[0001] The present application relates to the field of intelligent lock control, and specifically to a control method for an intelligent electronic lock and an intelligent electronic lock. Background Art

[0002] Currently, smart electronic locks, such as smart door locks, are generally driven by motors. To control a smart electronic lock, it is first necessary to obtain the operating status and rotational position of the motor driving it, and then further drive and control the smart electronic lock.

[0003] When using a stepper motor, due to its characteristics, its rotation state and rotation angle and other parameters can be directly obtained. However, due to cost control, the motor used in smart electronic locks is usually a DC motor.

[0004] Compared to stepper motors, DC motors have lower rotational coordinate accuracy. Existing technical solutions typically use auxiliary devices such as Hall effect devices and infrared sensors in the motor drive control design to detect and process the door lock control status to achieve rotational position calibration. However, the use of auxiliary devices requires additional, costly computational logic and investment. Summary of the Invention

[0005] Based on this, the present application provides a control method for an intelligent electronic lock that eliminates the need for auxiliary devices and can determine the motor's operating status and rotational position simply by measuring the DC motor's current. Specifically, the present application improves the DC motor drive circuit, monitors the DC motor's real-time current data, analyzes and processes the collected data, and thus infers the operating status of the intelligent electronic lock.

[0006] According to one aspect of the present application, a control method for a smart electronic lock is provided, wherein the smart electronic lock is driven by a DC motor, and the method comprises:

[0007] Obtaining a temporal distribution result of a sampled current value of the DC motor;

[0008] Based on the temporal distribution result of the sampled current value and the preset state current value and state time value, the operating state of the smart electronic lock is obtained;

[0009] Based on the operating status, the smart electronic lock is controlled.

[0010] According to some embodiments, the state current value includes a starting current value, a rotation process current value, and a rotation position current value.

[0011] According to some embodiments, the status time value includes a start timeout value, a rotation timeout value, and a rotation-to-position timeout value.

[0012] According to some embodiments, the aforementioned method also includes: if the sampling current value is equal to the starting current value, and the duration of the sampling current value being equal to the starting current value is less than the starting timeout value, it is judged that the smart electronic lock is in the starting state; if the sampling current value is equal to the starting current value, and the duration of the sampling current value being equal to the starting current value is not less than the starting timeout value, it is judged that the starting of the smart electronic lock is blocked.

[0013] According to some embodiments, the aforementioned method also includes: if the sampling current value is equal to the rotation process current value, and the duration of the sampling current value being equal to the rotation process current value is less than the rotation timeout value, then it is judged that the smart electronic lock is in a rotation state; if the sampling current value is greater than the rotation process current value, and the duration of the sampling current value being equal to the rotation process current value is not less than the rotation timeout value, then it is judged that the smart electronic lock is blocked from rotating into place.

[0014] According to some embodiments, the aforementioned method further includes: if the sampling current value is equal to the rotation-to-position current value, and the duration of the sampling current value being equal to the rotation-to-position current value reaches the rotation-to-position timeout value, then it is determined that the smart electronic lock has been rotated to the position.

[0015] According to some embodiments, the aforementioned method further includes: when it is determined that the startup of the smart electronic lock is blocked, adjusting and increasing the input power of the DC motor.

[0016] According to some embodiments, the aforementioned method further includes: when it is determined that the smart electronic lock is obstructed from rotating into position, adjusting and increasing the current value of the rotation process.

[0017] According to some embodiments, the aforementioned method further includes: when the smart electronic lock is rotated into place, stopping the rotation of the DC motor.

[0018] According to one aspect of the present application, a smart electronic lock is proposed, comprising: a sampling unit, which obtains a temporal distribution result of a sampled current value of the DC motor; a state judgment unit, which obtains an operating state of the smart electronic lock based on the temporal distribution result of the sampled current value and a preset state current value and state time value; and a lock control unit, which controls the smart electronic lock based on the operating state.

[0019] According to one aspect of the present application, an electronic device is proposed, comprising: one or more processors; a storage device for storing one or more programs; when the one or more programs are executed by the one or more processors, the one or more processors implement any of the methods described above.

[0020] Beneficial effects of this application:

[0021] According to some embodiments, the present application can determine the working status of the electronic lock by simply sampling the current value of the DC motor of the smart electronic lock, thus getting rid of the reliance of the prior art on auxiliary devices.

[0022] According to some embodiments, the present application scheme pre-sets relevant parameters of current value and time value under different working states for the smart electronic lock based on the properties of the DC motor itself, so that the working state of the electronic lock can be judged only by real-time sampling of the current value of the DC motor.

[0030] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art.

For example, some operations / steps may be decomposed, while others may be combined or partially combined. Therefore, the actual execution order may vary depending on the actual situation.

[0033] The terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish between different objects, not to describe a particular order. Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions.

[0034] Smart electronic locks are driven by motors. Controlling them requires information such as the motor's operating status. While stepper motors can easily provide information about their operating status and position, cost considerations often force smart electronic locks to use DC motors. Using DC motors, however, requires auxiliary equipment to obtain information such as the lock's operating status.

[0035] The technical solution proposed in this application can determine the operating status and operating position of the DC motor of the smart electronic lock by sampling only the current value of the DC motor and combining it with preset related current value parameters. Specifically, based on the driving characteristics of the DC motor, this application captures and monitors the driving current value of the DC motor during the driving process, and uses the established judgment logic to infer the operating status of the DC motor. This achieves the goal of solving the misalignment problem caused by the low accuracy of the DC motor's rotation coordinates while meeting the functional requirements of the existing smart electronic lock solution for lock control and reducing hardware cost overhead. The following will illustrate the technical solution of this application with the help of the accompanying drawings and examples.

[0036] Figure 1 A flow chart showing a method for controlling a smart electronic lock according to an embodiment of the present application is shown.

[0037] like Figure 1 As shown, in S101, the temporal distribution result of the sampled current value of the DC motor is obtained.

[0038] According to an embodiment, the sampling current value of the DC motor may be sampled by utilizing the driving circuit of the DC motor.

[0039] According to one embodiment, reference may be made to Figure 2 The circuit diagram of a control method for a smart electronic lock according to an embodiment of the present application is shown in FIG. The main control MCU monitors the current state of the DC motor during driving by using the AD sampling method through the ADC7 pin.

[0040] According to one embodiment, the temporal distribution of the sampled current values ​​of the DC motor is a record of the sampled current values ​​in the time dimension. The sampling result can be represented by a current distribution curve.

[0041] According to one embodiment, in actual applications, the current values ​​sampled in real time at each moment may fluctuate. To facilitate processing, the sampled current values ​​need to be filtered. Specifically, the sampling results of current values ​​fluctuating within the same range are unified, and abnormal, occasional, excessively large or low sampled current values ​​are filtered out to eliminate unnecessary interference and ensure the validity of the sampled data.

[0042] According to one embodiment, the current value of the DC motor can be sampled starting from the moment the smart electronic lock sends a drive signal. The drive signal is an electronic signal sent to the DC motor to start rotating, which can be initiated by the main control MCU of the smart electronic lock.

[0043] In S103, the operating state of the smart electronic lock is obtained based on the temporal distribution result of the sampled current value and the preset state current value and state time value.

[0044] In S105 , the smart electronic lock is controlled based on the operating status.

[0045] According to one embodiment, the smart electronic lock needs to pre-set the current value and time value parameters used as a comparison reference before leaving the factory. The setting process is to run the DC motor normally and record the current value of each operating state and the duration of the corresponding current value.

[0046] According to an example embodiment, the state current value includes a starting current value, a rotation process current value, and a rotation position current value.

[0047] According to an exemplary embodiment, the state time value includes a startup timeout value and a rotation timeout value, wherein the startup timeout value is the maximum threshold value of the duration of the startup state, and the rotation timeout value is the maximum threshold value of the duration of the DC motor maintaining normal rotation.

[0048] According to one embodiment, the temporal distribution of the sampled current value can generally reflect the three operating states of the smart electronic lock. Figure 3 The schematic diagram of the current value sampling results of the embodiment of the present application is shown, wherein the horizontal axis represents time, the vertical axis represents current value, and point O is the origin. As mentioned above, when the drive signal for driving the DC motor is triggered, the sampling current value of the DC motor begins to be recorded. Among them, the I1 record represents the starting current value when the DC motor starts, and its current value is usually higher. It can be seen that after the sampling record starts, the starting current value will continue for a period of time until T1 and then decrease to I2. I2 is the process current value during the stable rotation process of the DC motor. When I2 is maintained until T2, it rises to I3 current value. I3 is the rotation current value of the DC motor after it rotates to the full position and is passively stopped due to the restriction of the limit device. When I3 is maintained until T3, the current value returns to zero, that is, the rotation of the DC motor stops, which means that the DC motor rotates to the full position. The process from O to T1 represents the process from starting to stable rotation of the DC motor, which also reflects the starting timeout value; the process from T1 to T2 represents the process of normal uniform rotation of the DC motor, which also reflects the rotation timeout value; the process from T2 to T3 represents the process of stopping driving the DC motor after the DC motor rotates to the position, which also reflects the rotation to the position timeout value.

[0049] According to an example embodiment, the operating state of the smart electronic lock includes a startup state and a startup blocked state.

[0050] According to one embodiment, if the sampled current value is equal to the startup current value, and the duration of the sampled current value being equal to the startup current value is less than the startup timeout value, the smart electronic lock is determined to be in the startup state. In other words, if the sampling result is consistent with the performance of the preset parameters, it indicates that the smart electronic lock is operating normally in this operating state.

[0051] According to another embodiment, if the sampling current value is equal to the starting current value, and the duration of the sampling current value being equal to the starting current value is not less than the starting timeout value, it is determined that the smart electronic lock is blocked from starting. In other words, the DC motor of the smart electronic lock has experienced too long a time during the starting phase, that is, exceeded the timeout period. Figure 3 The time from O to T1 in the figure indicates that the electronic lock may be stuck and unable to rotate normally, such as rust or foreign objects blocking it.

[0052] According to one embodiment, when it is determined that the smart electronic lock is blocked from starting, the input power of the DC motor can be adjusted and increased to try to rotate the DC motor. If the DC motor still fails to start, an alarm message can be issued to promptly notify the user or maintenance personnel to perform maintenance and inspection.

[0053] According to an example embodiment, the operating state of the smart electronic lock further includes the smart electronic lock being in a rotating state and the smart electronic lock being blocked from rotating into place.

[0054] According to one embodiment, if the sampled current value is equal to the rotational current value, and the duration of this equalization is less than the rotational timeout, the smart electronic lock is determined to be in the rotational state. In other words, if the sampling result is consistent with the pre-set parameters, the smart electronic lock is operating normally in this state.

[0055] According to another embodiment, if the sampled current value is greater than the rotation process current value, and the duration of the sampled current value being equal to the rotation process current value is not less than the rotation timeout value, then it is determined that the smart electronic lock is obstructed from rotating into position. This may be due to the DC motor's reduced rotation speed, resulting in a longer time to complete the specified rotation stroke. This may be because the DC motor encounters greater resistance during rotation than when it leaves the factory. In this case, the aforementioned rotation process current value can be adjusted to increase, that is, the parameter of the rotation process current value can be adjusted to adapt to the current lubrication level of the DC motor's rotating mechanism. It can also prompt an alarm that the DC motor's rotating mechanism requires lubrication measures.

[0056] According to another embodiment, if the sampled current value is equal to the rotation process current value, and the duration of the sampled current value being equal to the rotation process current value is not less than the rotation timeout value, it is determined that the smart electronic lock is blocked from rotating into position. In other words, the DC motor of the smart electronic lock has experienced too long a time in the normal rotation stage, that is, exceeded the Figure 3 The time from T1 to T2 in the figure is the same as the time from T1 to T2 in the figure. This situation may be caused by the rotation part of the DC motor of the electronic lock being disconnected from the limit device, resulting in the DC motor's rotation not being properly hindered after it rotates to the desired position. An alarm message can be issued to promptly notify the user or maintenance personnel to perform maintenance and repairs.

[0057] According to another embodiment, the sampled current value at this stage may be higher than the current value during the rotation process, which may mean that the DC motor encounters greater resistance during rotation than when it leaves the factory, which means that the DC motor's rotating mechanism needs lubrication.

[0058] According to an example embodiment, the operating state of the smart electronic lock further includes the smart electronic lock being rotated into position.

[0059] According to one embodiment, if the sampled current value is equal to the fully rotated current value, and the duration of the sampled current value equaling the fully rotated current value reaches the fully rotated timeout value, the smart electronic lock is determined to have fully rotated. If the sampled current value is equal to the fully rotated current value and the duration of the sampled current value reaches the fully rotated timeout value, it means that the rotation of the DC motor is hindered by the limit device, that is, the lock head has been pushed forward or retracted to the full position. In this case, the DC motor needs to be stopped.

[0060] Figure 4 A block diagram of a smart electronic lock according to an embodiment of the present application is shown.

[0061] like Figure 4 As shown, the intelligent electronic lock includes a sampling unit 401, a state judgment unit 403 and a controlled unit 405, wherein:

[0062] The sampling unit 401 obtains the temporal distribution result of the sampled current value of the DC motor.

[0063] The state judgment unit 403 obtains the operating state of the smart electronic lock based on the temporal distribution result of the sampled current value and the preset state current value and state time value.

[0064] The lock control unit 405 controls the smart electronic lock based on the operating status.
