Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent lock control and relates to an intelligent lock control system for a power dispatching room. Background Art

[0002] The power dispatching room is the core hub of modern power grid operations, housing numerous critical power facilities. These facilities are often equipped with locks to ensure safe and accurate operation. By controlling the operation of these devices, grid topology can be modified, ensuring the stability and security of the power system.

[0003] As power systems become increasingly complex, traditional mechanical locks and manual management methods are no longer able to meet the requirements for high security, traceability, and centralized control. Intelligent lock control systems not only enable precise management of personnel access rights, but also monitor device status in real time and log all operations, effectively preventing misuse and unauthorized access, providing a solid foundation for the continued stable operation of power systems.

[0004] At present, existing technologies have proposed intelligent electric lock management and control systems for power dispatching rooms. For example, the invention patent with publication number CN106683251A proposes an intelligent electric lock management and control system for computer rooms. By installing an intelligent electric lock with integrated identity authentication and status reporting functions on the computer room door, and combining it with a smartphone with an integrated dedicated APP to realize on-site code reading and operation authority verification, complete identity authentication and unlocking operations, and realize integrated intelligent management of locks, it effectively improves the efficiency and intelligence level of computer room security management.

[0005] Another example is the invention patent with publication number CN113421359A, which proposes a smart lock control system and method for power cabinets. The user's mobile terminal APP scans the unique QR code of the power cabinet to trigger Bluetooth near-field communication to complete permission verification. After successful verification, the electronic lock is automatically opened and the NB-IoT module is used to realize status monitoring and data transmission, realizing contactless intelligent security management and full-process traceable operation and maintenance, thereby improving the management efficiency and safety of the power cabinet.

[0006] Although the above two existing solutions have achieved certain results in the intelligent lock control of power dispatching rooms, they still have the following shortcomings:

[0007] First, the existing technology only independently controls the locks of a single object in the power cabinet, and lacks a linkage wake-up mechanism between the door locks and equipment door locks in the overall environment of the power dispatching room. As a result, all locks need to be in standby mode for a long time to respond to operation instructions, resulting in unnecessary energy consumption.

[0008] Secondly, power grid operations are highly time-dependent and state-dependent. Each operation step must strictly follow the established operation sequence and time limit requirements. However, the existing intelligent lock control system only implements key-based identity recognition and authority control. It is unable to dynamically adjust the lock opening logic according to the prescribed operation sequence and control the operation time limit for a single device operation. As a result, on-site operations lack process guidance and time constraints, and it is difficult to form an effective real-time audit basis for the operation process. Once an abnormality occurs, it is often necessary to locate the problem by tracing back the operation log one by one afterwards, which significantly increases the operation and maintenance costs and risks. Summary of the Invention

[0009] In view of this, in order to solve the problems raised in the above background technology, the present invention provides an intelligent lock control system for a power dispatching room.

[0010] The purpose of the present invention can be achieved through the following technical solutions: A smart lock control system for a power dispatching room, including: an electronic operation ticket issuance module, used to send electronic operation tickets to the operator terminal and the smart locks for entering and leaving the power dispatching room.

[0011] The door lock linkage wake-up module is used to wake up the smart locks of the equipment doors in the electronic operation ticket and switch them to standby state when the smart locks at the entrance and exit of the power dispatching room are verified and opened through the electronic operation ticket.

[0012] The dynamic sequence control module is used to dynamically control the opening logic of the device door intelligent lock to perform sequential or synchronous operations according to the operation sequence in the electronic operation ticket.

[0013] The operation time limit monitoring module is used to start the operation time limit countdown when the smart lock of any target device door is opened, and detect in real time whether a single operation exceeds the preset time threshold.

[0014] The timeout graded response module is used to trigger the sound and light warning and remote alarm signal of the device door smart lock in sequence after the operation timeout.

[0015] The safety locking execution module is used to automatically and forcibly lock the timed-out device door lock that is currently in the open state when no manual intervention signal is received after the timeout and the operation time limit countdown is exhausted.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) After the operator completes identity authentication through the smart lock at the door and opens the machine room door, the present invention automatically wakes up the smart lock of the target device door and puts it into standby mode, while the other non-related locks remain in sleep mode, thereby effectively reducing the overall power consumption of the system.

[0017] (2) The present invention implements mandatory verification of the pre-sequence state or the opening logic of waiting for the entire group to be ready on the target device door smart lock according to the operation sequence in the electronic operation ticket, effectively preventing the risk of single point failure in operation step skipping and collaborative operation, and effectively solving the problems of misoperation, safety hazards and low efficiency caused by non-standard step execution or asynchronous equipment coordination in power grid operation and maintenance.

[0018] (3) The present invention starts an independent countdown when the intelligent lock of the equipment door is opened, compares the current operation time with the preset time limit threshold in real time, and triggers a hierarchical response mechanism when the time exceeds the limit. It automatically performs forced locking when necessary, effectively dealing with the risk of overtime operation caused by personnel detention, operation delays or emergencies, and providing accurate time supervision for the operation of key equipment.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1 As shown, the present invention provides an intelligent lock control system for a power dispatching room, comprising an electronic operation ticket issuance module, a door lock linkage wake-up module, a dynamic sequence control module, an operation time limit monitoring module, a timeout graded response module, and a safety lock execution module. All modules are connected in the above order.

[0025] The electronic operation ticket issuance module is used to send electronic operation tickets to the operator terminal and the smart locks for entering and leaving the power dispatching room.

[0026] The electronic operation ticket includes a unique identifier for the operation task, identity authentication information and biometric template of the authorized operator, a physical location code group of the target device door smart lock, a sequential operation identifier, a synchronous operation identifier, an allowed operation time threshold for each device door smart lock, and arrival timestamp verification data.

[0027] It should be noted that the operation task unique identifier is used to uniquely identify each operation task to ensure the independence and traceability of the task.

[0028] The authorized operator's identity authentication information and biometric template are usually entered into the electronic operation ticket during the operator registration and authorization process, including but not limited to biometric data such as fingerprints and facial recognition, as well as traditional authentication information such as user name and password, which can further enhance security and prevent unauthorized access.

[0029] The physical location coding group of the target device door smart lock is based on the actual layout and planning of the equipment in the power dispatching room. When installing the smart lock, a unique physical location code is assigned to each smart lock, which helps the system to accurately send instructions to the correct lock and ensure the accuracy of the operation process.

[0030] Sequential operation identifiers and synchronous operation identifiers are set by administrators based on specific operation processes and security requirements. Sequential operations ensure that certain key steps are completed in a predetermined order, while synchronous operations allow related tasks to be processed in parallel to improve efficiency.

[0031] The allowable operation time threshold of each device door smart lock is set according to actual needs and safety regulations. The maximum allowable operation time of each lock is determined based on historical data analysis, risk assessment and industry standards, which helps monitor the time consumption during the operation and prevent safety hazards or operational errors caused by long-term non-closing.

[0032] The arrival timestamp verification data is generated when the electronic operation ticket is issued. It contains information about the operator's expected arrival time. It is compared with the operator's actual arrival time to verify whether the operation was performed within the valid time, and it also adds an extra layer of security check mechanism.

[0033] The issuance of electronic operation tickets ensures that only authorized operators can enter the power dispatching room and perform specific operation tasks, reducing the risk of physical keys being lost or stolen and enhancing the security of the access control system.

[0034] refer to Figure 2 As shown, the door lock linkage wake-up module is used to wake up the smart lock of the equipment door in the electronic operation ticket and switch it to standby state when the smart lock of the door entering and leaving the power dispatching room is verified and opened through the electronic operation ticket.

[0035] Specifically, the steps for the smart locks at the entrance and exit of the power dispatching room to be verified and opened through the electronic operation ticket are as follows: when the smart locks at the entrance and exit of the power dispatching room receive the receipt signal of the electronic operation ticket, they automatically switch from sleep mode to standby mode, and at the same time start the infrared sensor in front of the door to start monitoring.

[0036] The infrared sensor is installed just above the door to ensure that it can effectively cover the door area. If necessary, multiple infrared sensors can be installed at different locations of the door to form cross coverage to avoid blind spots.

[0037] When an operator approaches the door, the infrared sensor can detect human body heat or movement, thereby identifying someone trying to enter the power dispatch room.

[0038] After the infrared sensor detects that the operator enters its detection range, it automatically triggers the smart lock for entering and leaving the door to verify the unique identifier of the operation task, the authorized operator's identity authentication information and the arrival timestamp verification data in the electronic operation ticket based on the operator's status close to the door lock.

[0039] If the operator's arrival time is within the valid interval formed by the electronic operation ticket issuance time and the arrival timestamp in the electronic operation ticket, the biometric verification will continue and be matched with the biometric template pre-stored in the electronic operation ticket.

[0040] Specifically, different biometric verification methods are performed according to the operator's state of approaching the door lock as follows: when the operator enters the effective detection area of ​​the infrared sensor for the first time, it recognizes that someone is approaching but does not immediately trigger biometric verification. The smart lock for entering and leaving the door begins to preload the electronic operation ticket information related to the area and prepares a data set containing the operator's facial features for comparison and verification of the biometric template for the facial recognition system.

[0041] If the operator’s arrival time exceeds the arrival timestamp in the electronic operation ticket, a secondary biometric verification is mandatory.

[0042] Specifically, secondary biometric verification includes but is not limited to multiple types of biometrics such as fingerprint recognition, facial recognition, and iris recognition to increase the complexity and accuracy of verification. At the same time, the operator is also required to provide a dynamically generated one-time password as an additional security layer.

[0043] It should be noted that secondary verification ensures that even if someone holds a legitimate operation ticket, the operation must be completed within the specified time to prevent the operation ticket from being abused or stolen.

[0044] After all verifications are passed, the smart door lock will be opened and an opening event log containing a unique identifier of the operation task will be generated.

[0045] Monitor the opening event log in real time, and when the unique identifier of the operation task is identified, immediately broadcast the encrypted wake-up command to the physical location coding group of the target device door smart lock recorded in the electronic operation ticket.

[0046] The encrypted wake-up instruction contains necessary control information, so that the target device can switch from a deep sleep state to a standby state to prepare for further operation. To ensure security, the instruction is encrypted to prevent unauthorized third parties from intercepting and tampering.

[0047] The directed broadcast means that only devices with the correct physical location code will respond to the message.

[0048] Specifically, according to the found unique identifier of the operation task, the physical location code group of the target device door smart lock associated with it is searched in the electronic operation ticket.

[0049] More specifically, the obtained physical location code group of the target device door smart lock is used as address information, and the encrypted wake-up instruction is sent to the designated device door smart lock through the network.

[0050] Verify the consistency of the device code in the returned communication signal, and switch the corresponding device door smart lock from deep sleep state to standby state.

[0051] Specifically, after sending the wake-up command, the door lock needs to wait for a confirmation reply from the target device door smart lock. These replies contain the device's own coding information so that the system can check again whether it actually corresponds to the device pointed to when the command was originally issued.

[0052] More specifically, once the verification is successful, that is, it is confirmed that the returned device code is consistent with the expectation, the corresponding device door smart lock will switch from deep sleep state to standby state, ready to accept the next possible operation command.

[0053] The dynamic sequence control module is used to dynamically control the opening logic of the device door smart lock to perform sequential operation or synchronous operation according to the operation sequence in the electronic operation ticket.

[0054] This linkage mechanism ensures a smoother workflow from external entry to internal operation, and the device door smart lock remains in deep sleep mode to save power consumption.

[0055] The sequential operation refers to an operation in which there is no direct electrical coupling between devices, but there is an operation sequence between them.

[0056] Specifically, the specific steps of the opening logic of the device door smart lock for sequential operation are as follows: receiving the standby state signal of each device door smart lock and retrieving the sequential operation identifier in the electronic operation ticket.

[0057] Acquire the locking status signal of the previous target device door smart lock in real time, verify the authenticity and validity of the locking status signal, and generate a verification pass instruction after confirming that the lock is in place.

[0058] It should be noted that in order to obtain the locking status signal of the previous target device door smart lock, a magnetic proximity sensor is usually used to detect whether the door is closed, and an electric lock tongue feedback sensor detection device is used to confirm whether the door is actually locked. This combination can not only accurately judge the status of the door, but also link with the smart lock control system to provide real-time feedback of status information to ensure the safety and reliability of the operation process.

[0059] Verify the consistency of the current operation steps with the operation ticket sequence, check the validity period of the authorized operator's identity authentication, send an electronic unlocking command to the target device door smart lock, and trigger its mechanical unlocking mechanism to perform the unlocking action.

[0060] The electronic unlocking command contains the necessary control information for triggering the mechanical unlocking mechanism of the device door.

[0061] Specifically, compare whether the actual operation steps currently being performed match the predetermined sequence in the electronic operation ticket, verify whether the person performing the current operation holds valid identity authentication information, and confirm that he or she is still within the authorization validity period when operating. After confirming the consistency of the operation steps and the validity of the identity authentication, the smart lock will generate an electronic unlocking instruction for the smart lock of the specific target device door based on the relevant information in the electronic operation ticket. After the smart lock of the target device door receives the encrypted unlocking instruction, it first decrypts the instruction content, and then triggers the internal mechanical unlocking mechanism to perform the actual unlocking action, allowing the operator to enter or approach the equipment for maintenance, inspection, etc.

[0062] Continuously monitor the opening status of the current device door, send a preparation instruction to the next sequential device after the current device door is locked in place, and receive the ready confirmation signal returned by the preparation device.

[0063] Specifically, when the operator completes the operation of the current device and performs the locking action, the smart lock will receive a locking status signal. After confirming that the lock is in place, the smart lock will update the status of the current device door to "locked" in the electronic operation ticket and generate a corresponding log record. According to the sequential operation identifier in the electronic operation ticket, the next target device to be operated is determined, and an encrypted preparatory instruction is sent to the target device to notify it to prepare to enter the standby state to accept further operation commands. After receiving the preparatory instruction, the target device will perform necessary self-test procedures, such as checking its own hardware status, software version, etc. After ensuring that everything is normal, it returns a ready confirmation signal to the main control system.

[0064] Record the status conversion log of each equipment door in real time and update the current progress status of the electronic operation ticket.

[0065] It should be noted that detailed logging not only helps with post-audit, but also helps identify potential problems and facilitates subsequent improvements and optimizations.

[0066] By setting a clear operating sequence, safety hazards caused by incorrect operating sequences can be avoided.

[0067] The synchronization operation is an operation between functionally linked devices.

[0068] Specifically, the specific logical steps for the synchronous operation of the device door smart lock are as follows: receiving the synchronous operation identifier and the target device group physical location code set in the electronic operation ticket.

[0069] Send preparation instructions in parallel to a group of associated device door smart locks configured for synchronous operation, verify the ready status signal returned by each associated device door smart lock, and confirm that all members in the device group have reached the operational conditions.

[0070] It should be noted that all members of the device group meet the operational conditions, which means that each device door smart lock must be in good working condition, running the correct firmware version, and without software errors or abnormalities. At the same time, ensure that all device door smart locks are connected to a stable power supply to avoid operation failure or interruption due to power problems.

[0071] The electronic unlocking command is synchronously sent to all associated door smart locks of the functional linkage device group, triggering the parallel electric driving unlocking action of multiple door locks at the same time.

[0072] Real-time monitoring function links the coordinated opening status of the equipment group. When it is detected that any equipment door does not respond to opening, it will immediately send a stop command to all related equipment doors and trigger the linkage lock.

[0073] During the synchronous operation process, the operation time data of each device door is continuously compared. When non-corresponding operation progress occurs, the operation status of each device door is automatically coordinated and the collaborative operation log of the functional linkage device group is recorded.

[0074] It should be noted that the non-corresponding operation progress is affected by differences in opening and closing times, inconsistent operating states, loss or delay of feedback signals, and environmental factors.

[0075] The difference in unlocking and locking times refers to the fact that some devices respond quickly and have completed unlocking or locking, while other devices fail to complete the task in time due to communication delays, mechanical stalls, and other reasons. In this case, a reasonable synchronization waiting window can be set to allow a certain time difference within this time to avoid frequent triggering and aborting. Unlocking and locking commands can be resent to unresponsive devices individually to attempt to resume their operation. If a device fails to respond multiple times, it will be marked as an abnormal device and temporarily isolated from the current synchronization group to prevent it from slowing down the overall process.

[0076] Inconsistent operating states mean that some devices are in standby or ready states, while others may be in error or alarm states due to faults, software anomalies, and other reasons. This can be solved by unifying all device states to a base state, such as "standby," to ensure a consistent starting point for subsequent operations. Devices in abnormal states can then be diagnosed and initially repaired, such as restarting modules and clearing caches. If a device cannot automatically recover, the system will issue an alarm and prompt operations personnel to intervene and conduct an inspection.

[0077] Feedback signal loss or delay refers to a device failing to send a confirmation signal to the control system in a timely manner, causing the system to misjudge its operating status. In this case, you can regularly poll the device's online status to ensure that the communication link is normal.

[0078] Environmental factors refer to external environmental changes such as temperature, humidity, and vibration that affect the operating efficiency of some devices, causing them to lag behind other devices. In this case, environmental sensing modules such as temperature and humidity sensors can be integrated to monitor and warn of abnormal environmental conditions in real time. These sensors can then automatically adjust device operating parameters, such as motor drive voltage and communication frequency, based on this environmental data, improving device adaptability.

[0079] Update the group status mark in the electronic operation ticket and send a completion confirmation signal after completing all synchronous operation steps.

[0080] In synchronous operation mode, multiple devices can respond almost simultaneously, speeding up the overall operation rhythm.

[0081] The operation time limit monitoring module is used to start the operation time limit countdown when the smart lock of any target device door is opened, and to detect in real time whether a single operation exceeds a preset time threshold.

[0082] Specifically, at the moment when the smart lock of any target device door receives the electronic unlocking command and is successfully opened, the countdown for the independent operation time limit for the device door is started.

[0083] Extract the allowed operation time threshold parameter corresponding to the target device door smart lock from the currently valid electronic operation ticket.

[0084] The threshold parameter of the allowed operation time is set according to the average operation time of similar tasks in the past to avoid frequent false triggering of the timeout mechanism. For example, the daily inspection operation is set to Minutes, data collection or monitoring operations are set to Minutes, simple maintenance, such as restarting, plugging and unplugging modules minutes, medium complexity maintenance, such as replacing parts, is set to minutes, advanced configuration or debugging operations are set to minute.

[0085] The duration of the device door being in the open state is monitored in real time, and the open duration monitored in real time is continuously compared with the extracted allowed operation time threshold.

[0086] Specifically, when the magnetic proximity sensor and electric lock tongue feedback sensor on the device door detect that the door changes from "locked" to "open", an opening timestamp will be recorded, and the difference between the current time and the opening timestamp will be used as the opening state duration of the device door.

[0087] When the monitoring open duration reaches the allowed operation duration threshold, the current operation is determined to be in a timeout state.

[0088] Generates a timeout status flag for the device door smart lock.

[0089] The timeout status mark is updated in real time to the corresponding operation progress record of the electronic operation ticket.

[0090] It should be noted that updating the timeout status mark to the corresponding operation progress record of the electronic operation ticket in real time helps to review and analyze the entire operation process and ensure that each step is traceable.

[0091] The operation time limit monitoring module uses the "time dimension" to perform safety control and process management on each operation, ensuring that the equipment door will not be open for a long time, preventing potential risks, and providing reliable data support and decision-making basis for operation and maintenance management.

[0092] refer to Figure 3 As shown, the timeout graded response module is used to trigger the sound and light warning and remote alarm signal of the device door smart lock in sequence after the operation times out.

[0093] Specifically, the specific implementation process of the sound and light warning is as follows: when the timeout status mark of the target device door smart lock is detected from the corresponding operation progress record of the electronic operation ticket, an sound and light warning start instruction is generated for the device door.

[0094] The sound and light warning start instruction includes the equipment door code, the operation task unique identifier, the authorized operator identity authentication information, the timeout mark time and the actual operation time.

[0095] Send an audio and visual warning start command to the timeout device door smart lock, triggering its built-in acoustic alarm device and optical warning device to synchronously activate the initial intensity level of the warning signal.

[0096] The warning signal of the initial intensity level includes an initial acoustic warning device warning signal and an initial optical warning device warning signal.

[0097] The initial acoustic alarm device warning signal usually selects a moderate frequency range, such as 3kHz, and chirps intermittently, for example, once per second, and the volume is set to a medium level, about 70dB.

[0098] The initial optical warning device warning signal usually uses a yellow flashing light to remind the operator of the current situation. The flashing frequency can be selected to be slower, such as once or twice per second, and the brightness is set to medium intensity to ensure that it can be clearly seen under normal lighting conditions, but not too dazzling to affect the vision.

[0099] Monitor the opening status of the device door. If the timeout state persists and no effective manual intervention signal is received, control the output intensity of the acoustic alarm device and the optical warning device to increase in stages according to the preset time nodes.

[0100] Specifically, the output intensity can be enhanced in stages according to preset time nodes and can be divided into three enhancement stages.

[0101] If the timeout status persists for more than 1 minute and is not resolved, it enters the first reinforcement stage. If there is no improvement after a period of time, such as an additional 2 minutes, it enters the second reinforcement stage. After a longer period of time, such as a total of 5 minutes, it enters the final reinforcement stage.

[0102] The acoustic alarm is installed at a volume of 80dB in the first enhancement stage, with continuous beeps or faster rhythms, such as once every half a second, at a volume of 90dB in the second enhancement stage, with a higher frequency, such as 4kHz, and a fast flashing rhythm, such as twice per second, and at the final enhancement stage with a volume of more than 100dB, an extremely high frequency, such as 5kHz, and a continuous high-pitched alarm.

[0103] The optical warning device flashes yellow light in the first enhancement stage at a faster flashing frequency, such as twice per second, with increased brightness. In the second enhancement stage, the light flashes red light quickly, such as three times per second, with high brightness. In the final enhancement stage, the light flashes red light extremely quickly, such as five times per second, with the highest brightness.

[0104] Through this phased enhancement mechanism, the warning effect can be gradually improved without causing too much interference, ensuring that the attention of relevant personnel can be quickly attracted and abnormal situations can be handled in a timely manner even in complex environments.

[0105] When a valid manual intervention signal is received, an audible and visual warning termination instruction is immediately sent to the timed-out device door smart lock.

[0106] If the timeout state continues until the preset sound and light warning period ends and no manual intervention signal is received, a warning upgrade mark is generated and the current sound and light warning is stopped.

[0107] Through strong visual and auditory prompts, it can quickly attract the attention of nearby staff, make them aware of the current abnormal situation, and promptly remind relevant personnel to take action to prevent further expansion of safety hazards caused by negligence or failure to notice the problem.

[0108] Specifically, the specific implementation process of the remote alarm is as follows: when the timeout status mark of the target device door smart lock is detected and the warning upgrade mark is received, a remote alarm signal start instruction is generated.

[0109] Parse the unique identifier of the operation task in the current electronic operation ticket and the physical location code of the target device door smart lock.

[0110] It should be noted that parsing the unique identifier of the operation task in the current electronic operation ticket and the physical location code of the target device door smart lock can help accurately locate the problem in a complex environment.

[0111] Construct a structured alarm data packet containing the unique identifier of the operation task, the physical location code of the timed-out device, the timeout start point, and the current alarm level.

[0112] Send remote alarm signals to the preset power dispatching system monitoring center and authorized operator terminals through encrypted communication channels.

[0113] Monitor the opening status of the equipment door and the input status of the manual intervention signal, and generate a remote alarm termination instruction when a valid manual intervention signal is received.

[0114] Send a remote alarm termination signal to the power dispatching system monitoring center and authorized operator terminals.

[0115] It should be noted that when local audible and visual warnings are not enough to resolve the problem, remote alarm signals can notify a wider emergency response team, including technical support or management personnel who are not on site, so that they can take further action quickly.

[0116] Through the phased timeout graded response mechanism, operators can be effectively guided to pay attention to and solve existing problems without affecting normal work, ensuring the safe and stable operation of the facilities.

[0117] The safety lock execution module is used for automatically forcibly locking the timed-out device door lock that is currently in the open state when no manual intervention signal is received after the timeout and the operation time limit countdown is exhausted.

[0118] Specifically, a forced locking instruction is generated when it is detected that the target device door smart lock simultaneously meets the conditions of having a timeout status mark, receiving an alarm upgrade mark, no manual intervention signal after a remote alarm, and the operation time limit countdown is exhausted.

[0119] Extract the physical location code of the current target device door smart lock, send a forced locking instruction to the target device door smart lock through an encrypted communication channel, and trigger the electric locking device of the device door lock mechanism to perform a forced locking action.

[0120] Monitor the locking status signal of the target device door in real time, and generate a locking completion confirmation instruction after confirming that the locking is in place.

[0121] Update the locking completion status mark to the corresponding operation progress record of the electronic operation ticket.

[0122] It's important to note that timely locking helps protect equipment from environmental influences such as dust and humidity, while also preventing potential safety hazards caused by prolonged exposure. When automatic locking occurs, the lock can simultaneously transmit relevant information to the central monitoring system, allowing managers to promptly understand on-site conditions and make appropriate decisions, thereby ensuring the safe and stable operation of the facility.
