Detailed Description
The invention provides an electronic lock locking control method, which comprises the following steps:
(1) acquiring a position interval of the auxiliary lock tongue; the operation stage of the current user can be judged by acquiring the position or position interval of the auxiliary bolt;
(2) acquiring a position interval of a main lock tongue; judging the working state of the main bolt;
(3) judging whether the auxiliary bolt moves from the first position interval to the second position interval; and judging whether the main bolt is positioned in the initial position interval of the unlocking state of the door lock, and controlling the motor of the electronic lock to drive the main bolt to move to the locking position interval of the locking direction in a time delay manner after the auxiliary bolt moves to the second position interval.
In the process, because the door is in an open state at the initial stage, the extension amount of the auxiliary bolt is maximum at the moment, and the auxiliary bolt is in a first position interval; when the auxiliary bolt moves from the first position interval to the second position interval, the door closing action of the user can be judged. If the auxiliary bolt is directly selected to be in the second position interval, the main bolt is started, and the auxiliary bolt is also in the second position interval in the state that the door is closed completely, so that the main bolt continues to stretch. Therefore, the electronic lock changes from the first position interval to the second position interval and then controls the main bolt in a delayed mode, and the situation can be avoided.
In the step (3), when the main bolt is detected to be in the middle position interval, if the current of the motor of the electronic lock is greater than the threshold value, the main bolt is controlled to return to the initial position interval. In this case, the current of the electronic lock is increased, which indicates that the motor is blocked, and may indicate that the main bolt of the electronic lock has been extended to the maximum position, i.e., the locked position, or is jammed, for example, the main bolt contacts the doorframe due to misalignment. Therefore, in this case, although the current may be large when the main bolt moves to the maximum position, i.e., the locking position, the electronic lock is already locked, the motor can be directly turned off, and if the electronic lock is locked, the power failure will not be normally locked.
Therefore, when the main bolt is in the middle position interval and is retracted to the initial position interval, the number of times of the retraction of the main bolt is recorded;
judging whether the number of times that the main bolt is withdrawn exceeds a preset value;
if the number of times that the main bolt is withdrawn does not exceed the preset value, the main bolt is driven to move towards the locking position interval in the locking direction again in a delayed mode; this way of attempting to continue locking for a number of cycles can avoid the problems described above.
However, due to an unexpected situation, even if the main bolt still cannot be extended normally after being retracted for multiple times, multiple attempts have been made at this time to indicate that the electronic lock cannot be locked normally, and therefore if the number of times that the main bolt is retracted exceeds a preset value, the electronic lock is controlled to send out an alarm signal; so that the user can even find a problem.
(4) After the main bolt sequentially moves to a locking position interval through an initial position interval and a middle position interval, controlling a motor of the electronic lock to stop driving the main bolt to move continuously;
the first position interval refers to the position where the auxiliary lock tongue naturally extends out to the maximum without being subjected to external force, and the second position interval refers to the position interval when the auxiliary lock tongue is compressed by the door frame or the lock groove and then contracts inwards;
the initial position interval refers to the position when the main lock tongue does not extend outwards, the locking position interval refers to the position when the main lock tongue extends and retracts to the maximum, and the middle position interval refers to the position interval between the initial position interval and the locking position interval.
Based on the control method, the invention provides an electronic lock, which comprises an auxiliary lock tongue, a main lock tongue and a driving mechanism for driving the main lock tongue to reciprocate, wherein the driving mechanism comprises a motor which drives the main lock tongue to move; the method also comprises the following steps:
the first position sensor is used for acquiring a position interval of the auxiliary bolt;
the second position sensor and the third position sensor are used for acquiring a position interval where the main bolt is located;
the auxiliary bolt moves from a first position interval to a second position interval, the main bolt is positioned in an initial position interval of the door lock opening state, and the motor of the electronic lock is controlled to drive the main bolt to move to a locking position interval in the locking direction after the auxiliary bolt moves to the second position interval in a delayed time manner;
and after the main bolt sequentially moves to a locking position interval through the initial position interval and the middle position interval, controlling a motor of the electronic lock to stop driving the main bolt to move continuously.
The electronic lock also comprises a current detection module for detecting the current of the motor of the electronic lock;
when the main bolt is detected to be in the middle position interval, if the current of the motor of the electronic lock is larger than the threshold value, the main bolt is controlled to return to the initial position interval.
The electronic lock also comprises a counting module, a first locking module and a second locking module, wherein the counting module is used for counting the number of times that the main locking tongue is positioned in the middle position interval and is retreated to the initial position interval;
when the main bolt is positioned in the middle position interval and is retreated to the initial position interval, the counting module records the number of times of retreating the main bolt;
judging whether the number of times that the main bolt is withdrawn exceeds a preset value;
if the number of times that the main bolt is withdrawn does not exceed the preset value, the main bolt is driven to move towards the locking position interval in the locking direction again in a delayed mode;
and if the number of times that the main bolt is withdrawn exceeds a preset value, controlling the electronic lock to send out an alarm signal.
