Traditional ship pipe and outfitting production design relies on manual experience, which has problems such as large workload and easy errors. With the development of computer technology, computer-aided design technology is widely used in ship design. However, existing computer-aided design technology tools still face problems such as low design efficiency, insufficient accuracy, and difficult data management when dealing with complex pipe and outfitting assembly design.

[0003] At present, the industry-university-research cooperation between domestic universities, scientific research institutions and enterprises is gradually strengthening, jointly promoting the development of ship pipe fittings parametric modeling technology. In recent years, some independently developed ship pipe fittings parametric modeling software have also appeared in China, such as PipeCAD; continuous progress has been made in the parametric modeling technology of ship pipe fittings, and basic parametric modeling functions have been realized, and have been applied in some specific fields and projects. However, compared with foreign advanced technologies, there is still a certain gap in modeling accuracy, efficiency, complexity, etc. For some special-shaped pipe fittings on ships, domestic parametric modeling technology may not be able to achieve fast and accurate modeling.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A parametric modeling system for ship pipes and outfitting, characterized in that the system comprises a data extraction module, a parametric modeling module, a visual display module and a data management module; The data extraction module imports preliminary design data including equipment parameters, pipeline layout, valves, connection methods and other geometric information parameters through the API of the ship design software; supplements or deletes the acquired geometric information, and uniformly converts the data format into a processable format; based on machine learning and pre-set rules, extracts qualified data from the pipe and outfitting data, extracts data of its specific type of pipe fittings, and then analyzes these data to further optimize the extraction rules; the extracted data is stored in the database of the data management module according to the structure and classification method.

[0007] The parametric modeling module retrieves the geometric information parameters of the ship's pipe and outfitting unit module equipment extracted in advance, and generates a component model script using modeling logic and rules, wherein the structure of the hull can be divided into many individual components, and a specific component model is generated by parsing the JVI function of the modeling software; after the model is generated by parameters, the components are placed in corresponding positions and assembled into a new model.

[0008] The visualization display module is based on the data extraction and parametric modeling module; by calling the database ship pipe and outfitting model and parametric data file, clicking on a specific part in the model, a comprehensive and intuitive three-dimensional display of the ship pipe and outfitting structure and layout is made; and detailed information of the part is obtained.

[0009] The data management module stores all data in the process of ship pipe and outfit parametric design, and stores the data in categories. It manages and modifies batches of ship pipe and outfit data in a unified manner, and the modified data is automatically updated to the database, and the relevant ship pipe and outfit models are updated synchronously.

Component parameters include pipeline parameters, equipment parameters, etc. Common parameters are parameters that can be used in common by components, such as feature elbows, tees, straight pipes, etc., and make them into parametric data spreadsheet templates.

[0011] Based on machine learning and pre-set rules, qualified data is extracted from pipe and outfitting data. For example, rules are set to extract data of specific types of pipe fittings, such as elbows, tees, straight pipes, etc., to extract data of specific types of pipe fittings, and then analyze these data to further optimize the extraction rules and improve the accuracy and efficiency of data extraction.

When the parameters of a single component change, only the geometric parameters of the component itself change, such as pipe diameter, pipe length, elbow angle, branch angle and other geometric dimensions; when the shared parameters change, all components using the shared parameters will change accordingly. After the parameters generate the model, the components are placed in the corresponding positions and assembled into a new model, such as the connection method between pipes and pipe fittings, the installation position of brackets and pipes, etc., to generate a parametric model of the piping system.

Based on the data extraction and parametric modeling modules, the visualization display module comprehensively and intuitively displays the ship's piping and outfitting structure and layout in three dimensions in the form of animation according to the database ship piping and outfitting model and parametric data, and clearly presents the connection method of each component.

[0018] The visualization display has an interactive operation interface, which can be used to set parameters, edit models, and optimize controls through menus and toolbars. Parameter setting is done by inputting parameters and variables. Under the intuitive 3D model display, the geometry of the model is recalculated according to the parameters, and different types and specifications of ship pipe component models can be quickly adjusted and generated.

It provides fast data query and retrieval functions, adopts data storage methods and index design, and performs data retrieval based on conditions such as pipe fitting names, parameter values, connection relationships, etc. The query results are displayed in the form of tables, charts, etc.
