Description

Technical Field

[0001] This invention belongs to the field of design technology for flexible overhead contact lines for rail transit, and more specifically, relates to a drawing method and system for flexible overhead contact lines for rail transit. Background Technology

[0002] The design of flexible overhead contact lines for rail transit involves a significant amount of daily calculation and drafting work, requiring the extraction and analysis of specific data based on business needs. The main requirements for designing flexible overhead contact lines for rail transit include: geometric drawing requirements, where designers need to create numerous repetitive and fixed graphic units, including columns, anchor sections, and overhead ground wires, and label them with corresponding information. Due to limitations imposed by factors such as track curves and civil engineering conditions, the installation methods of overhead contact lines are flexible and varied, requiring designers to customize the flexible overhead contact line design according to specific requirements; and rapid modification requirements, where designers need to modify already drawn elements during the drafting process. This is because many repetitive elements such as columns and anchor sections are present on the track... The relative intervals on the overhead contact line must remain fixed, and designers need to be able to quickly draw the elements that need to be modified and subsequent elements. There is a requirement for unified numbering; after drawing elements such as columns and anchor sections, designers need to number each identical element according to a unified format. There are also requirements for installation drawing numbers, anchor section lengths, and equipment and material statistics; after completing the plan layout, designers need to create statistical tables such as installation drawing number tables, anchor section length tables, and main equipment and material tables on the drawings, and generate corresponding Excel statistical tables. Finally, there are requirements for drawing layout; after completing all drawings, designers need to arrange the drawings according to specifications, including all details. To meet these requirements, sophisticated automatic drawing software needs to be designed. Given input parameters, this software should automatically draw the overhead contact line and automatically modify the drawings after parameter adjustments, thereby reducing the time spent on repetitive drawing and improving drawing efficiency and quality.

[0003] Currently, the design and drawing of flexible overhead contact lines for rail transit are mostly done manually. Individual elements are drawn manually, and subsequent elements are drawn sequentially based on calculations. When modifying the position of intermediate elements, the positions of subsequent elements are also modified manually in sequence. There is no automated drawing software to assist in the drawing process. Summary of the Invention

[0004] To address the above technical problems, this invention proposes a method for drawing flexible overhead contact lines for rail transit, comprising:

[0005] Step 101: Identify the route drawing and store the route information as the drawing reference.

[0006] Step 102: Import the fixed-format line curve feature table, installation drawing number table, long and short chain table, and pull-out value table as input data;

[0007] Step 103: Draw the columns according to the input data, and set the starting point for the layout by selecting the route or specifying the starting mileage. After setting the column interval, draw them in pairs, draw them individually, or draw them in batches with a specified number of columns, and calculate the pull-out value.

[0008] Step 104: Specify the drawing route, select the drawing direction, and automatically drag out the value by clicking on the column;

[0009] Step 105: Select the drawing direction, draw the overhead ground wire and auxiliary feeder, and set the anchor type. By selecting the column, draw the anchor segment joint, set the custom anchor segment number, and select the equipment type, quickly draw the equipment at the specified location.

[0010] Furthermore, step 101 also includes: merging multiple line segments into a complete line by specifying the starting and ending line segments of multiple line segments that are connected end to end to form the line, and storing the starting and ending points of the complete line, as well as whether the line belongs to the left or right line.

[0011] When merging lines, merge them by specified layers or colors, or display all line segments involved in the merge for selection, to avoid the inability to determine which line the designer needs to edit when lines branch off.

[0012] Furthermore, between steps 101 and 102, the following is also included: setting the line code, anchor segment code, and installation drawing number code for automatically drawing the table.

[0013] Furthermore, step 103 also includes: modifying the column by specifying the column number or selecting the column, which can be modified in pairs.

[0014] Furthermore, step 106 is included: by importing data and drawing content, automatically generating an installation drawing number table, an installation drawing number statistics table, an anchor section length statistics table, and a main equipment and material statistics table on the drawings, and exporting them as Excel spreadsheets.

[0015] This invention also proposes a mapping system for flexible overhead contact lines in rail transit, comprising:

[0016] The identification module is used to identify the circuit diagram and store the circuit information as a drawing reference.

[0017] The import module is used to import fixed-format line curve characteristic tables, installation drawing number tables, long and short linked lists, and pull-out value tables as input data.

[0018] The column drawing module is used to draw columns according to the input data, and to set the starting point for the layout by selecting the route or specifying the starting mileage. After setting the column interval, it can draw columns in pairs, draw columns individually, or draw columns in batches according to a specified number, and calculate the pull-out value.

[0019] The annotation module is used to specify the drawing route. After selecting the drawing direction, the value is automatically drawn by clicking on the column.

[0020] The drawing module is used to select the drawing direction, draw overhead ground wires and auxiliary feeders, set the anchor type, draw anchor segment joints by selecting columns, set custom anchor segment numbers, and quickly draw equipment at specified locations after selecting equipment types.

[0021] Furthermore, the identification module also includes: merging multiple line segments into a complete line by specifying the starting and ending line segments of multiple line segments that are connected end to end to form the line, and storing the starting and ending points of the complete line, as well as whether the line belongs to the left or right line.

[0022] When merging lines, merge them by specified layers or colors, or display all line segments involved in the merge for selection, to avoid the inability to determine which line the designer needs to edit when lines branch off.

[0023] Furthermore, the identification module and the import module also include: setting the line code, anchor segment code, and installation drawing number code for automatically drawing tables.

[0024] Furthermore, the column drawing module also includes the ability to modify columns by specifying their numbers or selecting them, and the ability to modify them in pairs.

[0025] Furthermore, it also includes a table export module, which can automatically generate an installation drawing number table, an installation drawing number statistics table, an anchor section length statistics table, and a major equipment and material statistics table on the drawings by importing data and drawing content, and export them as Excel spreadsheets.

[0026] In summary, the technical solutions conceived by this invention have the following beneficial effects compared with the prior art:

[0027] The automatic drawing method and system for parametric flexible overhead contact lines in rail transit, as described in this invention, utilizes professional drawing software to automate the drawing process. It automatically performs data calculations and executes automatic drawing based on requirements. Simultaneously, it generates Excel spreadsheets of the calculated and drawn data, reducing repetitive work for designers and significantly improving their efficiency. Based on professional drawing software, the automatic drawing system for parametric flexible overhead contact lines in rail transit can automatically draw the contact lines according to input data and option settings, avoiding the tedious process of manually drawing the same elements, saving time and costs. It also avoids the cumbersome adjustment and operation processes of traditional methods, improving drawing efficiency. Furthermore, the system standardizes the drawing format, regulating equipment elements and annotation formats, ensuring that drawings from different designers are in the same format, facilitating reading and understanding by downstream designers and construction personnel. Compared with traditional drawing methods, this invention can unify the three traditional drawing steps of drawing elements, drawing tables, and arranging drawings, realizing the automation of drawing flexible overhead contact networks for rail transit and greatly improving the efficiency of power supply drawings.
