Obviously, the described embodiments are only some of the embodiments of the present application, not all. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0031] According to the first aspect of the present application, a ship design method based on ship type flexible customization is first provided, as shown in the following steps: Figure 1

[0032] S1, constructing a ship digital design ontology for a target ship type: according to the modular design construction characteristics of different ship types, constructing a ship type-based digital design ontology framework, defining the target ship design module division principle, and the correlation between modules. The module hierarchical relationship diagram of the knowledge graph is regarded as a tree, and the divided module nodes are regarded as the nodes of the tree.

[0033] Specifically, according to the design modules divided according to the construction mode and design principles and other elements, a graph module division ontology framework is constructed, which is a digital design ontology framework. Taking a certain type of liquefied gas ship as an example, the first-level nodes of the ontology are mainly regional nodes, including the bow region, the stern region, the upper building region, the cargo hold region, etc. The second-level nodes are mainly specialties, including structure, machinery, electrical, etc. The third-level nodes are mainly modules, systems, functional units, etc. and further node division, which are defined according to design requirements. The digital design ontology framework is not limited to the above node organization method, and can be flexibly defined according to actual application requirements.

[0034] S2, based on the ontology framework constructed in S1, the relationship mapping between the digital design ontology and the module function sub-ontology is constructed, and it is judged whether the existing module ontology meets the digital design requirements of the target ship type. The module function sub-ontology is mainly the ship module design ontology that has been constructed. This sub-ontology expresses the collaborative design relationship, knowledge rules, intelligent design tools, etc. of the target module, and in the digital design process, the design tools are mainly pushed and the related knowledge rules are reasoned according to the sub-ontology, and the design tools are driven to perform rapid design.

[0035] Based on the ontology framework constructed in S1, it is judged whether the existing module function sub-ontology meets the digital design requirements of the target ship type. For example, in the "water supply system" sub-ontology of "certain type of ship-machinery region-machinery specialty-water supply system" in the digital design graph that has been constructed, whether it meets the design requirements of the certain type of liquefied gas ship currently defined, and whether the corresponding module function sub-ontology exists according to the characteristics of the target ship type.

[0036] S3, if the existing regional function sub-ontology in S2 meets the design requirements, then step S4 is performed; if it does not exist or cannot meet the current ship design requirements, then the corresponding regional function sub-ontology is reconstructed.

[0037] ​If the function sub-module ontology referenced meets the current module design requirements, for example, the "water supply system" sub-ontology defines the modeling design requirements required for the target ship type design, such as pipeline modeling, pipe accessory modeling, and support modeling, etc. First, the target ontology is instantiated, and then the fusion of the referenced module function sub-ontology and the target ship type ontology is completed through the knowledge graph fusion technology. The referenced module function sub-ontology can be the smallest node of the ship digital design ontology, or a sub-graph node, which is referenced according to the design tool requirement satisfaction.

[0038] If the module function sub-ontology in S2 does not exist or cannot meet the current ship type design requirements, the corresponding module function sub-ontology is reconstructed. Reconstructing the corresponding module function sub-ontology includes creating a module function sub-ontology, taking each professional three-dimensional design object in the ship module as the basis for ontology construction, and constructing a knowledge graph for specific module design. The module function sub-ontology associates discrete design tools, knowledge rules, and design objects.

[0039] For example, compared with a container ship, a liquefied gas ship has a large difference in cargo hold area design content and design method, and a module function sub-ontology needs to be defined for the target ship type cargo hold area, for example, the sub-ontology of the liquid tank area in the cargo hold area needs to define all design object nodes. The creation of the module function sub-ontology mainly takes the three-dimensional design objects of each professional such as ship, machinery, and electrical in the module as the basis for ontology construction, and constructs a knowledge graph for specific module design. The sub-ontology mainly associates discrete design tools, knowledge rules, and design objects.

[0040] S4, the reconstructed module function sub-ontology of S3 is fused with the ship digital design ontology of the target ship type. This includes constructing the association mapping between related graphs, and the same design module function sub-ontology can be fused with multiple ship digital design ontologies. The related graphs include the sub-graph related to the design rules, the graph corresponding to the module function sub-ontology, and the main graph constructed based on the design ontology.

[0041] S5, discrete design tool mapping relationship reconstruction: the design tool in the application changes the traditional integrated design tool mode, and can construct packaged design tools according to different professions, different design objects and different intelligent design needs. All design tools exist in the design platform system in an independent and discrete manner, and can be searched in the system through retrieval. After completing the fusion of the S4 ship type design ontology and the design module function sub ontology, the discrete design tool is mapped and associated with the knowledge graph ontology that has been fused in S4, the relationship between the knowledge graph design tool and the object is created, and in the mapping relationship creation process, the same module, the same design object and different ship type design tools are considered, so that the same module function sub ontology can consider multiple ship type design needs. In summary, through the corresponding design tool, the design tool and the graph are related and mapped to realize the specific design function point.

[0042] The mapping relationship is constructed in the following way: first, find the automatic reasoning matching, and see if the appropriate design tool unit can be found. If no matching is found, it is established manually. Specifically, after completing the construction of the target ship type design ontology, the mapping relationship between the discrete design tool and the graph is created. All tool units exist in the design platform system in the form of a tool set resource library. In the creation process, the operator creates the mapping relationship between the tool unit and the corresponding node of the graph by relationship extraction matching. If the association relationship is wrong, the corresponding tool unit is obtained by searching in the tool set resource library and associated with the graph.

[0043] S6, judge whether the design tool set associated with the module function sub ontology meets the design requirements; if not, define the discrete design tool, and if it meets the requirements, go to step S7.

[0044] Each module function sub ontology is associated with multiple design tools of each profession, and it is necessary to judge whether the currently associated design tools are fully covered and whether the associated design tools meet the design application requirements of the target ship type.

[0045] The judgment basis for whether the design tool set meets the requirements is whether all design objects contained in the regional function sub ontology are supported by corresponding design tools, and whether the number of object-relation-tool triples in the module sub graph constructed by the module function sub ontology is consistent with the number of design objects.

[0046] Specifically, in the design platform system, through automatic detection function, it is detected whether all design objects of the target ship type are associated with design tools, and whether the design tools can be effectively started and executed in simulation running, for example, if the system simulation running finds that "a certain cabinet unit module" in "a certain ship-cabin area-mechanical professional-a certain cabinet unit module" in the graph has no corresponding design unit, it is automatically prompted.

[0047] If the corresponding design tool is missing in the judgment module or does not meet the design requirements of the target ship type, the corresponding design function design tool is developed and defined, which needs to meet the design requirements based on knowledge rule modeling driven, and can be flexibly configured and associated in the design platform. Based on the design requirements, the developed design tool is related to the knowledge graph through the S5 step.

[0048] Specifically, if the relevant design unit or design tool is found to not meet the design requirements of the target ship type during system simulation, the design tool of the corresponding design object is developed and managed in the library based on the design platform system, and then the relationship with the knowledge graph is created through the S5 step.

[0049] S7, based on the constructed digital design ontology and the design tool set associated with each module of the target ship type, the target ship type design driven knowledge rule mapping relationship is reconstructed:

[0050] Based on the constructed digital design ontology framework and the design tool set associated with each module of the target ship type, the relationship between the design ontology, the design tool and the knowledge rule is created, the knowledge rules in the knowledge rule library are mapped to the design tools in the design tool of the corresponding module function sub-ontology of the target ship type, and the mapping relationship is corrected. The knowledge rule mapping relationship reconstruction based on the target ship type design is realized. In the knowledge driven rule relationship creation process, the compatibility of the same module function knowledge driven of different ship types needs to be considered. The design ontology refers to the ontology constructed in S1 step, which is the ontology of a certain type of ship. The design tool refers to the smallest program module that meets the design requirements, and the design tool set refers to the combination of design tools applied to meet a certain design task.

[0051] Specifically, if the design tool associated in the graph cannot be effectively associated with the knowledge rule in the knowledge base, the mapping relationship between the knowledge rule in the knowledge rule library and the design tool in the corresponding module function sub-ontology of the target ship type is created or corrected in batches through semantic definition and relationship extraction.

[0052] S8, judge whether the knowledge rule meets the design driven requirements of all graph node design tools, if not, maintain the knowledge of the design knowledge base, and complete the reconstruction of the mapping relationship between the design tool and the design tool through the S7 step.

[0053] After completing the design driven knowledge rule mapping relationship reconstruction in S7 step, it is necessary to judge whether the associated knowledge rule is effectively associated with the design tool associated in the graph, and whether the associated knowledge rule meets the digital design knowledge driven requirements of the corresponding design tool.

[0054] If the knowledge rules associated with the relevant design tools do not meet the modeling knowledge requirements of the design tools, the knowledge maintenance of the design knowledge base is performed so that the knowledge expression in the knowledge base meets the design requirements of the design tools, the effect of intelligent pushing and driving the design tools for intelligent design is achieved, after the knowledge maintenance, the reconstruction of the mapping relationship between the design tools and the design tools is completed through the S7 step.

[0055] Specifically, after completing the S7 step of mapping relationship reconstruction of the design driving knowledge rules, the tool units are simulated and called in batches in the design system platform, it is judged whether the design tools can be effectively started, if not, the error is automatically prompted, and if the associated knowledge is found to have errors in the design application process, the knowledge rule base is manually maintained.

[0056] If the functional unit simulation cannot be driven by the associated knowledge rules, or the associated rules are found to be incorrect during the design process, the knowledge rules in the knowledge base are maintained, the knowledge rule base maintenance mainly supplements and optimizes the knowledge rule atlas, which meets the current target ship design requirements, and also does not affect the application of other ship knowledge, after the knowledge maintenance, the reconstruction of the mapping relationship between the design tools and the design tools is completed through the S7 step.

[0057] S9, flexible customized design tool set visualization pushing display based on knowledge atlas:

[0058] After completing the above design knowledge atlas construction taking the target ship as the ontology, based on the constructed knowledge atlas, the design tools in the ship digital design system platform are visualized in the form of atlas taking the atlas ontology as the main display framework, according to different professions, different permissions, different design objects, etc., the design tools for display and pushing are limited, the design personnel can display the corresponding tool set atlas according to the actual application requirements, and the design tools can be quickly selected and found through the guided display of the atlas.

[0059] Specifically, the flexible customized design tool visualization pushing design system platform of the knowledge atlas is created, in the design platform, according to different professions, different permissions, different design objects, etc., the specified tool set is displayed to the user in the form of atlas guide, the design personnel can quickly complete the modeling design of the corresponding design module according to the atlas guide prompt.

[0060] S10, the design tool quickly calls and realizes intelligent design based on knowledge driving: the flexible customized design tool set based on the knowledge graph is visualized and pushed to the design system platform, the design personnel opens the design object, the design tool set is pushed to each design personnel in the form of graph guide, the design tool is matched with the knowledge rule based on background reasoning, and the effect of efficient and intelligent digital design is realized. For example: when the marine engine designer is responsible for the design of a certain pipeline system in the cabin area, opens the corresponding design object in the design platform, and pushes the design tool set in the area in the form of graph guide in the design interface, including: system pipeline automatic arrangement, equipment accurate positioning and other related design tool sets, when the system pipeline arrangement design tool is selected, the system is matched with the modeling rule based on automatic reasoning of the knowledge graph, and the modeling driving based on the knowledge rule is realized through the design tool, so that the rapid and accurate arrangement of the target pipeline system is realized.

[0061] During the ship digital design process of the designer, based on the constructed knowledge graph, the corresponding design module can be automatically matched according to the design content, and the design tool corresponding to the module is pushed according to the design stage, the design professional, the operator information and the like. The designer only needs to select the corresponding module design object in the design process, and the module design tool set can be automatically pushed out. After the corresponding design tool is selected, based on the constructed knowledge graph, the knowledge rule matched with the current design tool and design environment is automatically reasoned and called, and the intelligent design based on knowledge driving is realized through the design tool. After the designer adjusts the design result, the associated knowledge content in the knowledge graph can be updated synchronously, so that the next design process is more accurate.

[0062] The application changes the traditional ship three-dimensional design software design mode, innovatively puts forward a ship design method and system based on ship type flexible customization, realizes flexible customization based on different ship type design tools by organically integrating discrete design tools and knowledge graph in the design platform system and visualizing display, and realizes accurate reasoning of digital design knowledge rule demand based on knowledge graph. The designer can push the design tool required by the design personnel according to the user demand in the design process, and also provides an effective means for intelligent design. The application not only can improve the utilization efficiency of the design tool, but also can improve the knowledge reuse rate, avoid the collection and search of design data, and effectively improve the design efficiency and design quality. In summary, the application effectively overcomes many shortcomings in the prior art, and has high industrial utilization value.

[0063] Preferably, the S2 step references an existing module function sub ontology, and after instantiating the ontology object, fusing and associating the design tool and the knowledge rule with the target ship type ontology, other ship types do not affect the reference of the ontology object, so that different ship types can reference the same module function sub ontology.

[0064] Preferably, the mapping relationship reconstruction in the S5 and S7 steps can be created in batches through relationship extraction.

[0065] Preferably, the judgment basis for whether the tool set meets the requirement in the S6 step is whether all design objects contained in the module function sub-ontology are supported by corresponding design tools, and whether the number of object-relation-tool triples in the regional sub-atlas is consistent with the number of design objects.

[0066] Preferably, in the knowledge rule mapping relationship reconstruction in the S7 step, the knowledge rules to be reconstructed are mainly optimized in the knowledge rule library, and the knowledge rule reasoning range of the knowledge atlas is automatically expanded, so that it not only meets the design requirements of the target ship type, but also does not affect the design driving requirements of the associated ship type.

[0067] Preferably, the judgment basis for whether the knowledge rule meets the design tool knowledge driving requirement in the S8 step is whether the design tool can verify whether there is corresponding driving rule knowledge by simulation, and whether the driving design tool knowledge rule is based on atlas to realize intelligent reasoning.

[0068] The application innovatively proposes a ship design method based on ship type flexible customization, which realizes flexible customization based on different ship type design tools and realizes accurate reasoning of digital design knowledge rule requirements based on a knowledge atlas by organically integrating discrete design tools and the knowledge atlas in the design platform system and visualizing the display.

[0069] The method of the application can customize modular intelligent design tools according to different module design requirements in the ship modular design process, form a design tool resource library, associate the design requirements with the atlas and the knowledge rule library, and push the design tools required by the design personnel according to the user requirements in the design process.

[0070] The design method solves the problem of low integration of traditional design methods and intelligent design methods, realizes knowledge-driven modular rapid design, and provides an effective means for intelligent design.

[0071] The design method and system effectively integrate the design process and knowledge, which not only improves the utilization efficiency of the design tools, but also improves the knowledge reuse rate, avoids the collection and search of design data, and effectively improves the design efficiency and design quality.

[0072] According to the second aspect of the application, a computer storage medium for implementing the above method is also provided. The computer storage medium stores a computer program, which is executed by a processor to implement the ship design method based on ship type flexible customization.

[0073] Preferably, the storage medium includes: ROM, RAM, a magnetic disc, a U disk, a memory card, or an optical disc, and the like various media capable of storing program codes.

[0074] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. The present application can have various modifications and changes for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
