Description

Technical Field

[0001] The present application relates to the field of ore separation, and in particular to a method, system, electronic equipment and storage medium for processing coal gangue. Background Art

[0002] Gangue is a solid waste formed during the coal mining process. It needs to be separated from coal. Currently, XRT (X-ray Transmission) intelligent sorting machines are commonly used to separate gangue. XRT intelligent sorting machines identify gangue through X-rays. After identifying the gangue on the conveyor belt, the air exhaust gun at the end of the conveyor belt is controlled to spray gas to propel the gangue into flight without spraying gas on the coal. This separates the gangue and coal onto their respective conveyor belts, ultimately achieving the separation of gangue.

[0003] However, when the current XRT intelligent sorting machine sprays gas towards the gangue, due to the difference in quality between the gangues, some gangue will not receive sufficient thrust, causing these gangues to enter the coal conveyor belt, resulting in poor separation effect and even separation failure. Therefore, how to improve the separation effect of gangue and further reduce the gangue in the separated coal has become a problem. Summary of the Invention

Coal and gangue behave differently when X-ray is transmitted, so the gangue can be identified based on the X-ray image. In addition, materials with different densities absorb X-rays to different degrees, so the density of the gangue can be determined based on the X-ray image. The appearance of the gangue recorded in the color image is a series, so the color image can be used to determine the gangue. The contour of the gangue. Due to the irregular shape of the gangue, in order to determine the volume of the gangue as accurately as possible, the volume correction coefficient is determined according to the contour and height value, and then the volume of the gangue is accurately determined according to the height value, contour and volume correction coefficient of the gangue. Then, the mass of the gangue is determined in combination with the density of the gangue. Finally, the appropriate pressure value of the air discharge gun is determined according to the mass of the gangue, so that the gangue can more easily enter the gangue conveyor belt but not easily enter the coal conveyor belt, thereby improving the separation effect.

[0034] Calculating the distance between the trajectory point and the end of the partition plate close to the gas exhaust gun;

[0035] If the distance is less than the preset distance, the pressure value corresponding to the target preset mass interval is increased.

[0036] In another possible implementation, increasing the pressure value corresponding to the target preset mass interval includes:

[0037] determining, based on the video information, a velocity of the coal gangue when the gangue is located directly above one end of the partition plate close to the gas lance;

Coal and gangue behave differently when X-rays are transmitted, so gangue can be identified based on the X-ray image, and materials of different densities absorb X-rays to different degrees.

[0090] After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.

[0091] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0092] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document, unless otherwise specified, generally indicates an "or" relationship between the related objects.

[0093] The embodiment of the present application provides a method for processing coal gangue, which is performed by an electronic device, which can be a server or a terminal device, wherein the server can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, which is not limited in the embodiment of the present application. Figure 1 As shown, the method includes step S101, step S102, step S103, step S104, step S105 and step S106, wherein,

[0094] S101, obtaining an X-ray image, a color image and a height value of the coal gangue on the conveyor belt of the sorting machine.

[0095] In the embodiment of the present application, an XRT intelligent sorting machine is equipped with an X-ray emitting device, a camera device, and a laser rangefinder above the conveyor belt. These devices are all connected to the electronic device via wires. The X-ray emitting device generates an X-ray image of the gangue based on the emitted X-rays and sends it to the electronic device. The camera device captures a color image of the gangue and sends it to the electronic device. The laser rangefinder emits a laser toward the gangue to obtain the distance from the laser rangefinder to the gangue. The electronic device stores a preset distance from the laser rangefinder to the conveyor belt. The height of the gangue can be calculated by subtracting the distance from the laser rangefinder to the gangue from this preset distance.

[0096] S102, determining the density of the gangue based on the X-ray image, and determining the contour of the gangue based on the color image.

[0097] In this embodiment of the present application, the electronic device performs grayscale conversion on the X-ray image to obtain a grayscale image of the gangue, and determines the density of the gangue by calculating the limescale value of the gangue. In other embodiments, the X-ray emission device can calculate the density of the gangue by measuring the change in X-ray intensity before and after passing through the gangue, and then transmit this density to the electronic device. The electronic device performs denoising on the color image, performs grayscale conversion on the denoised color image to obtain a grayscale image, and then performs edge detection on the grayscale image to obtain the outline of the gangue.

[0098] S103: Determine a volume correction coefficient based on the height value and the outline.

[0099] In the present embodiment, the gangue's bottom area can be represented by its contour, and its height can be used as its height. The volume of the gangue can then be calculated using a volume calculation formula. However, due to the irregular shape of the gangue, the volume calculated using this method can result in significant errors. Therefore, the gangue's height and contour are first analyzed to determine a volume correction factor. This correction factor allows for a more accurate calculation of the gangue's volume in subsequent calculations.

[0100] S104: Determine the volume of the gangue based on the height value, the profile, and the volume correction coefficient.

[0101] In the embodiment of the present application, after the electronic device determines the volume correction coefficient, the volume of the gangue can be determined by multiplying the contour by the height value and then by the volume correction coefficient.

[0102] S105: Determine the mass of the coal gangue based on the volume and density.

[0103] In the embodiment of the present application, after the electronic device determines the volume and density of the gangue, the mass of the gangue can be determined by multiplying the volume by the density.

[0104] S106: Determine the pressure value of the air lance when pushing the gangue based on the mass.

[0105] In the embodiment of the present application, the air lance is an important part of the XRT separator. It is installed at the end of the conveyor belt, usually with a width equal to the conveyor belt, and is used to spray high-speed gas to separate materials. After the electronic equipment determines the mass of the coal gangue, it can determine the appropriate pressure value required by the air lance to push the coal gangue based on the mass. The greater the mass, the greater the required pressure value, and vice versa. By performing targeted calculations on the pressure value of the air lance according to the mass of each coal gangue, each coal gangue can be more easily flown into the coal gangue conveyor belt, thereby improving the separation effect.

[0106] In a possible implementation of the embodiment of the present application, the volume correction coefficient is determined based on the height value and the profile in step S103, which specifically includes step S1031 (not shown in the figure), step S1032 (not shown in the figure), step S1033 (not shown in the figure), and step S1034 (not shown in the figure), wherein:

[0107] S1031, calculating the similarity between the contour and each gangue contour in the preset contour library, and determining the first target contour with the highest similarity.

[0108] Among them, each gangue contour in the preset contour library corresponds to a volume correction coefficient.

[0109] In the embodiment of the present application, the electronic device can convert the outline of the gangue and each gangue outline in the preset outline library into an image. Then, the cosine distance between the outline of the gangue and each outline in the preset outline library is calculated to determine the similarity. After the electronic device calculates the similarity of each gangue outline in the preset outline library, it sorts the similarities from large to small to determine the first target outline with the highest similarity. The volume correction coefficient of the gangue corresponding to each outline in the preset outline library is obtained by the staff after measuring the actual volume. The staff first multiplies the outline by the height value to obtain the volume with a larger error, and then divides the actual volume by the volume with a larger error to obtain the volume correction coefficient.

[0110] S1032: Determine the area of the contour and the ratio of the area to the height.

[0111] In the embodiment of the present application, the electronic device can calculate the number of pixels within the contour and then use the number of pixels to represent the area of the contour. After the electronic device determines the area of the contour, it divides the area by the height of the gangue to obtain a ratio.

[0112] S1033: Search for a second target contour that is consistent with the ratio from a preset contour library.

[0113] Among them, the ratio of the area corresponding to the contour of each gangue contour in the preset contour library to the corresponding gangue height value.

[0114] In this embodiment of the present application, each gangue profile in the preset profile library corresponds to a ratio of the area to height of a corresponding real gangue profile. Based on the ratio corresponding to the gangue, the electronic device searches the preset profile library for a second target profile with a consistent ratio. A consistent ratio indicates that the gangue shapes are likely similar, and the corresponding volume correction coefficients are also similar. In other words, the volume correction coefficient of the gangue with the consistent ratio is close to the volume correction coefficient of the current gangue.

[0115] S1034: Determine a volume correction coefficient of the coal gangue based on the volume correction coefficient of the first target profile and the volume correction coefficient of the second target profile.

[0116] In the embodiment of the present application, the volume correction coefficient of the first target profile and the volume correction coefficient of the second target profile can both, to a certain extent, characterize the volume correction coefficient of the current gangue. Therefore, the electronic device determines a more accurate volume correction coefficient representing the current gangue based on the volume correction coefficients of the first target profile and the second target profile.

[0117] In a possible implementation of the embodiment of the present application, the volume correction coefficient of the gangue is determined based on the volume correction coefficient of the first target profile and the volume correction coefficient of the second target profile in step S1034, specifically including step Sa (not shown in the figure), step Sb (not shown in the figure), step Sc (not shown in the figure), and step Sd (not shown in the figure), wherein:

[0118] Sa, calculate the absolute value of the difference between the volume correction coefficient of the first target profile and the volume correction coefficient of the second target profile.

[0119] In the embodiment of the present application, the electronic device subtracts the volume correction coefficient of the second target profile from the volume correction coefficient of the first target profile to obtain the difference in volume correction coefficients, and then takes the absolute value of the difference to obtain the absolute value of the difference.

[0120] Sb: If the absolute value of the difference is greater than the preset threshold, a plurality of third target contours whose contour similarities reach the preset similarity threshold are determined from the preset contour library.

[0121] For the embodiment of the present application, if the absolute value of the difference is greater than the preset threshold, it means that the gap between the volume correction coefficient of the first target profile and the volume correction coefficient of the second target profile is large. The accuracy of determining the volume correction coefficient of the current coal gangue only by these two volume correction coefficients is low. Therefore, the electronic device determines a plurality of third target profiles from the preset profile library whose profile similarity reaches a preset similarity threshold. The preset similarity threshold serves as a demarcation point for whether the profile similarity is high or not. Reaching the preset similarity threshold indicates that the profile is close to the current coal gangue. The volume correction coefficient of the current coal gangue is calculated more accurately by combining the volume correction coefficients of these third target profiles that reach the preset similarity threshold. If the absolute value of the difference is not greater than the preset threshold, it means that the volume correction coefficient of the first target profile and the volume correction coefficient of the second target profile are relatively close, and the volume correction coefficient of the current coal gangue can be determined more accurately by these two volume correction coefficients.

[0122] Sc, calculate a first average value of the volume correction coefficients of the plurality of third target profiles.

[0123] In the embodiment of the present application, the electronic device calculates the first average value of the volume correction coefficients of all third target profiles through the average value calculation formula, and the first average value is used to more accurately characterize the volume correction coefficients of all third target profiles as a whole.

[0124] Sd, calculates a second average value of the first average value and the volume correction coefficient of the second target profile.

[0125] The second average value represents the volume correction coefficient of the coal gangue.

[0126] For the embodiment of the present application, after the electronic device calculates the first average value, it calculates the second average value of the volume correction coefficient of the first average value and the second target profile through the average value calculation formula. The second average value combines the volume correction coefficients of more coal gangues with similar properties to the current coal gangue, so that the second average value is used to characterize the volume correction coefficient of the current coal gangue more accurately.

[0127] In a possible implementation of the embodiment of the present application, the method for determining a preset threshold further includes steps 1 and 2, wherein:

[0128] Step 1: Calculate the sum of the volume correction coefficient of the first target profile and the volume correction coefficient of the second target profile.

[0129] Step 2: Multiply the coefficient sum by the preset ratio to obtain the preset threshold.

[0130] In the embodiment of the present application, the electronic device sums the volume correction coefficient of the first target profile and the volume correction coefficient of the second target profile to obtain a coefficient sum, and the preset ratio can be one-third, one-quarter, etc. Taking one-third as an example, the electronic device multiplies the obtained coefficient sum by one-third to obtain the preset threshold value.

[0131] In a possible implementation of the embodiment of the present application, in S106, the pressure value of the gas discharge gun when pushing the gangue is determined based on the mass, specifically including step S1061 (not shown in the figure) and step S1062 (not shown in the figure), wherein:

[0132] S1061 : Determine a target preset quality interval of quality from a plurality of preset quality intervals.

[0133] Each preset mass interval corresponds to a preset pressure value.

[0134] S1062: Determine a preset pressure value corresponding to the target preset mass range as the pressure value for pushing the coal gangue.

[0135] In the embodiment of the present application, a plurality of preset mass intervals are stored in the local storage medium within the electronic device. The preset pressure value corresponding to each preset mass interval is obtained by the staff through multiple experiments or calculations. The electronic staff can set the range of the preset mass interval through a visual operation interface and determine the correspondence between each preset mass interval and the preset pressure value. After the electronic device determines the current mass of the gangue, it compares it with each preset mass interval respectively, thereby determining the target preset mass interval in which the current gangue mass lies. The preset pressure value corresponding to the target preset mass interval is then used as the pressure value for the air exhaust gun to push the gangue.

[0136] In a possible implementation of the embodiment of the present application, a separator is provided in the separator for screening coal blocks and coal gangue, and the method further includes step S107 (not shown in the figure), step S108 (not shown in the figure), step S109 (not shown in the figure), step S110 (not shown in the figure), and step S111 (not shown in the figure), wherein step S107 may be performed after step S106, wherein,

[0137] S107, when it is detected that the air discharge gun releases pressure to the gangue, video information of the gangue flying is obtained.

[0138] In this embodiment of the present application, the electronic device is connected to the air blast gun via a wire. When the air blast gun releases pressure, it outputs a signal to the electronic device. Upon receiving the signal, the electronic device detects the release of pressure from the air blast gun on the gangue. A camera device is also installed within the XRT intelligent sorting machine to capture video footage of the gangue passing through the air blast gun from the side.

[0139] S108, determining the movement trajectory of the coal gangue based on the video information.

[0140] In the embodiment of the present application, the electronic device performs feature recognition on the video information to identify the coal gangue, and then performs dynamic tracking on the coal gangue to generate the movement trajectory of the coal gangue.

[0141] S109, determining from the motion trajectory a trajectory point where the gangue is located directly above one end of the partition plate close to the gas lance.

[0142] In the embodiments of the present application, the partition plate is typically positioned at an angle, with the end of the partition plate near the gas lance higher than the other end. The partition plate divides the area outside the end of the conveyor belt into two areas: the upper area is where the gangue passes, and the lower area is where the coal passes. The electronic device identifies the end of the partition plate near the gas lance from the video information and then draws a vertical extension line upward from the end of the partition plate near the gas lance. The point where the vertical extension line intersects the motion trajectory is the point on the trajectory where the gangue is located directly above the end of the partition plate near the gas lance.

[0143] S110, calculating the distance between the trajectory point and the end of the partition plate close to the gas exhaust gun.

[0144] In this embodiment of the present application, the electronic device can calculate the number of pixels in the numerical direction between the trajectory point and the end of the partition plate near the gas lance, and use the number of pixels to represent the distance. The electronic device can also map the motion trajectory and the end of the partition plate near the gas lance into a preset plane rectangular coordinate system, then determine the coordinates of the trajectory point and the end of the partition plate near the gas lance, and calculate the distance between the trajectory point and the end of the partition plate near the gas lance using the distance formula between the two points.

[0145] S111 , if the distance is less than the preset distance, increasing the pressure value corresponding to the target preset mass range.

[0146] In this embodiment of the present application, a preset distance serves as the demarcation point for determining whether gangue is too close to the divider plate. If the distance is less than the preset distance, there is a certain risk that the gangue will collide with the divider plate and enter the coal area below the divider plate. Therefore, the electronic device increases the pressure value corresponding to the target preset mass range of the current gangue. This allows the air discharge gun to apply higher pressure when separating gangue of the same mass in subsequent operations, making it less likely that the gangue will enter under the divider plate. If the distance reaches the preset distance, the risk of gangue colliding with the divider plate is low, and there is no need to increase the pressure value corresponding to the target preset mass range.

[0147] Furthermore, the electronic device can separate each frame from the video of the gangue's flight, determine the gangue's outline within each frame, and then determine the number of revolutions the gangue has made based on the outline from the video. The rotational speed of the gangue during flight is then calculated based on the flight time. The greater the rotational speed, the more likely it is that the force applied by the gas from the air lance on the gangue is not centered. The thrust applied may be located upward or downward, causing the gangue to deflect during flight and, in turn, to rotate. This upward or downward thrust application may result in insufficient horizontal force components, leading to abnormalities in the gangue's speed and direction, potentially preventing the gangue from entering the gangue conveyor belt. Therefore, the electronic device can combine distance and gangue rotational speed for a comprehensive analysis to increase the pressure value corresponding to the target preset mass range, thereby ensuring that the pressure value is more effective in propelling the gangue. Therefore, the staff can set the coefficients corresponding to the distance and the rotation speed. When the distance is less than the preset distance, the electronic device performs a weighted calculation based on the distance, the rotation speed and the corresponding coefficients to obtain a correction score. The electronic device can increase the pressure value based on the score. For example, the electronic device can directly use the current pressure value plus the correction analysis to obtain the increased pressure value, or determine the preset score range where the correction score is located. Each preset score range corresponds to a pressure correction value, and the current pressure value is added to the pressure correction value of the preset score range to obtain the increased pressure value.

[0148] Furthermore, the electronic equipment can also correct the time when the gas gun ejects gas according to the flight trajectory of the coal gangue. If the flight trajectory is a high parabola, it means that the gas is ejected too early, causing the gas to act on the lower position of the coal gangue. Therefore, the time of gas ejection is corrected backward. If the flight trajectory is directed obliquely downward, it means that the gas is ejected too late, causing the gas to act on the upper position of the coal gangue. Therefore, the time of gas ejection is corrected forward.

[0149] In a possible implementation of the embodiment of the present application, increasing the pressure value corresponding to the target preset mass interval in step S111 specifically includes step S1 (not shown in the figure), step S2 (not shown in the figure), step S3 (not shown in the figure), and step S4 (not shown in the figure), wherein:

[0150] S1, determining the velocity of the gangue when it is located just above the partition plate near one end of the gas lance based on the video information.

[0151] In the embodiments of the present application, the electronic device first decomposes the video information into consecutive frame images. This can be accomplished using tools such as OpenCV. Objects are then identified using object detection algorithms (such as YOLO and SSD), and tracking algorithms (such as KCF and SORT) are used to track the object's position changes between frames. Displacement is then calculated based on the object's coordinate changes between frames. Given the frame rate of the video information, the time interval can be determined. Finally, the velocity of the gangue when it is directly above the partition plate near the end of the gas lance can be calculated based on the displacement and time interval.

[0152] S2, determining the movement state score of the gangue based on the speed, distance and their corresponding coefficients.

[0153] For the embodiment of the present application, the greater the speed of the gangue when it is located directly above one end of the partition plate close to the gas discharge gun, the more stable its flight is, and the less likely it is to enter the coal space below the partition plate. Conversely, the easier it is to enter the coal space, the more likely the separation will fail. Similarly, the greater the distance, the less likely the gangue is to enter the coal space below the partition plate. Conversely, the smaller the distance, the easier it is for the gangue to enter the coal space below the partition plate, resulting in separation failure. That is, speed and distance are both key factors affecting the motion state of gangue during separation, and the degree of influence on the motion state is different. Therefore, the staff can set corresponding coefficients for speed and distance and store them in the local storage medium in the electronic device. After the electronic device determines the speed and distance, it calls the corresponding coefficients to perform weighted calculation to obtain a motion state score. After calculating the motion state score, it is convenient to subsequently calculate the increased pressure value.

[0154] S3, obtaining a pressure increase value based on the motion state score multiplied by a preset proportional coefficient.

[0155] In the embodiment of the present application, a preset proportional coefficient is used to calculate the pressure increase value, which can also be set by the staff and modified and adjusted according to actual conditions and needs. The electronic device multiplies the motion state score by the preset proportional coefficient to obtain the pressure increase value.

[0156] S4, determining the sum of the pressure increase value and the pressure values corresponding to the target preset mass range.

[0157] The sum represents the increased pressure value corresponding to the target preset mass range.

[0158] In this embodiment of the present application, after the electronic device determines the pressure increase, it adds the pressure increase value to the pressure value corresponding to the target preset mass range to calculate a sum. This sum is the increased pressure value corresponding to the target preset mass range. The pressure increase value is determined based on the movement of the gangue above the separator plate near one end of the gas discharge gun. This prevents the gangue from entering the coal space below the separator plate when the gas discharge gun subsequently separates the same mass of gangue, thereby improving the subsequent separation effect.

[0159] The above embodiment introduces a gangue processing method from the perspective of method flow, and the following embodiment introduces a gangue processing system 20 from the perspective of virtual modules or virtual units. Please refer to the following embodiment for details.

Coal and coal gangue behave differently when X-rays are transmitted, so the coal gangue can be identified based on the X-ray image, and materials of different densities absorb X-rays to different degrees, so the first determination module 202 can determine the density of the coal gangue based on the X-ray image. The appearance of the coal gangue recorded in the color image is a series, so the first determination module 202 can determine the coal gangue based on the color image. The contour of the gangue is determined. Since the shape of the gangue is irregular, in order to determine the volume of the gangue as accurately as possible, the second determination module 203 determines the volume correction coefficient based on the contour and height value. Then, the third determination module 204 accurately determines the volume of the gangue based on the height value, contour and volume correction coefficient of the gangue. Then, the fourth determination module 205 determines the mass of the gangue based on the density of the gangue. Finally, the fifth determination module 206 determines the appropriate pressure value of the gas discharge gun based on the mass of the gangue, so that the gangue can more easily enter the gangue conveyor belt but not easily enter the coal conveyor belt, thereby improving the separation effect.
