Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] The invention is a data display method in the distribution network strictly following the function specification of the distribution network automation system. The technical scheme of the invention is mainly aimed at the method for displaying data of real-time database and relational database in the distribution network automation system.

[0040] Most manufacturers display standard SVG images on the page, but they also use custom-format image display, because they can customize image formats that are more in line with business characteristics according to unique business characteristics and editing tools. For example, the vector diagram in the format of lpf (proprietary format for describing two-dimensional vector graphics) is a vector diagram in its own format, which is generated by a specially customized configuration tool, which is mainly written i...

Abstract

The invention discloses a data display method in a power distribution network automated system. The method includes the steps that an SVG standard vector diagram is converted into a C# object; a CIM file, namely a common information model file, is analyzed and mapped to elements of a lpf vector diagram; the lpf vector diagram obtains a measurement point topological relation from a relation database; a dynamic lpf is embedded into a JSP through an ActiveX control, and a configuration graph is displayed in a WEB page. The data display method solves the real-time display problem of data in a real-time database and data in the relation database in power distribution network automated system environment; on the premise that an existing power distribution network system is not changed, common information model analysis is finished, the SVG vector diagram is converted into a lpf diagram with an owned format, the information is displayed in the lpf diagram, and then javascript and the ActiveX control are embedded into the lpf diagram, so that the data in the real-time database and the data in the relation database are displayed in real time on the JSP.

Description

technical field [0001] The invention belongs to the technical field of distribution network automation systems, in particular to a data display method in the distribution network automation system. Background technique [0002] Scalable Vector Graphics (ScalableVectorGraphics, SVG) is based on Extensible Markup Language (XML), a graphic format used to describe two-dimensional vector graphics. SVG is developed by W3C and is an open standard. [0003] Document Object Model (DocumentObjectModel, referred to as DOM), is a standard programming interface recommended by the W3C organization for processing Extensible Markup Language. [0004] ActiveX is Microsoft's name for a series of strategic object-oriented programming technologies and tools, the main technology of which is Component Object Model (COM). In networks with directory and other support, COM becomes Distributed COM (DCOM). When creating a program that includes ActiveX, the main job is the component, a program that ...
