DETAILED DESCRIPTION

[0011] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0012] Example 1 See also Figure 1 Embodiment 1 provides a method for drawing a route map of a vehicle segment based on CAD, comprising the following steps: S101 Scheme Setting: Enter the design scheme and constraints based on the basic data. Figure 5 , which is the input interface of design scheme and constraints.

[0013] S102 Drawing the throat area: Enter or not enter (use the default value) the control parameters for drawing the throat area, automatically insert the turnout component at the specified position according to the control parameters and / or design scheme of the throat area, and automatically draw the throat area according to the mouse operation, the control parameters and / or constraints of the throat area.

[0014] S103 draws the car block outside the garage: input or not input (use the default value) the control parameters of drawing the car block, and automatically inserts the car block component at the specified position according to the control parameters of the car block or the design scheme.

[0015] Pre-built turnout and car stop assemblies, see Figure 2-3 , to construct the relevant parameters of the turnout component and the car stop component. Pre-enter the basic information of the train, such as Figure 4 As shown, this is the interface for inputting basic information of the train.

[0016] Among them, the basic information of the train includes the type of train, train formation, middle car length, head car length, train width and total length of the train. The turnout components include turnout type, turnout model, turnout angle, turnout AB value and track model. The car stop component includes car stop type and car stop model. The design plan includes the type of train, turnout model, whether it is automatic driving and whether it is covered. Among them, the control parameters of the throat area include turnout control parameters and curve radius (default values ​​can be used), etc. The turnout control parameters include turnout type, turnout direction, turnout model, turnout center coordinates and terminal direction, etc. The turnout center coordinates and terminal direction can be manually entered or determined by the mouse.

[0017] Among them, step S102 includes drawing turnouts, curves and tracks, etc.: automatically drawing turnouts by inserting turnouts, moving turnouts and / or copying turnouts. When inserting a turnout, select a track or an in-and-out line, and automatically insert the turnout component at the specified position according to the turnout control parameters and / or design scheme; when moving a turnout, the straight line and curve behind the turnout follow the movement; when copying a turnout, the turnout and straight line associated with the turnout follow the copy; when moving or copying a turnout, it is necessary to select the turnout and determine the turnout center coordinates and the end point direction. See Figure 6 When inserting a turnout, perform the following operations in sequence: 1 Select the turnout type, 2 Select the turnout direction, 3 Select the turnout model, 4 Select the turnout center coordinates and 5 Select the end point direction.

[0018] The curve is automatically drawn by automatically generating curves, moving curves and / or copying curves; when automatically generating curves, select the turnout branches and tracks, and automatically draw the curve according to the curve radius; when moving the curve, the straight line after the curve and the connected turnouts follow the movement; when copying the curve, the straight line and turnouts connected to the curve follow the copy; after the copied curve is positioned, if the straight line after the curve intersects with other straight lines, the turnout type is determined based on the angle of intersection, and then the corresponding turnout component is automatically inserted; when moving the curve, it is necessary to select the curve and enter or use the mouse to determine the new curve endpoint coordinates and moving direction; when copying the curve, it is necessary to select the curve and enter or use the mouse to determine the warehouse track and the new curve endpoint coordinates.

[0019] Automatically draw tracks by inserting tracks and / or copying tracks.

[0020] Specifically, the drawing process of the throat area is as follows: Insert turnout: Click "Insert Turnout" under the "Throat Area Plan Design" menu to insert a turnout in a blank or straight line. Fig.10 , Operation steps: Insert turnout type: Determine the type of turnout to be inserted according to the input command (single turnout (left or right), double turnout, crossing turnout, three-way turnout, crossover). Select the turnout center and the direction of the B end of the straight path. (If it is a crossover, you need to select 2 points and the direction of a turnout). Note: When inserting a turnout, the turnout type set by the turnout component is inserted by default. If you need to change the model of the inserted turnout, you can enter the turnout model when the shortcut command selects the turnout model when inserting the turnout. The next time you insert a turnout, if the type and model are the same as the last time you inserted the turnout, you can click the space bar when entering the shortcut command to repeat the last turnout by default.

[0021] Delete turnout: Click "Delete Turnout" under the "Throat Area Plan Design" menu, and select the delete turnout command. There are two types of delete turnout commands. One is to directly delete the turnout and the line behind the turnout; the other is to delete the turnout and the line behind one of the turnouts. Note: To delete the turnout, select the L24 turnout. You can choose to delete L24 (delete both B ends) or delete the B end behind L24 (select one B end to delete). When you select a B end to delete, the L24 turnout is still there. If you choose to delete L24, then the L24 turnout and the line behind the turnout will be deleted.

[0022] Copy Turnout: Click "Copy Turnout" under the "Throat Area Plan Design" menu, see Fig.11 , drag the turnout to the specified position. After copying the turnout, the straight lines and curves connected to the turnout will be copied together. Instructions: 1. After copying turnout A, drag it to the specified position B.

[0023] Move the turnout: Click "Move Turnout" under the "Throat Area Plan Design" menu and drag it to the specified position. After moving the turnout, the straight lines and curves connected to the turnout, as well as the corresponding text and marks, need to be moved in conjunction. Note: For case 1, refer to Fig.12 If you want to prevent the curve from entering the warehouse, or if you want the curve to be closer to the warehouse, you need to move the turnout forward or backward. After moving the turnout, the straight line and the curve will be linked together, and the corresponding straight line length, curve corner mark, etc. need to be linked together. At the same time, when moving the turnout, you also need to determine whether the conditions set during drawing are met. Case 2, see Fig.13 , there are other switches behind the moving switch, so when the switch is moved, the switch connected to the B end of the switch must also move with it.

[0024] Curve connection: Click "Curve connection" under the "Throat area graphic design" menu, see Fig.14 , select two endpoints according to the prompts to generate a curve. When connecting curves, the curve radius in the default parameter settings is used, but the curve radius can also be modified.

[0025] Modify curve: Click "Modify Curve" under the "Throat Area Plane Design" menu, select the curve according to the prompt, and modify the curve radius in the curve property dialog box on the right. Note: After modifying the curve radius, the corresponding curve connection straight line and superscript position also need to be adjusted accordingly. After modifying the curve radius, the curve radius that was modified last time will be used as the default when drawing the curve next time.

[0026] Move Curve: Click "Move Curve" under the "Throat Area Plan Design" menu, see Fig.15, select the curve according to the prompt, and drag it to the specified position. After moving the curve, the straight line and turnout connected to the curve, as well as the corresponding text and marks need to be moved in conjunction. Note: The curve has entered the warehouse, and you don't want the curve to enter the warehouse, or you want the curve to be closer to the warehouse, then you need to move the curve forward or backward. After moving the curve, the straight line and turnout will be linked together, and the corresponding straight line length, curve corner mark, etc., need to be linked together. When moving a curve, you also need to determine whether the conditions set when drawing are met.

[0027] Copy curve: Click "Copy Curve" under the "Throat Area Graphic Design" menu, see Fig.16 , select the curve according to the prompt, and drag the curve to the specified position. After copying the curve, the clamping line and turnout connected to the curve will be copied together. Description: Copy the curve, then move it to the upper track, select the straight line where the turnout center is located, and automatically generate the turnout and clamping line through the command.

[0028] Among them, the control parameters of the car block include car block type, car block model and remarks, etc. The drawing process is: select the car block model and enter the car block position.

[0029] Among them, the constraints include design parameter constraints and boundary constraints. The design parameter constraints include the minimum circular curve length, the minimum circular curve radius, the minimum straight line length between adjacent curves, the minimum straight line length for inserting short rails between turnouts, the minimum distance between turnouts and horizontal curve ends, the minimum distance between turnouts and vertical curve ends, the minimum line spacing between straight lines, the minimum line spacing between curves, and whether the curve is stored (non-entered value).

[0030] Furthermore, the design parameter constraints include general conditions and difficult conditions. When the design parameter constraints are not met, the components that do not meet the general conditions or difficult conditions are displayed in a specific color (such as yellow for components that do not meet the general conditions, and red for components that do not meet the difficult conditions). The components include turnouts, curves, car stops, and tracks. During the drawing process, if the design parameter constraints are not met, an error pop-up window will be displayed. Figure 7 As shown, the error pop-up window displays the name and value of the unsatisfied design parameter constraint, the current value, and the start and end point coordinates.

[0031] Boundary constraints include turnout model, range before and after the turnout, inner limit of the turnout, other areas inside the turnout, area range in front of the turnout, outer limit of the turnout and other areas outside the turnout. Boundary lines are automatically drawn along the track with boundary constraints, and columns and tracks are not allowed to be drawn within the boundary lines.

[0032] Accordingly, the method of the present invention further comprises: Design check: After drawing, manually select the inspection area to determine whether the components in the inspection area meet the constraints. If not, a pop-up window will be displayed. Figure 8 As shown, the pop-up window displays the error description and location coordinates. The specific process is as follows: Click "Design Check" under the "Throat Area Plan Design" menu to perform a design check. After the throat area plan design is completed, the "Design Check" function can be used to check whether the line design exceeds the specification limit or does not meet the specification requirements. When the check is wrong, the system command line lists the reasons for the error one by one so that modifications can be made. For example, "The length of the fourth circular curve does not meet the conditions!" The following items should be checked during the design inspection: minimum circular curve length, minimum circular curve radius, minimum straight line length between adjacent curves, minimum straight line for inserting short rails between turnouts, minimum distance between turnouts and the end of horizontal curves, minimum line spacing, curves cannot be stored, etc. The curve is not put into the warehouse as a reminder standard, not as a standard for not being able to draw the graph. (Because under some extreme conditions, it is allowed to be put into the warehouse.) When designing and checking, it is still necessary to do the inspection of the warehouse. Under difficult conditions, it is a feasible value, and under general conditions, it is a warning judgment.

[0033] Furthermore, the method of the present invention further comprises: Text annotation: Get the text annotation editing page, set the annotation control parameters, and automatically annotate all switches, curves, car stops and tracks according to the annotation control parameters. Fig. 9 As shown, the control parameters of the annotation include prefix, starting point number, numbering step and text height.

[0034] Furthermore, the method of the present invention further comprises: Draw a table: Get the table drawing editing page, set the control parameters for drawing the table, and automatically draw the table at the specified location according to the control parameters for drawing the table. Fig.17 As shown, the control parameters for drawing a table include table names and table fields, etc. The table names include line end coordinate table, curve information table, track table, turnout table and turnout coordinate table, etc. The table fields include intersection number, turning angle, curve radius, transition curve, tangent length, curve length, intersection coordinate X and intersection coordinate Y, etc. The specific process is as follows: After the map design is completed, click "Generate Table" under the "Throat Area Plane Design" menu to pop up the table setting page, where you can select the generated table and the fields in the generated table. Five tables need to be generated: 1) Line end point coordinate table; 2) Line plane elements and control intersection coordinate table. 3) Track table; 4) Turnout coordinate positioning table; 5) Turnout table. After the table is generated, the table can be moved. The table name can be modified. Table name: Displays all table names. Table fields: Display the header fields of the table settings based on the selected table. Table style: Draw a table diagram based on the selected table fields. Table settings: Set the row height and column width of the table. Add: Click the plus button to add a row. Edit: You can edit the data directly in the row. Delete: You can select a row to delete. Draw: Click Draw to generate a table in the icon. Cancel: Close the results drawing interface. Export: Check the table and click Export. Export the table to excel. Instructions: In the table name, the table data displayed comes from the table pre-configured in the data dictionary. The table fields are linked to display according to the selected table. The table fields are also configured in the data dictionary under the table name. Before operating the export function, you need to select the table to be exported in the table name. Before selecting the table field to set the table style, select the table name in the table name. The coordinates XY in the generated table are taken from the world coordinates, and the world XY and the real XY coordinates are opposite. For example, for the fork center, the world coordinates X=1.2, Y=3.5. Then after taking it into the table, X=3.5;Y=1.2.

[0035] Furthermore, the method of the present invention further comprises: Draw a frame: Get the frame drawing editing page, set the control parameters for drawing the frame, and automatically draw the frame at the specified position according to the control parameters for drawing the frame. The control parameters for drawing the frame include frame type, frame length, frame width, etc. The specific process is as follows: After the design is completed, click "Generate Drawing Frame" under the "Throat Area Plan Design" menu, click the mouse to select the drawing frame position in the upper left corner of the drawing, and the generated drawing frame page will automatically appear. The "Generate Drawing Frame" page sets the main technical parameters of the drawing frame. It has the same function as the drawing width and length settings in the parameter settings. Description: Drawing frame type: Select the drawing frame type: A0 / A1 / A2 / A3 / A4. Drawing frame length: Display the drawing length according to the selected drawing frame type. Designers can also edit it by themselves. Drawing width: Display the drawing width according to the selected drawing frame type. Designers can also edit it by themselves. The outer frame size of the generated drawing frame is displayed according to the set drawing frame length and width. The size of the inner frame of the drawing frame needs to be calculated. The spacing between the inner and outer frames of the frame is as follows: As shown in the screenshot, the spacing between the top and bottom and the right is fixed to 10m, and the spacing on the left is fixed to 25m. The default display of the drawing width is: 420; the default of the drawing length is 594. The commonly used drawing width is 297 / 420 / 594 / 841, and the corresponding default item for the length is 420 / 594 / 841 / 1189. The width and length of the image can be customized by the user.

[0036] The operation process of this method in the CAD program is as follows: after starting CAD, the corresponding display interface is called through the form module, the corresponding information is written back to the sqlite database through the Common module, and then the relevant functions in the plugin module are called to perform drawing operations.

[0037] In the prior art, the drawing process is: consulting the specification, clarifying the basic configuration, manual drawing and manual review, which is estimated to take 4 hours; in this patent, the drawing process is: setting the design plan and various control parameters, automatic drawing and computer review, which is estimated to take 1 hour. It can reduce drawing errors and save 75% of time.

[0038] Example 2 Embodiment 2 provides a CAD-based vehicle segment route map drawing device, comprising: The preset module is used to pre-build the turnout components and the car stop components and pre-enter the basic information of the train.

[0039] The editing module is used to enter design plans and constraints based on basic data.
