Description

[0002] According to the basic architecture of the digital integrated R&D platform for the new generation of large surface ships, there is a lack of unified management of the three-dimensional models and business processes of the three major disciplines of hull, engine, and electrical. The scope of ship product models is relatively wide, involving not only ship design, but also parts catalogs to support design, planning, manufacturing and testing information to implement design, engineering models for analyzing design (schemes), and logistics models for supporting and maintaining the ship itself. The ship product model is not a monolithic model. It spans the above-mentioned life cycle stages and exists in many different (although interconnected) systems, applications, and data warehouses.

[0051] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] Reference Figure 1 , shows a flow chart of the steps of a method for constructing a ship model library of the present application, which can be applied to electronic equipment, wherein the method can specifically include the following steps:

[0053] S101. Create a model domain name of a ship component through a pre-set product data modeling platform;

[0054] S102, according to the model domain name of the ship component, determining a plurality of class diagrams corresponding to the model domain name, the class diagrams being used to represent the model information;

[0055] S103. Generate a product metamodel corresponding to the ship component according to the model domain name, class diagram and semantic model of the ship component, wherein the product metamodel at least includes various domains, classes and association relationships between domains and classes, and wherein the semantic model is determined according to feature information of different components.

[0056] Among them, the product semantic model, i.e. the semantic model of the ship component, contains the model name, identifier, attribute fields and behavior methods, as well as the relationship between the product model and other class models. The product data modeling platform can graphically express the data characteristics of the product according to the product semantics and generate metamodel information. The metamodel information covers the attributes and relationships of the product and can be generated based on graphical tools. The information is stored in a specified tree structure for easy index integration. The standard data management platform can obtain product model information based on object-oriented data services, parse class diagrams, and generate attribute tables and model relationships.

[0057] In order to realize data definition and representation, it is necessary to describe the entities, entity features, entity classification and association relationships of the data semantic model, and at the same time provide a semantic-based common data standard framework to realize the integrated editing and management of product data models.

[0058] Since data semantic models are relatively abstract and different data models lack a unified standard system, the following problems exist in product data integration and management: how to standardize the modeling and description of the semantics of product data; how to automatically integrate and manage product data models; and how to achieve data synchronization and mapping between data models and common standard documents.

[0059] The embodiment of the present application provides a method for implementing a general data standard framework based on semantics, which extracts characteristic behavior information based on the characteristics of the product itself to describe the product semantic model, and constructs a defined data meta-model, system class and relationship structure in a specific domain on the product data modeling platform based on the product semantic model. The model domain is read using a general data standard management platform, and the data model is remapped and a standard document is generated according to the standard structure of model classification, model class diagram and model attributes, so as to realize data modeling of product data semantics and realize integrated editing and management of product data models.

[0060] Another embodiment of the present application further supplements the method for constructing the ship model library provided in the above embodiment.

[0061] Optionally, a product metamodel corresponding to the ship component is generated according to the model domain name, the class diagram and the semantic model of the ship component, including:

[0062] A product metamodel corresponding to the ship components is generated in a graphical way according to the domain name, class diagram and product semantics of the ship components.

[0063] Optionally, create model domain names for ship components through a pre-set product data modeling platform, including:

[0064] Through the pre-set data modeling platform, build the model domain of common parts, structures, equipment, and water pipelines;

[0065] Based on the model domain of common parts, structures, equipment, and water pipelines, create ship identification, hull configuration, and engineering changes under the model domain.

[0066] Optionally, a product metamodel corresponding to the ship component is generated according to the model domain name, the class diagram and the semantic model of the ship component, including:

[0067] According to the semantic model of the ship component, a new class diagram is created under the domain to create a product class diagram. The product class diagram at least includes the hull object, design components and attribute information, wherein the attribute information at least includes the attribute type, definition sequence number, number and description field information;

[0068] Establish the relationship between class diagrams;

[0069] According to the domain name, class diagram and the relationship between class diagrams, a product metamodel corresponding to the ship components is generated.

[0070] Optionally, the semantic model of the ship component includes at least a model name, an identifier, attribute fields and behavior methods, and an association relationship between the product model and other class models.

[0071] Optionally, the method further comprises:

[0072] The universal standard management platform is bound to the model domain, and a data document corresponding to the product metamodel is generated according to the product metamodel corresponding to the ship component. The data document is used to represent the semantic information of the model under the model domain and modify the model information online.

[0073] The framework implements the integrated editing and management of product modeling and standard data expression based on product data, realizes the mapping relationship between the two platforms, and synchronizes model changes and modifications.

[0074] like Figure 2 As shown in the figure, based on product semantics, the product model can be constructed in a graphical way through the product data modeling platform. The specific steps are as follows:

[0075] Step 1: Log in to the product data modeling platform;

[0076] Step 2: Create a new domain and set the domain name. Multiple classes can be stored under this domain to describe the model information.

[0077] Step 3: Create a class diagram based on product semantics, and use a graphical approach to establish models, attributes, and relationships;

[0078] Step 4: After the class diagram is established, save and parse it to generate the product metamodel;

[0079] Step 5: In this domain, you can operate and maintain the created classes, attributes, relationships, etc.

[0080] Step 6: Log in to the standard management platform;

[0081] Step 7: The universal standard management platform binds the specified model domain and generates an online standard data document based on the defined model structure. The document describes the semantic information of all models under the domain and the model information can be modified online.

[0082] Step 8. The document can number the model classes, and the document generates a specified chapter based on the number, and a description can be added for the chapter;

[0083] Step 9: Use the standard management platform to generate a traceability matrix for online documents and integrate the attributes and relationships of the model;

[0084] Step 10: Generate a word document based on the standard management platform and export the existing model standards.

[0085] The embodiments of the present application provide a standard product model architecture and data format, standardize the semantic expression of the product, realize the mapping relationship and integration of data models and data standards, and facilitate the unified management and maintenance of data models.

[0086] Exemplarily, firstly, based on the model-driven architecture, a product data modeling platform is independently constructed through the prototype chain mechanism of JavaScript, providing an object-oriented graphical modeling and parsing environment.

[0087] The SCIM (Common Information Model) domain covers all data and information of the entire life cycle of a ship, including design, analysis, manufacturing, testing, commissioning, management, maintenance, and scrapping. Based on the standard data format of SCIM, information transfer and reuse in an integrated data environment can be achieved. The following uses SCIM as a basic use case to briefly describe the implementation method of the common data standard framework.

[0088] In the product data modeling platform, according to the semantic model of ship general information, Figure 3 The workflow is used to build model domains such as product data management, general parts, structure, equipment, and water pipelines. New domains can be created under each domain. Taking product data management (PDM) as an example, new domains such as ship identification, hull configuration, and engineering changes can be created under this domain to further subdivide.

[0089] Create a new class diagram under the domain, create a product class diagram, add classes such as hull objects and design components, and click the "Property Bar" above to define field information such as serial number, number, description, etc. according to the property type.

[0090] Click the class model, drag the arrow icon and specify another class model to define the inheritance and association relationship between classes.

[0091] After the class diagram is constructed, the product metadata model is generated by saving and parsing, and the domain, model, and attribute association information are managed through a tree structure. Figure 4 shown.

[0092] Log in to the standard management platform, take the product data management (pdm) under the SCIM level as an example, automatically parse all the hierarchical structures under the current domain by completing the binding with the PDM domain, and map and expand them according to the tree structure of the product data modeling platform. This mapping relationship constructs the navigation tree node objects in sequence through the persistent data structures such as the relationship and category of the metadata model, and ensures that each tree node corresponds to a class model. Based on the class model, a standard document data element is generated, including the class diagram, attributes and description information of the model.

[0093] Generate standard data documents under the PDM domain through system mapping relationships, such as Figure 5 The document contains the class diagram, class name, class attributes and corresponding description under each domain.

[0094] Right-click on the node of the standard tree and add a number to sort the nodes and adjust the standard data document. Click the corresponding tree node and the document will automatically locate to the specified location. When the class diagram and class information are modified in the document, the model information in the product data modeling platform will also be synchronized. The corresponding relationship between the model structure and the document directory is as follows: Figure 6 shown.

[0095] By generating a tracking matrix, the model's entities, attributes, and associations can be integrated into a table for unified management and reference.

[0096] Finally, the Word export service can be used to parse all class diagrams in the document into images, generate tables of attributes and related information, and export them into Word offline documents. The chapter directory of the document is consistent with the online standard data document.

[0097] Based on the above steps, the node information management and content detailed information management of the ship general information model are realized. The model information can be edited and displayed through the general standard framework, and the general information model document can be generated to facilitate the subsequent data integration and unified management and reference of data standards.

[0098] It should be noted that each implementable method in this embodiment may be implemented separately, or may be implemented in combination in any manner without conflict, and this application is not limited thereto.
