Abstract
Description
Technical Field
[0001] This application relates to the field of shipbuilding technology, and more specifically, to a method, system, and ship design method for managing ship design modification opinions. Background Technology
[0002] Currently, digital design technology is being used more and more widely in ship design. The ship structural design process mainly includes the detailed design stage and the production design stage. Domestic shipyards generally use 2D drafting software such as AutoCAD in the detailed design stage, while 3D modeling software is generally used in the production design stage. From the detailed design stage to the production design stage, there is a process of converting 2D drawings into 3D models.
[0003] Currently, because the detailed design phase and the production design phase use different and unrelated software, when information changes occur in the detailed design phase, it is impossible to link the modified information with the production design phase so that the 3D model can be modified synchronously with the 2D drawings, which affects the shipbuilding schedule and efficiency.
[0004] In summary, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Summary of the Invention
[0005] The purpose of this application is to provide a method, system and method for managing ship design modification opinions, which can automatically collect, register and effectively distribute modification information of detailed design two-dimensional drawings during the ship structural design process to production designers.
[0006] Firstly, a method for managing opinions on ship design modifications is provided, including the following steps:
[0007] S1. Obtain predetermined modification information of the ship structure, modify the ship structure according to each predetermined modification information, and mark the modification position of the ship structure with a modification mark; generate a graphical interactive file including multiple modification marks.
[0008] S2. Extract statistical information for each modification marker based on the graphical interactive file; and associate the statistical information with the ship structure and output it.
[0009] In one implementation, in step S1, the modification of the ship structure is a modification of the two-dimensional graphic; after step S2, the three-dimensional design graphic of the ship structure is modified accordingly based on the output of multiple statistical information.
[0010] In one embodiment, in step S1, marking the modification marks includes the following: using multiple closed shapes to circle the segments in the ship structure that have been modified, and locating and naming each of the closed shapes.
[0011] In one embodiment, the closed shape is a two-dimensional wireframe, which includes first coordinate information and second coordinate information, and the positioning of the closed shape is named as the third coordinate.
[0012] In one implementation, when multiple modifications are included within each closed shape, multiple modification markers are sequentially marked.
[0013] In one implementation, each of the modification markers is a cloud-shaped line, the circled position of the cloud-shaped line representing a modification position; each of the cloud-shaped lines is configured with a name and a line color.
[0014] In one embodiment, the line color includes a first color and a second color. When the line color is the first color, it indicates that the modification mark corresponding to the cloud-shaped line has been turned off. When the line color is the second color, it indicates that the modification mark corresponding to the cloud-shaped line has not been turned off.
[0015] In one embodiment, each cloud-shaped line is located in a different modification layer; the specific modification content represented by each cloud-shaped line is marked in the name, which is the layer name of the cloud-shaped line.
[0016] In one implementation, the statistical information includes:
[0017] Modify position information: Obtain the three-dimensional coordinate information of the three-dimensional design drawing that needs to be modified based on the closed shape and the positioning name.
[0018] Modified content information: Obtain the modified content based on the layer name of the cloud-like lines.
[0019] In one implementation, the closed graphic and the positioning name are located in different layers.
[0020] Secondly, a ship design modification opinion management system is also provided, including a memory and a processor. The memory stores a computer program, which, when executed by the processor, implements the ship design modification opinion management method provided in the first aspect.
[0021] Thirdly, a ship design method is also provided, in which the hull is divided into multiple sections, each section is assigned a number, and a three-dimensional model is created based on the two-dimensional design drawings of each section. When the two-dimensional design drawings are modified, the ship design modification opinion management method provided in the first aspect is used to obtain each modification mark, and the three-dimensional graphics of each section are modified one by one according to each modification mark.
[0022] Compared with the prior art, the beneficial effects of this application are as follows:
[0023] In the technical solution of this application, during the ship structural design process, after design modifications are made to the two-dimensional graphics, this application can statistically analyze and output specific modification information. The modification information for different sections is then summarized and sent to the corresponding production designers, and each section is modified one by one. This ensures that ship design can transmit detailed design drawing modification information in a timely, efficient, accurate, and systematic manner, and has high application and promotion value in the field of ship design. It avoids errors and omissions in modification information statistics and untimely information transmission, thereby improving shipbuilding efficiency. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0032] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0033] According to the first aspect of this application, see Figure 1 First, a method for managing ship design modification comments is provided, including the following steps:
[0034] S1. Obtain the planned modification information of the ship structure, modify the ship structure according to each planned modification information, and mark the modification location of the ship structure with modification marks; generate a graphical interactive file including multiple modification marks.
[0035] It should be noted that, based on the ship's structural form, the hull is divided into five regions along its length: bow, stern, cargo hold, engine room, and superstructure, with one set of drawings for each region. This embodiment uses one set of drawings as an example. Each set of drawings includes multiple longitudinal sections, transverse sections, and plan views for that region to illustrate the hull structure of that region.
[0036] S2. Extract statistical information for each modification mark from the graphical interactive file; associate the statistical information with the ship structure and output it.
[0037] In one implementation, the modification of the ship structure in step S1 is a modification of the two-dimensional graphic. After step S2, the three-dimensional design graphic of the ship structure is modified accordingly based on multiple output statistical information.
[0038] In one embodiment, in step S1, marking the modification marks includes the following: using multiple closed shapes 1 to circle the segments in the ship structure that have been modified, and positioning and naming each closed shape 1 2.
[0039] It should be noted that during the hull production design process, based on the actual construction and production needs, the hull will be divided into more sections on the basis of the hull area division. Each section has a corresponding number. In the process of converting two-dimensional drawings into three-dimensional models, the modeling is also carried out according to the hull section division.
[0040] In one implementation, such as Figure 2 As shown, closed shape 1 is a two-dimensional wireframe, including first and second coordinate information, and its positioning name 2 is the third coordinate. Therefore, when modifying a three-dimensional shape, the three-dimensional coordinate information of the modified position can be obtained through closed shape 1 and positioning name 2, and the modified position can be accurately located based on the three-dimensional coordinate information.
[0041] Specifically, multiple segment layers are created in the ship structure drawings, and each segment layer is named "Segment ***", for example: Segment 201. A closed curve is then used within each segment layer to define the area to be represented by that segment, such as... Figure 2 As shown. Closed figure 1 is a polyline, and there can be multiple polylines. The same cross-section and the same node can be defined by multiple segments.
[0042] Create a new positioning layer in the ship structure drawings. Using this positioning layer, mark the position of each defined area within each closed shape (1) using the multi-line text function. Use SimSun font and the text input format: Positioning: ****, for example, Positioning: FR45. Figure 2 As shown.
[0043] In one implementation, the closed graphic 1 and the positioning name 2 are placed in different layers for classification and extraction.
[0044] In one implementation, when multiple modifications are included within each closed shape 1, multiple modification markers are sequentially marked.
[0045] Specifically, to facilitate subsequent work, the ship's profiles, plates, markings, etc., will be divided into multiple layers as needed. When making modifications, the changes will be made in the corresponding layer according to the normal procedure.
[0046] In one implementation, each modification is marked as a cloud-shaped line, and the position of the cloud-shaped line represents a modification position; each cloud-shaped line is configured with a name and line color.
[0047] In one implementation, the line color includes a first color and a second color. When the line color is the first color, it indicates that the modification marker corresponding to the cloud-like line is turned off. When the line color is the second color, it indicates that the modification marker corresponding to the cloud-like line is not turned off.
[0048] In one implementation, each cloud-shaped line is placed within a different modification layer to avoid confusion when reading information. Therefore, each cloud-shaped line represents a modification and is placed within a single layer. If each layer contains multiple modification information, the probability of reading errors increases. The specific modification represented by each cloud-shaped line is labeled in its name, which is the layer name of the cloud-shaped line.
[0049] Specifically, a new modification layer must be created for each batch of modifications. In this layer, all modified content in the drawing should be circled with a cloud-shaped outline. The modification layer must be named as follows: Cloud Line-AA + Reason for Modification + Date. Here, AA represents the shipowner / ship inspection / production; the reason for modification should be as concise and accurate as possible for easy retrieval of modified content later; the date should be an 8-digit number, placed at the end of the name, in year-month-day order. For example: Cloud Line-Shipowner Requests Addition of Manhole Cover Design 20190909.
[0050] In the editing layer, the color of the cloud-shaped lines indicates the status of the edit. When the cloud-shaped line is white, the edit is considered closed; other colors indicate that the edit is not closed. If the edit is closed, the cloud-shaped line color can be set to white to manage the edit status.
[0051] It should be noted that after completing the annotation of all segments within a drawing, the segment layer, positioning layer, and modification layer should be hidden to facilitate other changes, such as when setting positioning points for imported drawings, making it easier to copy the entire layer content.
[0052] In one implementation, the statistical information includes:
[0053] Modify position information: Obtain the 3D coordinate information of the 3D design drawing that needs to be modified based on closed shape 1 and positioning name 2.
[0054] Edit information: Obtain the reason for modification, modification time, and comment category based on the layer name of the cloud-like lines.
[0055] In one implementation, the graphical interactive file in step S1 is a DXF format file, which is a common format that can be read by various drawing tools.
[0056] It should be noted that, as Figure 3 As shown, when extracting statistical information, at least the following should be included:
[0057] A. The filename of each interactive graphic file includes the ship number and the drawing name.
[0058] B. Obtain the modification location based on the content of the positioning layer: Based on the absolute coordinates of closed shape 1, obtain the defined range of the segment to be modified and its two-dimensional relative positional relationship with the ship structure. Obtain the three-dimensional position information based on positioning name 2.
[0059] C. Obtain the specific content of the modifications based on the modified layer: Within the predefined area, obtain the cloud-shaped lines marked for each modification. Extract the segment number based on the location of the cloud-shaped lines, i.e., the relative positional relationship between the cloud-shaped lines and closed shape 1. Extract the reason for modification, time, and comment category based on the name of the layer containing the cloud-shaped lines. Extract the comment status based on the color of the cloud-shaped lines.
[0060] It should be noted that after making a modification in one area within the 3D graphic, the color of the cloud-shaped line should be changed to white.
[0061] According to a second aspect of this application, a ship design modification opinion management system is also provided, including a memory and a processor. The memory stores a computer program, which, when executed by the processor, implements the ship design modification opinion management method provided in the first aspect, such as... Figure 4 As shown.
[0062] According to a third aspect of this application, a ship design method is also provided, in which the hull is divided into multiple sections, each section is assigned a number, and a three-dimensional model is created based on the two-dimensional design drawings of each section. After modifications are made to the two-dimensional design drawings, the ship design modification opinion management method provided in the first aspect is used to obtain each modification mark, and the three-dimensional graphics are modified one by one according to each modification mark.
[0063] In one implementation, when modifications to the segmented two-dimensional diagram are required, the numbers are statistically analyzed and fed back to the three-dimensional modeling unit.
[0064] In summary, during the ship structural design process, after modifications are made to the two-dimensional drawings, this application enables the collection and output of specific modification information. The modification information for different sections is then summarized and sent to the corresponding production designers, who then modify each section individually. This ensures that ship design can transmit detailed design drawing modification information in a timely, efficient, accurate, and systematic manner, possessing high application and promotion value in the ship design field. It avoids errors and omissions in modification information statistics and untimely information transmission, thereby improving shipbuilding efficiency.
[0065] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
