Method for drawing an electrical wiring diagram of WEB front end

Abstract

A method for drawing an electrical wiring diagram at a WEB front end includes editing drawings, dragging and dropping primitives, typesetting pictures, and configuring attributes of pictures and primitives; defining a structure type according to power parameters of equipment and circuits and adding the structure type into a structure definition list; in the template screen, using the structure type to edit the template variables and assign the member variables under the template variables; using the structure type to define the structure variables, and adding the variables into a structure variable list; for the template primitives, using the variables of the structure to replace the template variables, and thus realizing the variable binding of the batch real-time library; for non-template primitives, using real-time library variables to realize binding one by one; constructing an SVG file, using a program language conversion method to convert the current screen program logic and datainto a SVG file for archiving which is loaded and used by a WEB page to achieve graphics rendering. The invention supports the visual design mode, can effectively improve the development efficiency,can save the development cost, and can realize the good graphics drawing requirement.

Description

technical field [0001] The invention relates to the technical field of graphics drawing, in particular to a method for drawing an electrical wiring diagram by a WEB front end. Background technique [0002] The application of WEB technology in the remote monitoring of power equipment enables many previous tasks to be realized through a WEB browser, which not only simplifies daily work, but also expands the management scope of the power dispatching automation system, while greatly reducing software upgrade and maintenance costs. The power system is represented by analog graphics and the graphical display of power data is an important content of the output display of the power monitoring system. According to the relevant electrical technical standards promulgated by the state, the engineering drawings that use electrical wiring graphic symbols and text symbols to represent the components in the electrical installation and their interrelationships are called electrical wiring di...

Problems solved by technology

This method simplifies part of the work in drawing electrical circuit diagrams, but in the face of hundreds of thousands of label variables, using SVG development tools to bind them one by one is laborious and error-prone, and it is not easy to find mistakes

[0004] In the traditional WEB development of the power monitoring system, due to the complexity of the electrical circuit diagram, the workload of drawing the front-end electrical circuit diagram is huge, and once the electrical circuit is changed, the source program of the power monitoring system software must be modified, resulting in its development cycle. The maintenance work is also difficult in the later stage; the successfully developed power monitoring system software has a low reuse rate due to the difference of each monitoring item, making it very expensive

[0005] It can be seen that the method of drawing the WEB front-end electrical wiring diagram in the prior art has a long development cycle and a low reuse rate, resulting in high cost and low efficiency. Therefore, it is difficult to adapt to the fierce market competition environment.
