[0068] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0069] Example 1

[0070] Please see Figure 1 , Figure 1 A schematic flow chart of a modeling method based on a railway transportation line is provided for an embodiment of the present application. The modeling method based on a railway transportation line includes:

[0071] S101. Obtain a CAD drawing of a railway transportation route.

[0072] In this embodiment, the CAD drawing in the method is a CAD drawing of a railway transportation line in a steel plant.

[0073] S102, simplifying the CAD graphics to obtain a path line diagram.

[0074] In this embodiment, after simplifying the CAD graphics, a path line diagram containing only path lines can be obtained.

[0075] S103, extracting the vertex coordinates and line segment lengths of all line segments in the path line graph through the CAD plug-in.

[0076] In this embodiment, the CAD plug-in is a secondary developed plug-in.

[0077] In this embodiment, the vertex coordinates and line segment lengths of all line segments in the path line graph can be extracted through the secondary developed CAD plug-in.

[0078] By implementing this embodiment, graphic parameters can be batch-proposed through the secondary developed CAD program plug-in, thereby improving the accuracy of simulation input data conversion.

[0079] In this embodiment, the method can store the vertex coordinates and line segment lengths of all extracted line segments in an Excel table, which is referred to as a first table in this embodiment.

[0080] S104, decomposing the path line graph to obtain a straight line line graph.

[0081] In this embodiment, the method can decompose the path line graph to obtain a straight line line graph including only straight lines.

[0082] In this embodiment, the path line graph includes various line segments, while the straight line graph may only include line segments in the horizontal or vertical direction. Alternatively, the straight line graph only includes longer line segments. In short, the method can filter out unwanted lines in the path line graph by decomposition, thereby obtaining a suitable straight line graph.

[0083] S105: extracting graphic attribute parameters of the straight line graph.

[0084] In this embodiment, the graphic attribute parameters include the overall layout of the straight line graph and all parameters of the straight lines.

[0085] In this embodiment, the method can store the extracted graphic attribute parameters in an Excel table, which is referred to as a second table in this embodiment.

[0086] By implementing this implementation method, it is possible to export parameter information of all transportation routes in the CAD drawing to form an Excel file, and then import it into the simulation platform in batches. Compared with manual individual entry, batch processing improves the overall processing speed and saves time; at the same time, it avoids errors such as data dislocation that are prone to occur during manual entry, thereby improving the accuracy of input data of the simulation platform.

[0087] It can be seen that the real-time steps S101 to S105 can automatically extract CAD graphic parameters, thereby greatly reducing the time for importing the graphic attributes of the path into the simulation platform.

[0088] S106. Select a reference line segment in the graphic attribute parameters.

[0089] In this embodiment, before this step, the method sets up an empty model in the digital logistics simulation platform PlantSimulation, which is called the original model, and imports the above-mentioned first table and second table into the original model.

[0090] In this embodiment, the method selects a reference line segment from the graphic attribute parameters for reference.

[0091] S107: Setting a reference object corresponding to the reference line segment in the preset original model.

[0092] In this embodiment, the original model is an empty model in the digital logistics simulation platform PlantSimulation.

[0093] In this embodiment, the method sets a reference object corresponding to the reference line segment in PlantSimulation. Since the final model is to be automatically generated according to the CAD drawing, the method needs to determine a reference object in the original model. For example, when modeling is performed from left to right based on the reference line segment according to the CAD drawing, the method can perform modeling from left to right based on the reference object.

[0094] In this embodiment, setting a reference object is conducive to accurate automated modeling, and the model can also be scaled and adjusted according to the reference object.

[0095] S108. Using the reference object as a reference, creating a track frame and multiple track objects of the railway transportation line in the original model according to the graphic attribute parameters; the multiple track objects correspond to all the line segments.

[0096] In this embodiment, the method can create a track framework of a railway transportation line according to the graphic attribute parameters.

[0097] In this embodiment, because the image attribute parameters include reference line segments and the reference object is set in the original model, the relationship between the reference object and other objects is determined according to the relationship between the straight lines in the image attribute parameters, and the track framework of the railway transportation line can be created.

[0098] In this embodiment, the multiple track objects created at this time are not installed in the track frame. In other words, the track frame only has the approximate positions of the track objects, and no actual track objects are established.

[0099] In this embodiment, multiple track objects can be stored anywhere, such as in a cache.

[0100] In this embodiment, multiple track objects may be class objects in this process.

[0101] S109, scaling the track frame based on the reference object and a preset scaling ratio.

[0102] In this embodiment, the method can scale the track frame, and can also scale the reference object and the track object.

[0103] S110, performing calculations according to the vertex coordinates and line segment lengths of all line segments and a preset scaling ratio to obtain a segmentation parameter table; and determining the relative positional relationship between all line segments.

[0104] In this embodiment, the segment parameter table includes object length values ​​of all track objects.

[0105] S111. Calculate coordinate parameters of multiple track objects according to the segment parameter table and the relative position relationship.

[0106] In this embodiment, the method can determine the coordinate parameters of all track objects based on the reference object.

[0107] In this embodiment, the coordinate parameters are the X coordinate and Y coordinate of the track object in PlantSimulation.

[0108] S112. According to the graphic attribute parameters and the coordinate parameters, the coordinate positions of multiple track objects are set in the original model of the created track framework to obtain a preliminary model of the railway transportation line.

[0109] In this embodiment, the method sets the track object in the track frame according to the actual coordinates to obtain a preliminary model with the track object.

[0110] S113. Processing multiple track objects in the preliminary model.

[0111] As an optional implementation, the step of processing a plurality of track objects in the preliminary model includes:

[0112] In the preliminary model, determine whether the track object is an arc object;

[0113] When the track object is an arc object, the track object is adjusted according to the line parameter table corresponding to the track object in multiple attribute parameters, the setting of the chamfer angle, the center angle and the radius, and the modeling horizontal direction.

[0114] In this embodiment, the method can adjust the corresponding direction according to the modeling horizontal direction.

[0115] In this embodiment, the modeling horizontal direction is from left to right (positive direction of the X-axis) or from right to left (negative direction of the X-axis).

[0116] As an optional implementation, the step of processing a plurality of track objects in the preliminary model includes:

[0117] In the preliminary model, determine whether the track object is an arc object;

[0118] When the track object is not an arc object, parameters of the track object are adjusted according to a line parameter table corresponding to the track object in a plurality of attribute parameters, a set chamfer angle and a length.

[0119] By implementing this embodiment, the degree of the central angle of the circle can be reversely calculated through the length and radius of the arc, so that the calculation result can be accurate to 4 decimal places, providing more accurate input data for the simulation platform and improving the accuracy of the overall simulation data.

[0120] S114. Determine multiple spacing ranges between the multiple track objects according to the head-to-tail coordinate relationship between the multiple track objects.

[0121] S115. Automatically create a connection relationship between multiple track objects according to the head-to-tail coordinate relationship and multiple spacing ranges to obtain a final model of the railway transportation line.

[0122] In this embodiment, all track models can be connected according to the head-to-tail coordinate relationship and multiple spacing ranges to obtain a final model of the railway transportation line.

[0123] It can be seen that the implementation of this implementation method can achieve rapid synchronous update and iteration in the simulation platform PlantSimulation when the path graph changes, thereby realizing rapid changes in the corresponding project.

[0124] In the embodiment of the present application, the execution subject of the method can be a computing device such as a computer or a server, and no limitation is made in this embodiment.

[0125] In the embodiment of the present application, the execution subject of the method can also be a smart device such as a smart phone, a tablet computer, etc., and there is no limitation on this in the present embodiment.

[0126] It can be seen that the modeling method based on railway transportation routes described in this embodiment can automatically identify the path direction defined by the simulation platform, and then automatically generate the path model by converting the CAD graphic data, compared with manually creating the path model; at the same time, the logical connection relationship of the path model can be automatically completed through data recognition. Compared with manual creation, when the amount of graphic data is large, the efficiency of simulation modeling can be significantly improved, and errors caused by manual operation can be avoided.
