Method for automatically generating instrument arrangement diagram by utilizing PDMS data source

Abstract

The invention discloses a method for automatically generating an instrument arrangement diagram by utilizing a PDMS (Plant Design Management System) data source. The method comprises the following steps of obtaining instrument information from a PDMS model and dividing the obtained instrument information into two data sources of an instrument type except a valve and a valve type; accepting modification of corresponding information of the two data sources of the instrument type and the valve type by a user to form a final data source; and importing the final data source into an Autocad diagram which stores a PDMS two-dimensional arrangement diagram by adopting a ''two-section scattering type'' or ''one-section scattering type'' importing plug-in according to a preset threshold condition of an instrument point number in the arrangement diagram so as to automatically generate the instrument arrangement diagram.

Description

technical field [0001] The invention relates to the field of instruments, in particular to a method for automatically generating instrument layout diagrams using PDMS data sources. Background technique [0002] The production process of traditional instrument layout drawings has always been completed by traditional purely manual input and modification. The general design principle is to put the instruments on the pipeline layout drawing provided by the pipeline professional into the process equipment layout drawing, and then mark the instruments with serial numbers in order. The design idea is simple and easy to understand, but in the process of project execution, two common problems may arise: [0003] The first one: takes up a lot of graphics. That is, information such as the position number and elevation of each instrument is placed on the equipment layout drawing, and the drawing interface is rather confusing and does not have the characteristics of simplicity; [000...

AI Technical Summary

Problems solved by technology

[0005] The above two problems directly or indirectly affect the layout of the next instrument junction box JB, the selection of the instrument bit number entering the instrument junction box, the formulation of the instrument wiring table, and even the subsequent instrument air supply layout diagram, instrument heat tracing The design of the layout plan has a cascade of effects

While designing the instrument layout, the time for other instrument design work is decreasing, which will bring many negative effects to the engineering design.
