Description

Technical Field

[0001] The present application belongs to the technical field of digital experiment systems, and specifically relates to a design and simulation collaborative workbench system applied to a comprehensive application system of digital experiments in nuclear power engineering. Background Art

[0002] The nuclear power engineering experiment system (also known as the nuclear power engineering digital experiment integrated application system) is a complex system that integrates multiple elements, including experimental personnel, experimental subjects, experimental equipment, experimental simulations, experimental operating procedures, and experimental operating parameters. Its complexity has always been a major factor hindering the development and innovation of nuclear power engineering experimental technology. Nuclear power engineering experiments are highly technical and highly interdependent among various elements in the system. They involve the coordination and coupling of multiple departments, tasks, disciplines, and tools. They also face harsh operating conditions such as high temperature and high pressure, requiring full consideration of the reliability and safety of experimental operations. Therefore, to establish an efficient business execution environment for nuclear power engineering experiments, it is necessary to integrate the tasks, tools, knowledge, and data related to nuclear power engineering experiments within a unified framework. This will enable coordination and coupling across stages, departments, tools, and systems, and establish a unified and efficient digital business execution environment applicable to the entire life cycle of nuclear power engineering experiments.

[0003] "Research on the Application of System Engineering Methodology in Nuclear Reactor Digital Experiments" explains the top-level architecture of the digital experiment platform, including the business process architecture composed of the V model and business scenario diagram. Although it mentions the platform functional layered architecture composed of the business management system at the business layer, the experimental design and simulation collaborative workbench system at the application layer, the experimental knowledge system at the knowledge layer, and the basic functional system at the resource layer, it only studies the basic theory of digital experiments from the perspective of system engineering, and does not elaborate on the specific structure of the comprehensive application system of nuclear power engineering digital experiments.

[0004] In addition, the current tool integration and application platform only focuses on the interface encapsulation and calling of tool software, lacks the calling of tool software under the navigation of work task structure tree (WBS structure tree), and lacks the automatic accompaniment of various types of knowledge in the execution process of tool software. As a result, it is necessary to switch back and forth between the tool integration and application platform, business management system and knowledge management system, which affects the work efficiency of experimental execution. Various types of data generated during the execution process of tool software are also difficult to push to the corresponding task activities in real time, thereby providing a basis for monitoring the execution status of experimental tasks and recovering execution data of specific historical versions.

The task navigation module, associated with the project template construction and execution module and the knowledge companion module, is configured to receive and manage the user's projects and different activity models. It displays the task attributes corresponding to the user's selected target activity model on the task navigation interface based on user selection instructions. It also drives the project template construction and execution module and the knowledge companion module to refresh project templates and various types of accompanying knowledge based on user selection instructions. The project template construction and execution module is configured to automatically load the project template bound to the target activity model based on user selection instructions and display it on the project template construction and execution interface.

The knowledge companion module is configured to manage knowledge items associated with different activity models and knowledge items pushed through knowledge retrieval. It also automatically refreshes knowledge items associated with the target activity model and knowledge items pushed through knowledge retrieval based on user selection instructions and displays them on the accompanying knowledge interface.

[0032] Specifically, refer to Figure 2 The task list is displayed in the task navigation interface. Users can select a project and view the task properties corresponding to the activity model they are responsible for. Users can switch different activity models through the task navigation module. After switching the activity model through the task navigation module, it will drive the collaborative workbench system engineering template construction and execution module, and the knowledge accompanying module to refresh the engineering template, process data and various accompanying knowledge.

[0033] It should be noted that the work breakdown structure model can also be called a work task model or a WBS model. The target activity model is any one of the different activity models.

[0034] According to the technical solution provided in the embodiment of the present application, by setting up a task navigation module, an engineering template building and execution module, and a knowledge accompaniment module based on the work breakdown structure model in the design simulation collaborative workbench system, the problem of associated collaboration between tool integration application and task navigation and knowledge accompaniment in the existing technology is solved, and an experimental design simulation environment with features such as task navigation and synchronization, and automatic knowledge accompaniment is provided, which can effectively improve the efficiency and quality of experimental design analysis, and support real-time monitoring of the execution status of experimental tasks and recovery of execution data of specific historical versions.

[0035] In at least one embodiment of the present application, knowledge items include associated knowledge (including associated document templates), full documents, pictures, tables, itemized documents, and tool-related. The knowledge accompanying module includes an associated knowledge submodule, a full document submodule, a picture submodule, a table submodule, an itemized document submodule, and a tool-related submodule.

The table submodule is configured to manage tables and display it on the table page. The itemized document submodule is configured to manage itemized documents and display it on the itemized document page. The tool-related submodule is configured to manage tool-related and display it on the tool-related page.

[0036] Specifically, refer to Figure 2 and 10 After the user clicks on associated knowledge in the accompanying knowledge interface, the user enters the associated knowledge page; after the user clicks on full document in the accompanying knowledge interface, the user enters the full document page; after the user clicks on picture in the accompanying knowledge interface, the user enters the picture page; after the user clicks on table in the accompanying knowledge interface, the user enters the table page; after the user clicks on itemized document in the accompanying knowledge interface, the user enters the itemized document page; after the user clicks on tool-related in the accompanying knowledge interface, the user can enter the tool-related page.

[0037] It should be noted that in the accompanying knowledge interface, the "vocabulary" used in the search can be highlighted in the search results. In the knowledge accompanying module, users can view the knowledge items associated with any activity model and the knowledge items pushed through knowledge retrieval to guide the design and analysis work related to the activity model. The knowledge items pushed in the knowledge accompanying module include associated knowledge, full documents, pictures, tables, itemized documents, and tool-related. 1) Associated knowledge, showing strongly associated knowledge, including the input files of the activity, bound knowledge, and generated process data and outputs; 2) Full documents, itemized documents, pictures, and tables, showing the relevant knowledge retrieved based on attributes such as activity name and activity keywords; 3) Tool-related, showing knowledge retrieved based on the file format of the tool component.

[0038] On the tool-related page, first search and filter the tool-related data and knowledge based on the tool's data format (such as *.dwg), then sort the data and knowledge based on the properties of the active model and display them in pages. There is no filtering in the sorting.

[0039] In at least one embodiment of the present application, the associated knowledge is displayed in a list format, and the information displayed on the associated knowledge page includes serial number, name, type, confidentiality level, contributor, keywords, summary, source and attachments.

[0040] Specifically, after the user clicks "Related Knowledge" on the accompanying knowledge interface, he or she can enter the related knowledge page, which can specifically display information such as serial number, name, type, confidentiality level, contributor, keywords, summary, source and attachments.

[0041] In at least one embodiment of the present application, sources are divided into five categories: input and output of the project; input, output, and process data of the project / stage; input, output, and process data of the project / stage / activity; local upload; when knowledge is disassembled from a document, the disassembled parent document is displayed.

[0042] In at least one embodiment of the present application, the design simulation collaborative workbench system applied to the nuclear power engineering digital experiment comprehensive application system also includes a tool component library and an engineering template library module associated with the task navigation module. The task navigation module is further configured to drive the tool component library and the engineering template library module to refresh the engineering template according to the user's selection instruction. The tool component library and the engineering template library module are configured to call the tool components of the tool component library and the engineering template library module according to the user's call instruction when the active model is not bound to the engineering template or a new engineering template is created, configure the control flow and data flow, form the engineering template required for the execution of the target active model, and upload the engineering template required for the execution of the target active model to the experimental knowledge application submodule.

[0043] For example, refer to Figure 6 In the project template building and execution module, the project template bound to the active model can be automatically loaded for the execution of the active model, and the loaded project template can be edited again, or other project templates in the tool component library and project template library module can be called to replace the loaded project template. When the active model is not bound to a project template or a new project template is created, the user can call the tool components of the tool component library and project template library module through drag-and-drop modeling, configure the control flow and data flow, form the project template required for the execution of the active model, and upload the built project template to the knowledge application sub-module.

[0044] refer to Figure 6 In the project template building and execution module, there are control flow table pages and data flow table pages. When you drag a tool component to the modeling interface, the position and icon displayed on the control flow table page and the data flow table page are the same. On the control flow table page, red lines are used to identify the logical relationship between tool components. On the data flow table page, blue lines are used to indicate the input and output parameter mapping relationship between tool components. You can click the blue line to pop up the parameter mapping configuration page. You can establish the mapping between component parameters by dragging and dropping, which is expressed by green lines.

[0045] In at least one embodiment of the present application, reference Figure 3,The tool component library and project template library modules include the tool ,component library, project template library and the most recently used templates.

[0046] It should be noted that users can directly call tool component models from the tool component library by dragging and dropping. Users can view tool components and project templates on the local client and call them by dragging and dropping. They can also browse more to view tool components or project templates in the knowledge application submodule and download them locally. The project template list interface in the project template library uses a list display method, including template name, confidentiality level, contributors, keywords, summary, local existence, download progress, and operations.

[0047] refer to Figure 5 The engineering template library supports the management of engineering templates in various specific scenarios. Engineering templates call several tool components through the drag-and-drop modeling method and define and configure control flows and data flows to form engineering templates for specific business scenarios. The engineering templates express the composition of the tool components required in a specific business scenario, as well as the execution order and data transfer relationship of each tool component.

[0048] In at least one embodiment of the present application, reference Figure 3 and Figure 4 The tool component library supports component management of commercial software, component management of nuclear reactor professional analysis software, component management of self-developed software, and component management of UG-based three-dimensional piping layout software, word-based document preparation auxiliary tools, etc. Commercial software includes but is not limited to CFX, fluent, matlab, UG, autoCAD, etc. Nuclear reactor professional analysis software includes but is not limited to relap5, flica, cobra, apros, etc. Self-developed software includes but is not limited to experimental data structuring tools, pressure vessel design tools, heat exchanger design tools, and the Modelica-based Nuclear Reactor Unified Modeling and Analysis Platform (NUMAP).

[0049] Figure 4 The data flow logic of the design and simulation collaborative workbench system for the nuclear power engineering digital experiment integrated application system is shown. Users can model collaborative work in the process interface. User parameters and instructions are issued through the platform's unified data management framework. The data is then passed to the tool integration middleware for data parsing, primarily into text and control scripts. The parsed text data, such as parameters, variables, inputs and outputs, and control script data for software startup, shutdown, program opening, and closing, are passed through the software interface to self-developed or commercial software, enabling collaborative simulation.

[0050] In at least one embodiment of the present application, the design and simulation collaborative workbench system for a nuclear power engineering digital experiment integrated application system further includes a process data and status management module. This module is configured to manage the input and output data of each tool component during the execution of engineering templates corresponding to different activity models, and to directly locate the folder containing the execution-related data of the local client tool components based on user search commands. The task navigation module is further configured to drive the process data and status management module to refresh process data based on user selection commands.

[0051] The embodiments of the present application can provide an experimental design simulation environment with features such as task navigation and synchronization, template building and execution, automatic knowledge accompaniment and process data, which can further effectively improve the efficiency and quality of experimental design analysis, support real-time monitoring of the execution status of experimental tasks and recovery of execution data of specific historical versions.

[0052] refer to Figure 6 In the Process Data and Status Management module, users can view the input and output data of each tool component during the execution of the project template corresponding to the active model and manually configure input files for a specific tool component. The Process Data and Status Management module allows users to directly locate the folders containing data related to the execution of the local client tool component, including input data folders, output data folders, and other data folders. Data from the Process Data and Status Management module can be uploaded to the Task Structure View in the Experimental Data Lifecycle Management module.

[0053] refer to Figure 6 In the project template building and execution module, the execution environment includes operation buttons such as create, open, save, execute, stop, parameter association, upload process data, and upload project template. It supports drag-and-drop assembly of project templates and saving, as well as opening existing project templates. The data flow transmission relationship between components can be configured through the parameter association page. The project template can be saved locally by the user, and saved as knowledge in the experimental knowledge application sub-module, making it convenient for other users to share and use the project template. After clicking execute, the project template executes the relevant components in the order of the control flow; during the execution process, the input and output data of the components are automatically transmitted according to the transmission relationship defined by the data flow; after the execution is completed, the process data is automatically uploaded, and manual upload by the user is also supported.

[0054] Refer to Figure 7 and Figure 8 When executing design simulation tasks through the local client, it supports uploading the task process data to the platform data warehouse of the nuclear power engineering digital experiment comprehensive application system for unified management. At the same time, it supports accessing the process data through the platform data warehouse and downloading it for use. After downloading, it can be directly restored to the local design simulation environment when the process data was generated, so that users can continue the design simulation tasks in this environment.

[0055] In at least one embodiment of the present application, referring to FIG7 , process data mainly includes a parameter list of all components involved in a specific simulation process, wherein the parameters are divided into two categories: value parameters and file parameters. All value parameters are centrally stored in the project file, while the file parameters are stored as independent attachment files. The project file and the parameter file including the file parameters are associated with each other and uploaded to the platform server in the form of a file. In this way, by uploading files between the local client and the platform server, a certain process data in the simulation process can be stored in the form of a file to the platform server, and the process data can be downloaded from the platform server in the form of a file to the local client when needed. Then, the local client rebuilds the simulation process and restores the parameter list of the component based on the information in the file, thus completing the recovery of the local specific design simulation environment.

[0056] For example, refer to Figure 7a After associating the project file with the parameter file containing the file parameters, the files are uploaded to the platform server as files. Specifically, the project file and the file parameters are associated and packaged. The local client of the Nuclear Power Engineering Digital Experiment Integrated Application System sends a file upload request to the platform server via the Hypertext Transfer Protocol (HTTP). If the local client receives a feedback request from the platform server via HTTP, the packaged file is uploaded to the platform server. If the local client does not receive a feedback request from the platform server via HTTP, the process ends.

[0057] In at least one embodiment of the present application, reference Figure 9 For tool component file parameters, the platform server stores historical file versions. The local client provides an interactive interface for selecting historical file versions. This allows the local client to restore historical file parameter versions. Based on the file version selected by the user, the project file is downloaded from the platform server and the file parameters are refreshed.

[0058] It should be noted that Figure 8 、 Figure 9 and Figure 10 "XXX" or "XX" represent replaceable text content.

[0059] refer to Figure 7b The user clicks on the file history version selection interactive interface of the local client to obtain the historical version data file and selects the file version. The local client downloads the project file and parameter file corresponding to the file history version from the platform server. After the user opens the project file, the corresponding associated parameter file path is obtained.

[0060] The above-mentioned embodiments of the present application provide an execution environment for experimental engineers to carry out specific R&D work, including accepting and executing tasks assigned by superiors, calling tools to build and execute automated design simulation processes, accumulating and reusing knowledge, querying resource libraries, publishing / sharing task data, etc. When designing a simulation collaborative workbench system, a client-based task processing environment is provided for engineers, which conforms to the engineers' usage habits. In the collaborative workbench system, users can view the tool components and project templates of the local client and call them in a drag-and-drop manner, thereby realizing the design simulation of active models for nuclear power engineering experiments, and supporting the management of process data and status, making it convenient to view the file parameters of each historical version.

[0061] It should be noted that the combination of the various technical features in the embodiments of the present application is not limited to the combination described in the embodiments of the present application or the combination described in the specific embodiments. All technical features described in the present application can be freely combined or combined in any way unless there is a contradiction between them.

[0062] As used in this application and the claims, unless the context clearly indicates otherwise, the words "a," "an," and / or "the" are not intended to refer to the singular but may include the plural. Generally speaking, the term "comprising" only indicates the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.
