Method of Automatic Matching and Verification of System Diagram and 3D Model in Pipeline Design

Abstract

The present invention relates to a method for automatically checking and matching a system chart and a three-dimensional model in a pipeline design. The method comprises: A. obtaining a PID chart and a three-dimensional model chart; B. generating a corresponding PID topology and a three-dimensional topology; C. searching the two topologies by respectively taking a same device as the starting point so as to generate a respective node sequence, taking the searched three links / three-way valves in to a separate queue, after the node sequence is searched, respectively taking the searched three links / three-way valves as the starting point to start to search and establishing a new node sequence, and respectively forming two corresponding node sequence groups; D. comparing the two node sequence groups one by one, wherein if all the nodes are consistent, the match is successful, and otherwise, the match is failed; and E. after the match is failed, outputting failure information, and after the match is successful, updating the three-dimensional topology and generating a new three-dimensional model chart. According to the method provided by the present invention, automatic match, check and update can be carried out on the PID chart and the three-dimensional model, so that working efficiency is greatly improved, and comparison errors are significantly reduced.

Description

technical field [0001] The invention relates to the comparison and verification of different types of data in pipeline design of a thermal power plant, in particular to a method for automatic matching and verification of system diagrams and three-dimensional models in pipeline design. Background technique [0002] In thermal power plant pipeline design, system design (design PID diagram) and layout design (real pipeline design based on actual space information, pipeline stress, etc.) and three-dimensional collision check are required separately, usually the two are independent and indispensable of the two parts. At present, the commonly used software for 3D modeling is PDMS (Plant Design Management System, Plant Design Management System), which is a set of 3D plant design management system that can be applied in many fields. Prone to collision problems, improve design efficiency and quality. In system design, Siemens' COMOS power plant collaborative design platform is ofte...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the full manual design and matching, the error rate of the comparison between the two is very high, such as pipeline branches, connection relationships, equipment levels and other information are easily lost

[0005] 2. Low efficiency and huge workload. Due to the large amount of information in the pipeline, it is extremely difficult to check and update

[0006] 3. The data consistency is poor. The content is easily modified and lost after multiple manual transfers, which affects the consistency of the two data, which is not conducive to version control and multi-person and multi-professional collaboration

[0007] 4. Due to the cumbersome process, the workload of designers has been greatly increased, which has seriously affected the enthusiasm of designers to participate in digital design, and affected the overall promotion and application of 3D digital design
