[0026] See also Figure 1 This embodiment provides a door lock control system, including a common motor 100, a control module 200, a current feedback module 300, a drive motor module 400 and a power module 500, wherein the control module 200 is electrically connected to the power module 500 through the drive motor module 400 and the common motor 100 in sequence, and the current feedback module 300 is electrically connected to the common motor 100 and the control module 200, respectively, wherein:

[0027] The current feedback module 300 is used to collect and feedback the working current of the ordinary motor 100 in different time periods during the locking and unlocking process for multiple times;

[0028] The control module 200 trains the working current of the ordinary motor in different time periods during the locking and unlocking processes based on the deep learning network, and establishes a data model of the rotation process of the ordinary motor 100; and controls the drive motor module 400 to drive the ordinary motor 100 to rotate to a preset position according to the data model.

[0029] It should be noted that the door lock control system provided in this embodiment can be applied to smart door lock systems such as fingerprint door locks, password door locks or card swipe door locks. The smart door lock system mainly includes a door lock control system and an execution component. The door lock control system includes a control module 200, a drive motor module 400 and an ordinary motor 100. The execution component includes a lock tongue connected to the stator of the ordinary motor 100. The drive motor module 400 is used to drive the ordinary motor 100 to rotate according to the control signal of the control module 200. The rotation process includes the control of the speed, angle and torque. The lock tongue is used to propel linearly according to the rotation of the ordinary motor 100, thereby completing locking and unlocking.

[0030] Specifically, the door lock control system also includes a current feedback module 300. The current feedback module 300 repeatedly collects the working current of the ordinary motor 100 in different time periods during the locking and unlocking process. The control module 200 continuously self-learns the working current fed back by the ordinary motor 100, continuously adjusts the corresponding control parameters, establishes a data model of the entire rotation process of the ordinary motor 100, and implements precise control of the ordinary motor 100 according to the data model to achieve the effect of a servo motor. At the same time, the door lock control system also solves the problem of inadequate control due to aging of the door lock and torque changes.

[0031] The above-mentioned door lock control system includes a common motor 100, a control module 200, a current feedback module 300, a drive motor module 400 and a power module 500, wherein the control module 200 is electrically connected to the power module 500 through the drive motor module 400 and the common motor 100 in sequence, and the current feedback module 300 is electrically connected to the common motor 100 and the control module 200, respectively, wherein the current feedback module 300 is used to repeatedly collect the working current of the common motor 100 in different time periods during the locking and unlocking process; the control module 200 trains the working current of the common motor in different time periods during the feedback locking and unlocking process based on the deep learning network, and establishes a data model of the rotation process of the common motor 100; and controls the drive motor module 400 to drive the common motor 100 to rotate to a preset position according to the data model. The door lock control system provided by the present invention has low cost and can effectively realize the precise control of the common motor 100.

[0032] In one embodiment, see Figure 2 , the door lock control system also includes:

[0033] A judgment module 600, the judgment module 600 is electrically connected to the current feedback module 300 and the control module 200, respectively, and the judgment module 600 is used to judge whether the working current of the ordinary motor 100 exceeds a preset stall current according to the working current of the ordinary motor 100 in different time periods;

[0034] The control module 200 is used to send a first control signal to the drive motor module 400 to stop driving the ordinary motor 100 to rotate in advance, or send a second control signal to the drive motor module 400 to reduce the output drive current when the operating current of the ordinary motor 100 exceeds the preset stall current.

[0035] In this embodiment, when the rotor of the ordinary motor 100 is stuck in contact with the stator or the lock tongue is stuck, the ordinary motor 100 is likely to be stalled. The motor stalling will generate a large current, resulting in a violent heating effect in the motor stator winding, and in severe cases, the motor will burn out. In order to avoid the adverse effects of motor stalling, the door lock control system provided in this embodiment adds a judgment module 600, which is used to judge whether the working current of the ordinary motor 100 exceeds the preset stalling current according to the working current of the ordinary motor 100 in different time periods. When the working current of the ordinary motor 100 exceeds the preset stalling current, the ordinary motor 100 is stopped in advance or its driving current is reduced to prevent it from burning out.

[0036] In one embodiment, see Figure 3 , the door lock control system also includes:

[0037] A voltage acquisition module 700, the voltage acquisition module 700 is electrically connected to the power module and the control module respectively, and the voltage acquisition module 700 is used to collect the output voltage of the power module during the locking and unlocking process for multiple times;

[0038] The locking position feedback module 800 and the control module 200 are electrically connected to the locking position feedback module 800 and the power module 500, respectively. The locking position feedback module 800 is used to feedback the distance information between the early stop rotation position of the ordinary motor 100 and the preset position during the locking process;

[0039] The control module 200 is used to perform output voltage compensation on the power module 500 and operating current compensation on the ordinary motor 100 according to the distance information and the data model, and drive the ordinary motor 100 to rotate to a preset position.

[0040] In this embodiment, although premature stopping can prevent the ordinary motor 100 from being burned, premature stopping can easily cause the motor to fail to rotate to the preset position and thus fail to lock. The door lock control system provided in this embodiment adds a voltage acquisition module 700 and a locking position feedback module 800, wherein the voltage acquisition module 700 is used to repeatedly collect the output voltage of the power module during the locking and unlocking process; the locking position feedback module 800 is used to feedback the distance information between the position where the ordinary motor 100 stops rotating in advance and the preset position during the locking process; the control module 200 is used to compensate the output voltage of the power module 500 and the working current of the ordinary motor 100 according to the distance information and the established data model, thereby driving the ordinary motor 100 to rotate to the preset position.

[0041] In one embodiment, see Figure 4 , the door lock control system also includes:

[0042] An overcurrent waveform characteristic sampling module 900, which is electrically connected to the current feedback module 300 and the control module 200, respectively, and is used to collect an overcurrent waveform curve when the working current of a common motor exceeds a preset stall current during the unlocking process;

[0043] The control module 200 is used to perform output voltage compensation on the power module 500 and operating current compensation on the ordinary motor 100 according to the overcurrent waveform curve and the data model, and drive the rotation torque of the ordinary motor 100 to be within a preset torque range.

[0044] In this embodiment, although reducing the driving current can prevent the ordinary motor 100 from being burned, reducing the driving current can easily fail to ensure the motor torque. The door lock control system provided in this embodiment adds an overcurrent waveform feature sampling module 900, which is used to collect the overcurrent waveform curve of the ordinary motor's working current exceeding the preset stall current during the unlocking process; the control module 200 is used to compensate the output voltage of the power module 500 and the working current of the ordinary motor 100 according to the overcurrent waveform curve and the data model, thereby driving the ordinary motor 100 so that the torque of the ordinary motor 100 is within the preset torque range.

[0045] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
