1 is a simplified diagram of a coal pile, showing a start point (x _m , start point) and an end point (x _n , end point).

As shown in FIG. 1, a pile of coal (hereinafter referred to as a 'pile') can be represented by a side view (1), a front view (4) and a top view (5), where the X axis is length, the Y axis is width and Z axis means height.

In side and plan views, x _m (2) represents the starting point of the file, x _n (3) represents the end point of the file, and the four coordinates (x _m , y ₁ , z ₀ ), (x _{m '} , y ₂ , z ₀ ), (x _n , y ₁ , z ₀ ), (x _n , y ₂ , z ₀ ) and the coordinates (Z) from the side view, ie Z ₀ to Z _i , to calculate the volume of the file. Can be.

It is a side view and a top view notation schematic diagram of a layer low coal.

As shown in Fig. 2, the piled low pile is all that the thick solid line side surface 1 and the plane 1 'are visible (hereinafter, the appearance is referred to as a pile). In practice, however, another file 3 is superimposed on the first file 2 (hereinafter, the file 2 and the file 3 are respectively referred to as 'navigation'). In chronological order, the files 2 are stacked first, and then the files 3 are stacked. By overlapping the plan views (2 ') and (3') of each file, it can be seen that the small square boxes of (4), (5), and (6) exist in the outline (1 ').

Figure 3 is a flow chart of the low-cost anti-difference volume calculation.

Here, the double low-volume discrepancy volume calculation is a conventional commercial computer consisting of a central processing unit, a mass storage device such as a hard disk or a solid state disk, a volatile memory device, an input device such as a keyboard or a mouse, and an output device such as a monitor or a printer. It can be implemented in

In step S1, in order to start calculating the volume of the coal pile, first, three-dimensional cloud point data is generated. Point cloud data may use any measurement technique, such as photogrametry or laser scanners. You can use any 3D software such as Pix4D, Photomodeler, 3D CAD, Arc GIS, or Explorer pro to implement three-dimensional modeling using point cloud data.

In step S1, pID is file unloading order, Q is loading amount, d is date, x is length, y is width and z is height. Of course, at this time, attributes such as types may be stored for each file of coal.

In step S2, three-dimensional coordinate values, lengths and volumes are calculated through 3D modeling from the above-described three-dimensional software. For example, four coordinates (x _m , y ₁ , z ₀ ), (x _{m '} ) can be identified by the method described with reference to FIG. , y ₂ , z ₀ ), (x _n , y ₁ , z ₀ ), (x _n , y ₂ , z ₀ ).

In step S3, the coordinates defined as above (x _m , y ₁ , z ₀ ), (x _{m '} , y ₂ , z ₀ ), (x _n , y ₁ , z ₀ ), (x _n , y ₂ , z ₀ ) to search for data of files of different sizes in reverse chronological order. If the retrieved coordinate data is the same as the data of the present day and the volume is the same, this means that the volume does not need to be recalculated with a file that is in the same state or the non-overlapping file of the last day, and thus the calculation of the volume discrimination is terminated.

In step S4, if another file exists, the search continues to check how many differences are found when the file is no longer present.

In step S5, as shown in FIG. 1 for each found difference and data, the sin table of each difference is extracted, and a top view and a side view are drawn.

In step S6, similar coordinates (side view and top view) are generated as shown in FIG. 2 by superimposing respective coordinates for each term on one x and y coordinate plane.

In step S7, on the basis of the side view and the top view drawn by step S6, the starting and ending points of the jet are adjusted and changed. For example, based on the side view, adjust and change the starting point and the end point of each file in the floor plan to the starting point and the end point of the discrimination.

In step S8, if a square box as shown in Fig. 2 is made, the volume is calculated based on the file as shown in Fig. 2 (1). That is, the volume of each column of the date file is calculated based on the start point and the end point of each box (column) formed in the floor plan. This volume can be obtained by 3D software such as Pix4D, Photomodeler, 3D CAD, Arc GIS, Explorer pro as described above.

In step S9, the volume for each column is calculated sequentially from the oldest difference to 1 to n (where n is a natural number). That is, each volume is calculated by the number of square boxes. This is defined as the "square box volume value".

In step S10, apart from the above, the volume for each difference (column) in each box is calculated and sequentially added from the old difference. This can be defined as a "sequential sum."

In step S11, if the "sequential sum" of the differences is greater than or equal to the same "square box volume value" in step S8, the calculation is aborted. That is, the calculation is stopped if the row sum value of the row in the same column is larger than the volume of each column of the date.

Here, the final added term may be defined as the “final term”, and the remaining value obtained by subtracting the “square box volume value” from the “sequential sum” may be defined as the “difference value”.

In step S12, if the sum of the rows by the same column is greater than the volume by the column of the day, the final trajectory volume is equal to the final volume of the volume minus "the sum of the rows by the column minus the volume of the column by that date". Becomes the same. In other words, subtracting the "difference value" from the last difference value of the "sequential sum" becomes the current residual value.

In step S13, the calculated difference value can be obtained by adding the calculated row difference value in a square box to a box value within a box. That is, the volume of each difference is calculated by summing the volume difference of each column formed in the side view for each row.

4 is an exemplary embodiment of calculating the volume of different low carbon anti-difference.

In FIG. 4, the flowchart of the left side will be described together using the side view and the plan view of the three-dimensional coordinates shown on the right side.

① shows the data surveyed today. Today within 4 coordinates (x _m , y ₁ , z ₀ ), (x _{m '} , y ₂ , z ₀ ), (x _n , y ₁ , z ₀ ), (x _n , y ₂ , z ₀ ) Data was searched for files of different sizes in reverse chronological order.

There was file data of ② on D-1, and file data of ③ on D-2.

Here, a file having a different size means four coordinates (x _m , y ₁ , z ₀ ), (x _{m '} , y ₂ , which the file of the present day, the file of D-1, and the file of D-2 have, respectively. , z ₀ ), (x _n , y ₁ , z ₀ ), or at least one of (x _n , y ₂ , z ₀ ) is different.

The data retrieved was not the same as today's survey data, and the total number of files was three.

As shown in (4), today's survey data and two searched file data are shown on one x and y plane.

As shown in ⑤, the box of the file, which is the floor plan, has been changed based on the side view. This means that the starting point (x _m ) and the ending point (x _n ) of each file were adjusted to change the starting point and the ending point of the discrimination.

As in ⑥, five square boxes were formed as a result.

As in ⑦, the volume was calculated for each box from the oldest first order. Here, we know all the values of the coordinates x, y, and z, so we can enter these coordinates into 3D software such as Pix4D, Photomodeler, 3D CAD, Arc GIS, and Explorer pro to calculate the volume for each square box.

Next, as in (8), volume 2 was calculated for each square box. Paragraph 2 is the result of subtracting D-2 file ③ from D-1 file ②. In this case, since the values of the coordinates x, y, and z are all known, these coordinate values can be input to 3D software such as Pix4D, Photomodeler, 3D CAD, Arc GIS, and Explorer pro to calculate the volume for each square box.

As in ⑨, volume 3 was calculated for each box by square box. Step 3 is the result of subtracting D-1 ② file from D file ①. In this case, since the values of the coordinates x, y, and z are all known, these coordinate values can be input to 3D software such as Pix4D, Photomodeler, 3D CAD, Arc GIS, and Explorer pro to calculate the volume for each square box.

In FIG. 4, the lower right table divides boxes into the same size as described above, and calculates and shows the sum of each box ⑪ (column system) and the value of the variance value ⑫ (portometer) as an example. That is, ⑪ is the sum of the column-by-column differences, and ⑫ is the sum of the rows. In other words, the vertical cell is a column and the horizontal cell is a row.

FIG. 5 is a main screen of applying a low-low volume discrimination algorithm according to an embodiment, and FIG. 6 is a UI (user interface) report screen of an embodiment applying a volume calculation algorithm according to a low layer. In the present invention, the UI by the program to which the above-described algorithm is applied may be variously changed, and the present invention is not limited to the UI.

In this manner, the present invention provides a method for managing data by managing spatial files by dividing them into spatial coordinate values in chronological order as shown in FIGS. 1 and 2. In addition, the present invention provides a method for calculating the volume and coordinate values of the overlapped file in the order shown in FIGS. 3 and 4. Furthermore, the present invention provides a method of dividing the spatial coordinate value by box, calculating the current pile volume by box, and then calculating the volume of the remaining residual difference by comparing the pile volume with the pile volume in time order. . Finally, the present invention is applicable not only to coal, but also to all piles stored in piles, such as minerals and grains.

In general, in order to operate the low coal, which is a coal storage space, it is necessary to efficiently manage the inventory by using a limited low coal space.目測). However, the neck side is empirical, so it was difficult to produce a certain amount of heat by mixing the coal.

In addition, the method of using photogrammetry and laser scanner can calculate the quantity by implementing the three-dimensional low-tank pile in the computer virtual space, but it is not possible to classify and calculate the various shots stacked in the low-tank pile. .

Therefore, by linking and analyzing the spatial data and the attribute data, even if the stacked multiple shots cannot be visually distinguished, by implementing an algorithm that calculates the volume for each type of coal, the calorific value of the mixed coal is kept constant for power generation. As a result, it is possible to secure low space and economical space management by securing the power generation quality and not affecting the quality of the bottom bottom.
