Description
Technical Field
The invention belongs to the technical field of data visualization, and particularly relates to a method for visualizing a tidal current diagram of a power grid.
Background
The steady distribution of voltage and power in an electric power system is called tidal current, and a circuit graph formed by distributing the voltage and the power of an electric network through electrical signs such as lines, nodes, reactance elements and the like is an electric network tidal current graph. The power grid tidal current graph occupies an important position in the operation of the power grid.
In a large-screen data visualization scheme in the power industry, a power grid tidal current diagram needs to be visually displayed. Customers in the power industry have higher requirements on the display performance of the tidal current diagram of the power grid, so that the display smoothness on large-resolution large-screen equipment is guaranteed, and the requirement on the timeliness of refreshing the visualized service data is also met.
In the current common large-screen data visualization scheme, a WPF graphical interface framework is adopted as a development technology for visualization presentation at a large-screen end. The WPF graphical interface framework is used as a desktop software graphical interface development framework and has the characteristics of short development period and quick start of software developers. However, in order to facilitate rapid development by developers of various levels, there are higher abstraction structures and interface packages. It is determined that the operation performance of the method is obviously lower than that of the bottom development technologies such as Direct3D, Direct2D and the like.
As shown in fig. 1, which is a schematic diagram of a WPF graphics development framework, a PresentationCore and a presentationopennetwork in an upper layer constitute an abstract structure of the WPF graphics interface framework. The system is constructed on a Windows kernel and a User32 technical system, and simultaneously supports the DirectX (including sub-parts such as Direct3D, Direct2D and the like) hardware accelerated rendering technology. The WPF graphics development framework has a higher level of abstraction than the Windows graphics framework shown in FIG. 2.
The WPF graphic development framework also supports hardware accelerated rendering, and the realization principle is as follows: referring to FIG. 1, the WPF graphic development framework is mediated by the milcore module with DirectX. The milcore module is responsible for rendering and displaying the WPF graphical interface framework, translates the rendering and displaying of the WPF into specific rendering instructions and delivers the rendering instructions to DirectX for rendering. However, when an application program developed by the WPF graphics development framework performs rendering, the rendering efficiency of the milcore module is low due to the abstract structure and the encapsulation of the application program. As shown in fig. 3, a WPF graphical interface framework rendering schematic diagram shows a group of processes for rendering a black border circle by a graphical development framework, where in fig. 3, a total of 4 rendering instructions are required to complete the rendering of the black border circle.
In the existing large-screen visualization scheme, one power grid tidal current graph usually comprises hundreds of various graphic elements such as circles and ellipses, and therefore when the power grid tidal current graph is rendered and displayed by adopting the original rendering technology of the WPF graphical interface framework, due to the slow rendering speed, the phenomenon that the power grid tidal current graph is not smoothly displayed on large-screen equipment and is easily blocked can occur.

The invention provides a power grid tidal current diagram visualization method, which mainly comprises the following steps: creating a visual UI component Element2D for realizing the visualization of the tidal current picture Element to obtain a tidal current diagram Element graph according to the tidal current diagram data structure of the power grid; creating a rendering context component Scene2D for generating rendering parameters according to the tidal flow graph element graphics; creating a rendering instruction generation component Core2D for interpreting rendering parameters as Direct2D rendering instructions;
the visualization UI component Element2D, the rendering context component Scene2D and the rendering instruction generation component Core2D are respectively encapsulated in different layers of the WPF graphical interface framework;
and Direct2D is not encapsulated in the WPF graphical interface framework, is independent of the WPF graphical interface framework and only performs message interaction with the WPF graphical interface framework.
Therefore, when the data file of the power grid tidal current diagram is not changed, in order to realize the real-time display of the tidal current diagram picture, the circularly executed rendering process comprises the following steps:
the visualization UI component Element2D, the rendering context component Scene2D and the rendering instruction generating component Core2D do not need to be created again, and the rendering instruction generating component Core2D saves the rendering instruction obtained last time; then, when a rendering cycle is performed each time, the rendering instruction generating component Core2D directly sends the rendering instruction stored for the previous time to Direct2D, the Direct2D executes the rendering process, and the rendering content is output to the D3 Direct component; displaying the rendering content to a universal view frame presentationframe by the D3Dimage component, and finishing the display of the rendering picture;
and if the data file of the power grid tidal current graph changes, the executed rendering process is as follows:
only aiming at the changed power grid tidal flow graph data file, creating a visualization UI component Element2D, a rendering context component Scene2D and a rendering instruction generation component Core2D, so that the rendering instruction which is changed is generated by a rendering instruction generation component Core 2D; meanwhile, the rendering instruction generation component Core2D stores the rendering instruction which is not changed, then the rendering instruction generation component Core2D sends the changed rendering instruction and the unchanged rendering instruction to Direct2D together, the Direct2D executes the rendering process, and the rendering content is output to the D3 Direct component; and the D3Dimage component displays the rendering content to the universal view frame presentationframe, and completes the display of the rendering picture. Therefore, when the data file of the power grid tidal current graph is changed, the method does not need to completely re-execute the rendering process for one time, and only needs to be executed in a targeted manner, so that the rendering efficiency is improved; for the condition that the data file of the power grid tidal current graph is not changed, the rendering instruction generating component Core2D only needs to directly send the rendering instruction to Direct2D, and the rendering efficiency is more efficient.
For Direct2D, due to its good architecture design and excellent rendering algorithm, the rendering algorithm implemented by the native kernel of the WPF graphical interface framework is greatly improved. Specifically, the rendering instruction sent directly to Direct2D by the rendering instruction generation component Core2D is a plurality of rendering instructions, that is: one tidal flow graph element corresponds to one rendering instruction; for Direct2D, multiple rendering instructions can be quickly assembled into one rendering instruction, so that in the subsequent steps, the rendering process can be completed only by executing one rendering instruction, and the rendering efficiency is remarkably improved.
The WPF graphical interface framework provided by the invention is combined with the Direct2D module, and the rendering performance of the original WPF graphical interface framework in the prior art is tested, wherein the table 1 is a rendering result table of the invention; table 2 is a prior art rendering results table:
TABLE 1
| Resolution of pictures | Number of figures | Refresh mechanism | Rendering frame rate | Fluency of picture |
| 7680x2160 | 500 | At intervals of 0.3 second | Over 30 frames | Is very smooth |
| 7680x2160 | 1000 | At intervals of 0.3 second | About 25 frames | Is very smooth |
| 7680x3240 | 600 | At intervals of 0.3 second | 22 frames(left and right) | Is smoother |
TABLE 2
| Resolution of pictures | Number of figures | Refresh mechanism | Rendering frame rate | Fluency of picture |
| 7680x2160 | 500 | At intervals of 3 seconds | 11 frames or so | Refresh delay 3 seconds |
| 7680x2160 | 1000 | At intervals of 3 seconds | About 8 frames | Refresh delay 5 seconds |
| 7680x3240 | 600 | At intervals of 3 seconds | About 5 frames | Refresh delay 3 seconds |
Comparing table 1 and table 2, it can be seen that, compared with the native WPF graphical interface framework in the prior art, the method of the invention effectively improves the picture rendering performance of the power grid visualization tidal current graph.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and improvements can be made without departing from the principle of the present invention, and such modifications and improvements should also be considered within the scope of the present invention.

then, the Direct2D calls a DirectX graphical interface rendering interface to render the picture content according to the assembled rendering instruction, and the rendered content is output to a D3Dimage component after the DirectX completes the picture rendering;
6.7, displaying the rendered content to a universal view frame presentationframe ork by the D3Dimage component, and finishing the display of the rendered picture;
step 7, judging whether the power grid tidal current diagram picture needs to be continuously displayed; if the power grid tidal current graph picture is closed, skipping to the step 9, and finishing rendering; if the power grid tidal current diagram picture is kept in an open state, executing the step 8;
step 8, returning to the step 2, judging whether the newly loaded power grid tidal current graph data file changes or not by the WPF graphical interface framework, if not, jumping to the step 6.5, sending the rendering instruction stored for the previous time to Direct2D by the rendering instruction generating component, and then executing the step 6.6-the step 7 to finish rendering once; the circulation is continuously carried out;
if the change occurs, the WPF graphical interface framework only loads the relevant power grid tidal current graph data files related to the change; then, through the steps 3-6.4, a rendering instruction which changes at this time is obtained; then, in step 6.5, the rendering instruction generating component sends the changed rendering instruction and the unchanged rendering instruction to Direct2D, and then executes steps 6.6 to 7 to complete the image rendering of the change and update of the primary power grid tidal current graph; the circulation is continuously carried out;
and 9, finishing rendering.
2. The method according to claim 1, wherein in step 4, the description information of the attributes of the power grid equipment includes name description information of the power grid equipment, relative position description information of the power grid equipment, and real-time load description information of the power grid equipment.
