Method for automatically drawing process flow diagram in DWG format in SPPID

Abstract

The invention discloses a method for automatically drawing a process flow diagram in a DWG format in SPPID, and the method comprises the steps: making a DWG format legend, building a mapping relation between the DWG format legend and an SPPID legend, taking a DWG legend library as a template, carrying out the information recognition of a DWG drawing, configuring a process flow diagram analysis rule, carrying out the analysis of the DWG drawing, and generating an intermediate file which can be used for the automatic drawing and reading of the SPPID. The SPPID drawing module reads the intermediate file for automatic drawing, and a drawing log is generated. The method is easy to operate, and the drawing efficiency and the drawing accuracy are improved.

Description

technical field [0001] The invention relates to the field of SPPID drawing, in particular to a method and system for automatically drawing a process flow chart in DWG format in SPPID. Background technique [0002] With the introduction of the concept of Industry 4.0 and the introduction of the national digital economy policy, the chemical, shipbuilding, electric power and other industries are more willing to carry out digital delivery and build smart factories, and the number of engineering projects requiring engineering companies to carry out digital delivery has also increased sharply. However, as one of the important software for digital delivery and integrated design, there are many obstacles to the promotion and application of the intelligent process flow chart drawing software SmartPlant P&ID (hereinafter referred to as SPPID). The prominent problem is the design method from the traditional DWG format process flow chart to SPPID During the transformation and upgrading ...

Problems solved by technology

However, as one of the important software for digital delivery and integrated design, there are many obstacles to the promotion and application of the intelligent process flow chart drawing software SmartPlant P&ID (hereinafter referred to as SPPID). The prominent problem is the design method from the traditional DWG format process flow chart to SPPID In the process of transformation and upgrading, designers need to flip DWG format drawings in SPPID software, which causes a lot of waste of human and financial resources and affects the progress of the project. At the same time, the quality of drawing is greatly affected by human experience factors, which seriously affects the progress of digital delivery projects.
