Description

Technical Field

[0001] The present invention relates to the technical field of power plant isolation and lockout management, and in particular to a power plant isolation and lockout digital management method for authority control. Background Art

[0002] At present, the problem of lock and key management is becoming increasingly prominent in the operation and maintenance of power generation enterprises, becoming a major bottleneck affecting work efficiency and safety management. Traditionally, the number and types of locks and corresponding keys equipped for various equipment and facilities are large and complex, which greatly increases the workload of staff. Especially in the case of urgent need for emergency repairs or inspections, finding the correct key is often time-consuming and laborious, which seriously affects the response speed and work efficiency.

[0003] In addition, this traditional key management model also has a series of potential safety hazards. On the one hand, due to the lack of high-tech support, keys are easily lost or stolen, and once a safety accident occurs, it is difficult to trace the responsibility; on the other hand, the phenomenon of opening and locking the wrong keys due to human error is also difficult to avoid, which increases unnecessary risks and may even endanger production safety and personal life and property safety in serious cases.

[0004] In order to solve these problems, it is imperative to introduce passive locks, smart keys and intelligent management systems. The intelligent management system uses smart lock solutions based on Internet of Things technology to achieve accurate management of keys, such as RFID (radio frequency identification), NFC (near field communication) or Bluetooth technology. Combined with a digital management platform, it can remotely monitor the use of each key to ensure authorized access, while providing detailed records and audit trails, greatly improving security and traceability. In addition, by integrating artificial intelligence algorithm predictive analysis, the system can also optimize the key distribution process, reduce manual intervention, and further improve work efficiency.

[0005] To sum up, power generation companies urgently need to use modern scientific and technological means to innovate the key management system in order to eliminate safety hazards, improve overall operational efficiency, and ensure safe production.

[0006] The isolation and lockout digital management platform is an online platform designed to help power plant companies manage locks and keys more effectively. It can also provide risk warning and automated management and control. By providing an intelligent and centralized digital environment, it makes power plant isolation lock key management more efficient and intelligent, reduces human errors, and thus avoids safety hazards. Summary of the invention

[0007] The purpose of the present invention is to solve the shortcomings of the prior art and propose a digital management method for power plant isolation lock based on authority control. The method mainly includes a passive lock, a smart key and a power plant isolation lock digital management platform.

[0008] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: using intelligent passive locks as the main equipment for on-site isolation and locking, integrating them with the power plant work ticket and operation ticket system through a digital management platform, realizing the authority control of isolation and locking, and having an intelligent control visualization system interface, which can clearly reflect the status of on-site isolation and locking, and facilitate real-time management.

[0009] The intelligent passive lock combines the characteristics of mechanical lock and electronic lock, and is composed of a lock body and a lock core. The passive lock body has no power supply and needs to be equipped with an electronic lock core.

[0010] When the electronic lock cylinder needs the smart electronic key to be inserted into the electronic lock cylinder, the electronic key is used to power the passive lock cylinder and perform dynamic key verification. After the verification is passed, the lock can be opened. The passive lock has a unique ID and can also store the lock switch record and associate it with the platform database.

[0011] As a further solution of the present invention: the intelligent two-ticket and passive lock system integration framework includes terminal devices such as passive locks, intelligent electronic keys, and a smart two-ticket and passive lock data management background subsystem.

[0012] The architecture of the intelligent "two tickets" (work ticket and operation ticket) and passive lock data management background subsystem usually covers the following main parts, which together constitute an efficient and secure data management and execution process: user management module, intelligent work ticket management, passive lock integration, real-time monitoring and alarm function module.

[0013] The account creation and permission setting described above: create files for users at all levels, including ordinary employees, technicians, administrators, etc., and grant different operating permissions according to their functions.

[0014] The intelligent work ticket management process includes filling out work tickets, approval, review, implementation of safety measures, supplementation of safety measures, work permits, changes in work supervisors, work ticket extensions, work interruptions and transfers, and completion of work, among other process node scenarios.

[0015] Filling in the work ticket: There is no restriction on the authority of operation and maintenance personnel, and the isolation key box (or virtual key box) number is allocated. According to the nature of the work, the work ticket issuer and the work supervisor shall fill in the work supervisor, specific work content, work scope, isolation key box status, department, team, person filling out the ticket, date of filling out the ticket and other information on the corresponding type of work ticket and submit it to the system.

[0016] The issuance: The operation value is long, and the issuer can return to the original state, modify and reissue. Authorize the smart electronic key through the work ticket system.

[0017] The implementation of safety measures: the implementation of measures, thermal control, relay protection dual implementation, isolation key collection in isolation key box (or virtual collection). The implementation of the person using the intelligent electronic key and passive lock to isolate the on-site equipment.

[0018] Supplement to the safety measures mentioned: “Supplementary safety measures” column of the permit holder or person in charge of the work.

[0019] The work permit: the work permit issuer, work supervisor, and project supervisor confirm through handling-review-authorization. The system generates a security key number to the work ticket according to the key box number + ABC-- (one key box can be associated with multiple work tickets), and hands the security key to the (authorized) work supervisor.

[0020] The aforementioned change in the person in charge of the work: the role change of the original person in charge of the work, the new person in charge of the work, and the person who authorizes the work will be set up and changed by the system's super administrator and some ordinary administrators, and the system settings will be completed through the process of handling and authorization.

[0021] Extension of the work ticket: The work permit holder and the work supervisor can only extend it once, which is set by the system.

[0022] The work interruption and transfer mentioned include: ticket inspection and trial operation, work permit holder and work supervisor.

[0023] The work is completed: the work permit holder and the work supervisor confirm the authorization, the work supervisor hands over the safety key to the work permit holder (or the safety lock is opened after authorization by the work supervisor), all safety locks of the isolation box are opened (all work tickets are completed), the work permit holder authorizes to open the control lock, all isolation keys in the key box can be taken out (activated), the on-site isolation lock can be opened, and the safety measures can be lifted.

[0024] The release of safety measures: taking out (activating) the key from the key box, opening the on-site isolation lock, releasing the safety measures, and the person executing the measures authorizing and confirming.

[0025] The work ticket ends: the licensee authorizes and confirms the status change.

[0026] The passive lock integration includes device identification and location management, and dynamic key distribution. The device identification and location management assigns a unique code to each lock to ensure that it can be accurately located and tracked in the network. The dynamic key distribution: combined with biometrics or other security authentication mechanisms, it can achieve real-time decryption and door opening, adding an extra layer of protection.

[0027] Real-time monitoring and warning: Status monitoring: continuously collect lock status information, such as whether it is activated, user identity, usage time, etc. Abnormal behavior warning: when unauthorized operation or trend is detected, the warning is immediately activated to ensure timely response.

[0028] As a further solution of the present invention: the intelligent passive lock is used as the main equipment for on-site isolation and locking, and is integrated with the power plant work ticket and operation ticket system through a digital management platform. The digital management platform refers to the front-end graphic management application system. The front-end graphic management application system realizes the front-end processing and display of the intelligent management data of the equipment.

[0029] The front-end processing and display of the intelligent management data of the equipment is the data processing and display of the following key modules to ensure its comprehensive functional coverage and efficient operation: user authority management module, smart lock control device interface, workflow engine, real-time monitoring and alarm system, data analysis and reporting tools, mobile application client, training and education database.

[0030] The user rights management module is responsible for defining and assigning different levels of user roles and their related rights, including work leaders, work permit holders, project leaders, etc., to ensure that each person can only access resources within their scope of responsibility. Different roles are identified by different icons.

[0031] The smart lock control device interface is connected to various locks and keys with smart chips to achieve remote control and status monitoring, support multiple verification methods such as biometrics, and ensure safe access and operation of the device. The biometrics mainly include fingerprint recognition.

[0032] The workflow engine module automatically processes isolation and lockout requests, seamlessly connecting the entire process from application to approval and final implementation to ensure operational standardization and compliance.

[0033] The real-time monitoring and alarm system monitors the lock status changes around the clock and sends an alarm immediately once abnormal activities are detected, such as illegal opening attempts or long-term failure to restore the lock status. The system also prompts the user through an early warning pop-up window.

[0034] The data analysis and reporting tool collects the operation logs of the work leaders to form a detailed audit trail, supports customized report output, and assists management in gaining insight into trends and identifying problems in a timely manner.

[0035] The mobile application client provides a convenient interface for front-line employees, allowing them to quickly respond to notifications and complete work tasks no matter where they are, thereby improving flexibility and response speed.

[0036] The training and education database stores teaching materials on standard operating procedures and safety guidelines. The front end supports report generation and downloading to promote employee self-learning and improve the overall quality of the team.

[0037] Compared with the prior art, the advantages and positive effects of the present invention are:

[0038] In the present invention, by using the front-end digital management platform, connecting the intelligent passive lock, intelligent electronic key hardware equipment and the background system, the platform can process and display the background data. This innovative isolation and locking management system deeply fits the core needs of power generation enterprises for safe production, cleverly integrates the intelligent "technical defense" elements, and significantly improves the digital safety management level of operations through mandatory safety measures, real-time monitoring and early warning, automated process optimization and data-driven decision-making. The system can not only effectively avoid equipment damage and casualties, but also significantly speed up the progress of work and reduce the probability of errors, thereby building a safer and more efficient production environment that integrates the front-end, back-end and intelligent hardware. In addition, the educational resources contained in it further consolidate safety awareness, cultivate professional skills, and create a solid safety net in all directions. In view of this, this system has shown excellent market application prospects, leading the power industry towards intelligence and standardization, and injecting strong momentum into the safety upgrade of the global energy industry.

[0045] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0046] Embodiment 1

[0047] See also Figure 1 ,The architecture of a power plant isolation and lockout management method based on ,authority control is composed of three parts: an intelligent control ,integrated digital display module, a data management module, and intelligent hardware.

[0048] The data management module captures data from online platforms such as corporate public data and social media platforms and names it as raw data;

[0049] By applying supervised learning, unsupervised learning, reinforcement learning and other algorithm models through big data analysis technology, we can learn rules from the company's historical data and then predict future situations. This helps to make forward-looking judgments and decisions based on data.

[0050] The data management module uses the background management function to centrally manage the permissions of locks and electronic keys, and conducts real-time monitoring and early warning of data information such as lock status and smart double tickets.

[0051] Smart two tickets: including smart work tickets and smart operation tickets, realizing two-ticket management and two-ticket basic configuration functions; also integrated into the data management module.

[0052] Firstly, smart work tickets include electronic application and approval: paper is abandoned and the entire work ticket process is electronic, including creation, review, approval, distribution, closure and other steps, which simplifies the process and reduces errors and delays.

[0053] Task allocation and tracking: Automatically match work teams and tasks, track work progress in real time, ensure that each task has a dedicated person in charge, and improve responsibility clarity and execution.

[0054] Self-check of safety conditions: The system presets safety standards based on the work content and automatically generates a list of safety measures to be followed to prevent omissions and ensure adequate preparation before work.

[0055] Integrated training and examinations: Built-in online learning modules provide relevant safety knowledge teaching. Employees must pass the assessment before they can receive a work ticket, strengthening their safety awareness and skills.

[0056] The second is smart operation tickets and standardized operation steps: define a detailed set of operation processes, execute them step by step, reduce discretion, and ensure that each operation is consistent and compliant.

[0057] Real-time verification and recording: Every action during the operation is automatically recorded by the system, and any deviation will be immediately prompted to ensure that each step is accurate.

[0058] Intelligent decision-making support: The system recommends the best operation sequence based on the current working conditions, assists the operator in selecting the best solution, improves efficiency and reduces risks.

[0059] Fault emergency response: Integrated emergency plan, when the system detects an abnormality, it will be activated immediately to guide the operator how to handle the emergency safely and quickly.

[0060] Therefore, the data management module captures the historical record data of the smart double ticket and processes it in the same way as above;

[0061] Smart hardware includes passive locks, smart keys, and mobile phones: all use electronic and mechanical dual encryption technology, combined with background management systems and mobile phone APPs to achieve operation.

[0062] Passive locks combine the characteristics of mechanical locks and electronic locks, and are composed of a lock body and a lock core. Passive means that the lock body has no power supply and is equipped with an electronic lock core. When the smart electronic key is inserted into the electronic lock core, the passive lock core is powered by the electronic key and a dynamic key verification is performed. After the verification is passed, the lock can be opened. Each passive lock has a unique ID and can also store lock opening and closing records. With three-level password authority management + dynamic key, it can prevent copying, technical unlocking, and magnetic unlocking, and has good security and reliability.

[0063] Smart electronic key: As the management core of the smart lock system, the smart electronic key is responsible for recording the staff's usage information, the location of the lock, and the time of the lock. The electronic key has added Bluetooth transmission function in the design, which can be connected to the mobile phone to realize remote authorization to unlock. It also has a fingerprint recognition function to determine the identity of the person who opens and closes the lock, so that the responsibility is assigned to the person. It has a voice prompt function, which can help users quickly obtain the working status of the electronic key. The charging and communication of the electronic key adopt the standard TYPE-C interface, which is simple and convenient.

[0064] Mobile phone: Communicates with the smart electronic key via Bluetooth to collect the status and switch information of the electronic key and lock. You can also manage the permissions of the smart electronic key and set the key for each task through the mobile APP. The smart key can correspond to multiple passive locks according to different work ticket instructions.

[0065] The intelligent management and control integrated digital display module, as the core component of this method, aims to transform the complex and multi-dimensional data of the data management module into an intuitive and easy-to-understand visual form, so that decision makers at all levels can obtain key information in a timely manner and make accurate decisions.

[0066] The digital display module is based on the data integration results, calls the data in the background database, designs the structure and content of the chart, combines the front-end frameworks including Vue.js and React, builds the user interface and interaction, uses Vue components to draw reports, and integrates with the JavaScript framework to create charts and information visualization of power plant keys.

[0067] Specifically, it includes centralized data aggregation: integrating various data sources (such as ERP, CRM, SCM, etc.) to form a unified data view, eliminate information islands, and ensure data consistency and integrity.

[0068] Personalized dashboard: Provides flexible interface setting options, allowing each user to adjust the layout, color, chart type, etc. according to their needs to create a display style that suits their personal habits.

[0069] See also Figure 2 , work ticket and passive lock management flow chart, the roles are divided into work supervisor, work permit holder, work ticket issuer, and work ticket approver.

[0070] The person in charge of the work fills in the work ticket information and uploads it to the work approver through the system to review whether the safety measures are complete. Once complete, the work issuer will issue the work ticket and optionally generate a virtual key box.

[0071] After the work auditor has reviewed the work ticket and found no problems, he or she will authorize the keys and locks, and the work permit issuer will carry out on-site security measures and execute the instructions.

[0072] The person in charge of the work will carry out specific on-site operations and apply to release the wrong key after the work is completed.

[0073] See also Figure 3 , application structure design. The roles are divided into users, Bluetooth keys, two-ticket APPs, and passive locks.

[0074] Users can directly turn on the Bluetooth function of the key or search for the key through the Bluetooth function of the APP. Users can select the corresponding key in the list according to their needs.

[0075] The user then applies to call the key of the passive lock through the APP and receives the key instruction.

[0076] Next, the user applies for the authorized person's information through the APP and receives the fingerprint ID of the authorized person returned.

[0077] In the next step, the user connects the Bluetooth key through the fingerprint ID array. After the key is verified, the key person authorizes and waits for the callback to return the result.

[0078] The user executes the security measure, obtains the authorization lock information through the APP, and receives the authorization lock array returned by the passive lock.

[0079] The user authorizes the smart key to unlock the door through the APP, and receives the unlock result information returned by the Bluetooth key. At the same time, the unlock data is uploaded to the passive lock.

[0080] Users clear key records and key authorization records through the APP

[0081] After the user completes the security measures, the user can obtain the lock information associated with the work ticket through the APP

[0082] At this time, disconnect the Bluetooth connection of the smart key.

[0083] See also Figure 4 ,The core function design of the virtual key box, the system provides a virtual key box query function. By clicking the virtual key box number, you can trace the passive lock number corresponding to the key in the key box, as well as the isolation device number and name of the lock.

[0084] Each key box has a corresponding virtual number, which shows the current data to the customer, including the number of keys, the number of keys currently occupied, and the number of keys idle.

[0085] Click on each key box to see the detailed information, including the device information corresponding to each key, device name, passive lock number, whether the current account has permission to use and other data tags. The matching result generation ensures the visualization and clarity of the final matching result. This will improve the matching accuracy, efficiency and user experience of lock and key devices.

[0086] See also Figure 5 If the system detects that the maintenance personnel violated the safety work regulations and did not work according to the work ticket, or there was a tendency to work in violation of the process, the system would issue a risk warning in advance, and the smart key would beep, prompting the maintenance personnel to stop their work in time and leave the site. At the same time, a red warning color and prompts appeared on the system interface, the background automation mode was started, the connection was forced to close the isolation lock, and the work ticket was taken back.

[0087] See also Figure 6 , through the combination of system software and electronic keys, authorized unlocking and remote unlocking are realized, and unlocking and locking data are recorded. The name, isolation time, and isolation key number of the isolated person can be recorded in real time, and uploaded to the work ticket system, reducing the workload of isolated personnel to record manually and enter the computer. The manager can clearly query who opened which lock and at what time, and ensure that the on-site locks are in a closed state. Applicable to multiple scenarios: For scenarios where there are cross-security measures between work tickets, authorization can be used to solve the actual need to open a lock together according to the cross-security management and control requirements.

[0088] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the scope of implementation of the technical solution of the present invention.
