[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0047] Embodiment 1

[0048] An embodiment of the present invention proposes a method for processing coal pile measurement data, which is suitable for determining the coal storage position of each batch when adding coal to a single coal pile in batches, and the coal storage position of each batch after the coal in the single coal pile is used.

[0049] Figure 1 is a flow chart of the coal pile measurement data processing method in the embodiment, refer to Figure 1 , the coal pile measurement data processing method includes:

[0050] S101. Obtain coal pile adding measurement data, and generate multiple coal pile increment models based on the coal pile adding measurement data.

[0051] Illustratively, in this embodiment, the coal pile adding coal measurement data includes multiple data subsets, each data subset corresponds to the point cloud data of the coal pile after one coal adding, and the first original point cloud data of the coal pile before coal adding.

[0052] In this embodiment, there is no limitation on the method of generating point cloud data. The point cloud data may be measurement data of a three-dimensional laser scanner, or point cloud data obtained by processing a depth image taken by a multi-eye vision system.

[0053] Exemplarily, in this embodiment, the incremental model of the coal pile is stored in the form of point cloud data, and at the same time, the coal pile measurement model can be displayed in the form of a three-dimensional model.

[0054] For example, in this embodiment, the number of coal pile increment models is the same as the number of times coal is added, and one coal pile increment model corresponds to the increment of the coal pile after a batch of coal is added. Generating multiple coal pile increment models through coal pile addition measurement data can be implemented in the following manner:

[0055] Obtaining point cloud data of the coal pile after two consecutive coal additions, recorded as first point cloud data and second point cloud data, wherein the point cloud data of the coal pile after the zeroth coal addition is the first original point cloud data of the coal pile;

[0056] Compare the first point cloud data with the second point cloud data, eliminate coordinate points with the same coordinate values ​​in the first point cloud data and the second point cloud data, generate incremental model point cloud data through the remaining first point cloud data and second point cloud data, and use the incremental model point cloud data to represent the incremental model of the coal pile after the corresponding coal addition.

[0057] Optionally, in this scheme, a coal pile incremental model can also correspond to the increment of the coal pile after multiple batches of coal addition, wherein the specific number of multiple batches can be set according to management needs. At this time, the point cloud data of the coal pile after two selected coal additions is obtained, and then the corresponding coal pile incremental model is generated.

[0058] S102. Obtain coal pile consumption measurement data, and generate a coal pile reduction model based on the coal pile consumption measurement data.

[0059] Exemplarily, the coal pile consumption measurement data includes two data subsets, which respectively correspond to the second original point cloud data before the coal pile is consumed and the point cloud data after the coal pile is consumed once.

[0060] Exemplarily, in this embodiment, the coal pile reduction model is stored in the form of point cloud data.

[0061] Exemplarily, in this embodiment, generating a coal pile reduction model through coal pile consumption measurement data can be implemented in the following manner:

[0062] Obtain the second original point cloud data and the point cloud data of the coal pile after being consumed once, and record them as the third point cloud data and the fourth point cloud data;

[0063] Compare the third point cloud data with the fourth point cloud data, eliminate coordinate points with the same coordinate values ​​in the third point cloud data and the fourth point cloud data, generate reduction model point cloud data through the remaining third point cloud data and fourth point cloud data, and represent the coal pile reduction model through the reduction point cloud data.

[0064] S103. Update each coal pile increment model through the coal pile reduction model, and respectively determine the change amount of the increment model of each coal pile increment model after one consumption of the coal pile.

[0065] Based on steps S101 and S102, in this step, the update of the coal pile increment model can be achieved in the following manner:

[0066] Successively determine the plane coordinates of each coordinate point in the increment model point cloud data. For each plane coordinate, find the increment model coordinate point in the increment model point cloud data that is the same as this plane coordinate, and find the reduction coordinate point in the reduction model point cloud data that is the same as this plane coordinate;

[0067] Exemplarily, after coal addition, the coal in the added coal pile has a certain thickness in the vertical direction. For a plane coordinate (x1, y1), if the increment model coordinate points include the first increment coordinate point (x1, y1, z1) and the second increment coordinate point (x1, y1, z2), and z1>z2, and the reduction coordinate points include the first reduction coordinate point (x1, y1, z3) and the second reduction coordinate point (x1, y1, z4), and z3>z4, then:

[0068] If z4>z1, then retain the first increment coordinate point and the second increment coordinate point;

[0069] If z2<z4<z1, then update the first increment coordinate point to (x1, y1, z3) and retain the second increment coordinate point;

[0070] If z4<z2, then delete the first increment coordinate point and the second increment coordinate point.

[0071] The determination of the change amount of the increment model of each coal pile increment model can be achieved in the following manner:

[0072] For a coal pile increment model, calculate the coal pile increment volume through the point cloud data of the coal pile increment model before update, denoted as V1, and calculate the coal pile increment volume through the point cloud data of the coal pile increment model after update, denoted as V2;

[0073] The change amount of the increment model is the difference between V1 and V2.

[0074] Exemplarily, in this embodiment, the coordinate point data corresponding to the coal pile increment model is stored in the database. When the coal pile is consumed once and subsequent coal addition is carried out in batches, a new coal pile increment model is still generated in the manner described in step S101;

[0075] After the subsequent coal pile is consumed, a new coal pile reduction model is generated in the manner described in step S102, and all coal pile increment models and the corresponding change amounts of the increment models are updated in the manner described in step S103.

[0076] This embodiment proposes a method for processing coal pile measurement data. This method generates multiple coal pile increment models by processing coal pile addition measurement data, wherein one coal pile increment model corresponds to the spatial position of one batch of added coal, based on which the coal pile conditions of different batches of added coal can be effectively grasped. In addition, when the coal pile is consumed, this method generates a coal pile reduction model by processing the coal pile consumption measurement data, updates each coal pile increment model by the coal pile reduction model, and then determines the spatial position of different batches of coal after the coal is consumed, so that relevant personnel can effectively grasp the usage of different batches of coal.

[0077] Figure 2 is another flow chart of the coal pile measurement data processing method in the embodiment, refer to Figure 2 As an implementable solution, the coal pile measurement data processing method can also be:

[0078] S201. Obtain coal pile adding measurement data, and generate multiple coal pile increment models based on the coal pile adding measurement data.

[0079] S202. Obtain coal pile consumption measurement data, and generate a coal pile reduction model based on the coal pile consumption measurement data.

[0080] S203. Update each coal pile increment model through the coal pile reduction model, and determine the increment model change of each coal pile increment model after one consumption of the coal pile.

[0081] S204. Obtain the coal addition mass data, and determine the remaining mass corresponding to each coal pile increment model after the coal pile is consumed once.

[0082] In this solution, the implementation method of steps S201 to S203 is the same as the corresponding contents recorded in steps S101 to S103.

[0083] Exemplarily, the coal addition quality data includes the coal addition quality of each batch. In one possible implementation scheme, determining the quality remaining quantity corresponding to each coal pile increment model can be implemented as follows:

[0084] For a coal pile increment model, the mass of added coal corresponding to the coal pile increment model is obtained, which is recorded as T. After one consumption, the mass remaining corresponding to the coal pile increment model is:

[0085]

[0086] Wherein, V1 is the incremental volume of the coal pile calculated by using the point cloud data of the incremental model of the coal pile before updating, and V2 is the incremental volume of the coal pile calculated by using the point cloud data of the incremental model of the coal pile after updating.

[0087] In this solution, there is no limitation on the method of calculating the incremental volume of the coal pile through point cloud data, and any method in the prior art can be used to calculate the incremental volume of the coal pile.

[0088] In one possible implementation scheme, if the mass of the coal consumed this time and the density of the coal added to the coal pile in each batch are known, the mass consumption corresponding to each coal pile increment model can be determined as follows:

[0089]

[0090] In the above formula, ρ i is the density of the coal added to the coal pile in the i-th batch, V1 i is the incremental volume of the coal pile in the incremental model corresponding to the i-th batch, V2 i is the incremental volume of the coal pile corresponding to the updated batch i of the coal pile incremental model, T m is the mass of coal consumed this time, and n is the total number of batches.

[0091] exist Figure 1 On the basis of the beneficial effects of the scheme shown, this scheme can also determine the mass consumption of different batches of coal after the coal is consumed, so that relevant personnel can conduct relevant data statistics and provide convenience for production guidance.

[0092] Figure 3 is another flow chart of the coal pile measurement data processing method in the embodiment, refer to Figure 3 As an implementable solution, the coal pile measurement data processing method can also be:

[0093] S301. Obtain coal pile adding measurement data, and generate multiple coal pile increment models based on the coal pile adding measurement data.

[0094] In this solution, the implementation method of step S301 is the same as that recorded in step S101.

[0095] S302. Obtain coal pile consumption measurement data, and generate a coal pile reduction model based on the coal pile consumption measurement data.

[0096] In this solution, the implementation method of step S302 is the same as that recorded in step S102.

[0097] S303. Obtain the compaction coefficient corresponding to each coal pile incremental model respectively, adjust the corresponding coal pile incremental model according to the compaction coefficient, and generate a coal pile incremental compaction model.

[0098] Exemplarily, in this solution, the compaction coefficient is a calibration value, and the calibration test process can be designed according to actual operational requirements.

[0099] In one possible implementation, the compaction coefficient may specifically include a coal quality coefficient, a location coefficient, and a manual coefficient.

[0100] Among them, the coal quality coefficient of each coal pile increment model is related to the hardness and humidity of the corresponding coal. The higher the hardness and the greater the humidity, the closer the coal quality coefficient is to 1;

[0101] The position coefficient of each coal pile increment model is related to its corresponding spatial position. The closer the spatial position is to the original coal pile before adding coal, the closer the position coefficient is to 1.

[0102] The labor coefficient is a set value. If a coal pusher is not used for compaction, the labor coefficient is greater than 1. If a coal pusher is used for compaction, the labor coefficient is equal to 1.

[0103] For example, when the compaction coefficient includes the coal quality coefficient, the location coefficient and the manual coefficient, the compaction coefficient corresponding to each coal pile increment model is calculated by the following formula:

[0104] K i =kq i ×kl i ×kh i

[0105] In the above formula, kq i is the coal quality coefficient of the ith coal pile increment model, kl i is the position coefficient of the ith coal pile increment model, kh i is the artificial coefficient of the i-th coal pile increment model.

[0106] In this scheme, the corresponding coal pile increment model is adjusted according to the compaction coefficient, including:

[0107] The vertical coordinates of each coordinate point in the coal pile increment model are adjusted by the compaction coefficient to maintain the plane coordinates of each coordinate point.

[0108] For example, taking the adjustment of a coordinate point in each coal pile incremental model as an example, the coordinate points in each coal pile incremental model may be adjusted in the following manner:

[0109] For a plane coordinate (x1, y1), it is assumed that each coal pile incremental model has a first coordinate point (x1, y1, z1i), a second coordinate point (x1, y1, z2i) and a second coordinate point (x1, y1, z2i). i ), z1 i >z2 i , then on this plane coordinate, the z1 after adjustment of each coal pile increment model i for:

[0110]

[0111] The z2 after adjustment of each coal pile increment model i for:

[0112] z2′ i = z1′ i -(z1 i -z2 i )×K i , i=1...n

[0113] In the above formula, n is the total number of coal pile increment models.

[0114] S304. Update each coal pile incremental compaction model through the coal pile reduction model, and determine the compaction model change of each coal pile incremental compaction model after one consumption of the coal pile.

[0115] Exemplarily, in this step, the implementation method of updating the coal pile incremental compaction model is similar to the content recorded in step S103, and the only difference is that the coal pile incremental model is replaced by the coal pile incremental compaction model.

[0116] Exemplarily, in this solution, the volume of the incremental compaction model of the coal pile before updating is recorded as V1, and the volume of the incremental compaction model of the coal pile after updating is recorded as V2, and the change in the compaction model is the difference between V1 and V2.

[0117] exist Figure 1 On the basis of the beneficial effects of the scheme shown, in this scheme, when the coal pile is compacted, the incremental model of each coal pile is adjusted by the compaction coefficient so that the incremental model of the coal pile can accurately reflect the spatial position of each batch of coal added.

[0118] Figure 4 is another flow chart of the coal pile measurement data processing method in the embodiment, refer to Figure 4 As an implementable solution, the coal pile measurement data processing method can also be:

[0119] S401. Obtain coal pile adding measurement data, and generate multiple coal pile increment models based on the coal pile adding measurement data.

[0120] In this scheme, multiple coal pile incremental models are generated in the following way:

[0121] Determine the number of times the coal is added before the coal pile is consumed, and sequentially obtain the measurement data of the first coal pile before each coal addition and the measurement data of the second coal pile after each coal addition;

[0122] The coal pile increment model after each coal addition is generated in sequence through the corresponding first coal pile measurement data and second coal pile measurement data.

[0123] Exemplarily, taking the generation of a coal pile increment model as an example, the generation of the pile increment model specifically includes:

[0124] The measurement data of the first coal pile is recorded as the first point cloud data, and the measurement data of the second coal pile is recorded as the second point cloud data. In the same plane coordinate, the coordinate point in the first point cloud data is recorded as the first point cloud coordinate point, and the coordinate point in the second point cloud data is recorded as the second point cloud coordinate point;

[0125] Compare each pair of first point cloud coordinate points and second point cloud coordinate points having the same plane coordinates in the first point cloud data and the second point cloud data respectively;

[0126] If, in a pair of first point cloud coordinate points and second point cloud coordinate points, the ordinate of the second point cloud coordinate point has a positive increment relative to the ordinate of the first point cloud coordinate point, then the pair of first point cloud coordinate points and second point cloud coordinate points are added to the incremental model point cloud data set;

[0127] The incremental model of the coal pile after the corresponding coal addition is represented by the incremental model point cloud data set.

[0128] In this scheme, only the first point cloud coordinate point and the second point cloud coordinate point whose longitudinal coordinate has a positive increment relative to the longitudinal coordinate of the first point cloud coordinate point are added to the incremental model point cloud data set. At this time, the coal pile incremental model represented by the incremental model point cloud data set can accurately reflect the spatial position increment of the coal added in each batch, reducing the modeling error of the coal pile incremental model caused by abnormal coordinate point position.

[0129] S402. Obtain coal pile consumption measurement data, and generate a coal pile reduction model based on the coal pile consumption measurement data.

[0130] In this scheme, the coal pile reduction model is generated in the following way:

[0131] Obtaining measurement data of a third coal pile before the coal pile is consumed and measurement data of a fourth coal pile after the coal pile is consumed;

[0132] A coal pile reduction model is generated through the third coal pile data and the fourth coal pile data.

[0133] The third coal pile measurement data is recorded as the third point cloud data, and the fourth coal pile measurement data is recorded as the fourth point cloud data. Under the same plane coordinates, the coordinate points in the third point cloud data are recorded as the third point cloud coordinate points, and the coordinate points in the fourth point cloud data are recorded as the fourth point cloud coordinate points;

[0134] Comparing each pair of third point cloud coordinate points and fourth point cloud coordinate points having the same plane coordinates in the third point cloud data and the fourth point cloud data respectively;

[0135] If, in a pair of the third point cloud coordinate point and the fourth point cloud coordinate point, the ordinate of the fourth point cloud coordinate point has a negative increment relative to the ordinate of the third point cloud coordinate point, then the pair of the third point cloud coordinate point and the fourth point cloud coordinate point are added to the reduced model point cloud data set;

[0136] The coal pile reduction model is represented by a reduction model point cloud data set.

[0137] In this scheme, only the third point cloud coordinate point and the fourth point cloud coordinate point whose longitudinal coordinate has a negative increment relative to the longitudinal coordinate of the third point cloud coordinate point are added to the reduction model point cloud data set. At this time, the coal pile reduction model represented by the reduction model point cloud data set can accurately reflect the spatial position of the consumed part of the coal pile, reducing the modeling error of the coal pile reduction model caused by abnormal coordinate point position.

[0138] S403. Obtain the compaction coefficient corresponding to each coal pile incremental model respectively, adjust the corresponding coal pile incremental model according to the compaction coefficient, and generate a coal pile incremental compaction model.

[0139] S404. Update each coal pile incremental compaction model through the coal pile reduction model, and determine the compaction model change of each coal pile incremental compaction model after one consumption of the coal pile.

[0140] Exemplarily, in this scheme, the coal pile incremental compaction model includes a first envelope surface and a second envelope surface, and the coal pile reduction model includes a third envelope surface and a fourth envelope surface, wherein, in the vertical direction, the first envelope surface is located above the second envelope surface, and the third envelope surface is located below the fourth envelope surface.

[0141] Exemplarily, for a coal pile incremental compaction model, the first envelope surface is composed of point cloud data after the current coal addition selected when generating the coal pile incremental compaction model, and the second envelope surface is composed of point cloud data before the current coal addition selected when generating the coal pile incremental compaction model;

[0142] For the coal pile reduction model, the third envelope surface is composed of the point cloud data after the coal pile is consumed when generating the coal pile reduction model, and the fourth envelope surface is composed of the point cloud data before the coal pile is consumed when generating the coal pile reduction model.

[0143] Exemplarily, the coal pile incremental compaction model may be updated as follows:

[0144] For a coal pile incremental compaction model, determining a first plane overlap region corresponding to a third envelope surface located between the first envelope surface and the second envelope surface;

[0145] In the range corresponding to the first plane overlapping area, the coordinates of the first envelope surface are replaced with the coordinates of the third envelope surface;

[0146] determining a second plane overlapping region corresponding to a third envelope surface located below the second envelope surface;

[0147] Within a range corresponding to the second plane overlapping area, the coordinates of the first envelope surface and the second envelope surface are deleted.

[0148] Exemplarily, the above method can also be applied to updating the coal pile incremental model.

[0149] Exemplarily, in this solution, the implementation method of determining the amount of change in the compaction model is the same as the corresponding content recorded in step S304.

[0150] S405. Obtain the added coal mass data, and determine the remaining mass corresponding to each coal pile incremental compaction model after the coal pile is consumed once.

[0151] Exemplarily, the implementation method of this step is similar to the method described in step S204, and the only difference is that the coal pile incremental model is replaced by the coal pile incremental compaction model.

[0154] The data acquisition module 100 is used to obtain coal pile addition measurement data and coal pile consumption measurement data.

[0155] The model calculation module 200 is used to: generate multiple coal pile incremental models through coal pile addition measurement data, and generate a coal pile reduction model through coal pile consumption measurement data; update each coal pile incremental model through the coal pile reduction model, and determine the incremental model change of each coal pile incremental model after one consumption of the coal pile.

[0156] Exemplarily, the model calculation module 200 may adopt any of the methods described in the first embodiment to update the incremental model of the coal pile, and determine the incremental model change amount of each incremental model of the coal pile.

[0157] In one possible implementation scheme, the data acquisition module 100 can also be used to acquire coal addition quality data. In this case, the model calculation module 200 can also be used to determine the remaining quality corresponding to each coal pile increment model.

[0158] In one possible implementation scheme, the data acquisition module 100 can also be used to obtain the compaction coefficient corresponding to each coal pile incremental model. In this case, the model calculation module 200 can also be used to adjust the corresponding coal pile incremental model according to the compaction coefficient, generate a coal pile incremental compaction model, update each coal pile incremental compaction model, and determine the corresponding compaction model change.
