Description

Technical Field

[0001] This invention relates to the field of coal blending technology, and in particular to a coal yard coal blending method and system. Background Technology

[0002] Coal mining equipment commonly used in coal yards consists of various production facilities. However, due to the relatively concentrated distribution of coal in some areas and the scattered distribution in others, and the potential for gaps between different coal types, users often lack clarity regarding the spatial relationships between different coal piles and whether there is any available space for extraction. This can significantly reduce the efficiency of coal mining.

[0003] Therefore, this invention proposes a method and system for coal extraction and proportioning in a coal yard. Summary of the Invention

[0004] This invention provides a coal extraction and blending method and system for coal yards, which determines the lines of different coal qualities in the coal yard and then effectively determines the effective coal extraction location of different coal piles according to the coal extraction requirements, thereby greatly improving coal extraction efficiency.

[0005] This invention provides a method for coal blending in a coal yard, comprising:

[0006] Step 1: Locate the current coal pile and boundary line of the target coal yard, and construct the coal yard and coal pile structure diagram of the target coal yard;

[0007] Step 2: Based on the center coordinates of each coal pile in the coal yard coal pile structure diagram, plan the coal pile lines of the same coal quality;

[0008] Step 3: Obtain the coal extraction requirements of the coal yard, and extract the required coal quality and corresponding required coal weight involved in the coal extraction requirements;

[0009] Step 4: Locate the first line corresponding to the required coal quality and obtain the coal distribution map based on all the first lines;

[0010] Step 5: Determine the corresponding initial coal extraction location based on the first boundary range and first weight of each coal pile in the coal extraction distribution map;

[0011] Step 6: Determine if there is an initial position segment in the remaining first line that has a preset relationship with the same first line;

[0012] Step 7: Based on the initial coal extraction location, the initial position segment, and the required coal weight, locate the first position within the same first line segment;

[0013] Step 8: Based on the first position on each locked first line, plan the coal extraction route to achieve effective coal extraction.

[0014] Preferably, the current coal pile and its boundary line in the target coal yard are locked to construct a coal yard and coal pile structure diagram of the target coal yard, including:

[0015] The target coal yard is photographed from a downward angle to obtain the first image;

[0016] Pixel analysis is performed on the first image to calibrate the coal piles in the target coal yard, resulting in a second image;

[0017] The second image is compared and analyzed with a standard image of the target coal yard where no coal piles are placed. Based on the calibration results of each coal pile, it is determined whether the corresponding coal pile is an independent coal pile.

[0018] If all are independent coal piles, then based on the second image, the boundary line of each current coal pile is obtained, and then the coal pile structure diagram of the corresponding target coal yard is obtained;

[0019] If there are non-independent coal piles, the non-independent position of the non-independent coal piles based on the standard image is locked, and the non-independent coal piles at the non-independent positions are photographed laterally from four directions to determine whether there is a connecting area at the non-boundary position of the non-independent coal piles.

[0020] If it exists, obtain the region space of the connecting region;

[0021] If the area space is smaller than the preset space, the non-independent coal pile is determined to be two coal piles connected at a height;

[0022] Otherwise, delete the coal extraction locations between the non-independent coal piles;

[0023] Based on the judgment results and all the independent coal piles, a coal yard coal pile structure diagram is constructed.

[0024] Preferably, based on the center coordinates of each coal pile in the coal yard coal pile structure diagram, coal pile lines of the same coal quality are planned, including:

[0025] Lock the first center point of each independent coal pile in the coal yard coal pile structure diagram, the second center point of the highly connected coal piles, and the standard center point of the standard coal pile area in the standard image corresponding to the non-independent coal piles;

[0026] Based on the regional coal quality of each standard coal pile area in the standard image, the center points are connected to obtain coal pile lines of the same coal quality.

[0027] Preferably, the initial coal extraction location is determined based on the first boundary range and first weight of each coal pile in the coal extraction distribution map, including:

[0028] Based on the coal pile attributes of each coal pile diagram and the distribution direction based on the first line, determine the corresponding first boundary range;

[0029] Analyze the independent location regions within the first boundary range and determine the acceptable weight for each independent location within each independent location region;

[0030] Based on the ratio of the available weight to the first weight, an initial coal extraction location is selected from all independent locations.

[0031] Preferably, determining that there exists an initial position segment in the remaining first line that has a preset relationship with the same first line includes:

[0032] Based on the coal mining distribution map, it is determined that there are intersection positions that intersect with the same first line and adjacent positions that are adjacent to it in the remaining first line.

[0033] Determine the intersection direction at the intersection location and the intersection boundary in each direction;

[0034] Based on the intersection direction and intersection boundary, the first selection boundary is determined;

[0035] Determine the adjacent boundaries of the adjacent positions, and determine the second selection boundary;

[0036] The initial position segment is determined based on the first and second bounding box boundaries.

[0037] Preferably, based on the initial coal extraction location, the initial location segment, and the required coal weight, locking the first position within the same first line segment includes:

[0038] Determine the initial coal extraction location and the overlapping position of the initial location segment;

[0039] If there is only one overlapping position, the overlapping position is taken as the first position. When the remaining coal weight corresponding to the overlapping position is insufficient to support the corresponding required coal weight, the second coal pile that meets the first weight requirement is selected from the remaining coal piles in the corresponding first line according to the first weight difference between the required coal weight and the remaining coal weight, and coal extraction continues.

[0040] If there is more than one overlapping position, the remaining coal weight at each overlapping position is sorted. When max{t1,t2,...,tn}>tx, the overlapping position corresponding to max{t1,t2,...,tn} is locked as the first position for coal extraction.

[0041] Otherwise, select n2 overlapping positions from the n1 overlapping positions that satisfy the path constraint and weight constraint, and then extract coal from them.

[0042] Preferably, based on the first position on each locked first line, a coal extraction route is planned to achieve effective coal extraction, including:

[0043] Extract the location coordinates of each first position, the coal weight based on each first position, and the coal extraction priority of each first position;

[0044] Based on the extraction results, the coal extraction route is obtained from the route planning model.

[0045] This invention provides a coal yard coal blending system, comprising:

[0046] The graph construction module is used to lock the current coal pile and the boundary line of the current coal pile in the target coal yard, and construct the coal yard and coal pile structure graph of the target coal yard.

[0047] The line planning module is used to plan coal pile lines of the same coal quality based on the center coordinates of each coal pile in the coal yard coal pile structure diagram.

[0048] The information extraction module is used to obtain the coal extraction requirements of the coal yard and extract the required coal quality and corresponding required coal weight involved in the coal extraction requirements.

[0049] The line locking module is used to lock the first line corresponding to the required coal quality and obtain a coal extraction distribution map based on all the first lines.

[0050] The initial position determination module is used to determine the corresponding initial coal extraction position based on the first boundary range and first weight of each coal pile in the coal extraction distribution map;

[0051] The position segment determination module is used to determine whether there is an initial position segment in the remaining first line that has a preset relationship with the same first line;

[0052] The position locking module is used to lock the first position in the same first line segment based on the initial coal taking position, the initial position segment, and the required coal weight;

[0053] The route planning module is used to plan coal extraction routes based on the first position on each locked first line, so as to achieve efficient coal extraction.

[0054] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the written description, claims, and drawings.

[0055] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0060] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0061] This invention provides a method for coal blending in a coal yard, such as... Figure 1 As shown, it includes:

[0062] Step 1: Locate the current coal pile and boundary line of the target coal yard, and construct the coal yard and coal pile structure diagram of the target coal yard;

[0063] Step 2: Based on the center coordinates of each coal pile in the coal yard coal pile structure diagram, plan the coal pile lines of the same coal quality;

[0064] Step 3: Obtain the coal extraction requirements of the coal yard, and extract the required coal quality and corresponding required coal weight involved in the coal extraction requirements;

[0065] Step 4: Locate the first line corresponding to the required coal quality and obtain the coal distribution map based on all the first lines;

[0066] Step 5: Determine the corresponding initial coal extraction location based on the first boundary range and first weight of each coal pile in the coal extraction distribution map;

[0067] Step 6: Determine if there is an initial position segment in the remaining first line that has a preset relationship with the same first line;

[0068] Step 7: Based on the initial coal extraction location, the initial position segment, and the required coal weight, locate the first position within the same first line segment;

[0069] Step 8: Based on the first position on each locked first line, plan the coal extraction route to achieve effective coal extraction.

[0070] In this embodiment, the current coal pile and its boundary line are obtained based on image analysis, such as... Figure 3 As shown, different coal piles a1 under the target coal yard and the corresponding boundary line b1 of the coal pile are shown.

[0071] In this embodiment, the center coordinates of each coal pile refer to the center position determined relative to the current boundary line of the coal pile, and the coordinates corresponding to that center position.

[0072] In this embodiment, since the coal quality corresponding to each coal pile is different, for example, there are coal piles a1, a2, a3, and a4, where the coal quality of coal piles a1 and a2 is the same, then the line connecting the center coordinates of coal piles a1 and a2 is established as the coal pile line of the same coal quality.

[0073] In this embodiment, the coal extraction demand of the coal yard includes the coal quality and the demand for different coal qualities. Therefore, the two required parameters can be obtained directly from the coal extraction demand of the coal yard.

[0074] In this embodiment, the number of coal piles in the coal mining distribution map is less than the number of coal piles in the coal yard coal pile structure map. The coal mining distribution map is constructed solely based on the first line, that is, the first line is extracted from the coal yard coal pile structure map.

[0075] In this embodiment, each coal pile diagram has a boundary range and weight. The initial coal extraction location is determined based on the wide boundary line within the boundary range, identifying a suitable boundary location area for the coal pile. Figure 1 There exists a boundary 01 for the coal pile. Figure 2 There exists a boundary 02, at which point the coal pile... Figure 1 With coal pile Figure 2 For adjacent coal piles, the empty area between boundaries 01 and 02 is the corresponding boundary location area. Since the lengths of the straight lines connecting the corresponding boundary points of boundaries 01 and 02 in the boundary location area are different, the corresponding distances will also be different. The longer the distance, the more suitable the location is as a coal extraction location.

[0076] In this embodiment, the preset relationship refers to the existing adjacent relationship and intersection relationship. For example, if the first line 1 and the second line 2 intersect, the corresponding intersection position is considered to be an intersection relationship between the two. For another example, if the end of line 1 is adjacent to the beginning of line 2, it is considered to be an adjacent relationship. The purpose of determining the initial position segment is to leave enough coal-taking space for the loader to effectively take coal, and the initial position segment is the existing coal-taking space, which is the coal-taking segment corresponding to the space.

[0077] In this embodiment, the location coordinates of the initial coal extraction location, the location coordinates of the initial location segment, and the weight of the coal corresponding to the initial coal extraction location and the weight of the coal corresponding to the initial location segment are determined. After these are determined, the overlapping location corresponding to the initial coal extraction location and the initial location segment is prioritized as the priority location for coal extraction, thereby maximizing the distance between different coal piles and facilitating the extraction of coal from different coal piles. Furthermore, after determining the existing priority locations, the final location can be determined based on the weight of the coal at that priority location.

[0078] In this embodiment, for example, there are initial positions 1, 2, and 3, and initial position segments 01 and 02. The initial position 1 overlaps with the initial position segment 01. In this case, the initial position 1 can be used as the priority position. Since the coal weight corresponding to the initial position 1 can meet the coal extraction requirements, the first locked position is the initial position 1.

[0079] In this embodiment, since the weight of coal in each coal pile and the spacing between coals are different, there may be multiple first positions on the same first line to facilitate the planning of subsequent coal extraction routes.

[0080] In this embodiment, the coal extraction route is planned to meet the coal extraction demand in the shortest possible time.

[0081] The beneficial effects of the above technical solution are: by determining the lines of different coal qualities in the coal yard, and then by effectively determining the effective coal extraction location of different coal piles according to the coal extraction requirements, the coal extraction efficiency is greatly improved.

[0082] This invention provides a method for coal extraction and proportioning in a coal yard, which involves locking the current coal pile and its boundary line in a target coal yard, and constructing a coal pile structure diagram of the target coal yard, including:

[0083] The target coal yard is photographed from a downward angle to obtain the first image;

[0084] Pixel analysis is performed on the first image to calibrate the coal piles in the target coal yard, resulting in a second image;

[0085] The second image is compared and analyzed with a standard image of the target coal yard where no coal piles are placed. Based on the calibration results of each coal pile, it is determined whether the corresponding coal pile is an independent coal pile.

[0086] If all are independent coal piles, then based on the second image, the boundary line of each current coal pile is obtained, and then the coal pile structure diagram of the corresponding target coal yard is obtained;

[0087] If there are non-independent coal piles, the non-independent position of the non-independent coal piles based on the standard image is locked, and the non-independent coal piles at the non-independent positions are photographed laterally from four directions to determine whether there is a connecting area at the non-boundary position of the non-independent coal piles.

[0088] If it exists, obtain the region space of the connecting region;

[0089] If the area space is smaller than the preset space, the non-independent coal pile is determined to be two coal piles connected at a height;

[0090] Otherwise, delete the coal extraction locations between the non-independent coal piles;

[0091] Based on the judgment results and all the independent coal piles, a coal yard coal pile structure diagram is constructed.

[0092] In this embodiment, "directly downward" refers to taking a picture from directly above the coal yard, from top to bottom. Generally, the higher the coal pile, the greater the corresponding gray value. Therefore, the different locations of the coal pile can be effectively distinguished by the captured images. Thus, based on the first image, the calibrated image, which is the second image, can be obtained through pixel analysis.

[0093] In this embodiment, since each coal yard has its own coal placement standard, which can be obtained based on a standard image, the coal pile can be effectively determined as independent based on the calibration results during subsequent comparative analysis.

[0094] In this embodiment, the standard image only divides each coal placement area in the coal yard, and the types of coal corresponding to different coal placement areas are different.

[0095] In this embodiment, by comparing and analyzing the standard image with the second image, the independent and non-independent judgment of the actual coal pile can be effectively achieved according to the boundary line.

[0096] In this embodiment, the standard image contains regions 1, 2, and 3. However, during the comparative analysis, there is a non-independent coal pile (the boundary line determined after the photo is not obvious) that occupies regions 1 and 2. Therefore, it is necessary to take photos of the non-independent coal pile from four directions (based on the four directions of east, west, south, and north) to determine whether there is a connecting area in different directions. The connecting area refers to a connection between two coal piles where there is a certain height, such as 30cm or more. In this case, the corresponding coal pile is regarded as the height connecting coal pile.

[0097] In this embodiment, the connecting area refers to the connecting part of two highly connected coal piles, and the area space refers to the connecting space corresponding to the connecting part, which is determined according to volume.

[0098] In this embodiment, the coal extraction location is deleted to avoid situations such as unreasonable or inconvenient coal extraction due to contact between different types of coal piles.

[0099] In this embodiment, the coal yard coal pile structure diagram includes the positions corresponding to all independent coal piles and highly connected coal piles, and the positions between non-independent coal piles do not exist.

[0100] The beneficial effects of the above technical solution are: by taking pictures of the coal yard, calibrating and comparing the coal piles, a reasonable judgment can be made on the existence of connecting areas between non-independent coal piles, and then the coal extraction locations between non-independent coal piles can be deleted, ensuring the reliability of the coal pile and coal yard structure map and facilitating the efficiency of subsequent coal extraction.

[0101] This invention provides a method for coal blending in a coal yard, which involves planning coal pile lines of the same coal quality based on the center coordinates of each coal pile in the coal yard coal pile structure diagram, including:

[0102] Lock the first center point of each independent coal pile in the coal yard coal pile structure diagram, the second center point of the highly connected coal piles, and the standard center point of the standard coal pile area in the standard image corresponding to the non-independent coal piles;

[0103] Based on the regional coal quality of each standard coal pile area in the standard image, the center points are connected to obtain coal pile lines of the same coal quality.

[0104] In this embodiment, the connecting line between two standard center points is a dashed line, the connecting line between two first center points is a solid line, the connecting line between two second center points is a semi-dashed line, the connecting line between a standard center point and a first center point is a dashed line near the standard center point and a solid line near the first center point, the connecting line between a standard midline point and a second center point is a dashed line near the standard center point and a semi-dashed line near the second center point, and the connecting line between a first center point and a second center point is a solid line near the first center point and a semi-dashed line near the second center point.

[0105] In this embodiment, the coal pile line refers to the line obtained by connecting the center points of the same coal material in sequence.

[0106] The beneficial effects of the above technical solution are: by connecting the center points of different coal types, it is convenient to construct coal pile lines, providing contact for subsequent analysis, and by using different solid and dashed lines during the construction process, it further provides a basis for determining the initial coal extraction location.

[0107] This invention provides a coal extraction and proportioning method for a coal yard, which determines the corresponding initial coal extraction location based on the first boundary range and first weight of each coal pile in the coal extraction distribution map, including:

[0108] Based on the coal pile attributes of each coal pile diagram and the distribution direction based on the first line, determine the corresponding first boundary range;

[0109] Analyze the independent location regions within the first boundary range and determine the acceptable weight for each independent location within each independent location region;

[0110] Based on the ratio of the available weight to the first weight, an initial coal extraction location is selected from all independent locations.

[0111] In this embodiment, the coal pile attribute refers to whether the coal pile is independent, non-independent, or highly interconnected.

[0112] In this embodiment, the distribution direction refers to the direction of the lines corresponding to the same coal quality.

[0113] In this embodiment, the first boundary range refers to the range between the boundary of the corresponding coal pile determined based on the image and the boundary of the adjacent coal pile.

[0114] In this embodiment, the independent location area refers to an area that can accommodate a loader for independent coal extraction.

[0115] In this embodiment, since the amount of coal that the loader takes from the coal pile varies at different locations, the amount of coal taken can be regarded as the takeable weight. The first weight refers to the total weight of coal that needs to be taken from this coal.

[0116] In this embodiment, the initial coal extraction location is selected in order to extract as much coal as possible from the corresponding location and save coal extraction time.

[0117] The beneficial effects of the above technical solution are: by determining the boundary range based on the properties and distribution direction of the coal pile, and by combining the available weight at different locations, the initial coal extraction location can be effectively selected, thereby improving coal extraction efficiency.

[0118] This invention provides a method for coal extraction and proportioning in a coal yard, comprising determining that there exists an initial position segment in the remaining first line that has a preset relationship with the same first line, including:

[0119] Based on the coal mining distribution map, it is determined that there are intersection positions that intersect with the same first line and adjacent positions that are adjacent to it in the remaining first line.

[0120] Determine the intersection direction at the intersection location and the intersection boundary in each direction;

[0121] Based on the intersection direction and intersection boundary, the first selection boundary is determined;

[0122] Determine the adjacent boundaries of the adjacent positions, and determine the second selection boundary;

[0123] The initial position segment is determined based on the first and second bounding box boundaries.

[0124] In this embodiment, the selection boundary refers to the boundary of the coal pile, and the entire selection of the coal pile edge can be used as the corresponding selection boundary.

[0125] The beneficial effects of the above technical solution are: by determining the selection boundary corresponding to the preset relationship, the existing initial position segment can be effectively determined, providing a basis for subsequent position determination and further ensuring the efficiency of coal extraction.

[0126] This invention provides a coal extraction and proportioning method for a coal yard, which, based on the initial coal extraction location, the initial location segment, and the required coal weight, locks a first position within the same first line segment, including:

[0127] Determine the initial coal extraction location and the overlapping position of the initial location segment;

[0128] If there is only one overlapping position, the overlapping position is taken as the first position. When the remaining coal weight corresponding to the overlapping position is insufficient to support the corresponding required coal weight, the second coal pile that meets the first weight requirement is selected from the remaining coal piles in the corresponding first line according to the first weight difference between the required coal weight and the remaining coal weight, and coal extraction continues.

[0129] If there is more than one overlapping position, the remaining coal weight at each overlapping position is sorted. When max{t1,t2,...,tn}>tx, the overlapping position corresponding to max{t1,t2,...,tn} is locked as the first position for coal extraction.

[0130] Otherwise, select n2 overlapping positions from the n1 overlapping positions that satisfy the path constraint and weight constraint, and then extract coal from them.

[0131] In this embodiment, n1 is greater than n2.

[0132] In this embodiment, the route constraint condition refers to: Among them, l i1,+1 Let represent the distance from the i1th overlapping position to the i1+1th overlapping position; and j represent the jth possible solution, which contains n2 overlapping positions; L represents the path constraint value.

[0133] Weight constraints refer to: Among them, gi1 M represents the weight of coal taken at the i1th overlapping position; M represents the required weight of coal to be taken.

[0134] The beneficial effects of the above technical solution are: by judging the overlapping position of the initial coal extraction location and the initial coal extraction section, coal can be extracted from a reasonable coal pile, which facilitates the efficiency of subsequent coal extraction.

[0135] This invention provides a coal extraction and proportioning method for coal yards, which plans a coal extraction route based on the first position on each locked first line to achieve effective coal extraction, including:

[0136] Extract the location coordinates of each first position, the coal weight based on each first position, and the coal extraction priority of each first position;

[0137] Based on the extraction results, the coal extraction route is obtained from the route planning model.

[0138] In this embodiment, the coal extraction priority is determined as follows:

[0139]

[0140] Wherein, s1(x,y) represents the coal extraction location superiority factor corresponding to the position coordinates (x,y) of the first position, with a value range of (0,1); s2(g) represents the coal extraction weight superiority factor corresponding to the first position, with a value range of (0,1); e represents the exponential function symbol; Y0 represents the corresponding priority value;

[0141] From the value-priority mapping table, the priority is mapped to the same priority value.

[0142] In this embodiment, the route planning model is pre-trained and is trained based on the coordinates of different coal extraction locations, the weight of coal extracted at different locations, the priority of the coal extraction locations, and the corresponding coal extraction routes as samples.

[0143] The beneficial effects of the above technical solution are: by analyzing the extracted results based on the route planning model, the coal extraction route can be effectively obtained, and high efficiency in coal extraction can be achieved through the coal extraction route.

[0144] This invention provides a coal yard coal blending system, such as... Figure 2 As shown, it includes:

[0145] The graph construction module is used to lock the current coal pile and the boundary line of the current coal pile in the target coal yard, and construct the coal yard and coal pile structure graph of the target coal yard.

[0146] The line planning module is used to plan coal pile lines of the same coal quality based on the center coordinates of each coal pile in the coal yard coal pile structure diagram.

[0147] The information extraction module is used to obtain the coal extraction requirements of the coal yard and extract the required coal quality and corresponding required coal weight involved in the coal extraction requirements.

[0148] The line locking module is used to lock the first line corresponding to the required coal quality and obtain a coal extraction distribution map based on all the first lines.

[0149] The initial position determination module is used to determine the corresponding initial coal extraction position based on the first boundary range and first weight of each coal pile in the coal extraction distribution map;

[0150] The position segment determination module is used to determine whether there is an initial position segment in the remaining first line that has a preset relationship with the same first line;

[0151] The position locking module is used to lock the first position in the same first line segment based on the initial coal taking position, the initial position segment, and the required coal weight;

[0152] The route planning module is used to plan coal extraction routes based on the first position on each locked first line, so as to achieve efficient coal extraction.

[0153] The beneficial effects of the above technical solution are: by determining the lines of different coal qualities in the coal yard, and then by effectively determining the effective coal extraction location of different coal piles according to the coal extraction requirements, the coal extraction efficiency is greatly improved.
