Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment of the invention provides an unlocking method, which is applied to a door lock and can comprise the following steps of:

and S11, establishing a wireless connection with the electronic equipment.

The electronic equipment comprises a body of the electronic equipment and a SIM card built in the electronic equipment, or only comprises the body of the electronic equipment.

Preferably, the electronic device can be a mobile phone, a tablet and the like which can be provided with a built-in SIM card. Namely, the embodiment of the invention only needs to use the conventional electronic equipment of the user, and does not need to additionally purchase equipment specially used for unlocking. The main body of the electronic device is a part other than the built-in SIM card, and the main body of the electronic device can perform functions such as data processing and data communication.

The wireless connection may include, but is not limited to, a bluetooth, near field communication, NFC, connection. When the electronic equipment approaches the door lock, the door lock can establish wireless connection with the electronic equipment.

And S12, performing connection authentication on the electronic equipment, and if the electronic equipment passes the connection authentication, taking the electronic equipment as target electronic equipment and keeping wireless connection with the target electronic equipment.

Specifically, after the electronic equipment is wirelessly connected with the door lock, the door lock performs connection authentication operation on the electronic equipment, and the connection authentication operation only needs to be performed by adopting conventional wireless connection authentication operation, for example, if the smart door lock sends an authentication request to a mobile phone end, the mobile phone end is required to perform authentication operation; cell-phone end and intelligent lock authentication success then both establish the bluetooth and continue to connect, otherwise the bluetooth connection interrupt, send the relevant instruction information of lock cell-phone software APP in the cell-phone before the interrupt, require APP to pop out the prompt dialog box: "bluetooth authentication fails and equipment needs to be replaced".

And if the body of the target electronic equipment is wirelessly connected with the door lock, a first wireless communication channel is established, and if the SIM card is wirelessly connected with the door lock, a second wireless communication channel is established.

In this embodiment, connect the authentication to electronic equipment, can guarantee that only the user of the permission of unblanking can unblank. For example, two door locks in close proximity, one of which is the target door lock (own door lock) and the other of which is the non-target door lock (neighboring home door lock). However, when the electronic device is connected, the authentication of the electronic device to the non-target door lock fails, that is, only the home door lock can be successfully authenticated, and it is ensured that the user can only open the home door lock.

And S13, acquiring the wireless signal strength data between the door lock and the target electronic equipment.

Specifically, for example, bluetooth wireless connection, the built-in bluetooth module that has in the lock, bluetooth module can use RSSI technique to measure the bluetooth signal strength between lock and the target electronic equipment.

The rssi (received Signal Strength indication) is a positioning technique that measures the distance between a Signal point and a receiving point according to the Strength of the received Signal and then performs positioning calculation according to corresponding data.

For example, when a user holds a mobile phone (bluetooth is opened) and approaches to the smart door lock, the bluetooth low energy BLE bluetooth module in the smart door lock is always in a broadcast state, and along with the approach of the smart phone, the bluetooth signal intensity between the mobile phone and the BLE bluetooth module continuously changes, and the BLE bluetooth module acquires the continuously changing bluetooth signal intensity.

S14, judging whether the user holding the target electronic equipment has door opening intention; if yes, go to step S15; if not, the process is ended.

Specifically, still taking bluetooth wireless connection as an example, based on the bluetooth signal intensity data, it is determined whether a user holding the target electronic device has an intention to open a door, and the target electronic device is connected to the door lock through bluetooth.

Specifically, the BLE Bluetooth module in the intelligent door lock measures and calculates the Bluetooth signal intensity according to the received Bluetooth signal intensity data and by combining a corresponding algorithm, determines the distance change between the BLE Bluetooth module and the Bluetooth module according to the change of the Bluetooth signal intensity, and determines whether the user is close to the door lock or far away from the door lock by combining the current door lock state, thereby determining whether the user has the door opening intention.

Optionally, on the basis of this embodiment, referring to fig. 2, step S12 may include:

and S21, determining distance change data between the door lock and the target electronic equipment based on the wireless signal strength data.

Specifically, taking the bluetooth wireless connection as an example, if the bluetooth signal becomes strong, it indicates that the distance between the door lock and the target electronic device becomes short; if the Bluetooth signal is weakened, the distance between the door lock and the target electronic equipment is increased.

And S22, if the distance change data shows that the distance between the door lock and the target electronic equipment is a trend of continuously decreasing, determining that the user holding the target electronic equipment has door opening intention.

And S23, if the distance change data shows that the distance between the door lock and the target electronic equipment does not trend to be reduced continuously, determining that the user holding the target electronic equipment does not have door opening intention.

If the distance between the target electronic equipment and the door lock is continuously shortened and the current door lock state is the locking state, the situation that the user approaches the door lock and the door is opened is shown. If the distance between the target electronic equipment and the door lock becomes longer or is close, it indicates that the user does not intend to open the door. Or if the current door lock state is the open state, subsequent operation is not needed.

It should be noted that, in order to avoid the user to trigger the unlocking inside the door, the bluetooth signal of the shield door lock inside the room can be mechanically designed.

In addition, the step of accurately judging whether the door opening intention exists or not according to the wireless signal intensity data needs to be combined with a corresponding algorithm in practical application.

And S15, acquiring unlocking data from the target electronic equipment, and executing unlocking operation based on the unlocking data.

It should be noted that steps S11 and S12 are performed as a connection operation, steps S13, S14 and S15 are performed as an intention determination operation, and the connection operation and the intention determination operation are not performed sequentially, may be performed sequentially, or may be performed simultaneously.

Through the embodiment of the invention, in the process that the user holds the electronic equipment to approach the door lock, the door lock can automatically realize wireless authentication connection with the target electronic equipment and give out prompt authentication information; and the door lock can receive the unlocking data sent by the target electronic equipment through the wireless channel, the unlocking data does not need to be input at the lock end of the intelligent door, the problems of leakage and easy stealing caused by inputting the unlocking data at the lock end can be prevented, and in addition, the safety of the unlocking data is further improved by processing the user unlocking data by the SIM card.

In addition, the strength of the signal can be converted into the distance measurement and calculation by collecting the wireless signal strength data between the door lock and the target electronic equipment, and then whether the user has the intention of opening the door or not can be presumed.

And thirdly, the inside of the door lock and the electronic equipment automatically carries out authorization and authentication, the continuous Bluetooth connection can be established only when the authentication is passed, the Bluetooth connection is automatically disconnected when the authentication is not passed, and a corresponding error prompt is popped up through mobile phone software.

Fourthly, through the embodiment of the invention, the mobile phone which is carried about can be used for realizing quick unlocking without carrying a card or a key separately.

The preset key is an unlocking key which is stored in advance and corresponds to the unlocking information.

And S34, comparing the decrypted unlocking information with preset unlocking information, and if the decrypted unlocking information is consistent with the preset unlocking information, executing unlocking operation.

Specifically, taking the fingerprint as an example, the smart door lock end receives the unlocking information that the encryption operation is performed. The unlocking information is decrypted by using the prestored public key corresponding to the individual private key, the public key is compared with the prestored fingerprint corresponding part, unlocking is executed if the public key is compared with the prestored fingerprint corresponding part, and the unlocking success is fed back to the mobile phone APP through the wireless communication channel. Otherwise, the unlocking is failed, if the unlocking is failed, the door lock needs to be fed back to the mobile phone APP through the wireless communication channel, and the user is prompted to perform authentication again.

2. If the electronic device includes the body of the electronic device and the SIM card embedded in the electronic device, referring to fig. 4, step S15 may include:
