Description

TECHNICAL FIELD

[0001] The application relates to the technical field of intelligent access control, and in particular to an intelligent access control emergency unlocking system for bidirectional authentication unlocking. BACKGROUND

[0002] In modern intelligent access control systems, the bidirectional authentication unlocking method has become one of the core technologies for improving security. Bidirectional authentication unlocking ensures the double security of identity verification, greatly enhances the security of the access control system, and prevents the intrusion of illegal personnel. Analyzing the bidirectional authentication unlocking method of the intelligent access control system helps to improve the fault tolerance and flexibility of the access control system, especially in large buildings, enterprises or important facilities, security and usability cannot be ignored.

[0003] In the bidirectional authentication unlocking process, the intelligent access control emergency unlocking system goes through detailed steps and multiple verification links from user identity input, unlocking request generation to final execution of unlocking operation. Specifically, first, the user inputs an identity identifier or uses biometric identification for identity verification, and the intelligent lock generates unlocking operation information and sends it to the lock server. The lock server transmits the information to the infrastructure platform and displays a two-dimensional code to the user. The user scans the two-dimensional code through the mobile terminal and performs identity authentication, and generates a digital signature and sends it back to the infrastructure platform after verification. The platform verifies the signature and sends an unlocking instruction to the lock server, and the intelligent lock executes the unlocking operation. In case of emergency, if the user cannot unlock through regular identity authentication, the system can perform unlocking operation through emergency methods (such as administrator intervention, remote control, etc.), but still needs to perform identity verification and digital signature verification to ensure the security and anti-fraud of the operation. Through multiple identity authentication and digital signature, the intelligent access control emergency unlocking system can effectively ensure the security of the unlocking operation and provide reliable emergency unlocking response.

[0004] For example, the unlocking method and intelligent access control system disclosed in Chinese patent application No. CN118155318A includes: the intelligent lock generates unlocking operation information based on the user input identity identifier, sends the unlocking operation information to the infrastructure platform through the lock server, the infrastructure platform stores the unlocking operation information and sends a query parameter to the lock server, the lock server generates a two-dimensional code based on the query parameter, and the intelligent lock displays the two-dimensional code; the mobile terminal scans the two-dimensional code, the first application sends a data acquisition request to the infrastructure platform, performs identity authentication based on the unlocking operation information sent by the infrastructure platform, and if the identity authentication is passed, sends a third message to the infrastructure platform, the third message containing the received unlocking operation information and a first digital signature; the infrastructure platform verifies the first digital signature, and if the verification is passed, the intelligent lock performs the unlocking operation.

[0005] For example, the Chinese invention patent with publication number CN112907800B discloses a CTID intelligent access control unlocking method and system, which includes the following steps: S10, the Bluetooth module of the CTID intelligent access control is initialized to create UUID and Bluetooth name; S20, the mobile phone sends personal information to the server for verification, receives the returned verification result and authorization information; S30, the mobile phone searches and connects the CTID intelligent access control based on the authorization information and Bluetooth name, and obtains the UUID; S40, the mobile phone encapsulates the verification result and authorization information into an unlocking instruction, and sends the unlocking instruction to the CTID intelligent access control based on the UUID; S50, the CTID intelligent access control parses and verifies the received unlocking instruction to obtain the verification result and authorization information, executes the unlocking operation based on the verification result and authorization information, and sends the execution result to the mobile phone based on the UUID; S60, the mobile phone parses the received execution result and sends it to the server.

[0006] The above technology at least has the following technical problems: Most of the intelligent access control systems rely on network communication between the cloud platform, lock server and infrastructure platform to transmit authentication information and execute the unlocking operation. In high-security and high-traffic environments such as banks and telecommunications machine rooms, many intelligent access control systems rely on centralized authentication servers to complete identity verification. If these servers cannot withstand too many concurrent requests in a high-traffic environment, they may fail. At this time, the system not only cannot respond to the unlocking request, but also may cause the entire authentication process to be interrupted, thereby directly affecting the execution of the unlocking operation, so that the system cannot complete the authentication process or the unlocking instruction.

[0007] In addition, although two-way authentication and multiple identity verification improve security, the authentication process involves multiple steps, which increases the complexity of user operations, reduces unlocking efficiency, and affects system reliability. SUMMARY

[0008] To solve the technical problem of low emergency unlocking efficiency of intelligent access control in the prior art, the embodiments of the present application provide an intelligent access control emergency unlocking system for two-way authentication unlocking, and the technical solution is as follows: The application discloses an emergency unlocking system of an intelligent access control for bidirectional authentication unlocking, and relates to the technical field of access control.

[0009] The technical scheme provided by the embodiments of the application has at least the following beneficial effects: 1. In an intelligent access control system, single direction authentication (such as only entry authentication or only exit authentication) may introduce security risks or availability problems in the case of network anomalies, node switching, communication delays or blockages. The present invention, through the entry and exit dual authentication mechanism and the emergency unlocking adjustment mechanism, aims to balance security and availability, ensuring that the unlocking can be completed as safely as possible when the network state fluctuates, while reducing the risk of denial of service or unlocking failure caused by misjudgment, retry, path switching, etc. Specifically, the entry and exit authentication mechanism selection module determines whether to trigger the entry and exit authentication mechanism selection based on the obtained user input authentication password. Compared with traditional access control systems, the entry and exit dual authentication mechanism can provide more choices and higher authentication accuracy in different scenarios, avoiding the limitations of single authentication mode. At the same time, the mechanism selection of different paths allows the subsequent authentication process to be optimized to better balance user experience and security protection. Because the direction strategy is clear, the subsequent process will not confuse the entry and exit logic, reducing logical errors. After the entry authentication mechanism is triggered, the system obtains the user's entry authentication information and transmits it to the lock server. During this process, the system monitors the transmission stability and analyzes the network status during the authentication information transmission process. If the network status is not good, the system will adjust the transmission path according to the transmission decision result to optimize the transmission stability of the information and avoid the impact of frequent path switching on the authentication process. By monitoring the transmission stability of the authentication information in real time, it ensures that the authentication can be completed effectively in an unstable network environment. At the same time, determining whether to trigger the authentication mechanism adjustment helps to maintain high reliability in the case of network fluctuations or interference, thereby improving the response speed and stability of the access control system and avoiding authentication failures due to network problems. Compared with traditional access control systems that rely on fixed transmission paths, the dynamic path adjustment mechanism of the entry authentication mechanism trigger module significantly improves the adaptability and stability of the system, which can automatically optimize the transmission path according to the actual network environment, reducing authentication failures or delay problems caused by network instability. When the exit authentication mechanism is selected, the system obtains the user's exit authentication information and transmits it, while obtaining the transmission decision result of the authentication information. According to the entry and exit matching dual authentication mode, the system verifies whether the user's identity meets the exit requirements. If the verification is passed, the exit unlocking instruction is sent, otherwise the unlocking is refused. Through the dual authentication mechanism, the exit authentication mechanism trigger module can more accurately verify the user's entry and exit permissions, effectively preventing identity forgery and illegal access. Traditional systems mostly use single direction authentication, which is vulnerable to identity spoofing risks. In contrast, the present invention ensures the rigor of identity verification through dual authentication, greatly improving the security of the access control system and reducing the risk of system being attacked or misoperated by external attacks. When the entry and exit authentication mechanism is triggered, the system will perform a reliability detection of the access control unlocking linkage to ensure the accurate execution of the unlocking instruction.Many traditional access control systems do not carry out subsequent linkage detection after issuing the unlocking instruction, lack feedback closed-loop verification, and the access control unlocking linkage detection module provides real-time monitoring and self-adaptive adjustment capability for the whole interaction link of unlocking.

[0010] 2、By comparing the user input authentication information with the stored authentication password, it is judged whether the access authentication mechanism selection is triggered, when the match is successful, the system triggers the user direction selection prompt to determine whether the user is entering or leaving; if the input is wrong, the retry prompt for a certain number of times is performed; if the direction confirmation is not made within the set time, the input information is reacquired. Through the comparison of user authentication information and the combination of time constraint logic, intelligent identification and response control of the access direction request are realized. It not only prevents false triggering, but also improves the authentication interaction efficiency and reduces the invalid occupation of system resources. When it is determined that the user has an entry request, the system collects the user's face recognition information and fingerprint recognition information as the entry authentication information, and transmits it to the lock server. The system tracks the authentication data transmission process, acquires the authentication information transmission tracking quantity containing the sending and receiving check value and timestamp, and judges the transmission stability accordingly. The traditional access control system lacks a stability detection mechanism in the biological recognition information transmission process, and is prone to authentication failure in a weak network environment. The present application introduces a transmission tracking and delay monitoring mechanism, so that the system has the ability of "network self-awareness", and can dynamically adjust the authentication strategy according to the transmission state, improve the system stability and fault tolerance. Through multi-dimensional tracking of the entry authentication information, the present application can monitor whether the authentication process is reliable in real time, and timely find data anomalies or delay problems, so as to ensure the accuracy and safety of the lock opening decision. On this basis, the link stability is judged by the path hop count and change frequency, so that the system can quickly enter the emergency mode when instability is detected, greatly improving the reliability in complex network environment. In addition, the traditional system directly interrupts the authentication or forces to enter the mechanical authentication mode when the network is abnormal, and lacks a dynamic optimization mechanism. The present application can balance network fluctuations and authentication stability by optimizing the switching time, thereby improving the fault tolerance of the system. Further, when it is determined that the user has a leaving request, the leaving authentication transmission judgment result is acquired and the entry and exit matching bidirectional authentication is performed. The safety of the leaving authentication is improved through delay and check double judgment to prevent data forgery and delay attack. When the leaving authentication is abnormal, it can automatically switch to the mechanical authentication mode to ensure the availability of the access in emergency. At the same time, the entry and exit matching mechanism ensures that only the legal entry user can perform the leaving lock opening operation, eliminating security risks such as fake leaving authentication and replay attack, and realizing the entry and exit closed loop control. In addition, the existing access control system adopts independent entry and exit verification process and lacks matching logic. The present application realizes entry and exit information matching and bidirectional verification, strengthens security constraints, and improves the system protection level. Through the multi-level authentication mechanism and intelligent adjustment strategy, the access control system can operate stably in various complex environments. Compared with the prior art, the present system not only has a significant improvement in authentication accuracy, but also greatly enhances the fault tolerance and adaptability of the system through dynamic path adjustment, network state monitoring and intelligent switching mechanism.

[0011] 3、By combining the failure rates of electronic and mechanical unlocking, the reliability of the access control system linkage is comprehensively evaluated, which can effectively reflect the system performance, and a time dimension attenuation factor is further introduced to consider the system degradation over time, improving the reliability prediction of the system in long-term use. Electronic unlocking may fail due to dependence on communication, algorithm, hardware, etc.; mechanical unlocking reflects the reliability of physical mechanisms or mechanical structures. The failure rates of the two are coupled and evaluated, and a time attenuation correction is introduced to obtain a more realistic and dynamic reliability index. In the prior art, the emergency response strategy is often triggered only after a clear failure; the present application can start adjustment in advance when the reliability index falls below the threshold, with early warning adjustment capability. At the same time, the traditional system often uses a static threshold or empirical value to judge the unlocking reliability, without considering the influence of equipment, environment, and wear over time, and the present application introduces a dynamic model through a time dimension attenuation factor, making the reliability evaluation more in line with the actual long-term running state. When the system judges that the unlocking linkage reliability is declining, the emergency response mechanism automatically adjusts the retry number, authentication timeout time, mechanical maintenance period, detection trigger period, and other strategy parameters according to the current evaluation value. In this way, the system can give more retry opportunities, extend the waiting time, and strengthen mechanical inspection in weak environments to improve the unlocking success rate and prevent service interruption caused by rigid strategy. The system simultaneously collects feedback data for reliability reevaluation in the next cycle, forming a self-adaptive closed loop. Traditional access control or lock systems mostly use fixed retry numbers and fixed timeout times, which often perform poorly when the operating environment changes (such as network fluctuations, weak signal environment, mechanical aging), and the present application can be flexibly adjusted according to the reliability measurement results, improving adaptability and forming a closed-loop self-adjusting mechanism to enable the access control system to dynamically optimize its parameters as the environment, wear, network status, and failure rate change, improving long-term stability and reliability. BRIEF DESCRIPTION OF DRAWINGS

[0012] In order to more clearly illustrate the technical solutions in the embodiments of the present application, the drawings needed in the embodiment description will be briefly introduced. Obviously, the drawings in the following description are only some embodiments of the present application, and other drawings can be obtained by those skilled in the art without creative labor.

[0013] Figure 1 The structural schematic diagram of the intelligent access control emergency unlocking system for bidirectional authentication unlocking provided by the embodiment of the present application; Figure 2 The in-door authentication mechanism trigger flowchart of the intelligent access control emergency unlocking system for bidirectional authentication unlocking provided by the embodiment of the present application; Figure 3The flow chart of the access control unlocking linkage reliability detection of the intelligent access control emergency unlocking system for bidirectional authentication unlocking is provided for the embodiments of the application. DETAILED DESCRIPTION

[0014] The technical solutions in the application will be described below with reference to the drawings.

[0015] To make the technical problems, technical solutions and advantages of the application clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0016] In high-security places such as telecom machine rooms, intelligent access control systems usually rely on network communication between cloud authentication servers and lock control hosts to transmit bidirectional authentication information. When network communication is abnormal (such as delay, packet loss or server downtime), the access control host cannot receive authentication confirmation instructions in real time, so that the electronic lock cannot execute the unlocking action. Even if the system has multiple authentication mechanisms, its authentication link is still limited by network response delay, affecting the unlocking efficiency in high-concurrency access or emergency evacuation situations. In addition, the mechanical emergency unlocking in the existing system is designed independently of the electronic control module, and lacks linkage logic based on authentication status, resulting in a delay in response of the mechanical emergency passage or failure to determine the legal authorized identity when electronic authentication fails, thereby affecting the reliability and security of the access control system.

[0017] Specifically, the mechanical structure of the intelligent access control unlocking device ensures that each component can work cooperatively through a series of precise connection methods and transmission mechanisms to achieve a smooth unlocking and locking process. Specifically, the lock shell, as an external frame, is usually connected with the door body through bolts, welding or other fastening methods to ensure the stability of the entire lock device. The lock shell is provided with a sliding groove or a guide groove, and the internal structure (such as the main lock tongue and the fork) is guided and fixed through these grooves.

[0018] The handle transmission structure is connected with the main lock tongue structure through a transmission rod. When the user operates the handle, the transmission rod drives the lock tongue to move. The transmission structure inside usually contains a gear or a spring mechanism to realize flexible unlocking action. The rotation of the handle is transmitted to the lock tongue through the fork pin, ensuring that the positioning and movement of the lock tongue can be synchronized with the rotation action of the handle.

[0019] The inner and outer handle yokes are connected to the main lock tongue structure through pins and are located at both ends of the lock. The yoke is operated by the external handle or the internal operation to convert the rotary motion into linear motion, pushing the main lock tongue to unlock or lock. At the contact point between the yoke and the main lock tongue, there is usually a spring or bearing system to provide the necessary return force or resistance, ensuring the smoothness and stability of the yoke operation. The yoke pin is tightly connected with the yoke through the hole slot, playing a role in transmitting torque. The design of the pin ensures that the rotation process of the yoke will not be stuck or misaligned, thereby ensuring the accurate movement of the lock tongue. The elastic positioning mechanism usually uses springs or other flexible materials to fix the yoke in a certain position, preventing position deviation caused by external interference and ensuring the stability of the lock.

[0020] In addition, the safety twist linkage mechanism is connected to the main lock tongue through a rotating shaft and usually controls its action through gears, cams or screw linkages. When additional security is needed, the safety linkage mechanism will lock the lock tongue, and only after correct identity verification can the linkage be released, thereby preventing illegal unlocking. This mechanism is linked to other main components through mechanical transmission, ensuring that when an abnormal unlocking attempt is encountered, the protection mechanism can be automatically triggered, increasing the security of the lock. These components form a coordinated system through precise mechanical linkage and reasonable structural design, enabling the entire intelligent access control unlocking device to operate efficiently while maintaining high stability and security.

[0021] The access control system includes electronic and mechanical components. The mechanical lock may malfunction after long-term use, causing the lock to fail to operate normally. The electronic unlocking part may be affected by network, transmission delay and other factors, causing authentication failure. Effective monitoring and prediction of these failures can effectively intervene before the failure occurs. Figure 1 As shown in FIG. 1, the structure schematic diagram of the intelligent access control emergency unlocking system for bidirectional authentication unlocking provided by the embodiment of the present application, referring to Figure 1 The system includes an entry and exit authentication mechanism selection module, an entry authentication mechanism triggering module, an exit authentication mechanism triggering module and an access control unlocking linkage detection module.

[0022] Specifically, the access authentication mechanism selection module is configured to determine whether to trigger access authentication mechanism selection based on the acquired user input authentication password. The access authentication mechanism includes an access authentication mechanism for implementing access authentication to determine whether to send an access unlocking instruction, and an exit authentication mechanism for implementing exit authentication to determine whether to send an exit unlocking instruction. By optimizing the flexibility, security and efficiency of user authentication, the access control system ensures stable operation in different environments. By providing clear operation prompts, fault tolerance mechanisms, time management and feedback mechanisms, the system can not only meet the different needs of users, but also improve the convenience and efficiency of authentication while ensuring security. This design makes the access control system more intelligent and meets the modern demand for efficient, accurate and secure systems.

[0023] The specific process is as follows: First, the acquired user input authentication password is compared with the stored authentication password. It should be noted that the authentication password is stored in the intelligent access control emergency unlocking database. The intelligent access control emergency unlocking database is a database created for the intelligent access control emergency unlocking system designed for two-way access authentication unlocking. The database stores various setting values and mapping sets necessary for the system to run, such as authentication passwords. The initial setting of these setting values is not randomly specified. Technical personnel can manually set, adjust or fine-tune them at any time based on the specific performance of the system in actual testing, to ensure that the system can be continuously optimized to achieve the best working state.

[0024] If the user input authentication password is the same as the stored authentication password, the selection prompt is triggered to determine the user's access request. Otherwise, an authentication password verification retry prompt for setting the number of times of inputting the authentication password is sent.

[0025] If it is determined that the user has an access request within the set request determination time, the access authentication mechanism is triggered. If it is determined that the user has an exit request, the exit authentication mechanism is triggered. If there is no request within the set request determination time, a request acquisition failure prompt is sent, and the user input authentication password is reacquired.

[0026] By connecting input verification, intent selection and trigger authentication mechanism into a clear logical line, the system can have a clear processing strategy and feedback when facing various abnormal situations (mistaken input, delay, no response, malicious request).

[0027] The in-door authentication mechanism triggering module is configured to, if the in-door authentication mechanism is triggered, transmit the acquired in-door authentication information to the lock server and perform transmission stability monitoring to acquire an authentication information transmission judgment result for judging network status and authentication information availability, so as to judge whether to trigger authentication mechanism adjustment for avoiding frequent switching of path transmission nodes affecting in-door authentication information transmission. In general, the module makes the in-door authentication link not only a static "transmission of authentication and waiting for result", but also an intelligent subsystem with communication quality sensing and self-adaptive capability, effectively improving the resistance of the system to unstable networks, interference, link faults and other problems in actual deployment environment.

[0028] As shown in Figure 2 The in-door authentication mechanism triggering flowchart of the intelligent access control emergency unlocking system for in-out two-way authentication unlocking provided by the embodiment of the application is shown in FIG. 2. The corresponding logic is as follows: the acquired in-door authentication information is transmitted to the lock server and an authentication information transmission tracking quantity is acquired, it is judged whether the lock server receives the authentication data packet, if not, the authentication information transmission judgment result is authentication information transmission invalid, if yes, it is judged whether the authentication data delay response degree is within the delay response control interval, if yes, authentication data packet accuracy verification is performed, if not, authentication data transmission network status judgment is performed, and only when the authentication data delay response degree is within the delay response control interval and the authentication data verification result is verification passed, the authentication information transmission judgment result is authentication information transmission valid, transmission stability monitoring is continuously performed, otherwise, the authentication information transmission judgment result is authentication information transmission invalid, and authentication mechanism adjustment is triggered. Referring to Figure 2 , the in-door authentication mechanism is triggered, and the specific steps are as follows: M1, in-door authentication information for realizing user biological recognition verification in the in-door unlocking process is acquired through a camera and a fingerprint collection sensor, the in-door authentication information includes in-door face recognition information for realizing user face recognition verification in the in-door process and in-door fingerprint recognition information for realizing user fingerprint recognition verification in the in-door process, the in-door face recognition information is a face image, and the in-door fingerprint recognition information is a fingerprint image; the face and fingerprint recognition information provides two high-security verification modes, ensures that only a legal user can pass the authentication, and greatly enhances the security of the access control system.

[0029] M2, the in-door authentication information is transmitted to the lock server and an authentication information transmission tracking quantity for reflecting in-door authentication information transmission stability is acquired through a network monitoring tool, the authentication information transmission tracking quantity includes an authentication data packet sending verification value, an authentication data packet receiving verification value, an authentication data packet sending timestamp and an authentication data packet receiving timestamp.

[0030] M3, transmits the authentication information transmission judgment result according to the obtained authentication information transmission tracking value, the authentication information transmission judgment result, and the specific acquisition method is: M31, in the set time interval, the lock server is queried by the log query tool to determine whether the authentication data packet is received, if not, the authentication information transmission judgment result is obtained as authentication information transmission invalid, if yes, the authentication data delay response degree reflecting the authentication data packet transmission delay is obtained according to the authentication data packet sending timestamp and the authentication data packet receiving timestamp, the authentication data delay response degree is the difference between the authentication data packet receiving timestamp and the authentication data packet sending timestamp, and the obtained authentication data delay response degree is compared with the stored delay response control interval.

[0031] M32, if the authentication data delay response degree is in the delay response control interval, the authentication data packet accuracy verification is carried out, specifically: the authentication data packet sending verification value and the authentication data packet receiving verification value are compared, if the two are the same, that is, the authentication data packet sending verification value is equal to the authentication data packet receiving verification value, the authentication data verification result reflecting the authentication data packet transmission accuracy is recorded as verification passed, otherwise, the authentication data verification result is recorded as verification failed.

[0032] M33, if the authentication data delay response degree is not in the delay response control interval, the authentication data transmission network state judgment is carried out, and the specific process is as follows: M331, in the authentication data transmission set interval, the authentication data packet is subjected to route path change detection, so as to obtain the route path tracking value reflecting the network link stability of the authentication data packet in the transmission process by the path detection tool, the route path tracking value includes the path hop count and the path change frequency.

[0033] M332, it is judged whether the path hop count in the authentication data transmission set interval is greater than the path hop count set maximum value, if yes, it is judged that the authentication data transmission network is abnormal, and the instruction of switching to the mechanical authentication mode is sent.

[0034] M333, otherwise, inputting the path hop number into a transmission setting adjustment interval mapping set to output an authentication data transmission adjustment interval, setting the next authentication data transmission setting interval according to the output authentication data transmission adjustment interval, i.e. setting the next authentication data transmission setting interval as the authentication data transmission adjustment interval, and obtaining the path change frequency within the next authentication data transmission setting interval; the transmission setting adjustment interval mapping set is obtained by pre-training using historical path hop numbers and authentication data transmission adjustment intervals set by professionals according to experience rules, and is used to describe the mapping relationship between the path hop number and the authentication data transmission adjustment interval; when the network quality is poor, the detection interval can be lengthened to reduce the detection overhead and avoid the additional load on the network caused by frequent detection; when the network quality is good, the detection interval can be shortened to improve the response sensitivity; this adaptive control balances the monitoring frequency and resource overhead.

[0035] M334, if the path change frequency within the next authentication data transmission setting interval is greater than the path change frequency setting maximum value, determining that the authentication data transmission network is abnormal, otherwise, determining that the authentication data transmission network is qualified, and triggering the authentication mechanism adjustment.

[0036] M34, when and only when the authentication data delay response degree is within the delay response control interval and the authentication data verification result is verification passed, obtaining the authentication information transmission judgment result as authentication information transmission valid, and continuing to perform transmission stability monitoring, otherwise, obtaining the authentication information transmission judgment result as authentication information transmission invalid, and triggering the authentication mechanism adjustment.

[0037] It should be noted that triggering the authentication mechanism adjustment has the following specific steps: If the authentication data delay response degree is within the delay response control interval, inputting the authentication data delay response degree into a switch suppression time adjustment mapping table to correspondingly output a switch suppression time threshold, setting the initial switch suppression time threshold according to the output switch suppression time adjustment threshold, i.e. setting the initial switch suppression time threshold as the switch suppression time adjustment threshold, and the switch suppression time threshold is the maximum time window length for limiting the switch of the path transmission node in the path switch process; the switch suppression time adjustment mapping table is obtained by pre-training using historical authentication data delay response degrees and switch suppression time thresholds set by professionals according to experience rules, and is used to describe the mapping relationship between the authentication data delay response degree and the switch suppression time threshold; by adjusting the switch suppression time threshold according to the authentication data delay response degree, the system can effectively manage the time window in the path switch process, and avoid excessive delay caused by frequent path switching. This mechanism can ensure the smoothness of the authentication process by limiting the maximum time window of path switching, and avoid system instability or authentication delay caused by frequent node switching.

[0038] If the authentication data delay response degree is not within the delay response control interval, the path hop count and the path change frequency within the next authentication data transmission setting interval are arithmetically averaged, and the result is input into the switch suppression time optimization mapping table, wherein the path hop count and the path change frequency have been de-unitized before arithmetical averaging, and the corresponding switch suppression time optimization threshold is output, and the initial switch suppression time threshold is set according to the output switch suppression time optimization threshold, that is, the initial switch suppression time threshold is set as the switch suppression time optimization threshold; the switch suppression time optimization mapping table is obtained by pre-training using the result of arithmetically averaging the path hop count and the path change frequency within the next authentication data transmission setting interval, and the switch suppression time optimization threshold set by professionals according to experience rules, and is used to describe the mapping relationship between the result of arithmetically averaging the path hop count and the path change frequency within the next authentication data transmission setting interval and the switch suppression time optimization threshold.

[0039] Path switching consumes certain network resources and bandwidth, and frequent path switching may cause excessive network load and even network congestion. By reasonably setting the switch suppression time threshold, the system can reduce unnecessary path switching, avoid waste of network resources, and improve overall network efficiency.

[0040] The design of triggering authentication mechanism adjustment effectively improves the stability, flexibility and fault tolerance of the access control system in complex network environment through comprehensive adjustment of authentication data delay response degree, path hop count and path change frequency. The system can automatically optimize the authentication process according to network delay, path change and other information, ensure the timeliness and accuracy of authentication operation, reduce the risk of authentication failure caused by network fluctuations, and thus improve the reliability and security of the access control system. This adaptive and dynamic adjustment mechanism enables the access control system to efficiently cope with different network environments and ensures long-term stable operation of the system.

[0041] The out-door authentication mechanism triggering module is configured to, if the out-door authentication mechanism is triggered, perform out-door authentication information transmission to obtain an out-door authentication transmission determination result, and perform in-out matching bidirectional authentication to determine whether to send a lock opening instruction. By performing out-door authentication information transmission and in-out matching bidirectional authentication, only users who have passed strict verification can open the lock. This bidirectional authentication mechanism improves the security of the system and prevents unauthorized personnel from accidentally or maliciously opening the lock when going out, thereby improving the ability to prevent identity fraud. The introduction of this module not only verifies the identity of the out-door user, but also further confirms the user's identity through matching of the in-door authentication, thereby increasing the security level of the authentication and ensuring that the access control operation is only performed under the authorization of the identity confirmation.

[0042] As a further solution, the out-door authentication mechanism is triggered, and the specific steps are as follows: The obtained exit authentication information is transmitted to a lock server to obtain an exit authentication transmission determination result, and the exit authentication information includes exit face recognition information used for face recognition verification in an exit process and exit fingerprint recognition information used for fingerprint recognition verification in the exit process.

[0043] The exit authentication transmission determination result is obtained, and specifically, The lock server is queried by a log query tool to determine whether the exit authentication data packet is received within an exit authentication interval, and if not, an instruction to switch to a mechanical authentication mode is sent; if yes, an exit delay response degree reflecting a transmission delay of the exit authentication data packet is obtained, and the exit delay response degree is a difference between an exit authentication data packet receiving timestamp and an exit authentication data packet sending timestamp.

[0044] If the exit delay response degree is not within the exit delay response interval, the exit authentication transmission determination result is determined to be abnormal, and the instruction to switch to the mechanical authentication mode is sent.

[0045] If the exit delay response degree is within the exit delay response interval, the exit authentication data packet accuracy is verified to obtain an exit data packet verification result reflecting transmission accuracy of the exit authentication data packet; the exit data packet verification result includes exit verification pass and exit verification fail, and when the exit data packet verification result is the exit verification pass, it indicates that an exit data packet sending verification value and an exit data packet receiving verification value are the same, and when the exit data packet verification result is the exit verification fail, it indicates that the exit data packet sending verification value and the exit data packet receiving verification value are different.

[0046] When the exit data packet verification result is the exit verification pass, the exit authentication transmission determination result is determined to be qualified, and the entry and exit matching bidirectional authentication is performed, otherwise, the exit authentication transmission determination result is determined to be abnormal.

[0047] The entry and exit matching bidirectional authentication is performed, and the specific process is as follows: The lock server is searched to determine whether the user has the entry authentication information, if not, the matching authentication result is recorded as authentication failure, the opening instruction is refused to be sent, and a prompt to switch to a mechanical opening mode is sent, if yes, the matching authentication result is recorded as authentication success, and the opening instruction is sent.

[0048] The exit path joining delay judgment, check and correction, and bidirectional matching mechanism make the exit authentication not a simple "credential and command" process, but a strict link with multiple checks. This can prevent forgery, replay, tampering, and intermediate attacks. In the entire authentication process, the judgment of communication success, delay, and check results is the quality control of the network channel itself, making the system more resistant to network fluctuations and spontaneous failures. The design of the exit authentication mechanism significantly improves the security, reliability, and authentication accuracy of the system. Through intelligent judgment and optimization of the authentication process, the system not only improves the authentication efficiency, but also enhances the fault tolerance and flexibility of the system.

[0049] The access control unlocking linkage detection module is used to detect the reliability of the access control unlocking linkage after triggering the entry and exit authentication mechanism selection to determine whether to adjust the retry mechanism and authentication timeout time to reduce the emergency unlocking response adjustment for false positives. As shown in Figure 3 , the access control unlocking linkage reliability detection flowchart of the intelligent access control emergency unlocking system for entry and exit bidirectional authentication unlocking provided by the embodiment of the application, the corresponding logic is: obtaining the electronic unlocking failure rate and the mechanical unlocking failure rate, coupling processing the electronic unlocking failure rate and the mechanical unlocking failure rate to obtain an unlocking linkage combined detection value representing the reliability of the access control unlocking linkage, modifying the unlocking linkage combined detection value based on the introduced time dimension attenuation factor to obtain an unlocking linkage combined modified value, comparing the unlocking linkage combined modified value with the stored unlocking reliability threshold value, when the unlocking linkage combined modified value is less than the unlocking reliability threshold value, performing emergency unlocking response adjustment, otherwise, monitoring the authentication success rate in the access control monitoring period and feeding back. Referring to Figure 3 , the access control unlocking linkage reliability detection is performed, and the specific steps are as follows: First, the electronic unlocking failure rate and the mechanical unlocking failure rate in the access control monitoring period are obtained through the system log, and the electronic unlocking failure rate and the mechanical unlocking failure rate are coupled to obtain an unlocking linkage combined detection value representing the reliability of the access control unlocking linkage. Coupling processing is the process of obtaining the limiting expression of the unlocking linkage combined detection value, and the limiting expression of the unlocking linkage combined detection value is: ; in the formula, PL represents the unlocking linkage combined detection value, PD represents the electronic unlocking failure rate, and PJ represents the mechanical unlocking failure rate.

[0050] Then, a time dimension attenuation factor for correcting the time attenuation of the door lock linkage reliability is introduced. The time dimension attenuation factor is set by professionals according to the standards in the field. The obtained time dimension attenuation factor is used to correct the opening lock linkage combination detection value to obtain the opening lock linkage combination correction value. The correction process is a product operation. The introduction of the time dimension attenuation factor can dynamically adjust the reliability judgment standard of the system according to the aging of the equipment or the increase of the use frequency. Through this correction, the system can accurately evaluate the current reliability of the equipment and avoid misjudgment or security vulnerabilities caused by equipment aging.

[0051] Further, the opening lock linkage combination correction value is compared with the stored opening lock reliability threshold value. When the opening lock linkage combination correction value is less than the opening lock reliability threshold value, the emergency opening lock response adjustment is performed, otherwise, the authentication success rate in the access control monitoring period is monitored through the system log and feedback is performed. The specific process of the emergency opening lock response adjustment is as follows: The opening lock linkage combination correction value is input into the retry number mapping table, and the maximum retry number threshold value for setting the maximum retry number of data packet sending is correspondingly output. It is judged whether the authentication success rate obtained in the access control monitoring period is lower than the authentication set value. If yes, the maximum retry number threshold value setting update is performed, that is, the maximum retry number of data packet sending is set to the maximum retry number threshold value, otherwise, the maximum retry number threshold value setting update is not performed. The retry number mapping table is obtained by pre-training the historical opening lock linkage combination correction value and the maximum retry number threshold value set by professionals according to the experience rule, and is used to describe the mapping relationship between the opening lock linkage combination correction value and the maximum retry number threshold value. By adjusting the retry number threshold value according to the opening lock linkage combination correction value, the system can intelligently improve the fault tolerance of the authentication request. If errors frequently occur during the authentication process, the system will automatically increase the retry number to improve the probability of authentication success. This dynamic adjustment helps to avoid system interruption caused by accidental authentication failure, thereby improving the reliability and stability of the access control system.

[0052] After setting the maximum retry count threshold, the initial authentication timeout time is set according to the obtained authentication timeout adjustment time length, that is, the initial authentication timeout time is set to the authentication timeout adjustment time length, and the authentication timeout adjustment time length is the output result obtained by inputting the lock linkage combination correction value into the authentication timeout adjustment mapping table. The authentication timeout adjustment mapping table is obtained by pre-training using historical lock linkage combination correction values and authentication timeout adjustment time lengths set by professionals according to experience rules, and is used to describe the mapping relationship between the lock linkage combination correction value and the authentication timeout adjustment time length. Adjusting the authentication timeout according to the correction value ensures that the waiting time is not too long during the authentication process, and can also adapt to authentication failures or unstable networks. By intelligently adjusting the timeout time, the system can maintain high authentication efficiency and avoid user inconvenience caused by excessively long authentication timeouts.

[0053] The electronic and mechanical unlocking failure rates are obtained and fed back within the access control monitoring period.

[0054] The emergency unlocking response adjustment mechanism enhances the fault tolerance, adaptability, and security of the access control system by intelligently adjusting the retry count, authentication timeout settings, and real-time monitoring feedback. The system can autonomously adjust the authentication strategy when facing network instability, device failures, and other issues, maintaining efficient and secure access control operations. This not only improves user experience but also enhances the reliability and flexibility of the access control system, ensuring smooth operation of the device in different environments and avoiding the impact of failures on system security.

[0055] In the intelligent access control system, electronic unlocking usually dominates, but mechanical unlocking is also a necessary backup path for the system. Over time and with changes in the use environment, mechanical components may experience wear, looseness, deformation, rust, and other issues. These problems gradually affect the reliability of mechanical unlocking, leading to increased unlocking torque, inaccurate angles, jamming, and failure. Therefore, as a further solution, the emergency unlocking response adjustment also includes: The mechanical unlocking failure rate is input into the lock maintenance cycle mapping set, and the maintenance adjustment cycle for setting the initial mechanical unlocking lock maintenance cycle is output. The mechanical unlocking rotation angle obtained by the rotary encoder is averaged to obtain the mechanical unlocking average rotation angle within the maintenance adjustment cycle. The lock maintenance cycle mapping set is obtained by pre-training using historical mechanical unlocking failure rates and maintenance adjustment cycles set by professionals according to experience rules, and is used to describe the mapping relationship between the mechanical unlocking failure rate and the maintenance adjustment cycle. Dynamically adjusting the maintenance cycle based on the mechanical unlocking failure rate can adjust the maintenance strategy according to the actual operating state of the device, avoiding excessive maintenance or delayed maintenance, improving use efficiency, and at the same time, precise maintenance cycle adjustment can reduce the risk of device failure due to long-term lack of maintenance, thereby reducing unlocking failures or system interruptions caused by device failures.

[0056] According to the obtained mechanical unlocking average rotation angle, a rotation unlocking deviation quantity reflecting the deviation degree of the mechanical unlocking average selection angle from the unlocking rotation angle setting value is obtained, the rotation unlocking deviation quantity is the absolute value of the difference between the mechanical unlocking average selection angle and the unlocking rotation angle setting value, and the rotation unlocking deviation quantity is input to the check trigger period adjustment mapping set to correspond to the output check trigger period adjustment value; the check trigger period adjustment mapping set is obtained by pre-training using historical rotation unlocking deviation quantities and check trigger period adjustment values set by professionals according to experience rules, and is used to describe the mapping relationship between the rotation unlocking deviation quantity and the check trigger period adjustment value; the continuous monitoring and adjustment of the deviation quantity help to maintain the operation accuracy of the mechanical lock, ensure that the equipment can run smoothly in the normal use process, and reduce the authentication failure caused by mechanical problems.

[0057] According to the output check trigger period adjustment value, the initial check trigger period is set, that is, the initial check trigger period is set to the check trigger period adjustment value; through the adjustment of the mechanical unlocking failure rate, the rotation angle deviation, and the check period, the system can accurately monitor the equipment health condition, and effectively improve the stability and safety of the access control system through dynamic adjustment of the maintenance period and the check frequency. This maintenance mechanism can identify potential failures in advance, reduce the risk of equipment damage, prolong the service life of the equipment, optimize the allocation of maintenance resources, and ensure that the access control system always operates efficiently and safely.

[0058] Overall, whether the user has the right to enter or exit the door is determined through user face recognition or card swiping authentication, which can effectively distinguish the need for authentication to open the door when the user enters or exits, and ensure the accuracy of the user's entry and exit track and time. Since the exit adopts the permission authentication mode to unlock, it depends on the premise that the user has the right to unlock normally. Once there is no permission for the personnel and emergency exit is needed, in order to ensure the safety of the user, a mechanical emergency exit mode is specially set.

[0059] In summary, the present application improves the safety, reliability and flexibility of the overall system through the bidirectional authentication mechanism, dynamic information transmission optimization and intelligent linkage detection technology. Compared with the prior art, not only can the authentication information be effectively avoided or misjudged, but also the network instability and other sudden situations can be responded to in real time, ensuring the smoothness and safety of the access control operation.
