Description

Technical Field

[0001] This invention relates to the field of smart home control technology, and in particular to a smart entrance door processing method, system, and smart entrance door based on the identification of entry behavior stages. Background Technology

[0002] With the development of smart home technology, smart entrance doors and smart locks are gradually becoming important security devices in homes and offices. Existing smart entrance door systems typically trigger door unlocking operations through password input, card swiping, biometric recognition, or remote control, and in some scenarios, they combine with front-door cameras to monitor the environment in front of the door, thereby achieving auxiliary management of the entry process.

[0003] In related technologies, existing solutions have attempted to combine door lock triggering events with door-front image acquisition and image processing to improve the monitoring effect during the entry process. For example, Chinese invention patent application CN119274254A (hereinafter referred to as Document 1) discloses a smart home door lock processing system. When a door lock input operation is detected, it triggers a wireless monitoring device to acquire the environmental image in front of the door. Through continuous optimization devices, directional analysis mechanisms, and dynamic conversion mechanisms, the system performs white balance processing, tilt correction, gradient filtering, and adaptive selection of smoothing algorithms on the acquired image to obtain an optimized image for uploading or display.

[0004] The solution in Reference 1 improves the image quality of the door-to-door monitoring screen to some extent, enabling relatively stable visual effects for images captured under different environmental conditions. However, from the perspective of the overall process of home security control, this type of technical solution still mainly revolves around image processing itself, and its door lock control logic still relies on door lock input triggers or single recognition results, lacking a systematic analysis of the entire process of home entry behavior. Summary of the Invention

[0005] The purpose of this invention is to provide a smart entrance door processing method, system, and smart entrance door based on the stage recognition of entrance behavior, addressing the shortcomings of existing technologies. It aims to perform staged recognition and continuous analysis of entrance behavior without relying solely on image optimization or single-trigger judgment, and to generate door lock control decisions based on the overall process of entrance behavior, thereby solving the problems of lack of overall constraints on the entrance behavior process and easy interference of abnormal behavior in existing technologies.

[0006] This invention achieves the above objectives through the following technical solution: a smart entry door processing method based on entry behavior stage recognition, comprising the following steps: Pre-entry sensing step: Collect entry sensing data in front of the smart entrance door to determine whether an entry behavior trigger event has occurred; Phase identification steps: After detecting the home entry behavior trigger event, the home entry process is divided into phases based on the home entry perception data, and a behavior phase identifier is generated to characterize the home entry behavior process. Continuous verification step: Based on the generated behavior stage identifier, the sequential order between adjacent behavior stage identifiers is continuously verified to determine whether the current home entry behavior meets the preset stage evolution relationship; State construction steps: If the continuity check passes, the behavior stage identifiers are constructed into a home visit behavior state sequence in chronological order; Credibility assessment step: Analyze the completeness and stage rationality of the home visit behavior based on the home visit behavior state sequence to generate a credibility assessment result for the home visit behavior; Decision generation steps: Generate a door lock control decision signal based on the credibility determination result of the entry behavior and the corresponding behavior stage identifier; Door lock execution steps: When the door lock control decision signal indicates that the door lock control operation is allowed, a door lock control command is output to drive the smart entrance door to perform the corresponding door lock action and update the entrance behavior state sequence to the entrance completed state.

[0007] Specifically, this method collects entry-sensing data in front of the smart entrance door through a pre-sensing step to determine if a genuine entry behavior trigger event exists, thus preventing the system from entering subsequent processing steps when no one approaches or there is no effective operation. After detecting an entry behavior trigger event, a stage identification step divides the entry process into stages and generates behavior stage identifiers to characterize the entry behavior process. This ensures that the entry behavior is no longer considered an isolated event but a behavioral process with temporal sequence and process meaning. A continuous verification step verifies the order between adjacent behavior stage identifiers to determine whether the entry behavior conforms to the preset stage evolution relationship, thereby identifying unreasonable behaviors such as skipping steps, reversing order, or abnormal repetition. If the continuous verification passes, a state construction step constructs the behavior stage identifiers into an entry behavior state sequence, enabling the system to reflect the overall evolution of the entry behavior over time. Furthermore, a credibility judgment step analyzes the completeness and stage rationality of the entry behavior based on the entry behavior state sequence, generating an entry behavior credibility judgment result, providing a quantitative basis for door lock control. Based on this, a door lock control decision signal is generated by combining the credibility judgment result of the entry behavior and the current behavior stage identifier through the decision generation step. In the door lock execution step, the smart entry door is driven to perform the corresponding door lock action according to the door lock control decision signal. At the same time, the entry behavior state sequence is updated to the entry completion state, thus forming a complete entry processing closed loop.

[0008] Furthermore, in the pre-sensing step, the entry sensing data includes at least one of the following: information on the appearance of the target entity in front of the door, information on the distance change between the target entity and the door, and door lock interaction input signals. Specifically, by collecting at least one or more of the following in the pre-sensing step: information on the appearance of the target entity, information on the distance change between the target entity and the door, and door lock interaction input signals, it is possible to determine whether there is a genuine intention to enter the home from two dimensions: changes in spatial position and interactive behavior. This improves the accuracy of judging entry behavior trigger events and provides multi-source basic data for subsequent identification stages.

[0009] Furthermore, in the stage identification step, the behavioral stage identifiers include at least an initial stage identifier representing the initial state of entering the home, an approach stage identifier representing the process of the target subject approaching the door, a dwelling stage identifier representing the target subject maintaining a stable state in front of the door, an operation stage identifier representing the door lock interaction operation, and a completion stage identifier representing the completion of the home entry. Specifically, by subdividing the behavioral stage identifiers into initial stage identifiers, approach stage identifiers, dwelling stage identifiers, operation stage identifiers, and completion stage identifiers, the home entry behavior can be described in stages according to the actual physical behavior process. This helps to accurately reflect the complete process of a person from their appearance to the completion of entering the home, and provides clear stage boundaries for continuity verification and reliable judgment.

[0010] Furthermore, in the continuous verification step, the continuity verification is performed by comparing whether the arrangement order of adjacent behavior stage identifiers on the timeline conforms to a preset stage evolution rule. Specifically, by comparing whether the arrangement order of adjacent behavior stage identifiers on the timeline conforms to the preset stage evolution rule in the continuous verification step, it can be ensured that the entry behavior proceeds step by step according to reasonable behavioral logic, preventing premature entry into subsequent stages before the current stage is met, thereby improving the security of door lock control decisions.

[0011] Furthermore, in the credibility determination step, the credibility of the home visit behavior is determined based on the duration of each stage, the completeness of each stage, and the reasonableness of the transitions between stages in the home visit behavior state sequence. Specifically, by comprehensively analyzing the duration of each behavioral stage, the completeness of each stage, and the reasonableness of the transitions between stages in the home visit behavior state sequence during the credibility determination step, the authenticity and reasonableness of the home visit behavior can be judged from multiple dimensions. This allows the credibility determination result to reflect the overall characteristics of the home visit process, rather than a single instantaneous behavior.

[0012] Furthermore, in the decision generation step, a door lock control decision signal allowing unlocking is generated based on the credibility determination result of the entry behavior. Specifically, by determining whether to generate a door lock control decision signal allowing unlocking based on the credibility determination result in the decision generation step, the door lock control behavior is constrained by the credibility determination result, avoiding the execution of unlocking operations when the credibility of the entry behavior is insufficient.

[0013] Furthermore, in the continuous verification step, when it is detected that adjacent behavior stage identifiers do not satisfy the stage evolution relationship, a stage anomaly indication information is output to the decision generation step, so that the decision generation step generates a door lock control decision signal that prohibits door lock unlocking. Specifically, when the continuous verification step detects that adjacent behavior stage identifiers do not satisfy the stage evolution relationship, by outputting stage anomaly indication information to the decision generation step, the system can actively suppress door lock unlocking operations in the event of a behavior stage anomaly, thereby avoiding the risk of mis-locking due to abnormal behavior.

[0014] Furthermore, in the credibility determination step, the duration corresponding to at least one behavioral stage in the home entry behavior state sequence is compared with a preset time window, and the credibility determination result of the home entry behavior is corrected based on the comparison result. Specifically, by comparing the duration corresponding to at least one behavioral stage with a preset time window and correcting the credibility determination result of the home entry behavior based on the comparison result, the ability to identify abnormal home entry behavior can be further improved, making the credibility determination of home entry behavior closer to actual home entry scenarios.

[0015] Furthermore, in the decision generation step, when the credibility determination result of the entry behavior meets the preset credibility condition but the entry behavior state sequence has not reached the preset complete state, a door lock control decision signal restricting door unlocking is generated. Specifically, by generating a door lock control decision signal restricting door unlocking when the credibility determination result of the entry behavior meets the preset credibility condition but the entry behavior state sequence has not yet reached the preset complete state, premature unlocking before the entry behavior is fully completed can be avoided, thereby improving the rigor of door lock control.

[0016] Furthermore, after the door lock execution step, a state rollback step is included. When it is detected that the door lock control action is incomplete or interrupted, the entry behavior state sequence is rolled back to the previous state corresponding to the current behavior stage identifier. Specifically, by introducing a state rollback step after the door lock execution step, and rolling back the entry behavior state sequence to the previous state when it is detected that the door lock control action is incomplete or interrupted, the system can recover to a processable state in abnormal execution situations, improving the overall system robustness.

[0017] An intelligent entrance door processing system includes: The front sensing unit is used to collect entry sensing data in front of the smart entrance door and generate trigger information to indicate whether an entry behavior trigger event has occurred. A stage identification unit, connected to the pre-sensing unit, is used to divide the home entry process into stages based on the home entry sensing data after detecting the trigger information and generate a behavior stage identifier to characterize the home entry behavior process. A continuous verification unit, connected to the stage identification unit, is used to perform continuous verification on the sequential order between adjacent behavior stage identifiers based on the behavior stage identifier to generate a stage verification result. A state construction unit, connected to the continuous verification unit, is used to construct the behavior stage identifier into an in-home behavior state sequence in chronological order when the stage verification result indicates that the verification has passed. A credibility determination unit, connected to the state construction unit, is used to analyze the completeness and stage rationality of the home visit behavior based on the home visit behavior state sequence to generate a credibility determination result for the home visit behavior. The decision generation unit is connected to the stage identification unit and the credibility discrimination unit respectively, and is used to generate a door lock control decision signal based on the credibility judgment result of the entry behavior and in combination with the current corresponding behavior stage identifier. The door lock execution unit, connected to the decision generation unit, is used to drive the smart entrance door to perform the corresponding door lock action and output door lock execution status information when the door lock control decision signal indicates that door lock control operation is permitted. Specifically, the door lock execution status information includes door lock control action completion information or execution interruption information. This system divides the functions of the pre-sensing unit, stage identification unit, continuous verification unit, state construction unit, reliable discrimination unit, decision generation unit, and door lock execution unit into a signal interaction link, enabling the entry behavior to form a complete closed loop from perception, analysis to execution. It can implement processing logic consistent with the method at the hardware and control levels, thereby ensuring the feasibility of the method at the system level.

[0018] In one optional implementation, the entry sensing data collected by the front-end sensing unit includes at least one of the following: information on the appearance of the target object in front of the door, information on the distance change between the target object and the door, and door lock interaction input signals; the behavior stage identifiers generated by the stage identification unit include at least an initial stage identifier, an approach stage identifier, a dwell stage identifier, an operation stage identifier, and a completion stage identifier; the continuous verification unit generates a stage verification result by comparing whether the arrangement order of adjacent behavior stage identifiers on the time axis conforms to a preset stage evolution rule; and the trustworthy discrimination unit generates a result based on the stage duration, stage integrity, and the rationality of the stage transition. The system determines the credibility of the entry behavior and compares the duration of at least one behavior stage with a preset time window to correct the credibility determination result. The decision generation unit generates a door lock control decision signal that allows the door lock to unlock when the credibility determination result of the entry behavior meets the preset credibility conditions and the entry behavior state sequence reaches the preset complete state. When there is an abnormality in the stage or the entry behavior state sequence does not reach the preset complete state, it generates a door lock control decision signal that prohibits or restricts the door lock to unlock. The door lock execution unit outputs execution interruption information to trigger the rollback processing of the entry behavior state sequence when it detects that the door lock control action is not completed or is interrupted.

[0019] A smart front door includes: The door assembly includes a door panel and a door frame connection structure disposed on the door panel, which forms the basic load-bearing structure of the smart entrance door; A door lock assembly, disposed on the door panel, includes a bolt mechanism and a bolt drive mechanism, wherein the bolt mechanism is used to switch between a locked state and an unlocked state; A sensing installation component is disposed on the front side of the door body of the door assembly, and is used to install and fix an in-home sensing device for collecting in-home sensing data. The in-home sensing data is used to determine whether an in-home behavior trigger event has occurred. A processing control component, disposed within the internal space of the door assembly and electrically connected to both the sensing installation component and the door lock assembly, is used to generate behavioral stage identifiers characterizing the entry behavior process based on the entry sensing data, and to perform continuity verification on the sequence of adjacent behavioral stage identifiers to construct an entry behavior state sequence and generate an entry behavior credibility judgment result; and An execution linkage component, connected to the processing control component and the door lock component, is used to drive the latch drive mechanism to perform the corresponding door lock action when the processing control component generates a door lock control decision signal indicating permission to perform a door lock control operation. Specifically, this device integrates the door lock component, sensing installation component, processing control component, and execution linkage component onto the door body component, enabling entry behavior stage recognition and door lock execution control to be directly implemented in the specific mechanical and electromechanical structure. The sensing installation component ensures the location and direction of entry sensing data collection, the processing control component completes behavior stage recognition and decision generation, and the execution linkage component converts the door lock control decision signal into actual latch drive action, thereby realizing door lock control based on entry behavior stage recognition at the physical structure level.

[0020] Furthermore, the sensing installation assembly includes a mounting base disposed on the front side of the door assembly, a sensing bracket detachably connected to the mounting base, and an entry sensing device disposed on the sensing bracket. The sensing bracket is used to define the installation orientation of the entry sensing device to cover a preset entry area in front of the door.

[0021] Furthermore, the latch drive mechanism includes a drive motor, a transmission component, and a latch linkage connected to the transmission component. After receiving the door lock control decision signal, the drive motor drives the latch linkage to move through the transmission component, thereby pushing the latch mechanism to switch between a locked state and an unlocked state.

[0022] Furthermore, the execution linkage component includes a position detection component disposed on the latch mechanism. The position detection component is used to detect the actual position of the latch mechanism and feed back the door lock execution status information to the processing control component.

[0023] Furthermore, when the credibility determination result of the entry behavior indicates that the entry behavior is abnormal, the processing control component controls the execution linkage component to keep the latch mechanism in a locked state, so as to form a mechanical execution constraint on the door lock component.

[0024] Furthermore, the processing control component updates the entry behavior state sequence based on the door lock execution state information, and adjusts the entry behavior state corresponding to the behavior stage identifier when the door lock execution state information indicates that the door lock action has not been completed or has been interrupted.

[0025] The beneficial effects of this invention are: This solution transforms the handling of entry behavior from an instantaneous door lock control method based on a single trigger condition to a phased analysis and control decision-making method based on the entry behavior process by sequentially setting a pre-sensing step, a stage identification step, a continuous verification step, a state construction step, a trust judgment step, a decision generation step, and a door lock execution step in the intelligent entry door processing method.

[0026] The system collects entry-sensing data in front of the smart entrance door through a pre-sensing step and determines whether an entry behavior trigger event has occurred. This ensures the system only proceeds to subsequent processing when a valid entry behavior trigger event is detected, thereby reducing the impact of environmental changes or false triggers on door lock control. A stage identification step divides the entry process into stages and generates behavior stage identifiers to characterize the entry behavior progress. Combined with a continuous verification step, the system verifies the sequence of adjacent behavior stage identifiers, enabling it to identify unreasonable entry behaviors such as skipping, reversing, or abnormally repeating entry behavior stages, thus avoiding door lock control operations when the entry behavior process is abnormal.

[0027] Furthermore, the state construction step constructs an entry behavior state sequence by arranging the behavior stage identifiers in chronological order. In the trust judgment step, the completeness and stage rationality of the entry behavior are analyzed based on this entry behavior state sequence to generate an entry behavior trustworthiness judgment result. This ensures that the door lock control decision is based on the analysis of the overall entry behavior process. The decision generation step combines the entry behavior trustworthiness judgment result with the currently corresponding behavior stage identifier to generate a door lock control decision signal. In the door lock execution step, the smart door is driven to perform the corresponding door lock action and update the entry behavior state sequence based on the door lock control decision signal, thus forming a complete entry processing closed loop and improving the security and stability of the smart door in complex entry scenarios.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit the present invention. The connection relationships shown in the accompanying drawings are only for clear description and do not limit the connection method.

[0033] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0034] The inventors discovered that existing technologies, such as the solution in Document 1, typically treat entry behavior as an isolated event. That is, upon detecting password input or other unlocking triggers, the system directly enters the door lock control or image processing flow without modeling and verifying the continuous evolution of the entry behavior over time. This approach struggles to distinguish between normal and abnormal entry behaviors, such as abnormal entry sequence, abnormal dwell time at the door, or repeated interruptions in the operation. This can easily lead to premature door unlocking before the entry behavior is properly completed, posing potential security risks.

[0035] Furthermore, existing technologies lack a continuity verification mechanism for the sequential relationship between different stages of the entry process, and also lack technical means to constrain door lock control decisions based on the overall state of the entry process. In complex or abnormal entry scenarios, relying solely on a single trigger condition or partial information makes it difficult to achieve refined management of door lock control timing, and the system's robustness and security still have room for improvement.

[0036] Therefore, existing smart door technologies urgently need a new processing solution that can perform phased recognition and continuous analysis of entry behavior without relying solely on image optimization or single-trigger judgment, and generate door lock control decisions based on the overall process of entry behavior, in order to solve the problems of lack of overall constraints on the entry behavior process and the susceptibility of door lock control to abnormal behavior interference in existing technologies.

[0037] Therefore, such as Figure 1 and Figure 2As shown, this application provides a smart door processing method based on entry behavior stage recognition, including the following steps: Pre-entry sensing step: Collect entry sensing data in front of the smart entrance door to determine whether an entry behavior trigger event has occurred; Phase identification steps: After detecting the home entry behavior trigger event, the home entry process is divided into phases based on the home entry perception data, and a behavior phase identifier is generated to characterize the home entry behavior process. Continuous verification step: Based on the generated behavior stage identifier, the sequential order between adjacent behavior stage identifiers is continuously verified to determine whether the current home entry behavior meets the preset stage evolution relationship; State construction steps: If the continuity check passes, the behavior stage identifiers are constructed into a home visit behavior state sequence in chronological order; Credibility determination step: Analyze the completeness and stage rationality of the home visit behavior based on the home visit behavior state sequence to generate a credibility determination result for the home visit behavior; specifically, by comprehensively analyzing the continuity and completeness of the behavior stages based on the home visit behavior state sequence, the credibility determination result of the home visit behavior can reflect the overall rationality of the home visit process, rather than a single operation triggering condition. Decision generation steps: Generate a door lock control decision signal based on the credibility determination result of the entry behavior and the corresponding behavior stage identifier; Door lock execution steps: When the door lock control decision signal indicates that the door lock control operation is allowed, a door lock control command is output to drive the smart entrance door to perform the corresponding door lock action and update the entrance behavior state sequence to the entrance completed state.

[0038] This solution introduces a pre-sensing step, a stage identification step, a continuous verification step, a state construction step, a trust judgment step, a decision generation step, and a door lock execution step into the entry process of the smart entry door. This transforms the processing of entry behavior from a single trigger-based control to a staged judgment and decision control based on the behavior process, thereby effectively improving the security and stability of the entry process.

[0039] First, the system collects entry sensing data in front of the door through a pre-sensing step, and determines whether an entry behavior trigger event has occurred. This ensures that the system only enters the subsequent processing flow when a valid entry sign is detected, avoiding door lock control actions caused by irrelevant environmental changes or accidental triggers, thus reducing the probability of system misjudgment from the source.

[0040] Secondly, the home visit process is divided into stages through a stage identification step, and behavioral stage identifiers are generated to characterize the progress of the home visit behavior. This allows the home visit behavior to be described as a sequence of stages with a clear process state, rather than an isolated instantaneous event, providing basic data support for subsequent analysis of the overall rationality of the home visit behavior.

[0041] Based on this, the sequential order of adjacent behavior stage identifiers is continuously verified through continuous verification steps, enabling the system to determine whether the current entry behavior conforms to the preset stage evolution relationship. This effectively identifies unreasonable entry behaviors such as stage jumps, reverse order, or abnormal repetition, and avoids triggering door lock control operations when the entry process is abnormal.

[0042] Furthermore, through the state construction step, the behavior stage identifiers after continuity verification are constructed into a home entry behavior state sequence in chronological order, enabling the system to represent the evolution process of home entry behavior in the time dimension as a whole, rather than making judgments based on a single stage or single operation, thereby improving its adaptability to complex home entry scenarios.

[0043] By employing a trustworthy judgment step, the system analyzes the completeness and stage rationality of the entry behavior based on the entry behavior state sequence and generates an entry behavior trustworthiness judgment result. This enables the system to quantitatively judge the trustworthiness of entry behavior before door lock control, avoiding direct unlocking operations based solely on partial behaviors or single conditions, thus further improving entry security. Through a comprehensive analysis of the continuity and completeness of behavior stages based on the entry behavior state sequence, the entry behavior trustworthiness judgment result reflects the overall rationality of the entry process, rather than a single operation trigger condition.

[0044] Based on this, the decision generation step combines the credibility judgment result of the entry behavior with the current corresponding behavior stage identifier to generate a door lock control decision signal, so that door lock control is no longer a simple binary trigger, but a comprehensive decision-making process based on the behavior process state and credibility, thereby realizing refined constraints on the timing and conditions of door lock control.

[0045] Finally, when the door lock control decision signal indicates that the door lock control operation is allowed, the door lock execution step outputs a door lock control command and drives the smart entrance door to perform the corresponding door lock action. At the same time, the entrance behavior state sequence is updated to the entrance completion state, so that the door lock execution result can have a reverse effect on the entrance behavior state management, ensuring the complete closed loop of the entrance processing process.

[0046] In summary, this solution introduces behavioral stage identification, stage continuity verification, entry behavior state sequence, and a trust-based door lock decision mechanism, enabling smart entry doors to execute door lock control operations based on the overall process of entry behavior rather than a single trigger condition. This achieves effective constraint and security control of entry behavior without relying on complex image processing algorithms, demonstrating a clear structure, rigorous logic, and wide applicability.

[0047] In one exemplary implementation, the process for determining the credibility of a home visit can be performed as follows: After constructing the home visit behavior state sequence, the system first determines whether the sequence contains the expected behavior stages and checks whether each stage appears sequentially according to a preset stage evolution relationship to confirm the completeness of the home visit behavior at the stage level. Subsequently, the system analyzes the duration of at least one behavior stage in the home visit behavior state sequence and compares this duration with a preset time window to determine whether the behavior stage is within a reasonable time range. When the duration of a certain behavior stage significantly deviates from the time window, the system can adjust the home visit behavior credibility judgment result accordingly. Based on the above judgments, the system comprehensively considers the stage completeness, stage order rationality, and stage duration rationality of the home visit behavior state sequence to generate a home visit behavior credibility judgment result characterizing the credibility of the current home visit behavior. Those skilled in the art can configure or adjust the above judgment conditions according to actual application scenarios to achieve adaptation to different home visit scenarios.

[0048] Example 1 like Figure 3 As shown, this embodiment provides an intelligent entrance door processing system, which is used to perform phased identification and security judgment of the entrance behavior during the user's entrance process, and control the door lock of the intelligent entrance door to perform actions based on the judgment results.

[0049] The intelligent entrance door processing system described in this embodiment includes a front-end sensing unit, a stage identification unit, a continuous verification unit, a state construction unit, a reliable discrimination unit, a decision generation unit, and a door lock execution unit. The units interact with each other through data or signals to form a processing link for entrance behavior recognition and door lock control.

[0050] The front-end sensing unit is used to collect entry sensing data in front of the smart entrance door and generate trigger information based on the collected entry sensing data to indicate whether an entry behavior trigger event has occurred. In this embodiment, the entry sensing data may include at least one of the following: information on the detection of the presence of a target in front of the door, information on the change in distance between the target and the door, and door lock interaction input signals, but is not limited to these.

[0051] The stage identification unit is connected to the pre-sensing unit. After detecting the trigger information, it divides the home entry process into stages based on the home entry sensing data and generates a behavior stage identifier to characterize the home entry behavior process. The behavior stage identifier is used to distinguish different process states in the home entry process and serves as the basic input information for subsequent continuous verification, state construction, and door lock control decisions.

[0052] The continuous verification unit is connected to the stage identification unit and is used to perform continuity verification on the sequential order of adjacent behavior stage identifiers based on the behavior stage identifiers, thereby determining whether the current home visit behavior meets the preset stage evolution rules. In this embodiment, the stage evolution rules are used to limit the home visit behavior to proceed step by step in a preset process order, so as to avoid abnormal situations such as skipping, reversing, or repeating stages of the home visit behavior.

[0053] The state construction unit is connected to the continuous verification unit. When the continuous verification result indicates that the verification has passed, the behavior stage identifiers are constructed into a home visit behavior state sequence according to time order, which is used to represent the overall process state of the current home visit behavior. The home visit behavior state sequence reflects the continuous evolution of the home visit behavior in the time dimension.

[0054] The trustworthiness determination unit is connected to the state construction unit and is used to analyze the completeness and stage rationality of the home entry behavior based on the home entry behavior state sequence, and generate a trustworthiness determination result for the home entry behavior. In this embodiment, the trustworthiness determination unit can comprehensively consider factors such as the duration of each behavior stage in the home entry behavior state sequence, whether the stage is complete, and whether the stage transition is reasonable, to determine the trustworthiness of the home entry behavior.

[0055] The decision generation unit is connected to both the stage identification unit and the credibility judgment unit. It generates a door lock control decision signal based on the credibility judgment result of the entry behavior and the corresponding current behavior stage identifier. By simultaneously incorporating behavior stage information and credibility judgment results, it avoids executing door lock control actions based on only a single judgment condition.

[0056] The door lock execution unit is connected to the decision generation unit and is used to drive the smart entrance door to perform the corresponding door lock action when the door lock control decision signal indicates that the door lock control operation is allowed, and output the door lock execution status information to reflect the execution result of the door lock control action.

[0057] Example 2 Based on Example 1, this example further describes the system's handling methods for abnormal entry behavior and complex entry scenarios, in order to support the technical features of stage anomaly suppression, time window constraints, and state rollback mechanism.

[0058] In this embodiment, when the continuous verification unit performs continuity verification on adjacent behavior stage identifiers, if it detects that the current behavior stage identifier does not meet the preset stage evolution rules, it outputs stage anomaly indication information to the decision generation unit. After receiving the stage anomaly indication information, the decision generation unit generates a door lock control decision signal that prohibits door lock unlocking, thereby avoiding door lock unlocking operations when there is an anomaly in the entry behavior stage.

[0059] In this embodiment, when analyzing the sequence of in-home behavior states, the credibility determination unit can also compare the duration of at least one behavior stage with a preset time window and correct the credibility determination result of the in-home behavior based on the comparison result. For example, when the duration of a certain behavior stage deviates significantly from the preset time window, the credibility of the corresponding in-home behavior can be reduced even if other conditions are met.

[0060] Furthermore, in this embodiment, when the credibility determination result of the entry behavior meets the preset credibility condition but the entry behavior state sequence has not yet reached the preset complete state, the decision generation unit generates a door lock control decision signal to restrict door lock unlocking, thereby avoiding the situation where the door lock is unlocked before the entry behavior is fully completed.

[0061] During door lock operation, if the door lock execution unit detects that the door lock control action is incomplete or interrupted, it feeds back the corresponding execution interruption information to the state construction unit. Upon receiving the execution interruption information, the state construction unit reverts the entry behavior state sequence to the previous state corresponding to the current behavior stage identifier, so that the entry behavior can be re-identified and judged in subsequent stages.

[0062] Through the above methods, the intelligent entrance door processing system described in this embodiment can realize the phased recognition, continuous verification and credibility determination of entrance behavior in various entrance scenarios, and reasonably control the door lock execution actions based on the determination results, thereby improving entrance security and system stability.

[0063] Example 3 like Figure 4 As shown, this embodiment provides a smart entrance door, which is used to realize the phased recognition of entry behavior and door lock execution control at the physical structure level of the smart entrance door. Its overall structure is as follows: The smart entrance door described in this embodiment includes a door body component, a door lock component, a sensing installation component, a processing and control component, and an execution linkage component. Each component is integrated and arranged around the door body structure of the smart entrance door, and forms a complete smart entrance door through mechanical and electrical connections.

[0064] The door assembly includes a door panel and a door frame connection structure mounted on the door panel. The door panel is used to support the door lock assembly, the sensing installation assembly, and the processing control assembly. The door frame connection structure is used to install the door panel onto the door frame in an openable manner, thereby forming the basic load-bearing structure of the smart entrance door.

[0065] The door lock assembly is mounted on the door panel and includes a latch mechanism and a latch drive mechanism. The latch mechanism is used to switch between a locked state and an unlocked state, and the latch drive mechanism is used to drive the latch mechanism to perform the corresponding door lock action when a door lock control decision signal is received. In this embodiment, the latch drive mechanism may include a drive motor and a transmission component connected to the drive motor. The transmission component and the latch mechanism form a mechanical linkage relationship, but this is not a limitation.

[0066] The sensing installation component is located on the front side of the door assembly and is used to install and fix the in-home sensing device for collecting in-home sensing data. The sensing installation component is used to define the installation position and orientation of the in-home sensing device in front of the door, so that the collected in-home sensing data can cover a preset in-home area in front of the door. The in-home sensing data is used to determine whether an in-home behavior trigger event has occurred.

[0067] The processing and control component is located within the internal space of the door assembly and is electrically connected to both the sensing installation component and the door lock assembly. The processing and control component generates behavioral stage identifiers characterizing the entry behavior process based on entry sensing data, and performs continuity verification on the sequence of adjacent behavioral stage identifiers to construct an entry behavior state sequence and generate an entry behavior credibility judgment result. The processing and control component also outputs the door lock control decision signal to the execution linkage component after generating the decision signal.

[0068] The execution linkage component is connected to the processing control component and the door lock component. When the processing control component generates a door lock control decision signal indicating permission to perform a door lock control operation, it drives the latch drive mechanism to perform the corresponding door lock action. In this embodiment, the execution linkage component establishes an execution linkage relationship between the processing control component and the door lock component during door lock execution, thereby ensuring that the door lock action can be controlled based on the entry behavior stage identification results.

[0069] Through the above structural design, the smart entrance door described in this embodiment can introduce a processing and control mechanism based on the identification of the entry behavior stage while maintaining the stability of the traditional door body and door lock mechanical structure. This makes the execution actions of the door lock components subject to the overall state of the entry behavior process, thereby improving the security and reliability of the smart entrance door in complex entry scenarios.

[0070] In detail: The core idea of ​​this solution is to upgrade the traditional smart door control method based on single triggering or isolated operation to a phased recognition and overall judgment method based on the process of entering the home.

[0071] By modeling the continuous evolution of entry behavior over time, door lock control no longer depends solely on a single instantaneous operation, but rather on whether the entry behavior proceeds in a reasonable, continuous, and complete sequence of stages, thereby logically improving the security and stability of entry control.

[0072] To achieve the above objectives, this solution revolves around the overall processing chain of perception, identification, verification, modeling, judgment, decision-making, and execution. It introduces perception and judgment before the entry behavior occurs, introduces stage continuity constraints during the entry behavior process, and introduces a comprehensive credibility judgment mechanism before the door lock is executed, thereby constructing a closed-loop, rollback-capable, and anomaly-suppressible entry processing flow.

[0073] In this solution, the first step is to collect the entry sensing data in front of the smart entrance door through a front-end sensing mechanism.

[0074] The in-home sensing data may include one or more of the following: information on the appearance of a target in front of the door, information on changes in the distance between the target and the door, and door lock interaction input signals.

[0075] By analyzing the aforementioned in-home perception data, the system determines whether there are genuine in-home behavior trigger events. Only when a valid in-home behavior trigger event is detected will the subsequent in-home behavior processing flow begin, thereby avoiding interference with door lock control caused by environmental changes, false triggers, or non-in-home behaviors.

[0076] This mechanism ensures that all subsequent processing steps are based on a genuine intention to visit the home, and it is the starting point of the entire process.

[0077] After detecting a home visit trigger event, the system divides the home visit process into stages based on the collected home visit perception data and generates a behavior stage identifier to characterize the progress of the home visit behavior.

[0078] The behavior stage identifier is used to abstractly describe the process status of the home visit behavior in different time periods, so that the home visit behavior is no longer regarded as a single event, but as a behavior process composed of multiple consecutive stages.

[0079] In one embodiment, the behavior stage identifiers may include an initial stage identifier for characterizing the initial state of entering the home, an approach stage identifier for characterizing the process of the target subject approaching the door, a dwelling stage identifier for characterizing the target subject maintaining a stable state in front of the door, an operation stage identifier for characterizing the door lock interaction operation, and a completion stage identifier for characterizing the state of completing the entry into the home.

[0080] The above phased description provides a clear phased basis for subsequent phased continuity verification and overall analysis of door-to-door behavior.

[0081] After generating behavior stage identifiers, the system performs a continuity check on the order of adjacent behavior stage identifiers to determine whether the home visit behavior meets the preset stage evolution relationship.

[0082] The aforementioned stage evolution relationship is used to define the reasonable sequence of the home visit behavior on the timeline. For example, the target subject should appear first, then approach the door, then stop and operate, and finally complete the home visit.

[0083] When the system detects that adjacent behavior stage identifiers do not satisfy the stage evolution relationship, it determines that the current entry behavior has a stage anomaly and generates stage anomaly indication information. This stage anomaly indication information is used to suppress door lock unlocking operations in subsequent processing, thereby avoiding door lock actions when the behavior process is abnormal.

[0084] This continuity verification mechanism enables the system to proactively identify skipped, reversed, or abnormally repeated entry behaviors.

[0085] If the continuity check passes, the system will construct the behavior stage identifiers into a sequence of in-home behavior statuses in chronological order.

[0086] The sequence of home visit behavior states is used to characterize the evolution of home visit behavior over time as a whole, and is a structured description of the entire home visit behavior process.

[0087] By tracking the sequence of in-home behavior, the system can simultaneously grasp the stages of behavior that have occurred, the current stage, and the connections between these stages, providing a holistic perspective for subsequent credibility analysis.

[0088] After constructing the home visit behavior state sequence, the system analyzes the completeness and stage rationality of the home visit behavior based on the state sequence to generate a home visit behavior credibility judgment result.

[0089] In one implementation, the credibility determination can comprehensively consider the duration of each behavioral stage in the home visit behavior state sequence, whether the stage is complete, and whether the transition between stages is reasonable. For example, when the duration of a certain behavioral stage deviates significantly from a preset time window, the credibility of the home visit behavior can be corrected even if other stages meet the conditions.

[0090] Through the above methods, the credibility determination results of home visit behavior can reflect the overall characteristics of the home visit process, rather than a single operation or instantaneous signal.

[0091] After obtaining the credibility assessment result of the entry behavior, the system generates a door lock control decision signal by combining the corresponding behavior stage identifier.

[0092] When the credibility determination result of the entry behavior meets the preset credibility conditions and the entry behavior state sequence reaches the preset complete state, the system generates a door lock control decision signal that allows the door lock to be unlocked. When the credibility of the entry behavior is insufficient, there are abnormalities in the stage, or the entry behavior state sequence has not yet reached the preset complete state, the system generates a door lock control decision signal to restrict the door lock unlocking.

[0093] When the door lock control decision signal indicates that the door lock control operation is allowed, the system outputs a door lock control command to drive the smart entrance door to perform the corresponding door lock action, and updates the entrance behavior state sequence to the entrance completion state, thus forming a complete processing closed loop.

[0094] In one implementation, the system may also introduce a state rollback mechanism after the door lock control action is executed.

[0095] When the system detects that the door lock control action is incomplete or interrupted, it will roll back the entry behavior state sequence to the previous state corresponding to the current behavior stage identifier, so that the system can recover to a state that can continue to be processed in abnormal situations, thereby improving the robustness of the overall processing flow.

[0096] Through the above technical solutions, this solution introduces behavior stage identification, stage continuity verification, entry behavior state sequence construction, and credibility judgment mechanism based on the overall process in the entry control process, so that the door lock control is based on the analysis of the entire entry behavior process.

[0097] Compared to entry control methods that rely on a single trigger condition or a single operation, this solution can effectively identify abnormal entry behavior and prevent premature unlocking when the behavior is abnormal or not yet fully completed, thereby improving the security, stability and reliability of smart entry doors in complex entry scenarios.
