Description

Technical Field

[0001] This invention relates to the field of digital flowchart review technology, and in particular to a method and apparatus for reviewing and managing digital flowcharts. Background Technology

[0002] With the promotion of digitalization, more and more nuclear power plants are beginning digital transformation. Flowcharts are a common tool in nuclear power plant operation and production, and their digitization is a crucial part of this process. As flowcharts become digitized, their review process is also shifting towards digital review. Currently, in the review process of digital flowcharts, reviewers directly annotate and modify the original drawings, which can easily damage design benchmarks, lead to confusion in drawing versions, and present the pain point of difficulty in tracing and managing multiple rounds of review comments. Furthermore, in traditional review methods, review markings are mixed with drawing content, affecting the neatness of the drawings and the convenience of subsequent modifications, significantly reducing the efficiency and quality of the review process. Summary of the Invention

[0003] In view of this, it is necessary to provide a digital flowchart review and management method and device to effectively solve the technical problem of mixed content between review and drawing, which affects the authority of drawings and the ease of modification.

[0004] This invention provides a method for reviewing and managing digital flowcharts, comprising the following steps: Step S1: Define a drawing review mode that is independent of the drawing mode, and adapt the corresponding function set to the drawing mode and the drawing review mode; Step S2: Establish a separate data storage model for the base layer and the overlay layer. The base layer is used to store the drawing data generated in the drawing mode, and the overlay layer is used to store the review elements generated in the review mode. Establish a mapping relationship between each review element and the corresponding graphic element or the corresponding drawing area. Step S3: Review the flowchart drawn in the drawing mode based on the drawing review mode.

[0005] Preferably, step S1 specifically includes: The drawing mode's function set includes drawing editing, modification, adding elements, and deleting elements. The drawing operations directly affect the drawing data of the base layer. The review mode's function set includes adding review marks. The review operations directly affect the review elements of the overlay layer and are not used to modify the drawing data of the base layer.

[0006] Preferably, step S1 further includes defining a viewing mode, which is used to browse drawings and review marks, and the operation of the viewing mode does not affect the drawing data and review elements.

[0007] Preferably, step S2 specifically comprises: Modifications to the drawing data in the drawing mode take effect after approval; the overlay layer is independent of the base layer, and the review elements of the overlay layer are stored in a structured format.

[0008] Preferably, step S3 specifically comprises: In the drawing review mode, the reviewer edits the review elements of the flowchart, marks the status of the review elements as pending, and feeds back the corresponding review elements to the drafter; the drafter makes modifications in the drawing mode according to the corresponding review elements and updates the status of the corresponding review elements to processed; after the reviewer reviews, the status of the review elements is updated to closed.

[0009] Preferably, step S3 further includes: Record the editing history of each drawing element and update the editing history and corresponding drawing elements to the overlay layer simultaneously; record the drawing history of each round of drawing review and summarize different drawing history to export the drawing review report.

[0010] Preferably, step S3 further includes: The review elements of the overlay are classified, and the review elements are displayed in layers based on different categories. The classification of the review elements of the overlay includes classification by reviewer, problem type, processing status, element data type, and review round.

[0011] Preferably, step S3 further includes: Before switching from drawing review mode to drawing mode, check if there are any drawing elements in an unprocessed state. If so, prompt the user for confirmation. After switching from the drawing review mode to the drawing mode, the system detects the drawing element modification operations performed by the drawing user in the drawing mode, finds the associated drawing review elements according to the mapping relationship, and automatically modifies the associated drawing review elements accordingly.

[0012] Preferably, step S3 further includes: In the drawing review mode, the flowchart is reviewed in multiple rounds, and each round of review generates an independent overlay version. In the drawing review mode, multiple people can review the flowchart simultaneously. Different people review the drawing and generate independent overlay versions. A locking mechanism is used to avoid conflicts between multiple people reviewing the drawing. Different overlay versions are selected for version comparison, and the different overlay versions are displayed overlaid, with the differences marked.

[0013] The present invention also provides a digital flowchart review and management device, including a memory and a processor. The memory stores a computer program, and when the computer program is executed by the processor, it implements the digital flowchart review and management method.

[0014] Compared with existing technologies, the present invention has the following advantages: It separates and stores the review elements from the drawing data, ensuring that the original drawing data is not mistakenly altered, meeting the management requirements of nuclear safety-grade engineering, and guaranteeing the authority of the drawings and the convenience of subsequent modifications. Simultaneously, associating drawing elements with review elements makes the description of problems during review more intuitive and accurate, reducing communication misunderstandings and improving review efficiency and quality. Attached Figure Description

[0015] The accompanying drawings, which are included to provide a further understanding of the invention and form part of this application, illustrate exemplary embodiments of the invention and, together with their description, serve to explain the invention and do not constitute an undue limitation thereof. In the drawings: Figure 1 This is a flowchart of an embodiment of a digital flowchart review and management method provided by the present invention. Detailed Implementation

[0016] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0017] Example 1

[0018] Please see Figure 1 The digital flowchart review and management method in this embodiment specifically includes the following steps: Step S1: Define a drawing review mode that is independent of the drawing mode, and adapt the corresponding function set to the drawing mode and the drawing review mode; Step S2: Establish a separate data storage model for the base layer and the overlay layer. The base layer is used to store the drawing data generated in the drawing mode, and the overlay layer is used to store the review elements generated in the review mode. Establish a mapping relationship between each review element and the corresponding graphic element or the corresponding drawing area. Step S3: Review the flowchart drawn in the drawing mode based on the drawing review mode.

[0019] The digital flowchart review management method provided in this embodiment achieves separate storage and flexible control of review elements and original drawing data by defining independent review modes, ensuring the authority of design benchmarks, and improving review efficiency and quality.

[0020] Each step will be described in detail below.

[0021] Step S1: Mode Definition and Switching Mechanism This embodiment defines three operation modes: drawing mode, review mode, and viewing mode, which users can freely switch between via interface buttons or shortcut keys. In drawing mode, users can edit, modify, and add / delete elements on the drawing; the results directly affect the original drawing data. In review mode, users can add review markers, such as circles, annotations, highlights, and cloud lines, but cannot modify the original elements. All review elements are stored independently. In viewing mode, users can only browse the drawing and review markers; no modifications are possible, making it suitable for displaying and reading results. When switching modes, the interface toolbar, right-click menu, and shortcut keys dynamically adapt to the current mode's function set to avoid accidental operations.

[0022] Step S2: Construct an independent storage architecture for drawing review elements Establish a "baseline-overlay" data storage model. The baseline layer stores original drawing data, including elements, attributes, and topological relationships. This layer's data cannot be directly modified to ensure design authority. The overlay layer is independent of the baseline layer and stores all review elements, including annotation text, circled shapes, highlighted areas, and issue labels. Each review element is associated with a specific element or area in the baseline layer using an ID. Overlay layer data is stored in a structured format, such as JSON, containing the following information: element type (e.g., text / rectangle / circle / cloud / arrow); coordinate position and style (e.g., color, line width, transparency); associated element ID (optional); creator; creation time; review round; status (pending / confirmed / closed); and content (e.g., annotation text).

[0023] Step S3: Element drawing and management in drawing review mode, and the flow and closed-loop management of review comments. Once in drawing review mode, the system provides a dedicated toolbar containing annotation tools, issue markers, and highlighting tools. Annotation tools include text boxes, cloud lines, rectangles, circles, arrows, and freehand brushes; all elements drawn with these tools are displayed in a prominent color by default, such as red. Issue markers include predefined issue types, such as legend errors, connection errors, and missing codes; clicking on these generates an issue label with an icon. The highlighting tool allows you to highlight selected elements or areas to emphasize key areas of concern.

[0024] This embodiment also supports the workflow of review comments. After the reviewer raises a question, the system automatically notifies the drafter, such as via internal message or email. The drafter switches to drawing mode to view the question, modifies the drawing, and marks the corresponding review element as "processed". If the reviewer approves the drawing, they mark the review element as "closed"; if they do not approve it, they can reopen it and add comments.

[0025] All elements in the drawing review support secondary editing, such as moving, resizing, and modifying content. The editing history of each element is fully synchronized and updated to the overlay layer.

[0026] Record the complete review history, including the time the issue was raised, the time of modification, the time of review, and the content of each comment, forming a traceable audit trail. Record the review history of each round of review process, summarize all issues and their processing status, and export review reports for project managers to track progress.

[0027] Step S3 also includes control over the display of review elements. It provides functions for displaying and hiding review elements, including global display / hide, display / hide by type, display / hide by round, display / hide by personnel, and display / hide by element type. Global display / hide: Show / hide all review elements with one click, facilitating viewing the true effect of the drawing in drawing mode. Display / hide by type: Allows individual control over the display of text annotations, graphic marks, highlights, etc. Display / hide by round: For multi-round reviews, you can choose to display only the review elements from the current round. Display / hide by personnel: You can choose to display only the comments of a specific reviewer. Display / hide by review element type: Allows for layered display, such as filtering by reviewer, by issue type, or by processing status, facilitating focus on the respective responsibilities of multiple reviewers. When review elements are hidden, the drawing reverts to its original state, allowing the drafter to focus on revisions.

[0028] Step S3 also includes ensuring data consistency during mode switching. Before switching from review mode to drawing mode, the system automatically checks for any unprocessed review comments and prompts the user for confirmation. If a graphic element is modified in drawing mode, such as moving its position or deleting equipment, the associated review element will automatically adjust its position or be marked as "pending confirmation," prompting the reviewer to check whether the comments related to that graphic element need to be updated.

[0029] Step S3 also includes multi-round review and version comparison. It supports multi-round review, with each round generating an independent overlay version, allowing for easy review of historical review records. It supports concurrent review control by multiple users; when multiple users review or modify drawings simultaneously, the system uses version numbers and locking mechanisms to avoid conflicts and ensure data consistency. It provides a version comparison function, overlaying the current drawing with historical versions and highlighting the differences between the two versions for easy tracking of modifications.

[0030] Compared with existing technologies, this embodiment has the following technical advantages: It ensures the authority of design benchmarks by storing review marks and original drawing data separately, ensuring that original design data is not mistakenly altered and meeting the management requirements of nuclear safety-grade engineering; it standardizes the review process by implementing closed-loop management from problem identification and handling to verification, ensuring that each problem has a clear responsible person and a clear resolution; it facilitates efficient multi-user collaboration by supporting the filtering of review elements by personnel and type, allowing multiple users to work in parallel without interference, significantly improving team review efficiency; it provides historical traceability with complete review records and version comparison functions, providing reliable data for quality audits and experience feedback; it offers flexible view control with one-click showing / hiding of review elements, allowing for clear viewing of annotations during review and a clean working interface during drawing; and it reduces communication costs with precise element association and annotation tools, making problem descriptions more intuitive and accurate, reducing misunderstandings in verbal communication.

[0031] The following uses the review process of RCV system drawings for a nuclear power plant as an example to illustrate the specific implementation of this embodiment in different scenarios.

[0032] Scenario 1: First round of drawing review The drafter completes the initial draft of the RCV system diagram and submits it to the review process. The system automatically sets the drawing status to "Pending Review." The reviewer logs into the system, enters the "Pending Review Drawings" list, selects the RCV system diagram, and clicks "Enter Review." The system defaults to review mode, and the toolbar automatically switches to the review tools. The reviewer begins the review: An error is found in the valve legend; a gate valve is used instead of a regulating valve. The reviewer clicks the "Problem Marker" tool, selects the "Legend Error" type, adds a red problem label next to the valve, and enters the text "Should use a regulating valve." An incomplete pipeline connection is found; the area is circled using the cloud line tool, and the annotation "Pipeline not connected" is added. A missing equipment code is found; the equipment is highlighted using the highlight tool, and the annotation "Missing equipment code" is added. After the review is completed, the reviewer clicks "Submit Comments." The system saves all reviewed elements to an overlay layer and automatically notifies the drafter.

[0033] Scenario 2: Drawing Modification The drafter receives a notification and opens the RCV system diagram. At this point, they can select "Show Review Elements" to view all comments. Switching to drawing mode, the system prompts, "There are currently 3 unprocessed review comments. Continue switching?" After the drafter confirms, they enter drawing mode; the review elements are automatically hidden, but can also be manually opened for reference. The drafter modifies each comment accordingly: replacing the shut-off valve with a regulating valve; completing any missing pipeline connections; adding equipment codes for missing devices; after modification, switching back to review mode, and marking the three comments as "processed."

[0034] Scenario 3: Review and Closed Loop The reviewer reopens the drawing, and the system automatically locates the elements marked "Processed." The reviewer verifies each element: the valve has been correctly replaced, and the issue label status is changed to "Closed"; the pipeline has been connected, and the cloud line annotation is changed to "Closed"; the equipment code has been added, and the highlighted area is changed to "Closed." After all issues are closed, the reviewer clicks "Review Passed," and the drawing status is updated to "Approved," allowing the process to proceed to the next step.

[0035] Scenario 4: Multi-round drawing review and traceability Three months later, the project manager needs to trace the review history of the RCV system diagrams. Open the "Version Management" interface of the drawings and select the historical review version. The system displays all review elements from the first round of review, allowing the viewer of each comment, including the person who submitted it, the submission date, the person who modified it, the modification date, the reviewer, and the review date. The manager confirms that all issues have been closed and that the quality audit requirements are met.
