Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0058] Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor systems and / or microcontroller systems.

[0059] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0060] This invention provides a method, apparatus, electronic device, and storage medium for metallurgical general drawing, which will be described below.

[0061] Figure 1 This is a schematic flowchart of an embodiment of the metallurgical general drawing method provided by the present invention, as shown below. Figure 1 As shown, the methods for drawing general metallurgical plans include:

[0062] S101. Obtain the general map mapping dataset of the map to be drawn, and set the metallurgical general map mapping standard specifications;

[0063] S102. Classify and store the general map mapping dataset according to the metallurgical general map drawing standards and specifications to obtain the metallurgical general map database;

[0064] S103. Perform vector slicing on the metallurgical general diagram database to obtain a vector slice dataset;

[0065] S104. Based on the vector tile dataset, the map to be drawn is plotted to obtain the overall metallurgical map.

[0066] Compared with existing technologies, the metallurgical general map mapping method provided by this invention establishes a standard specification for metallurgical general map mapping. This standard specification allows for the unified setting and referencing of data obtained from vector slices in the metallurgical general map, thereby avoiding redundant data storage and the resulting redundancy in the vector slice electronic map. Furthermore, by using the standard specification for metallurgical general map mapping, all data in the vector slice data is standardized in naming and encoding, which reduces complexity and improves efficiency when creating and updating the metallurgical general map.

[0067] It should be understood that the general map survey dataset obtained in step S101 can be obtained from the cartographic tool or by calling the historically stored general map survey dataset from the storage medium.

[0068] In a specific embodiment of the present invention, the metallurgical general mapping standard specification can be compiled based on the classification and code of basic geographic information elements and the metallurgical engineering surveying specification, supplemented and improved in combination with the actual situation of steel enterprises. In the metallurgical general mapping standard specification, the features of the plant area can be divided into positioning foundation, water system, residential area and facilities, transportation, boundary, landform and soil, vegetation, pipeline, map decoration and metallurgical. The element types include symbol points, simple undirected lines, simple directed lines, composite entities, surface entities and annotations.

[0069] It should be noted that, in order to process the mapping dataset according to the metallurgical general drawing standards and specifications, in some embodiments of the present invention, step S102 includes:

[0070] According to the metallurgical general map mapping standard, a three-layer organizational structure is determined. The three-layer organizational structure is: general map mapping dataset - local feature type classification dataset - feature set of each element type. Local feature type classification datasets include basic feature categories and pipeline categories. Feature set of each element type includes a preset number of elements.

[0071] The data in the general map survey dataset are classified according to basic land cover type and pipeline type to obtain basic land cover type dataset and pipeline type dataset;

[0072] The basic feature dataset and pipeline dataset are classified according to a preset number of features to obtain a preset number of basic feature sub-feature datasets and a preset number of pipeline sub-feature datasets.

[0073] The data is named according to the local land cover type and element type of each sub-feature dataset in the preset number of basic land cover type sub-feature datasets and the preset number of pipeline type sub-feature datasets. The data in each sub-feature dataset is stored to obtain a metallurgical general map database that conforms to the metallurgical general map mapping standard specifications.

[0074] In a specific embodiment of this invention, the surveying data of the steel plant area can be organized and stored in a hierarchical manner according to standards, forming a three-layer organizational structure of "general map dataset - local feature type classification dataset - feature set of each element type". Feature types can be specifically divided into basic feature types and pipeline types. Basic features can include survey control points, water systems and their appurtenances, buildings and structures, transportation and its ancillary facilities, regional boundaries, landforms and soil, and vegetation. Pipeline types can include power pipes, communication pipes, water supply pipes, sewage pipes, gas pipes, heating pipes, industrial gas pipes, industrial water pipes, industrial chemical pipes, and other industrial pipes. The next layer below each feature type can be divided into area features, solid line features, auxiliary line features, point features, and annotation features according to element type. This ultimately forms a standardized metallurgical general map database, where each sub-element can be standardized and named according to "feature type + element type".

[0075] It should be noted that in order to perform vector slicing, the metallurgical general drawing database needs to be preprocessed first. In some embodiments of the present invention, step S103 includes:

[0076] The metallurgical general layout database is preprocessed to obtain a dataset in the target format.

[0077] The target format dataset is vector-sliced ​​to obtain a vector-sliced ​​dataset.

[0078] Specifically, this invention can preprocess the metallurgical general drawing database to ensure consistency in format and coordinate system, thereby obtaining a target format dataset.

[0079] In some embodiments of the present invention, the metallurgical general layout database is preprocessed to obtain a target format dataset, including:

[0080] The coordinate systems of the data in each layer of the metallurgical general map database are transformed to obtain the geographic coordinate system metallurgical general map dataset;

[0081] The data format of the geographic coordinate system metallurgical general map dataset is converted to obtain the target format dataset. Each layer of data in the geographic coordinate system metallurgical general map dataset generates a corresponding target format file, and the target format dataset includes all target format files of all layer data.

[0082] In a specific embodiment of the present invention, the metallurgical general map database may include coordinate transformation and format conversion to meet the data standard requirements of vector tiling. Coordinate transformation converts the data of each layer in the metallurgical general map database from the plant's custom coordinate system to the WGS84 coordinate system, resulting in a geographic coordinate system metallurgical general map dataset. Specifically, the data of each layer in the metallurgical general map database can be converted to common coordinate systems such as CGCS2000 and WGS84, or internet coordinate systems such as GCJ02 and BD09, according to the actual application requirements of the metallurgical general map. Plant-custom coordinate systems are also supported. Then, a GeoJSON (geographic data) dataset in the target coordinate system is generated, i.e., the geographic coordinate system metallurgical general map dataset. The geographic coordinate system metallurgical general map dataset is also organized in a three-level manner and named according to the metallurgical general map specifications.

[0083] In some embodiments of the present invention, vector slicing is performed on the target format dataset to obtain a vector slice dataset, including:

[0084] The target format dataset is sliced ​​using a preset slicing tool to obtain a preset number of sliced ​​data.

[0085] The hierarchy, rows, and columns of each slice data are encoded and saved according to the slice hierarchy in the preset slicing tool, resulting in a vector slice dataset containing a preset number of slice data.

[0086] In a specific embodiment of this invention, the Tippecanoe tool can be used to perform vector tiling on the GeoJSON dataset (target format dataset). The vector tiling covers the entire factory area, and the tiling level can be 0-21. The output format of the tiling is Mbtiles, ultimately generating an MBtiles dataset, i.e., a vector tile dataset. MBTiles (tile data) is a general format for storing geographic vector tile data, where each tile is encoded with a specific level, row, and column and saved as vector data. This format can efficiently store and transmit large amounts of geographic data, while supporting fast data reading and rendering. MBtiles data is organized in a two-layer structure of "file-layer". One GeoJSON dataset corresponds to one Mbtiles file, and one file in the GeoJSON dataset corresponds to one layer in the Mbtiles dataset. Mbtiles files are named according to the factory area name, and each layer is consistent with the sub-features in the database, named according to "feature type + feature type". The compliant Mbtiles dataset is then deployed to a server.

[0087] It should be noted that, in order to draft according to the metallurgical general drawing standards and specifications, in some embodiments of the present invention, the preset number of elements includes area symbols, line symbols, and annotation symbols; step S104 includes:

[0088] Based on the area symbols, line symbols, or annotation symbols, determine the area symbol sub-feature dataset, line symbol sub-feature dataset, or annotation symbol sub-feature dataset in the vector tile dataset;

[0089] By setting the attributes of the data in the area symbol sub-feature dataset, line symbol sub-feature dataset, or annotation symbol sub-feature dataset of the map to be drawn, the metallurgical general map is obtained.

[0090] In a specific embodiment of the present invention, cartography personnel can create a map to be drawn in a cartographic tool according to the metallurgical general map cartographic standard specifications. The preset number of tile data can include a dataset of sub-elements corresponding to area symbols, a dataset of sub-elements corresponding to line symbols, a dataset of sub-elements corresponding to annotation symbols, and a dataset of sub-elements corresponding to point symbols. After determining the sub-element dataset corresponding to each symbol, parameters for the corresponding sub-element dataset of the map to be drawn can be set in the cartographic tool. These settings include display parameters such as color, transparency, outline color, outline width, and outline transparency for area symbol sub-elements; attributes such as color, line width, offset, and connectivity for line symbol sub-elements; and display parameters such as font, font size, color, position, halo, and rotation mode for annotation symbol sub-elements. When setting the attributes of the line symbol sub-elements dataset, the cartographic tool provides two basic line types: solid lines and dashed lines. For dashed lines, the dashed line interval can be flexibly set to standardize the map display. For complex line types, multiple basic line types can be superimposed and combined to complete complex drawings. For example... Figure 2 As shown, Figure 2 The image represents an "unreinforced slope" in the landform and soil category. The symbol is an overlay image, the layer it belongs to is its position in the vector tile, and the feature code is obtained by encoding according to MBTiles.

[0091] In some embodiments of the present invention, the preset number of elements includes dot-shaped symbols; step S104 includes:

[0092] The image icon set should be set according to the metallurgical general drawing standard specifications;

[0093] Encode and store all image icons in the image icon set to obtain a sprite sheet;

[0094] Based on the sprite sheet and dot symbols, the map to be drawn is plotted to obtain the overall metallurgical map.

[0095] In a specific embodiment of the present invention, an SVG icon for each item can be created according to the metallurgical general mapping standard, with the specific naming format being "feature type - six-digit feature code", thus obtaining an SVG icon set for all SVG icons, such as... Figure 3 As shown, Figure 3 To create a subset of SVG icons, the Vite plugin can be used to generate a sprite sheet based on the SVG icon set. This allows all SVG icons to be stored in a single sprite sheet, with the names derived from a specific naming format serving as the codes for each SVG icon. Alternatively, the sprite sheet can be stored on a server integrated with the icon creation system.

[0096] In some embodiments of the present invention, a general metallurgical map is obtained by drawing a map based on a sprite sheet and dot symbols, including:

[0097] Based on the dot symbols, determine the dot symbol sub-feature dataset in the vector tile dataset;

[0098] In the map to be drawn, the image icons in the sprite sheet are referenced according to the dot symbol sub-feature dataset and the code corresponding to each image icon to obtain the initial metallurgical general map;

[0099] The attributes of the data in the point symbol sub-feature dataset of the initial metallurgical general map are set to obtain the metallurgical general map.

[0100] In a specific embodiment of the present invention, a corresponding dot symbol sub-feature dataset can be obtained based on the dot symbols. Then, the "icon-image" attribute of the layer can be set. Alternatively, based on a sprite sheet, SVG icons can be referenced through the encoding of each SVG icon, thereby adding the specified SVG icon to the map of the cartographic tool. Furthermore, display parameters such as the size, offset, rotation mode, etc., of the dot symbols can be set to standardize the map display, thus obtaining a general metallurgical map.

[0101] In some embodiments of the present invention, after mapping the map to be drawn based on the vector tile dataset to obtain the overall metallurgical map, the method further includes:

[0102] The basic parameters of the metallurgical general layout are set, and all the data of the metallurgical general layout are integrated to obtain the target file of the metallurgical general layout;

[0103] Publish the metallurgical general layout and metallurgical general layout target documents.

[0104] In a specific embodiment of the present invention, after obtaining the metallurgical general map, it is necessary to set the basic parameters of the map, where "center" is the center point of the map, "zoom" is the minimum display level, "source" is the address of the map's vector tile resource, "sprite" is the address of the symbol library (sprite sheet) resource, "glyphs" is the address of the font library resource, etc. Each basic parameter and resource, together with the description of each layer, forms a complete StyleJSON file, which is the metallurgical general map target file. After completing all the above steps, the metallurgical general map target file and the metallurgical general map can also be published as a vector map service. After successful publication, the URL address of the map is automatically generated, and the metallurgical general map can be displayed and browsed on the front end.
