Traditional GIS systems are two-dimensional, intelligently expressing plane geographic information, low in visualization capabilities, and unable to cope with high display requirements, so a three-dimensional GIS system was introduced. At present, the 3D GIS system has been gradually used in display platforms such as smart grids. For example, the Chinese patent with the publication number CN 102509330 B proposes an application of a virtual 3D system for substations based on power GIS, including panoramic data generation, panoramic configuration, and panoramic Display and panorama interaction, generate all the data required by the power GIS-based substation virtual 3D system through two steps of panorama generation and panorama configuration, and then perform 3D rendering on the generated data through 3D display technology on the user browser side, so as to realize Real-time display, roaming and zooming of the 3D scene; also query the historical data of the equipment through user interaction, and communicate with the power GIS system and MIS system to complete data analysis; users can also perform virtual operations on the equipment and monitor the real-time status of the equipment Preview of switching and operation process.

The above solution has panoramic display and interactive functions. However, its display is only a three-dimensional display without combining multimedia display technology, and cannot highlight the dynamic situation of the device. The existing dynamic display is usually realized by using flash animation. However, in the prior art, flash loading and map switching are generally stuck, causing the screen to appear blank for about one second, which greatly affects the user experience. Some application scenarios that require high precision, such as power grids, are also very easy to cause safety accidents.

Play the flash file in the loaded configuration file.

The following is a specific example to illustrate the above three-dimensional macro display method:

S1. Formulate 3D model production technology and database building standards and specifications according to the display requirements, and at the same time collect, check, check, and confirm 3D basic geographic data, 3D grid data, 3D model data, and information on the results of smart grid application demonstration areas.

S2. Process the relevant data acquired through various channels into the database, create a 3D display database, group and classify management according to the actual application scenarios of the 3D model, and facilitate the application; carry out the provided terrain DEM data and digital orthophoto maps organizational management.

S3. Integrate terrain image data with multiple resolutions, and use terrain image publishing tools to publish terrain image scenes. Integrate terrain image scenes, vectors, thematic maps, and three-dimensional power data, render according to relevant national standards, color, line thickness, font and display lines, substations, equipment voltage level colors, equipment symbols, etc., generate and publish three-dimensional GIS map scenes .

S4. According to the display effect, screen and classify the collected picture materials, and rename all the pictures. The picture materials include various equipment and lines in the power grid; the naming method is based on the same serial number of the same scene, for example: base map 1. Cutout 1-1, circuit diagram 1-1-1. Store pictures of the same scene in the same folder to facilitate centralized import of pictures. In order to enhance the display effect, image processing software can be used to preprocess the image, including preliminary adjustment of image brightness, saturation, contrast, and clarity. If it is necessary to focus on displaying details in the scene, operations such as cutout and edge blurring are required; if there is equipment and scene superimposed display, the picture can be cropped and superimposed. All the processed pictures, including various elements that need to be displayed in the extracted 3D display components, such as UHV equipment, low voltage equipment, pipeline data pictures, etc., are output through the 3D display components into high-precision pictures with a resolution of 1920*1080 , to generate the final flash display basic material.

S5. Planning and designing the overall flash scene. The design of the overall style includes creativity, color, tone, color, rhythm, page layout of the main screen, etc., and the overall visual experience or visual impact formed. Preliminary expectations on which parts the whole animation includes and which components each part includes.

For example: According to the expected display effect, the overall display effect is planned to be composed of 3-4 display scenes, and each display scene is created and generated by a stage. The stage size is unified to 1920*1080 pixels.

S6. Make flash scene 1, import all the material pictures needed by scene 1 into the library, and import sound into files in two formats, "*.wav" and "*.mp3", and make all flash scenes in this way; The flash scene corresponds to the above flash playback file.

S7. Perform flash playback settings by setting the time axis. The time axis is a window that uses layers and frames to organize and control animation content when creating animation. The content in layers and frames changes with time, thus generating animation. The timeline mainly consists of layers, frames and playheads. In the time axis area, multiple layers can be created as needed. Generally, pictures of the same category are created in the same layer, which is convenient for editing at the same time when selecting, and the layers can be named according to the content of the picture, such as the substation layer, feeder layer, etc. When editing the substation layer, you can import the substation material from the library to the stage, and place the material in an appropriate position according to the base map. If you need to add radiation effects and line display, you need to use tools such as brushes and fills in the toolbar. Effect added. Among them, in the drawing of the line display, it is necessary to replace the base map with a line map containing data display, and then draw the shape bit by bit according to the line instructions. After the drawing is completed, replace the base map with the original picture without lines, and then click on the line map Layer display, the lines can be clearly displayed on the stage. For the drawn line layer, you can also adjust the color effects of its attributes, such as transparency, chroma, brightness, etc. For various image materials imported on the stage, they can be set as components, and the material of component properties can be used for more animation editing. The basic animation effects include shape tweening and traditional tweening, both of which can realize the dynamic change effect of objects. The dynamic presentation of the 3D effect can not only be realized through the animation production of the time axis, but also can be enriched with more animation display effects through AS3.0. If the action code Stage.scaleMode=StageScaleMode.SHOW_ALL is added to the first frame of the timeline, the full-screen display of the animation can be realized; if stop() is added to the last frame, the animation can be stopped.

S8. Generate a configuration file including map coordinates, flash scenes and flash playback settings, and manage the configuration file, corresponding equipment (or other facilities that need to be displayed) and the operation identification corresponding to the equipment; clicking on the operation identification can trigger Locate the map scene where the device is located;

S9. When the operation instruction for the identification is obtained, trigger loading of the configuration file, superimpose the flash scene in the configuration file on the position corresponding to the coordinates in the configuration file, and at the same time locate the map to the scene where the corresponding device is located according to the operation instruction ;Play the flash file after the positioning is completed to realize the animation display.
