For example, the steps described in this application can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution disclosed in this application can be achieved, and this is not limited herein.

[0032] In related technologies, track-passing pipes and channel-passing pipes are installed inside the secondary lining space of tunnels. Since the secondary lining space has a certain curvature, the shapes of the track-passing pipes and channel-passing pipes must match the shape of the secondary lining. However, existing methods for generating 3D models of track-passing pipes or channel-passing pipes typically involve manual generation of the entire 3D model, resulting in low generation efficiency and a high risk of errors, which can affect the subsequent physical construction process.

[0033] To address the aforementioned issues, this disclosure provides a method and apparatus for generating a model of pre-embedded pipelines for electrical, signaling, and communication systems in tunnels. In response to an instruction to generate a first pipeline model, the method acquires a target tunnel model and a pre-drawn two-dimensional trajectory line of the first pipeline; it acquires configuration information for the first pipeline model, including a first positional relationship between the first pipeline model and the target tunnel model, and a first included angle between the first pipeline and the target tunnel model; based on the two-dimensional trajectory line of the pipeline, the first positional relationship, and the first included angle, it generates a three-dimensional trajectory line of the first pipeline at a three-dimensional target position in the target tunnel model; and based on the three-dimensional trajectory line, it generates a three-dimensional model of the first pipeline at the three-dimensional target position. This achieves automatic generation of three-dimensional models of pipelines passing through tracks or trenches, improving the generation efficiency and accuracy of pre-embedded pipeline models for electrical, signaling, and communication systems.

[0034] Figure 1 This is a flowchart illustrating a method for generating a model of pre-embedded pipes for four electrical systems in a tunnel, according to an exemplary embodiment. Figure 1 As shown, it should be noted that the tunnel electrical and electronic pre-embedded pipe model generation method of this application embodiment is applied in the tunnel electrical and electronic pre-embedded pipe model generation device. For example... Figure 1 As shown, the method may include the following steps:

[0035] Step 101: In response to receiving an instruction to generate a first pipeline model, acquire the target tunnel model and the pre-drawn two-dimensional trajectory line of the first pipeline.

[0036] Wherein, the size of the two-dimensional trajectory line 1 of the first pipeline corresponds to the size of the cross section 2 of the target tunnel model; the first pipeline is a track-passing pipe or a trench-passing pipe.

[0037] In one embodiment, the first two-dimensional trajectory line 1 of the pipeline can be drawn by the user on the cross-sectional surface of the target tunnel model. Alternatively, the first two-dimensional trajectory line 1 of the pipeline can be drawn within the cross-sectional surface at the bottom of the secondary lining model 3 in the aforementioned cross-sectional surface.

[0038] like Figure 2 As shown, the track pipes are all connected to the two cable troughs 4 models inside the tunnel, and the two cable troughs 4 are located on both sides of the internal space of the tunnel model.

[0039] Step 102: Obtain the configuration information of the first pipeline model.

[0040] The configuration information includes the first positional relationship between the first pipeline model and the target tunnel model 5, and the first included angle between the first pipeline and the target tunnel model 5.

[0041] In one embodiment, the first positional relationship can be the position of the first pipe model on the mileage line 6 of the template tunnel model. The first included angle can be the angle between the first pipe model and the mileage line 6 projected onto the XY plane.

[0042] Step 103: Based on the first pipeline's two-dimensional trajectory line, the first positional relationship, and the first included angle, generate the three-dimensional trajectory line of the first pipeline at the three-dimensional target position in the target tunnel model.

[0043] Understandably, in order to generate a three-dimensional pipeline model, it is necessary to convert the two-dimensional trajectory lines into three-dimensional trajectory lines.

[0044] Therefore, in one embodiment, the three-dimensional trajectory line of the first pipeline can be generated at the three-dimensional target position in the target tunnel model 5 based on the first two-dimensional trajectory line 1 of the first pipeline, the first positional relationship, and the first included angle.

[0045] The first positional relationship and the first included angle can be preset according to actual needs.

[0046] In some embodiments of this application, such as Figure 3 , Figure 4As shown, the first positional relationship is the coordinates 9 of the two-dimensional intersection point of the first pipeline model and the tunnel mileage line 6 in the target tunnel model 5; the first pipeline two-dimensional trajectory line 1 is a two-dimensional trajectory line on the XY plane, and step 103 may specifically include:

[0047] Step a1: Determine the position of the three-dimensional target based on the position information of the target tunnel model 5 and the coordinates of the two-dimensional intersection point 9.

[0048] In some embodiments of this application, step a1 may specifically include the following steps:

[0049] Step a11: Obtain the location information of the target tunnel model 5.

[0050] The location information includes the horizontal curve information and vertical curve information of the target tunnel model 5.

[0051] Step a12: Using the flat curve information and the two-dimensional intersection coordinates 9, determine the X-axis coordinates and Y-axis coordinates corresponding to the three-dimensional target position.

[0052] In one embodiment, the X-axis coordinates and Y-axis coordinates corresponding to the three-dimensional target position can be determined based on a preset first pipeline centerline, that is, the two-dimensional information can be determined.

[0053] Step a13: Determine the Z-axis coordinates corresponding to the three-dimensional target position based on the vertical curve information.

[0054] In one embodiment, the Z-axis coordinates corresponding to the three-dimensional target position can be determined based on the vertical curve information, that is, the elevation information can be determined.

[0055] Step a14: Obtain the three-dimensional target position based on the X-axis coordinate, Y-axis coordinate, and Z-axis coordinate corresponding to the three-dimensional target position.

[0056] Step a2: Move the first two-dimensional trajectory line 1 of the pipeline to the three-dimensional target position.

[0057] Step a3: Rotate the first pipeline two-dimensional trajectory line 1 according to the tunnel mileage line 6 to obtain the rotated two-dimensional trajectory line of the track pipe.

[0058] In one embodiment, the rotated two-dimensional trajectory line of the rail tube is perpendicular to the tunnel mileage line 6, and the rotated two-dimensional trajectory line of the rail tube is located in the YZ plane.

[0059] Step a4: Based on the first included angle and the three-dimensional target position, determine the target plane 8 perpendicular to the XY plane.

[0060] The three-dimensional target position is located in the target plane 8.

[0061] In some embodiments of this application, such as Figure 3 As shown, step a4 may specifically include the following steps:

[0062] Generate an intermediate plane including the position of the three-dimensional target based on the YZ plane;

[0063] The intermediate plane is rotated about the first straight line as the axis of rotation until it forms an angle with the tunnel mileage line 6, which is the first angle. The first straight line is perpendicular to the XY plane, and the X-axis coordinates and Y-axis coordinates of the first straight line are the coordinates of the intersection of the tunnel mileage line 6 and the first pipeline two-dimensional trajectory line 1.

[0064] In one embodiment, the YZ plane with the three-dimensional target position as the origin is defined as the intermediate plane, and a first straight line on the intermediate plane, including the three-dimensional target position and perpendicular to the XY plane, is rotated around the first straight line to a position where the angle between the intermediate plane and the tunnel mileage line 6 is the first angle.

[0065] Step a5: Project the rotated first two-dimensional trajectory line 1 of the pipeline onto the target plane 8 to obtain the three-dimensional trajectory line.

[0066] Step 104: Generate a first pipeline 3D model at the 3D target location based on the 3D trajectory line.

[0067] In some embodiments of this application, step 104 may specifically include the following steps:

[0068] Step b1: Obtain the cross-sectional information of the first pipe from the configuration information.

[0069] Step b2: Generate a cross-sectional pattern of the first pipe at one end of the three-dimensional trajectory line based on the cross-sectional information.

[0070] Step b3: Perform three-dimensional lofting processing on the cross-sectional shape according to the three-dimensional trajectory line to obtain the first pipeline three-dimensional model 10.

[0071] In some embodiments of this application, the configuration information further includes the first pipeline placement mileage, the number of pipelines placed, and the placement spacing; after step 104, the method may further include the following steps:

[0072] Based on the first pipeline 3D model 10, multiple first pipeline 3D models 10 are generated at corresponding positions in the target tunnel model 5 according to the first pipeline placement mileage, the number of placements, and the placement spacing.

[0073] Understandably, after generating one of the track-crossing pipe models, multiple corresponding track-crossing pipes can be generated in the target tunnel model 5 according to the first pipe placement mileage, number of pipes, and placement spacing.

[0074] In some embodiments of this application, such as Figure 4 As shown, when the first pipeline is a track-crossing pipe, multiple three-dimensional models 10 of the first pipeline are generated at the corresponding positions in the target tunnel model 5, including:

[0075] Step c1: Determine the target integrated cavern 7, and determine the centerline of the target integrated cavern 7 based on its location information.

[0076] The centerline is set perpendicular to the target tunnel model 5.

[0077] Understandably, the target integrated cavern 7 is used to house related equipment and the maintenance terminals for the four electrical lines. Therefore, it is necessary to determine the positions of multiple first pipeline 3D models 10 based on the location information of the target integrated cavern 7.

[0078] Step c2: Based on the first pipeline placement mileage, the number of placement pipes, and the placement spacing, generate multiple first overpass pipe models on one side of the centerline.

[0079] Each first track pipe model is connected to two cable trough 4 models inside the target tunnel model 5; the two cable trough 4 models are located on both sides of the internal space of the target tunnel model 5; the cable trough 4 model on the side closer to the target integrated cavern 7 is connected to the equipment model or maintenance end model inside the target integrated cavern 7.

[0080] Step c3: Based on the centerline, generate multiple second track tube models that are mirror images of the multiple first track tubes.

[0081] Step c4: Based on the plurality of first cross-rail pipe models and the plurality of second cross-rail pipe models, obtain the plurality of first pipe three-dimensional models 10.

[0082] In some embodiments of this application, the overhead rail pipes used for the pre-embedded power, communication, and signal cables during the construction of the tunnel's four-electric interface project; the pre-embedded trenches used for the contact network foundation in the tunnel; and the grounding terminals used for the integrated grounding in the tunnel, etc.

[0083] The steps for modeling the overhead contact line channel are as follows: Select the 2D tunnel element, identify the corresponding route name, and obtain the route model. Input the information of the overhead contact line channel to be placed, including: channel mileage, channel type, longitudinal spacing of channels, channel arc length, channel offset relative to the route in the cross section, channel height relative to the design rail surface, channel shape, and whether it is placed symmetrically in the cross section. The system integrates the information of each channel based on the input channel information. Obtain all secondary lining model elements within the mileage range of the channel to be placed, thereby obtaining the inner contour line information of the secondary lining at the channel placement location, and transforming it into a planar secondary lining inner contour line with the origin as the base point. When generating each channel model, based on the currently placed channel information and the inner contour line of the secondary lining, two trajectory lines are generated for the channel (if it is a straight channel, the origin (X=0, Y=0) is used as the starting point, and the channel length is extended in the positive X-axis direction to obtain the endpoint; a straight line is obtained through the obtained starting and ending points, and this straight line is used as the trajectory line of the straight channel). A channel cross-section is generated at the starting point of the trajectory line and extruded into a channel body model. Based on the channel trajectory line, and combined with the position and geometric information of the anchor bolts and flat steel in the channel information, anchor bolt and flat steel models are generated respectively. The generated channel, anchor bolt, and flat steel models are merged into a channel model. The channel model is moved to the corresponding position of the tunnel cross-section at the currently placed mileage by translation and rotation. Layers are set for the current channel model, codes are generated, component attributes are bound, and corresponding nodes are generated in the model structure tree window.

[0084] The modeling steps for grounding terminals are as follows: Create a new grounding terminal model library file. Starting from the insertion point of the grounding terminal, draw parametric components sequentially. The model size of each component can be adjusted through parameters, and the components can be linked (i.e., when the size or position of one component changes, the positions of other components in contact with it can be adjusted synchronously). Add the completed grounding terminal library file to the component library. Select the route model, the placement starting point, and the grounding terminal library file. Input the placement information (placement horizontal spacing, height difference, placement direction, placement spacing, placement quantity, etc.). The system calculates the coordinates of the insertion point based on the route model. Copy a grounding terminal model from the selected grounding terminal library file and place it at the insertion point with the origin as the base point. Rotate the grounding terminal around the Z-axis so that the normal vector of its cross-section is aligned with the tangent vector direction of the horizontal curve of the route at that position. Set a layer, generate a code, and bind component attributes for each grounding terminal model. At the same time, generate the corresponding node in the model structure tree window.

[0085] The method for generating a tunnel electrical, signaling, and communication (Electrical, Electrical, and Communication) pre-embedded pipeline model according to the embodiments of this application involves, in response to receiving an instruction to generate a first pipeline model, acquiring a target tunnel model and a pre-drawn two-dimensional trajectory line of the first pipeline; acquiring configuration information of the first pipeline model, including a first positional relationship between the first pipeline model and the target tunnel model, and a first included angle between the first pipeline and the target tunnel model; generating a three-dimensional trajectory line of the first pipeline at a three-dimensional target position in the target tunnel model based on the two-dimensional trajectory line of the track pipe, the first positional relationship, and the first included angle; and generating a three-dimensional model of the first pipeline at the three-dimensional target position based on the three-dimensional trajectory line.
