Description

Technical Field

[0001] The present application relates to the field of computer-aided design technology, and in particular to a method, system, storage medium, and device for modular reuse of pipeline three-dimensional models. Background Art

[0002] With the advancement of design methods and concepts, modular design is becoming a growing trend in large-scale piping design. While modular piping has made significant progress, 3D modeling has not seen significant advancements. While existing 3D design software offers parametric modeling capabilities, the increasing number of components within a unit makes parametric modeling and layout difficult. Consequently, current 3D piping design still relies on the traditional part-by-part layout approach. Specifically, designers must select and place each component within a unit one by one. This approach presents several challenges: First, modeling efficiency is low. When there are multiple similar modular units, designers must repeat the modeling process multiple times. This means that pipeline variables cannot be interchanged after modeling, making it impossible to reuse a single design for different design scenarios. Second, there is a lack of design constraints. For the same design scenario, different designers can produce widely varying results, resulting in inconsistent layouts and varying component models.

[0003] Therefore, to address the above problems, it is urgent to propose a new modular method for pipeline three-dimensional models. Summary of the Invention

[0026] The pipeline configuration is parsed to obtain the relative position relationship of the components, and specific components are placed one by one according to the relative position relationship to complete the placement of all components in the pipeline and realize modular reuse of the pipeline three-dimensional model.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0047] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0048] The present invention provides a modular reuse method for pipeline three-dimensional models. Figure 1 Flowchart of a modular reuse method of a pipeline 3D model according to an embodiment of the present application. Figure 1 , the method includes the following contents:

[0049] According to the spatial position of the pipeline model to be modularized, a parameterized skeleton model of the pipeline is created, the interface 400 between the skeleton model and the external design environment is defined, and a marking element 500 is set in the skeleton model. In this step, the interface 400 between the skeleton model and the external design environment is the input element required for the subsequent instantiation of the skeleton model, which is used for the dynamic generation of the skeleton instance model. The skeleton model interacts with the external design environment through the interface 400, and the skeleton model receives the external environment input and generates output. When the external design environment changes, the output of the skeleton model also changes accordingly. Based on this dynamic interaction process, the dynamic adjustment of the skeleton model based on the design environment is realized.

[0050] Analyze the relative positions of the components in the pipeline model and divide the components in the pipeline model into active components and passive components. In this step, the spatial position of the active component depends on the skeleton model, and the spatial position of the passive component depends on the active component. For a specific example, see Figure 2 The left flange 100, gasket 300, and right flange 200 are sequentially connected to form a fixed assembly, and the relative positions of the components within the assembly remain unchanged. The left flange 100 is the active component, and its spatial position is determined by reference to the marking elements of the external design environment. The gasket 300 and right flange 200 are passive components, and their spatial positions are determined by reference to the left flange 100.

[0051] Construct a pipeline configuration, which includes pipeline variables, the relative position relationship between the active component and the marking element 500, and the relative position relationship between the passive component and the active component. Assign values to the pipeline configuration, and group the pipeline configuration assignments into an assignment set. In this step, an XML-formatted configuration file is constructed to record the constraint position relationship of the components and the pipeline variables. Pipeline variables include component specifications, etc. It should be noted that the specific specifications of the components do not need to be specified in the configuration file. Preset symbols can be used for marking, thereby completing the declaration and release of variables. For example, the specifications of the pipeline component "flange" are not directly specified, but the variable name "flange specification-connection equipment" is used for variable declaration.

[0052] Next, based on the actual design scenario, specify specific values for the piping configuration. For example, the specific value for a piping component might be "slip-on flange - pipe outer diameter." The collection of assigned values is called an assignment set, and multiple assignment sets can be created based on application requirements. The specific steps include: first defining an assignment set object. The elements within an assignment set are assigned variables, which consist of a variable name and a value; then adding the assigned variables to the assignment set; and finally, creating multiple assignment sets based on specific application requirements.

[0053] The skeleton model, pipeline configuration, and assignment set are combined into a pipeline module. In this step, the name of the skeleton model and its directory are recorded in the above-mentioned XML configuration file, and the assignment set is saved to the XML configuration file. The configuration file is encapsulated into a complete management module, which serves as a management modular reuse template.

[0054] Configure the pipeline module into the 3D software. When modeling in 3D, select the pipeline module. Figure 3 Select the "Central Cooler Unit" piping module. The right window displays the prototype of the central cooler 3D model. Select "Scheme 1," which specifies the specifications for the standard series components. First, instantiate the skeleton model, then parse the assignment set and piping configuration to complete the modular reuse of the 3D piping model.

[0055] During the above implementation process, any group of pipeline models can be packaged into a reusable pipeline module, which has the advantage of one-time customization and multiple uses. The entire pipeline model modular reuse process is designed based on actual design scenarios, which can significantly reduce repetitive operations to improve modeling efficiency, and can effectively establish design constraints to improve design quality. Furthermore, the method of the present application also promotes the modular design of pipelines in three-dimensional models. A pipeline model can be applied to a variety of design scenarios, and has the function of rapid layout of pipeline models with the same shape, such as sounding pipe modules. In addition, for complex equipment unit models, the consistency and accuracy of the design can be maintained based on the same reuse model, such as central cooler equipment units.

[0056] In one embodiment, the marking elements within the skeleton model further include numbering the marking elements 500 one by one. The numbering is a combination of a number and a brief description. The marking elements include at least one of the following: a point, a line, a plane, and a coordinate axis. Specifically, the coordinate axis marking elements are numbered as "Axis" + a number, and the number cannot be repeated; the point marking elements are numbered as "Point" + a number, and the number cannot be repeated.

[0057] In one embodiment, creating a piping configuration includes:

[0058] Create an XML configuration file,

[0059] In the XML configuration file, component specifications are marked with preset symbols, and the number of the marking element 500 corresponding to the active component in the skeleton model is recorded. The number of the connection point between the passive component and the active component is recorded.

[0060] For active components, their instantiation positions depend on the skeleton model, and the number of the expected corresponding tag element 500 in the skeleton model is recorded in the configuration file. Specifically, when describing the position constraint information of the component "flange", the "port1" connection point of the "flange" coincides with the tag element "Axis_002" of the skeleton model. The position constraint types of active components and tag elements include the component coordinate axis coincident with the spatial coordinate system of its parent node, the paired coordinate axes coincident, the paired coordinate axis origin coincident, the X-axis directions are opposite, the Y-axis directions are opposite, the Z-axis directions coincide, and the paired coordinate axis origin has an offset distance, the X-axis is coaxial (the directions can be the same or opposite), and the Y-axis direction has a relative rotation angle.

[0061] For slave components, whose instantiation locations depend on the master component, the master component and its corresponding connection point numbers are recorded in the configuration file. For example, if the "port1" connection point of slave component 1 is connected to the "port2" connection point of master component 2, the master component 2 and its connection point "port2" can be recorded.

[0062] In one embodiment, assigning a value to the pipeline configuration includes assigning a value to the pipeline configuration by combining a variable name and a variable value.

[0063] In one embodiment, instantiating a skeletal model includes:

[0064] Place the skeleton model in an external design environment,

[0065] Select specific external elements in the external design environment and use them as input elements of the interface 400 of the skeleton model, that is, use the external elements to replace the interfaces in the skeleton model one by one. Figure 4In this context, external elements refer to the central chiller equipment in the design environment.

[0066] Update the skeleton model, and the marking elements 500 in the skeleton model are dynamically adjusted accordingly. Figure 6 In the figure, when the interface 400 in the skeleton model changes, based on the distance L between the two interfaces 400, the marking element 500 is located in the middle of the interface 400, and the distance from the single interface 400 is L / 2. Therefore, when the position of the interface 400 changes, the position of the marking element 500 is dynamically adjusted accordingly.

[0067] In one embodiment, parsing the assignment set and pipeline configuration to achieve modular reuse of the pipeline three-dimensional model includes:

[0068] Process the configuration information, read the assignment set, and obtain the specific specification information of the component,

[0069] Using the specific specification information, search the pipeline component library and obtain the specific components from the pipeline component library.

[0070] Then analyze the pipeline configuration, obtain the relative position relationship of the components, and place the specific components one by one according to the relative position relationship. The principle of placing components one by one is: give priority to placing the reference components when arranging the components. The placement position of the active component refers to the marking element, and the placement position of the passive component refers to the active component. After all components are placed, delete the skeleton model from the external design environment. Figure 4 To complete the placement of all components in the pipeline and realize the modular reuse of the pipeline 3D model. Figure 4 and Figure 5 This is the reuse result of the same pipeline module based on different external design scenarios. It can be seen that this method can realize the modular reuse of pipelines based on different design environments.

Furthermore, the present invention may take the form of a computer program product implemented on a computer-readable storage medium (including but not limited to a magnetic disk, CD-ROM, or optical storage) containing computer-usable program code.
