s101, obtaining the effective height of a display picture frame of a railway line longitudinal section, the longitudinal upper limit of the display picture frame, the longitudinal lower limit of the display picture frame and the longitudinal center position of the display picture frame.
Specifically, various parameters of the map of the longitudinal section of the railway line can be set according to the popped up display panel, and the parameters of the map can comprise a railway line design result file, header item information, map height and map range.
The line design result file comprises key design elements such as a slope line, a ground line, notch information and plane information in a railway line longitudinal section diagram, wherein the notch information comprises a cut-off point notch such as a bridge, a tunnel or a station, the notch information corresponds to a boundary point of the railway line longitudinal section diagram needing page changing display, and the plane information can be the whole trend of a railway when the railway is overlooked. The header item information can be used for determining the height of a title bar in the railway line longitudinal section diagram, the height of the title bar influences the effective height and the central position of a display frame, and the height of the frame also influences the effective height and the central position of the display frame. If the mapping range is designated, calculating according to the designated mapping range, for example, the mapping range corresponds to the range from the point A to the point B; if no map scope is specified, the calculation is performed according to the whole scope in the result file by default, for example, the map scope corresponds to the scope from the C place to the D place, and the scope from the C place to the D place is a subset of the scope from the A place to the B place.
After the setting of each parameter of the longitudinal section chart of the railway line is finished, the staff gauge button can be clicked, the staff gauge information automatic calculation button is clicked in the popped up interface, and the automatic calculation process of the staff gauge information of the longitudinal section of the railway line provided by the embodiment of the disclosure is started.
The method comprises the steps of obtaining the effective height of a display picture frame of a longitudinal section of a railway line, obtaining the height of the picture frame, the height of a title bar and the upper and lower reserved height of the display picture frame, obtaining the total height of the display picture frame according to the height of the picture frame and the height of the title bar, and obtaining the effective height of the display picture frame according to the total height of the display picture frame and the upper and lower reserved height of the display picture.
Fig. 2 is a schematic diagram illustrating calculation of the vertical section size information of the railway line according to the embodiment of the present disclosure. As shown in fig. 2, the height d10 of the picture frame subtracts the height d20 of the title bar to obtain a total height d30 of the display frame, the total height d30 of the display frame subtracts the upper and lower reserved heights of the display frame to obtain an effective height d60 of the display frame, that is, the total height d30 of the display frame subtracts the upper reserved height d40 of the display frame and the lower reserved height d50 of the display frame to obtain an effective height d60 of the display frame, the height value to be reserved between the slope line and the display frame is the reserved height d50 of the lower part of the display frame, the height value to be reserved between the ground line and the display frame is the reserved height d40 of the upper part of the display frame, and the effective height d60 of the display frame is calculated by combining the upper and lower reserved heights of the display frame, so that the.
The method comprises the steps of obtaining a longitudinal upper limit of a display picture frame, a longitudinal lower limit of the display picture frame and a longitudinal central position of the display picture frame of a longitudinal section of a railway line, obtaining the longitudinal upper limit of the display picture frame according to a picture frame original point, a title bar height, a ruler height and a reserved height of the upper portion of the display picture frame, obtaining the longitudinal lower limit of the display picture frame according to the ruler original point and the reserved height of the lower portion of the display picture frame, and obtaining the longitudinal central position of the display picture frame according to the longitudinal.

The vertical coordinate of the scale origin B plus the reserved height d50 at the lower part of the display frame can obtain the lower vertical limit of the display frame, namely the minimum vertical coordinate. And the average value of the upper longitudinal limit of the display picture frame and the lower longitudinal limit of the display picture frame is the longitudinal center position of the display picture frame.
S102, defining a differential rectangular range of a ground line and a slope line in a display drawing frame of the railway line longitudinal section.
Fig. 3 is a schematic diagram illustrating a differential rectangle of a longitudinal section of a railway line according to an embodiment of the present disclosure. As shown in fig. 3, the ground line 11 and the gradient line 12 in the display frame of the longitudinal section of the railway line are defined in a differential rectangle range, and a connection line with four intersections of the ground line and the gradient line within a single step range from a start point to an end point of the gradient line may be used as one differential rectangle 13 based on the gradient line.
Specifically, the range of the ground line and the gradient line is represented by a rectangular frame with a certain width, specifically, the range of the ground line and the gradient line is represented by a rectangular frame with a certain step length value from a starting point to an end point of the gradient line by taking the gradient line as a reference, and the range of the ground line and the gradient line is represented by using the rectangular frame, wherein the rectangular frame is a maximum enclosing frame consisting of four intersection points with the ground line and the gradient line in a single step length range. It should be noted that this rectangular frame is used for comparison calculation only, and the drawing does not include this element.
When the distance between the ground line and the slope line at the same position is larger than or equal to a first set multiple of the effective height of the display picture frame, the longitudinal coordinate of the differential rectangle at the position is converted according to the product of the effective height of the display picture frame and the first set multiple and the longitudinal coordinate of the slope line at the position.
Illustratively, the first set multiple may be equal to 0.6, for example. As shown in fig. 3, when the distance between the ground line and the slope line exceeds 0.6 times of the effective height of the display frame at a certain position, the ground line is considered to need to be cut, and taking the position a in fig. 3 as an example, when the ground line is above the slope line and the distance between the ground line and the slope line is greater than or equal to 0.6 times of the effective height of the display frame, the longitudinal coordinate of the differential rectangle at the position is equal to the longitudinal coordinate of the slope line at the position plus 0.6 times of the effective height of the display frame. When the ground line is below the slope line and the distance between the ground line and the slope line is greater than or equal to 0.6 times of the effective height of the display frame, the longitudinal coordinate of the differential rectangle at the position is equal to the longitudinal coordinate of the slope line at the position minus 0.6 times of the effective height of the display frame.

As shown in fig. 4, the differential rectangles are grouped for the first time by merging according to the mean value of the central longitudinal coordinates of the adjacent differential rectangles, the maximum longitudinal coordinates of the adjacent differential rectangles, the minimum longitudinal coordinates of the adjacent differential rectangles and the effective height of the display frame, and when the difference between the mean value of the central longitudinal coordinates of the adjacent differential rectangles and the maximum longitudinal coordinates of the adjacent differential rectangles, and the difference between the mean value of the central longitudinal coordinates of the adjacent differential rectangles and the minimum longitudinal coordinates of the adjacent differential rectangles are all smaller than a second set multiple of the effective height of the display frame, the adjacent differential rectangles are divided into a group of differential rectangles.
For example, the second setting multiple may be equal to 0.5, as shown in fig. 4, when the differential rectangles are grouped for the first time, the current differential rectangle is compared with the next differential rectangle, and whether the two differential rectangles can be grouped is determined by whether the difference between the average value of the central longitudinal coordinates of each differential rectangle in the grouped group and the maximum longitudinal coordinate of the differential rectangle in the grouped group, and the difference between the average value of the central longitudinal coordinates of each differential rectangle in the grouped group and the minimum longitudinal coordinate of the differential rectangle in the grouped group are both smaller than 0.5 times of the effective height of the display frame, i.e. both smaller than half of the effective height of the display frame. If so, the next differential rectangle is classified into the group, otherwise, the grouping is performed again from the next differential rectangle frame, and after the differential rectangles are exemplarily arranged for preliminary grouping in fig. 4, the differential rectangles are divided into five groups, namely a1, a2, a3, a4 and a 5. In addition, the average value of the central longitudinal coordinates of the differential rectangles is used as the basis of the grouping of the initial combination, so that the drawing elements can be distributed in the middle of the drawing as many as possible.
