Description

Technical Field

[0001] The present invention relates to the field of smart grid GIS technology, and in particular to an application calling method and system based on a three-zone GIS integrated component of a power grid control system. Background Art

[0002] In the production control area 1 of the control system, the human-computer browsing mode based on the client / server (C / S) architecture is usually adopted. In the non-production control area 3, the human-computer interaction needs and business based on the browser / server (B / S) architecture are also developing rapidly. In the actual construction, the research and development of GIS components in the C / S editor and browser are carried out first. Under the design of common functional modules, based on the different technical routes of the C-end and B-end, the graphic GIS components are implemented based on the two technology stacks of Qt, QML and HTML5, JavaScript, respectively, which can meet the synchronous display of the first and third areas of the basic map screen. Due to the differences in the two technical routes, there are certain differences in the abstraction and interaction definition of layers and elements in the underlying GIS library in the specific implementation, and these differences need to be shielded in the component encapsulation. The more complex the map interaction operation and the richer the visualization effect, the greater the challenge to the final consistency effect and program maintenance. Summary of the invention

[0003] Purpose of the invention: The present invention provides an application calling method and system based on the one-three zone GIS integrated component of the power grid control system. Through a unified interface and event mechanism, a set of shared core GIS library codes is implemented to meet the one-three zone synchronization effect of map screen and interaction, thereby improving the efficiency of application research and development and saving manpower costs in project implementation.

[0004] Technical solution: The present invention discloses an application calling method based on a three-zone GIS integrated component of a power grid control system, comprising the following steps:

[0005] Step 1: Data resource preparation: deploy GIS data driver on the file server in zone 1, obtain grid spatial data, deploy geographic base map vector data and raster data in zone 1, and synchronize data to the file server in zone 3 based on the file synchronization solution of the grid control system;

[0006] Step 2: In the editor of the CIM / G file of the power grid application scenario, create a new HTML component, specify the index.html file path of the three-area GIS integration component of the power grid control system loaded by the component, and set other style properties;

[0007] Step 3: When the CIM / G file of the power grid application scenario is loaded, the system will automatically initialize the HTML component, obtain the index.html path and file content configured in the e_option attribute by reading the attribute items of the component, and further obtain the Javascript and css static resource content through the reference information of the JavaScript file in the HTML. When the HTML component is loaded, the system triggers the loading completion event, which calls the map initialization script in index.html.

[0008] Step 4. The JavaScript code in index.html calls the map initialization function and sets it according to the application scenario requirements;

[0009] Step 5: Based on the configured layer data source information, asynchronously load the data resources required for the geographic base map and layer through the getfile or getdata service.

[0010] Step 6: After data parsing and layer loading are completed, the custom event definition is triggered. In the power grid application scenario CIM / G file, the OnMessageChange event handler determines the specific response operation to be performed based on the layer name and event name information. For example, after obtaining the information of the selected element of the layer, it executes the user interaction event that processes the content of the layer.

[0011] Furthermore, in step 1, the file synchronization program deployed in the power grid control system monitors the changes in files and directories in areas 1 and 3 and calls the file transfer and management services, thereby achieving consistency between the files in the file servers 1 and 3. Based on the file synchronization mechanism of the power grid control system, the GIS data files deployed in area 1 will be synchronized to the same directory on the file server in area 3.

[0012] Furthermore, in step 2, other style attributes include width and height.

[0013] Furthermore, in step 2, the HTML component is an HTML component defined in a QT-based human-machine browser / editor, and the component implements a customized function by associating index.html in different program packages.

[0014] Furthermore, the loading process of the HTML component includes loading the index.html file and its associated JavaScript resources, and triggering a loading completion event after the loading is complete.

[0015] Furthermore, in step 4, the map view, layer feature type, layer style, and layer data source are set.

[0016] Furthermore, in step 5, the asynchronously loaded data file resources include file resources obtained through the getfile service and data resources obtained through the getdata service.

[0017] Accordingly, an application calling system based on the one-three-area GIS integrated component of the power grid control system includes: a one-area file server, a three-area file server, a power grid application scenario CIM / G file, and a one-three-area GIS integrated component of the power grid control system; deploying a GIS data driver in the one-area file server to obtain power grid grid spatial data, and deploying geographic base map vector data and raster data in the one area, and synchronizing the data to the three-area file server based on the file synchronization solution of the power grid control system; in the editor of the power grid application scenario CIM / G file, creating a new HTML component, and specifying the index.html file path of the one-three-area GIS integrated component of the power grid control system to be loaded by the component; when the power grid application scenario CIM / G file is loaded, the system automatically initializes the HTML component, loads the associated index.html and JavaScript files, calls the map initialization function, asynchronously loads the data resources required for the geographic base map and the layer, and the OnMessageChange event handler of the power grid application scenario CIM / G file determines the specific response operation to be executed according to the layer name and event name information.

[0018] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: the present invention provides a three-zone GIS integrated component for a power grid control system, defines an HTML component in a power grid application scenario CIM / G file, and associates it with the index.html file of the component; calls the layer and map initialization interface of the HTML component in the script of the power grid application scenario CIM / G file; parses data file resources, triggers a custom event definition after the layer is loaded, parses event information in the OnMessageChange event processing of the power grid application scenario CIM / G file, and executes corresponding response operations. Through a unified interface and event mechanism, the same set of implementation programs are used for the GIS screens of the one-zone and three-zone power grid applications, thereby reducing the cost of application development and deployment.
