Description

Technical Field

[0001] This invention belongs to the field of hydropower engineering construction technology, specifically relating to a quality evaluation and management method and system for pumped storage power stations. Background Technology

[0002] Existing quality assessment and management systems for pumped storage power stations largely rely on manual operations. Form templates are inconsistent and lack reusability. There is a lack of unified standards for project division and quality control point configuration, requiring manual form filling, approval, and archiving, which is inefficient and prone to data discrepancies. Furthermore, existing systems often lack deep integration between quality assessment and 3D models, making it impossible to intuitively display quality status. Moreover, each module is developed independently, lacking underlying data linkage, resulting in low technical barriers and insufficient innovation, making it difficult to meet the refined, automated, and visualized management requirements for quality assessment and management of pumped storage power stations.

[0003] In view of this, the present invention is hereby proposed. Summary of the Invention

[0004] To address the aforementioned technical problems in the existing technology, this invention provides a quality inspection and management method and system for pumped storage power stations, which solves the problems of inconsistent quality inspection and evaluation templates, cumbersome control point configuration, low efficiency in form filling and approval, insufficient visualization of quality status, lack of underlying linkage between modules, and insufficient technological innovation in the existing technology.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: Firstly, a quality assessment and management method for pumped storage power stations includes: A layered modular architecture is constructed, comprising a data layer, a business logic layer, and a presentation layer. Each layer communicates with each other through standardized interfaces. The data layer uses MySQL to store structured data and Redis for caching optimization. Establish a quality inspection and evaluation standard library, realize standardized management of multi-format form templates through a custom template parsing engine, construct a hierarchical model of engineering types, and realize batch association between control points and form templates through a batch configuration algorithm for control points; Based on the aforementioned quality inspection and evaluation standard library, the entire process of quality inspection and evaluation is managed. A four-level engineering division model is constructed to realize the automatic association between unit engineering planning and control points, and to complete the closed-loop operation of online form filling, electronic signature approval and automatic archiving. Import the 3D model of the project and perform geometric subdivision according to the project hierarchy. Integrate the subdivided model units with the corresponding engineering units, control points and evaluation forms. Based on WebGL technology, realize the visualization rendering and interactive query of the project quality status.

[0006] Furthermore, the custom template parsing engine supports the import and parsing of Excel and Word format templates, converting the imported template files into a standardized XML format for storage.

[0007] Furthermore, the project type hierarchy model is a three-level hierarchy model of "unit project - sub-project - unit project", with the levels linked by the parent ID and each project type assigned a unique code.

[0008] Furthermore, the four-level project division model is a "section-unit project-sub-project-unit project" model, which dynamically generates a project division list tree through a recursive query algorithm.

[0009] Furthermore, the electronic signature uses the RSA asymmetric encryption algorithm to encrypt and store the signature information, and combines a timestamp mechanism to process the signature data.

[0010] Furthermore, the automatic archiving uses a PDF merging algorithm to sort and merge forms and attachments according to preset rules, automatically names them, and then synchronizes them to the pre-file module.

[0011] Furthermore, the batch configuration algorithm for control points employs batch database operations and Redis caching optimization, resulting in a response time of ≤5 seconds for batch configuration of thousands of control points.

[0012] Furthermore, the engineering 3D model supports importing BIM, OBJ, and FBX formats, which are then converted to GLB format after import.

[0013] Furthermore, the 3D model rendering employs Level of Detail (LOD) technology and piecewise loading technology, dynamically loading models of different precision based on the viewing distance.

[0014] Secondly, a pumped-storage power station quality inspection and management system, applied to the pumped-storage power station quality inspection and management method described in any of the preceding claims, specifically includes: The layered architecture module includes a data layer, a business logic layer, and a presentation layer. Each layer communicates with each other through standardized interfaces. The data layer uses MySQL to store structured data and Redis for caching optimization. The quality inspection and evaluation standard library module includes a custom template parsing engine and an engineering type hierarchical model, which realizes the batch association between control points and form templates through a batch configuration algorithm for control points; The quality inspection and management module constructs a four-level project division model to realize the automatic association between unit project planning and control points, and completes the closed-loop operation of online form filling, electronic signature approval and automatic archiving; The Quality 3D Model Module is used to import engineering 3D models and perform geometric subdivision according to engineering levels. It integrates the subdivided model units with the corresponding engineering units, control points, and inspection and evaluation forms, and realizes the visualization rendering and interactive query of engineering quality status based on WebGL technology. The underlying data linkage interface is used to realize real-time data synchronization between the quality assessment standard library module, the quality assessment management module, and the quality 3D model module.

[0015] The beneficial effects of this invention are as follows: (1) Significantly enhanced technological innovation: Breaking through the limitations of manual operation and independent modules in the existing system, the system enhances its technical difficulty and innovation through a custom template parsing engine, batch configuration algorithm for control points, and three-dimensional model subdivision and association technology.

[0019] The following description of exemplary embodiments is merely illustrative and is not intended to limit the invention or its application or use in any way. Techniques, methods, and apparatus known to those skilled in the art may not be discussed in detail herein, but where applicable, such techniques, methods, and apparatus should be considered part of this specification.

[0020] Example 1 See Figure 1 , Figure 1 This is a flowchart of a quality evaluation and management method for pumped storage power stations proposed in this invention. Specific steps may include: S1. Construct a layered modular architecture: Construct a layered modular architecture that includes a data layer, a business logic layer, and a presentation layer. Each layer communicates with each other through standardized interfaces. The data layer uses MySQL to store structured data and Redis to optimize caching. The data layer is designed with a multi-table data model, including a form template table, a project division table, a control point table, a quality inspection and evaluation data table, and a 3D model association table. Foreign key associations are used to ensure data consistency and integrity. A table partitioning strategy is adopted to separate historical inspection and evaluation data from real-time data. Redis is used to cache commonly used project types, template data, and inspection and evaluation status data, with a cache validity period of 1 hour. The business logic layer encapsulates form template parsing algorithms, project division level matching algorithms, control point batch configuration algorithms, 3D model subdivision algorithms, and approval process engines, and ensures the atomicity of form filling, approval, and archiving operations through a transaction management mechanism; The presentation layer adopts a component-based development model, encapsulating form filling components, 3D model rendering components, and data visualization components. It uses asynchronous loading technology to achieve smooth loading of large amounts of data and 3D models.

[0021] S2. Establish a quality inspection and evaluation standard library: Establish a quality inspection and evaluation standard library, realize standardized management of multi-format form templates through a custom template parsing engine, construct a hierarchical model of engineering types, and realize batch association between control points and form templates through a batch configuration algorithm for control points; The custom template parsing engine supports the import and parsing of Excel (.xlsx, .xls) and Word (.docx) format templates, defines a unified template format specification, including header format, field types, required field identifiers, signature area, attachment associated fields, and converts imported template files into standardized XML format for storage; The project type hierarchy model is a three-level hierarchy model of "unit project - sub-project - unit project". The levels are associated through the parent ID. Each project type is assigned a unique code, and the coding rule is "unit project code + sub-project code + unit project code". A hierarchy tree construction algorithm was developed to dynamically generate a project type list tree through a recursive query method, supporting operations such as adding, editing, deleting, moving up, and moving down. The batch configuration algorithm for control points adopts batch database operations and Redis caching optimization. It receives project type ID and basic control point information (number, name, importance identifier) ​​parameters, generates control point data through batch insertion, and automatically associates the corresponding form template. The response time for batch configuration of thousands of control points is ≤5 seconds. A "many-to-many" mapping mechanism is used to associate form templates with project types and control points, and the associated data is synchronized to the quality inspection and management module in real time.

[0022] S3. Implement full-process management of quality inspection and evaluation: Based on the quality inspection and evaluation standard library, implement full-process management of quality inspection and evaluation, construct a four-level engineering division model to realize the automatic association of unit engineering planning and control points, and complete the closed-loop operation of online form filling, electronic signature approval and automatic archiving. The fourth-level project division model is a "section-unit project-sub-project-unit project" model. It dynamically generates a project division list tree through a recursive query algorithm, supporting expand, collapse, and search functions, with a search response time ≤300ms. A unit project information data table is designed, automatically generating a serial number and system code when a new unit project is added. Electronic archive classification guidelines are embedded, establishing a relationship between directory codes, classification numbers, and unit projects, with specification selection via a drop-down selection component. Based on the unit project type, control points in the quality inspection and evaluation standard library are automatically matched, completing unit project planning and control point association. Online form filling is achieved through a custom form filling component. When loading the template, it automatically extracts unit project information to fill the table header. It supports data entry, temporary saving, and submission for approval. It also supports attachment upload and scanned document return. The electronic signature uses the RSA asymmetric encryption algorithm to encrypt and store the signature information, and combines the timestamp mechanism to process the signature data, generating a unique verification code that is bound to the form data; a workflow engine is used to build an automated approval process of "submission-review-approval-archiving", dynamically assigning approvers according to the personnel approval list planned for the project, updating the approval status in real time and sending approval reminder messages; Automatic archiving uses a PDF merging algorithm to sort and merge forms and attachments according to the preset rules of "Unit Project Quality Grade Evaluation Form > Unit Project Inspection and Acceptance Application Form > Selected Forms", automatically naming them with the full name of the Unit Project Quality Grade Evaluation Form, and synchronizing them to the pre-filing module.

Integrate the subdivided model units with the corresponding engineering units, control points and evaluation forms. Based on WebGL technology, realize the visualization rendering and interactive query of the engineering quality status. The engineering 3D model supports importing BIM, OBJ, and FBX formats. After import, it is converted to GLB format using a model format conversion algorithm to reduce file size and verify model integrity. The 3D model is geometrically segmented according to the four-level engineering division model. Each segmented model unit is assigned a unique identifier that is consistent with the engineering unit code. A model association algorithm is developed to integrate the model unit with the corresponding engineering unit, control point and verification form through the engineering unit code. The association relationship is stored in the model association table. The 3D model rendering employs Level of Detail (LOD) technology and piecewise loading technology. It dynamically loads models of different precision based on the viewing distance: low-precision models with ≤1000 faces are loaded at long distances, while high-precision models with ≥10000 faces are loaded at close distances. Based on WebGL technology, the quality status is mapped to the corresponding color for real-time rendering. It supports model rotation, scaling, and translation operations. Clicking on a model unit allows users to query the corresponding unit project, control points, and evaluation form information.

[0024] The quality inspection and evaluation standard library, quality inspection and evaluation management, and 3D model module achieve real-time data synchronization through the underlying data linkage interface. When the template, project type, and control point data in the quality inspection and evaluation standard library change, it is automatically synchronized to the quality inspection and evaluation management module. When the inspection and evaluation result data in the quality inspection and evaluation management module changes, it is automatically synchronized to the 3D model module to update the quality status rendering of the model.

Quality inspection and assessment planning completes the following steps in sequence: editing the project division, adding forms, and configuring form control points. Quality inspection and assessment control completes the following steps in sequence: online form filling, embedding electronic signatures, and online form approval.

It integrates the subdivided model units with the corresponding engineering units, control points and inspection forms, and realizes the visualization rendering and interactive query of the engineering quality status based on WebGL technology. Specifically, it is divided into two sub-processes: 3D model management and 3D model display. The 3D model management completes the model creation, model subdivision, logic construction, control point setting, and control point association in sequence. The 3D model display completes the display of the qualified and excellent status of the project quality, the viewing, rotation and scaling of the 3D model, and the viewing of the quality inspection form in sequence.
