The specific embodiment

First by integrating boats and ships three Dimensional CAD Design technology and PDM Collaborative Management, set up boats and ships concurrent collaborative design-build platform, integrated LNG ship design and as-built information, and in LNG ship design manufacturing process, synchronous formation be take the integrated data base of ship components 3D modelling as carrier recording ship design manufacturing information.These digital informations are further perfect, through suitable functions expanding, set up the visual operation management platform based on three-dimensional virtual scene, for the training of LNG ship operation provides valuable simulation environment, can meet the information system requirement of daily operation management simultaneously.

Boats and ships Digital Integrated Management embodiment of the method for the present invention is at the system logic figure of ship design and fabrication phase as shown in Figure 1, and the embodiment of the present invention provides a kind of digitalisation boats and ships integrated management method and system of Facing Digital ship design Application in manufacture present situation.First system needs by boats and ships three Dimensional CAD Design technology and PDM Collaborative Management, set up boats and ships concurrent collaborative design-build system, contain from ship design project and prove project verification, ship design and construction phase, embodied modern ships and manufactured and designed high quality and high efficiency new concept.The boats and ships concurrent collaborative design that the present invention takes is based on Product Data Management Technology and concurrent engineering method.The first step is first to implementing concurrent collaborative design and management from Ship Conceptual Design, technical design, detail design, the design of virtual sample ship, Production design to completion each design phase of design and each design specialist.Adopt distributed data base technique to realize the data that produce in above-mentioned design content, process are stored, managed and recycle, by Internet network struction boats and ships Collaborative Design network, provide the unified technical operation network platform for above-mentioned every content simultaneously.Second step is realized and is applied as core with three-dimensional grid model structured database, and realizes the parallel monitoring in real time to design-build process by various visualization tools, fundamentally changes the mode that ship design is built.Main manifestations is: set up a network ship collaborative design construction work pattern; The designer in each stage and construction personnel can utilize easily visualization tool to realize and exchange smoothly, and that not only can carry out design effort assigns, carries out tracking and the work quantitative statistics of publishing picture; Also can realize Electronic Design file centralized and unified management and guarantee its version and access rights controlled.Can guarantee validity and the conformability of data simultaneously.By means such as Three-dimensional Design Software, visualization technique and actv. Concurrent Controls, improve that boats and ships are overall, between each design specialist and the communication and coordination efficiency between design division and construction department, reducing design does over again, guarantee the harmony in design process, ensure carrying out smoothly of ship building work.The electronics label of design-build file application Network Based be can realize in addition and flow process, the efficiency and the standardization that further improve design-build flow process examined; The a large amount of technological documents that produce in product design process and data are carried out to actv. management, thereby guarantee validity, the conformability of design information.Utilize database semantic technology to realize effective tissue and the access to product data and relevant documentation, the incidence relation between maintenance items data, can significantly improve Information Retrieval Efficiency.

Boats and ships Digital Integrated Management embodiment of the method for the present invention is at the system logic figure of shipping transport and management phase as shown in Figure 2, and the embodiment of the present invention provides a kind of digitalisation boats and ships integrated management method and system of Facing Digital ship design application present situation.By integrated LNG ship design and as-built information, and in LNG ship design manufacturing process, synchronous formation be take the integrated data base of ship components 3D modelling as carrier recording ship design manufacturing information.These digital informations are further perfect, through suitable functions expanding, set up the visual operation management platform based on three-dimensional virtual scene, for the training of LNG ship operation provides valuable simulation environment.This simulation environment and its corresponding database system are further expanded, built Ship Operating Decision Support System, can be for leadership provides information for supporting some decision when meeting the information system requirement of daily operation management.In order to realize above-mentioned target, first need to adopt the three-dimensional grid model reconstruction technique based on pattern understand to realize building of boats and ships virtual emulation environment, and to adopt Data Segmentation and dynamic dispatching be main solution, realize the visualized data tissue of extensive three-dimensional scenic.

Boats and ships Digital Integrated Management embodiment of the method data structured management of the present invention realizes figure as shown in Figure 3, and the embodiment of the present invention provides a kind of three-dimensional modeling data storehouse consisting of model bank, model relevant documentation, classification scheme and management software four major parts.Wherein model bank has been stored three-dimensional modeling data, and various relevant to model of model relevant documentation record manufacture and design information.Classification scheme has provided the logical organization relation of model in storehouse, and management software carries out integrated management to model bank and classification scheme, for external user and application program provide access interface.Because the shipping industry scale of construction is huge, in 3 d model library, conventionally comprise a large amount of 3D modellings, if completely cumbersome by the retrieval and the administrative model operation that realize by hand in daily attention, design a model bank management software and contribute to streamlining management, will greatly raise the efficiency.The function of this management software specifically can comprise 3 aspects below: first can realize classification scheme editting function: owing at present the automatic classification technology of model also not being occurred, thereby proceed from the reality, still adopt the way of manual sort, so this software should allow, user creates easily, editing classification table.The programmatic access interface of 3 d model library can be provided in addition.Because model bank has adopted comparatively complicated organizational structure, therefore, when program need to conduct interviews to model bank, this software should provide DLL (dynamic link library), allows program go the arbitrary model in Access Model storehouse.Model import feature: both can import single model, and also can import a collection of model.User only need to select the target model that need to import simply, and system just can, automatically for it distributes numbering, generate thumbnail and additional information supporting paper.

It should be noted that, the contents such as the information interaction between said apparatus and intrasystem each unit, implementation, due to the inventive method embodiment based on same design, particular content can, referring to the narration in the inventive method embodiment, repeat no more herein.

One of ordinary skill in the art will appreciate that all or part of step in the whole bag of tricks of above-described embodiment is to come the hardware that instruction is relevant to complete by program, this program can be stored in a computer-readable recording medium, storage medium can comprise: read-only memory (ROM) (ROM, Read Only Memory), random access memory (RAM, Random Access Memory), disk or CD etc.
