[0034] In the following description, specific details such as specific system structures, technologies, etc. are proposed for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the embodiments of the present application can also be implemented in other embodiments without these specific details.

Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0037] At present, smart door locks on the market generally include a normal mode for verifying unlock information and a management mode for configuring unlock information. Taking a smart door lock with a touch display panel as an example, to enter the management mode, it is generally necessary to first light up the display and then click the designated touch button. However, in this operation step, there is no threshold for lighting up the display and clicking the touch button, which means that anyone can perform the operation. This not only poses certain safety risks, but also causes unnecessary battery loss in the case that most smart door locks are powered by batteries.

[0038] Based on this, the embodiments of the present application provide a smart door lock and its control circuit, method, and computer-readable storage medium. In the control circuit of the smart door lock provided by the present application, the display module is in a power-off state for most of the time. Whether the display module is powered on is determined by the control module based on the comparison result between the touch input signal and the preset touch instruction. In this way, it can be avoided that anyone can light up the display screen. The display screen is only lit when it is really necessary to perform relevant operations through the display screen, thereby avoiding unnecessary loss of battery power of the smart door lock. This design does not conflict with the function of the smart door lock in normal mode, namely, verifying the unlocking information. That is, while ensuring that the smart door lock can realize its original function, the battery life of the battery-powered smart door lock is extended and the security of the smart door lock is improved to a certain extent.

[0039] The smart door lock and its control circuit, method, and computer-readable storage medium provided in the embodiments of the present application are specifically illustrated by the following embodiments. First, the control circuit of the smart door lock in the embodiments of the present application is described.

[0040] The present application embodiment provides a control circuit of a smart door lock. Figure 1 , Figure 1 A schematic diagram of a control circuit of a smart door lock provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, in this embodiment, the control circuit of the smart door lock includes: a power supply module 100, a touch module 200, a control module 300 and a display module 400;

[0041] The power supply module 100 is electrically connected to the touch module 200, the control module 300 and the display module 400 respectively, and the control module 300 is electrically connected to the touch module 200 and the display module 400 respectively;

[0042] The touch module 200 is used to generate a touch input signal according to the click operation detected within a first preset time period, and output the touch input signal to the control module 300;

[0043] The control module 300 is used to compare the touch input signal with the preset touch command to obtain a comparison result, and determine the working status of the touch module 200 and the display module 400 according to the comparison result.

[0044] It should be noted that the control circuit of the smart door lock provided in this embodiment can be applied to a smart door lock, and can also be applied to other electronic devices with similar functions to a smart door lock, and this embodiment does not limit this. For ease of understanding, this embodiment is described by taking the application of the control circuit of the smart door lock to a smart door lock as an example.

[0045] It should be noted that, in the present embodiment, the power supply module 100 may include a storage 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 touch module 200 may include a touch button panel, a touch sensor and a backlight panel. The touch button panel is used to receive a user's click operation, the touch sensor is used to detect a click action on the touch button panel and generate a corresponding touch input signal, and the backlight panel is used to light up the touch button panel so that the user can see the touch button clearly. Whether the backlight panel is lit can be configured by the control module 300, for example For example, it is not lit during the daytime, but is lit during the nighttime, or whether to light up depends on the ambient light intensity, etc. This embodiment does not limit this, and it should be noted that the touch module 200 does not necessarily include a backlight panel; the first preset time refers to a period of time that starts from when the touch module 200 receives a click operation from the user, such as a shorter period of time such as 5 seconds, 8 seconds, 10 seconds, etc. The first preset time can be set based on the time of the user's historical input of the permission instruction and the unlocking password, with the purpose of determining the touch input signal for expressing the user's operation intention within a reasonable time, avoiding power loss caused by the touch module 200 being in a standby state for a long time, thereby saving battery power; the control module 300 may include a low-power microcontroller unit (MCU, Microcontroller The microcontroller unit is used to receive the touch input signal from the touch module 200 and control the working state of the touch module 200 and the display module 400. The memory is used to store the preset touch instructions. The microcontroller unit can also be replaced by other types of processors or chips, as long as the same function can be achieved. This embodiment does not limit this. The display module 400 can include a display screen, which is in a power-off state by default. The display screen will be lit and display the picture only when the control module 300 allows the display module 400 to be powered on.

[0046] As an example, in this embodiment, the preset touch instruction can be regarded as a permission instruction for applying for lighting up the display screen. Taking the touch button panel containing numbers 0 to 9, the symbol * and the symbol # as an example, generally speaking, the password used to unlock the door is to enter a string of number combinations and then press # to end. In order to avoid conflicts between permission instructions and unlocking passwords, the preset touch instruction can be set to a string of instructions that starts with the symbol * and ends with the symbol #, such as *#, **#, *1#, etc. The permission instruction can also be set to other types of symbol and number combinations as long as it can avoid conflicts with the recognition method of the unlocking password. This embodiment does not limit this.

[0047] As an example, in this embodiment, the control module 300 may compare the touch input signal with the preset touch instruction by determining whether the two match. The simplest matching method is to determine whether the instruction information represented by the two is consistent. In addition, the comparison method may also be other reasonable methods. As long as a conclusion can be drawn based on the touch input signal and the preset touch instruction on whether to power on the display module or not, this embodiment does not impose any restrictions on this.

[0048] Reference Figure 2 In some feasible embodiments, the control circuit of the above-mentioned smart door lock may also include a sensing module 500, which is electrically connected to the power supply module 100 and the control module 300 respectively. The sensing module 500 is used to generate a sensing signal when a human body approaches, and output the sensing signal to the control module 300.

[0049] As an example, in this embodiment, the sensing module 500 may include a low-power 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, this embodiment does not limit this.

[0050] In this embodiment, when a sensing module 500 is added to the control circuit of the smart door lock, the standby strategies of the touch module 200 and the control module 300 can also be further adjusted, that is, only the sensing module 500 is kept in the standby state for a long time, and the touch module 200 and the control module 300 are in the power-off state. The control module 300 will be awakened from the power-off state and enter the power-on state only when it receives the sensing signal from the sensing module 500, and control the touch module 200 to enter the power-on state, so as to receive the external click operation and generate the corresponding touch input signal. That is to say, with the addition of the sensing module 500, there is no need to keep the touch module 200 and the control module 300 in standby mode around the clock. If no one approaches the smart door lock in standby mode, the sensing module 500 will not generate a sensing signal to wake up the control module 300, and the control module 300 will not wake up the touch module 200 to receive external click operations. In the long standby state, only the sensing module 500 with lower power consumption in the control circuit of the smart door lock consumes the electrical energy of the power supply module 100. Compared with the technical solutions in the related art that require each module to be in standby mode for a long time, the control circuit of the smart door lock proposed in this embodiment can save a lot of battery power.

[0051] 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 touch module 200. At this time, the control module 300 will be powered off again, and the touch module 200 and the display module 400 will also be powered off accordingly, thereby avoiding the touch module 200, the control module 300 and the display module 400 from consuming power in standby mode when not in use.

[0052] In this embodiment, by adding the sensing module 500 , the standby strategies of the touch module 200 and the control module 300 can be improved simultaneously, thereby further saving power consumption and extending the battery life.

[0053] In some feasible embodiments, the control module 300 is used to control the touch module 200 and the display module 400 to be in a power-on state when the comparison result is that the touch input signal successfully matches the preset touch instruction.

[0054] In this embodiment, if the touch input signal successfully matches the preset touch command, it means that the current user does have a need to light up the display screen (to enter the management mode). Therefore, the control module 300 can keep the touch module 200 in the powered-on state and control the display module 400 to switch from the powered-off state to the powered-on state, so that the touch module 200 can normally receive subsequent click operations from the user within a certain period of time, and the display module 400 can also light up the display screen and then normally display the relevant screen; it can be understood that even if the touch input signal matches the preset touch command, If the instruction matches successfully, the control module 300 will not control the touch module 200 and the display module 400 to be in the power-on state all the time, resulting in continuous loss of battery power. That is, a duration can also be configured for the power-on state, such as 30 seconds, 50 seconds, 1 minute, etc. If the control module 300 has not received the touch input signal from the touch module 200 after the display module 400 is powered on, it means that the user has not performed any further operation. Therefore, after the power-on time of the display module 400 reaches the duration, the display module 400 can be controlled to be powered off to avoid wasting battery power.

[0055] In some feasible embodiments, the control module 300 is used to control the touch module 200 to be in a power-off state for a second preset time period and control the display module 400 to be in a power-off state when the comparison result is that the touch input signal fails to match the preset touch instruction, wherein the second preset time period is greater than the first preset time period.

[0056] In this embodiment, if the touch input signal fails to match the preset touch command, it means that the touch input signal is incorrect. For safety reasons, the touch module 200 can be controlled to directly power off for a second preset time, such as 1 minute, 1.5 minutes, 2 minutes or other longer time (generally speaking, as long as it is greater than the first preset time and can reflect the time difference between the two scenarios, this embodiment is not limited to this), to avoid the operator from meaninglessly consuming the battery power of the power supply module 100; in addition, in order to ensure a certain input fault tolerance, an audio output module can be added to the control circuit of the smart door lock, and the control module 300 can be added with a control logic, that is, after a matching failure, the audio output module is controlled to output A prompt sound is emitted to prompt the operator to perform the click operation again. At the same time, the touch module 200 is controlled to receive the click operation within a certain period of time again and generate a new touch input signal based on it. Then, the control module 300 compares the new touch input signal with the preset touch instruction until the matching failure (or continuous matching failure) reaches a certain number of times. Then, the touch module 200 is controlled to be in a power-off state within a second preset period of time. However, this method of providing input fault tolerance can improve the user experience to a certain extent, but compared with the solution that does not provide fault tolerance, its power consumption will also increase. The specific method to be selected for control can be flexibly configured according to actual conditions, and this embodiment does not limit this.

[0057] This embodiment provides a control circuit for a smart door lock. In the standby state, only the sensing module with low power consumption consumes the power of the power supply module, and the touch module, control module and display module are all powered off and do not work. The control module will be awakened only after the sensing signal is generated, and then the touch module is awakened. The display module requires the control module to further determine whether to power on by combining the touch input signal from the touch module and the preset touch command. This embodiment does not affect the original function of the smart door lock that can use the control circuit of the smart door lock, avoids unnecessary loss of battery power of the smart door lock, and significantly reduces the overall power consumption of the smart door lock in the standby state, prolongs the battery life of the smart door lock powered by the battery, and improves the safety of the smart door lock to a certain extent.

[0058] In addition, the present application also provides a control method for a smart door lock, referring to Figure 3 , Figure 3 A flow chart of a control method of a smart door lock provided in an embodiment of the present application is provided.

[0060] Step S20: Compare the touch input signal with the preset touch command to obtain a comparison result, and determine the working status of the touch module and the display module according to the comparison result.

[0061] In this embodiment, the execution subject is a control module in the control circuit of the smart door lock provided in the above embodiment.

[0062] In some feasible embodiments, the control circuit of the smart door lock further includes a sensing module, which is electrically connected to the power supply module and the control module respectively; Figure 4 Before the above step S10, the control method of the smart door lock may further include:

[0063] Step S01, receiving a sensing signal generated by a sensing module when a human body approaches, and powering on based on the sensing signal.

[0064] It can be understood that in this embodiment, the control module is in a power-off state when no sensing signal is received, does not consume the battery power in the power supply module, and 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.

[0065] Reference Figure 5 In some feasible embodiments, the above step S20 may specifically include:

[0066] Step S21 , when the comparison result is that the touch input signal successfully matches the preset touch instruction, the touch module and the display module are controlled to be in a power-on state.

[0067] In some feasible embodiments, the above step S20 may specifically include:

[0068] Step S22, when the comparison result is that the touch input signal fails to match the preset touch instruction, the touch module is controlled to be in a power-off state for a second preset time length, and the display module is controlled to be in a power-off state, wherein the second preset time length is greater than the first preset time length.
