Description

Technical Field

[0001] This invention relates to the field of computer-aided design technology, specifically to a closed-loop verification method and system that integrates pipeline models and structural models. Background Technology

[0002] The design process for large-scale industrial projects such as thermal power plants typically involves multiple disciplines, including process piping, building structure, electrical systems, and HVAC. Each discipline generally uses different design software, resulting in "data silos." The typical workflow is as follows: (1) The pipeline professionals use 3D software such as AVEVAPDMS to complete pipeline modeling and use professional software such as CAESARII to perform pipeline stress analysis and generate a calculation report containing load information of each node of the pipeline.

[0003] (2) The building structure professionals use BIM software such as Autodesk Revit to perform 3D modeling of the factory building and structure, and use software such as PKPM to perform structural calculations.

[0004] (3) The information on supports, embedded parts and holes is usually provided in two dimensions. Structural engineers need to consult the CAESARII mechanical calculation report and read the coordinates of the load points, the forces (Fx, Fy, Fz) and the moments (Mx, My, Mz) data.

[0005] (4) Based on the stress data, the structural engineer manually arranges the embedded parts, supports, and hangers on the structural plan drawing created by 2D software such as AutoCAD, and reserves the holes. This process is extremely tedious, time-consuming, and labor-intensive, and is very prone to data transcription errors or omissions due to human negligence.

[0006] (5) In the later stages of the design process, the 3D models of various disciplines (such as the pipe model in PDMS and the structural model in Revit) are imported into model review software such as Autodesk Navisworks for collision checks. Since the early design and data submission are mainly based on 2D drawings and manual judgment, a large number of spatial collision problems will inevitably occur, such as collisions between pipes and structural beams and slabs, discrepancies between the location of embedded parts and the actual support points of pipes, insufficient space for the installation of supports and hangers, and interference between embedded parts and structural steel bars.

[0007] (6) The process for resolving collision issues is inefficient. After reviewers discover a collision in Navisworks, they need to take a screenshot, mark it, and notify the relevant designers. Designers need to switch between Navisworks and their own design software repeatedly to find the problem, make corrections, and then re-export the model for verification. The whole process is time-consuming, costly in terms of communication, and prone to introducing new errors. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to provide a closed-loop verification method and system that integrates pipeline model and structural model, so as to realize the automated verification of model defects.

[0009] The technical solution adopted by this invention to solve its technical problem is a closed-loop verification method that integrates pipeline models and structural models, including the following steps: S1: Automated parsing and integration of heterogeneous data. The pipeline model file is input into the pipeline stress analysis software to analyze the load point information, resulting in a pipeline stress analysis file.

The error location file records the unique identifier of the conflicting component, the three-dimensional coordinates of the collision point, the recommended viewing point information, and the problem description. S5: Closed-loop and iterative design modification. Load the error location file in each native design software through the corresponding plugin, automatically locate and highlight conflicting components, adjust the view according to the recommended observation viewpoint information, and after completing the modification, re-export the model and repeat steps S1-S3 for iterative review until all problems are resolved.

[0015] Furthermore, in S5, the supporting plugin automatically performs view navigation, component highlighting, and information prompting operations in the native design software.

The preset component model generation module is used to project load points onto the installation plane of structural components in a two-dimensional computer-aided design environment, generate preset component models, and associate the mechanical data of load points in the properties of the preset component models. The model fusion and verification module is used to export the preset component models and pipeline models into a unified data format, and perform collision checks and specification compliance checks in the model review platform. The review report generation module is used to automatically generate a comprehensive review report and error location file, recording the unique identifier, coordinates, viewpoint information and problem description of the conflicting components; The closed-loop feedback and iteration module is used to load error location files in various native design software through supporting plugins, automatically locate and highlight conflicting components, and support re-triggering the review process after design modifications.
