[0001] The present invention relates to the technical field of rail transit tunnel line design, and in particular to a method and system for automatic design of rail transit lines and section planes. Background Art

[0002] At present, when designing lines and sections, designers in the rail transit industry need to manually measure and determine the mileage and coordinates of the starting and ending points of the interval in the AutoCAD line and section plan design plan file, manually draw the interval plane contour according to the structure size of the interval, and draw the plane markings of the mileage of the starting and ending points of the interval, the plane markings of the coordinates of the starting and ending points of the interval, and the plane markings of the stations one by one. Finally, draw the plane contours and markings of the connecting channels and wastewater pump rooms, and the plane contours and markings of the control points of the intervals, and manually adjust the formats of various AutoCAD graphics elements to meet the professional engineering design drawing standards for rail transit lines and sections.

[0003] The above work involves many manual operations such as drawing auxiliary lines, selecting objects, measuring lengths, editing texts, and adjusting styles, which are time-consuming and inefficient. Therefore, it is urgent to improve the production method and use AutoCAD software for secondary development to convert a large amount of repetitive work from manual to computer-automated work, thereby improving production efficiency.

[0142] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0143] The preferred embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0144] Embodiment 1:

[0145] The present invention provides a method for automatic design of rail transit lines and sections. Figure 1 The method for automatic design of rail transit lines and section planes comprises the following steps:

[0146] According to a first aspect of an embodiment of the present invention, a method for automatic design of rail transit lines and sections is proposed, the method comprising:

[0147] S1: Open the circuit plan design file, automatically read and store the circuit design data.

[0148] Specifically, the data reading can be directly read in the line plan dwg, dws, dwt, dxf format files by writing an AutoCAD secondary development program. The line design plan data refers to the line plan design plan data, including but not limited to line plan intersection data, station names and mileage data.

[0149] S2: Obtain and store the interval communication channel and wastewater pump room data, interval control point data, interval mileage range, construction method, and structural dimensions.

[0150] Specifically, the interval communication channel and wastewater pump room data include the setting form of the interval communication channel and wastewater pump room, and the line mileage corresponding to the center line of the interval communication channel and wastewater pump room. The interval control point data include the name of the interval control point, the coordinates of the vertex of the plane contour of the interval control point, the bottom elevation of the interval control point foundation, and the text description of the interval control point foundation. The interval mileage range refers to the line mileage corresponding to the starting point of the interval to the line mileage corresponding to the end point of the interval. The construction methods include but are not limited to shield, open excavation, elevated, and roadbed. The structural size is the horizontal projection distance from the center line of the interval line to the outermost side of the interval structure. The above interval parameters are saved in tabular form, see Figure 2 .

[0151] S3: Create polylines based on interval structure dimension offsets and automatically draw interval plane outlines.

[0152] Furthermore, the specific steps of step S3 are as follows:

[0153] S3.1: Draw the interval plane contour polylines PL1, PL2, PL3, PL4.

[0154] Specifically, the PL1, PL2, PL3, and PL4 are respectively obtained by offsetting the center line of the right line and the center line of the left line of the line within the interval mileage range to both sides, wherein PL1 is obtained by offsetting the center line of the right line of the line within the interval mileage range to the outside, that is, away from the left line side, PL2 is obtained by offsetting the center line of the right line of the line within the interval mileage range to the inside, that is, close to the left line side, PL3 is obtained by offsetting the center line of the left line of the line within the interval mileage range to the inside, that is, close to the right line side, and PL4 is obtained by offsetting the center line of the left line of the line within the interval mileage range to the outside, that is, away from the right line side; see Figure 3 , Figure 4 The offset is the structural size described in step S2. Specifically, the offset can use the OFFSET offset command in AutoCAD to directly implement the copying and offset of the polyline.

[0155] Specifically, when the interval construction method in step S2 is open cut or elevated, only the outermost contour polylines PL1 and PL4 of the interval plane need to be drawn. When the interval construction method in step S2 is roadbed, there is no need to draw the interval plane contour polylines in this step.

[0156] S3.2: Adjust the polyline format described in step S3.1.

[0157] Specifically, the format adjustment includes but is not limited to the adjustment of color, line type, and line width to meet the professional engineering design drawing standards for rail transit lines and sections. Figure 5 .

[0158] S4: Calculate the vertex coordinates of the interval mileage annotation, create polylines and mileage annotation text, and automatically draw the interval start mileage plane annotation and the interval end mileage plane annotation. Figure 3 , Figure 4 .

[0159] Furthermore, the specific steps of step S4 are as follows:

[0160] S4.1: Define the starting and ending points P1, P2, P3, and P4 of the interval plane on the right line and the left line of the line.

[0161] Specifically, the coordinates of the points P1, P2, P3, and P4 are determined according to the starting and ending mileages of the interval in step S2.
