Attribute definition method for monitoring picture graphic element

Abstract

The invention provide an attribute definition method for a monitoring picture graphic element. The method comprises the steps of predefining labeling modes of script command character strings of graphic element attribute variables in source codes; drawing the graphic element; defining corresponding displaying and operation script commands for each basic graph in the graphic element, and labeling the character strings representing the graphic element attribute variables according to the predefined labeling modes; defining a class and an index name for the entirety of the character string labeled graphic element, and adding the graphic element to a pre-established macro definition picture library; and citing the graphic element through the index name when the graphic element needs to be cited by a monitoring picture in a later period, and modifying the labeled variables in the character strings of the displaying and operation script commands, thereby finishing practical definition of graphic element attributes. When the graphic element is cited in the later period, the graphic element attributes can be modified only by citing the graphic element through the index and modifying the variables of the character strings, so the development efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a method for defining the attributes of pixels in a monitoring screen during the monitoring of equipment by a monitoring system. Background technique [0002] In the context of Industry 4.0, automation and information technology are becoming more and more mature, and my country's decentralized control system application market is growing moderately. Some problems were found in the long-term development and application. The screen development of the control system project needs to design and use the flow chart of the project engineering, a large number of physical schematic diagrams, and dynamic diagrams during project operation. Many pixels are reused, but the attribute definition part of each pixel is different. Each pixel needs to re-establish a data link with the database data, and re-define the attributes completely. When the project is relatively large, the search for labe...
