Description

A method for controlling the unlocking of an electronic lock

technical field

The invention belongs to the technical field of electronic locks, and relates to an electronic lock unlocking control method.

Background technique

In the field of electronic locks now, there are already dual-function unlocking methods of electronic unlocking and mechanical unlocking. Because the electronic device of the electronic lock is easily damaged, when the electronic unlocking cannot be performed, the mechanical unlocking is adopted, or the mechanical unlocking can also be adopted when the password is forgotten.

Compared with mechanical locks, electronic locks have the advantage of high safety performance. If the dual functions of electronic unlocking and mechanical unlocking are adopted, the safety advantages of electronic locks will be lost. In view of this situation, the electronic locks of the prior art still have room for further improvement.

Contents of the invention

The invention proposes an electronic lock unlocking control method aiming at the problems existing in the prior art, and aims at increasing the safety performance of a mechanical lock cylinder in the electronic lock and improving the safety of the electronic lock.

The present invention is achieved like this:

An electronic lock unlocking control method, characterized in that the electronic lock includes a mechanical lock core, the mechanical lock core includes a lock body, a lock cover that is sleeved on the lock body and can rotate relative to the lock body, the There is a lock hole on the mechanical lock core, and the lock hole includes a first hole on the lock body and a second hole on the lock cover, the inner end surface of the lock cover is fixedly connected with a gear, and the The gear is meshed with a transmission wheel, the transmission wheel is fixed on a motor, and the motor is electrically connected to the control chip; the unlocking method of the electronic lock includes the following steps:

A. The first hole and the second hole are in a misaligned state. Enter the password, and the control chip will judge whether the password is correct. If the password is correct, enter step B, and if the password is wrong, it will end;

B. The control chip controls the electronic lock cylinder to perform the action of opening the electronic lock;

C. The control chip judges whether the electronic lock has been opened. If the electronic lock has been opened, it will end. If the electronic lock is not opened, the motor will be controlled to rotate until the first hole and the second hole are matched;

D. Insert the key to open the electronic lock through the mechanical lock cylinder;

E. 30-120 seconds after entering the password, the control chip controls the motor to rotate to make the first hole and the second hole misaligned.

In the electronic lock unlocking control method provided by the present invention, since the lock cover of the mechanical lock cylinder can rotate relative to the lock body, the first hole and the second hole are staggered, so that the lock hole is incomplete, making it impossible to perform mechanical unlocking, ensuring The safety performance of the mechanical lock cylinder in the electronic lock is improved, and the overall safety performance of the electronic lock is improved.

detailed description

In the following, the specific implementation manners of the present invention will be further described in detail in conjunction with the accompanying drawings of the embodiments, so as to make the technical solution of the present invention easier to understand and grasp. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

This embodiment provides an electronic lock and a mechanical lock cylinder in the electronic lock. As shown in FIG. 1 , it includes a lock body 100 and a lock cover 200. Rotate relative to the lock body 100. Referring to Fig. 2, there is a lock hole 300 for a key to be inserted on the mechanical lock cylinder, the lock hole 300 includes a first hole 310 on the lock body 100 and a second hole 320 on the lock cover 200, when the lock cover 200 is opposite to the lock body When the 100 is rotated, the first hole 310 and the second hole 320 can be staggered (see FIG. 3 ) and paired (see FIG. 2 ). When the first hole 310 and the second hole 320 are staggered, the electronic lock is in a locked state, and the key cannot be unlocked at this time, which ensures the safety of the mechanical lock cylinder.

Specifically, referring to Fig. 1, the inner end surface of the lock cover 200 is fixedly connected with a gear 210, (not shown in the following structure diagrams), the gear 210 meshes with a transmission wheel, and the transmission wheel is fixed on a motor, and the motor It is electrically connected with the control chip. When the electronic lock is in the locked state and the user enters the password, the electronic lock cylinder will directly control the electronic lock to realize unlocking. At the same time, the control chip controls the rotation of the motor, which drives the gear 210 to rotate to realize the combination of the first hole 310 and the second hole 320. In this way, when the electronic lock cylinder is damaged and cannot directly realize unlocking, the mechanical lock cylinder can also be used to realize unlocking, which not only ensures the safety of the electronic lock, but also ensures the dual functions of electronic unlocking and mechanical unlocking.

Based on the above electronic lock structure, this embodiment provides an electronic lock unlocking control method, the specific steps are as follows:

A. The first hole and the second hole are in a misaligned state. Enter the password, and the control chip will judge whether the password is correct. If the password is correct, enter step B, and if the password is wrong, it will end.

The password in step A can be digital password, fingerprint password, IC card password, etc.

B. The control chip controls the electronic lock cylinder to perform the action of opening the electronic lock.

C. The control chip judges whether the electronic lock has been opened. If the electronic lock has been opened, it ends. If the electronic lock is not opened, the motor is controlled to rotate until the first hole and the second hole are matched.

When the control chip controls the electronic lock cylinder to perform the action of opening the electronic lock, the motor can also be controlled to rotate to make the first hole and the second hole pair up, which can be done by changing the corresponding control program in the control chip.

D. Insert the key to open the electronic lock through the mechanical lock cylinder.

When the electronic lock cannot be unlocked through the electronic lock cylinder, the electronic lock cylinder may have been damaged. At this time, the spare key can be used to unlock the mechanical lock cylinder.

E. 30-120 seconds after entering the password, the control chip controls the motor to rotate to make the first hole and the second hole misaligned.

Ordinary people can complete the unlocking process by key operation in no more than 30 seconds. Under normal circumstances, it is enough to control the motor to rotate in 20 seconds or 30 seconds after entering the password. When there are elderly people in the family who move slowly, the time can also be set to 60 seconds or more. In addition, the control chip can also control the rotation of the motor 5-10 seconds after the lock is unlocked, that is, it can infer that the rotation of the motor is controlled after the key is pulled out. Since the user does not want to unlock the lock after inputting the password, the way of timing since inputting the password can ensure the rotation of the motor and ensure the safety of the electronic lock.

It should be understood that the above descriptions are only preferred embodiments of the present invention, and are not sufficient to limit the technical solutions of the present invention. For those of ordinary skill in the art, within the spirit and principles of the present invention, they can Additions, substitutions, transformations or improvements are described, and all technical solutions after such additions, substitutions, transformations or improvements shall belong to the protection scope of the appended claims of the present invention.
