stabilizing circuit 12 may be used to stabilize the power signal outputted from the cathode of the first switch unit 11 .
[0040] In one embodiment, the voltage stabilizing circuit 12 may be a circuit composed of one or more capacitors. In the case of multiple capacitors, the multiple capacitors may be connected in series or in parallel, which is not specifically limited here.
[0041] By arranging the voltage stabilizing circuit 12 at the negative electrode of the first switch unit 11 , the voltage of the power signal output by the first switch unit 11 can be stabilized at the voltage stabilizing circuit 12 , thereby improving the quality of the power signal.
[0042] See also Figure 2 , Figure 2 The circuit structure of the battery loading buffer circuit provided in an embodiment of the present 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 switch unit 132. The overcurrent protection circuit 131 is respectively connected to the control electrode and the positive electrode of the second switch unit 132. The negative electrode of the second switch unit 132 is connected to the positive electrode of the first switch unit 11. The overcurrent protection circuit 131 can be used to perform grounding protection when an overcurrent is generated during battery loading, and to control the second switch unit 132 to be turned on when grounding protection is not performed.
[0043] When the circuit is powered by a battery and no overcurrent is occurring, overcurrent protection circuit 131 is not grounded. Second switch unit 132 can be turned on, completing the path for current to flow back to the negative terminal of the battery, allowing the circuit to function normally using the battery. If an overcurrent condition occurs, overcurrent protection circuit 131 grounds the circuit, disconnecting second switch unit 132. Current flowing from the power supply now flows directly to ground, preventing damage to the power-consuming circuit from the overcurrent.
[0044] In one embodiment, the overcurrent protection circuit 131 can be a circuit formed based on a reverse-connected voltage-stabilizing diode, or a circuit formed based on a MOS tube (for example, a resistor is introduced at the two gs pins based on the gs value, and whether the voltage difference between the two gs pins is greater than the gs value is used to detect whether the circuit has overcurrent), etc., which is not specifically limited here.
[0045] 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 electrode of the first switch unit 11 and the positive electrode of the second switch unit 132, respectively. The voltage divider point of the voltage divider circuit 1311 is connected to the control electrode of the second switch unit 132. The overcurrent protection unit 1312 is connected to the positive electrode of the second switch unit 132 and the voltage divider point of the voltage divider circuit 1311.
[0046] By providing the voltage divider circuit 1311 and connecting the control electrode of the second switch unit 132 to the voltage dividing point of the voltage divider circuit 1311 , the voltage input to the control electrode of the second switch unit 132 can be prevented from being too high, which helps to reduce the probability of the second switch unit 132 being damaged.
[0047] In one embodiment, the voltage divider circuit 1311 can be composed of two or more resistors. When the number of resistors is greater than two, the voltage divider point connected to the control electrode of the overcurrent protection unit 1312 and the second switch unit 132 can be the same voltage divider point or different voltage divider points, which is not specifically limited here.
[0048] In one embodiment, the overcurrent protection unit 1312 may be a reverse-connected voltage regulator diode, or a combination unit formed by a reverse-connected voltage regulator diode and other electronic devices, which is not specifically limited here.
[0049] In one embodiment, the battery loading buffer circuit 13 may further include a spike elimination circuit 1313 . The spike elimination circuit 1313 is connected to the positive electrode and the negative electrode of the second switch unit 132 . The spike elimination circuit 1313 may be used to absorb spike voltage.
[0050] By providing the spike elimination circuit 1313 , when external static electricity or spike interference is input into the circuit, the spike elimination circuit 1313 can absorb the spike voltage, thereby reducing the interference of the external static electricity or spike interference on the circuit.
[0051] In one embodiment, the spike elimination circuit 1313 may be a circuit composed of capacitors, such as Figure 2 In the embodiment shown in FIG, the spike pulse elimination circuit 1313 may include a capacitor and a resistor. The capacitor may suppress the spike voltage by preventing voltage mutation, and the resistor may absorb the spike voltage by dissipating heat.
[0052] In order to achieve the above-mentioned purpose, an embodiment of the present application further provides a circuit board in a second aspect, and the circuit board includes the power consumption control circuit as described in any of the above-mentioned embodiments.
[0053] In order to achieve the above-mentioned purpose, the embodiments of the present application further provide a remote control in a third aspect, and the remote control includes the circuit board as described in the above-mentioned embodiments.
[0054] In order to achieve the above-mentioned purpose, an embodiment of the present application further provides a power-on control method in a fourth aspect, which is applied to the power consumption control circuit as mentioned above. The method may include the following steps.
[0055] Step 310: When the control unit 4 is in a powered-on state and the first key 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; Step 320: The conduction control circuit 3 controls the first switch unit 11 to be turned on based on the conduction control signal; 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 to the conduction control circuit 3 .
[0056] In one embodiment, the operation signal refers to a signal sent by the corresponding function button circuit to the control unit 4 after a function button of the remote controller is pressed.
[0057] When the control unit 4 is in the power-on state and receives a power-on signal of the 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, the user does not always use the remote control. In order to reduce power consumption, the remote control can be powered off during the period when the user is not using the remote control. Specifically, after outputting the conduction control signal, the control unit 4 will detect whether there is an input of an 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 outputting the conduction control signal to the conduction control circuit 3, so that the conduction control circuit 3 can control the first switch unit 11 to turn off, thereby powering off the circuit and reducing power consumption to 0.
[0058] In one embodiment, before step 310 , the method may further include the following steps.
[0059] 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; Step 420 : When the first switch unit 11 is turned on, the control unit 4 is powered on.
[0060] In one embodiment, the method may further include the following steps.
[0061] Step 510: The second button circuit 5 outputs a power-on stop signal to the conduction control circuit 3 when the second button 51 is pressed; Step 520: the conduction control circuit 3 turns off the first switch unit 11 according to the power-on stop signal; Step 530 : When the first switch unit 11 is turned off, the control unit 4 is powered off.
