Example 2
s10: fingerprint information input by a user is received.
In this embodiment, a user may enter fingerprint information through, for example, a fingerprint module of the electronic padlock in embodiment 1 of the present invention, and then the main control board of the electronic padlock may receive the fingerprint information entered by the user.
S20: and if the fingerprint information set in the fingerprint database is a non-empty set, matching the fingerprint information with the fingerprint information in the fingerprint information set.
In this embodiment, the fingerprint information registered by the user is already stored in the current default fingerprint database, at this time, the main control board may detect whether the fingerprint information set in the fingerprint database is an empty set, and if the fingerprint information set in the fingerprint database is a non-empty set, the main control board may match the fingerprint information with the fingerprint information set to determine whether the fingerprint information of the current user is the registered fingerprint information.
S30: and if the fingerprint information matched with the fingerprint information exists in the fingerprint information set, controlling the driving motor to unlock according to the running state of the driving motor.
In one embodiment, when it is detected that there is fingerprint information matching the fingerprint information in the fingerprint information set, that is, the fingerprint information of the current user may match with a certain fingerprint information in the fingerprint information set in the fingerprint database, the main control board may control the driving motor to unlock according to the operating state of the driving motor. If it is detected that there is no fingerprint information matching the fingerprint information in the fingerprint information set, that is, the fingerprint information of the current user does not match with a certain piece of fingerprint information in the fingerprint information set in the fingerprint database, an abnormal prompt message may be generated at this time, and the abnormal prompt message may be used to indicate that the matching of the current fingerprint of the user is unsuccessful, and may specifically be prompted by, for example, the acousto-optic prompter in embodiment 1.
In the embodiments of the foregoing steps S10-S30, based on consideration of different operating states of the driving motor in the actual working process, if the driving motor is in an abnormal working state, and the main control board further normally controls the driving motor to rotate, the power consumption of the driving motor is too large, and the driving motor may be damaged; and control driving motor according to driving motor's running state and unblank, not only can save the electric quantity but also can improve driving motor's life.
In one embodiment, the operation state of the driving motor may include, for example, a normal state and a locked state, and specifically, as shown in fig. 4, the driving motor is controlled to unlock according to the operation state of the driving motor, and the following steps S31 to S32 may be performed, including:
s31: and if the running state of the driving motor is a normal state, controlling the driving motor to unlock.
In one embodiment, if the operation state of the driving motor is a normal state, the normal state may be that the motor rotates normally or the working current is normal, and the main control board may control the driving motor to unlock according to the driving motor being in the normal state.
S32: and if the running state of the driving motor is the locked-rotor state, controlling the acousto-optic prompter to send out a first state prompt.
In an application scene, the driving motor may have the problems of locked rotor and the like, if the locked rotor still continues to be controlled to rotate, the driving motor may be over-consumed by the driving motor to the power supply, and the driving motor may be damaged. If the current running state of the driving motor is a locked-rotor state, controlling the power supply to cut off the power supply so as to reduce the power consumption of the power supply and damage the driving motor; meanwhile, the main control board can also control the prompt module to send a first state prompt according to the fact that the driving motor is in the locked-rotor state, and the first state prompt can be used for indicating that the running state of the driving motor is in the locked-rotor state under the current state. In particular, the first status cue may be, for example, a red light and a high frequency buzzer sound to allow the user to notice and check in time. In the embodiments of the above steps S31-S32, the operation state of the driving motor is detected in advance to control whether the driving motor is unlocked, so that not only the problems of consuming a large amount of electric energy and damaging the driving motor due to the blocking of the driving motor can be avoided, but also the electric quantity of the power supply can be avoided from being wasted, the electronic padlock can save more power, and the service life of the electronic padlock can be prolonged.
In one embodiment, if the driving state of the driving motor is the locked-rotor state, the method may further include the following steps S321 to S322:
s321: and detecting the value of the working current of the driving motor in the current state.
In an application scenario, the driving motor may output torque when the rotation speed is 0 rpm, and the torque may be output due to an excessive load of the driving motor, a mechanical failure of the driving motor, or a damage of a bearing, so that the driving motor cannot be normally started to unlock the lock, and the electric quantity of a large power supply is consumed. When the driving motor rotates normally, the rotating magnetic field formed by the stator winding can drag the rotor to rotate, and the magnetic field generated by the induced current in the rotor can induce counter electromotive force (inductive reactance) in the stator winding, so that the effect of increasing the current of the motor stator can be prevented. If the running state of the driving motor is the locked-rotor state, the counter potential (inductive reactance) is gradually reduced or even disappears, the driving motor at the moment is equivalent to an inductive element in a power supply, only the resistance and the inductance of the driving motor exist, and accordingly the working current at the moment is greatly increased. Based on the above analysis, in one embodiment, it is determined whether the operation state of the driving motor is the locked-rotor state by detecting the value of the corresponding working current when the driving motor rotates in the current state.
S322: and if the value of the working current in the preset time is larger than a first preset value, determining that the running state of the driving motor is a locked-rotor state, so that the acousto-optic prompter is controlled to give out a first state prompt.
In one embodiment, the value of the operating current of the driving motor can be detected through the control board, specifically, when the driving motor is started, since the inertia of the rotor changes and needs a certain time, an overshoot phenomenon occurs in the instantaneous operating current of the driving motor from rest to rotation, but the rotor can keep moving at a constant speed afterwards, and then the value of the operating current of the driving motor can tend to a fixed value. If the driving motor is in a locked-rotor state, the value of the working current is gradually increased within a preset time instead of being stable. If the value of the operating current in the predetermined time is greater than the first predetermined value, the first predetermined value may be, for example, 1A or 1.5A, and may be specifically set according to a rated current of the driving motor, or according to a detected corresponding operating current when the driving motor is in a locked-rotor state, and is not limited herein. In this embodiment, when the lock is unlocked, the main control board may detect the working current of the driving motor, and determine whether the value of the working current of the driving motor is greater than a first predetermined value within a predetermined time, and if the value of the working current of the driving motor is greater than the first predetermined value, it may be determined that the operating state of the driving motor is a locked-rotor state, so that the main control board controls the power supply to be powered off, and the control board controls the acousto-optic prompter to send a first state prompt.
In the above embodiment, the operation process of the driving motor in the unlocking state is specifically analyzed through steps S321 to S322, so as to monitor the operation current of the driving motor in a data form, and determine whether the driving motor is in the locked-rotor state. And when monitoring that the driving motor is in the locked-rotor state, the power supply is controlled to be powered off, so that the power consumption of the power supply can be reduced, the occurrence of an accidental state can be avoided, and the safety of the electronic lock can be improved.
In one embodiment, specifically, as shown in fig. 5, before controlling the driving motor to unlock, the method may further include:
s21: and checking the electric quantity of the power supply in the current state, and judging whether the electric quantity of the power supply is greater than a first preset threshold value.

S22: and if the electric quantity of the power supply is greater than a first preset threshold value, controlling the acousto-optic prompter to send out a first electric quantity prompt.
In an embodiment, if the electric quantity of the power supply is greater than a first preset threshold, specifically, if the electric quantity of the power supply in the current state is greater than 20%, the main control board may control the audible and visual indicator to send a first electric quantity prompt, where the first electric quantity prompt may be used to indicate that the electric quantity in the current state is greater than a first preset value, so that the user can be prompted to know the electric quantity of the power supply in the current state, and then control the driving motor to unlock.
S23: and if the electric quantity of the power supply is less than or equal to the first preset threshold value, controlling the acousto-optic prompter to send out a second electric quantity prompt, wherein the second electric quantity prompt can be used for indicating that the electric quantity of the power supply is low.
In an embodiment, if the electric quantity of the power supply in the current state is less than or equal to 20%, the main control board may control the acousto-optic indicator to send a second electric quantity prompt, and the second electric quantity prompt may be used to indicate that the electric quantity of the power supply is low, so that the user knows the power supply circuit in the current state in advance.
Specifically, in an application scenario, the second power prompt may be a prompt sound and/or a light with three long, three short and three long set according to morse code, for example, the three short, three long and three short set, the short sound may be, for example, a short beep of 0.5s, and the long sound may be, for example, a long beep of 0.75s, that is, in this embodiment, the short beep of 0.5 s-the long beep of 0.75 s-the short beep of 0.5s may be used as the sound of the first power prompt. In this embodiment, the user is prompted in advance according to the electric quantity of the power supply before the driving motor is controlled to unlock, so that the user can timely know that the electric quantity in the current state is low and the battery needs to be replaced timely, and the situation that the lock cannot be unlocked due to insufficient electric quantity of the power supply can be avoided.
In the embodiments of the above steps S21-S23, for the unlocking process, whether the driving motor is unlocked or not can be controlled according to the operating state of the driving motor and/or the electric quantity of the power supply, so that not only the driving motor can be protected, but also the electric quantity consumption of the power supply can be reduced, thereby improving the service life of the electronic padlock; in addition, the user can know the electric quantity of the power supply in the current state in time so as to improve the user experience.
In one embodiment, specifically, as shown in fig. 6, the control method may further include:
s40: and determining whether a locking trigger signal generated by a preset operation of a user is received.
