The terminal device 100 is installed with an Application (APP) for managing the smart lock 200, and the name and the developer of the application are not limited in the embodiment of the present application.

The embodiment of the present application does not limit the type of the terminal device 100. For example, some examples of terminal devices are: mobile phones, tablet computers, notebook computers, palm computers, wearable devices, and the like.

The embodiment of the present application does not limit the type, shape, structure and specific components included in the smart lock 200. For example, some examples of smart locks are: intelligent door lock, intelligent vehicle lock, intelligent padlock, etc. Optionally, as shown in fig. 1, the smart lock 200 may include, but is not limited to, at least one of the following: a combination dial 201 or a fingerprint touch screen 202. Optionally, the combination disk 201 may be a physical key combination disk, or may be an electronic combination disk.

For convenience of description, in the embodiment of the present application, an example in which an intelligent lock is a door lock and a terminal device is a mobile phone is described.

Optionally, the bluetooth communication in this embodiment of the present application is Bluetooth Low Energy (BLE) communication.

First, an APP installed on a mobile phone to manage a smart lock is exemplified.

The user can add intelligent equipment to the APP. Illustratively, fig. 2 is a schematic diagram of an interface change of adding a smart device to an APP. In this example, the APP may manage multiple types of smart devices, e.g., smart locks, gateways, smart appliances, and so on. Optionally, in other examples, different smart locks correspond to different APPs, for example, smart locks of different manufacturers are matched with corresponding APPs. As shown in fig. 2 (a), a plurality of APP icons are included in the desktop 11 of the mobile phone. The user clicks on the icon 12, opening the smart life application. Accordingly, the mobile phone runs the smart life application in response to the user clicking the icon 12, and displays the main interface 13 of the smart life application, as shown in fig. 2 (b). In the main interface 13 of the smart life application, the lower menu area 14 includes: home, mall, scene and my total 4 menus. Optionally, after the mobile phone runs the smart life application, the system defaults to the currently displayed "home" interface as the main interface 13. At present, the wisdom life is used and is not added any smart machine, and the equipment quantity is 0. The user can click the control 15 in the upper right corner of the main interface 13 to add the intelligent device. Accordingly, the handset displays a window 16 in the main interface 13 in response to the user clicking the control 15, as shown in (c) of fig. 2. The window 16 includes: the number of the added devices, the created scenes, the shared devices and the connected three-party platform is 4. The user clicks the "add device" menu 17 and continues to add smart devices to the APP. Accordingly, the cellular phone displays a prompt window 18 in the main interface 13 in response to the user's operation of clicking the "add device" menu 17, as shown in fig. 2 (d). The user proceeds to the next step by viewing the prompts in prompt window 18. For example, the prompt "smart life" requires bluetooth to be turned on to discover and add bluetooth devices. Is it turned on? ". The user clicks the "open" button 19 in the prompt window 18 and continues to add the smart device to the APP. Accordingly, the cellular phone displays the main interface 20 of the add device in response to the user's operation of clicking the "on" button 19, as shown in fig. 2 (e). The main interface 20 of the adding device comprises a prompt window 21, and the user performs the next operation by looking at the prompt in the prompt window 21. For example, the prompt indicates that the "auto-scan function needs to start the mobile phone location service to be used", and the user clicks the "go start" button 22 in the prompt window 21 to start the mobile phone location service. Accordingly, the mobile phone responds to the operation that the user clicks the 'go to start' button 22, starts the mobile phone location service, and scans whether intelligent equipment exists around the mobile phone based on the Bluetooth. During the scanning process of the mobile phone, the interface change can be shown in (f) in fig. 2, and the main interface 20 of the add-on device includes a prompt message, for example, "scan in progress, please ensure that the smart device is connected to the power supply and is located near the mobile phone". Optionally, the scanning area 24 in the pattern 23 in the main interface 20 may rotate around the center of the circle, so as to present an animation effect and dynamically prompt the user that the mobile phone is currently scanning to find the smart device. Optionally, other ways of adding the smart device are provided in the main interface 20, for example, the user may click the "add manually" button 25 below to add the smart device manually; alternatively, the user may click on the "scan code add" button 26 underneath to add the smart device by scanning its identification code. After the mobile phone scanning is finished, the connectable smart device is displayed, as shown in (g) of fig. 2, the main interface 20 includes the door lock 001 found by the mobile phone scanning, and the user can click the "connect" button 27 to establish the bluetooth connection between the mobile phone and the door lock 001. Correspondingly, the mobile phone responds to the operation that the user clicks the 'connect' button 27, and Bluetooth connection is established between the door lock 001 to complete adding of the intelligent device. Thereafter, as shown in fig. 2 (h), the user may click on the return control 28 in the home interface 20 of the add-on device, displaying the home interface of the smart life application. Accordingly, the mobile phone displays the main interface 13 of the smart life application in response to the user clicking the return control 28, as shown in (i) of fig. 2. At this moment, it is 1 that the smart devices that the wisdom life was used to add have shown in main interface 13, specifically are lock 001.

Optionally, the user may configure the relevant information of the intelligent device in the APP, and the specific content of the relevant information is not limited in the embodiment of the present application. Illustratively, fig. 3 is a schematic diagram of an interface change for adding door lock information to an APP. As shown in fig. 3 (a), the mobile phone currently displays the main interface 31 of my device, and the process that the user operates in the APP to jump to display the main interface 31 is not limited in this example. Suppose that there are 3 smart devices added to APP, including door lock 001, door lock 002 and gateway 1 in the home, and these 3 devices are displayed in the main interface 31. The user can click the door lock 001 and check the related information of the door lock 001. Accordingly, the mobile phone displays the main interface 32 of the door lock 001 in response to the user's operation of clicking the door lock 001, as shown in fig. 3 (b). The main interface 32 of the door lock 001 may include prompt information, for example, "get the mobile phone close to the door lock, click the configuration button after illuminating the password panel", for configuring door lock information, for example, a name of the door lock, and opening and closing of a function related to the door lock. A fingerprint management key 33, a password management key 34, and an unlock record key 35 may also be included. The user can click different keys to perform different operations. For example, the user adds the user's fingerprint information by clicking the fingerprint management key 33, sets a password for the door lock 001 by clicking the password management key 34, or checks the history of unlocking the door lock 001 by clicking the unlocking record key 35.

It should be noted that fig. 2 and 3 are only examples and do not limit the APP and related interfaces for managing the smart lock.

When the user opens the door lock, one implementation way is that the user clicks the unlocking button in the relevant interface of the APP to unlock the door lock. For example, fig. 4 is a schematic diagram of an implementation manner of bluetooth-based unlocking. As shown in fig. 4, when the user wants to unlock the door lock 400, the user clicks the icon 42 in the desktop 41 of the mobile phone 300 to operate the door lock APP. Correspondingly, the mobile phone 300 responds to the operation of clicking the icon 42 by the user, runs the door lock APP, establishes bluetooth connection with the door lock 400, and displays the interface 43. An unlock button 44 is included in the interface 43. The embodiment of the present application does not limit the process of the user operating in the APP to jump to the display interface 43. The user clicks the unlock button 44, and accordingly, the mobile phone 300 sends an unlock instruction to the door lock 400 in response to the user clicking the unlock button 44. The door lock 400 is unlocked according to the unlocking instruction, and the user rotates the door handle to unlock.

It should be noted that, the embodiment of the present application does not limit the interface where the unlocking button is located, and the implementation manners in different APPs are different. Alternatively, in another example, as shown in fig. 3 (a), an unlocking button of each door lock is included in the main interface 31. For example, the unlocking key of the door lock 001 is the key 36, and the user can click the key 36 to unlock the door lock 001.

As can be seen, in the above implementation, unlocking requires user involvement.

The embodiment of the application provides an unlocking method based on Bluetooth, and when terminal equipment is in Bluetooth communication with a door lock, the terminal equipment has two kinds of transmitting power which can be respectively called as normal power and ultra-small power. The value of the ultra-low power is small compared to the normal power, and the signal transmission distance is limited, typically several tens of centimeters. And the terminal equipment adopts ultra-small power to send an unlocking instruction to the door lock, and adopts normal power to send other data to the door lock. For example, fig. 5 is a schematic diagram illustrating a principle of a bluetooth-based unlocking method according to an embodiment of the present application. As shown in fig. 5, the user carries the mobile phone 300 with him, the range in which the mobile phone 300 performs bluetooth communication with normal power is denoted as range 51, the range in which bluetooth communication with ultra-low power is denoted as range 52, and the range 51 is larger than the range 52. When the mobile phone 300 and the door lock 400 are within the range 51, the mobile phone 300 and the door lock 400 can transmit other data. When the distance between the mobile phone 300 and the door lock 400 is small enough to be within the range 52, the door lock 400 can receive the unlocking instruction sent by the mobile phone 300. The mobile phone shortens the transmission distance of the unlocking instruction sent by the mobile phone by setting the ultra-small power, thereby providing a support for carrying out the non-inductive unlocking based on the Bluetooth and improving the safety of the non-inductive unlocking of a user. Therefore, the user does not need to perform unlocking operation in a mobile phone interface, the mobile phone sends an unlocking instruction to the door lock by adopting ultra-low power, correspondingly, the door lock is unlocked safely according to the received unlocking instruction, the noninductive unlocking of the user is realized, the unlocking efficiency is improved, and the user experience is improved.

Next, a concept related to the embodiment of the present application will be explained.

1. Normal power and ultra-low power

The normal power refers to power used by the terminal device in the existing bluetooth communication. The ultra-low power is used for sending an unlocking command to the door lock by adopting low-numerical transmitting power in order to ensure the safety of non-inductive unlocking. The technical principle can be seen in fig. 5.

Optionally, the mobile phone may send other information related to the unlocking instruction to the door lock by using ultra-low power, so that the door lock further verifies whether the received unlocking instruction is correct and complete, and the security of the non-inductive unlocking is further improved. The embodiment of the present application does not limit specific contents of other information.

It should be noted that, in the embodiment of the present application, a value or a value range of the ultra-low power is not limited. It can be understood that the smaller the value of the ultra-low power is, the shorter the transmission distance of the signal is, and the higher the safety of the bluetooth-based non-inductive unlocking is. Optionally, the ultra-small power may be below-50 dBm to-60 dBm, so that the unlocking instruction may be received only when the door lock is within a distance of several tens of centimeters from the terminal device, for example, the distance between the door lock and the terminal device is below 30 centimeters to 50 centimeters.

It should be noted that, in the embodiments of the present application, names of the normal power and the ultra-small power are not limited. Alternatively, the ultra-low power is also referred to as a first transmission power, and the normal power is also referred to as a second transmission power.

2. Non-inductive unlocking function of terminal equipment

The non-inductive unlocking means that when a user needs to open the door lock, the user is not required to participate in unlocking operation. For the user, the unlocking of the door lock is not sensed, and the user experience can be improved. For example, in the scenario shown in fig. 4, the user needs to click the unlock button to unlock the mobile phone, which is not a sensorless unlock.

The noninductive unlocking function of the terminal equipment means that the terminal equipment can adopt ultra-small power to send an unlocking instruction to the intelligent door lock. The name of the non-inductive unlocking function is not limited in the embodiment of the application.

Optionally, in an implementation manner, the terminal device supports the non-inductive unlocking function by default.

Optionally, in another implementation manner, the non-inductive unlocking function of the terminal device may be turned on or off by the user. The setting mode of the user is not limited in the embodiment of the application. For example, the setting may be performed by voice, a preset gesture, or an operation in an associated display interface.

3. Non-inductive unlocking function of door lock

The non-sensory unlocking function of the door lock refers to a function that can be unlocked without the user participating in an unlocking operation.

Optionally, in one implementation, the door lock supports a non-sensory unlock function by default.

Optionally, in another implementation, the lock may be unlocked or closed by the user in the APP that manages the lock. The setting mode of the user is not limited in the embodiment of the application. For example, the setting may be performed by voice, a preset gesture, or an operation in an associated display interface.

Fig. 6 is an interface diagram for setting a non-inductive unlocking function of a mobile phone and a door lock according to an embodiment of the present application. Continuing to fig. 3 (b), the user clicks on control 37, displaying more information about door lock 001. Accordingly, the cellular phone displays the interface 61 in response to the user's operation of clicking the control 37, as shown in (a) of fig. 6. Further information of the door lock 001 is included in the interface 61, such as device name, warranty information, device information, and version upgrade. The interface 61 also comprises a unbinding device button 62, and a user can click the button 62 to unbind the mobile phone from the door lock 001. The interface 61 further includes a switch control 63 for a non-inductive unlocking function, which is used to set the non-inductive unlocking function of the mobile phone and the door lock 001. Alternatively, a different display modality of the switch control 63 may indicate whether the non-sensory unlock function is on or off. Currently, the non-inductive unlocking function of the mobile phone and the door lock 001 is in a closed state. The user can click the switch control 63, and accordingly, the mobile phone responds to the click operation of the user to open the non-inductive unlocking function of the mobile phone and the door lock 001, and the display form of the switch control 63 changes, as shown in fig. 6 (b).

Fig. 6 is an example, and the manner of providing the function of non-inductive unlocking of the cellular phone and the door lock is not limited. Alternatively, the functions of the mobile phone and the door lock for non-inductive unlocking can be set separately, or can be set by one key as shown in fig. 6.

In the following, an application scenario to which the embodiment of the present application is applied will be described by way of example, but the application scenario is not limited.

Optionally, in an example, fig. 7 is a schematic view of an application scenario applicable to the embodiment of the present application, and illustrates a process in which a distance between a user carrying a mobile phone and a door lock gradually decreases before the user enters a door. As shown in fig. 7 (a), when the user a carries the mobile phone a at position 0, the distance between the user a and the door lock is too far, which exceeds the bluetooth communication range of the mobile phone a under normal power, and the mobile phone a cannot perform bluetooth communication with the door lock. As shown in fig. 7 (b), as the user a moves towards the door lock, the distance between the mobile phone a and the door lock is reduced, and when the user a is at position 1, the mobile phone a can perform bluetooth communication with the door lock by using normal power, but cannot perform bluetooth communication with the door lock by using ultra-low power. Where range 52 shows the range where handset a employs ultra-low power for bluetooth communication. At this time, if the mobile phone a adopts ultra-low power to send an unlocking instruction to the door lock, the door lock cannot receive the unlocking instruction, and cannot be unlocked. As shown in fig. 7 (c), as the user a continues to move toward the door lock, the distance between the mobile phone a and the door lock continues to decrease. Fig. 7 (c) is similar to fig. 7 (b), and the mobile phone a cannot perform bluetooth communication with the door lock using ultra-low power. As shown in fig. 7 (d), as the user a continues to move towards the door lock, when the user a is at the position 3, the mobile phone a may perform bluetooth communication with the door lock by using normal power, or may perform bluetooth communication with the door lock by using ultra-low power. At the moment, the mobile phone A sends an unlocking instruction to the door lock by adopting ultra-low power, and the door lock can be unlocked after receiving the unlocking instruction.

Optionally, in another example, fig. 8 is a schematic view of another application scenario in which the embodiment of the present application is applied, and shows a scenario in which a user enters a door from the outside of the door and places a mobile phone near a door lock. Fig. 8 (a) is the same as fig. 7 (d), and the description thereof is omitted. As shown in fig. 8 (b), after the user a enters the door, the mobile phone a is placed near the door lock, the door lock is located in a range 52 where the mobile phone a performs bluetooth communication with the door lock by using ultra-low power, and the mobile phone a may perform bluetooth communication with the door lock by using normal power or ultra-low power. Optionally, as shown in fig. 8 (c), if the mobile phone a determines that the mobile phone a is currently located in the door and does not need to unlock, the ultra-low power is not used to send an unlocking instruction to the door lock, so that power consumption of the mobile phone a is saved, and safety of the non-inductive unlocking is further improved.

Optionally, in another example, fig. 9 is a schematic view of another application scenario applicable to the embodiment of the present application, which shows a scenario in which a relay attack risk exists. As shown in fig. 9, 2 attackers are included, identified as attacker 1 and attacker 2. The distance between the user A and the door lock is far, the mobile phone A can adopt normal power to carry out Bluetooth communication with the door lock, and adopts ultra-low power to carry out Bluetooth communication with the door lock. The attacker 1 carries relay equipment and is positioned near the user A, and is used for intercepting the information sent to the door lock by the mobile phone A and sending the intercepted information to the mobile phone 2 carried by the attacker 2. The attacker 2 carries the mobile phone 2 to be positioned near the door lock, and the mobile phone 2 communicates with the door lock by using the intercepted information, so that danger is caused. In the scene, because the range 52 of the mobile phone a adopting ultra-low power for bluetooth communication is small, for example, tens of centimeters, and the distance between the attacker 1 and the user a is usually not less than tens of centimeters, the relay device cannot intercept the unlocking instruction sent by the mobile phone a, the risk that the relay device intercepts the unlocking instruction is solved, the safety of the door lock is improved, and the relay attack is successfully defended.

The technical solution of the present application will be described in detail by specific examples. The following embodiments may be combined with each other and details of the same or similar concepts or processes may not be repeated in some embodiments.

The terms "first," "second," "third," "fourth," and the like in the embodiments of the present application, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

Fig. 10 is a message interaction diagram of a bluetooth-based unlocking method according to an embodiment of the present application. The execution main body related to the embodiment comprises a mobile phone and a door lock. As shown in fig. 10, the bluetooth-based unlocking method provided in this embodiment may include:

and S1001, the door lock sends BLE broadcast messages.

And S1002, carrying out BLE scanning by the mobile phone.

Specifically, the bluetooth function needs to be unlocked for the mobile phone and the door lock. In this embodiment, the execution sequence of S1001 and S1002 is not limited, the door lock may send BLE broadcast messages for a long time, and the mobile phone may perform BLE background scanning for a long time. If the mobile phone receives BLE broadcast messages sent by the door lock, the BLE broadcast messages comprise the identity information of the door lock, and the door lock can be identified according to the BLE broadcast messages.

The bluetooth broadcast and scan can refer to the bluetooth standard protocol Core v5.2 Vol6 PartD 3/4/5, which is not described in detail in this embodiment.

S1003, the mobile phone generates a target message, and the target message is used for indicating the door lock to unlock.

The target message includes identity information of the mobile phone and identity information of the door lock, and the implementation manner of the identity information is not limited in this embodiment, for example, identification information or an address of the device.

Because a door lock is added before the mobile phone, for example, in the process shown in fig. 2, the mobile phone establishes bluetooth connection with the door lock and performs an initial pairing authentication process, and the mobile phone and the door lock store opposite party information. Through the identity information of the mobile phone and the identity information of the door lock, the target message indicates the door lock to unlock, and correspondingly, the door lock can determine that the target message indicates the door lock to unlock.

Optionally, the target message may include an unlocking instruction, where the unlocking instruction is used to instruct the door lock to unlock.

And S1004, the mobile phone sends the target message to the door lock by adopting ultra-low power.

For the ultra-low power, reference may be made to the above description, which is not described herein again. When the distance between the mobile phone and the door lock is long, the door lock cannot receive the target message. When the distance between the mobile phone and the door lock is short, the target message can be received.

Optionally, the mobile phone may continuously send the target message to the door lock by using the first transmission power until the preset sending duration is reached or the preset sending times is reached. The present embodiment does not limit the value of the preset sending duration or the preset sending times.

The target message is continuously sent for multiple times through the mobile phone, the success rate of receiving the target message by the door lock is improved, and the door lock can be unlocked. By setting the preset sending time length or the preset sending times, the condition that the mobile phone sends the target message all the time is avoided, the energy consumption is saved, and the unlocking safety is improved. For example, in the scenario shown in fig. 8 (a), the user is always outside the door, and the number of times that the mobile phone sends the target message is limited, so that the situation that the door lock receives the target message all the time and is unlocked all the time is avoided, and the safety of the door lock is improved.

Optionally, in an implementation, the target message may be a BLE broadcast message. That is, the cell phone may transmit a BLE broadcast message to the door lock with ultra-low power, where the BLE broadcast message is used to indicate that the door lock is unlocked. Accordingly, the door lock receives the BLE broadcast message through the BLE scanning. In the implementation mode, BLE connection does not need to be established between the mobile phone and the door lock, and message flow is saved.

Optionally, in another implementation, after the mobile phone establishes a BLE connection with the door lock, the mobile phone sends the target message through the BLE connection.

And S1005, unlocking the door lock according to the target message.

For ease of understanding, S1003 to S1005 may be referred to as an unlocking phase.

As can be seen, according to the bluetooth-based unlocking method provided by this embodiment, the mobile phone and the door lock perform BLE broadcasting and scanning according to the existing flow, and perform bluetooth communication. After the mobile phone identifies the door lock, the target message is sent by adopting ultra-low power, and the transmission distance of the target message is limited. When the distance between the mobile phone and the door lock is long, for example, in the scenes shown in (a), (b), and (c) in fig. 7 or in the scene shown in fig. 9, even if the mobile phone sends the target message, the door lock cannot be received, and the door lock cannot be unlocked. When the distance between the mobile phone and the door lock is close, for example, in a scenario shown in (d) in fig. 7 or in a scenario shown in fig. 8, the door lock may receive the target message and may be unlocked according to the target message. The transmission distance of the target message is limited by setting ultra-low power, and the safety of unlocking the door lock is ensured. The door lock executes unlocking according to whether the target message is received or not, so that the user is prevented from participating in unlocking operation, the non-inductive unlocking of the user is realized, and the user experience is improved.

Optionally, the bluetooth-based unlocking method provided in this embodiment may further include:

s1006, the door lock sends a response message to the mobile phone, wherein the response message is used for indicating whether the door lock is successfully unlocked.

Correspondingly, the mobile phone receives a response message sent by the door lock.

If the response message indicates that the door lock is successfully unlocked, the mobile phone can stop sending the target message.

If the response message indicates that the door lock is unlocked unsuccessfully, optionally, the mobile phone can retransmit the target message to the door lock by adopting ultra-low power. Optionally, the number of retransmissions may be set, where the number of retransmissions is the maximum number of times that the mobile phone continuously receives the response message indicating that the door lock is failed to be unlocked, and the number of retransmissions is not limited in this embodiment. Alternatively, the handset may refer to S1004 each time it retransmits the target message. Optionally, the mobile phone may output a prompt message for prompting the user that the door lock is unlocked unsuccessfully, so that the user triggers sending of the target message again, or the user selects another unlocking mode. For example, the manner of clicking the unlock key shown in fig. 4 is adopted. When the mobile phone outputs the prompt message, the prompt message can be output by voice or displayed in a related interface. The present embodiment does not limit the specific content of the prompt information.

if the mobile phone does not receive the response message sent by the door lock, the target message can be retransmitted to the door lock by adopting ultra-low power. See the relevant description in S1006, and will not be described herein.

On the basis of the embodiment shown in fig. 10, fig. 11 is another message interaction diagram of the bluetooth-based unlocking method provided in the embodiment of the present application. The execution main body related to the embodiment comprises a mobile phone and a door lock.

As shown in fig. 11, optionally, before the mobile phone sends the target message to the door lock with ultra-low power in S1004, the method may further include:

s1007, the mobile phone judges whether the positions of the mobile phone and the door lock meet a preset condition.

If the positions of the mobile phone and the door lock meet the preset condition, S1004 is executed. The unlocking stage includes S1003, S1007, and S1004 to S1005.

Specifically, because the distance for sending the target message by the mobile phone with ultra-low power is limited, the target message is sent only when the positions of the mobile phone and the door lock meet the preset condition, and the power consumption of the mobile phone is saved. For example, in the scenario shown in (a), (b), and (c) in fig. 7 or the scenario shown in fig. 9, the mobile phone is far away from the door lock, and does not satisfy the preset condition, and the mobile phone may not send the target message. In the scenario shown in fig. 7 (d) or the scenario shown in fig. 8, the distance between the mobile phone and the door lock is close enough to send the target message. For another example, in the scenario shown in (c) of fig. 8, the user does not need to unlock the door when the user is located inside the door, and the mobile phone may not send the target message, which not only saves the power consumption of the mobile phone, but also improves the security of the door lock.

The information for determining the positions of the mobile phone and the door lock is different, and the corresponding preset conditions can be different. The information determining the position of the cell phone and the door lock may include, but is not limited to, at least one of the following: the position information of the mobile phone, the position information of the door lock, or the signal intensity of the door lock sending signal received by the mobile phone. The location information includes, but is not limited to, at least one of the following: the positioning method includes the steps of obtaining Global Positioning System (GPS) position information, beidou satellite navigation system position information, or combining information fusion positioning position information such as base station information, wiFi signal characteristics, geomagnetism and the like.

Optionally, before the mobile phone generates the target message in S1003, the method may further include:

and S1008, the door lock sends the capability information of the door lock, and the capability information is used for indicating whether the door lock supports the non-inductive unlocking.

Correspondingly, the mobile phone receives the capability information of the door lock.

And S1009, the mobile phone judges whether the door lock supports the non-inductive unlocking according to the capability information of the door lock.

And if the capability information of the door lock indicates that the door lock supports the non-inductive unlocking, S1003 is executed, and the target message is sent to the door lock by adopting ultra-low power, so that the non-inductive unlocking of the user is realized.

If the capability information of the door lock indicates that the door lock does not support the non-inductive unlocking, the step S1003 and the subsequent steps are not executed. Optionally, the mobile phone may output a prompt message for prompting that the door lock does not support the non-inductive unlocking, so that the user selects another unlocking mode. For example, the manner of clicking the unlock key shown in fig. 4 is adopted. When the mobile phone outputs the prompt message, the prompt message can be output by voice or displayed in a related interface. The present embodiment does not limit the specific content of the prompt information.

Optionally, before the step S1008 of sending the capability information of the door lock, the method may further include:

and S1010, the mobile phone sends a capability query request message to the door lock.

Correspondingly, the door lock receives the capability query request message sent by the mobile phone.

For ease of understanding, S1010, S1008 to S1009 may be referred to as a door lock capability identification phase.

Optionally, in an implementation, the capability information of the door lock may be carried in a BLE broadcast message sent by the door lock. Correspondingly, the mobile phone receives the BLE broadcast message through BLE scanning, so that the capability information of the door lock is obtained. In the implementation mode, BLE connection does not need to be established between the mobile phone and the door lock, and the message flow is saved.

Optionally, in another implementation manner, after the door lock establishes BLE connection with the mobile phone, the door lock sends the capability information of the door lock through BLE connection.

Optionally, the door lock may transmit the capability information of the door lock according to a generic attribute profile (GATT) protocol. The GATT organizes the data to be transmitted by an attribute table. Multiple attributes may be included in the GATT attribute table. An attribute contains a handle, a Universally Unique Identifier (UUID), and a value. Handles are indices of attributes in the GATT table, and the handle for each attribute is unique within a device. The UUID contains information of the data type in the attribute table, which is key information to understand the meaning of each byte of the value in the attribute table. Fig. 12 is a schematic diagram of a data format for transmitting the doorlock capability information by using the GATT protocol according to an embodiment of the present application. As shown in fig. 12, the GATT attribute table includes a device service capability attribute (UUID 1) and other service attributes (UUID 2). The device service capability attribute includes a non-inductive unlock characteristic, and a Type (Type) of the non-inductive unlock characteristic includes: sensorless unlocking, ranging broadcasts, geographic location verification, and other capability values. Each Type (Type) is identified by a different Value (Value). For example, the Value of the non-sensory unlock (Value) is tune, indicating that the door lock supports the non-sensory unlock function. Similarly, the door lock also supports a send range broadcast function and a geo-location verification function.

Optionally, after the BLE scanning is performed by the mobile phone in S1002, the unlocking method based on bluetooth provided by this embodiment may further include:

and S1011, establishing BLE connection between the mobile phone and the door lock.

The BLE connection can be referred to a Bluetooth standard protocol Core v5.2 Vol6 PartD 3/4/5, and the embodiment is not described in detail.

On the basis of the embodiment shown in fig. 10 or fig. 11, in another embodiment of the present application, implementations of S1003 and S1005 in the unlocking stage are provided. In this embodiment, before the mobile phone generates the target message in S1003, the method may further include:

And at the mobile phone side, the target message is generated according to the encrypted information, so that the safety of the target message is improved. And at the door lock side, the received target message is subjected to security verification according to the encrypted information, and unlocking is performed only when the verification is passed, so that the security of door lock unlocking is improved.

Optionally, to further improve security, the door lock may update the encrypted information. Optionally, the door lock may update the encrypted information periodically, and the update period is not limited in this embodiment. Optionally, the mobile phone and the door lock may trigger the door lock to update the encryption information after BLE connection is established each time.

That is, the door lock sends a BLE broadcast message that includes the encryption information. Correspondingly, the mobile phone receives the BLE broadcast message through BLE scanning to obtain the encryption information. The present embodiment does not limit other contents in the BLE broadcast message. Optionally, the BLE broadcast message may further include capability information of the door lock.

In the implementation mode, BLE connection does not need to be established between the mobile phone and the door lock, and message flow is saved.

Optionally, in another implementation, after the door lock establishes the BLE connection with the mobile phone, the door lock sends the encrypted information to the mobile phone through the BLE connection.

Optionally, in an implementation manner, fig. 13 is a further message interaction diagram of the bluetooth-based unlocking method provided in the embodiment of the present application. The security of the target message is verified through the random number and a preset encryption and decryption algorithm, so that the security of the target message and the security of door lock unlocking are improved. The door lock can acquire the random number, and the embodiment does not limit the manner of acquiring the random number and the value range of the random number by the door lock. The encryption information includes a random number. As shown in fig. 13, the unlocking phase may include:

And S1407, unlocking the door lock according to the unlocking instruction.

On the basis of the above embodiment, in another embodiment of the present application, an implementation manner of S1007 in the unlocking stage is provided. In this embodiment, in S1007, the step of determining, by the mobile phone, whether the positions of the mobile phone and the door lock satisfy the preset condition may include:

the door lock sends a ranging broadcast message. Correspondingly, the mobile phone receives the ranging broadcast message sent by the door lock.

The mobile phone judges whether the signal intensity of the ranging broadcast message meets a preset condition.

Generally, the farther the distance between the mobile phone and the door lock is, the lower the signal strength of the ranging broadcast message received by the mobile phone is. Conversely, the closer the mobile phone is to the door lock, the greater the signal strength of the ranging broadcast message received by the mobile phone. Therefore, the signal intensity of the ranging broadcast message received by the mobile phone can reflect the distance between the mobile phone and the door lock, and the mobile phone determines whether to send the target message according to whether the signal intensity of the ranging broadcast message meets the preset condition, so that the power consumption of the mobile phone is saved.

A third scenario: the door lock comprises at least one antenna, and after the door lock is installed on the door, part of the antenna is located on the outer side of the door, and part of the antenna is located on the inner side of the door. For convenience of description, an antenna is provided inside and outside the door as an example. The antenna located outside the door is referred to as a first antenna, and the antenna located inside the door is referred to as a second antenna.

Optionally, in an implementation manner, the method is applicable to a first scene, a second scene, and a third scene.

The door lock transmits a ranging broadcast message, which may include:

the door lock transmits a ranging broadcast message through at least one of all antennas.

The mobile phone determining whether the signal strength of the ranging broadcast message satisfies a preset condition may include:

and judging whether the signal intensity of any ranging broadcast message received by the mobile phone is greater than a preset threshold value.

If the mobile phone determines that the signal strength of the ranging broadcast message is greater than the preset threshold value, which indicates that the distance between the mobile phone and the door lock is short, S1004 may be executed, and the mobile phone sends the target message to the door lock with ultra-low power. If the mobile phone determines that the signal strength of the ranging broadcast message is smaller than the preset threshold value, which indicates that the distance between the mobile phone and the door lock is relatively long, S1004 and the subsequent steps are not executed. When the signal strength of the ranging broadcast message is equal to the preset threshold, S1004 may be executed, or S1004 may not be executed.

In this embodiment, the value of the preset threshold is not limited.

Optionally, in order to improve the accuracy of the determination, if the mobile phone receives the ranging broadcast messages sent by the multiple antennas, whether to send the target message may be determined according to whether the signal strength of the multiple ranging broadcast messages is greater than a preset threshold. For example, when the number of the ranging broadcast messages with the signal strength greater than the preset threshold is greater than a certain number, the mobile phone sends the target message to the door lock by using ultra-low power. Or, as long as the ranging broadcast message with the signal strength larger than the preset threshold exists, the mobile phone sends the target message to the door lock by adopting ultra-low power.

Optionally, in another implementation, the method is applied to the third scenario.

The door lock transmits a ranging broadcast message, which may include:

the door lock transmits a first ranging broadcast message through the first antenna using the target power, and transmits a second ranging broadcast message through the second antenna using the target power. Wherein the first ranging broadcast message includes first identification information indicating that the first antenna is located outdoors. The second ranging broadcast message includes second identification information indicating that the second antenna is located inside the door.

The mobile phone determines whether the signal strength of the ranging broadcast message satisfies a preset condition, which may include:

the mobile phone judges whether the signal intensity of the first ranging broadcast message is greater than the signal intensity of the second ranging broadcast message.

The value of the target power is not limited in this embodiment.

If the signal strength of the first ranging broadcast message is greater than the signal strength of the second ranging broadcast message, indicating that the mobile phone is located outside the door, S1004 may be performed, and the mobile phone transmits the target message to the door lock with ultra-low power. If the signal strength of the first ranging broadcast message is less than the signal strength of the second ranging broadcast message, which indicates that the mobile phone is located indoors, S1004 and the subsequent steps are not executed. When the signal strength of the first ranging broadcast message is equal to the signal strength of the second ranging broadcast message, S1004 may be executed, or S1004 may not be executed.

The following description is made with reference to fig. 15. The mobile phone a is located outside the door, the signal strength of the first ranging broadcast message is marked as RSSI11, and the signal strength of the second ranging broadcast message is marked as RSSI21. The door lock transmits the ranging broadcast message through the first antenna and the second antenna with the same power, due to the blocking of the door, RSSI11> RSSI21. Similarly, handset B is located within the door, and the signal strength of the first ranging broadcast message is labeled RSSI12< the signal strength of the second ranging broadcast message is labeled RSSI22.

Optionally, for the third scenario, the above two ways may be combined. When the distance between the mobile phone and the door lock is determined to be close enough and the mobile phone is located outside the door, the mobile phone sends a target message to the door lock by adopting ultra-low power, and therefore non-inductive unlocking is achieved.

On the basis of the foregoing embodiment, in another embodiment of the present application, in the unlocking stage, before the unlocking the door lock according to the target message in S1005, the method may further include:

the door lock judges whether the positions of the mobile phone and the door lock meet preset conditions or not.

And if the door lock determines that the positions of the mobile phone and the door lock meet the preset condition, executing S1005, and unlocking according to the target message. And if the door lock determines that the positions of the mobile phone and the door lock do not meet the preset conditions, not executing the step S1005 and the subsequent steps. By further judging at the door lock side, the safety of unlocking the door lock is improved.

The information for determining the positions of the mobile phone and the door lock is different, and the corresponding preset conditions can be different. To facilitate distinction from S1007, the preset condition in S1007 may be referred to as a first preset condition, and the preset condition in this embodiment may be referred to as a second preset condition.

Optionally, in an implementation manner, the determining, by the door lock, whether the positions of the mobile phone and the door lock meet a preset condition may include:

the mobile phone obtains an asymmetric key pair. Wherein the asymmetric key pair comprises a public key and a private key.

And the mobile phone sends the public key in the asymmetric key pair to the door lock.

The mobile phone acquires the current position information, encrypts the current position information by using a private key in the asymmetric key pair, and generates encrypted position information.

And the mobile phone sends the encrypted position information to the door lock. Accordingly, the door lock receives the encrypted position information.

The door lock decrypts the encrypted position information according to the public key in the asymmetric key pair to obtain decrypted position information.

The door lock compares the decryption position information with the locally stored initial position information of the mobile phone, and determines whether the error between the decryption position information and the initial position information of the mobile phone is within a preset error range. The initial position information of the mobile phone is the position information of the mobile phone when the BLE connection is established between the mobile phone and the door lock for the first time.

Generally, when the mobile phone first configures the door lock, the geographical location of the mobile phone is written into the door lock. For example, in the process of adding the door lock 001 shown in fig. 2, after the bluetooth connection is established between the mobile phone and the door lock 001, the position information of the mobile phone is sent to the door lock, that is, the initial position information of the mobile phone. Subsequently, before the mobile phone approaches the door lock to perform the non-inductive unlocking, the door lock compares the current position of the mobile phone with the initial position of the mobile phone stored locally, and if the error is larger than a preset error range, the unlocking is refused; if the error is smaller than the preset error range, unlocking is allowed, and the safety of the door lock in noninductive unlocking is further improved.

It should be noted that, the value of the preset error range is not limited in this embodiment. For example 50 meters.
