Fig. 1 is a flowchart of a coal pile graphical management method for a coal yard of a thermal power plant according to an embodiment of the present invention, which specifically includes:
and S100, receiving stacking data of each coal pile in the coal yard.
The stacking data of each coal pile received in this step includes position and layer height data of the coal pile, and specifically, the position and layer height data of each coal pile on the site are recorded by projecting the coal yard from a two-dimensional view perspective, or the position and layer height data of each coal pile on the plane are recorded by projecting the coal pile on the site onto a predetermined plane perpendicular to the coal yard floor, and the position of the coal pile can be represented by the position of the coal pile covering the coal yard floor in a two-dimensional view. For example, the start position, the end position, the distance from the position of the height change to the reference point in the two-dimensional view and the height of the coal seam can be directly measured as stacking data. In some embodiments, the coal yard is marked with a position mark on site, and the acquisition personnel can directly refer to the position mark to obtain the position data of the coal pile. For the coal pile height data, it can be obtained by roughly estimating or directly measuring the height of the coal pile, and in some embodiments, the height of the coal bed is preset into several levels, and the height of the coal pile is reflected by the number of layers.
And step S200, converting the stacking data into character codes.
In this step, corresponding character codes are generated according to the stacking data of the respective coal piles. The position and layer height data of the coal pile in the stacking data are corresponding to a predetermined two-dimensional coordinate system corresponding to a two-dimensional view of the coal yard site, so that the position and layer height data of the coal pile can be correspondingly embodied in coordinate values in the two-dimensional coordinate system. Based on the data conversion, and according to a preset coding rule, generating a corresponding character code, wherein the character code is suitable for generating a curve reflecting the coal pile outline in a two-dimensional coordinate system. In this embodiment, the contour curve of the coal pile in the two-dimensional coordinate system is composed of a plurality of continuous straight line segments, and the adopted character code rule is as follows:
1. the character code is composed of 30-bit characters in total, and each 3-bit character is a group of sections for being divided into 10 group sections;
2. when the first numeric area of the composition segment is (2, 0, 3, 4), the second and the third digits represent the abscissa value in the two-dimensional coordinate system, wherein the first numeric value is 2 to represent the rise, specifically, the outline extends upwards by taking the abscissa value represented by the second and the third digits as the starting point; the first digit is 3 to represent descending, specifically, the horizontal coordinate value represented by the second and third digits is taken as a starting point, and the contour line extends downwards; the first digit is 0 to represent that the upper extreme point is reached, specifically, the abscissa values represented by the second and the third digits are the highest points under the upward extending trend of the contour line, and the contour line does not extend upwards any more at the current abscissa position; the first digit is 4, the lower extreme point is reached, specifically, the abscissa values expressed by the second and third digits are the lowest points of the contour line under the downward extension trend, and the contour line does not extend downwards at the current abscissa position;
3. when the first bit value of the composition segment is 8, the second and third bits are also set to 8, and the composition segment 888 has no actual meaning and is only used for filling up 30-bit characters;
4. when the three-digit characters of the composition segment are all underlined, representing the extension of the contour line before continuing;
5. when two constituent segments with the first bit value ranges of (2, 0, 3 and 4) are directly adjacent or only the constituent segment 888 is arranged between the two constituent segments, the straight line segments corresponding to the two constituent segments are connected through a horizontally extending straight line segment.
And step S300, analyzing the coal pile in a graphical mode.
In this step, in response to a graphical request for a coal pile in a coal yard, a contour line representing the corresponding coal pile is generated on a visual two-dimensional coordinate system according to the corresponding character code, and the contour line is composed of a plurality of continuous straight line segments as described above.
In a visual two-dimensional coordinate system, a horizontal axis (horizontally extending) represents the ground of a coal yard, the width of the horizontal axis (vertically extending) represents the stackable area of the coal yard, scale marks are arranged according to scales on the horizontal axis and the vertical axis, namely, vertical lines which respectively pass through scale points on the horizontal axis and horizontal lines which respectively pass through scale points on the vertical axis are arranged, and the vertical lines and the horizontal lines define a plurality of cells which are equal in size and are arranged in an array. In this embodiment, the unit scales of the horizontal axis and the vertical axis displayed in the visualized two-dimensional coordinate system have the same length, so that the cell is square.
The graph analysis rule adopted in the embodiment is to limit the contour line representing the coal pile to extend only along the transverse side line and the diagonal line of each unit cell, that is, the ascending or descending slope of the side wall of the coal pile represents the contour of the coal pile through the diagonal line arranged in the unit cell, as described above, the unit cell is square in the embodiment, so that the coal pile is displayed to ascend or descend along an angle of 45 degrees in the visual two-dimensional coordinate system; the horizontal extent of the top of the coal pile is outlined by providing a horizontal line coincident with the edge line of the cell.
Therefore, the coal pile represented in the visualized two-dimensional coordinate system based on the above rule (specifically, shown as a contour line representing the coal pile) has a minimum amplitude of one-time change of the height, that is, one unit scale on the vertical axis, and as described above, the coal bed height can be represented by preset levels, and if scale values 0, 1, 2, 3, and 4 are set on the vertical axis, each adjacent scale value can respectively represent that the coal pile has a 1-level height, a 2-level height, a 3-level height, and a 4-level height. The number of the specifically set levels and the actual height value corresponding to the unit level may be adjusted according to the actual use condition, which is not limited herein.
And S400, setting the color of the coal pile.
In this step, colors are filled in a closed curve defined by the contour line of each coal pile and the horizontal axis of the visualized two-dimensional coordinate system, thereby forming color patches to represent the corresponding coal piles.
Preferentially, the colors of the corresponding color blocks are set according to the color sequence set by the colors of the color blocks, and the color blocks with different colors can be used for distinguishing different coal piles.
And S500, setting the transparency of the coal pile.
On the one hand, the collection of the stacking data of each coal pile in the coal yard is based on the visual angle of the two-dimensional view, so when different coal piles are arranged far and near under the visual angle of the two-dimensional view, the coal pile arranged near can shield the coal pile arranged far, and the condition that different color blocks are overlapped or even completely covered can be generated in a visualized two-dimensional coordinate system. On the other hand, for the same coal type, there may be a case where the coal of the next batch is directly stacked on the coal pile of the previous batch, so that the coal pile of the previous batch is completely covered by the coal pile of the next batch or has an overlap with the coal pile of the next batch.
In the step, when the overlapping or covering of different color blocks is found, the outlines of the different color blocks can be completely displayed by adjusting the transparency of the corresponding color blocks. For which reason the different color blocks are caused by overlapping or covering, the effective distinction can be made according to the color and/or the transparency value of the color block.
And S600, calculating the coal storage amount of the coal pile.
In the step, the coal storage amount (ton) of the corresponding coal pile is calculated according to the area of the color block.
In some embodiments, the area of the color block may be multiplied by a fixed factor to calculate the approximate coal inventory for the coal pile.
The calculation formula of the coal storage amount in the embodiment is as follows:
wherein C represents the amount of stored coal, ρ represents the bulk density, and SiDenotes the area of the ith layer in the color patch, KiThe volume conversion factor of the i-th layer is expressed. E.g. in a visual two-dimensional coordinate system with a scale 1, 2, 3 … … n on its longitudinal axis, S1I.e. the area of the color block in the range of the ordinate interval (0, 1), S2I.e. the area … … S of the color block in the range of the coordinate interval (1, 2) of the vertical axisnI.e. the area of the color block in the coordinate interval (n-1, n) of the vertical axis. In view of S of the same area1～SnThe actual corresponding volumes of the layers are different, so that the color block area of each layer is multiplied by the corresponding volume conversion factor K when converting into the volumei，KiIs a parameter related to the coordinate ratio of the visual two-dimensional coordinate system and the repose angle of the stockpile.
