Description

Technical Field

[0001] This invention relates to the technical field of collaborative drawing review scheme design for a ship supervision project management system, specifically to a collaborative drawing review platform for a ship supervision project management system. Background Technology

[0002] In the construction of complex projects such as ships, the review of design drawings is a crucial step in ensuring that the final product meets design requirements and specifications. This process typically involves collaboration between the designer (such as the shipyard), the supervisor, and the owner. Traditional drawing review methods rely heavily on offline operations, resulting in cumbersome and inefficient processes. Typically, the designer needs to distribute a large number of paper drawings or electronic files to the supervisor and owner via physical media or email. Each party's reviewers then conduct independent reviews, recording any issues found in paper forms or separate electronic documents. Subsequently, multiple meetings, phone calls, or emails are needed to collect, summarize, discuss, and confirm these scattered opinions, ultimately forming a unified set of feedback to be provided to the designer for revisions.

[0003] This traditional model has several inherent flaws. First, the process is lengthy; the sequential workflow forces all parties to wait for the previous step to complete before starting the next, severely delaying project progress. Second, collaboration efficiency is extremely low; opinions are scattered across different personnel and documents in different formats, making the summarization process prone to omissions or errors, and resulting in high communication costs. Third, version management is chaotic; there is a lack of effective tracking methods for drawing modifications and updates to opinions, easily leading to inconsistencies in the versions of documents used by different parties, causing misunderstandings and rework. Fourth, the feedback and processing of opinions are opaque; the designer's responses are difficult to accurately correspond to the original opinions, and review records cannot be fully preserved, hindering process traceability and accountability. Although some document management or workflow management systems exist, they are not specifically designed for collaborative drawing review scenarios and cannot effectively support the core needs unique to drawing review, such as parallel annotation, structured summary of opinions, and multi-role workflow collaboration. Therefore, there is an urgent need in this field for a specialized online collaborative platform that can connect the entire drawing review process to solve the above pain points and improve the quality and efficiency of drawing review work.

[0004] Therefore, the existing technology still needs further development. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a collaborative drawing review platform for ship supervision project management system to solve the problems existing in the prior art.

[0006] To achieve the above technical objectives, the present invention provides a collaborative drawing review platform for a ship supervision project management system, comprising: It includes an account management module, a permission management module, a drawing catalog management module, and a drawing review process management module. The account management module is configured to manage account information of multiple users. The permission management module is configured to control system function access permissions based on user roles. The drawing catalog management module is configured to maintain the drawing catalog and process drawing file uploads. The drawing review process management module is configured to coordinate online collaborative drawing review activities and process the registration and summarization of drawing review opinions.

[0007] Specifically, the drawing review process management module also includes a parallel drawing review sub-module, which is configured to allow multiple reviewers to independently review the same drawing and register their review comments at the same time, and the reviewers can only view their own comments.

[0008] Specifically, the drawing review process management module further includes an opinion collection and review sub-module, which is configured to automatically collect the opinions of all parties after the drawing review is completed, organize online review, and merge the opinions of the supervisor and the owner after the review is passed before releasing them to the shipyard.

[0009] Specifically, the account management module is also configured to store user account information, including numeric account number, name, first letter of name, age, gender, affiliated unit, business role, email address, and contact number, and when the first letter of the name is repeated, letter identifiers are added in order of age.

[0010] Specifically, it also includes an information prompt module, which is configured to send review notifications to users through an external service interface and support users to temporarily access specified review tasks via links and keys.

[0011] Specifically, the opinion summary and review submodule is also configured to process shipyard responses, including allowing shipyards to respond online or upload responses in batches via Excel files. The system automatically parses and updates the opinion status and is configured to support the upload of upgraded drawing files.

[0012] Specifically, the account management module is also configured to provide a unique user identification rule, which generates an account identifier based on the first letter of the name and a sequence of age to ensure account uniqueness.

[0013] Specifically, the information prompt module further integrates the WeChat service account interface, and sends the image review invitation through WeChat service notification. After the user clicks the link and enters the key, they can obtain limited-time image review permissions.

[0014] Specifically, it also includes a version management module, which is configured to track the versions of drawing files and review comments, record process changes, and provide version control functions.

[0015] Specifically, it also includes a multilingual switching module, which is configured to support one-click switching of the system interface language and integrates a translation interface to translate review comments into the specified language.

[0016] Beneficial effects: The collaborative drawing review platform of the ship supervision project management system provided by this invention brings significant technological advancements and multiple beneficial effects compared to traditional drawing review methods. First, this invention achieves digitization and collaboration of the drawing review process through an integrated online platform, fundamentally improving work efficiency. The platform supports multiple reviewers to review the same drawing in parallel, breaking the constraints of the traditional serial mode and significantly shortening the overall cycle of the drawing review task. Online submission, automatic summarization, and structured storage of opinions avoid omissions and errors easily caused by manual collection and organization, ensuring the completeness and accuracy of information.

[0017] Secondly, this invention establishes a clear, standardized, and traceable workflow for drawing review. From drawing upload, task assignment, feedback submission, online review to feedback and revisions, the entire process is conducted systematically on the platform and leaves a complete record. This closed-loop management ensures that every comment is effectively addressed, greatly enhancing the transparency and reliability of the process. The integrated version management function retains historical versions for every change to drawings and comments, completely resolving version confusion issues and providing a solid data foundation for project auditing and quality retrospective analysis.

[0018] Third, this invention optimizes the user experience and lowers the barrier to entry through high automation and flexible integration capabilities.

[0020] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0021] First, it should be noted that the core purpose of the collaborative drawing review platform of the ship supervision project management system provided by this invention is to solve the problems of low collaboration efficiency, cumbersome processes, difficulty in tracking opinions, and chaotic version management among shipyards, owners, and supervisors in the drawing review stage during ship construction supervision. By constructing a centralized online platform that integrates functions such as account permission management, drawing catalog management, collaborative drawing review process control, information prompts, and version management, the platform achieves standardization, parallelization, and traceability of the drawing review work, significantly improving the quality and efficiency of drawing review.

[0022] The system platform is composed of multiple collaborative software functional modules, which can be deployed on cloud servers and accessed by users through client browsers or mobile terminals.

[0023] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0024] Please see Figure 1 This invention provides a collaborative drawing review platform for a ship supervision project management system, comprising: The system includes an account management module, a permission management module, a drawing catalog management module, and a drawing review process management module. The account management module is configured to manage account information for multiple users. The permission management module is configured to control system function access permissions based on user roles. The drawing catalog management module is configured to maintain the drawing catalog and process drawing file uploads. The drawing review process management module is configured to coordinate online collaborative drawing review activities and process the registration and summarization of drawing review comments.

[0025] It should be further explained that the collaborative drawing review platform of the ship supervision project management system includes an account management module, a permission management module, a drawing catalog management module, and a drawing review process management module. The account management module stores user account information for all participants in a database. Its data structure includes, but is not limited to, numeric account number, name, initials of name, age, gender, affiliated unit (e.g., shipyard, owner company, supervision company), business role (e.g., project manager, drawing review engineer, professional head), email address, and contact number. This module provides interfaces for user registration, information entry, query, and modification. The permission management module is linked to the account management module and internally defines a role-based access control (RBAC) policy. For example, the system administrator has the highest privileges; supervision personnel can create drawing review tasks and summarize opinions; owner personnel can participate in the review; and shipyard personnel mainly upload drawings and respond to opinions. Different user roles see distinct system menus and have different operable functions after logging in, thus ensuring the security of system data and the orderliness of the process. The drawing catalog management module provides a structured interface that allows users (usually shipyard or supervisor administrators) to create and maintain drawing catalog trees according to project, specialty, system, and other dimensions. This module supports uploading, online previewing, downloading, and deleting common drawing file formats (such as DWG, PDF, DOCX), and associates uploaded drawings with entries in the catalog. The drawing review process management module is the core of the entire platform, driving the entire drawing review process. This module is responsible for creating drawing review tasks, assigning specific drawings to designated reviewers (from the supervisor or owner), providing online annotation and feedback tools, and automatically collecting and storing all review feedback to form an initial feedback pool. The collaborative work of these four basic modules constitutes a minimum feasible but fully functional online drawing review system. Its beneficial effect lies in integrating scattered drawing review activities onto a unified digital platform for the first time, laying the foundation for collaborative work and fundamentally avoiding the chaotic situation of traditional offline methods where communication relied on email, feedback was based on forms, and versions were easily confused.

[0026] Specifically, the drawing review process management module also includes a parallel drawing review sub-module, which is configured to allow multiple reviewers to independently review the same drawing and register their review comments at the same time, and the reviewers can only view their own comments.

[0027] Specifically, the drawing review process management module further includes an opinion collection and review sub-module, which is configured to automatically collect the opinions of all parties after the drawing review is completed, organize online review, and merge the opinions of the supervisor and the owner after the review is passed before releasing them to the shipyard.

[0028] It should be further explained that, to further improve the efficiency of drawing review, the parallel drawing review submodule defined in this invention is integrated into the drawing review process management module. When a new drawing review task is created and multiple reviewers are assigned, this submodule generates an independent drawing review view for each reviewer. This means that multiple reviewers can simultaneously open the same drawing online, using integrated tools (such as circles, arrows, and text boxes) to annotate and fill in comments, while their operations and comments are invisible to each other during the drawing review process. This parallel processing mode greatly shortens the overall cycle of the drawing review task. Its beneficial effect is that it transforms the traditional serial drawing review (one person reviews before the next) into a highly efficient parallel mode, and avoids mutual interference among reviewers, ensuring the independence of comments. After the parallel drawing review stage is completed, the comment summary and review submodule defined in this invention begins to work. This submodule automatically runs a summary program to collect the comments raised by all reviewers on the same drawing and generate a preliminary summary report according to a preset format (such as comment description, submitter, submission time, and associated drawing location). Subsequently, this submodule initiates an online review process. For example, it creates a virtual review meeting room and invites professional representatives from both the supervisor and the owner to participate. Reviewers can jointly review the summary report, discuss it via voice, video, or text chat, and evaluate each comment (e.g., adopt, modify, or reject). Review conclusions are recorded in real time. Finally, the system automatically merges and generates a formal list of comments that have passed the review and represent the joint conclusions of the supervisor and the owner, and officially releases it to the shipowner through the platform. The beneficial effect of this process is that it achieves closed-loop management of comment processing, making the entire process from collection and discussion to decision-making online and visible, ensuring the authority and accuracy of the comments, and leaving a clear audit trail.

[0029] Specifically, the account management module is also configured to store user account information, including numeric account number, name, first letter of name, age, gender, affiliated unit, business role, email address, and contact number, and when the first letter of the name is repeated, letter identifiers are added in order of age.

[0030] Specifically, the account management module is also configured to provide a unique user identification rule, which generates an account identifier based on the first letter of the name and a sequence of age to ensure account uniqueness.

[0031] It should be further explained that, to ensure the uniqueness and manageability of account identifiers in a large-scale user environment, the account management module defined in this invention calls a specific algorithm to process the "first letter of name" field when storing user information. This algorithm first extracts the initial letter combination of the user's name in Pinyin (e.g., Zhang Sanfeng → ZSF). Then, it queries the database to check if other accounts with the same initial letter combination already exist. If not, it directly uses that combination as part of its unique user identifier. If it already exists, the algorithm sorts these users according to their age and appends lowercase letters after the initial letter of each user's name (e.g., the youngest Zhang Sanfeng is identified as ZSFa, the second youngest as ZSFb, and so on). As further defined in this invention, this rule ensures that even in a large project with a large number of users sharing the same initial letter, the system can automatically generate unique account identifiers without manual intervention from the administrator. Its beneficial effect is that it provides an automated, low-conflict user identifier generation mechanism, greatly reducing the maintenance burden on system administrators and ensuring the uniqueness and systematic nature of user data.

[0032] Specifically, it also includes an information prompt module, which is configured to send review notifications to users through an external service interface and support users to temporarily access specified review tasks via links and keys.

[0033] Specifically, the information prompt module further integrates the WeChat service account interface, and sends the image review invitation through WeChat service notification. After the user clicks the link and enters the key, they can obtain limited-time image review permissions.

[0034] It should be further explained that, to improve system activity and task response speed, the information prompt module defined in this invention is integrated into the platform. This module monitors key events within the system, such as new drawing review task assignments, feedback responses, and review meeting invitations. When an event is triggered, the module calls the application programming interface (API) of an external service, such as an SMS gateway or email server API, to send a notification message to the target user. The message content includes a hyperlink directly pointing to the relevant task page, and a one-time, time-limited key (or verification code). After clicking the link, the user is redirected to an authentication page. After entering the key, temporary access is granted, allowing direct access to the task interface for processing without going through a complex login and navigation process. As further optimized by this invention, this module specifically integrates the WeChat service account API. The system pushes the drawing review notification message template to the WeChat server, which then sends it to the user's WeChat client. The user receives the reminder in their daily WeChat account, and after clicking, opens the task page in their mobile browser and enters the key. The advantage of this WeChat-integrated approach is that it utilizes the most frequently used mobile application, greatly improving the delivery rate of notifications and the user's response speed, and ensuring that the drawing review task can be processed in a timely manner.

[0035] Specifically, the opinion summary and review submodule is also configured to process shipyard responses, including allowing shipyards to respond online or upload responses in batches via Excel files. The system automatically parses and updates the opinion status and is configured to support the upload of upgraded drawing files.

[0036] It should be further explained that, to facilitate efficient processing of large amounts of review comments by shipyard users, the functionality defined in this invention provides a flexible entry point for comment responses within the comment summary and review submodule. Shipyard users can view and respond to comments one by one on the platform's web interface, just like the reviewers, or they can download an Excel template file provided by the system. This template file is pre-filled with all the comment items that need to be responded to. Shipyard staff can use Excel software locally to batch fill in the response content, and then upload the file back through the platform's upload interface. The system backend has a dedicated file parsing engine that can automatically read the contents of the Excel file and accurately match the response content with the original comment items in the system according to a predefined format, updating the status (e.g., "responded" or "pending review"). Simultaneously, this entry point allows shipyards to upload new versions of drawing files modified for this version of the comments. Its beneficial effect is that it provides shipyard users with maximum operational flexibility, supporting both efficient online interaction and compatibility with traditional offline batch processing habits. In particular, it lowers the barrier to entry and improves response efficiency for users accustomed to using spreadsheet software.

[0037] Specifically, it also includes a version management module, which is configured to track the versions of drawing files and review comments, record process changes, and provide version control functions.

[0038] It should be further explained that, to ensure traceability throughout the entire project process, the version management module defined in this invention is integrated throughout the entire platform. This module automatically timestamps and labels each uploaded drawing file, each modification of review comments, and each generation of comment summary report with a version number (e.g., v1.0, v1.1, v2.0). All historical version files and data are persistently stored and a clear relationship is established (e.g., v1.1 version drawings correspond to v1.1 version review comment summary reports). Users can use the version history viewing interface provided by the system to go back to any historical version and view the file content and review status at that time. Its beneficial effect is that it completely solves the long-standing problem of version management in engineering projects, ensuring that all operations are traceable and providing a complete data foundation for process traceability, responsibility definition, and experience summarization.

[0039] Specifically, it also includes a multilingual switching module, which is configured to support one-click switching of the system interface language and integrates a translation interface to translate review comments into the specified language.

[0040] It should be further explained that, to meet the needs of international projects, the multilingual switching module defined in this invention operates at the user interface and content levels. This module first provides a one-click function to switch the interface language (e.g., Chinese / English), which is achieved by calling different language resource packages. More importantly, this module integrates the API interface of a third-party machine translation service (e.g., Google Translate, Microsoft Translate). When users need to understand foreign language comments, they can select a single or batch of review comments to trigger the translation function. The system will send the selected text content to the translation API and display the returned translation to the user in real time. Its beneficial effects include breaking down language barriers among project participants, promoting seamless collaboration among international teams, and improving the platform's universality and applicability.

[0041] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
