[0002] The secondary switch cabinets in power plants are important equipment in the power system. They contain various control, protection, measurement and other devices, which play a key role in the safe and stable operation of power plants. Once the equipment in the secondary switch cabinets is subject to illegal operation, misoperation or unauthorized access, it may lead to misoperation of protection, equipment damage or even power system faults, affecting the normal operation of the entire power plant, and thus posing a serious threat to the power supply reliability and stability of the power grid. Therefore, it is crucial to ensure the safe access and operation management of secondary switch cabinets.

[0003] Traditional locks for secondary switch cabinets in power plants are mostly mechanical locks with mechanical keyholes. This design makes the switch cabinets vulnerable to illegal intrusion such as lock picking. Once the mechanical keys are lost or copied, it will directly threaten the safety of the equipment in the switch cabinets and affect the stable operation of the power system. In addition, the previous authorization management lacked effective technical means and mainly relied on manual records and paper work tickets. The process was cumbersome and prone to errors. During actual operation and maintenance, it was difficult for operation and maintenance personnel to quickly determine their authorized scope and operable equipment, and there were often permission confusions, resulting in low work efficiency. Moreover, the management of operation and maintenance records was also relatively scattered, which was not convenient for querying and statistics, and it was impossible to timely discover potential safety risks and operation and maintenance problems.

[0004] Therefore, corresponding technical solutions need to be designed to solve this problem. Summary of the Invention

[0034] According to the above description, further elaborated, the edge computing node integrates a local policy engine, performs real-time analysis on the lock status data based on preset rules, triggers local audible and visual alarms, and uploads abnormal event data to the cloud.

[0035] According to the above description, further elaborated, the zero-trust cloud management and control platform includes:

[0036] Work ticket linkage module: automatically generating a one-time encrypted key according to the operation content, associating the operator, time, and switch cabinet location, and realizing a full-process closed loop of "issuing a ticket - authorizing - canceling a ticket".

[0037] Big data analysis engine: identifying high-frequency abnormal locks and security risk trends based on historical operation records, and generating operation and maintenance optimization strategies.

[0038] Blockchain storage system: making an immutable record of authorization records, operation logs, and abnormal handling results, and supporting full-process traceability.

[0039] Based on the above description, it is further elaborated that the mobile application supports dynamic authorization interaction: obtain the current location through positioning, display the list of switch cabinets within the authorized range, send the authorization key to the intelligent lock through NFC / RFID, and support multi-level approval and time / number limit for temporary authorization of external personnel.

[0040] Based on the above description, it is further elaborated that it includes the following steps:

[0041] S1. Status collection and encrypted transmission: The intelligent lock collects the position, vibration, and pressure data of the lock tongue in real time through sensors, and transmits it to the edge computing node after being processed by the encrypted communication chip;

[0042] S2. Hierarchical authorization verification: The cloud platform generates a dynamic authorization key according to the work ticket and synchronizes it to the mobile terminal / edge node. The operation and maintenance personnel send the key through the mobile terminal, the lock locally verifies the legitimacy, and the edge node synchronously verifies the matching of the operation time and the device;

[0043] S3. Abnormal early warning and linkage response: The edge node identifies primary abnormalities (such as continuous incorrect unlocking) and triggers a local alarm. The cloud platform combines personnel permissions and historical records for AI risk judgment and generates hierarchical early warnings (level 1 pop-up window / level 2 SMS / level 3 security linkage);

[0044] S4. Data evidence storage and closed-loop management: Operation logs, authorization records, and abnormal handling results are stored as evidence through the blockchain, supporting full-process traceability. After the operation is completed, the authorization certificate automatically expires.

[0045] Working principle: For the computing and control system of the non-hole and non-power intelligent lock for the secondary switch cabinets of this power plant, during use, the non-hole and non-power intelligent lock is installed on the door of the secondary switch cabinet, and non-contact power supply is realized through the wireless induction power supply module without external power supply. The lock integrates a lock tongue position sensor, a vibration sensor, and a national secret algorithm encrypted communication chip to complete the hardware initialization;

[0046] The zero-trust cloud control platform is connected to the power plant work ticket system, presets basic data such as personnel permissions, device IDs, and switch cabinet positions based on the RBAC (Role-Based Access Control) model, and at the same time configures the local policy engine rules of the edge computing node (such as the threshold for the number of continuous incorrect unlocking times, the vibration intensity early warning value, etc.), and defines the hierarchical early warning response mechanism (level 1 pop-up window, level 2 SMS, level 3 security linkage);

[0047] The operation and maintenance personnel initiate a work application through the power plant system and generate a work ticket containing the operator, operation time, and the location of the cabinet involved. The work ticket linkage module of the cloud platform automatically associates the work ticket information and generates a one-time dynamic authorization key containing a timestamp, device ID, and permission range. The cloud platform synchronizes the authorization key to the corresponding edge computing node and mobile application through industrial Ethernet to ensure that the authorization information is updated in real time.

[0048] The operation and maintenance personnel perform identity authentication (such as account password, biometrics) through the mobile terminal to obtain the current positioning information. The mobile terminal displays the list of operable cabinets according to the positioning and authorization scope (only displays the devices within the authorization scope). When the operation and maintenance personnel select the target cabinet, they send the authorization key to the smart lock through NFC / RFID. The smart lock locally verifies the legitimacy of the key (encrypted communication chip decryption verification). At the same time, the edge computing node synchronously verifies the matching of the operation time, device ID and authorization scope. When the verification passes, the electromagnetic drive motor of the lock controls the extension and retraction of the lock tongue to complete the unlocking and record the operation log (time, personnel, device ID). When the verification fails, the edge node triggers a local sound and light alarm and uploads abnormal events (such as "illegal unlocking attempt") to the cloud.

[0049] Smart locks collect the lock tongue position (unlocked / locked status), vibration data and pressure data in real time. After being processed by the encrypted communication chip, they are transmitted to the edge computing node through wireless / wired communication. The edge computing node analyzes the data based on preset rules and identifies primary anomalies, such as three consecutive incorrect unlockings and continuous vibration exceeding the threshold. It immediately triggers the local sound and light alarm and uploads the abnormal data to the cloud. The cloud platform combines personnel permissions, historical operation records and real-time data to conduct risk assessment through AI algorithms, such as determining whether it is an illegal intrusion by outsiders;

[0050] And generate graded warnings: Level 1 abnormality (minor): a pop-up window on the mobile terminal reminds the operation and maintenance personnel;

[0051] Level 2 anomaly (moderate): SMS notification to department head with details of the anomaly;

[0052] Level 3 abnormality (serious): The security system is linked to trigger camera capture, surrounding access control is locked, and the safety warning of the whole plant is initiated;

[0053] After the operation is completed, the cloud platform automatically marks the work ticket as "completed", and the associated authorization key becomes invalid immediately and cannot be used to unlock the door later. The blockchain evidence storage system stores authorization records, operation logs, and exception processing results in an unalterable manner, and supports full-process traceability queries to meet security audit requirements.

[0054] The cloud-based big data analysis engine identifies high-frequency abnormal locks based on historical data and generates operation and maintenance recommendations, thereby promoting preventive maintenance.
