Description

Technical Field

[0001] This invention relates to the field of material storage, and more particularly to a method, apparatus, equipment, and medium for monitoring material stratification. Background Technology

[0002] To reduce material dust pollution, minimize land occupation, and lower costs, modern coking plants typically use silos as storage containers for materials. When storing materials, those with similar properties are usually placed in the same silo; however, different batches of material within the same silo can still exhibit certain differences in properties.

[0003] The discharge port at the bottom of the silo has a funnel-shaped structure. When material is discharged from the bottom of the silo, it may exhibit a non-uniform stratified discharge. During feeding, material falls into the silo from the discharge point, and the material is not uniformly layered either. Therefore, different batches of material may be non-uniformly layered within the silo. Currently, many level gauges have been developed on the market, such as radar level gauges, laser level gauges, ultrasonic level gauges, and plumb bob level gauges, but none of them can accurately determine the stratification of different batches of material within the silo. Therefore, how to monitor the stratification of material within the silo is a problem that urgently needs to be solved. Summary of the Invention

[0004] This application provides a material stratification monitoring method, apparatus, equipment, and medium, which solves the technical problem of difficulty in monitoring the stratification state of materials in silos in the prior art, and achieves the technical effect of being able to monitor the stratification state of materials in silos.

[0005] Firstly, this application provides a method for monitoring material stratification, the method comprising:

[0006] Before feeding, for multiple material points in the initial material surface in the silo, the initial material layering state is constructed according to the distance parameters corresponding to the material points in the first direction, the second direction and the third direction respectively. The first direction is perpendicular to the plane where the bottom of the silo is located, and the first direction, the second direction and the third direction are perpendicular to each other.

[0007] After feeding, for multiple material points in the first target material surface, the first target material layering state is constructed based on the distance parameters corresponding to the material points in the first direction, the second direction, and the third direction, respectively.

[0008] The first feed material stratification state is determined based on the difference between the initial material stratification state and the first target material stratification state.

[0009] Furthermore, the method includes:

[0010] After unloading, for multiple material points in the first target material surface, the layering state of the first target material is updated according to the change of the distance parameter corresponding to each material point in the first direction;

[0011] The initial material stratification state and the first feed material stratification state are updated based on the difference between the updated and unupdated first target material stratification states.

[0012] Furthermore, for multiple material points in the initial material level within the silo, an initial material stratification state is constructed based on the distance parameters corresponding to the material points in the first, second, and third directions, including:

[0013] Based on the distance parameter in the first direction of any material point among multiple material points on the initial material surface, a first target plane is determined, which is parallel to the plane where the bottom of the silo is located.

[0014] For multiple target regions within the first target plane, determine the range of distance parameters corresponding to the target regions in the second direction and the range of distance parameters corresponding to the third direction.

[0015] Based on the distance parameters corresponding to each material point in the initial material surface in the second direction and the distance parameters corresponding to each material point in the third direction, as well as the distance parameter range corresponding to each target area in the second direction and the distance parameter range corresponding to each target area in the third direction, the target area corresponding to each material point is determined.

[0016] For multiple target regions, the material points corresponding to the target regions are clustered to obtain the region points corresponding to the target regions;

[0017] By fitting and integrating the region points corresponding to multiple target regions, the initial material stratification state is obtained.

[0018] Furthermore, the method includes:

[0019] When the silo is simultaneously unloading and feeding, determine the maximum difference in the distance parameter between multiple material points in the second target material surface in the first direction;

[0020] If the maximum difference is less than the preset difference threshold, the silo will discharge material in a uniform layer.

[0021] If the maximum difference is greater than or equal to the preset difference threshold, the silo will discharge material in a non-uniform layered manner.

[0022] Furthermore, the method includes:

[0023] When the silo is discharging material in a non-uniform layered manner, determine the target collapse area in the second target material surface;

[0024] The feed point of the silo is changed to fill the target collapse area, so that the maximum difference is less than the preset difference threshold.

[0025] Furthermore, the method includes:

[0026] When the silo is discharging material in a uniform layered manner, the initial material layering state, the first target material layering state, and the first feed material layering state are updated based on the volume of the discharged material and the area of ​​the bottom surface of the silo.

[0027] Furthermore, the method includes:

[0028] For multiple material points in the second target material surface, the layering state of the second target material is determined based on the distance parameters of the material points in the first direction, the second direction, and the third direction.

[0029] The second feed material stratification state is determined based on the difference between the updated first target material stratification state and the second target material stratification state.

[0030] Secondly, this application provides a material stratification monitoring device, the device comprising:

[0031] The initial construction module is used to construct the initial material layering state for multiple material points in the initial material surface in the silo before feeding, based on the distance parameters corresponding to the material points in the first direction, the second direction and the third direction respectively. The first direction is perpendicular to the plane where the bottom of the silo is located, and the first direction, the second direction and the third direction are perpendicular to each other.

[0032] The first target construction module is used to construct the first target material layering state for multiple material points in the first target material surface after feeding, based on the distance parameters corresponding to the material points in the first direction, the second direction and the third direction respectively.

[0033] The first feed construction module is used to determine the first feed material stratification state based on the difference between the initial material stratification state and the first target material stratification state.

[0034] Thirdly, this application provides an electronic device, comprising:

[0035] processor;

[0036] Memory used to store processor-executable instructions;

[0037] The processor is configured to execute a material stratification monitoring method as provided in the first aspect.

[0038] Fourthly, this application provides a non-transitory computer-readable storage medium that, when the instructions in the storage medium are executed by the processor of an electronic device, enables the electronic device to perform a material stratification monitoring method as provided in the first aspect.

[0039] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0040] This application constructs an initial material stratification state for multiple material points on the initial material surface in the silo before feeding, based on distance parameters corresponding to the material points in a first direction, a second direction, and a third direction. After feeding, it constructs a first target material stratification state for multiple material points on a first target material surface, based on distance parameters corresponding to the material points in the first direction, a second direction, and a third direction. The first feeding material stratification state is determined based on the difference between the initial material stratification state and the first target material stratification state. By determining the first feeding material stratification state, the stratification state of the newly added material in the silo after feeding can be obtained. This application binds the obtained stratification state of the newly added material with the material information and uploads it to a client for display. Operators can determine subsequent production plans by viewing the information in the client.

[0041] This application also updates the initial material stratification state and the first feed material stratification state by changing the distance parameters corresponding to multiple material points in the first target material surface in the first direction after unloading. By updating the first feed material stratification state, the change in the first feed material stratification state after unloading from the silo can be determined. Operators can determine the subsequent production plan by viewing the changed first feed material stratification state in the client.

[0042] This application also determines the relationship between the maximum difference in distance parameters in the first direction between multiple material points on the second target material surface within the silo and a preset difference threshold when unloading and feeding are simultaneously occurring in the silo. If the maximum difference is greater than or equal to the preset difference threshold, the collapsed areas in the second target material surface are filled to ensure uniform layered unloading in the silo. When the silo unloads in a uniform layered manner, the material within the silo descends evenly, reducing the probability of mixing between different batches of material.

[0043] This application also involves simultaneous unloading and feeding in the silo. When the silo is uniformly layered for unloading, the initial material layering state, the first target material layering state, and the first feed material layering state are updated based on the volume of unloaded material and the area of ​​the silo's bottom surface. This allows for the acquisition of changes in the first feed material layering state. Furthermore, by considering the difference between the updated first target material layering state and the second target material layering state, the second feed material layering state is determined. By determining the second feed material layering state, the second feed material layering state of the feed portion can be obtained when unloading and feeding occur simultaneously in the silo. Operators can view the changed first and second feed material layering states on the client-side to determine subsequent production plans. Attached Figure Description

[0058] This application provides a material stratification monitoring method, which solves the technical problem in the prior art that it is difficult to monitor the stratification state of materials in silos.

[0059] The technical solution of this application embodiment is to solve the above-mentioned technical problems, and the general idea is as follows:

[0060] A material stratification monitoring method includes: before feeding, constructing an initial material stratification state for multiple material points on the initial material surface in the silo based on distance parameters corresponding to the material points in a first direction, a second direction, and a third direction, wherein the first direction is perpendicular to the plane where the bottom of the silo is located, and the first direction, the second direction, and the third direction are mutually perpendicular; after feeding, constructing a first target material stratification state for multiple material points on a first target material surface based on distance parameters corresponding to the material points in the first direction, the second direction, and the third direction; and determining a first feeding material stratification state based on the difference between the initial material stratification state and the first target material stratification state.

[0061] This application constructs an initial material stratification state for multiple material points on the initial material surface in the silo before feeding, based on distance parameters corresponding to the material points in a first direction, a second direction, and a third direction. After feeding, it constructs a first target material stratification state for multiple material points on a first target material surface, based on distance parameters corresponding to the material points in the first direction, a second direction, and a third direction. The first feeding material stratification state is determined based on the difference between the initial material stratification state and the first target material stratification state. By determining the first feeding material stratification state, the stratification state of the newly added material in the silo after feeding can be obtained. This application binds the obtained stratification state of the newly added material with the material information and uploads it to a client for display. Operators can determine subsequent production plans by viewing the information in the client.

[0062] This application also updates the initial material stratification state and the first feed material stratification state by changing the distance parameters corresponding to multiple material points in the first target material surface in the first direction after unloading. By updating the first feed material stratification state, the change in the first feed material stratification state after unloading from the silo can be determined. Operators can determine the subsequent production plan by viewing the changed first feed material stratification state in the client.

[0063] This application also determines the relationship between the maximum difference in distance parameters in the first direction between multiple material points on the second target material surface within the silo and a preset difference threshold when unloading and feeding are simultaneously occurring in the silo. If the maximum difference is greater than or equal to the preset difference threshold, the collapsed areas in the second target material surface are filled to ensure uniform layered unloading in the silo. When the silo unloads in a uniform layered manner, the material within the silo descends evenly, reducing the probability of mixing between different batches of material.

[0064] This application also involves simultaneous unloading and feeding in the silo. When the silo is uniformly layered for unloading, the initial material layering state, the first target material layering state, and the first feed material layering state are updated based on the volume of unloaded material and the area of ​​the silo's bottom surface. This allows for the acquisition of changes in the first feed material layering state. Furthermore, by considering the difference between the updated first target material layering state and the second target material layering state, the second feed material layering state is determined. By determining the second feed material layering state, the second feed material layering state of the feed portion can be obtained when unloading and feeding occur simultaneously in the silo. Operators can view the changed first and second feed material layering states on the client-side to determine subsequent production plans.

[0065] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0066] First, it should be clarified that the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0067] This application provides, as follows: Figure 1 The material stratification monitoring method shown includes steps S11-S13.

[0068] Step S11: Before feeding, for multiple material points in the initial material surface in the silo, construct the initial material layering state according to the distance parameters corresponding to the material points in the first direction, the second direction and the third direction respectively. The first direction is perpendicular to the plane where the bottom of the silo is located, and the first direction, the second direction and the third direction are perpendicular to each other.

[0069] Step S12: After feeding, for multiple material points in the first target material surface, construct the first target material layering state according to the distance parameters corresponding to the material points in the first direction, the second direction and the third direction respectively.

[0070] Step S13: Determine the first feed material stratification state based on the difference between the initial material stratification state and the first target material stratification state.

[0071] Regarding step S11, before feeding, for multiple material points in the initial material surface in the silo, an initial material layering state is constructed based on the distance parameters corresponding to the material points in the first direction, the second direction, and the third direction, respectively. The first direction is perpendicular to the plane where the bottom of the silo is located, and the first direction, the second direction, and the third direction are perpendicular to each other.

[0072] The material in silo 1 can be coal, and the uppermost surface of the material in silo 1 is called the material surface. Before feeding, the material stored in silo 1 that has not gone through steps S11-S13 is considered to be the same batch of material. The uppermost surface of the material stored in silo 1 is called the initial material surface, and there are multiple material points in the initial material surface.

[0073] The initial material layering state can be constructed based on the distance parameters corresponding to multiple material points in the initial material surface in the first direction, the second direction, and the third direction, respectively, specifically including steps S110-S114.

[0074] Step S110: Determine the first target plane based on the distance parameter in the first direction of any material point among multiple material points on the initial material surface. The first target plane is parallel to the plane where the bottom of the silo is located.

[0075] Step S111: For multiple target regions within the first target plane, determine the range of distance parameters corresponding to the target regions in the second direction and the range of distance parameters corresponding to the target regions in the third direction.

[0076] Step S112: Based on the distance parameters corresponding to each material point in the initial material surface in the second direction and the distance parameters corresponding to each material point in the third direction, as well as the distance parameter range corresponding to each target area in the second direction and the distance parameter range corresponding to each target area in the third direction, determine the target area corresponding to each material point.

[0077] Step S114: For multiple target areas, cluster the material points corresponding to the target areas to obtain the area points corresponding to the target areas.

[0078] Step S115: Fit and integrate the area points corresponding to multiple target areas to obtain the initial material stratification state.

[0079] Regarding step S110, a first target plane is determined based on the distance parameter in the first direction of any material point among multiple material points on the initial material surface. The first target plane is parallel to the plane where the bottom of the silo is located.

[0080] The first direction Z is perpendicular to the plane where the bottom of silo 1 is located, such as Figure 2 In this design, the plane containing the bottom of silo 1 is Z0, and the first direction Z is perpendicular to plane Z0. The second direction X, the third direction Y, and the first direction Z are all perpendicular to each other. The origins of the first direction Z, the second direction X, and the third direction Y can be set at any position. In this application, the origins are all set at the leftmost position of the bottom of the silo (silos are mostly cylindrical).

[0081] A material point can be arbitrarily selected from multiple material points on the initial material surface as the target material point. The first target plane is determined based on the distance parameter of the target material point in the first direction Z. The distance parameter of the first target plane in the first direction Z is the same as the distance parameter of the target material point in the first direction Z, and the first target plane is parallel to the plane where the bottom of the silo 1 is located.

[0082] like Figure 2 In the initial material surface K, the target material point is f. The distance parameters of the target material point f in the second direction X, the third direction Y, and the first direction Z are (x1, y1, z1). Based on the distance parameter z1 of the target material point f in the first direction Z, the distance parameter z1 of the target plane P in the first direction Z can be determined. Furthermore, the target plane P is parallel to the plane Z0. Thus, the target plane P can be determined.

[0083] Regarding step S111, for multiple target regions within the first target plane, determine the range of distance parameters corresponding to the target regions in the second direction and the range of distance parameters corresponding to the target regions in the third direction.

[0084] After obtaining the target plane, the target plane can be divided into multiple target regions. For each target region, the range of distance parameters corresponding to the target region in the second direction X and the range of distance parameters corresponding to the third direction Y are determined (the second direction X is parallel to the paper, and the third direction Y is perpendicular to the paper).

[0085] Figure 3 for Figure 2 A schematic diagram after dividing the target plane P (in the diagram) Figure 3This includes multiple material points corresponding to each target area. Figure 3 The target plane P has 13×13=169 target regions (each target region has the same length and width). The distance parameter range corresponding to each target region in the second direction X and the distance parameter range corresponding to the third direction Y are determined respectively (the blank target regions in the figure can be ignored in subsequent steps).

[0086] For example, Figure 3 The target region M has a distance parameter range of (9-10) in the second direction X and a distance parameter range of (4-5) in the third direction Y.

[0087] Regarding step S112, the target area corresponding to each material point is determined based on the distance parameters corresponding to each material point in the initial material surface in the second direction and the distance parameters corresponding to each material point in the third direction, as well as the distance parameter range corresponding to each target area in the second direction and the distance parameter range corresponding to each target area in the third direction.

[0088] For each material point in the initial material surface, the distance parameter of the material point in the second direction X is compared with the distance parameter range of each target area in the second direction X to determine the range of the material point in the second direction X. The distance parameter of the material point in the third direction Y is compared with the distance parameter range of each target area in the third direction Y to determine the range of the material point in the third direction Y. Based on the range of the material point in the second direction X and the range of the material point in the third direction Y, the corresponding target area of ​​the material point is determined.

[0089] like Figure 3 The distance parameters of material point N in the second direction X and the third direction Y are (9.5, 4.3), respectively. The distance parameter range of target area M in the second direction X and the distance parameter range of target area M in the third direction Y are (9-10, 4-5), respectively. The distance parameters of target area Q in the second direction X and the distance parameter range of target area Q in the third direction Y are (9-10, 5-6), respectively. The range of material point N in the second direction X is (9-10), and the range of material point N in the third direction Y is (4-5). Therefore, material point N is within target area M.

[0090] Regarding step S113, for multiple target areas, the material points corresponding to the target areas are clustered to obtain the area points corresponding to the target areas.

[0091] After determining the target region corresponding to each material point in the initial material surface, vertical clustering and planar clustering are performed on the material points corresponding to the target regions for multiple target regions (it should be noted that the material points corresponding to the target regions are not necessarily in the corresponding target regions, because the distance parameters between the target regions and the material points in the first direction Z may be different), to obtain one or more region points corresponding to the target regions. Figure 4 for Figure 3 The region points corresponding to the target regions are obtained by clustering the target regions in the target plane P.

[0092] Regarding step S114, the area points corresponding to multiple target areas are fitted and integrated to obtain the initial material stratification state.

[0093] After determining the corresponding region points for each target area, the region points are fitted to obtain the surface corresponding to the initial material surface. Based on the distance parameters of each region point in the surface along the first direction Z, the initial material stratification state of the material stored in silo 1 is determined. The material stratification state includes the volume and shape of the material in silo 1, as well as the corresponding distance parameters along the third direction Z.

[0094] Figure 5 for Figure 4 A schematic diagram of the initial material stratification state O of the material stored in silo 1, obtained by fitting and integrating the points in each region.

[0095] Step S12: After feeding, for multiple material points in the first target material surface, construct the first target material layering state according to the distance parameters corresponding to the material points in the first direction, the second direction and the third direction respectively.

[0096] "After feeding" refers to after feeding of silo 1 is completed. It should be noted that during the feeding process, the material level is constantly changing and unstable, so the first target material stratification state is also constantly changing. Therefore, by monitoring the material level after feeding is completed, a "stable" first target material stratification state can be constructed.

[0097] The method of “constructing the first target material layering state for multiple material points in the first target material surface according to the distance parameters corresponding to the material points in the first direction, the second direction and the third direction respectively” is similar to the method of “constructing the initial material layering state”. For details, please refer to steps S110-S114. Figure 6 This is a schematic diagram of the first target material layering state W inside silo 1 after feeding.

[0098] Step S13: Determine the first feed material stratification state based on the difference between the initial material stratification state and the first target material stratification state.

[0099] After obtaining the initial material stratification state of the material stored in silo 1 before feeding and the first target material stratification state of the material stored in silo 1 after feeding, the first feeding material stratification state of the material in the feeding section is determined based on the differences between the initial material stratification state and the first target material stratification state in terms of volume, shape, and distance parameters in the first direction Z.

[0100] like Figure 5 As shown, the initial material stratification state of the material already stored in silo 1 before feeding is O, as follows: Figure 6 As shown, the first target material stratification state of the material stored in silo 1 after feeding is W. Based on the differences in volume, shape, and distance in the first direction Z between the initial material stratification state O and the first target material stratification state W, the first feeding material stratification state of the material in the feeding section of silo 1 is determined as follows. Figure 7 E shown Figure 8 for Figure 7 A partially enlarged schematic diagram of the first feed material in stratified state E.

[0101] Furthermore, after determining the first material stratification status of the feed section, the material information of the feed section can be bound to the first material stratification status and uploaded to the client for display. The material information can include: material batch, feed time, and quality information. After viewing the first material stratification status and corresponding material information in the client, operators can plan the materials according to production needs. For example, if the first material stratification status is high-quality material, the corresponding material can be planned as a finishing material to produce higher value-added products.

[0102] After material is fed into silo 1, if the production requirements also include unloading, the material can be discharged from silo 1 according to the production requirements. After unloading, for multiple material points in the first target material surface, the layering state of the first target material can be updated according to the changes in the distance parameters corresponding to the material points in the first direction Z. Based on the updated layering state of the first target material and the differences between the first target material layers, the initial material layering state and the layering state of the first feed material can be updated.

[0103] Specifically, "after unloading" refers to the period after unloading from silo 1 is complete. It should be noted that during the unloading process, the material level is constantly changing and unstable (wormholes may exist), so the stratification state is also constantly changing. Therefore, by monitoring the material level after unloading, the changes in distance parameters corresponding to material points in the first direction can be obtained more accurately.

[0104] After unloading, because the material will be discharged from the discharge port 2 installed at the bottom of the silo 1, the distance parameter in the first direction Z corresponding to the material point in the first target material surface will change. For multiple material points in the first target material surface, the layering state of the first target material is updated according to the distance parameter in the second direction X, the distance parameter in the third direction Y, and the changed distance parameter in the first direction Z, to obtain the updated layering state of the first target material. The method of "updating the layering state of the first target material according to the distance parameter in the second direction X, the distance parameter in the third direction Y, and the changed distance parameter in the first direction Z" can also refer to steps S110-S114.

[0105] After updating the stratification state of the first target material, based on the differences in volume, shape, and distance parameters in the first direction Z between the updated and unupdated first target material stratification states, material deduction is performed on both the initial material stratification state and the first feed material stratification state to obtain the updated initial material stratification state and the updated first feed material stratification state. Specifically, the deducted volume equals the unloading volume, and the changes in the initial material surface and the first target material surface are determined based on the shape differences between the first target material stratification state and the unupdated first target material.

[0106] Figure 9 This is a schematic diagram of the material distribution within a certain silo 1. Figure 9 In the diagram, b represents the material in silo 1 before unloading, and c represents the material in silo 1 after unloading. The difference between c and b is a. Based on the difference a, the initial material stratification state is determined (not yet in...). Figure 9 (as shown in the image) and the stratification state of the first feed material (not shown in the image). Figure 9 (As shown in the figure) Material deduction is performed to achieve the purpose of updating the initial material stratification state and the stratification state of the first feed material.

[0107] When production demands include both unloading and feeding, silo 1 simultaneously feeds and unloads. During this process, the maximum difference in distance parameters between multiple material points on the second target material surface in the first direction is determined. If the maximum difference is less than a preset difference threshold, silo 1 performs uniform layered unloading. If the maximum difference is greater than or equal to the preset difference threshold, silo 1 performs non-uniform layered unloading.

[0108] The second target material level is the material level of the newly added material on the uppermost surface of silo 1 at any given moment when silo 1 is in a state of simultaneous feeding and unloading. The second target material level includes multiple material points. For the multiple material points in the second target material level, the minimum value and the maximum value of the distance parameter in the first direction of the multiple material points are determined. The maximum difference is determined based on the minimum value and the maximum value of the distance parameter in the first direction.

[0109] If the maximum difference is less than the preset difference threshold, it indicates that the height difference between the highest and lowest points of the material surface within the second material surface is small, there are no "wormholes" within silo 1, and the material in silo 1 is discharged in a uniform layer when discharged from discharge port 2. If the maximum difference is greater than or equal to the preset difference threshold, it indicates that the height difference between the highest and lowest points of the material surface within the second material surface is too large, there are "wormholes" within silo 1, and the material in silo 1 is discharged in a non-uniform layer when discharged from discharge port 2. The preset difference threshold can be selected based on the volume, height, and bottom area of ​​the silo.

[0110] Furthermore, when silo 1 is discharging material in a non-uniform layered manner, the feed point of the silo is changed so that the maximum difference within the target collapse area is less than the preset difference threshold.

[0111] When silo 1 discharges material in a non-uniform layered manner, it indicates that the height difference between the highest and lowest points of the second target material surface in silo 1 is too large, and there is a target collapse area within the second target material surface. By changing the position of the feeding trolley 3, the discharge point of the feeding trolley 3 is changed, thereby achieving the purpose of filling the target collapse area with material. By filling the target collapse area with material, the maximum difference is made less than or equal to a preset difference threshold. When the maximum difference of the distance parameter between multiple material points in the first direction in the second target material surface is less than or equal to the preset difference threshold, the silo can be considered as discharging material in a uniform layered manner.

[0112] Furthermore, when silo 1 is discharging material in a uniform layered manner, the initial material layering state, the first target material layering state, and the first feed material layering state are updated based on the volume of the discharged material and the area of ​​the bottom surface of the silo.

[0113] When silo 1 discharges material in a uniform layer, it means that the material inside silo 1 is discharged in a uniform layer from discharge port 2. Based on the volume of the discharged material and the area of ​​the silo's bottom surface, the corresponding height of the discharged material within the silo can be determined. For example, if the volume of the discharged material is 100 m³... 3 If the bottom area of ​​the silo is 10 square meters, then the height of the unloaded material inside the silo is 100 meters. 3 ÷10m 2=10m. And since the silo discharges material in a uniform layered manner, the material is directly deducted from the initial material layering state, the first target material layering state, and the first feed material layering state based on the height of the discharged material in the silo. This yields the updated initial material layering state, the updated first target material layering state, and the updated first feed material layering state.

[0114] Furthermore, when production needs include both unloading and feeding, the silo 1 also contains additional material. For multiple material points in the second target material surface, the second target material layering state can be determined based on the distance parameters corresponding to the material points in the first direction Z, the second direction X, and the third direction Y. The second feeding material layering state can be determined based on the difference between the updated first target material layering state and the second target material layering state.

[0115] The method of "determining the second target material stratification state based on the distance parameters of the material points in the first, second, and third directions for multiple material points in the second target material surface" can refer to steps S110-S114. The method of "determining the second feed material stratification state based on the difference between the updated first target material stratification state and the second target material stratification state" is similar to the method of "determining the first feed material stratification state based on the difference between the initial material stratification state and the first target material stratification state," and can be found in step S13. Determining the second target material stratification state means that the second target material stratification state of the newly added material can be obtained when the silo is simultaneously feeding and discharging.

[0116] In summary, this application constructs an initial material stratification state for multiple material points on the initial material surface in the silo before feeding, based on distance parameters corresponding to the material points in the first, second, and third directions. After feeding, it constructs a first target material stratification state for multiple material points on the first target material surface, based on distance parameters corresponding to the material points in the first, second, and third directions. The first feeding material stratification state is determined based on the difference between the initial and first target material stratification states. By determining the first feeding material stratification state, the stratification state of the newly added material in the silo after feeding can be obtained. This application binds the obtained stratification state of the newly added material with material information and uploads it to a client for display. Operators can determine subsequent production plans by viewing the information in the client.

[0117] This application also updates the initial material stratification state and the first feed material stratification state by changing the distance parameters corresponding to multiple material points in the first target material surface in the first direction after unloading. By updating the first feed material stratification state, the change in the first feed material stratification state after unloading from the silo can be determined. Operators can determine the subsequent production plan by viewing the changed first feed material stratification state in the client.

[0118] This application also determines the relationship between the maximum difference in distance parameters in the first direction between multiple material points on the second target material surface within the silo and a preset difference threshold when unloading and feeding are simultaneously occurring in the silo. If the maximum difference is greater than or equal to the preset difference threshold, the collapsed areas in the second target material surface are filled to ensure uniform layered unloading in the silo. When the silo unloads in a uniform layered manner, the material within the silo descends evenly, reducing the probability of mixing between different batches of material.

[0119] This application also involves simultaneous unloading and feeding in the silo. When the silo is uniformly layered for unloading, the initial material layering state, the first target material layering state, and the first feed material layering state are updated based on the volume of unloaded material and the area of ​​the silo's bottom surface. This allows for the acquisition of changes in the first feed material layering state. Furthermore, by considering the difference between the updated first target material layering state and the second target material layering state, the second feed material layering state is determined. By determining the second feed material layering state, the second feed material layering state of the feed portion can be obtained when unloading and feeding occur simultaneously in the silo. Operators can view the changed first and second feed material layering states on the client-side to determine subsequent production plans.
