Description

Technical Field

[0001] The present invention relates to the technical field of ship design, and in particular to a data migration method for a digital model of a trailing suction hopper vessel in the operation and maintenance direction. Background Art

[0002] The digital ship 3D model is a ship design solution based on computer technology. It can intuitively display the shape, internal structure and layout of various equipment of the ship, providing great help for ship design, construction and operation and maintenance. By using the 3D model, designers can design ships in a virtual environment, which can greatly reduce the time and cost consumption in the physical production process, and can also timely discover and correct possible problems in the design process. In addition, the digital ship 3D model can also be used for the simulated operation and performance analysis of the ship. By simulating the 3D model, the performance data of the ship under different working conditions can be predicted, providing a scientific basis for the optimized design and operation of the ship. The research and application of the digital ship 3D model can not only improve the efficiency and quality of ship design, but also help promote the technological progress and development of the shipbuilding industry. It can also provide the necessary basic model data for the later owners to build a digital ship platform for "operation, management and maintenance".

[0003] From the perspective of shipbuilding, digital ship 3D model technology has changed the traditional manual drawing and sample making methods, and achieved more accurate design through 3D modeling. This not only improves the accuracy of shipbuilding, but also shortens the construction cycle and reduces costs. At the same time, the technology also optimizes the production process, simulates and optimizes the shipbuilding process, so that production efficiency and resource utilization have been improved. Manufacturers can adjust the process flow according to the simulation results, reduce waste and repetitive labor, and realize lean management of the production process. In addition, by monitoring quality data, problems can be discovered in time and measures can be taken to ensure that the quality of shipbuilding meets the standard requirements.

[0004] From the perspective of ship operation and maintenance, with the continuous advancement of science and technology, this technology has penetrated into the shipping field and brought about revolutionary changes. First of all, the core advantage of digital ship technology lies in real-time monitoring capabilities. Traditional ship management often relies on manual inspections and experience-based judgments, while digital models can achieve real-time monitoring of various ship operating parameters through precise sensor networks and data analysis systems. Secondly, this technology can also provide intelligent early warning functions. Through in-depth mining and analysis of ship operation data, the system can predict potential failure risks and issue early warnings. This targeted management method not only improves the reliability of ships, but also significantly reduces operation and maintenance costs.

[0005] With the application of digital models on trailing suction hoppers, it is often the case that the digital 3D model results of the output production process cannot be fully delivered to users. Users are unable to manage ship facilities in a more intuitive way during the later operation process, which affects the later operation efficiency.

[0006] Therefore, the present invention proposes a data migration method for a digital model of a trailing suction hopper vessel in the operation and maintenance direction to solve the above problems. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a data migration method for a digital model of a trailing suction hopper vessel in the direction of operation and maintenance, so as to realize information sharing of the product in the two important stages of construction and operation and maintenance, and to improve the overall operation and maintenance efficiency of users.

[0008] In order to solve the above technical problems, the technical solution of the present invention is: a data migration method of a digital model of a trailing suction hopper vessel in the operation and maintenance direction, the innovation of which is: comprising the following steps: Step 1, 3D modeling: Use 3D modeling software to create a high-precision, high-fidelity 3D model of the ship, and decompose the ship construction process by region, operation type and operation stage, divide it into several manufacturing levels, and perform 3D modeling design on the operation objects of each manufacturing level; Step 2: 3D model presentation: Use 3D modeling software to create models of the hull, equipment, piping, and outfitting, and visually present the internal structure and spatial layout of the hull, so that designers in various professional fields can view, evaluate, and modify the models in their corresponding professional fields; Step 3: Digital 3D modeling of the whole ship: The whole ship is designed according to the design of the hull, piping, equipment and outfitting. When designing the whole ship, the model data information and assembly plan are defined. The models of each discipline are required to meet the design and specification requirements, the hull components do not interfere with each other, and the geometric dimensions and positioning dimensions are accurate. The layout of the piping, outfitting, electrical and HVAC must meet the functional and applicability requirements to ensure the integrity of each discipline model. Step 4: Digital 3D model migration: Use professional shipbuilding software to generate ship models, export model data for migration, and output formatted model data migration in the form of secondary development that matches the model. The detailed process is as follows: Step 4-1: When migrating the digital 3D model, the migrated model is divided into four categories: hull, piping, equipment, and outfitting. The four categories include all models generated during the ship construction phase, including: The hull model is a ship structure, which is composed of wall plates and frames. In the hull model, a single plate is composed of two face pieces, and the distance between the two face pieces is the thickness of the single plate wall. The piping model consists of all the pipes in the ship. The piping model is migrated according to the category. For pipes with a diameter of more than 100 mm, the wall thickness must be reflected, that is, the hollow cylindrical surface. The wall thickness data of all pipes is migrated through the model table; The equipment model consists of all the equipment on the ship. The minimum requirement for equipment model migration is to migrate the appearance 3D model. For the equipment that needs to be disassembled and repaired in the management of the trailing suction hopper, the parts assembly model is migrated; Outfitting models include all models except ship structure, pipes, equipment, and profiles; Step 4-2: Determine the accuracy of the model to be exported from the professional shipbuilding software according to the hierarchical display and the current office facility configuration level requirements; Step 4-3: According to the naming rules of the production design model, the whole ship model is exported in batches and classified. The exported model has global coordinates in the whole ship to avoid position errors that may cause model inaccuracy; Step 4-4, the three-dimensional model auxiliary information data is migrated in the form of a database. The table of the information database includes two key fields and other fields. The two key fields are the category name reflecting the model type and the model component name reflecting the usage information. The other fields are descriptions of the main parameters of the equipment.

[0009] Furthermore, the pipe system model in step 4-1 uses a solid cylinder for pipes with a diameter of less than 100 mm.

[0010] Furthermore, in step 4-1, the migration format of the device class model is an STP format.

[0011] Furthermore, the origin of the global coordinates in step 4-3 is the intersection of the rudder stock, the baseline and the midship line.

[0012] Furthermore, when the whole ship model is classified and output in batches in step 4-3, the hull model is exported in batches according to the segment division diagram for each segment, the piping model and the outfitting model are exported in two batches, segment and region, and the equipment model is exported according to the professional classification of machinery, outfitting, electrical, and dredging design.

[0013] Furthermore, the main parameters of the equipment in step 4-4 include specifications, materials, and surface treatment.

[0014] Furthermore, when migrating the digital three-dimensional model in step 4, the professional shipbuilding software TRIBON is used to generate the ship model, and the model data is exported in DXF format for migration.

[0015] The advantages of the present invention are: (1) The data migration method of the present invention realizes the effective application of the shipyard construction phase model in the owner's operation and maintenance phase, and seamlessly integrates the auxiliary information of the model in the production design into the digital ship operation and maintenance system. By unifying the naming conventions of the construction phase model, it ensures that the operations such as retrieval and screening of the model in the ship operation and maintenance phase are barrier-free and easy to read, thereby realizing information sharing of the product in the two key stages of construction and operation and maintenance, and ultimately achieving the goal of improving the user's operation and maintenance efficiency.

[0016] (2) The data migration method of the present invention uses secondary development to import the digital model obtained by comprehensive and detailed modeling of the shipyard into the digital technology of the owner's platform, covering all aspects of the ship's hull, piping, outfitting, and equipment, and can achieve all-round and no-dead-angle data migration. This digital migration technology can truly reflect the actual structure and details of the ship and provide accurate data support for ship design, modification, and maintenance. It not only enables the owner to perform operations such as rotation, scaling, and movement, but also allows the owner to understand the structure and details of the ship from different angles and levels. In addition, it can facilitate the owner to formulate and optimize ship design, modification, and maintenance plans. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0021] Example This embodiment provides a method for data migration of a digital model of a trailing suction hopper vessel in the operation and maintenance direction, such as Figure 1 As shown, the following steps are included: Step 1: 3D modeling: Use 3D modeling software, such as TRIBON, CATIA and SolidWorks, to create a high-precision, high-fidelity 3D model of the ship, and decompose the ship construction process by region, operation type and operation stage, and divide it into five manufacturing levels, such as Figure 2 As shown, the three-dimensional modeling design is performed on the work objects at each manufacturing level, namely, the parts level, assembly level, segment level, slipway area level and dock area level; Step 2: 3D model presentation: Use 3D modeling software to create models of the hull, equipment, piping, and outfitting, and visually present the internal structure and spatial layout of the hull, so that designers in various professional fields can view, evaluate, and modify the models in their corresponding professional fields, thereby improving design quality and efficiency. Step 3: Digital 3D modeling of the whole ship: The whole ship is designed according to the design of the hull, piping, equipment and outfitting. When designing the whole ship, the model data information and assembly plan are defined. When 3D digital modeling is performed, it is required that the models of each discipline meet the design and specification requirements, the hull components do not interfere with each other, and the geometric dimensions and positioning dimensions are accurate. The layout of the piping, outfitting, electrical and HVAC must meet the functional and applicability requirements, ensure the integrity of each discipline model, realize the integrated process of design, production and management, and prepare for the later migration of digital models. Step 4: Digital 3D model migration: Use professional shipbuilding software TRIBON to generate the ship model, export the model data in DXF format for migration, and output the formatted model data migration in the secondary development form that matches the model. The detailed process is as follows: Step 4-1: When migrating the digital 3D model, the migrated model is divided into four categories: hull, piping, equipment, and outfitting. The four categories include all models generated during the ship construction phase, including: The hull model is a ship structure, which is composed of wall plates and frame materials. In the hull model, a single plate is composed of two face pieces, which is not a solid model. The distance between the two face pieces is the thickness of the single plate wall. The piping model consists of all the pipes in the ship. The piping model is migrated according to the category. For pipes with a diameter of more than 100 mm, the wall thickness must be reflected, that is, a hollow cylinder. For pipes with a diameter of less than 100 mm, a solid cylinder is used. The wall thickness data of all pipes are migrated through the model Excel table; The equipment model consists of all the equipment on the ship, including mechanical equipment and electrical equipment. The minimum requirement for equipment model migration is to migrate the appearance 3D model. The migration format is preferably STP format. For equipment that needs to be disassembled and repaired in the management of trailing suction hoppers, the parts assembly model is migrated; Outfitting models include all models except ship structure, pipes, equipment, and profiles; Step 4-2: Determine the accuracy of the model to be exported from the professional shipbuilding software according to the hierarchical display and the current office facility configuration level requirements; Step 4-3: According to the naming rules of production design models, classify and batch output the whole ship model. The exported model has global coordinates in the whole ship. The origin of the global coordinates is the intersection of the rudder, baseline and midship line. The coordinate system positioning of all models exported in batches must be completely corresponding to avoid position errors that cause model inaccuracy; The production design model naming rules here take the pipe system naming rules as an example: The piping system name consists of two parts: the first part is the pallet name, and the second part is the model name. The two parts are separated by “—”. The pallet name includes the professional, stage, section or total section or area or unit name listed from left to right. The model name includes the system name and pipeline name listed from left to right, for example: T9E01-WA56, where T stands for machine installation, 9 stands for regional bulk, E01 stands for regional name, WA is the system name (working air system-WORKING AIR), and 56 is the pipeline serial number.

[0022] When the whole ship model is exported in categories and batches, the hull model is exported in batches according to the section division diagram for each section, the equipment model is exported according to the professional categories of machinery, outfitting, electrical, and dredging design, the piping model and the outfitting model are exported in two batches, section and area. When exporting the piping model, the pipe color needs to be processed according to the piping schematic diagram and standard classification, and the cables of the model need to be divided into medium voltage, variable frequency, and low voltage cable path colors according to the electrical schematic diagram.

[0023] In order to reduce the inefficient use of computer resources, the models of the hull at all levels can be merged, and measures can be taken to merge the segmented faces of the initial model exported in DXF format, that is, the same plane needs to be a separate plate 3D model.

[0024] Step 4-4, the three-dimensional model auxiliary information data is migrated in the form of a database. The table of the information database includes two key fields and other fields. The two key fields are the category name reflecting the model type and the model component name reflecting the usage information. The other fields are descriptions of the main parameters of the equipment, which include specifications, materials, and surface treatment.

[0025] In the database, for each subdivided single component, there should be a unique root naming method to ensure that it can be read by the database and that the specific component can be quickly located through database query; and on the basis of the root naming method, the non-geometric information of the component's name, category, material, and performance, as well as the geometric information of length, width, area, and coordinates should be attached. The three-dimensional model of the ship should be classified and divided according to the structure, and there should be an overall tree diagram for each profession, level, and batch, and its structural naming should reflect the hierarchical requirements. The migrated database should have the identification methods of "root naming method" and "unique ID" and can be attached to the ship model, ship geometric data, and ship non-geometric data.

[0026] The data migration method realizes the effective application of the shipyard construction phase model in the owner's operation and maintenance phase, and seamlessly integrates the auxiliary information of the model in the production design into the digital ship operation and maintenance system. By unifying the naming standards of the construction phase model, it ensures that the retrieval and screening of the model in the ship operation and maintenance phase are barrier-free and easy to read, thereby realizing information sharing of the product in the two key stages of construction and operation and maintenance, and ultimately achieving the goal of improving the user's operation and maintenance efficiency.

[0027] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
