In the prior art, an electronic lock generally adopts a detection switch to detect the position of a locking mechanism of the electronic lock to determine the unlocking state of the lock, but the lock state detected by the detection switch cannot accurately correspond to the actual state of the lock due to product dimension errors and/or installation reasons. Especially for the electronic lock adopting the wireless power supply mode, after power supply and communication are interrupted in the unlocking process, the power supply interruption causes that the electronic lock does not complete all unlocking operations, and the communication interruption causes that the unlocking key does not receive the actual state of the electronic lock. When the unlocking and locking operation is carried out again, the unlocking and locking of the electronic lock cannot be accurately controlled by the unlocking and locking key.

Particularly, when the existing electronic lock is unlocked by adopting a driving mechanism such as a motor and the like, the resistance of an external part is usually required to be overcome, so that the power consumption of the driving mechanism is high, the long-time high-power electric quantity output is difficult to ensure by adopting a wireless power supply mode, and the condition of unlocking failure caused by insufficient power supply of the driving mechanism can occur.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings. Those skilled in the art will appreciate that the present invention is not limited to the drawings and the following examples.

The embodiment of the invention provides a control method of an electronic lock, which uses an electronic key as unlocking equipment to unlock the electronic lock, and comprises the following steps as shown in fig. 1 and 2:

step S10: the electronic lockset receives power from the electronic key in response to the electronic key being proximate to the electronic lockset.

In a preferred embodiment of the present invention, the electronic lock is a passive lock, and the working electric energy of the electronic lock is obtained from the power supply of the electronic key. The electronic key can be inserted into the electronic lock, so that a power supply of the electronic key is in wired connection with the electronic lock to supply power to the electronic lock; the electronic key can be inserted into the electronic lock or close to the electronic lock, and the electronic lock is wirelessly powered by the induction coil.

Step S20: the electronic lock receives the authentication of the electronic key and sends the identity information of the electronic lock to the electronic key.

In a preferred embodiment of the present invention, in order to confirm that the electronic key and the electronic lock enter a normal communication state, the electronic key transmits an authentication command to the electronic lock, and the electronic lock receives the authentication command from the electronic key and transmits a response message to the electronic key.

Preferably, in order to ensure communication security between the electronic key and the electronic lock, an encryption communication mode is adopted between the electronic key and the electronic lock, that is, the electronic key sends an authentication command encrypted by applying an initial key to the electronic lock, the electronic lock receives the authentication command encrypted by applying the initial key from the electronic key and generates an update key, and the electronic lock sends response information encrypted by applying an initial synchronization key and the generated update key to the electronic key. And the updated key is used for communication with the electronic key after the electronic lock is successfully authenticated. It should be noted that, in each operation, the initial key is a key used by the electronic key and the electronic lock in the authentication process, and once the authentication is successful, the electronic key and the electronic lock perform subsequent communication using an updated key generated by the electronic lock, so that the security is enhanced.

After the electronic lock is successfully authenticated, the electronic lock sends the identity information of the electronic lock to the electronic key; the electronic lock can also send the identity information to the electronic key while sending the response information to the electronic key. Preferably, the electronic lock sends the unlocking state information to the electronic key while the electronic lock sends the identity information to the electronic key.

Step S30: after the authentication is passed, the electronic lock receives an unlocking or locking command sent by an electronic key in response to determining that the electronic lock belongs to an electronic lock which can be operated based on identity information of the electronic lock.

After the electronic lock is successfully authenticated, the electronic key judges whether the received identity information of the electronic lock exists in an ID list of the electronic lock with the operation authority stored in the electronic key so as to determine whether the electronic lock has the operation authority.

And if the electronic key determines that the electronic key has the operation authority on the electronic lock, an unlocking or locking command is sent to the electronic lock according to an operation instruction sequence of the electronic lock stored in the electronic key.

The electronic lock receives an unlocking or locking command sent by the unlocking device.

When the electronic key receives the unlocking state information of the electronic lock, the electronic key displays the unlocking state information of the electronic lock when the electronic key determines that the electronic key has the operation right on the electronic lock, and the electronic key sends an unlocking or locking command to the electronic lock according to the stored operation instruction sequence of the electronic lock and the unlocking state information of the electronic lock.

For example, when the electronic lock with the operation authority is unlocked by the electronic key, when the electronic lock is in a locked state, the electronic key sends an unlocking command to the electronic lock; when the electronic lock is in an unlocking state, the electronic key does not send an unlocking command to the electronic lock any more, and only the state information of the electronic lock is updated to be in the unlocking state in the electronic key; when the unlocking state fed back from the electronic lock to the electronic key is ambiguous, that is, the electronic lock is in an intermediate state, for example, in one case, the electronic lock feeds back that the unlocked state and the unlocked state exist simultaneously, the electronic key sends an unlocking command to the electronic lock. Under the condition that the electronic lock with the operation authority is locked by the electronic key, when the electronic lock is in an unlocking state, the electronic key sends a locking command to the electronic lock; when the electronic lock is in a locking state, the electronic key does not send a locking command to the electronic lock any more, and only the state information of the electronic lock is updated to be in the locking state in the electronic key; when the unlocking state fed back to the electronic lock by the electronic lock is not clear, namely the electronic lock is in an intermediate state, the electronic key sends a locking command to the electronic lock.

And if the electronic lock is not successfully authenticated or the electronic key does not have the operation authority on the electronic lock, the electronic key prompts abnormity and terminates the operation.

Step S40: the electronic lock responds to the situation that the lock hook moves to a resistance removing position along the direction opposite to the unlocking direction of the lock hook, and drives an unlocking mechanism to unlock or lock the electronic lock, wherein when the lock hook is at the locking position, the lock hook exerts resistance on the unlocking mechanism of the electronic lock; when the lock hook is in the resistance removing position, the lock hook does not apply resistance to an unlocking mechanism of the electronic lock.

For the electronic lock of the embodiment of the present invention, the latch hook may apply resistance to an unlocking mechanism of the electronic lock in the locked position, and the unlocking direction of the latch hook is a direction in which at least one end of the latch hook is separated from the lock body, taking upward as an example. In step S40, by pressing the lock hook downward to the resistance removing position, the unlocking mechanism unlocks or locks the electronic lock after the lock hook no longer applies resistance to the unlocking mechanism of the electronic lock, and compared with the prior art in which the unlocking mechanism is directly unlocked without contact with resistance, the action force of the lock hook on the unlocking mechanism is removed, so that the resistance which needs to be overcome when the motor/unlocking mechanism rotates to unlock is reduced, the power consumption of the electronic lock is reduced, and the wear of components is reduced.

Specifically, when the electronic lock moves from the locking position or the unlocking position to the resistance removing position in response to the lock hook, the unlocking mechanism, such as a motor, is driven to unlock or lock the electronic lock, and the electronic lock detects whether the electronic lock reaches a corresponding unlocking state in real time. After the electronic lock reaches the corresponding unlocking state, the electronic lock is unlocked or locked, and the electronic lock stops driving the unlocking mechanism to work; if it is not detected at a predetermined time that the electronic lock has reached the corresponding unlocking state, this means that there is a malfunction in the electronic lock, for example, the drive or transmission part is jammed, and the electronic lock stops driving the unlocking mechanism in order to protect the electronic lock. And the electronic lock sends the unlocking state information to the electronic key. The electronic key gives out a corresponding operation result according to the received unlocking state information of the electronic lock, if the unlocking state is received when the electronic key carries out unlocking operation, the unlocking is successful, if the locking state is received when the electronic key carries out locking operation, the locking is successful, and if the locking is received when the electronic key carries out locking operation, the operation is failed. Therefore, the electronic key can truly record the actual unlocking state of the electronic lock, the unlocking state of the electronic lock is displayed to an operator in real time through the electronic key, and the operator can be guided to completely unlock (unlock in place) the electronic lock in the operation process of the electronic lock.
