DETAILED DESCRIPTION

[0018] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0019] The present application proposes a method and system for generating a multi-scale model of a laneway based on a laneway cross section, the method comprising: obtaining a laneway cross-section diagram of the laneway to be modeled, and determining each graphic element contained in the laneway cross-section diagram that needs to be represented in the laneway multi-scale model; classifying each graphic element based on a preset model category to obtain the model category to which each graphic element belongs, wherein the preset model category includes: continuous stretching model, discontinuous stretching model and point model; generating an initial model of each graphic element according to the model category to which each graphic element belongs; combining the initial models of each graphic element to obtain a multi-scale model of the laneway to be modeled. The technical solution proposed in the present application can make full use of the existing laneway cross-section diagrams in the coal mine engineering design, quickly generate a laneway multi-scale model, and solve the problem of heavy workload and long time consumption in laneway modeling.

[0020] The following describes a method and system for generating a multi-scale model of a tunnel based on a tunnel section according to an embodiment of the present application with reference to the accompanying drawings.

[0021] Embodiment 1 Figure 1 A flowchart of a method for generating a multi-scale model of a tunnel based on a tunnel section according to an embodiment of the present application is shown in FIG. Figure 1 As shown, the method includes: Step 1: Obtain a cross-sectional view of the lane to be modeled, and determine various graphic elements contained in the cross-sectional view that need to be represented in the lane multi-scale model.

[0022] In the embodiment of the present disclosure, the graphic elements that need to be represented in the multi-scale model of the lane may include: Tunnel arches and walls, floor plates, gutters, ditch covers, rails, sleepers, pipes, pipe supports and pipe clamps, cables, and cable hooks.

[0023] It should be noted that in the mine design of coal mining projects, it is necessary to design the tunnel cross-section diagram. The tunnel cross-section diagram is composed of a series of two-dimensional graphic symbols, including tunnel contours, ditches, covers, pipes, pipe supports, equipment, etc.

[0024] For example, Figure 2 This is a cross-section of a tunnel in a coal mine. The cross-section includes the tunnel arch, wall, floor, ditch, ditch cover, sleeper, rail, cable, cable hook, pipeline, pipeline support and pipe clamp, and mine car outline graphic elements. For clear expression, the shape and positioning dimensions of the tunnel, equipment or facilities are hidden in the figure. The relative position between models has been defined in the cross-section, and there is no need to adjust the position during model generation.

[0025] Step 2: Classify the graphic elements based on preset model categories to obtain the model category to which each graphic element belongs, wherein the preset model categories include: continuous stretching model, discontinuous stretching model and point model.

[0026] In the embodiment of the present disclosure, the classifying the graphic elements based on the preset model category to obtain the model category to which the graphic elements belong includes: Classifying the tunnel arch and wall, the floor, the ditch, the pipeline and the cable as a continuous tensile model; Classifying the ditch cover and the rail as an intermittent tensile model; The rail sleepers, the pipe supports and pipe clamps, and the cable hooks are classified as point models.

[0027] It should be noted that the continuous stretching model refers to a model that can be generated based on a given section and path, and the model is continuous, such as a tunnel model, a cable model, etc.; The discontinuous stretch model refers to a model that can be generated based on the cross section and path, but the model is interrupted at a certain distance, and the interrupted models are connected end to end, such as the ditch cover model, rail model, etc. Point models refer to multiple repetitive models arranged along the length of the tunnel, such as pipe support models, cable hook models, lamp models, sleeper models, etc. These models are placed along the path with fixed model spacing. If the two-dimensional graphic elements in the cross-section view cannot meet the expression needs, they need to be generated through parameters or obtained from the model library.

[0028] For example, Figure 2 For example, the classification results of different graphic elements are shown in Table 1. Since the mine car outline is used to express the space required for the mine car to pass through this section of the tunnel, it can be excluded from the model of this section of the tunnel. As can be seen from the table, except for the mine car outline, the graphic elements in the tunnel section can be classified into one of the three model categories.

[0029] Table 1 Classification of graphic elements

[0030] Step 3: Generate an initial model of each graphic element according to the model category to which each graphic element belongs.

[0031] In the embodiment of the present disclosure, step 3 specifically includes: 1. When the model category to which the graphic element belongs is a continuous stretching model, Determine the cross-sectional shape of the graphic element in the tunnel cross-sectional view by picking up contour lines or creating regions; Taking the center line of the graphic element as the stretching path; Generate an initial continuous stretching model of the graphic element based on the cross-sectional shape and the stretching path; It should be noted that Figure 2 For example, the cross-sectional shape of the tunnel arch and wall can be created by picking the contour line, or by creating the area, and the stretching path is the specified center line.

[0032] At the same time, the method for defining the cross-sectional shape of the bottom plate, ditch and cable is the same as that of the tunnel arch and wall.

[0033] 2. When the model category to which the graphic element belongs is the discontinuous stretch model, Determine the cross-sectional shape of the graphic element in the tunnel cross-sectional view by picking up contour lines or creating regions; Taking the center line of the graphic element as the stretching path; The preset interruption distance is used as the interruption distance; Generate an initial discontinuous stretching model of the graphic element based on the cross-sectional shape, the stretching path and the interruption distance; It should be noted that Figure 2 For example, the generation of the intermittent stretching model requires the definition of its cross-sectional shape, stretching path, and interruption distance. The cross-sectional shape of the track can be created by picking the contour line or by creating an area. The stretching path is the specified track centerline, and the interruption distance is generally 12.5m or 25m, that is, when the rail section is stretched along the track centerline, it is interrupted every 12.5m or 25m. The cross-sectional shape, path, and interruption distance of the ditch cover are defined in a similar way, and the interruption distance of the ditch cover is related to its own specifications.

[0034] 3. When the model category to which the graphic element belongs is a point model, Acquire the parameters of the graphic element, and generate an initial single point model of the graphic element by using a parametric modeling method; Determining the placement path, placement spacing and center line of the graphic element; An initial series of point models of the graphic element is generated based on the single point model of the graphic element, the placement path, the placement spacing and the center line.

[0035] It should be noted that parametric modeling mainly refers to a modeling method that uses parameters to describe the geometric features of a model, creates a model by inputting specified parameters, and controls the geometric shape and characteristics of the model by adjusting the parameters. Non-geometric feature information in the model is generally attached to the model in the form of associated information. For example, model name, manufacturer name, equipment name, etc.

[0036] Furthermore, when the model category to which the graphic element belongs is a point model, the method further includes: An initial single point model of the graphic element is found from a pre-established graphic element model library.

[0037] It should be noted that the graphic element model library can be formed by manually modeling each image element and storing it in a designated graphic file, or by using a modeling tool to model each image element to form a graphic element model library.

[0038] It should be noted that Figure 2 For example, if the two-dimensional graphic elements in the tunnel cross-section diagram cannot meet the expression needs of the point model, a single point model can be generated through parameters or obtained from the graphic element model library. When the series is generated, the placement path and placement spacing must be given. When generated through parameters, the generation method of its parametric model needs to be implemented; when obtained from the graphic element model library, the graphic element model library needs to be established in advance.

[0039] by Figure 2 Taking the pipe supports and pipe clamps in as an example, the model can be generated by inputting parameters such as support type, pipe clamp type, pipe diameter, and support length, using parametric modeling. The placement path of the pipe support and pipe clamp model is the center line of the pipeline, and the placement spacing is related to the pipeline diameter. For example, the spacing between DN150 pipe supports and pipe clamps can be 3m.

[0040] Parametric modeling is a conventional modeling method. Common parametric modeling tools such as Microstation, Revit, Solidworks, etc. all have similar functions. Taking a rectangular block as an example, you can generate a rectangular block by inputting the length, width, and height in Microstation, Revit, or Solidworks tools and then specifying the position with the mouse cursor.

[0041] Step 4: Combine the initial models of the graphic elements to obtain a multi-scale model of the lane to be modeled.

[0042] In the embodiment of the present disclosure, step 4 specifically includes: The initial continuous stretching model of each graphic element whose model category is the continuous stretching model, the initial discontinuous stretching model of each graphic element whose model category is the discontinuous stretching model, and the initial series of point models of each graphic element whose model category is the point model are combined to generate a multi-scale model of the lane to be modeled.

[0043] It should be noted that the technical solution can be implemented by computer development. When defining different types of models, different identifiers should be pre-defined or added in real time for different graphic elements so that the computer program can identify different graphic elements, prompt the required input or specified parameters, and generate models. The detailed implementation process of the technical solution can be as follows: Figure 3 As shown, Figure 3 The model of the tunnel and internal equipment (facility) is the multi-scale model of the tunnel.

[0044] It should be noted that the models in this application can be established using software such as Microstation, Revit, or Solidworks with three-dimensional modeling capabilities.

[0045] The method for generating a multi-scale model of a tunnel based on a tunnel section provided in this embodiment divides the models generated by different graphic elements in the tunnel cross-section diagram into three types: continuous stretching model, discontinuous stretching model, and point model. A continuous stretching model is generated by defining the cross-section shape and the stretching path; a discontinuous stretching model is generated by defining the cross-section shape and the stretching path and inputting the interruption distance; a series of point models are generated by generating a single point model, placing the path, and placing the spacing. This method can make full use of the existing tunnel cross-section diagrams in the coal mine engineering design, quickly generate a multi-scale model of the tunnel, and solve the problem of large workload and long time consumption in tunnel modeling.

[0046] To sum up, the method for generating a tunnel multi-scale model based on the tunnel cross-section proposed in this embodiment can make full use of the existing tunnel cross-section drawings in the coal mine engineering design, quickly generate a tunnel multi-scale model, and solve the problem of large workload and long time consumption in tunnel modeling.
