Step 100: generating conveyor longitudinal section line data and a conveyor longitudinal section line CAD graph in weft-wise software according to the topographic map; the conveyor is a long-distance belt conveyor with horizontal turns.
This step 100 specifically includes:
step 101: an initial plan view of the conveyor line is generated in weft software, and the specific operation is as follows:
first, a project is newly built in weft software, then a conveyor line is designed by using a main line plane design function, and an initial plane diagram of the conveyor line is generated. The method comprises the steps of performing inventory operation on intersection point coordinate data (suffix is "JD") generated in a ' main line plane design ' to obtain plane data of a conveyor line, running a ' design guide ' function after performing the ' main line plane design ' function, and calculating and drawing ' at a midpoint of the ' main line plane design ' function to obtain an initial plane diagram of the conveyor line.
Step 102: in the weft-wise software, the topography is converted into a digital-to-analog file using a "three-dimensional data read-in" function. Wherein, set up the topography line as the constraint line during the conversion, the elevation point sets up as the topography point.
Step 103: in weft software, according to the digital-analog file, a vertical section interpolation function, a vertical section fitting function and a vertical section design function are sequentially carried out on the initial plane diagram of the conveyor line, and a CAD diagram of the conveyor vertical section line with a ground line, a slope-changing point line and a design line is generated. The design line is a conveyor longitudinal section line.
In FIG. 2, the solid line with the line width of 0.4mm is the ground line generated by vertical section interpolation, the solid line with the line width of 0.3mm is the slope-changing point line generated by vertical section fitting, the solid line with the default line width is the design line automatically calculated by latitude ground software, and the mileage stake mark is arranged below the figure. Wherein, the gradient/% "of the vertical section fitting should be less than or equal to 32%.
Step 104: and carrying out slope pulling operation on the design line by utilizing a function of 'longitudinal section design', generating conveyor longitudinal section line data, and adjusting a conveyor longitudinal section line CAD graph according to the design line after the slope pulling operation to obtain a final conveyor longitudinal section line CAD graph, wherein the specific operation is as follows:
and (3) manually pulling a slope of the design line generated by the vertical section fitting function in the step 103 by utilizing the vertical section design function, and setting convex-concave arc radius to adjust the design line until the conveyor vertical section line by adding and deleting slope changing points.
Storing a vertical section line data file (suffix is ZDM) generated by manual slope pulling, and storing an adjusted conveyor vertical section line CAD graph; the manual slope pulling is to change the road line automatically calculated in weft into a conveyor longitudinal section line meeting the standard through adding and deleting slope changing points.
Step 200: and performing primary discretization processing on the conveyor vertical section line CAD graph by using CAD software to obtain the conveyor vertical section line CAD graph with the equal division point marks, namely performing equidistant equal division on a solid line segment or an inclined line segment with a default line width in the horizontal direction of 20 meters in the figure 2, wherein the concave-convex arc segment is equally divided into arc segments with the length of 20 meters, and reserving equal division points and storing the primary discretized CAD graph.
Step 300: and performing secondary discretization processing on the conveyor vertical section line CAD graph with the equal division point marks by using weft-wise software and the conveyor vertical section line data to obtain a conveyor vertical section line CAD graph after secondary discretization, namely inserting a variable slope point in the conveyor vertical section line data to an equal division point in the CAD graph after primary discretization by using an inserting variable slope point function in vertical section design in weft-wise software, storing the conveyor vertical section line data (suffix is 'ZDM') after secondary discretization, and storing the conveyor vertical section line CAD graph after secondary discretization and the storage items.
Step 400: in weft-wise software, the CAD graph of the conveyor longitudinal section line after secondary discretization is processed to obtain a final plane graph and a final elevation graph of the conveyor line, and the method comprises the following specific operations:
step 401: and processing the CAD graph of the longitudinal section line of the conveyor after the secondary discretization by utilizing the function of outputting a vertical curve table in a table module in weft-ground software to obtain a first vertical curve table.
Step 402: and (3) extracting and integrating pile number data from the first vertical curve table derived in the step 401.
Examples pile number data "k1+240.844" is sorted to "1240.844".
Step 403: and (3) finding and opening a file with a suffix of 'STA' in the project file in the background folder, replacing the pile number data extracted in the step (402) with the data with a column name of 'HINTCAD 5.84_STA_SHUJU' in the file, and storing in a 'STA' format.
Step 404: the file with the new "STA" suffix obtained in step 403 is imported into the weft-ground software through the "project manager" of the weft-ground software, and the project is saved.
Step 405: the "side stake interpolation" function of the latitude software is used for processing the new "STA" suffix file to generate a "TXT" file, and the "TXT" file contains landing leg (slope changing point) coordinate information, stake number information and land line elevation.
Step 406: and (3) deriving a template with a suffix of JDW from an intersection point coordinate import/export function in a data module in the latitude software, importing leg (slope change point) coordinate data in a file with the suffix of TXT obtained in step 405 into the template of JDW, storing, and importing the leg into the latitude software to generate an intersection point coordinate file with the suffix of JD by using the intersection point coordinate import/export function.
Step 407: the intersection coordinate file obtained in step 406 is imported into the "project manager" in the latitude software. And a final conveyor line plan is derived from weft-wise software 'main line plane design', and a final conveyor line elevation is derived from 'longitudinal section design', and the coordinates of the intersection point of the main line plane and the landing leg (slope changing point) of the elevation can be found to be corresponding through comparison of the two images.
