Detailed Description
The present disclosure is further illustrated by way of examples below, but is not thereby limited to the scope of the examples described.
The current ship data management mode is generally based on the data management provided by a three-dimensional design software platform, is limited by the data management mode of the three-dimensional design software by taking a model as a carrier, cannot meet the requirement of deepened data management, has large data structure difference, cannot be compatible, has non-uniform data specification among platforms, and has data island and business conflict.
In view of the above, the present disclosure provides a method, a system and a data service platform for managing ship data, so as to solve the problems that the existing three-dimensional design software platform has large data structure difference, cannot be compatible, and has non-uniform data specification and data island and business conflict between platforms.
The ship design is a core link in the ship product construction period, is a zero workshop for ship construction, and the design period accounts for 60% -70% of the whole period. The ship design is mainly divided into a plurality of stages of preliminary design, detailed design, production design and the like, wherein the production design has very important positions, and the accuracy of basic data of ship body and outfitting each professional modeling work directly influences the subsequent ship production and construction. The ship design stage can generate a large amount of product data, most shipyards in China lack unified management of the design data at present, the design data is mainly delivered to the back-pass through drawings and files, the back-pass production department can hardly acquire complete and accurate design data, and a plurality of troubles are brought to purchasing and production preparation.
In recent years, various domestic shipyards always seek a scheme for uniformly managing a large amount of product data in the design process, so that the process tracking and information feedback of design and manufacture are realized, the design quality is promoted, and the design cost is reduced. In the face of complex ship-shaped or huge system engineering, such as a large-scale mail ship, the production design has the characteristics of long design life cycle and huge design data volume, and the defect that the traditional data management mode cannot meet the service requirement is more remarkable, so that the research, development and application of the digital shipbuilding technology are required to be greatly advanced, a full-dimensional structured product data pool is established, digital delivery is realized, the ship design quality is improved, and the design cost is reduced.
Example 1
Referring to fig. 1, in a specific embodiment of the present disclosure, there is provided a management method of ship data, the management method including the steps of:

After the establishment of each professional structured data model in each dimension is completed, ship data corresponding to the ship models in the plurality of three-dimensional design software platforms are obtained, the obtained ship data are subjected to data division according to each dimension, the data corresponding to each professional structured data model in each dimension are stored into the corresponding structured data model, and the conversion from the whole ship three-dimensional model data to the structured data model is realized by synchronizing the three-dimensional design software model data, so that the integration and classification of the ship data in the plurality of three-dimensional design software platforms are realized.
In a specific embodiment, the data of different structural levels in the new ship data are respectively stored into the corresponding structured data model by adopting a synchronous mode of instant synchronization and/or timing synchronization.
Specifically, corresponding data acquisition tools are respectively developed aiming at different three-dimensional model design platforms, and the data integrity of the data pool is ensured by adopting a mode of combining an instant synchronization mode and a timing synchronization mode. In a specific embodiment, different data acquisition modes are adopted for different three-dimensional design software platforms so as to adapt to the data acquisition requirements of the different three-dimensional design software platforms. For example, in a closed three-dimensional design software database, for example, a periodic scanning mode is adopted for a Tribon M3 ship design building software integrating CAD/CAM/MIS and an AVEVAMarine integrated software which provides a series of solutions, loading items and single-machine application programs by taking objects as centers; in the three-dimensional design software using the commercial database, for example, for an Intergraph Smart 3D three-dimensional design software using the commercial database MS SQL or Oracle as a base data platform and using open Visual Basic and net technologies as development means, data subscription and data triggering modes are adopted to detect data changes in real time. In order to ensure the real-time and accurate data of the data pool, a data version is established by taking a day as a unit, so that the data can be traced back and can be traced. In addition, related link data, such as data of a planning management system, a supply chain system, a production management system, a quality management system and the like, is synchronously collected so as to perfect the data dimension in the original data layer of the full-dimension structured data pool.
In the data acquisition process, the cloud primary methodology is adopted in the embodiment due to the reasons of huge data volume, data damage and the like of the three-dimensional design software, and the distributed acquisition means of intermediate product dimensions such as a total section, a subsection and an area are adopted, so that the expandability, elasticity and observability of the acquisition process are promoted, and the efficiency and the flexibility of model data conversion are improved.

Therefore, in order to improve the availability of the ship data, in this embodiment, the middle data layer of the data pool is constructed, and the ship data in the original data layer is integrated and reconstructed to obtain the integrated and reconstructed ship data, for example, by combining with shipbuilding professional knowledge, combing related rules, reconstructing and mining product data, deepening the data structure, and expanding the attribute of the data model; recoding the product data by combining with a shipyard coding rule; reconstructing a data structure taking intermediate products such as a headquarter, a section, an area, a unit and the like as units by combining a construction policy; combining the space range division of the region and the like to reconstruct a space region range data structure; excavating a model attribute structure by combining a construction process; and combining the association relation between the design data and link data such as planning, construction and the like, expanding the life cycle of the product data, and forming a full life cycle data structure from the design, construction to the ship delivery.
