Description

Technical Field

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

[0002] With the rapid development of science and technology, smart home products have gradually entered thousands of households. As an important part of them, smart door locks have been widely used in people's lives. Its functions are also continuously expanding and upgrading, becoming increasingly rich and diverse. Today, smart door locks are no longer limited to the traditional simple unlocking function. They continue to deepen their security and add many comprehensive and practical functions, such as advanced biometric technology to improve the convenience and safety of unlocking, and smart monitoring and alarm systems to protect home safety. These functions provide more convenience and solid protection for people's lives in all aspects, greatly changing people's perception and experience of traditional door locks.

[0003] However, the current security functions of smart locks still have obvious limitations in practical applications. Although it has a series of practical security functions such as no-test alarm, stay alarm, doorbell call, etc., most of these functions rely on the APP that matches the lock to realize information display and interaction. The reality is that many users do not actively open the APP to check relevant information every day due to factors such as the fast pace of life and operating habits. This means that when the door lock detects abnormal events or important interactive events, the key security information that should be conveyed to the user in a timely manner cannot be effectively transmitted because the user fails to check the APP in time, resulting in the value of these practical functions of the smart lock cannot be fully demonstrated, and it fails to fully play its due protection role, which to a certain extent weakens the actual effectiveness of the smart door lock in protecting the user's life safety. Summary of the invention

[0051] 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.

[0052] According to an embodiment of the present invention, a video recording method, apparatus, computer device and storage medium for 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 can be executed in an order different from that shown here.

[0053] In this embodiment, a video recording method for a smart door lock is provided. Figure 1 is a flow chart of a video recording method for a smart door lock according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0054] Step S11, when the event backtracking function of the smart door lock is in an enabled state, detecting a triggering event for the smart door lock.

[0055] In the embodiment of the present application, the event backtracking function refers to the recording and storage of relevant circumstances before and after the smart door lock detects a specific triggering event, so that users can trace back and view the whole picture, and obtain details on the use of the door lock and the surrounding security. Specifically, the smart door lock collects door lock related information in real time through built-in sensors such as doorbells, peepholes, and lock cylinder status. When someone presses the doorbell, the peephole detects someone staying, or the lock cylinder is unlocked abnormally, the corresponding sensor will detect it and feed it back to the system as a triggering event. These sensors perceive the dynamics of the door lock in all directions, identify events that may affect the safety or normal use of the door lock, and provide original information for subsequent processing. This step is the starting point of the smart door lock event processing mechanism, which ensures timely detection of various important events and lays the foundation for subsequent analysis, recording, and information presentation.

[0056] Step S12: determine whether the triggering event has a backtracking requirement based on a preset analysis strategy.

[0057] In the embodiment of the present application, step S12 includes the following steps A1-A2:

[0058] Step A1, obtaining the data source of the triggering event.

[0059] Specifically, the data source of the trigger event is the various sensors built into the smart door lock, each of which keenly captures different trigger event information. If the trigger event is the doorbell being pressed, the doorbell sensor senses the pressure change and converts the doorbell pressing action into an electrical signal and transmits it to the smart door lock control system. The electrical signal carries the relevant data. If the trigger event is someone staying in front of the door, the cat's eye sensor uses camera imaging technology to monitor the area in front of the door. When it detects that a person remains relatively still for a certain period of time and determines that someone is staying, the relevant image and time information are used as the relevant data of the trigger event. If the trigger event is the lock cylinder unlocking operation, the lock cylinder status sensor senses the abnormal changes in parameters such as force, angle, and frequency when the lock cylinder rotates. These abnormal parameter information is the relevant data of the trigger event.

[0060] Step A2: determine the corresponding preset analysis strategy according to the data source, and determine whether the triggering event has a backtracking requirement according to the preset analysis strategy.

[0061] Specifically, after obtaining the source of the trigger event data, the smart door lock calls the corresponding preset analysis strategy according to different sources to determine the backtracking demand. For example, for the doorbell sensor data, if the doorbell is pressed multiple times in a short period of time (within 1 minute), and it may be combined with whether a specific user presses the bell and other conditions for comprehensive judgment, it may mean that the visitor is in a hurry, and it will be regarded as an important interaction event with a higher backtracking demand; the cat's eye sensor detects the stay information of the person. If the stay exceeds the preset threshold (30 seconds, shortened to 15 seconds when there is a courier package at the door), or the person has abnormal behaviors such as wandering and peeping, it will be required to backtrack due to security issues; the lock cylinder status sensor transmits abnormal unlocking data, such as consecutive wrong password input reaches the preset number of times (3 times), or fingerprint, card swiping and other unlocking methods are abnormal, it will be regarded as a security threat, with a higher backtracking demand. These strategies help to comprehensively assess the importance and potential risks of the event, accurately determine whether to backtrack the record, avoid resource waste, and ensure that important information is not missed.

[0062] Step S13: If there is a need for backtracking, the environment outside the smart door lock is recorded based on the triggering event to obtain a recorded video.

[0063] In an embodiment of the present application, recording the environment outside the smart door lock based on a triggering event to obtain a recorded video includes the following steps B1-B3:

[0064] Step B1, if the triggering event is an interactive event, start the recording device of the smart door lock.

[0065] Specifically, when the smart door lock determines that the trigger event is an interactive event based on the preset analysis strategy, the recording preparation is started. Interactive events refer to behaviors that are directly interactive with users or visitors, such as doorbell calls, message reception and other scenarios. For example, when the doorbell sensor detects that the doorbell is pressed and determines that this is a doorbell call interactive event, the built-in recording device of the smart door lock will be started. The recording device can be a camera integrated in the cat's eye module or other equipment specifically used for recording such interactive events. By starting the recording device, preparations are made for the process of recording interactive events to ensure that the relevant screen information can be fully captured later.

[0066] Step B2, obtaining multiple image frames captured by the recording device, and monitoring the activities of people in the image frames.

[0067] Specifically, after the recording device is started, it will start to continuously collect image frames of the environment outside the door. These image frames can be connected to present the complete process of the event. At the same time, the smart door lock will use image analysis technology to monitor the collected image frames in real time, focusing on whether there is human activity in them. For example, by analyzing the displacement, shape change and other features of objects in the image, it can be determined whether there is a person moving or making movements in the picture. If it is detected that there are people walking or raising their hands in the picture, it means that there is human activity.

[0068] Step B3, when there is no human activity in the image frame, turn off the recording device to obtain a recorded video.

[0069] Specifically, when no human activity is detected in the continuous image frames, it indicates that the current stage of the interaction event has ended. For example, a visitor presses the doorbell, communicates with the people in the house, and then leaves, and there is no one in the picture. At this time, in order to save storage space and system resources, the smart door lock automatically turns off the recording device and generates a video that fully records the interaction event. The video covers the screen from the beginning of the event (such as pressing the doorbell) to the end of the human activity, which is convenient for users to view later and understand the visitor's appearance, communication actions and other specific circumstances.

[0070] In an embodiment of the present application, recording the environment outside the smart door lock based on a triggering event to obtain a recorded video includes the following steps C1-C3:

[0071] Step C1: if the triggering event is an abnormal event, determine the abnormal type of the abnormal event.

[0072] Specifically, after determining that the trigger event is an abnormal event, its specific type needs to be determined. If the cat's eye sensor detects that the person in front of the door stays for more than the preset threshold (normally 30 seconds, shortened to 15 seconds in specific scenarios such as express packages at the door), it is determined to be a stay type abnormal event, because a long stay may have potential risks such as strangers snooping into the house. When the user unlocks the door, if the wrong password is entered continuously for a preset number of times (such as 3 times), or the unlocking method such as fingerprint or card swiping is abnormal (such as forged fingerprint, card abnormality), it is determined to be a forbidden type abnormal event, indicating that someone may illegally unlock the door, threatening the safety of the door lock. If the lock sensor senses the force of the lock picking tool, abnormal vibration or displacement change of the lock body, it is determined to be a lock picking type abnormal event, which is a direct security threat and needs to be recorded in time. When the user is forced to use a special unlocking method (pressing the hijacking alarm button or entering the hijacking password), or the smart door lock detects an abnormal change in the distance from the user's mobile device accompanied by abnormal door lock operation, it is determined to be a hijacking type abnormal event, because it involves the user's personal safety and requires special processing.

[0073] Step C2, determining a corresponding recording strategy according to the exception type.

[0074] Specifically, after determining the type of abnormal event, the smart door lock can call the adaptive recording strategy according to different types. For the stay type, if it is detected that the person stays for more than the preset time, the recording device will continuously record their behavior in all directions until they leave or the abnormal behavior ends; for the forbidden type, if the password is wrong or other unlocking anomalies are detected, the recording device will record the whole process from the beginning to the end of the attempt and the characteristics of the person, etc., and different users will be recorded in sequence if they enter the wrong password multiple times in a short period of time; for the prying type, the recording will be started when the prying action is detected, and multiple captured videos will be recorded and played to highlight the key moments after a certain period of time; for the hijacking type, if the trigger condition is detected and the captured video meets the playback condition, the recording device will record the situation from the triggering alarm to the subsequent situation in a timely manner, combined with details such as the distance between the device and the door lock operation, to provide a basis for ensuring safety and subsequent processing. These personalized strategies can capture key information to the greatest extent and improve the family's security protection capabilities.

[0075] Step C3, recording the environment outside the smart door lock based on the recording strategy to obtain a recorded video.

[0076] In the embodiment of the present application, if the abnormal type is a personnel abnormal type, the recording strategy is determined to be the first recording strategy, and step C3 includes the following steps C301-C303:

[0077] Step C301, detecting the behavior and stay time of people within the preset range of the smart door lock.

[0078] Specifically, the smart door lock uses the cat's eye module and other devices to continuously monitor the preset area in front of the door with a radius of several meters around the door lock and where human activities can be observed. During monitoring, on the one hand, it focuses on whether the person has abnormal behaviors such as wandering, peeping, squatting for a long time, such as pacing repeatedly, looking close to the cat's eye; on the other hand, through the built-in timing function of the cat's eye module, the time is counted from the time the person enters the preset range to the time he leaves, and the length of his stay is recorded.

[0079] Step C302: Analyze personnel behavior and residence time to obtain analysis results.

[0080] Specifically, when analyzing personnel behavior, the collected behaviors are compared with the preset normal behavior patterns. For example, short stays waiting for the door to open, leaving quickly after putting down the package, etc. are normal behaviors. If they do not meet normal behaviors, such as aimless wandering for a long time, sneaky movements, etc., they are marked as abnormal tendencies. Analyze the dwell time. According to the reasonable time standards for different scenarios, when there is no interaction in normal visitor scenarios, if it exceeds 30 seconds (normal threshold) or in specific scenarios (such as express packages at the door), it exceeds 15 seconds, which is considered abnormal. Comprehensive behavior and dwell time analysis are used to determine whether the personnel behavior is abnormal.

[0081] Step C303: If the analysis result is abnormal behavior, the environment outside the smart door lock is recorded until the end of the human behavior is detected to obtain a recorded video.

[0082] Specifically, when the smart door lock determines that a person's behavior is abnormal, in order to retain key information, the recording program is immediately started and the environment outside the door begins to be recorded. The recording continues from the time the abnormality is determined until the person leaves the preset range, or the abnormal behavior stops and there is no new abnormal behavior for a period of time. For example, if a stranger is detected wandering around or peeping in front of the door for a long time, the recording will start after the abnormality is determined and will not stop until the person finally leaves.

[0083] In the embodiment of the present application, if the abnormality type is a door lock abnormality type, the recording strategy is determined to be the second recording strategy, and step C3 includes the following steps C311-C313:

[0084] Step C311, detecting physical signals of key structures in the smart door lock.

[0085] Specifically, the smart door lock is equipped with a variety of high-precision sensors to detect in real time the physical signals of the key structures such as the lock core, lock tongue and connecting parts that ensure the normal operation and safety protection of the door lock. For example, when the lock core rotates, the sensor monitors its torque, angle, acceleration, etc., and uses the signal data in a specific range during normal unlocking as the reference standard. Abnormal and violent twisting of the lock core will cause the sensor to capture the out-of-range change signal; the sensor at the lock tongue senses its position, speed, and force when it pops up or retracts. When the door lock is hit by external force or pried abnormally, the lock tongue state change signal will be detected in time; the connecting parts also have sensors to monitor their vibration frequency, amplitude and other signals. When the door lock is subjected to abnormal vibration, these signals are immediately fed back to the control system.

[0086] Step C312, determine whether there is a protection risk for the smart door lock based on the physical signal.

[0087] Specifically, after obtaining the physical signals of the key structures, they are compared and analyzed with the safety standards formulated based on a large amount of experimental data and the physical signal characteristics of door locks in normal usage scenarios. If the detected physical signals, such as the torque and angle of the lock core rotation, the action and position of the lock tongue popping out and retracting, and the vibration amplitude and frequency of the connecting parts, all meet the safety standards, it is determined that the door lock is working normally and there is no protection risk; if the signal deviates from the standard, such as a sudden increase in the lock core torque, abnormal displacement of the lock tongue, abnormal and violent vibration frequency of the connecting parts, etc., it is determined that the door lock may be subject to abnormal operations such as prying and violent opening, and there is a protection risk.

[0088] Step C313: If there is a protection risk, the environment outside the smart door lock is recorded until the preset termination condition is met to obtain a recorded video.

[0089] Specifically, if the smart door lock determines that there is a protection risk, in order to record the security incident, it will immediately record the environment outside the door in all directions through the recording equipment integrated in the cat's eye module or other special camera devices. The recording continues until the preset termination condition is met, where the preset termination condition can be that the door lock protection risk is lifted, that is, the physical signal of the key structure returns to normal, or it can be that the preset maximum recording time (such as 5 minutes or 10 minutes) is reached to avoid excessive use of storage resources. The recorded video fully records information such as abnormal people outside the door, behavioral actions, and changes in the surrounding environment. It is crucial for users to understand the risk status of the door lock, and can provide a strong basis for subsequent security assessments and alarm processing.

[0090] Step S14, when the playback condition corresponding to the triggering event is met, the smart door lock is controlled to perform the playback operation of the recorded video.

[0091] In the embodiment of the present application, the lock application of the smart door lock is provided with relevant configurations of the event backtracking function. Figure 2 As shown in the figure, trigger events (including doorbell calls, messages, etc.) have corresponding on and off options, and different user types (designated, any user opening the door) have different playback condition settings, as well as abnormal door opening warning prompts (the same type or total alarm exceeds the preset number in a day, and an alarm will be triggered after the designated user opens the door to prompt abnormalities). These playback conditions are preset in the door lock, and each trigger event corresponds to a different configuration. When a trigger event occurs, the door lock will judge according to the preset conditions. If it is met, it will control the playback of the corresponding recorded video. For example, when a doorbell call is triggered and meets the conditions of the designated user opening the door option, after the designated user opens the door, the door lock will play the doorbell call capture video. When playing, the video is extracted from the storage module and played through the rear panel display module. There are also video category prompts for user viewing.

[0092] In terms of playback settings, after the event backtracking function is turned on and the playback conditions are met, the rear panel display module classifies the qualified videos and plays them one by one. Before playing each type of video, a category prompt is displayed, and you need to manually click the play button to confirm. If you do not want to play a certain type of video, you can turn off the backtracking function of that type in the APP, or press and hold the setting key of the rear panel display module during playback to skip. If you need to review the played video, you can view it in the APP, or click the setting key of the rear panel display module to select the video type for replay. If the video is not played on the same day, you will be reminded continuously the next day until it is played actively. The video is stored in a loop, and the old video is overwritten when the space is full. The number of playbacks for each type of video can be set in the APP, and the latest one will be played first. If the number exceeds the limit, it will be viewed in the APP.

[0093] In terms of door opening alarm prompt, a separate alarm tone is set. After the trigger, the panel display module can be set to actively play the abnormal video captured, and the video can be viewed repeatedly in the APP. The playback conditions of different trigger events are as follows: Doorbell call, the designated user door opening option requires the doorbell to be pressed and the caller is in the designated list. In addition, it can be set that the designated user presses the doorbell from 11 pm to 6 am to play and prompt first; the option for any user to open the door is that the doorbell is pressed and the cat's eye capture is successful, and multiple doorbell presses within 1 minute are played in sequence. In terms of messages, the new message generates a prompt video to meet the playback conditions. The message of a specific user can be played by the designated recipient in the specified way, and the message of an unspecified user can be played by any user when the door is opened. Stay capture, the stay time exceeds the preset threshold (normal 30 seconds, 15 seconds for specific scenes such as express parcels at the door) or abnormal behavior is detected, and the captured video meets the playback conditions. Prohibited trial capture, the password is entered incorrectly for 3 times or other unlocking methods are abnormal, and the captured video can be played and marked. Anti-prying snapshot: when the lock picking action is detected, the snapshot is started, and multiple videos are played for more than 10 seconds and the key scenes are highlighted. Anti-hijacking alarm: when the special unlocking method or the distance between the lock and the mobile device and the door lock operation are abnormal, the snapshot video meets the conditions (can be triggered manually) to assist in judging the hijacking situation.

[0094] In the embodiment of the present application, before the playback condition corresponding to the triggering event is met, the method further includes steps D1-D4:

[0095] Step D1, determining a corresponding preset playing condition according to a triggering event.

[0096] Specifically, the smart door lock system has a built-in predefined rule set to set playback conditions for various trigger events. Taking the doorbell call as an example, its playback conditions are determined by the lock APP settings. Under the designated user door opening option, the doorbell must be pressed and the caller must be in the designated list for the captured video to be played; under the arbitrary user door opening option, the doorbell is pressed, the cat's eye capture is successful, and the doorbell is pressed multiple times within 1 minute, and the video is played in sequence. In the message event, the new message generates a prompt video, which meets the playback conditions. There are differences in the playback conditions for messages from specific and unspecified users. Similarly, trigger events such as lingering capture, prohibited test capture, anti-pry capture, and anti-hijacking alarm each have specific preset playback conditions according to the APP settings. These conditions are set when the program is initialized and stored in the system configuration file, and can be quickly called when a trigger event occurs.

[0097] Step D2, obtaining user information pre-configured in the preset playback condition.

[0098] Specifically, after determining the preset playback conditions corresponding to the triggering event, the pre-configured user information is extracted from the relevant data. For example, in the scenario where the doorbell calls a designated user to open the door, the list of designated users is accurately obtained from the corresponding configuration data; under the playback conditions of a specific user's message, the designated recipient and other information are obtained. This user information is entered by the user through the lock or application settings, stored in the smart door lock storage module, and associated with the triggering event and the preset playback conditions. A specific index mechanism is used to locate and extract information from the storage module to prepare for comparison with the target user information that is actually unlocked.

[0099] Step D3, when an unlocking operation for the smart door lock is detected, the target user information is obtained, and the target user information is compared with the user information to obtain a comparison result.

[0100] Specifically, when the smart door lock detects an unlocking operation, the process of acquiring the target user information is started. This process can involve a variety of identification technologies, such as fingerprint recognition, password verification, card swiping recognition, etc. For example, if the user unlocks the door with a fingerprint, the fingerprint recognition module of the smart door lock will compare the collected fingerprint information with the fingerprint template stored in the system, confirm the user's identity, and obtain the corresponding user ID as the target user information. Then, the acquired target user information is compared with the user information extracted from the preset playback conditions. For example, if the user information in the preset playback conditions is a list of specified users, check whether the target user information is in the list. The comparison process will match field by field. If multiple user information fields are involved (such as user ID, fingerprint feature code, etc.), the information of the two is considered consistent only when all key information fields match. Finally, a clear comparison conclusion is drawn based on the comparison results, that is, whether the information is consistent.

[0101] Step D4: If the comparison result shows that the information is consistent, it is determined that the preset playback condition is met.

[0102] Specifically, when the target user information is compared with the user information in the preset playback condition, if the result shows that the information of the two is consistent, it means that the user corresponding to the current unlocking operation meets the user requirements set by the preset playback condition. For example, in the scenario of the doorbell calling the designated user to open the door option, if the target user information matches a user information in the designated user list, it can be determined that the preset playback condition of the trigger event is met, and then the corresponding recorded video is extracted from the storage module according to the predetermined process, and played through the rear panel display module. At the same time, according to the playback setting plan, the video category prompt and other information are displayed to facilitate the user to view the relevant video content.

[0103] In this embodiment, a video recording system for a smart door lock is provided.

For example, when an interactive event or an abnormal event is triggered, the outside scene is captured in real time to provide raw data for recording video;

[0108] The first transmission module 102 is used to transmit data between the modules of the smart door lock 100, including transmitting the image frames collected by the cat's eye module 101 to the storage module 103 for storage, and transmitting the recorded video in the storage module 103 to the rear panel display module 104 for playback, and performing data interaction with the second transmission module 202 of the mobile device 200;

[0109] The storage module 103 is used to store the image frames collected by the cat's eye module 101 to form a recorded video, using a circular storage method to overwrite the old video when the space is full, and also stores data such as preset playback conditions and pre-configured user information related to the trigger event;

[0110] The rear panel display module 104 is used to receive and play the recorded video transmitted by the first transmission module 102 when the playback conditions are met, and at the same time display information such as video category prompts according to the playback settings for user viewing.

[0111] Specifically, the mobile device 200 includes a configuration module 201 and a second transmission module 202;

[0112] Configuration module 201, used to receive user configuration operations for the video recording and playback functions of the smart door lock, such as turning on or off the event backtracking function, setting playback conditions for different trigger events (doorbell calls, messages, etc.), and entering and managing pre-configured user information (specified user lists, etc.);

[0113] The second transmission module 202 is used to transmit data between the mobile device 200 and the smart door lock 100, and transmits the configuration information, user information, etc. set by the configuration module 201 to the first transmission module 102 of the smart door lock 100, and at the same time receives the door lock status, video and other data from the first transmission module 102 for display or processing on the mobile device 200.
