Simulation modeling method and device based on graph matching identification

Abstract

The invention discloses a simulation modeling method based on graph matching identification, comprising the steps: acquiring configuration information of a drawing in a source file of a first format, the configuration information comprising line segment information and text information; generating a redrawn picture and a mapping table according to the obtained configuration information, wherein the redrawn picture comprises picture libraries composed of line segments and connecting line segments between the picture libraries, and the mapping table comprises mapping relations between the text content and the line segments and position coordinates of the line segments; according to a preset feature information base, identifying the picture library category in the redrawing picture, the attribute of the connecting line segment and the parameter attribute in the mapping table; converting the recognized picture library category, the attribute of the connecting line segment and the parameter attribute into a simulation model file; and importing the simulation model file into simulation modeling software to generate an executable simulation model. Correspondingly, the invention further provides a simulation modeling device based on graph matching identification. According to the simulation modeling method, the modeling efficiency and the modeling accuracy can be improved.

Description

technical field [0001] The invention belongs to the technical field of nuclear power, and in particular relates to a simulation modeling method and device based on graphic matching recognition. Background technique [0002] The simulation model for the I&C design of a nuclear power plant should be able to accurately reproduce the logical control functions shown in the drawings of the finished I&C products of the nuclear power plant. At present, there is an automatic import modeling method based on XML (Extensible Markup Language) text files of configuration data. This method first converts the logical configuration information of the finished instrument and control drawings into XML text file, and then convert the XML file into a format text file that the simulation modeling software can recognize through computer analysis text information technology, and automatically import it into the simulation modeling software for direct editing and compiling to generate an executable ...

AI Technical Summary

Problems solved by technology

[0003] The premise of the automatic import modeling method based on XML files is that the drawings of I&C products must be able to be parsed into XML files containing complete configuration information. However, due to the lack of a very strict and effective drawing specification system in nuclear power plants, some departments The XML file of the finished instrument and control drawings cannot be provided, or the provided XML file does not contain complete configuration data. Therefore, automatic import modeling cannot be fully realized, and manual modeling is still required, resulting in low modeling efficiency and low modeling accuracy The problem
