Description

Technical Field

[0001] The present invention relates to a method for ship parts change management and automatic transmission and updating in the shipbuilding industry, and belongs to the field of management technology in digital ship design and manufacturing technology. Background Art

[0002] With the development of the shipbuilding industry, we can rely on ship design software to complete the entire stage of preliminary design, detailed design and production design of ships, and realize the collaborative design of hull structure, piping, electrical and other disciplines through parametric modeling. Currently, the commonly used ship design software includes AutoCAD, CATIA, ShipConstructor and AVEVA Marine, among which AVEVA Marine is widely used in ship and ocean engineering design. AVEVA Marine has strong integration, realizing cross-disciplinary functional integration of hull, outfitting, engineering and design, and providing integrated solutions for ship companies. It provides powerful 3D modeling tools that enable designers to create detailed ship models, support multiple data formats and interfaces, and facilitate integration with other software systems. And with a modular design, users can select and configure different functional modules according to their needs to meet the needs of different projects.

[0003] During the ship design and construction process, ship models require numerous revisions. Consequently, detailed design corrections—updated drawings following design revisions—are frequently received. These revised drawings must be promptly distributed to the operations site during production. From model design to revisions, to working drawing modifications, nesting drawing modifications, work log entry, list data transfer, and finally, cutting instruction data revisions—the entire revision process involves multiple steps. If any of these steps are not tracked and closed promptly, the optimal opportunity for revisions will be missed, significantly increasing construction costs. Furthermore, production technology optimization involves model revisions, drawing modifications, nesting instruction modifications, log entry, and list transfer. However, part change operations lack integrated steps, and cross-process operations often lead to inefficient change transfer and tracking and closure management.

[0004] Therefore, there is an urgent need for a method for ship parts change management and automatic transmission and update, which can simultaneously have the characteristics of ship parts change management and automatic transmission and update after change to solve the problems raised in the above background technology.

[0006] In view of the problems and deficiencies in the prior art, the present invention aims to provide a method for ship parts change management and automatic transmission and update, which extracts ship parts data from AM software in real time, obtains initial part parameter data and current part parameter data after analysis, and

[0007] Parameter data is then compared to generate updated part parameter data. Part parameters are then parametrically edited based on the updated part parameter data, and updated drawings are generated based on the updated part parameter data. Finally, the updated nesting data is transmitted from the updated drawings. This allows for efficient change management of part parameters, drawings, and nesting, improving operational efficiency across all processes. This addresses the issues raised in the aforementioned background technology.

[0052] It should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure.

[0053] The examples are only for illustrative purposes and are not intended to limit the scope of protection of the present disclosure.

[0054] It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0055] Example

[0056] The present invention discloses a method for managing changes in ship parts and automatically transmitting updates. The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. Figures 1 to 3 As shown, the present invention mainly includes the following steps:

[0057] Step 1: Extract the part geometry data file from the AM software for the first time, parse it, and store the initial part parameter data in the processing database;

[0058] Step 2: Extract the part geometry data file from the AM software again, parse it, and store the current part parameter data in the processing database;

[0059] Step 3: Compare the initial part parameter data with the current part parameter data. If there is any data change, obtain the updated part parameter data and store it in the processing database.

[0060] Step 4: Generate updated drawings based on the updated parameter data of the parts in the processing database and store them back in the processing database;

[0061] Step 5: Read and save the updated drawings in the processing database to complete the transfer change of the nesting data and update the nesting part set.

[0062] AVEVA Marine's AM ship design software is an integrated ship design solution developed specifically for the contract and detailed design phases. It supports rapid 3D modeling and performance analysis of hull structures. Especially during the conceptual and contract design phases, it can quickly generate mathematical hull models and perform basic calculations such as weight, stability, and tank capacity. AVEVA Marine supports data transfer throughout the entire process, from conceptual design to production design, reducing the risk of design iterations. It also supports multi-site collaboration for large and complex projects, offers flexible configuration options to accommodate diverse design processes, and improves overall efficiency through digital tools.

[0063] In an embodiment of the present invention, a part geometry data file is extracted by AVEVA Marine (AM) ship design software. The part geometry data file extracted for the first time is parsed to obtain the part parameter data therein and stored in a post-processing database, which is represented as initial part parameter data. The part geometry data file extracted from the AM software is parsed using secondary development software. The extracted part geometry data file is represented as a GEN file, which is a standardized format for storing geometric information, mainly used to describe the structural data of basic graphic elements such as points, lines, and surfaces. The GEN file records the spatial coordinates, topological relationships, and attribute information of geometric objects in text or binary form, and is compatible with CAD drawing software and nesting systems. Then, the part geometry data GEN file currently extracted is extracted and parsed to extract the relevant fields of the part parameter data in the file. The changes in the part parameter data can be identified by comparing the initial part parameter data and the current part parameter data through hash values ​​or numerical values.

[0064] If it is identified that the part parameter data has been updated, the current part parameter data will be treated as the part updated parameter data and saved back to the post-processing database. The method of changing the part is mainly based on the modification of the part parameter data. By understanding the initial part parameter data and the data that needs to be changed (i.e., the part updated parameter data), the part data is changed. Based on the part parameter configuration editing tool, the geometric entity is changed by changing the parameters. The parameter changes include the length, groove, end shape, opening, etc. of the part. The part parameter configuration editing tool can be selected as SolidWorks or Pro / E configuration. Its function is to define and adjust the key parameters of the part, and improve the design efficiency and accuracy through automation and visualization functions. Specifically, it is necessary to obtain the changed value of the part parameter, determine the updated parameter node based on the parameter change value, and then recreate and reconstruct the model tree according to the parameter node. The change of part data also includes a detailed record of the part change, and a part parameter change record is generated and saved in the processing database for each change. This step can be achieved through the database generator.

[0065] Next, the updated part parameter data is drawn as a geometric entity through a visualization process, and the specific rules for parameter writing are converted into a two-dimensional drawing and displayed on the front end. The specific steps include:

[0066] Step 4.1, classify each element or element combination in the drawing of the initial part drawing and construct a drawing model;

[0067] Step 4.2, read the updated parameter data of the parts from the processing database and bring it into all drawing models;

[0068] Step 4.3, drawing the updated primitive or primitive combination through the geometric algorithm in the drawing model;

[0069] Step 4.4, generating an updated drawing from the updated graphic element or graphic element combination and saving it to the processing database.

[0070] Specifically, primitives are represented as lines, arcs, circles, ellipses, and text, while primitive combinations are represented as part ends, openings, lines, and annotations. Based on the actual meaning of each primitive or primitive combination on the original part drawing, the primitives on the 2D drawing are classified and the corresponding drawing model is constructed. First, a reference framework for the part is established based on datum primitives (such as axes and centerlines). Based on this framework, the exterior and interior shapes of the part are drawn using outline primitives. After the outline is drawn, dimensions are added to the drawing based on the dimension primitives. Technical specification primitives (such as surface finish and tolerance) are then integrated into the drawing model. Part update parameter data is then read from the processing database and incorporated into each drawing model. Geometric algorithms within the drawing model create primitives or primitive combinations with specific meanings on the drawing, thereby converting the 2D drawing. The geometric algorithms first identify the primitives in the 2D drawing and classify them based on characteristics such as shape, size, and position. During the geometric algorithm processing, the drawing model is updated based on the identified primitives and geometric transformation results, including adding new primitives, modifying the properties and positions of existing primitives, and deleting primitives that are no longer needed. These transformation operations can be implemented through matrix operations, which can ensure the accuracy and efficiency of the transformation. Combined with the embedded drawing unit (such as CAD drawing), the conversion of two-dimensional drawings can eventually be achieved. The drawings in the method of the present invention always use the latest part drawings as the display object, and changes to the drawings include drawing updates caused by part changes and drawing updates caused by editing the drawings themselves.

[0071] By following these steps, part parameters can be automatically regenerated after they are changed. Each time a change is made, the corresponding drawing file is saved. A drawing change record is generated after the drawing file is successfully saved. This can be achieved through database triggers. Each time a change is made, a drawing change record is generated and saved in the processing database. The drawing change record includes the storage path, file name, version number, and description of the change. The drawing change record in the processing database is generated and stored after the drawing file is successfully saved.

[0072] The management of drawings includes checking the drawing versions and checking the drawing change records. For checking the drawing versions: after the drawing is generated, it is saved in the processing database and corresponds to the corresponding version number, with the initial version being 000. After subsequent changes occur, the version number increases accordingly, and the latest version number is displayed by default. By selecting the required version number, the drawing with the corresponding version number can be displayed. Specifically, the drawings are classified by LOT number and drawing type (such as part details). The opened drawing can view all versions of the changed drawings. Drawing comparison is also provided to automatically mark the differences between different versions. Specifically, the drawings are automatically generated based on the parametric principle. After the parameters are changed, the system tracks the changed parameters and selects different versions for comparison. If you choose to compare versions 001 and 000, the part where the parameters of version 001 have changed will be highlighted and marked with an arrow in the front section of the drawing.

[0073] As for viewing the drawing change record: when the part parameters are modified, a change data record will be generated. All nodes where changes occur will require the filling of change records. The change records are classified by the change object (such as parts, part details, etc.), LOT number, and drawing type (such as part details), and the change type and description and other information are recorded together. At the same time, viewing the drawing change record can also close the change parameters. That is, when a part is modified and saved to the modification ledger, a modification ledger mark will be added. Select the mark to view the modification content, and the modification ledger will be displayed as unclosed. However, when the designer makes corresponding changes to subsequent operations such as nesting and cutting data, the ledger will be displayed as closed, and the modification ledger operation cannot continue.

[0074] The method of changing nesting and data is to add the nesting part data by batch to the nesting processing function module through nesting transfer, and save it as nesting processing database data and nesting diagram after nesting processing.

[0075] Step 5.1, save and read the updated drawing from the processing database;

[0076] Step 5.2: Process the updated drawing elements and layers, including selecting layers and separating blocks.

[0077] Step 5.3, transfer the nesting in the form of blocks and save it to the specified reading path as a nesting part set.

[0078] Based on reading the latest drawings from the processing database, the drawing elements and layers are processed through DXF file parsing technology to achieve layer selection (removing the annotation layer) and block separation (T-profiles are divided into two drawings). Establishing a segment index table can quickly locate core data segments, including global parameter segments, layer attribute segments, geometric element segments, and block segments. By traversing the layer attribute segment, the layer name corresponding to the group code is extracted for matching. The annotation-related entity type identifiers include DIMENSION (annotation entity), LEADER (leader), TEXT (annotation text), etc. Check the group code to obtain the name of the layer to which it belongs. If it matches the annotation layer, the entity is skipped, otherwise the annotation layer is removed. Then identify the block segment to extract the block definition information, use the block name as the key to store the entity list and the insertion base point coordinates in the block, and perform matrix transformation on the entity coordinates in the block according to the insertion point, scale, and angle. Recursively call the decomposition function, and the decomposed entity inherits the layer, color and other properties of the original block to ensure consistency with the original Figure 1 Then the drawing is saved as a block in the specified reading path as a nesting part set through nesting transfer.

[0079] When the part drawing is changed, the content of the nesting transfer is also changed. When saving the nesting transfer, the updated drawing is saved first. After saving the updated drawing, the nesting master, part parameters and nesting position are stored in the processing database, and the relationship between the nesting master and part parameters is stored in the processing database. Each time it is saved, a nesting update record is generated and saved through a database trigger. Figure 4 The figure shows the client interface diagram of the ship parts change management and automatic transmission update method.

[0080] In order to realize the above-mentioned embodiment, the present application also discloses a system for ship parts change management and automatic transmission and update. It includes an extraction and parsing module, which is used to extract part geometry data files from AM software multiple times, obtain initial part parameter data and current part parameter data after parsing, and store them in a processing database.

A nesting change module, which is used to read and save the updated drawings in the processing database to complete the transmission change of the updated nesting data and update the nesting part set.
