SVG (scalable vector graphics) is based on extensible markup language, a common grid single line diagram file format. At present, a method for analyzing and rendering a single line graph file in a power grid SVG format for mobile equipment and monitoring real-time operation data based on a wiring diagram mainly comprises the following steps:

The advantage of this approach is that the development effort is small, as long as the data format is defined and the data parsing is done, and it can be reused directly if web-based graphical presentation and data monitoring has been implemented. However, the method also has some problems that the analysis, the display, the data analysis and the like of the graph all depend on the browser, the overall performance is easily influenced by the browser, and the time is long when the graph is large; meanwhile, an interface for calling the JavaScript method through the native language has security holes and potential safety hazards; in addition, the displayed information only contains representation data, and the power grid topology information is lacked.

According to the method, on the basis of the method 1), data communication is carried out by using a system native development language, so that a communication interface is prevented from being exposed to a browser, meanwhile, analysis of real-time data is also completed by the native development language, and the dependence degree of the overall performance on a browser kernel is reduced to a certain degree.
