[0039] As smart cat-eyes become more popular, more and more people are beginning to pay attention to their battery life. Since most smart cat-eye products on the market need to remain in standby mode 24 / 7, even if a large-capacity lithium battery is used as the power supply, the battery life it can support still cannot meet the needs of some users, and an external power supply requires additional wiring, which will significantly increase the complexity and cost of installing the product.

[0040] Based on this, the embodiments of the present application provide a power supply management circuit, method, smart cat's eye and computer-readable storage medium, which effectively improves the battery life of the smart cat's eye by optimizing the circuit design and power supply strategy. In the standby state, only the sensing module with lower power consumption consumes the power of the power supply module, and the control module, acquisition module and display module are all powered off and do not work. The control module will only be awakened after the sensing signal is generated, and the acquisition module and the display module require the control module to further determine whether to power on in combination with the sensing signal. The embodiments of the present application do not affect the smart cat's eye that can use the power supply management circuit to realize the original function, and significantly reduce the overall power consumption of the product in the standby state, and extend the battery life without replacing the power supply.

[0041] The power supply management circuit, method, smart cat eye and computer-readable storage medium provided in the embodiments of the present application are specifically illustrated through the following embodiments. First, the power supply management circuit in the embodiments of the present application is described.

[0042] The present application embodiment provides a power supply management circuit, referring to Figure 1 , Figure 1 A schematic diagram of a power supply management circuit provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, in this embodiment, the power supply management circuit includes: a power supply module 100, a sensing module 200, a control module 300, a switch module 400, a collection module 500 and a display module 600;

[0043] The power supply module 100 is electrically connected to the first ends of the sensing module 200, the control module 300 and the switch module 400 respectively, the sensing module 200 is electrically connected to the control module 300, the control module 300 is electrically connected to the controlled end of the switch module 400, the second end of the switch module 400 is electrically connected to the acquisition module 500 and the display module 600 respectively, and the acquisition module 500 is electrically connected to the display module 600;

[0044] The sensing module 200 is used to generate a sensing signal when detecting a human body approaching, and output the sensing signal to the control module 300;

[0045] The control module 300 is used to power on and wake up when receiving a sensing signal, and control the on / off state of the switch module 400 according to the sensing signal.

[0046] It should be noted that the power supply management circuit provided in this embodiment can be applied to a smart cat eye, a smart door lock combined with a smart cat eye, or other electronic devices installed on a door with similar functional modules, and this embodiment does not limit this. For ease of understanding, this embodiment uses the application of the power supply management circuit to a smart cat eye as an example for explanation.

[0047] It should be noted that, in this embodiment, the power supply module 100 may include a battery (including but not limited to a lithium battery) as a power source and a voltage converter for converting the power supply voltage into an operating voltage. It is understandable that the operating voltages adapted to different functional modules are generally different. Therefore, the power supply module 100 may include multiple voltage converters for converting different operating voltages for powering on each functional module; the sensing module 200 may include an infrared sensor, a proximity sensor, or other types of sensors, as long as it can detect the event of a human body approaching and generate a corresponding sensing signal, and this embodiment does not limit this; the control module 300 may be a low-power micro The controller may also be other types of processors or chips, as long as it meets the condition that power-on must be enabled by an induction signal, and this embodiment does not limit this; the switch module 400 may include any type of switching device, as long as it can change its on-off state under the control of the control module 300, and this embodiment does not limit this; the acquisition module 500 may be any type of camera module, which is used to acquire the real-time scene outside the door after power-on and generate a video stream based on the real-time scene outside the door, and output the video stream to the display module 600; the display module 600 may be any type of display module, which is used to output a display screen containing the real-time scene outside the door according to the video stream after power-on.

[0048] It should be emphasized that in the present embodiment, the switch module 400 is usually in a disconnected state when it is not controlled by the control module 300, that is, the electric energy provided by the power supply module 100 will only be transmitted to the sensing module 200 and the control module 300, wherein the control module 300 cannot be powered on and work without receiving the sensing signal, and will not consume power. In other words, even if the smart cat's eye using the power supply management circuit needs to maintain a standby state around the clock, if no one approaches the smart cat's eye in the standby state, the sensing module 200 will not generate a sensing signal to wake up the control module 300. Only the sensing module 200 with lower power consumption in the power supply management circuit consumes the electric energy of the power supply module 100. Therefore, the power supply management circuit can save the electric energy wasted by the control module 300, the acquisition module 500 and the display module 600 when they are powered on and in standby state without the need to capture and display images.

[0049] It is understandable that after the control module 300 is powered on due to the sensing signal, as long as the sensing signal disappears, it means that the human body has moved away from the sensing distance of the sensing module 200. At this time, the control module 300 will be powered off again, and the switch module 400 will be turned off accordingly, thereby avoiding the control module 300, the acquisition module 500 and the display module 600 from consuming power in standby mode when not in use.

[0050] Reference Figure 2 In some feasible embodiments, the switch module 400 includes:

[0051] A first switch unit 401, wherein a first end of the first switch unit 401 is electrically connected to the power supply module 100, a controlled end of the first switch unit 401 is electrically connected to the control module 300, and a second end of the first switch unit 401 is electrically connected to the acquisition module 500;

[0052] The second switch unit 402 , a first end of the second switch unit 402 is electrically connected to the power supply module 100 , a controlled end of the second switch unit 402 is electrically connected to the control module 300 , and a second end of the second switch unit 402 is electrically connected to the display module 600 .

[0053] In this embodiment, an optional implementation of the switch module 400 is proposed, that is, it is divided into two different switch units, the first switch unit 401 is used to turn on or off the path between the power supply module 100 and the acquisition module 500, and the second switch unit 402 is used to turn on or off the path between the power supply module 100 and the acquisition module 500.

[0054] In some feasible embodiments, the control module 300 is used to control the first switch unit 401 to be turned on when the sensing signal includes an outside-door sensing signal.

[0055] In some feasible embodiments, the control module 300 is used to control the first switch unit 401 and the second switch unit 402 to be turned on when the sensing signal includes an outside-door sensing signal and an inside-door sensing signal.

[0056] It should be noted that, in this embodiment, the sensing module 200 may include a part arranged outside the door and a part arranged inside the door, which are respectively used to detect whether there is a human body approaching outside the door and inside the door. Therefore, the sensing signal in this embodiment may include an outside-door sensing signal and an inside-door sensing signal.

[0057] It is understandable that, in the case where the sensing signal only includes the sensing signal outside the door, only the first switch unit 401 can be turned on to enable the acquisition module 500 to be powered on, thereby performing image acquisition or face recognition on the person outside the door, thereby avoiding the situation where the second switch unit 402 is turned on to enable the display module 600 to be powered on but there is no one inside the door to check, resulting in unnecessary waste of power.

[0058] It can be understood that, in the case where the sensing signal includes both the sensing signal outside the door and the sensing signal inside the door, the first switch unit 401 and the second switch unit 402 can be controlled to be turned on, so that the acquisition module 500 and the display module 600 are both powered on and perform corresponding functions. At this time, the display screen displayed by the display module 600 can be seen by the person inside the door, which can reflect the significance of the display module 600 being powered on.

[0059] In addition, for the case where the sensing signal only includes the sensing signal inside the door, it may be that the person inside the door has a need to view the real-time scene outside the door through the display module 600, so the first switch unit 401 and the second switch unit 402 can be controlled to be turned on so that the acquisition module 500 and the display module 600 are both powered on and working; but it may also be that the person inside the door just wants to go out and there is no need to view the real-time scene outside the door, so the first switch unit 401 and the second switch unit 402 can be controlled to be turned off, and the acquisition module 500 and the display module 600 are not enabled to avoid wasting power; therefore, for the case where the sensing signal only includes the sensing signal inside the door, the corresponding power-on logic can be set according to actual needs, and this embodiment does not limit this.

[0060] In addition, refer to Figure 3 In some feasible embodiments, another variation of the power supply management circuit is provided, that is, the control module 300 does not directly enable power-on based on the sensing signal, but a switch is added between the power supply module 100 and the control module 300, and the sensing module 200 is electrically connected to the controlled end of the switch. The switch is turned on when the sensing signal is received, and is turned off when the sensing signal is not received. This can also achieve technical effects that are basically the same as the solution in which the control module 300 is awakened and powered on by the sensing signal as recorded in the above embodiment.

[0061] In addition, refer to Figure 4 In some feasible embodiments, another variation of the power supply management circuit is provided, that is, the switch module 400 is omitted, and the acquisition module 500 and the display module 600 are directly enabled and controlled according to the sensing signal by the control module 300, which can also achieve a technical effect that is basically the same as the solution recorded in the above embodiment of determining whether the acquisition module 500 and the display module 600 are powered on by controlling the switch module 400.

[0062] This embodiment provides a power supply management circuit. In the standby state, only the sensing module with low power consumption consumes the power of the power supply module. The control module, the acquisition module and the display module are all powered off and do not work. The control module will be awakened only after the sensing signal is generated. The acquisition module and the display module require the control module to further determine whether to power on in combination with the sensing signal. This embodiment does not affect the original functions of the smart cat's eye that can use the power supply management circuit, and significantly reduces the overall power consumption of the product in the standby state, extending the battery life without replacing the power supply.

[0063] In addition, the present application also provides a power supply management method, referring to Figure 5 , Figure 5 A schematic diagram of a power supply management method provided in an embodiment of the present application is provided. The power supply management method can be applied to smart cat eyes, such as Figure 5 As shown, the power supply management method provided in this embodiment includes step S10 and step S20 executed by the control module in the power supply management circuit provided in the above embodiment.

[0064] Step S10, receiving a sensing signal generated by the sensing module when a human body is detected approaching;

[0065] Step S20, controlling the on / off state of the switch module according to the sensing signal.

[0066] It should be noted that, in this embodiment, the executing body is the control module in the power supply management circuit provided in the above embodiment. The control module is in a power-off state when no sensing signal is received, and does not consume the battery power in the power supply module. It is powered on and awakened only when a sensing signal is received. The sensing signal can be regarded as an enable signal of the control module. At the same time, the sensing signal can also provide the control module with key information on how to control the switch module, that is, whether there is someone approaching inside or outside the door.

[0067] In some feasible embodiments, the switch module includes a first switch unit and a second switch unit, a first end of the first switch unit is electrically connected to the power supply module, a controlled end of the first switch unit is electrically connected to the control module, a second end of the first switch unit is electrically connected to the acquisition module, a first end of the second switch unit is electrically connected to the power supply module, a controlled end of the second switch unit is electrically connected to the control module, and a second end of the second switch unit is electrically connected to the display module;

[0068] The above step S20 may specifically include:

[0069] Step S21, controlling the on / off state of the first switch unit and / or the second switch unit according to the sensing signal.

[0070] It can be understood that in this embodiment, the control module can choose to control only the on-off state of the first switch unit, or only the on-off state of the second switch unit, or both the on-off state of the first switch unit and the on-off state of the second switch unit according to the specific type of the sensing signal.

[0071] In some feasible embodiments, the above step S21 may specifically include:

[0072] Step S211: when the sensing signal includes an outside door sensing signal, control the first switch unit to be turned on.

[0073] In some feasible embodiments, the above step S21 may further include:

[0074] Step S212: When the sensing signal includes an outside-door sensing signal and an inside-door sensing signal, the first switch unit and the second switch unit are controlled to be turned on.

[0075] It should be noted that, in this embodiment, the sensing module may include a part arranged outside the door and a part arranged inside the door, which are respectively used to detect whether there is a human body approaching outside the door and inside the door. Therefore, the sensing signal in this embodiment may include an outside-door sensing signal and an inside-door sensing signal.

[0076] It can be understood that, when the sensing signal only includes the sensing signal outside the door, only the first switch unit can be turned on to enable the acquisition module to be powered on, and then image acquisition or face recognition of the person outside the door can be performed, thereby avoiding the situation where the second switch unit is turned on to enable the display module to be powered on but there is no one inside the door to check, resulting in unnecessary waste of power.

[0077] It can be understood that when the sensing signal includes both the sensing signal outside the door and the sensing signal inside the door, the first switch unit and the second switch unit can be controlled to be turned on, so that the acquisition module and the display module are both powered on and perform corresponding functions. At this time, the display screen displayed by the display module can be seen by the person inside the door, which can reflect the significance of the display module being powered on.

[0078] In addition, for the case where the sensing signal only includes the sensing signal inside the door, it may be that the person inside the door has a need to view the real-time scene outside the door through the display module, so the first switch unit and the second switch unit can be controlled to be turned on so that both the acquisition module and the display module are powered on; but it may also be that the person inside the door just wants to go out and there is no need to view the real-time scene outside the door, so the first switch unit and the second switch unit can be controlled to be turned off, and the acquisition module and the display module are not enabled to avoid wasting power; therefore, for the case where the sensing signal only includes the sensing signal inside the door, the corresponding power-on logic can be set according to actual needs, and this embodiment does not limit this.
