Method for automatically drawing DCS picture into real-time database picture

Abstract

The invention discloses a method for automatically drawing a DCS (Distributed Control System) picture into a real-time database picture, which specifically comprises the following steps of: reading the DCS picture of a DCS manufacturer, and analyzing a file to obtain all nodes; the method comprises the following steps: formulating necessary information templates for drawing various objects according to a real-time database picture object drawing method, and extracting useful information from all nodes read by a DCS (Distributed Control System) according to required information in the templates; uniformly converting the information of different manufacturers into the format of the real-time database by taking the information required for drawing the real-time database flow chart as a standard; a real-time database program interface is provided by a manufacturer, software for writing and drawing a flow chart is utilized, a required object is added into a corresponding picture, and a real-time database picture is finally generated, so that the method has the advantages that the DCS picture is automatically drawn into the real-time database picture under the condition that the DCS picture exists, the human resource consumption during the construction of a real-time database is reduced, and the real-time database picture is automatically drawn. And the accuracy and the consistency of the real-time database picture and the DCS picture are improved.

Description

technical field [0001] The invention relates to a method for drawing a DCS picture into a database picture in the petrochemical industry, in particular to a method for automatically drawing a DCS picture into a real-time database picture. Background technique [0002] In the construction of new devices in the petrochemical industry, a DCS (distributed control system) system is generally built first, and then a real-time database is built to save historical data and remotely monitor the operation of the device. The data display of the real-time database also requires a graphical interface. In order to monitor the consistency, the traditional method is to draw the real-time database screen by artificially combining lines, characters, data, rectangles, circles, polygons and other objects according to the DCS screen. [0003] When there is already a DCS screen, the real-time database screen is drawn manually. The work is repeated, human resources are wasted, and the screen deli...

AI Technical Summary

Problems solved by technology

[0003] If there is already a DCS screen, draw the real-time database screen manually, which will lead to duplication of work, waste of human resources, and long delivery time for the screen. Incorrect display and other problems, a large amount of rework

Human resources are relatively scarce during the construction of the device, but the lag in the construction of the real-time database will lead to incomplete data records at the initial stage of the device's start-up, and the loss of valuable original start-up data
