Description

Technical Field

[0001] This invention relates to the field of ship design and manufacturing technology, and in particular to a collaborative method and system for ship construction data based on unified material coding. Background Technology

[0002] In the shipbuilding industry, the overall design unit (“design institute”) is responsible for designing the three-dimensional model of the ship and generating relevant design data and technical requirements. This data is used to guide the manufacturing unit (“assembly plant”) in material procurement, production preparation, and production process arrangement.

[0003] However, due to differences in material coding systems between the general design institute and the final assembly plant, the material codes in the general design institute's system cannot be directly matched with the final assembly plant's purchase orders and production preparation systems. This leads to the following problems:

[0004] 1. Inconsistent material information: The material codes provided by the general supplier are different from the local material coding system of the final assembly plant, which can easily lead to ordering errors.

[0005] 2. Disconnect between technical requirements and ordering information: The final assembly plant cannot directly obtain relevant technical requirements and design parameters from the overall 3D model, resulting in a cumbersome and error-prone production preparation process.

[0006] 3. Data silo problem: There is a lack of efficient collaboration mechanism between the overall institute and the final assembly plant, making it difficult to achieve real-time data exchange and updates.

[0007] Existing technologies attempt to resolve inconsistencies in material coding through manual mapping or simple lookup tables, but these methods are inefficient and prone to errors. Furthermore, existing collaborative design systems fail to effectively link technical requirements with ordering information, leading to rework and delays during production. Therefore, there is an urgent need for a collaborative design system based on a unified material coding mapping mechanism to achieve efficient data exchange and collaboration between the overall design institute and the final assembly plant. Summary of the Invention

[0008] In view of the shortcomings of the prior art described above, this invention proposes a shipbuilding data collaboration system and its implementation method based on a unified material coding mapping mechanism, aiming to solve the problems in the prior art. Through this invention, the material information in the overall design system can be seamlessly integrated with the final assembly plant's purchase orders and production preparation system, thereby improving the efficiency of design and manufacturing.

[0009] To achieve the above and other related objectives, this invention provides a method for collaborative shipbuilding data based on unified material coding, comprising the following steps:

[0010] S1. The overall system creates a material library, which includes a data table recording material information, including material descriptions and material codes. Next, a 3D component library is created, including creating 3D models of parts, defining parts and their model IDs, and referencing the material library to write material information onto the part's model attributes. Then, a complete 3D product model is built using the material parts from the component library, and the technical requirements of each part are clearly marked in the product 3D model. Finally, based on the product 3D model, the overall system outputs the ordering information required by the final assembly plant, forming an ordering data table. The ordering information includes the part's model ID, material information, technical requirement name, technical requirement number, and part quantity.

[0011] S2. The overall design institute transmits the material database data table to the final assembly plant. The final assembly plant formulates mapping rules based on the overall design institute's material database data table. Based on the mapping rules, the final assembly plant transforms the overall design institute's material description into its own material description. It then generates the final assembly plant's material code based on the material description, thereby obtaining the overall design institute-final assembly plant material information mapping relationship table and storing it in the database. The overall design institute-final assembly plant material information mapping relationship table records the mapping relationship table of the overall design institute model ID, overall design institute material information, technical requirement name, technical requirement number, and final assembly plant material information.

[0012] Optionally, it also includes step S3, whereby the final assembly plant places an order, specifically including:

[0013] S31. The final assembly plant receives the overall order data sheet;

[0014] S32. Material Information Conversion: The assembly plant uses the overall material information mapping relationship table to convert the material information in the assembly plant ordering data table into the material information of the assembly plant.

[0015] S33, Order List (POR) from the final assembly plant.

[0016] Optionally, the rules for the Purchase Order (POR) include:

[0017] A single order list procures multiple items;

[0018] Parts with the same technical requirements are purchased from a single order list;

[0019] In the order list, one item code corresponds to one line of data;

[0020] The order list records the model IDs of the parts designed by the overall system, and the information system retains the correspondence between the final assembly plant's order list and the overall system's model IDs.

[0021] Optionally, it also includes step S4: the final assembly plant receives the overall design model and revises the ordering data according to actual manufacturing needs, specifically including:

[0022] S41. The final assembly plant receives the overall design model; the final assembly plant receives the overall design model and imports it into the final assembly plant's production design environment. The import process does not change any information in the overall design model. During the import process, according to the overall design model and the final assembly plant's material information mapping relationship table, the final assembly plant's material description and final assembly plant's material code are obtained based on the model ID and written into the model.

[0023] S42. The final assembly plant revises the order data, extracts the model data of the received models, and obtains a model data record table. The model data record table records the model ID, the number of models received by the final assembly plant, the number of POR (Proof of Order) received by the final assembly plant, and whether the technical requirements have been received. Different handling measures are taken for the following situations:

[0024] Technical requirements not yet delivered to the factory: Overall technical requirements issued;

[0025] Technical requirements have been received at the factory, but there is no corresponding Proof of Order (POR) for the materials: POR issued by the final assembly plant;

[0026] If the quantity of materials received in the model is less than or equal to the POR quantity, no action is taken.

[0027] The quantity of materials received in the model is greater than the quantity of POR, so the quantity of POR is increased in the upgraded version.

[0028] Optionally, the material description includes the material name, standard number, specifications, and material; the material code is a unique material ID generated by a code generator based on the material description.

[0029] Optionally, the model ID encoding includes a professional code, type code, standard number, material code, and specification.

[0030] The present invention also provides a ship construction data collaboration system, which is used to implement the aforementioned ship construction data collaboration method.

[0031] Optionally, the material coding mapping module is used to map the material descriptions in the overall design system to the local material descriptions of the final assembly plant, and transform the material descriptions of the overall design system into the material descriptions of the final assembly plant based on the mapping rules; the collaborative design platform module is used to realize data exchange and collaboration between the overall design system and the final assembly plant.

[0032] As described above, this invention provides a data collaboration method and system for shipbuilding based on unified material codes. This data collaboration method first involves the overall design institute creating a 3D model and delivering the necessary ordering information to the final assembly plant, forming an ordering data table. Then, by establishing standardized mapping rules, the material descriptions from the overall design institute are transformed into those from the final assembly plant, resulting in a universally applicable mapping table of material information between the two institutions. Based on this, the final assembly plant receives the ordering data table from the overall design institute and issues an order list accordingly. Finally, the final assembly plant receives the design model from the overall design institute and collaboratively revises and confirms the ordering data based on actual manufacturing needs. This data collaboration method effectively solves the collaboration problem caused by inconsistent material codes between the overall design unit and the manufacturing unit, achieving seamless integration of material information at the design end with procurement orders and production preparation systems at the manufacturing end. This improves efficiency and accuracy in the design and manufacturing process, reduces rework and delays, and has significant industrial application value. Attached Figure Description

Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0035] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0036] like Figure 1 As shown, this invention provides a collaborative method for shipbuilding data based on unified material coding, comprising the following steps:

[0037] S1. The overall design department creates a 3D model to provide the data required for ordering by the final assembly plant. First, the overall design department constructs a 3D component library and defines material information conforming to the department's material coding rules within it. Then, it uses the components from the library to build a complete 3D product model, clearly annotating the technical requirements of each part. Finally, based on the 3D product model, the overall design department outputs the ordering information required by the final assembly plant. This ordering information includes key data such as model ID, material information (including material description and material code), technical requirement name, technical requirement number, and part quantity. Specifically, this includes:

[0038] S11. The overall 3D component library includes:

[0039] a. Create a material warehouse: The material warehouse includes a data table that records material information. The material information includes two main pieces of information: one is the material description, and the other is the material code.

[0040] Material description is used to describe the inherent attributes of materials (parts). Different categories of materials have different attribute items. Material description includes material name, standard number, specifications, and material. Material code is a unique material ID generated by a code generator based on the material description, as shown in the example in Table 1 below.

[0041] Table 1. Material Description and Material Code

[0042] Material Description Material Code Product Name: Marine Flanged Cast Steel Gate Check Valve; Standard Number: GB / T 585-2008; Specification: AS10300; Material: Cast Steel 241101000001

[0043] b. Create a 3D component library: First, create a 3D model of the part, then define a unique model ID for the part, such as: PVGBT585-G1-AS10300; then reference the information from the material library and write the material information corresponding to the 3D component into the model attributes of the part.

[0044] For example:

[0045] Model ID: PVGBT585-G1-AS10300;

[0046] Material Description: Material Name: Marine Flanged Cast Steel Gate Check Valve; Standard Number: GB / T 585-2008; Specification: AS10300; Material: Cast Steel

[0047] Material code: 241101000001

[0048] S12. Create a 3D model of the product by referencing the 3D component library, including:

[0049] a. Reference the part model from the 3D component library, call the part model from the 3D component library, and place it in the designed position on the ship; the model ID, material description, and material code information should be kept in reference and cannot be changed by the designer.

[0050] b. Define the technical requirements information of the parts on the product model, including the technical requirement name (such as the non-destructive testing standard for welds, the requirement for surface zinc plating thickness) and the technical requirement number.

[0051] Specifically, the model ID encoding includes a professional code, type code, standard number, material code, and specification, as shown in Table 2 below.

[0052] Table 2 Encoding Rules for Model IDs

[0053] Professional Code Type Code Standard number - Material code - Specification

[0054] illustrate:

[0055] (1) Professional code: 1 digit in length, such as P representing the pipe system professional.

[0056] (2) Type code: 1 digit in length, representing the type of component, see the type code reference table in Table 3. For example, V represents a valve.

[0057] Table 3 Type Code Comparison Table

[0058] Serial Number Type Code illustrate 1 P Pipes 2 F flange 3 C connector 4 R Different Paths 5 T Three-way 6 E elbow 7 V valve 8 G gasket 9 M Miscellaneous 10 I meter

[0059] (3) Standard number: Length is variable. It shall be determined in accordance with the standard number of CB / GB.

[0060] (4) Material code: 2 digits long, see the material code reference table in Table 4.

[0061] Table 4 Material Code Comparison Table

[0062] Reference Code Materials (to be filled in) Material (Des to be filled in) B1 FRP Fiberglass C1 TP2 TP2 D1 Bronze bronze D2 Copper copper G1 Cast Steel cast steel G2 Foged Steel Forged steel L1 Alufer aluminum alloy N2 BFe10-1-1 BFe10-1-1 N3 BFe10-1.6-1 BFe10-1.6-1 P4 Nylon nylon Q1 Q235A Q235A

[0063] (5) Specifications: Variable length. A set of specifications for each type of part, for example:

[0064] Flange: AS16125, where AS is the flange type, 16 is the kilogram class, and 125 is the nominal diameter;

[0065] Elbow: 1.5D_22X2.5_90, where 1.5D is the bending die, 22X2.5 is the outer diameter × wall thickness, and 90 is the angle of the elbow.

[0066] Examples of model ID encoding are shown in Table 5 below.

[0067] Table 5 Model ID Coding and Corresponding Description

[0068] Component type Model ID The description section (Des) should include (name, standard, specifications, material). flange PFGBT4450-Q1-AS16125 Blind flange (refer to pipe fittings for name), GB / T 4450, AS16125, Q235A elbow PEGBT12459-S4-1.5D-22X2.5-90 R1.5D butt-welded seamless elbow (refer to pipe fittings for name), GB / T 12459, 1.5D-22X2.5-45, SUS316L

[0069] In the overall product model, each part has multiple ordering information, including: model ID, material description, material code, technical requirement name, technical requirement number, and part quantity.

[0070] S13. Based on the product's 3D model, the overall system outputs the ordering information required by the final assembly plant, forming an ordering data table.

[0071] The order data is shown in Table 6 below:

[0072] Table 6 Order Data

[0073] Serial Number system Material Name Material Description Material Code Technical Requirements Name Technical Requirements Number quantity - - - - - - - -

[0074] Next, step S2, mapping the overall material information to the final assembly plant, is performed, including:

[0075] S21. Overall Material Warehouse Data Sheet Transferred to the Final Assembly Plant

[0076] S22. The final assembly plant formulates mapping rules based on the overall material inventory data table. The mapping rules are used to transform the material descriptions of the overall plant into the material descriptions of the final assembly plant. This standardized conversion can ensure that both parties achieve accurate correspondence in material identification.

[0077] As an example, the mapping rules are divided into two levels:

[0078] The first is the hierarchy of material description features, as shown in Table 7 below.

[0079] Table 7. Material Description Characteristics

[0080]

[0081] Second, the string hierarchy of material descriptions, including material name comparison (as shown in Table 8) and material information comparison (as shown in Table 9).

[0082] Table 8. Material Name Comparison

[0083]

[0084] Table 9 Material Information Comparison Table

[0085]

[0086] S23. Material Information Mapping: The final assembly plant uses a mapping module to transform the material description of the overall plant into the material description of the final assembly plant based on the mapping rules, and generates the material code of the final assembly plant based on the material description.

[0087] S24. Obtain the overall assembly plant material information mapping relationship table and save it in the database. The overall assembly plant material information mapping relationship table is a mapping relationship table that records the overall model ID, overall material information, technical requirement name, technical requirement number, and assembly plant material information, as shown in Table 10 below. The material information includes material description and material code.

[0088] Table 10: Overall Assembly Plant Material Information Mapping Relationship Table

[0089]

[0090] Next, proceed to step S3, where the final assembly plant places the order, including:

[0091] S31. Assembly Plant Receives Overall Order Data Sheet

[0092] S32. Material Information Conversion: The assembly plant uses the overall material information mapping relationship table to convert the material information in the assembly plant order data table into the material information of the assembly plant.

[0093] S33. The final assembly plant places an order (POR), as shown in Table 11 below.

[0094] A single order list procures multiple items;

[0095] One technical requirement corresponds to one purchase order (parts with the same technical requirement are purchased in one purchase order).

[0096] In the order list, one material code corresponds to one line of data.

[0097] The order list records the model IDs of the parts designed by the overall system, and the information system retains the correspondence between the final assembly plant's order list and the overall system's model IDs.

[0098] Table 11 Order List

[0099]

[0100] Next, in step S4, the assembly plant receives the overall design model and revises the ordering data according to actual manufacturing needs, including:

[0101] S41, Model of the Overall Assembly Plant Receiving Unit

[0102] The final assembly plant receives the overall design model and imports it into its production design environment. The import process does not change any information in the overall design model. Information such as the overall design model ID, overall design material description, and overall design material code remain unchanged.

[0103] During the import process, based on the "Overall Assembly Plant Material Information Mapping Relationship Table", the assembly plant material description and assembly plant material code are obtained according to the model ID and written into the model.

[0104] S42. The final assembly plant revises the order data, extracts the model data of the received models, and obtains the model data record table, as shown in Table 12 below. The model data record table records the model ID, the number of models received by the final assembly plant, the number of PORs of the final assembly plant, and whether the technical requirements have been delivered to the plant.

[0105] Table 12 Model Data Record Table

[0106]

[0107] Different measures will be taken for the following situations:

[0108] 1. Technical requirements not yet delivered to the factory: Overall technical requirements issued;

[0109] 2. Technical requirements have been received at the factory, but there is no corresponding Proof of Order (POR) for the materials: POR issued by the final assembly plant;

[0110] 3. If the quantity of materials received in the model is less than or equal to the quantity of POR, no action is taken.

[0111] 4. The quantity of materials received in the model is greater than the quantity of POR, so the quantity of POR is increased by upgrading.

[0112] This invention also provides a shipbuilding data collaboration system for implementing the aforementioned shipbuilding data collaboration method, specifically including a material coding mapping module and a collaborative design platform module.

[0113] The material coding mapping module is used to map the material descriptions in the overall design system to the local material descriptions of the final assembly plant. Based on the mapping rules, it transforms the material descriptions of the overall design system into the material descriptions of the final assembly plant, and generates the material codes of the final assembly plant based on the material descriptions. The collaborative design platform module is used to realize data exchange and collaboration between the overall design system and the final assembly plant.

[0114] In summary, this invention provides a data collaboration method and system for shipbuilding based on unified material codes. This data collaboration method first involves the overall design institute creating a 3D model and delivering the necessary ordering information to the final assembly plant, forming an ordering data table. Then, by establishing standardized mapping rules, the material descriptions from the overall design institute are transformed into those from the final assembly plant, resulting in a universally applicable mapping table of material information between the two institutions. Based on this, the final assembly plant receives the ordering data table from the overall design institute and issues an order list accordingly. Finally, the final assembly plant receives the design model from the overall design institute and collaboratively revises and confirms the ordering data based on actual manufacturing needs. This data collaboration method effectively solves the collaboration problem caused by inconsistent material codes between the overall design unit and the manufacturing unit, achieving seamless integration of material information at the design end with procurement orders and production preparation systems at the manufacturing end. This improves efficiency and accuracy in the design and manufacturing process, reduces rework and delays, and has significant industrial application value.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
