Description

Technical Field

[0001] The present invention relates to the technical field of intelligent lock control, and particularly to an intelligent lock control security system and traceability management method based on multi-modal authentication. Background Art

[0002] In industrial fields such as electricity and energy, the zonal management and locking control of equipment are crucial for ensuring safe production. There are many problems with the traditional mechanical lock and key management models widely used currently: The large number and variety of keys make it difficult for operators to find and carry them, seriously affecting work efficiency; Although the unlocking and locking design simplifies the operation process, there is a risk of accidentally unlocking adjacent equipment, posing a serious hidden danger to safe production. In terms of key management, there are management loopholes in both manned and unmanned scenarios. Keys are easily lost, can be replicated, and there is a lack of effective authorization mechanisms, making it difficult to control security risks.

[0003] Existing locks are mostly civilian products, which are prone to corrosion and failure in harsh outdoor environments and lack reliability. At the same time, traditional management models rely on manual records and paper documents, making it difficult to achieve long-term preservation and rapid traceability of operation records, and facing difficulties in accident accountability. Although electronic lock control technologies have developed in recent years, existing solutions still have the problem of single functions: either only supporting physical keys or only supporting digital authorization, unable to meet the diverse needs in complex scenarios; Most electronic locks rely on external power supply, with limited applicability in outdoor or power-off environments; There is a lack of intelligent traceability management functions, making it difficult to achieve automated analysis of operation behaviors and abnormal warnings.

[0004] More prominently, existing systems perform poorly in dealing with emergencies. Mechanical emergency keys have problems such as chaotic hierarchical management and excessive generality, which easily lead to accidental unlocking across regions; The fault handling process is cumbersome, lacking remote verification and dynamic authorization capabilities, and prolonging the fault recovery time.

[0005] In summary, these problems severely restrict the improvement of the lock control management level in industrial sites, and there is an urgent need for an intelligent lock control security system and traceability management method based on multi-modal authentication. Summary of the Invention

[0006] Aiming at the defects of the above-mentioned existing technologies, the present invention provides an intelligent lock control security system and traceability management method based on multi-modal authentication, aiming to solve the problems of low operation efficiency, weak security management, insufficient intelligence level, and lack of emergency handling ability in the existing lock control system.

[0007] To achieve the above object, the technical solution adopted by the present invention is: an intelligent lock control security system based on multi-modal authentication, including a central module, a passive lock module, a security traceability module, and an intelligent key module. The central module is electrically connected to the security traceability module, and the central module is communicatively connected to the passive lock module and the intelligent key module. The passive lock module includes a trigger power-on component, an authentication unit, an unlocking unit, an emergency determination unit, a camera unit, and a log transmission unit. The intelligent key module activates the authentication unit through the trigger power-on component. The authentication unit is electrically connected to the unlocking unit and the emergency determination unit. The authentication unit and the emergency determination unit are respectively electrically connected to the log transmission unit. The emergency determination unit is electrically connected to the camera unit. The authentication unit and the camera unit are respectively communicatively connected to the central module. The security traceability module includes an inspection generation unit communicatively connected to the central module, an analysis and statistics unit electrically connected to the inspection generation unit, a missed inspection warning unit, and a permission recovery unit. The analysis and statistics unit is respectively electrically connected to the missed inspection warning unit and the permission recovery unit.

[0008] Based on the above, the beneficial effects of an intelligent lock control security system based on multi-modal authentication are to solve the problems of low operation efficiency, weak security management, insufficient intelligence, and lack of emergency handling ability in the existing lock control system; mainly reflected in:

[0009] 1. Through the collaborative work of the central module and the authorization module, the present invention adopts technical means such as a planning unit to generate an authorization time window and permission level, and a lending unit to generate an encrypted authorization code, which is used to achieve refined management and dynamic allocation of permissions, thus solving the problems of rigid authorization mechanism and extensive permission management in the traditional lock control system. Specifically, the planning unit can set different operation permissions and time ranges according to different positions, and the lending unit generates a temporary authorization code through an encryption algorithm to ensure the security and traceability of each lending operation;

[0010] 2. Through the dual-trigger mechanism of the magnetic control unit and the signal receiving unit in the passive lock module, combined with the self-powered design of the power-on unit, the present invention is used to achieve reliable activation and passive operation of the lock, thus solving the problems of electronic locks relying on external power sources and poor environmental adaptability. Specifically, the magnetic control unit generates an induced current through physical contact, and the signal receiving unit receives instructions through wireless communication. Both can independently trigger the power-on unit to supply power to the authentication unit, ensuring normal operation under various environmental conditions;

[0011] 3. Through the real-time processing of operation data by the analysis and statistics unit in the security traceability module of the present invention, combined with the task comparison function of the inspection generation unit, its function is to realize the intelligent monitoring and management of operation behaviors, thereby solving the problems of scattered records and insufficient analysis capabilities in traditional systems. Specifically, the analysis and statistics unit is used to identify abnormal operations, and the inspection generation unit automatically compares the actual operations with the preset tasks to promptly discover situations such as missed inspections and misoperations.

[0012] 4. Through the linkage mechanism between the emergency determination unit and the camera unit of the present invention, combined with the remote verification function of the central module, its function is to establish a multi-level emergency handling channel, thereby solving the problems of slow fault response and single handling method in traditional systems. Specifically, when the authentication fails, the emergency determination unit can initiate the on-site administrator identity verification process, or transmit the on-site picture to the central module through the camera unit for remote authorization, greatly improving the emergency handling efficiency.

[0013] Furthermore, the intelligent key module includes a magnetically controlled key component and a wireless key component. The trigger power-on component includes a magnetically controlled unit, a signal receiving unit, and a power-on unit. The magnetically controlled key component triggers the magnetically controlled unit through physical contact. The wireless key component is communicatively connected to the signal receiving unit. The magnetically controlled unit and the signal receiving unit are respectively electrically connected to the power-on unit, and the power-on unit is electrically connected to the authentication unit.

[0014] Based on the above, the beneficial effects of the magnetically controlled key component and the wireless key component are to provide diverse unlocking method options, thereby solving the problem of insufficient reliability of a single unlocking method. In normal situations, the wireless key is used for convenient operation, and when there is signal interference or power interruption, it automatically switches to the magnetically controlled key to ensure the availability of the system under various working conditions.

[0015] Furthermore, the intelligent lock control security system further includes a portable module and an authorization module. The central module is electrically connected to the authorization module, and the central module is communicatively connected to the portable module. The authorization module includes a planning unit, a lending unit, and an authorization communication unit. The planning unit is used to generate an authorization time window and a permission level. The lending unit is used to generate an encrypted authorization code. The central module is electrically connected to the planning unit and the lending unit, and the planning unit and the lending unit are respectively electrically connected to the authorization communication unit.

[0016] Based on the above, the authorization module realizes refined control of permissions through the planning unit, and can set different authorization time windows and permission levels according to different work requirements. Its function is to ensure the timeliness and pertinence of permission allocation, thus solving the problem of single permission setting and inflexible adjustment in traditional systems; the borrowing unit adopts the technical means of generating dynamic authorization codes through encryption algorithms, and its function is to ensure the security of temporary permissions and prevent the authorization information from being tampered with or misused, thus solving the security hidden danger problem in the traditional key borrowing management; the communication connection between the portable module and the central module supports remote operation and status query on the mobile side, providing convenience for on-site operations, thus solving the limitation that traditional systems must rely on fixed terminals for operations; the collaborative working mode of the planning unit and the borrowing unit realizes the unified management of regular permissions and temporary permissions, forming a complete permission management system, thus solving the problem of disjoint management of long-term permissions and temporary permissions in traditional systems.

[0017] Further, the portable module includes an unlocking request unit and an authentication mode determination unit. The unlocking request unit is communicatively connected to the central module, and the authorization communication unit is communicatively connected to the authentication mode determination unit.

[0018] Based on the above, the real-time communication connection between the unlocking request unit and the central module is used to realize the real-time transmission and status feedback of the request for the authorization code from the intelligent key module, ensuring that the operation request can be instantaneously responded to and processed by the system, thus solving the problem of operation response delay in traditional systems; the communication connection between the authentication mode determination unit and the authorization communication unit is used to automatically select the optimal key module (magnetic control key module or wireless key module) according to the preset permission policies (such as planned authorization, temporary authorization, and emergency authorization), thus solving the problem that a single authentication method cannot meet the requirements of different scenarios.

[0019] Further, the authentication mode determination unit is communicatively connected to the magnetic control key assembly. The magnetic control key assembly is used to activate the authentication process through the magnetic control unit, and only allows physical contact with the magnetic control unit to trigger within the authorization time window.

[0020] Based on the above, the forced limit function of the authorization time window is used to ensure that the magnetic control key assembly only has the operation permission within the preset validity period and automatically becomes invalid after expiration, thus solving the management problem that the permissions of traditional mechanical keys are valid for a long time and cannot be recovered.

[0021] Further, the authentication mode determination unit is communicatively connected to the wireless key assembly. The wireless key assembly is used to activate the authentication process through the signal receiving unit, and only allows the signal receiving unit to be activated by wireless signals to trigger within the authorization time window.

[0022] Based on the above, the mandatory limit function of the authorization time window is to ensure that the wireless key component only has the operation authority within the preset validity period and automatically becomes invalid after the timeout, thus solving the management problem that the authority of the traditional mechanical key is valid for a long time and cannot be recovered.

[0023] The present invention discloses a traceability management method, comprising the following steps:

[0024] S1. Set the permission level and time window through the authorization module, and generate three encrypted authorization codes: planned authorization, temporary authorization, or emergency authorization;

[0025] S2. After receiving the authorization, the intelligent key module triggers the authentication unit of the passive lock module by magnetic control or wireless means;

[0026] S3. The authentication unit determines whether the authorization code matches the ID code of the passive lock module;

[0027] S4. If the match is successful, the unlocking unit performs the unlocking operation, and the log feedback unit records the operation data and uploads it to the central module;

[0028] S5. If the match fails, the authentication unit further determines whether the failure reason is permission expiration or device failure;

[0029] S6. If the failure reason is permission expiration, the central module triggers the permission recovery unit to recover the permission;

[0030] S7. If the failure reason is device failure, the emergency determination unit starts the verification process;

[0031] S8. The inspection generation unit of the security traceability module generates an inspection report, and the analysis and statistics unit performs abnormal behavior analysis and statistical processing on the operation data, and triggers a missed inspection warning or permission recovery after comparing with the preset tasks.

[0032] Based on the above, setting the permission level and time window in step S1 and generating three types of encrypted authorization codes has the beneficial effect of realizing refined hierarchical classification and dynamic encryption management of permissions, thus solving the problems of extensive permission allocation and single security mechanism in traditional systems; the intelligent key module in step S2 triggers the authentication unit through magnetic control or wireless means, and its beneficial effect is to support a multi-modal authentication trigger mechanism, thus solving the problems of traditional locks relying on a single physical trigger and poor scene adaptability; the authentication unit in step S3 matches the authorization code with the lock ID code, and its beneficial effect is to ensure the unique binding of the operation permission and the target device, thus solving the risk of misoperation that may be caused by unlocking the lock; the log transmission unit in step S4 uploads the operation data in real time, and its beneficial effect is to realize the full traceability of operation behaviors, thus solving the problems of easy loss of traditional paper records and inability to synchronize in real time; judging the reason for authentication failure (permission expiration or device failure) in step S5, and its beneficial effect is to accurately locate the type of failure, thus solving the problems of low efficiency of traditional system fault troubleshooting and high misjudgment rate; the permission recovery unit in step S6 automatically recovers the expired permissions, and its beneficial effect is to block the subsequent risks of unauthorized operations, thus solving the security vulnerability problems caused by the lag of manual permission recovery; the emergency determination unit in step S7 starts the verification process, and its beneficial effect is to establish a multi-level emergency response mechanism, thus solving the problems of single emergency unlocking process and low recovery efficiency in traditional systems; the analysis and statistics unit in step S8 compares the preset tasks and triggers an alarm, and its beneficial effect is to realize the automated closed-loop management of inspection tasks, thus solving the problems of high missed inspection rate and management disconnection in manual inspections.

[0033] Further, in the above step S7, the verification process includes on-site verification, specifically: the administrator manually updates the authorization code of the magnetic control key component, and the user triggers the magnetic control unit again to perform the unlocking operation.

[0034] Further, in the above step S7, the verification process also includes remote verification, specifically: after the central module verifies the user's permissions, it updates the authorization code to the wireless key component through an encrypted communication protocol.

[0035] Further, the operation information recorded by the log transmission unit includes the authentication result, the reason for failure, the emergency handling mode, and the verification result, and is uploaded to the database of the central module in real time through an encrypted communication protocol.

[0036] To more clearly elaborate the above features of the present invention and the purposes to be achieved, the following further describes the present invention in combination with the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In this embodiment, the intelligent lock control security system further includes a portable module 2 and an authorization module 3. The central module 1 is electrically connected to the authorization module 3, and the central module 1 is communicatively connected to the portable module 2. The authorization module 3 includes a planning unit 31, a lending unit 32, and an authorization communication unit 33. The planning unit 31 is used to generate an authorization time window and permission level. The lending unit 32 is used to generate an encrypted authorization code. The central module 1 is electrically connected to the planning unit 31 and the lending unit 32.

[0045] In this embodiment, the planning unit 31 supports periodic authorization and permission level division; the lending unit 32 uses dynamic encryption to generate a temporary authorization code; the authorization communication unit 33 issues the authorization code to the intelligent key module 6 through a communication protocol.

[0046] In this embodiment, the portable module 2 includes an unlocking request unit 21 and an authentication mode determination unit 22. The unlocking request unit 21 is communicatively connected to the central module 1, and the authorization communication unit 33 is communicatively connected to the authentication mode determination unit 22; the authentication mode determination unit 22 automatically selects the magnetically controlled key module 61 or the wireless key module 62 as the authentication carrier according to the type of authorization code issued by the authorization communication unit 33.

[0047] In this embodiment, the portable module 2 is a mobile phone APP, and its functions include:

[0048] An unlocking request unit 21: provides an operation management interface, supports task application, permission application, operation record query, and unlocking by QR code scanning;

[0049] An authentication mode determination unit 22: automatically selects the magnetic control key component 61 or the wireless key component 62 as the authentication carrier according to the authorization code type (planned authorization, temporary authorization, or emergency authorization) and the network status (such as the presence or absence of a 4G signal); if the network is normal, the wireless key component 62 is preferentially activated via Bluetooth or wireless signal; if the network is interrupted, the magnetic control key component 61 is switched to.

[0050] In this embodiment, the authentication mode determination unit 22 is communicatively connected to the magnetic control key component 61, and the magnetic control key component 61 is used to activate the authentication process through the magnetic control unit 411, and only allows physical contact with the magnetic control unit 411 to trigger within the authorized time window.

[0052] The present invention also discloses a traceability management method, including the following steps:

[0053] S1. Set the permission level and time window through the authorization module 3, and generate three encrypted authorization codes: planned authorization, temporary authorization, or emergency authorization;

[0054] S2. After receiving the authorization, the intelligent key module 6 triggers the authentication unit 42 of the passive lock module 4 magnetically or wirelessly;

[0055] S3. The authentication unit 42 determines whether the authorization code matches the ID code of the passive lock module 4;

[0056] S4. If the match is successful, the unlocking unit 43 performs the unlocking operation, and the log transmission unit 46 records the operation data and uploads it to the central module 1;

[0057] S5. If the match fails, the authentication unit 42 further determines whether the failure reason is permission expiration or device failure;

[0058] S6. If the failure reason is permission expiration, the central module 1 triggers the permission recovery unit 54 to recover the permission;

[0059] S7. If the failure reason is device failure, the emergency determination unit 44 starts the verification process;

[0060] In S8, the inspection generation unit 51 of the security traceability module 5 generates an inspection report. The analysis and statistics unit 52 conducts abnormal behavior analysis and statistical processing on the operation data, and triggers a missed inspection warning 53 or permission recovery 54 after comparing with the preset tasks.

[0061] In this embodiment, in step S7, the verification process includes on-site verification, specifically: the administrator manually updates the authorization code of the magnetic control key component 61, and the user triggers the magnetic control unit 411 again to perform the unlocking operation.

[0062] In this embodiment, in step S7, the verification process further includes remote verification, specifically: after the central module 1 verifies the user's permission, it updates the authorization code to the wireless key component 62 through the encrypted communication protocol.

[0063] In this embodiment, the operation information recorded by the log transmission unit 46 includes the authentication result, the reason for failure, the emergency handling mode, and the verification result, and is uploaded to the database of the central module 1 in real time through the encrypted communication protocol.

[0064] In this embodiment, the inspection generation unit 51 of the security traceability module 5 generates an inspection report, the analysis and statistics unit 52 identifies abnormal operations, the missed inspection warning unit 53 pushes warning information, and the permission recovery unit 54 automatically recovers invalid permissions.

[0065] In summary, the specific implementation of the present invention is as follows:

[0066] Starting from the user permission setting of the unlocking request unit 21 of the portable module 2 received by the central module 1, the planning unit 31 of the authorization module 3 generates a permission level and a time window according to the operation requirements. The lending unit 32 dynamically generates an encrypted authorization code (planned authorization, temporary authorization, or emergency authorization). The central module 1 issues the authorization code to the authentication mode determination unit 22 of the portable module 2 through the authorization communication unit 33. The authentication mode determination unit 22 automatically selects the magnetic control key component 61 or the wireless key component 62 as the authentication carrier according to the type of the authorization code;

[0067] If the magnetic control key component 61 is selected, the operator triggers the magnetic control unit 411 of the passive lock module 4 through physical contact to activate the power supply unit 413 to supply power to the authentication unit 42. If the wireless key component 62 is selected, the signal receiving unit 412 is triggered through a wireless signal to also activate the power supply unit 413. The authentication unit 42 matches the authorization code with the ID code of the passive lock module 4: if the match is successful, the unlocking unit 43 performs the unlocking action, and the log transmission unit 46 records the operation data and uploads it to the central module 1 in real time; if the match fails, the authentication unit 42 further determines whether the reason for failure is permission expiration or equipment failure;

[0068] When the permission fails, the permission recovery unit 54 of the security traceability module 5 is triggered by the central module 1 to automatically recover the permission; when a device failure occurs, the emergency determination unit 44 starts the verification process: for on-site verification, the administrator manually updates the authorization code of the magnetic control key component 61 and triggers the magnetic control unit 411 again, and for remote verification, the central module 1 updates the authorization code of the wireless key component 62 through a wireless signal;

[0069] The patrol inspection generation unit 51 of the security traceability module 5 generates a patrol inspection report. The analysis and statistics unit 52 performs abnormal analysis on the operation data and compares it with the preset tasks. If undetected inspections or abnormalities are found, the undetected inspection alarm unit 53 issues an alarm, and the permission recovery unit 54 synchronously executes permission recovery. The authentication results, failure reasons, and verification information recorded by the log transmission unit 46 are uploaded to the database of the central module 1 through encrypted communication to complete the closed-loop management of the entire process.

[0070] The above is only the optimal solution embodiment of the present invention and is not used to limit the present invention. Various modifications or substitutions made by those skilled in the art to the present invention without departing from the essence and protection scope of the present invention should also be within the protection scope of the present invention.
