Detailed Description
The method of the present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 1, the automatic generation method of the railway engineering construction organization image progress chart comprises the following three steps:
s1, designing a geometric primitive drawing interface. The railway engineering construction organization image progress chart consists of different geometric primitives, so that different geometric primitives are designed to be expressed according to the drawing requirements of the plan items. The invention designs three basic geometrical primitive bottom drawing interfaces of point, line and surface respectively, and designs a color interface for distinguishing different types of working points for each geometrical primitive. The geometry and applicability of the geometric primitives are shown in Table 1:
TABLE 1
The method comprises the following steps:
(1) The point: the geometric forms of the system mainly comprise circular, square, star-shaped and other patterns, and are used for representing the positions and types of large temporary facilities, such as mileage positions of beam manufacturing fields and track slab fields;
(2) A wire: the geometric form is mainly divided into three types of vertical lines, upward oblique lines and downward oblique lines. The vertical lines are used for representing construction plans of strip-shaped construction activities, such as construction plans of continuous beams (No. 0 blocks, folding sections and other paragraphs), and the oblique lines are used for representing plan items with certain construction directions, such as construction plans of frame beams, rail laying and surrounding rocks. Since the horizontal axis represents mileage and the vertical axis represents time in the visual progress chart, the construction directions expressed by oblique lines in different directions are different: the upward slope represents the construction from the small mileage to the large mileage, and the downward slope represents the construction from the large mileage to the small mileage. Construction plans for different types of worksites may be distinguished by line type (e.g., straight line, broken line, dot-dash line, etc.) and color.
(3) And (3) surface: the plan items with unobvious construction directivity and a certain mileage range are expressed by faces. The surface is mainly square, and is commonly used for representing the construction plans of roadbeds, tunnels and bridges. Construction plans for different types of worksites may be distinguished by fill patterns (e.g., no fill, grid fill, cross line fill, etc.) and colors.
S2, designing a data storage interface and semantic association of the construction organization plan item and the drawing parameters. The invention designs a storage structure, an index field and an association relation of a plan item and drawing parameters, wherein the storage structure of the construction organization plan item comprises fields such as space constraint, time constraint, logic constraint and the like, tree-shaped hierarchical structure and attribute information are described in a two-dimensional table form, and the drawing parameter data table comprises information such as geometry, style, color and the like.
See the stored structure and semantic association diagram of construction organization plan items and drawing parameters shown in fig. 2. The data storage structure of the construction organization plan item comprises parameters such as an ID, a ParentID, a starting mileage, a stopping mileage, a starting date, a stopping date, a drawing level and the like, wherein the ID is an index field of the structure. The data storage structure of the plan items not only describes all construction plan items of the whole project, but also describes the logic relation among the plan items through IDs and ParentIDs, so that the node position (root node, logic node and leaf node) of a certain plan item in the whole project tree can be judged, and finally, the tree-shaped hierarchical structure and attribute information are described in the form of a two-dimensional table. The drawing parameters store ID, JHXID, geometry, drawing style, RGB color information of each plan item, wherein ID is an index field, and the JHXID field can be semantically associated with the ID field in the plan item data storage structure.
And S3, automatically generating an image progress chart. The construction organization plan item is traversed, corresponding drawing parameters are matched, corresponding geometric primitive drawing interfaces are called, drawing of each component module of the image progress chart is completed, the image progress chart comprises a key working point schematic diagram, a scale division, a major facility, a milestone and a construction image progress, and all sub-modules are spliced, so that automatic generation of the image progress chart can be completed.
Specifically, the automatic generation of the avatar progress chart includes three steps: the three steps are described in detail below, namely, drawing the overall frame of the image progress chart, drawing the construction image progress sub-module and drawing other sub-modules.
(1) Drawing an image progress chart overall frame:
the railway engineering construction organization image progress chart mainly comprises sub-modules of key working points, mark section division, large temporary facilities, construction image progress, milestones and the like. Before the image progress chart is generated, the overall frame needs to be drawn in advance according to the page layout style parameters. Since the X-axis direction represents mileage and the Y-axis represents time, the width of the overall frame can be calculated with the mileage range and the height can be calculated with the height of each sub-module, wherein the height of the construction image progress sub-module needs to be calculated with the period time. The calculation formulas of the width and the height of the integral frame are shown as formula (1), wherein the scaling factors can be used for scaling the dimension of the image progress chart in the X-axis direction and the Y-axis direction, so that the image is convenient to print.
Wherein W represents the width of the frame, W represents the width of the cell occupied by the character marks on two sides of the frame, and m e Represents the termination mileage, m s Represent the initial mileage s x Represents the scaling factor in the X-axis direction, H represents the height of the frame, H 1 ～H 4 Respectively representing the heights of sub-modules such as key working points, scale segment division, major facilities, milestones and the like, T e Representing the final end time of the whole project, T s Representing the start time of the entire item s y Representing the scaling factor in the Y-axis direction.
(2) Drawing construction image progress submodule
Fig. 3 shows a flow of generating a construction image progress sub-module, wherein the left side is used for judging whether the plan item needs to be drawn, and the right side is a way of drawing the plan item. As shown, first, each plan item in the engineering project table is traversed, and the drawing level of the current plan item is judged. If the drawing level is 1, it indicates that the plan item must be drawn; if the drawing level is 2, the plan item does not need to be drawn, and the next plan item is traversed at the moment; if the drawing level is 0, whether the drawing is needed is judged according to the position of the node, if the node is a path node, the drawing is not needed, the next plan item is continuously traversed, and if the node is a leaf node, the plan item is needed to be drawn. When the plan item is drawn on the right side, the geometric parameters, the styles and the color parameters in the drawing parameter table are matched through the IDs, and then the plan item is drawn through calling a geometric primitive drawing interface.
The construction image progress sub-module displays the mileage range, the planned starting date and the planned ending date of each project item in a line form and a plane form. Before drawing lines and pictures, the vertexes of the lines and the faces are required to be positioned, the calculation formula of the vertex coordinates is shown in the formula (2) assuming that the lower left corner of the construction image progress sub-module is the origin, and if the lower left corner of the construction image progress sub-module is not the origin, the coordinates are correspondingly offset.
Wherein x is i Represents the abscissa of the ith point, m i Mileage indicating the i-th point, y i Represents the ordinate of the ith point, T i Indicating the time of the ith point.
(3) Drawing other sub-modules
In other sub-modules, the key work point sub-module is used for displaying the mileage range of the important work point in the project, and is mainly represented by drawing a rectangle, distinguishing the work point types by adding different colors, and describing the specific work point name in a annotation form.
The marking sub-module is represented by a straight line with arrows at two ends and is used for displaying the mileage range of each marking in the project.
The large temporary facility submodule is used for displaying mileage positions of large temporary facilities such as a girder manufacturing field, a track slab field, a track laying base and the like, and is mainly represented by dot symbols.
And the milestone sub-module is drawn into a pattern of a rule and is used for displaying the mileage information of the railway line, so that the mileage position of each working point in the planning item can be conveniently checked.
The legend is represented by symbols and text notations to illustrate the geometric symbols and colors used for each type of worksite.

Fig. 4 shows a visual progress chart drawn by reading different page layout parameters, wherein a marking sub-module is added in the visual progress chart at the upper right corner, the upper and lower positions of the milestone sub-module and the visual progress sub-module are opposite to the left side, and the visual progress chart at the lower side is scaled in the horizontal axis direction. Scaling the image progress chart on the horizontal axis and the vertical axis according to a certain proportion is beneficial to more convenient viewing when drawing and printing drawings.

Figure 5 shows an image progress chart of different railway engineering projects automatically generated using the method. The upper part is a XX railway construction organization image progress chart, and the lower part is a YY railway construction organization image progress chart, and although the page layout of the two is consistent, the detail content of each sub-module is different.
