Description

Technical Field

[0001] The present invention relates to the technical field of hydropower station operation and maintenance, and in particular to a hydropower station maintenance standardized operation guidance system and a hydropower station maintenance standardized operation guidance method. Background Art

[0002] With the large-scale development of hydropower stations and the increasing demand for digital management, the maintenance work of hydropower stations is gradually moving towards standardization and informatization. However, since hydropower station maintenance operations involve a wide variety of equipment, complex processes, and clear division of labor, the existing maintenance solutions still face many technical difficulties in practical application.

[0003] The current maintenance management of hydropower stations usually relies on manual preparation of maintenance plans and maintenance documents, which can easily lead to problems such as inaccurate plans, untimely information updates, and irregular data management. For example, the preparation of maintenance notices, work instructions, and maintenance reports is mostly manually entered, lacking effective standardized template support, and the data between documents cannot be automatically associated, resulting in a large workload of repeated entry and a high error rate. In addition, the management and sharing of defect data has not been centralized, and the historical processing information of equipment defects is difficult to trace, affecting the efficiency and quality of defect handling.

[0004] In the actual maintenance process, due to the complex operating environment, the real-time data entry and offline data synchronization mechanism has not been fully established, making it difficult to ensure the integrity and consistency of the operating data. Data verification and recording during the maintenance process rely on manual inspection, which is prone to omissions or inaccuracies, directly affecting the quality of maintenance. On the other hand, the management and replacement planning of wearing parts lack an effective life cycle tracking mechanism, resulting in insufficient spare parts or excess inventory, increasing operating costs and maintenance risks.

[0005] In addition, the existing system has limited capabilities in data analysis and display, lacks large-screen visualization and mobile terminal functions, and cannot meet the needs of real-time monitoring, statistical query and mobile office. This makes it difficult for managers to understand the progress of maintenance in a timely manner, delays decision-making, and affects overall work efficiency.

[0006] In summary, the existing hydropower station maintenance management solutions have deficiencies in data standardization, process automation, defect sharing and wearing parts management, and cannot effectively support complex maintenance tasks. Therefore, a new maintenance system based on standardized templates, automated processes and full life cycle management is urgently needed to improve the efficiency and quality of hydropower station maintenance work.

After filling in, the data will be automatically synchronized to the system background, reducing the duplication of manual records and later data entry. When the device signal is poor, the mobile terminal supports offline data storage, and automatically uploads it after the network is restored to ensure the integrity of the operation data. The mobile terminal provides powerful data viewing functions, and users can access the equipment defect library, maintenance progress and historical data online at any time. The defect library supports keyword search and filtering, and users can quickly find equipment defect records and processing suggestions; the maintenance progress shows the execution status of the current task, including the completion ratio and key node information; the historical data module allows users to view maintenance records over the years to provide a reference for the current task. All data are presented in a structured manner for quick review and decision-making.

[0066] Figure 2 This is a method flow chart of a method for guiding the maintenance of a hydropower station in a standardized manner provided by an embodiment of the present invention. Figure 2 As shown, an embodiment of the present invention provides a method for guiding standardized maintenance operations of a hydropower station, the method comprising:

[0067] Step S10: Verify user permissions based on the RBAC model, and call the corresponding standardized template based on user needs after the verification is passed.

[0068] Specifically, the user permissions are verified based on the RBAC (role-based access control) model, and after the permissions are verified, the corresponding standardized template is called according to the user's needs, providing a reliable guarantee for the safety and efficiency of the hydropower station maintenance operations. The RBAC model ensures that different users can only access functions and data within their responsibilities through role allocation and permission management, effectively preventing unauthorized access and operation.

[0069] Specifically, each user is assigned a role, and the corresponding permission set is defined based on the role. For example, managers can call maintenance report templates and approve key tasks, while ordinary maintenance personnel can only edit work instructions or fill out technical record cards. After the user logs in, the RBAC model dynamically assigns permissions based on their roles to ensure that users can access modules and data that match their responsibilities while blocking irrelevant content. After the permission verification is passed, the relevant standardized templates are automatically called according to user needs. These templates include maintenance notice templates, work instruction templates, and maintenance report templates, which predefine the data structure, task flow, and record format in maintenance operations to ensure the standardization and uniformity of maintenance tasks. Users can directly load the template and start filling it out, avoiding the complexity of designing templates from scratch and improving operational efficiency. In addition, it supports version management of templates, and automatically matches the latest version when calling to ensure that the content meets the current maintenance standards.

[0070] Step S20: Generate a maintenance plan based on the standardized template in combination with historical records and planning rules, and initialize the maintenance notice and task data.

[0071] Specifically, based on standardized templates, combined with historical records and planning rules, maintenance plans are automatically generated, and maintenance notices and task data are initialized, providing an efficient and standardized plan generation method for hydropower station maintenance operations. This function significantly improves the efficiency of maintenance plan preparation and the standardization of task management through data integration and intelligent operation.

[0072] Specifically, the standardized templates in predefine the key information required for maintenance tasks, including equipment name, maintenance category, time node and necessary resource requirements. After the user calls the template, there is no need to manually enter a large amount of repetitive data, and directly fill in the established format to provide a basic framework for subsequent plan generation. The template also supports dynamic adjustment. According to the special needs of the maintenance task, the user can flexibly modify the template content and save it as a new version. Extract relevant data from historical maintenance records, and automatically generate a scientific and reasonable maintenance plan in combination with the set planning rules (such as unit maintenance cycle, defect repair priority, etc.). For example, prioritize the maintenance tasks of important equipment according to historical defect processing data, or dynamically adjust the maintenance cycle according to the equipment operation time and status. At the same time, the planning rules can be customized by users, including maintenance intervals, resource allocation standards, etc., to meet the business needs of different power plants.

[0073] Furthermore, after the maintenance plan is generated, the maintenance notice is automatically initialized, and the task data such as equipment name, maintenance item, and planned time are filled into the notice to form a task file that can be directly distributed. In addition, it supports docking with ERP, automatically pulls equipment defect data and associates it with the notice to ensure the comprehensiveness and accuracy of the maintenance task.

[0074] Step S30: Generate a work instruction based on the notification sheet, and verify and standardize the input data in real time.

[0075] Specifically, the operation instructions are automatically generated according to the maintenance notice, and the user input data is standardized through the real-time verification function to ensure the accuracy and executability of the operation instructions. This function runs through the core execution links of the maintenance task, realizes standardized management from task decomposition to specific operations, and significantly improves the efficiency and quality of hydropower station maintenance operations.

[0076] Furthermore, based on the maintenance notice, the work instructions are automatically initialized through standardized templates, including modules such as task decomposition, tool list, quality control planning, and technical record cards. Users do not need to write complex documents from scratch. According to the maintenance items and equipment requirements, the task content is automatically filled into the instructions according to the chapter structure. For example, the key tasks, standard maintenance items, and safety inspection contents of equipment maintenance will be clearly listed in the instructions, providing clear operation guidance for on-site operators.

[0077] To ensure the standardization of data input, a real-time verification function is provided during the filling process of the work instructions. When the user enters data, abnormal data is automatically detected and corrections are prompted according to preset rules (such as numerical range, format standard, logical conditions, etc.). For example, for the input of equipment parameters, the values ​​that exceed the reasonable range are marked to avoid human errors affecting the maintenance results. The data verification function not only improves the accuracy of the operation data, but also simplifies the process of manual review. On the basis of automatic generation, users are allowed to flexibly edit the work instructions according to actual needs. Users can adjust the task content, add supplementary information or modify standard items, and view the final format through the real-time preview function to ensure that the instructions meet expectations.

[0078] Step S40: Record the maintenance process data and automatically generate a complete maintenance report and acceptance results.

[0079] Specifically, by recording maintenance process data and automatically generating complete maintenance reports and acceptance results, an efficient and standardized maintenance task summary and feedback mechanism is provided. This function runs through the entire process of hydropower station maintenance operations, from data collection to results output, ensuring the integrity, accuracy and traceability of maintenance information, and providing a reliable basis for subsequent maintenance work.

[0080] Specifically, key data is recorded in real time during the maintenance operation, including task execution progress, equipment status changes, tools used, and materials consumed. Maintenance personnel enter maintenance data online through the work instruction module, or save the data offline when the network is unstable, and automatically upload it after the connection is restored. This real-time data recording mechanism ensures the comprehensiveness of task execution and reduces omissions and errors caused by manual recording.

[0081] After the maintenance task is completed, a complete maintenance report is automatically generated by integrating the maintenance notice, work instructions and process record data. The report content includes the comparison between the planned construction period and the actual construction period, the results of the treatment of equipment defects, the completion of key tasks, the details of consumables usage, and the performance evaluation of the equipment after maintenance. It also supports the automatic embedding of acceptance cards and key node witness content into the report to form a comprehensive document with a clear structure and detailed content. The acceptance results are generated based on the recorded maintenance data and acceptance process, including the completion status of each task node, the reasons for unfinished projects and subsequent plans. The acceptance results are automatically linked to the maintenance report to form a complete closed-loop operation to ensure that the maintenance work results are transparent and traceable.

[0082] Step S50: Storing the maintenance data in the knowledge base and linking it with the management of wearing parts to complete life cycle warning and update.

[0083] Specifically, by storing maintenance data in the knowledge base and linking it with the consumable parts management module, intelligent management of equipment maintenance information and dynamic tracking and optimization of the consumable parts life cycle are achieved. This function closely combines the accumulation and utilization of maintenance data with the life cycle management of consumable parts, improving the knowledge accumulation ability and planning of equipment maintenance.

[0084] Furthermore, after the maintenance task is completed, key data such as maintenance reports, equipment status changes, and defect handling records are stored in the knowledge base. The knowledge base classifies and archives the data and supports multi-dimensional retrieval, such as filtering by equipment category, defect type, or time range. Through the centralized management of the knowledge base, users can quickly obtain historical maintenance data to provide reference for subsequent maintenance tasks. In addition, the knowledge base is supported to dynamically update to ensure the real-time and accuracy of the data.

[0085] The knowledge base is linked with the consumable parts management module to automatically associate the consumable parts usage and replacement records recorded during the maintenance process with the consumable parts lifecycle management. By analyzing the historical replacement data of consumable parts, their remaining life and the next replacement time are dynamically updated. At the same time, the module is combined with the inventory management function to monitor the inventory status in real time to ensure the adequacy of spare parts. When the consumable parts are about to reach the end of their service life or the inventory is below the threshold, an early warning reminder is issued to help users plan replacement and procurement in advance. Combining maintenance data and consumable parts management, a complete lifecycle early warning and update mechanism has been established. By automatically analyzing the operating data and historical maintenance records of consumable parts, it is possible to predict the possible failure time, generate replacement suggestions, and automatically add the replacement task to the next maintenance plan to ensure the continuity and reliability of equipment operation.
