Description

Technical Field

[0001] The present invention relates to the technical field of smart locks, and in particular to an unlocking method, device, computer equipment and storage medium for a smart door lock. Background Art

[0002] With the continuous development of technology, smart locks are widely used in daily life. The common way to unlock smart locks is wireless unlocking, which requires users to perform operation authorization through the application to complete the unlocking action, or to use the method of scanning the code to achieve it. However, these unlocking methods all rely on the network. If there is no signal in an environment, it cannot be unlocked normally. In addition, each unlocking requires the user to authorize, resulting in low unlocking efficiency and the entire operation process is complicated and tedious.

[0003] Although the existing Bluetooth senseless unlocking technology has improved the traditional unlocking method, it still has defects. For example, by using a low-power Bluetooth module that matches the mobile terminal and the lock, the distance is measured according to the collected Bluetooth signal strength value to unlock the door. However, it is difficult to determine whether the mobile terminal is inside or outside the door. In actual situations, when the user operates the mobile terminal device inside the door or charges it, the lock may be unlocked by mistake, which undoubtedly brings security risks. In addition, unlocking based on distance will also violate the user's subjective will. For example, when the user changes shoes outside the door, locks the door and leaves, or returns to the door, the lock will automatically unlock, which also poses a security risk that cannot be ignored. Summary of the invention

[0004] In view of this, the embodiments of the present invention provide a method, device, computer equipment and storage medium for unlocking a smart door lock to solve the problems that the existing smart lock wireless unlocking method relies on the network, has low unlocking efficiency, is cumbersome to operate, and the Bluetooth non-sensing unlocking technology is difficult to determine the location of the mobile terminal, which may easily lead to the lock being mislocked.

[0062] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0063] According to an embodiment of the present invention, a method, apparatus, computer device and storage medium for unlocking a smart door lock are provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that shown here.

[0064] In this embodiment, a method for unlocking a smart door lock is provided. Figure 1 : is a flow chart of an unlocking method of a smart door lock according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0065] Step S11, receiving a Bluetooth signal sent by a mobile device within a preset range of the smart door lock, wherein the Bluetooth signal includes a first signal and a second signal, the first signal is received by a Bluetooth antenna set in the front panel of the smart door lock, and the second signal is received by a Bluetooth antenna set in the rear panel of the smart door lock.

[0066] It should be noted that the smart door lock is mainly composed of a front panel, a rear panel and a lock body. The front panel is installed on the outside of the entrance door, the lock body is embedded inside the entrance door, and the rear panel is installed on the inside of the entrance door. Figure 2 As shown, a trigger operation detection unit is provided at position 1 on the smart door lock handle, and Bluetooth antennas are provided at position 2 on the front panel and position 3 on the rear panel.

[0067] In an embodiment of the present application, receiving a Bluetooth signal sent by a mobile device within a preset range of the smart door lock includes the following steps A1-A3:

[0068] Step A1, obtaining parameter information of the smart door lock.

[0069] Specifically, the parameter information of the smart door lock is critical to its Bluetooth communication and unlocking process with the mobile device, including but not limited to: first, its own identification parameters, such as the device serial number, model, etc., to facilitate accurate identification, avoid confusion, and ensure accurate interaction; second, the configuration parameters of the Bluetooth communication module, such as the frequency band, transmission power range, etc., determine the signal propagation and connection capabilities, which are conducive to controlling the signal coverage and communication stability and effectiveness; third, the relevant parameters of the interaction protocol with the mobile device, such as the Bluetooth protocol version, data transmission encryption method and key information, etc., to ensure data security, protect privacy and control security; fourth, the relevant parameters of the internal distance, such as the effective distance range value that can receive the mobile device signal, which is conducive to determining the search and connection range, and improving communication efficiency and accuracy. After obtaining these parameter information, the smart door lock can generate a wake-up signal based on this, start the Bluetooth interaction process, and prepare for the subsequent steps.

[0070] Step A2: Generate a wake-up signal using the parameter information, and send the wake-up signal to mobile devices within a preset range.

[0071] Specifically, the smart lock generates a specific wake-up signal through its built-in signal generation algorithm based on the acquired parameter information of itself. The wake-up signal contains the identity information of the smart lock and some basic parameter information related to the current interaction. The Bluetooth module of the smart lock will send this wake-up signal in the form of a specific Bluetooth broadcast to the surrounding preset range (for example, a circular area with a radius of 10 meters centered on the smart lock). Within this range, if there is a mobile device that has been bound to the smart lock, its Bluetooth function is turned on and in a standby mode that can be awakened, it can receive this wake-up signal. For example, when the user's mobile phone is bound to the smart lock, the Bluetooth chip of the mobile phone will continue to monitor the surrounding Bluetooth signals. After receiving the wake-up signal sent by the smart lock, it will trigger the relevant response program on the mobile phone to prepare for subsequent Bluetooth signal interaction operations with the smart lock.

[0072] Step A3, receiving a first signal fed back by the mobile device through the Bluetooth antenna on the front panel of the smart door lock, and receiving a second signal fed back by the mobile device through the Bluetooth antenna on the rear panel of the smart door lock.

[0073] Specifically, Figure 3As shown, the smart door lock consists of a control unit, a storage unit, a Bluetooth SoC, a trigger operation detection unit, a front panel Bluetooth antenna, and a rear panel Bluetooth antenna, and it communicates with the mobile device. After the smart lock sends a wake-up signal, the mobile device will feedback a signal. The front and back panels of the smart lock have Bluetooth antennas that can receive the Bluetooth signal of the mobile device for precise location and signal analysis. The feedback signal of the mobile device is received by the two antennas of the smart lock, which are the first signal and the second signal. These signals contain information such as the identity of the mobile device and the signal strength. The smart lock determines the position of the mobile device relative to the door based on this.

[0074] Step S12, judging whether the user is outside the front panel of the smart door lock based on the first signal and the second signal, includes the following steps B1-B3:

[0075] Step B1, calculating the intensity difference between the first signal and the second signal.

[0076] Specifically, after the smart lock receives the first signal through the front panel Bluetooth antenna and the second signal through the rear panel Bluetooth antenna, it is necessary to quantify the strength of the two signals. Signal strength refers to the amount of energy carried by the Bluetooth signal during propagation, usually measured in specific units (such as dBm, decibel milliwatts). The signal processing module inside the smart lock calculates the strength difference between the first signal and the second signal. For example, if the strength of the first signal is -60dBm and the strength of the second signal is -70dBm, the strength difference between them is 10dBm. By continuously monitoring and calculating such strength differences, the smart lock can more accurately grasp the relative position relationship between the mobile device and the door and the stability of signal transmission, providing key basis for subsequent judgment and operation.

[0077] Step B2, comparing the intensity difference with a preset threshold.

[0078] Specifically, the preset threshold is a key numerical standard pre-set by the smart door lock system to distinguish the user's position. After the smart lock calculates the strength difference between the first signal and the second signal through its internal signal processing module, it is necessary to compare the calculated difference with the preset threshold to determine the position of the user relative to the front panel of the smart door lock reflected by the difference, thereby providing a basis for subsequent accurate judgment of whether the user is on the outside or inside of the door panel.

[0079] Step B3, if the strength difference is greater than the preset threshold, it is determined that the user is on the outside of the front panel of the smart door lock, or if the strength difference is less than the preset threshold, it is determined that the user is on the inside of the front panel of the smart door lock.

[0080] Specifically, if the difference in strength between the first signal and the second signal is greater than a preset threshold, the smart lock determines that the user is most likely outside the door. When the mobile device is outside the door, affected by the propagation path, obstacles, etc., the signal strength received by the front panel Bluetooth antenna is often stronger than that inside the door, and the difference exceeds the threshold, which meets the characteristics outside the door; if the strength difference is less than the preset threshold, the smart lock determines that the user is on the inside of the door panel. When the mobile device is inside the door, the rear panel Bluetooth antenna is closer to it, and the received signal strength will be higher or similar to that outside the door, and the difference is not large. This can distinguish the user's location and ensure that subsequent operations are reasonable and safe.

[0081] Step S13: If it is outside the front panel of the smart door lock, detect the user's trigger operation.

[0082] In the embodiment of the present application, when the user is determined to be outside the front panel of the smart door lock by analyzing the intensity difference between the first signal and the second signal, the system starts the detection process for the possible trigger operation of the user. The trigger operation detection unit set at the door handle associated with the smart door lock starts working, and the unit has multiple detection capabilities. For example, a pressure sensing device is used to detect whether the user has pressed the door handle or the surrounding area; a close-range sensing sensor can sense the movement of the user's hand or body approaching; a detection module with a biometric recognition function, such as a fingerprint recognition, a vein recognition sensor, etc., performs feature collection and recognition when the user performs the corresponding operation. Through these detection means, the user's behavior related to the intention to unlock the door in front of the door lock is captured, so that the user can further judge whether the user really wants to open the door lock based on the detected trigger operation, thereby providing key behavioral data basis for the precise unlocking control of the smart door lock, ensuring the safety and accuracy of the unlocking process of the smart door lock, preventing the occurrence of misjudgment or illegal unlocking, and improving the convenience and intelligent experience of users using smart door locks.

[0083] Step S14, determining whether the user has the intention to unlock the door according to the trigger operation, and controlling the smart door lock to perform the unlocking operation if the user has the intention to unlock the door.

[0084] In the embodiment of the present application, determining whether the user has the intention to unlock the door according to the trigger operation includes the following steps C1-C2:

[0085] Step C1, determining the operation type of the triggering operation, wherein the operation type includes a contact type and a non-contact type.

[0086] Specifically, in the use scenario of smart door locks, there are many forms of triggering operations for users to interact with door locks. Contact-type operations usually refer to the operation behavior generated by users directly touching the corresponding sensing area, buttons, door handles and other parts of the door lock through body parts (such as fingers). Pressing the fingerprint recognition area, pressing the physical unlocking button, holding the door handle, etc. are all such contact triggering operations. This operation is usually accompanied by physical contact actions and corresponding mechanical feedback. Non-contact-type operations do not require direct contact with the door lock, and use other methods to trigger the door lock sensing. For example, using face recognition technology, the user only needs to stand within a certain range in front of the door lock to allow the door lock camera to capture facial features; or through eye recognition, gaze at a specific area of ​​the door lock to achieve the purpose of triggering, or through some technologies with near-field sensing functions, when the user approaches a certain distance, the door lock sensing is triggered, etc., and these operations do not require direct physical contact. Accurately judging the type of operation through this step can lay the foundation for the subsequent use of corresponding analysis strategies based on different types to determine whether the user has the intention to unlock, making the entire judgment process more targeted and accurate.

[0087] Step C2: if the trigger operation is of contact type, determine whether the user's trigger operation has an unlocking intention based on the first analysis strategy; or, if the trigger operation is of non-contact type, determine whether the user's trigger operation has an unlocking intention based on the second analysis strategy.

[0088] Specifically, when the trigger operation is determined to be a contact type, the first analysis strategy is used to first obtain the pressing characteristics of the contact operation, such as the strength, number of presses, specific location, etc. Then the trigger mode is determined based on these characteristics. If the pressing intensity is within the first threshold range and a single press is a wake-up mode, only the related functions are awakened; if the pressing intensity is within the second threshold range and a double press is an unlocking mode, indicating an intention to unlock; if the pressing intensity is within the third threshold range and multiple presses are made, it is an alarm mode, indicating an abnormal or illegal operation, so as to determine whether the user wants to unlock the door under the contact type operation.

[0089] Specifically, if the trigger operation is of non-contact type, the second analysis strategy is enabled. First, eye features (such as the relative angle between the eyes and the door lock, the duration of the direct gaze state, etc.) are obtained, and then the trigger mode is determined according to the eye features: direct gaze and the duration is less than the first preset time is the wake-up mode; direct gaze and the duration is greater than or equal to the first preset time is the unlocking mode, which means there is an intention to unlock the door; non-direct gaze and the duration is greater than or equal to the second preset time is the alarm mode, so as to accurately judge the user's intention to unlock the door and ensure the safe and reasonable use of the door lock.

[0090] In the embodiment of the present application, determining whether the user's triggering operation has an unlocking intention based on the first analysis strategy includes the following steps D1-D3:

[0091] Step D1, obtaining a pressing feature associated with a triggering operation.

[0092] Specifically, the pressing characteristics include pressing intensity, pressing duration and pressing mode. Pressing intensity refers to the amount of pressure applied by the user's finger on the door handle, which is measured by the pressure sensor in the smart lock's finger pressing detection unit. Different pressure values ​​reflect different operating intentions. Light touches are mostly unconscious contacts, while greater pressure indicates a clear operating requirement. Pressing duration is the length of time from when a finger contacts the door handle and applies pressure to when the finger is released. Recording this duration can analyze the operating rhythm. A short press may be a quick confirmation operation, while a longer press may be waiting for feedback or performing a specific setting operation. Pressing modes include continuous pressing, intermittent pressing, etc. Continuous and rapid multiple presses can try to trigger specific functions such as alarm functions. Regular intermittent presses correspond to other operating instructions such as entering the setting interface.

[0093] Step D2, determining the trigger mode of the smart door lock according to the pressing characteristics.

[0094] In the embodiment of the present application, step D2 specifically includes the following steps D21-D23:

[0095] Step D21, if the pressing feature is that the pressing intensity is within the first threshold range and is a single press, it is determined that the trigger mode of the smart door lock is the wake-up mode.

[0096] Specifically, the first threshold range refers to a reasonable pressure value interval set after a lot of testing and actual application data analysis. When the user's pressing intensity falls within this range and the pressing action is performed once (that is, only pressed once), the smart lock will determine that the user's operation intention at this time is just to wake up the smart lock system, so that it can enter the ready state from the standby state to receive subsequent operation instructions. For example, in daily life, the user just taps the door handle to observe whether the smart lock is in normal working condition or ready for the next unlocking operation. In this case, the smart lock will enter the wake-up mode, light up the relevant indicator light or emit a slight prompt sound, etc., to inform the user that the system is ready to receive subsequent instructions.

[0097] Step D22, if the pressing feature is that the pressing intensity is within the second threshold range and it is double-clicked, it is determined that the trigger mode of the smart door lock is the unlocking mode.

[0098] Specifically, the second threshold range is also a specific pressure value interval, but unlike the first threshold range, it corresponds to the user's high willingness to open the door lock. When the user presses the door handle with a pressure intensity within this range and double-clicks the door handle, the smart lock will recognize that this combination of pressing features is most likely a clear unlocking request from the user. For example, when the user normally wants to open the door, he will quickly double-click the door handle with a relatively moderate force that is in line with daily habits. At this time, the smart lock will determine that it has entered the unlocking mode and prepare for subsequent Bluetooth signal verification and unlocking operations.

[0099] Step D23, if the pressing feature is that the pressing intensity is within the third threshold range and is pressed multiple times, it is determined that the trigger mode of the smart door lock is the alarm mode.

[0100] Specifically, the third threshold range refers to a relatively large pressure value interval. When the user's pressing intensity reaches this range and the pressing operation is performed multiple times (such as more than 3 times), the smart lock will consider that there is an abnormal situation, such as someone trying to forcibly destroy the door lock or too frequent misoperation. In this case, the smart lock will immediately enter the alarm mode, triggering the built-in alarm to emit a loud alarm, and also send an alarm notification to the user's mobile phone and other devices through the connection with the home security system to attract the attention of people around and take corresponding measures to ensure home safety.

[0101] Step D3: when the trigger mode is the unlocking mode, determining that the user has the intention to unlock.

[0102] Specifically, when the trigger mode of the smart door lock is determined to be the unlocking mode, the pressing characteristics meet the unlocking request conditions (such as pressing strength, double-click pressing, etc.), indicating that the user's intention is to open the smart door lock.

[0103] In the embodiment of the present application, determining whether the user's triggering operation has an unlocking intention based on the second analysis strategy includes the following steps E1-E3:

[0104] Step E1, obtaining eye features associated with the triggering operation.

[0105] Specifically, in non-contact operation scenarios, such as when interacting with a smart door lock through eye recognition, the door lock's related sensing devices (such as cameras and other components with image acquisition and analysis functions) will capture and monitor the user's eye status. Eye features include but are not limited to the relative angle between the user's eyes and the door lock, which is used to determine whether the user is in a straight-on state, as well as key information such as the length of time in a certain state (such as straight-on or other related states). Collecting this eye feature information provides a basic data basis for subsequent judgment of the trigger mode of the smart door lock and further determination of the user's intention to unlock the door, and is the starting point of the entire judgment process based on the second analysis strategy.

[0106] Step E2, determining the triggering mode of the smart door lock according to the eye features.

[0107] In the embodiment of the present application, step E2 includes the following steps E21-E23:

[0108] Step E21, if the eye feature is in a normal gaze state and the duration is less than a first preset time, it is determined that the trigger mode of the smart door lock is a wake-up mode.

[0109] Specifically, in actual usage scenarios, when the smart door lock senses that the user is looking directly at it, but the duration of the gaze is relatively short and has not reached a specific duration (i.e., less than the first preset time), it means that the user may have only looked at the door lock inadvertently or briefly, such as passing by with his eyes. In this case, it only causes the door lock to initially sense and enter the wake-up mode. In the wake-up mode, the door lock can only activate the screen display, light up the relevant indicator lights and other basic operations, so that the door lock enters the state of preparing to receive further operation instructions from the standby state, but it does not mean that the user has the intention to unlock the door at the moment, it is just a shallow interactive state.

[0110] Step E22, if the eye feature is in a normal gaze state and the duration is greater than or equal to the first preset time, it is determined that the trigger mode of the smart door lock is an unlocking mode.

[0111] Specifically, when the door lock detects that the user is looking directly at it and the duration of this looking state reaches or exceeds a preset time (first preset time), this is consistent with a common eye behavior characteristic during normal unlocking, indicating that the user is likely to intentionally stand in front of the door and convey the intention to unlock the door through eye gaze. Therefore, the trigger mode of the smart door lock is judged as unlocking mode at this time, and the subsequent system will perform the unlocking operation based on this, so as to adapt to the normal unlocking usage scenario.

[0112] Step E23, if the eye feature is a non-rectilinear state and the duration is greater than or equal to a second preset time, the trigger mode of the smart door lock is determined to be an alarm mode.

[0113] Specifically, if the door lock detects that the user's eyes are not in a straight-ahead state (for example, blinking, squinting, wandering eyes, etc.), and it lasts for a long time (greater than or equal to the second preset time), this situation may be abnormal. For example, someone has been wandering near the door lock for a long time but has not had the reasonable behavior of looking straight at the door lock. It may be that someone is trying to understand the situation of the door lock through improper means or has other abnormal behaviors. To ensure safety, the trigger mode of the smart door lock is set to the alarm mode at this time, triggering the corresponding alarm prompt (such as sounding an alarm, sending abnormal reminder information to the associated mobile phone, etc.) to remind users or relevant personnel to pay attention to possible safety hazards.

[0114] Step E3: when the trigger mode is the unlocking mode, determining that the user has the intention to unlock the door.

[0115] Specifically, no matter it is a contact type trigger operation or a non-contact type trigger operation, when it is determined that the trigger operation has an unlocking intention, it can be determined that the user has an unlocking intention.

[0116] In the embodiment of the present application, after receiving the Bluetooth signal sent by the mobile device within the preset range of the smart door lock, the method further includes F1-F3:

[0117] Step F1 obtains identification information of the mobile device.

[0118] Specifically, the smart lock obtains the identification information of the mobile device. The identification information refers to the MAC address (Media Access Control Address, MAC) of the Bluetooth of the mobile device. The smart lock extracts the MAC address from the received Bluetooth signal through the Bluetooth connection protocol established between the smart lock and the mobile device, so as to match and verify it with the pre-stored binding terminal information, thereby determining whether the mobile device is a legitimate device authorized to unlock the smart lock.

[0119] Step F2, matching the identification information with the pre-stored binding terminal information to obtain a matching result.

[0120] Specifically, the smart lock storage unit pre-stores all the legal mobile terminal information bound to it, including identification information such as Bluetooth MAC address. After obtaining the identification information of the current mobile device, the matching verification program will be started to carefully compare each character and each group of numbers according to specific algorithms and rules. If it completely matches a certain pre-stored information, the result is a successful match, otherwise it is a failed match. Only when the match is successful, it indicates that the current mobile device is an authorized and legal device, and the subsequent unlocking operation can be promoted.

[0121] Step F3, when the matching result is successful, determine whether the user is outside the front panel of the smart door lock based on the Bluetooth signal sent by the mobile device.

[0122] Specifically, when the mobile device identification information (Bluetooth MAC address) successfully matches the pre-stored binding terminal information, it indicates that it is a legal unlocking device. At this time, the smart door lock uses the Bluetooth signal sent by the mobile device, which includes the first signal received by the front panel Bluetooth antenna and the second signal received by the rear panel Bluetooth antenna, to analyze and determine whether the user is on the outside of the door panel. Only when the user is on the outside, the subsequent analysis and judgment of the door handle pressing operation and the related unlocking process are meaningful. If the user is on the inside, it does not comply with the unlocking logic outside the door, and the smart door lock does not need to perform unlocking-related operations, thereby ensuring security and the rationality of the unlocking logic.

[0123] As an example, Figure 4 As shown, first scan the Bluetooth devices within the preset range. Then determine whether there is an authorized device that has been paired among these Bluetooth devices. If not, the process ends; if so, detect whether the authorized device has enabled the convenient unlocking function. Then obtain the location information of the authorized device, and then determine whether the authorized device is outside the front panel of the smart door lock. If not, the process ends; if it is outside, detect the user's trigger operation, and finally the process ends.

[0124] In the embodiment of the present application, the method further includes the following steps S21-S23:

[0125] Step S21, obtaining the user's historical pressing features.

[0126] In the embodiment of the present application, the historical pressing feature refers to a series of characteristic information presented by the user's pressing operation on the door handle when using the smart lock in the past, which may include historical pressing intensity, historical pressing duration, and historical pressing mode. The smart lock will continuously update and save these historical pressing feature information through its built-in storage unit, providing a rich data basis for subsequent analysis of user behavior patterns and personalized settings based on user habits.

[0127] Step S22, comparing the pressing characteristics of the user's current pressing operation with the historical pressing characteristics to obtain a comparison result.

[0128] In the embodiment of the present application, after the user performs a new pressing operation on the door handle associated with the smart door lock, the pressing intensity, duration, pressing mode and other characteristics of this operation will be obtained, and compared with the historical pressing characteristics stored previously. In terms of pressing intensity, it is to see whether there is a large deviation between the current pressure value and the historical average pressing intensity in the same or similar situations (such as the same time period, the same door opening direction, etc.); the duration is to compare whether the duration of this pressing is consistent with the duration of the common door opening operation in the past; the pressing mode checks whether the current method is consistent with the commonly used mode in the past. After this comparison process, the smart lock can obtain a comparison result of the degree of difference between the current pressing operation and the historical pressing habits. If the two are basically consistent, it means that this operation is in line with the usual door opening habits. If there is a difference, it means that there are special circumstances or changes in operating habits in this operation.

[0129] Step S23: If the comparison result shows that the pressing feature is inconsistent with the historical pressing feature, the mode adjustment mechanism is triggered to adjust the threshold range associated with the trigger mode according to the pressing feature to obtain an adjusted threshold range.

[0130] In an embodiment of the present application, if the comparison result shows that the current pressing feature is inconsistent with the historical pressing feature, the smart lock will start the mode adjustment mechanism. This mechanism is its built-in intelligent algorithm and program logic, which will dynamically adjust the relevant settings of the smart door lock according to the user's current operation and historical habit changes. For example, if the current pressing intensity is significantly higher than the historical average intensity and it happens many times, it may be due to changes in operating habits or special circumstances (such as holding heavy objects) that require greater pressure to press. At this time, the mode adjustment mechanism can correspondingly increase the trigger mode threshold range related to the pressing intensity, that is, the second threshold range used to judge the unlocking mode is appropriately adjusted according to the actual situation, so that the user can still successfully trigger the corresponding mode under the new habit. Similarly, if the current pressing duration or pressing mode is very different from the historical situation, the corresponding threshold range is also reasonably adjusted according to the specific difference to obtain the adjusted threshold range, so that the smart lock can flexibly adapt to changes in user operations.

[0131] In the embodiment of the present application, the method further includes the following steps S31-S33:

[0132] Step S31, obtaining the unlocking frequency of the mobile device within a preset time period.

[0133] In the embodiment of the present application, the smart lock will continuously track and record each time a mobile device interacts with it to unlock through its built-in recording and statistics function. When it comes to judging the unlocking frequency of a mobile device, it will accurately count the number of times the mobile device completes unlocking during the preset time period at the end of the preset time period (or count in real time at a certain time interval, depending on the system settings), thereby obtaining the key data of the unlocking frequency of the mobile device during the preset time period. For example, if the preset time period is set to one month, then at the end of each month, the smart lock will count the number of times a mobile phone bound to it successfully unlocks the smart lock during that month, and this number is the unlocking frequency of the mobile device in that month.

[0134] Step S32: when the unlocking frequency is lower than the preset frequency, it is determined that the mobile device has a security risk, and an identity authentication mechanism is triggered to authenticate the user and obtain a verification result.

[0135] In an embodiment of the present application, under normal use, if the mobile device is always under the normal control of the user and the usage habits are relatively stable, the unlocking frequency within the preset time period should be maintained at a relatively reasonable level. When the unlocking frequency is too low, it means that an abnormal situation has occurred in the mobile device, such as the device is lost, stolen, or the user has not used the device normally to interact with the smart lock for a long time. When it is determined that there is a security risk in the mobile device, the smart lock triggers the identity authentication mechanism. The identity authentication mechanism can include multiple verification methods, such as requiring the user to enter a pre-set password, verification through biometric information bound to the mobile device (such as fingerprints, facial recognition, etc.), etc.

[0136] Step S33, if the verification result is that the verification is passed, the smart door lock is controlled to perform the corresponding unlocking operation and update the unlocking frequency of the mobile device; or, if the verification result is that the verification fails, the unlocking operation is rejected and a reminder operation is performed.

[0137] In the embodiment of the present application, if the verification is successful, indicating that the user is legitimate, the smart lock control unit will start the unlocking operation to open the door smoothly, and after the unlocking is completed, the unlocking frequency of the mobile device within the current preset time period will be updated, such as from the previous 2 times to 3 times, so as to facilitate the subsequent judgment of its usage. If the verification fails, it means that the user may be suspected of illegal operation. The smart lock will refuse to unlock to ensure home safety, and will also perform reminder operations in the form of displaying prompt information on the display screen or sending messages to the mobile device, so that the user knows the situation and takes corresponding measures, such as checking the password, confirming whether the device has been stolen, etc., so as to ensure safety and let the user know the problem in time.
