Description

Technical Field

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

[0002] Coal gangue is a solid waste formed during coal mining. It is necessary to separate coal gangue from coal. Currently, an XRT (X-ray Transmission) intelligent separator is usually used to separate coal gangue. The XRT intelligent separator identifies coal gangue through X-ray. After identifying the coal gangue on the conveyor belt, at the end of the conveyor belt, it controls the air ejection gun to eject gas to push the coal gangue to fly, and does not eject gas to the coal, so as to separate the coal gangue and coal onto their respective corresponding conveyor belts, and finally achieve the separation of coal gangue.

[0003] However, when the current XRT intelligent separator ejects gas to the coal gangue, due to the difference in mass between the coal gangue, some coal gangue will receive insufficient thrust, resulting in these coal gangue entering the coal conveyor belt, leading to a deterioration of the separation effect and separation failure. Therefore, how to improve the separation effect of coal gangue and further reduce the coal gangue in the separated coal has become a problem. Summary of the Invention

[0004] In order to improve the separation effect of coal gangue and further reduce the coal gangue in the separated coal, the present application provides a coal gangue treatment method, system, electronic device and storage medium.

[0006] By adopting the above technical solution, X-ray images, color images and height values of coal gangue on the conveyor belt of the separator are obtained, which facilitates more accurately determining the density, contour, volume, etc. of the coal gangue in the subsequent process. Coal and coal gangue have different performances during X-ray transmission. Therefore, coal gangue can be identified based on the X-ray image. Moreover, substances with different densities have different absorption degrees of X-rays. Therefore, the density of the coal gangue can be determined based on the X-ray image. The color image records a series of lengths, etc. of the coal gangue. Therefore, the contour of the coal gangue can be determined based on the color image. Since the shape of the coal gangue is irregular, in order to determine the volume of the coal gangue as accurately as possible, a volume correction coefficient is determined based on the contour and height value, and then the volume of the coal gangue is accurately determined according to the height value, contour and volume correction coefficient of the coal gangue. Then, the mass of the coal gangue is determined by combining the density of the coal gangue. Finally, the appropriate pressure value of the air exhaust gun is determined according to the mass of the coal gangue, so that the coal gangue can enter the coal gangue conveyor belt more easily and is not easy to enter the coal conveyor belt, thereby improving the separation effect.

[0031] The embodiment of the present application provides a coal gangue treatment method, which is executed by an electronic device. The electronic device can be a server or a terminal device. Among them, 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 notebook computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected through wired or wireless communication methods, and the embodiments of the present application do not limit this here. As Figure 1 shown, the method includes steps S101, S102, S103, S104, S105, and S106, where S101. Obtain the X-ray image, color image, and height value of the coal gangue on the conveyor belt of the separator.

[0032] For the embodiments of the present application, an X-ray emitting device, a camera device, a laser rangefinder, and other devices are provided above the conveyor belt of the XRT intelligent separator. These devices are all connected to the electronic device through wires. The X-ray emitting device generates an X-ray image of the coal gangue according to the emitted X-rays and sends it to the electronic device. The camera device collects the color image of the coal gangue and sends it to the electronic device. The laser rangefinder emits laser light towards the coal gangue to obtain the distance from the laser rangefinder to the coal gangue. The preset distance from the laser rangefinder to the conveyor belt is stored in the electronic device. Subtracting the distance from the laser rangefinder to the coal gangue from the preset distance can calculate the height value of the coal gangue.

[0033] S102. Determine the density of the coal gangue based on the X-ray image and determine the contour of the coal gangue based on the color image.

[0034] For the embodiments of the present application, the electronic device performs gray-scale transformation on the X-ray image to obtain a gray-scale image of the coal gangue, and determines the density of the coal gangue by calculating the size of the gray-scale value of the coal gangue. In other embodiments, the X-ray emitting device can calculate the density of the coal gangue by measuring the intensity change of the X-rays before and after passing through the coal gangue, and then send the density to the electronic device. The electronic device performs denoising processing on the color image, performs gray-scale transformation on the denoised color image to obtain a gray-scale image, and then performs edge detection on the gray-scale image to obtain the contour of the coal gangue.

[0035] S103. Determine the volume correction coefficient based on the height value and the contour.

[0036] For the embodiments of the present application, the contour can be used to represent the bottom area of the coal gangue, and the height value is used as the height of the coal gangue. Then, the volume of the coal gangue is calculated using the volume calculation formula. However, since the shape of the coal gangue is irregular, the volume calculated by this method has a large error. Therefore, the height value and the contour of the coal gangue are first analyzed to determine the volume correction coefficient, and a more accurate volume of the coal gangue can be obtained through the volume correction coefficient in subsequent calculations.

[0037] S104. Determine the volume of the coal gangue based on the height value, the contour, and the volume correction coefficient.

[0038] For the embodiments of the present application, after the electronic device determines the volume correction coefficient, multiplying the contour by the height value and then by the volume correction coefficient can determine the volume of the coal gangue.

[0039] S105. Determine the mass of the coal gangue based on the volume and the density.

[0040] For the embodiment of the present application, after the electronic device determines the volume and density of the coal gangue, the mass of the coal gangue can be determined by multiplying the volume by the density.

[0041] S106, determining the pressure value of the air discharge gun when pushing the coal gangue based on the mass.

[0042] For the embodiment of the present application, the air discharge gun is an important part of the XRT sorter, which is arranged at the end of the transmission belt, usually equal to the width of the transmission 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 discharge gun when pushing the coal gangue according to the mass. The greater the mass, the greater the required pressure value, and vice versa. The pressure value of the air discharge gun is calculated specifically according to the mass of each coal gangue, so that each coal gangue can fly more easily into the coal gangue conveyor belt, thereby improving the separation effect.

[0043] 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: 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.

[0044] Among them, each gangue contour in the preset contour library corresponds to a volume correction coefficient.

[0045] For the embodiment of the present application, the electronic device can convert the contour of the gangue and each contour of the gangue in the preset contour library into an image. Then, the cosine distance between the contour of the gangue and each contour in the preset contour library is calculated to determine the similarity. After the electronic device calculates the similarity of each contour of the gangue in the preset contour library, the similarities are sorted from large to small to determine the first target contour with the highest similarity. The volume correction coefficient of the gangue corresponding to each contour in the preset contour library is obtained by the staff after measuring the actual volume, first multiplying the contour by the height value to obtain the volume with a larger error, and then dividing the actual volume by the volume with a larger error to obtain the volume correction coefficient.

[0046] S1032, determine the area of ​​the contour, and determine the ratio of the area to the height value.

[0047] For the embodiment of the present application, the electronic device can calculate the number of pixels in 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.

[0048] S1033. Search for a second target contour in the preset contour library that is consistent with the ratio.

[0049] Among them, for each coal gangue contour in the preset contour library, there is a ratio of the area of the contour to the corresponding coal gangue height value.

[0050] For the embodiments of the present application, each coal gangue contour in the preset contour library corresponds to a ratio of the area of the contour of the corresponding real coal gangue to the height value. The electronic device searches for a second target contour with a consistent ratio in the preset contour library according to the ratio corresponding to the coal gangue. A consistent ratio indicates that the shapes of the coal gangues may be relatively close, and the corresponding volume correction factors are also relatively close, that is, the volume correction factor of the coal gangue with a consistent ratio is relatively close to the volume correction factor of the current coal gangue.

[0051] S1034. Determine the volume correction factor of the coal gangue based on the volume correction factor of the first target contour and the volume correction factor of the second target contour.

[0052] For the embodiments of the present application, the volume correction factor of the first target contour and the volume correction factor of the second target contour can both characterize the volume correction factor of the current coal gangue to a certain extent. Therefore, the electronic device determines a more accurate volume correction factor representing the current coal gangue according to the volume correction factor of the first target contour and the volume correction factor of the second target contour.

[0053] In a possible implementation manner of the embodiments of the present application, in step S1034, determining the volume correction factor of the coal gangue based on the volume correction factor of the first target contour and the volume correction factor of the second target contour specifically includes 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), where Sa. Calculate the absolute value of the difference between the volume correction factor of the first target contour and the volume correction factor of the second target contour.

[0054] For the embodiments of the present application, the electronic device subtracts the volume correction factor of the second target contour from the volume correction factor of the first target contour to obtain the difference of the volume correction factor, and then takes the absolute value of the difference to obtain the absolute value of the difference.

[0055] Sb. If the absolute value of the difference is greater than the preset threshold, determine multiple third target contours in the preset contour library whose contour similarity reaches the preset similarity threshold.

[0056] For the embodiments of the present application, if the absolute value of the difference is greater than the preset threshold, it indicates that there is a large gap between the volume correction coefficient of the first target contour and the volume correction coefficient of the second target contour. It is less accurate to determine the volume correction coefficient of the current coal gangue only through these two volume correction coefficients. Therefore, the electronic device determines multiple third target contours from the preset contour library whose similarity to the contour reaches the preset similarity threshold. The preset similarity threshold serves as a demarcation point for whether the similarity of the contour is high. Reaching the preset similarity threshold indicates a high degree of proximity to the contour of the current coal gangue. Combining the volume correction coefficients of these third target contours that reach the preset similarity threshold to calculate the volume correction coefficient of the current coal gangue is more accurate. If the absolute value of the difference is not greater than the preset threshold, it indicates that the volume correction coefficient of the first target contour is relatively close to the volume correction coefficient of the second target contour. Through these two volume correction coefficients, the volume correction coefficient of the current coal gangue can be determined more accurately.

[0057] Sc, calculate the first average value of the volume correction coefficients of multiple third target contours.

[0058] For the embodiments of the present application, the electronic device calculates the first average value of the volume correction coefficients of all third target contours through the average value calculation formula, and the first average value more accurately represents the volume correction coefficients of all third target contours as a whole.

[0059] Sd, calculate the second average value of the first average value and the volume correction coefficient of the second target contour.

[0060] Among them, the second average value represents the volume correction coefficient of the coal gangue.

[0061] For the embodiments of the present application, after the electronic device calculates the first average value, it then calculates the second average value of the first average value and the volume correction coefficient of the second target contour through the average value calculation formula. The second average value combines the volume correction coefficients of more coal gangues with similar attributes to the current coal gangue, so that it is more accurate to represent the volume correction coefficient of the current coal gangue with this second average value.

[0062] A possible implementation manner of the embodiments of the present application is to determine the preset threshold. The method further includes Step 1 and Step 2, where Step 1, calculate the sum of the coefficients of the volume correction coefficient of the first target contour and the volume correction coefficient of the second target contour.

[0063] Step 2, multiply the sum of the coefficients by the preset ratio to obtain the preset threshold.

[0064] For the embodiments of the present application, the electronic device sums up the volume correction coefficients of the first target contour and the second target contour to obtain the coefficient sum. The preset ratio can be one-third, one-fourth, etc. Taking one-third as an example, the electronic device multiplies the obtained coefficient sum by one-third to obtain the preset threshold value.

[0065] In a possible implementation manner of the embodiments of the present application, determining the pressure value when the air ejector gun pushes the coal gangue based on the mass in S106 specifically includes step S1061 (not shown in the figure) and step S1062 (not shown in the figure), where S1061, determining the target preset mass interval where the mass is located from multiple preset mass intervals.

[0066] Wherein, each preset mass interval corresponds to a preset pressure value.

[0067] S1062, determining the preset pressure value corresponding to the target preset mass interval as the pressure value for pushing the coal gangue.

[0068] For the embodiments of the present application, multiple preset mass intervals are stored in the local storage medium inside 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 the visual operation interface and determine the corresponding relationship between each preset mass interval and the preset pressure value. After the electronic device determines the mass of the current coal gangue, it compares it with each preset mass interval respectively, so as to determine the target preset mass interval where the current coal gangue mass is located, and then uses the preset pressure value corresponding to the target preset mass interval as the pressure value for the air ejector gun to push the coal gangue.

[0069] In a possible implementation manner of the embodiments of the present application, a partition plate for screening coal blocks and coal gangue is provided inside the separator. 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), where step S107 can be executed after step S106, where S107, when it is detected that the air ejector gun releases pressure to the coal gangue, acquiring video information of the flight of the coal gangue.

[0070] For the embodiments of the present application, the electronic device is connected to the air ejector gun through a wire. When the air ejector gun releases pressure, it outputs a signal to the electronic device. After receiving the signal, the electronic device can detect that the air ejector gun releases pressure to the coal gangue. A camera device is also installed inside the XRT intelligent separator for collecting video information of the coal gangue passing by the air ejector gun from the side.

[0071] S108. Determine the movement trajectory of coal gangue based on video information.

[0072] For the embodiments of this application, the electronic device performs feature recognition on the video information to identify the coal gangue, and then uses a dynamic tracker for the coal gangue to generate the movement trajectory of the coal gangue.

[0073] S109. Determine the trajectory point where the coal gangue is directly above the end of the partition plate near the air ejector gun from the movement trajectory.

[0074] For the embodiments of this application, the partition plate is usually placed obliquely, with the end of the partition plate near the air ejector gun 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 the area through which the coal gangue passes, and the lower area is the area through which the coal passes. The electronic device identifies the end of the partition plate near the air ejector gun from the video information, and then makes a vertical extension line upward at the end of the partition plate near the air ejector gun. The point where the vertical extension line intersects the movement trajectory is the trajectory point where the coal gangue is directly above the end of the partition plate near the air ejector gun.

[0075] S110. Calculate the distance between the trajectory point and the end of the partition plate near the air ejector gun.

[0076] For the embodiments of this 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 air ejector gun, and use the number of pixels to characterize the distance. The electronic device can also map the movement trajectory and the end of the partition plate near the air ejector gun to a preset plane rectangular coordinate system, and then determine the coordinate points of the trajectory point and the end of the partition plate near the air ejector gun, and calculate the distance between the trajectory point and the end of the partition plate near the air ejector gun using the distance formula between two points.

[0077] S111. If the distance is less than the preset distance, increase the pressure value corresponding to the target preset mass interval.

[0078] For the embodiments of this application, the preset distance is used as the demarcation point for whether the coal gangue is too close to the partition plate. If the distance is less than the preset distance, it means that the coal gangue has a certain risk of colliding with the partition plate and then entering the coal area below the partition plate. Therefore, the electronic device increases the pressure value corresponding to the target preset mass interval where the current coal gangue is located, so that when separating coal gangue of the same mass in the subsequent process, the air ejector gun can have a greater pressure, making it more difficult for the coal gangue to enter below the partition plate. If the distance reaches the preset distance, it means that the risk of the coal gangue colliding with the partition plate is low, and there is no need to increase the pressure value corresponding to the target preset mass interval.

[0079] Further, the electronic device can also separate each frame of image from the video information of the coal gangue flight, determine the contour of the coal gangue in each frame of image, then determine the number of rotation circles of the coal gangue from the video information according to the contour, and then calculate the rotation speed of the coal gangue during flight according to the flight time. The greater the rotation speed, it indicates that the position of the force exerted by the gas ejected from the air ejector gun on the coal gangue is not in the middle position, and the position where the thrust is applied may be too high or too low, resulting in the deflection of the coal gangue during flight, and then causing rotation. The position where the thrust is applied being too high or too low may result in insufficient horizontal component force, and then cause abnormalities in the speed magnitude and direction of the coal gangue, and the coal gangue may not be able to enter the coal gangue conveyor belt. Therefore, the electronic device can comprehensively analyze the distance and the rotation speed of the coal gangue to increase the pressure value corresponding to the target preset mass range, so that the pressure value can better push the coal gangue. Therefore, the staff can set the coefficients corresponding to the distance and the rotation speed respectively. When the distance is less than the preset distance, the electronic device performs weighted calculation based on the distance, the rotation speed, and their respective corresponding coefficients to obtain a correction score, and the electronic device can increase the pressure value according to this score. For example, the electronic device can directly add the current pressure value with 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 add the current pressure value with the pressure correction value of the preset score range where it is located to obtain the increased pressure value.

[0080] Furthermore, the electronic device can also correct the moment when the air ejector gun ejects gas according to the flight trajectory of the coal gangue. If the flight trajectory is a high parabola, it indicates that the moment of ejecting gas is too early, resulting in the gas acting on the lower position of the coal gangue. Therefore, the moment of ejecting gas is corrected to be later. If the flight trajectory is towards the lower oblique direction, it indicates that the moment of ejecting gas is too late, resulting in the gas acting on the upper position of the coal gangue. Therefore, the moment of ejecting gas is corrected to be earlier.

[0081] In a possible implementation manner of the embodiment of the present application, increasing the pressure value corresponding to the target preset mass range 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), where S1, determining the speed of the coal gangue when it is directly above the end of the partition plate close to the air ejector gun based on the video information.

[0082] For the embodiments of the present application, the electronic device first decomposes the video information into consecutive frame images, and this operation can be specifically completed using tools such as OpenCV. Then, object detection algorithms (such as YOLO, SSD, etc.) are used to identify objects, and tracking algorithms (such as KCF, SORT, etc.) are used to track the position changes of the objects between frames. Next, the displacement is calculated based on the coordinate changes of the objects between frames, and since the frame rate of the video information is known, the time interval can be determined. Finally, based on the displacement and the time interval, the speed of the coal gangue when it is directly above the end of the partition plate close to the air ejector gun can be calculated.

[0083] S2. Determine the motion state score of the coal gangue based on the speed, distance, and their respective corresponding coefficients.

[0084] For the embodiments of the present application, the greater the speed of the coal gangue when it is directly above the end of the partition plate close to the air ejector gun, the more stable its flight, and the less likely it is to enter the coal space below the partition plate. Conversely, it is more likely to enter the coal space and the separation fails. Similarly, the greater the distance, the less likely the coal gangue is to enter the coal space below the partition plate. Conversely, the smaller the distance, the more likely the coal gangue is to enter the coal space below the partition plate, resulting in separation failure. That is, both speed and distance are key factors affecting the motion state of the coal gangue during separation, and their degrees of influence on the motion state are different. Therefore, the staff can set their respective 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 their respective corresponding coefficients for weighted calculation to obtain the motion state score. Calculating the motion state score facilitates the subsequent calculation of the increased pressure value.

[0085] S3. Obtain the pressure increase value by multiplying the motion state score by a preset proportional coefficient.

[0086] For the embodiments of the present application, the preset proportional coefficient is used to calculate the pressure increase value, which can also be set by the staff, and this preset proportional coefficient can be modified and adjusted according to the actual situation and requirements. The electronic device multiplies the motion state score by the preset proportional coefficient to obtain the pressure increase value.

[0087] S4. Determine the sum of the pressure increase value and the pressure value corresponding to the target preset mass range.

[0088] Among them, the sum represents the increased pressure value corresponding to the target preset mass range.

[0089] For the embodiments of the present application, after the electronic device determines that the pressure increases, it adds the pressure increase value to the pressure value corresponding to the target preset mass range to obtain 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 state of the coal gangue above one end of the partition plate close to the air ejection gun and other conditions, so that it is not easy for the coal gangue to enter the coal space below the partition plate when the air ejection gun separates coal gangue of the same mass subsequently, thereby improving the subsequent separation effect.

And substances with different densities have different absorption degrees of X-rays. Therefore, the first determination module 202 can determine the density of the coal gangue according to the X-ray image. The color image records a series of lengths of the coal gangue, etc. Therefore, the first determination module 202 can determine the contour of the coal gangue according to the color image.
