Description

Technical Field

[0001] The present invention relates to the technical field of access control management, and in particular to a dynamic access control system that quickly responds to emergency scenarios. Background Art

[0002] With the development of society, various emergencies occur frequently, such as fires, earthquakes, terrorist attacks, etc. In these emergency scenarios, traditional access control systems are often unable to quickly and effectively adjust access rights dynamically to meet the needs of emergency rescue and personnel evacuation.

[0003] Most existing access control systems are managed based on preset permission rules, which make it difficult to make quick changes in emergency scenarios. In the event of a fire, access to certain channels needs to be immediately opened to facilitate evacuation. However, due to the limitations of permission settings, the existing system may not be able to respond in time, resulting in obstructed evacuation. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides a dynamic access control system that quickly responds to emergency scenarios, which solves the problems of complex access control system permission adjustment process and slow response speed.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a dynamic access control system for rapid response to emergency scenarios, including: an emergency perception module, an emergency decision-making module, an authority adjustment module, a central control module, an execution and feedback module, an information notification module and a plan management module;

[0006] The emergency sensing module is used to monitor environmental changes in real time or receive external alarm signals;

[0007] The emergency decision module matches the emergency plan based on the data provided by the perception module or generates an access control authority adjustment strategy through an intelligent algorithm;

[0008] The authority adjustment module dynamically modifies the access control authority based on the adjustment strategy;

[0009] The execution and feedback module is responsible for synchronizing the permission adjustment to the access control device and collecting the execution feedback;

[0010] The emergency plan management module is used to preset, edit and manage various emergency plans;

[0011] The information notification module is used to push access control authority adjustment information and evacuation instructions.

[0012] Through the above technical solution: through layered architecture design, dynamic allocation and load balancing of emergency resources are realized, the central control module monitors the operating status of each module in real time, and the plan database supports version management and permission tracing, ensuring that the entire system is auditable and traceable.

[0013] Preferably, the emergency perception module includes an environment monitoring unit, a personnel monitoring unit and an external signal receiving unit. The environment monitoring unit is used to detect physical environment anomalies, the personnel monitoring unit is used to track personnel status and behavioral characteristics, and the external signal receiving unit is used to obtain cross-system emergency instructions.

[0014] Through the above technical solution: the environmental monitoring unit can identify secondary disaster risks, the personnel monitoring unit can analyze the aggregated risks through thermal maps, and the external signal receiving unit supports multi-national emergency code conversion to adapt to international scenario needs.

[0015] Preferably, the emergency decision-making module includes an event fusion analysis unit and a dynamic permission engine. The event fusion analysis unit adopts DS evidence theory to fuse multi-source data. The dynamic permission engine is used to generate a four-dimensional permission matrix. The emergency decision-making module can dynamically set different access control permission adjustment strategies based on event type and level.

[0016] Through the above technical solution: chain reactions are predicted through event correlation analysis, and the dynamic permission engine introduces an escape path planning algorithm to automatically generate the optimal access control opening sequence, reducing decision-making blind spots.

[0017] Preferably, the permission adjustment module includes a policy parsing unit, a temporary authorization unit and a conflict resolution unit. The policy parsing unit is used to convert the JSON instructions output by the emergency decision module into execution commands of the access control execution module. The temporary authorization unit is used to generate temporary credentials. The conflict resolution unit is used to resolve permission conflicts when multiple events occur concurrently. The permission adjustment module has permission backtracking and recovery functions, and can automatically restore the normal access control configuration after the emergency state ends.

[0018] Through the above technical solution: the temporary authorization unit supports the grading of authority timeliness, and the conflict resolution unit combines with the emergency plan priority library to automatically identify key rescue paths and forcibly retain authority channels.

[0019] Preferably, the execution and feedback module includes an access control controller, a guidance device group and a feedback collection unit. The access control controller automatically switches the working mode according to the authority instructions issued by the central control module and the event level. The guidance device group guides personnel to move. The feedback collection unit is used to monitor whether the equipment is not opened normally due to obstacles. The execution and feedback module can record the authority adjustment operation log, personnel passage records and abnormal event data.

[0020] Through the above technical solution: the access control controller has a built-in fault self-detection function, the guidance equipment group dynamically updates the instructions based on real-time changes in escape routes, and the feedback collection unit uses abnormal data cluster analysis to provide early warning of equipment aging or human damage risks.

[0021] Preferably, the plan management module includes a plan sandbox testing unit and an adaptive optimization unit. The plan sandbox testing unit uses digital twin technology to simulate the fire spread path in the three-dimensional model of the building. The adaptive optimization unit is used to optimize the buffer distance of the epidemic isolation area. The plan management module supports customization of multiple emergency plans for different building types, organizational structures or emergency events, and supports rapid switching.

[0022] Through the above technical solutions: the sandbox testing unit supports cross-plan collaborative drills, the adaptive optimization unit introduces the A / B testing mechanism, compares the execution effects of historical plans, and continuously iterates and optimizes the strategy library.

[0023] Preferably, the information notification module includes a hierarchical notification unit and a multimodal interaction unit. The hierarchical notification unit is used to classify disasters into levels, and the multimodal interaction unit is used for multi-terminal information interaction. The information notification module can simultaneously release information in multiple forms such as text messages, APP push, broadcast and electronic screen prompts.

[0024] Through the above technical solution: the hierarchical notification unit sets up an intelligent degradation mechanism, the multimodal interaction unit extracts key instructions through semantic analysis, and generates simplified voice prompts suitable for the elderly group.

[0025] Preferably, the communication networking module adopts a heterogeneous network fusion architecture, integrating triple transmission channels of 5G private network, power carrier communication and low-orbit satellite link. The communication networking module has a built-in adaptive routing selection algorithm, which automatically switches to the anti-interference spread spectrum communication mode when a fire is detected that causes the wired network to be interrupted, and performs differential incremental data synchronization after communication is restored.

[0026] Through the above technical solutions: supporting the narrowband Internet of Things low-power transmission backup channel, the adaptive routing algorithm introduces the quantum encryption protocol to prevent emergency instructions from being hijacked or tampered with, and ensure the security of key instruction transmission.

[0027] Preferably, the four-dimensional authority matrix includes four axial parameters: time dimension, space dimension, personnel attributes and equipment status. The time dimension sets a graded attenuation coefficient to realize the gradient release of authority during the golden period of evacuation. The space dimension establishes a three-dimensional partition authority mapping based on the BIM model. The personnel attribute dimension integrates iris recognition and wearable device dual biometric verification. The equipment status dimension associates the linkage locking mechanism of the fire sprinkler system and the access control electromagnetic lock.

[0028] Through the above technical solution: the time dimension is bound to the emergency plan stage mark, the personnel attribute dimension is integrated with the emergency plan role label, the equipment status dimension is integrated with the power supply status, and the access control power supply mode is automatically switched.

[0029] Preferably, the access control controller is equipped with an edge computing unit, which starts the autonomous decision-making mode when the central control module loses connection, and executes authority control by parsing the locally cached emergency plan. The edge computing unit is equipped with a supercapacitor emergency power supply, which maintains the core functions for at least 120 minutes after power failure, and uses a surface acoustic wave sensor to monitor the deformation of the door body in real time. When a door frame distortion of more than 5mm is detected, the electromagnetic locking device is automatically released.

[0030] Through the above technical solutions: the edge computing unit supports lightweight blockchain technology to ensure that local operation logs cannot be tampered with, the emergency power supply is designed with a low-power operation mode, and in extreme cases, the core function is extended to 180 minutes. The door deformation monitoring data is uploaded to the cloud for post-disaster building safety assessment.

[0031] The present invention provides a dynamic access control system that can quickly respond to emergency scenarios. It has the following beneficial effects:

[0032] 1. The present invention realizes the rapid identification and dynamic authority control of emergency events through the collaborative mechanism of multi-source perception and intelligent decision-making. The system integrates multi-dimensional monitoring data of the environment, personnel and external signals, combines intelligent algorithms to accurately determine the type and level of disasters, and dynamically generates access control authority adjustment strategies. Based on the time decay mechanism and spatial partition mapping of the four-dimensional authority matrix, the system can automatically adjust the access rules at different emergency stages, thereby significantly improving the timeliness of emergency response and the orderliness of personnel evacuation.

[0033] 2. The present invention ensures the stable operation and autonomous decision-making ability of the system in extreme scenarios through the redundant design of heterogeneous communication and edge computing. The system adopts a multi-channel integrated communication architecture and automatically switches to anti-interference mode when the network is interrupted to ensure the continuity of command transmission. The access control controller has a built-in edge computing unit and emergency power supply. When the network or power is disconnected, it can still maintain core functions based on local plans, monitor the door status in real time and trigger the emergency unlocking mechanism, effectively avoiding the single point failure problem caused by the traditional system's reliance on centralized control, and significantly enhancing the system's environmental adaptability and disaster recovery capabilities.

[0034] 3. The present invention improves the scientific nature and execution efficiency of emergency management through plan simulation optimization and multimodal information collaboration, uses digital twin technology to dynamically deduce the building environment and disaster evolution, optimizes the rationality and operability of emergency plans, and simultaneously pushes information through multiple terminals to accurately convey evacuation instructions to personnel in different roles. The backtracking function quickly restores the normal configuration after the emergency is over, reducing the lag and operational risks of manual intervention. The full-process closed-loop management mechanism realizes integrated intelligent control from early warning, response to recovery, and comprehensively improves the level of safety protection in emergency scenarios.
