Description

Technical Field

[0001] The embodiments of the present invention relate to the field of industrial measurement technology, and in particular to a material layering management system based on a three-dimensional measurement device. Background Art

[0002] In all industries, production materials are the core elements of value creation. Scientific storage, protection and management of these materials can effectively ensure product quality while maximizing industry profits.

[0003] However, in actual production, some materials often have a shelf life due to their physical and chemical properties. For example, in some industrial scenarios, the shelf life of carbon powder is around 15 days. This can make it difficult for existing material management equipment or methods to monitor the usage of any single batch of materials, resulting in low management efficiency and large monitoring errors. If multiple batches of materials are already stored in a container (such as a storage tank) before a batch of materials is stored, or if multiple batches of materials need to be added after a batch of materials is stored, and the subsequent loading and unloading processes may also occur during these multiple loading and unloading processes, then monitoring the usage of any single batch of materials is difficult. Summary of the Invention

[0027] The single-point measurement modules are all installed inside the device body;

[0028] The single-point measurement module has a wave emitting point in a single direction and correspondingly forms an outgoing beam in a single direction.

[0029] In a second aspect, an embodiment of the present invention further provides a material layer management system based on a three-dimensional measuring device, comprising a management device and the three-dimensional measuring device;

[0030] The three-dimensional measuring device is mounted on a container; after the container performs at least one feeding process within a first preset time period, the container performs at least one discharging process within a second preset time period; the three-dimensional measuring device is used to obtain the internal shape of the container before the first feeding of the container; and, within the first preset time period, obtain the feeding shape data of the material after each feeding of the container; and, within the second preset time period, obtain the real-time shape data of the material during each discharging process of the container;

[0031] The management device establishes a communication connection with the three-dimensional measuring device, and is at least used to obtain and establish an initial material stratification model of the container based on the internal shape of the container and the feeding shape data of the material after each feeding of the container within the first preset time period; and determine the real-time discharge form of the initial material stratification model based on the container characteristic parameters and the material characteristic parameters of each layer of material in the initial material stratification model; and, in any discharge process of the container, adjust the distribution of each layer of material in the initial material stratification model based on the real-time discharge form to obtain a real-time material stratification model, and parse the real-time discharge information of the container based on the real-time shape data, and then perform management operations on the container discharge process in combination with the real-time material stratification model and the real-time discharge information of the container.

[0032] The technical solution provided by the embodiments of the present invention uses a three-dimensional measurement device to obtain the internal shape of a container before the first material loading and obtains the material shape data after each material loading before the first material discharge. A management device then obtains and establishes an initial material stratification model for the container before the first material discharge based on the internal shape of the container and all material shape data before the first material discharge. Furthermore, the management device determines the real-time discharge pattern of the initial material stratification model before the first material discharge based on the container characteristic parameters and the material characteristic parameters of each layer in the initial material stratification model before the first material discharge. During the first material discharge process, the three-dimensional measurement device obtains real-time material shape data, and the management device analyzes the real-time material shape data to obtain real-time container discharge information. Simultaneously, the management device adjusts the distribution of each layer in the initial material stratification model before the first material discharge based on the real-time discharge pattern of the initial material stratification model before the first material discharge, thereby obtaining a real-time material stratification model for the first material discharge. Finally, the management device combines the real-time material stratification model and the real-time container discharge information to manage the container discharge process.

[0033] (When M is 2) The three-dimensional measuring device acquires material form data after each loading of the container, within the time span between the first discharge and the second discharge. The management device then establishes an initial material stratification model before the second discharge based on the material stratification model after the first discharge and all material form data from the time span between the first discharge and the second discharge. Furthermore, the management device determines the real-time discharge form of the initial material stratification model before the second discharge based on the container's characteristic parameters and the material characteristic parameters of each layer in the initial material stratification model before the second discharge. During the second discharging process of the container, the three-dimensional measuring device obtains the real-time morphological data of the material, and the management device parses the real-time discharging information of the container based on the real-time morphological data; at the same time, the management device adjusts the distribution of each layer of material in the initial material stratification model before the second discharging of the container based on the real-time discharging form of the initial material stratification model before the second discharging of the container, and obtains the real-time material stratification model of the second discharging of the container; finally, the management device manages the container discharging process in combination with the real-time material stratification model and the real-time discharging information of the container.

[0034] Similarly, (when M equals 3) the 3D measurement device acquires material form data after each loading of the container, during the time span between the second and third discharges. The management device then establishes an initial material stratification model before the third discharge based on the material stratification model after the second discharge and all material form data from the second and third discharges. Furthermore, the management device determines the real-time discharge form of the initial material stratification model before the third discharge based on the container's characteristic parameters and the material characteristic parameters of each layer in the initial material stratification model before the third discharge. During the third discharge of the container, the 3D measurement device acquires real-time material shape data, and the management device analyzes the real-time container discharge information based on the real-time shape data. Simultaneously, the management device adjusts the distribution of materials in each layer of the initial material stratification model based on the real-time discharge form of the initial material stratification model before the third discharge, thereby obtaining a real-time material stratification model for the third discharge of the container. Finally, the management device combines the real-time material stratification model and the real-time container discharge information to manage the container discharge process. This process continues in this manner and is not further elaborated.

[0035] Thus, the material stratification management system in the embodiments of the present invention, by establishing a material stratification model, can monitor the usage of multiple batches of materials stored in a container. Furthermore, because solid materials have low compressibility, the morphology of each layer (i.e., each batch) of material in the initial material stratification model before unloading from the container is relatively stable. However, during unloading from the container, the real-time unloading of multiple layers of material is complex, resulting in low management efficiency and large monitoring errors in existing material management devices or methods. In view of this, during the container discharging process, the embodiment of the present invention can, on the one hand, adjust the distribution of materials in each layer in the initial material stratification model before each container discharging based on the real-time discharging form of the initial material stratification model before each container discharging through the management device, and obtain the real-time material stratification model for each container discharging; on the other hand, the embodiment of the present invention can use a three-dimensional measuring device to obtain the real-time morphological data of the material in the container discharging process (such as three-dimensional point cloud data of the material surface, material height data, etc.), and then parse the real-time discharging information of the container (such as discharging volume, discharging quality, etc.) based on the real-time morphological data; finally, the container discharging process is managed in combination with the real-time material stratification model and the real-time discharging information of the container (for example, after the 1 ton of material in the bottom layer of the container is discharged, the container discharge port is closed in time, etc.), which is conducive to reducing the monitoring error of the material stratification management system and improving the management efficiency of the material stratification management system.

It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0045] Figure 1 This is a structural diagram of a material layer management system based on a three-dimensional measurement device provided by an embodiment of the present invention. Figure 1 As shown, the material layer management system based on the three-dimensional measuring device 110 includes a management device 120 and the three-dimensional measuring device 110 .

[0046] The three-dimensional measuring device 110 is installed on the container and is used to obtain the internal shape of the container at least before the first material is fed into the container; and to obtain the material shape data after each material feeding into the container within the time span before the first material is discharged from the container and from the (M-1)th material discharge to the Mth material discharge.

[0047] The management device 120 establishes a communication connection with the three-dimensional measuring device 110, and is at least used to obtain and establish an initial material stratification model of the container before the first discharge based on the internal shape of the container and all material shape data of the container before the first discharge; and, based on the material stratification model after the (M-1)th discharge of the container and all material shape data in the time span from the (M-1)th discharge of the container to the Mth discharge of the container, establish the initial material stratification model of the container before the Mth discharge; and, based on the container characteristic parameters and the material characteristic parameters of each layer of material in the initial material stratification model, determine the real-time discharge form of the initial material stratification model; and, during any discharge process of the container, adjust the distribution of each layer of material in the initial material stratification model based on the real-time discharge form to obtain a real-time material stratification model, and parse the real-time discharge information of the container based on the real-time shape data, and then manage the container discharge process in combination with the real-time material stratification model and the real-time discharge information of the container.

[0048] Wherein, M≥2, and M is a positive integer.

[0049] It can be seen that the state of the material is preferably set to solid; the container can be a silo, a storage tank, etc.; the three-dimensional measurement device 110 can be, but is not limited to, a 3D radar.

[0050] Depending on the application scenario, the container can be used to store only one material (such as carbon powder in the chemical industry), or it can be used to store multiple materials (such as various types of grains in the food industry).

[0051] It is understandable that if the container is large and only one three-dimensional measuring device 110 is installed on the container, the single three-dimensional measuring device 110 may be affected by obstacles such as ladders, pipes, and support structures in the container blocking the signal, resulting in low measurement accuracy, or it may be limited by the repose angle caused by the filling level of the material in the container, and only local material morphological data can be obtained.

[0052] Based on this, in order to reduce the impact of the above situation on the material stratification management system, the number of three-dimensional measuring devices 110 in the material stratification management system can be multiple (that is, in some embodiments, optionally, the number of three-dimensional measuring devices 110 is at least one), and before the material stratification management system works, the parameters of each three-dimensional measuring device 110 can be calibrated in advance to improve the accuracy of the internal shape of the container, material shape data, real-time shape data, etc.

[0053] The real-time discharge form includes at least one of funnel flow, bulk flow, or mixed flow (including both funnel flow and bulk flow discharge forms). The material layering model can be established by the management device 120 based on any existing simulation software, such as EDEM software, but is not limited to it.

[0054] For example, the working principle of the material layering management system can be specifically as follows:

[0055] The three-dimensional measuring device 110 obtains the container's internal shape before the first material loading and obtains the material shape data after each loading before the first material discharge. The management device 120 then obtains and establishes an initial material stratification model for the container before the first material discharge based on the container's internal shape and all material shape data before the first material discharge. Furthermore, the management device 120 determines the real-time discharge form of the initial material stratification model before the first material discharge based on the container's characteristic parameters and the material characteristic parameters of each layer in the initial material stratification model before the first material discharge. During the first discharging process of the container, the three-dimensional measuring device 110 obtains the real-time morphological data of the material (for example, the three-dimensional point cloud data of the material surface, the material height data, etc.), and the management device 120 parses the real-time discharging information of the container (for example, the discharging volume, the discharging mass, etc.) based on the real-time morphological data of the material; at the same time, the management device 120 adjusts the distribution of the materials in each layer in the initial material stratification model before the first discharging of the container based on the real-time discharging form of the initial material stratification model before the first discharging of the container, and obtains the real-time material stratification model of the first discharging of the container; finally, the management device 120 manages the container discharging process in combination with the real-time material stratification model and the real-time discharging information of the container (for example, after the 1 ton of material at the bottom layer of the container is discharged, the container's discharge valve, belt weighing and conveying system are closed in time).

[0056] (When M is 2) The three-dimensional measuring device 110 acquires material form data after each loading of the container, within the time span between the first discharge and the second discharge. The management device 120 then establishes an initial material stratification model before the second discharge based on the material stratification model after the first discharge and all material form data from the time span between the first discharge and the second discharge. Furthermore, the management device 120 determines the real-time discharge form of the initial material stratification model before the second discharge based on the container's characteristic parameters and the material characteristic parameters of each layer in the initial material stratification model before the second discharge. During the second discharging process of the container, the three-dimensional measuring device 110 obtains the real-time morphological data of the material, and the management device 120 parses the real-time discharging information of the container based on the real-time morphological data; at the same time, the management device 120 adjusts the distribution of each layer of material in the initial material stratification model before the second discharging of the container based on the real-time discharging form of the initial material stratification model before the second discharging of the container, and obtains the real-time material stratification model of the second discharging of the container; finally, the management device 120 manages the container discharging process in combination with the real-time material stratification model and the real-time discharging information of the container.

[0057] (When M is 3) The three-dimensional measuring device 110 acquires material form data after each loading of the container, during the time span between the second and third discharges. The management device 120 then establishes an initial material stratification model before the third discharge based on the material stratification model after the second discharge and all material form data from the second and third discharges. Furthermore, the management device 120 determines the real-time discharge form of the initial material stratification model before the third discharge based on the container's characteristic parameters and the material characteristic parameters of each layer in the initial material stratification model before the third discharge. During the third unloading process, the 3D measuring device 110 acquires real-time material shape data. The management device 120 analyzes this real-time shape data to generate real-time unloading information. Simultaneously, the management device 120 adjusts the distribution of materials within each layer of the initial material stratification model based on the real-time unloading pattern of the initial material stratification model before the third unloading process, generating a real-time material stratification model for the third unloading process. Finally, the management device 120 combines the real-time material stratification model and the real-time unloading information to manage the unloading process. (When M is 4), the 3D measuring device 110 acquires material shape data after each loading of the container from the third unloading process to the fourth unloading process. Then, based on the material stratification model after the third unloading process and all material shape data from the third unloading process to the fourth unloading process, the management device 120 establishes the initial material stratification model for the fourth unloading process. Furthermore, the management device 120 determines the real-time discharge form of the initial material stratification model of the container before the fourth discharge based on the container characteristic parameters and the material characteristic parameters of each layer in the initial material stratification model before the fourth discharge of the container. During the fourth discharge of the container, the three-dimensional measurement device 110 obtains the real-time morphological data of the material, and the management device 120 parses the real-time discharge information of the container based on the real-time morphological data. At the same time, the management device 120 adjusts the distribution of each layer of material in the initial material stratification model before the fourth discharge of the container based on the real-time discharge form of the initial material stratification model before the fourth discharge of the container, thereby obtaining a real-time material stratification model for the fourth discharge of the container. Finally, the management device 120 combines the real-time material stratification model and the real-time discharge information of the container to manage the container discharge process. And so on, no further details will be given.

[0058] In summary, the material stratification management system in the embodiments of the present invention can monitor the usage of multiple batches of materials stored in a container by establishing a material stratification model. Because solid materials have low compressibility, the morphology of each layer of material in the initial material stratification model before the container is discharged is relatively stable. However, during the container discharge process, the real-time discharge of the multi-layered material is relatively complex, resulting in low management efficiency and large monitoring errors in existing material management devices or methods. In view of this, during the container discharge process, the embodiments of the present invention can, on the one hand, use a management device to adjust the distribution of each layer of material in the initial material stratification model before each discharge of the container based on the real-time discharge form of the initial material stratification model before each discharge of the container, thereby obtaining a real-time material stratification model for each discharge of the container. Furthermore, the embodiments of the present invention can utilize a three-dimensional measurement device to obtain real-time morphological data of the material during the container discharge process, and then parse the real-time container discharge information based on the real-time morphological data. Finally, the container discharge process is managed by combining the real-time material stratification model and the real-time container discharge information, thereby reducing monitoring errors and improving the management efficiency of the material stratification management system.

[0059] It should be noted that, depending on the type of signal being transmitted and received, a three-dimensional measurement device can be a 3D microwave radar, a 3D lidar, or other similar device. It is understood that when materials are being loaded or unloaded from a container, especially when powdered solid materials are being poured into the container, the material level and the three-dimensional shape of the material surface will fluctuate constantly, generating a large amount of dust and smoke. Under such harsh measurement conditions, the laser signals transmitted and received by a 3D lidar are easily obscured by dust and smoke, making reliable measurement difficult. However, a 3D microwave radar, which operates based on the microwave measurement principle, is virtually unaffected by dust and smoke. Therefore, to ensure that the three-dimensional measurement device can achieve excellent detection and measurement accuracy even during container loading and unloading, a 3D microwave radar is a preferred option.

[0060] Furthermore, based on various measurement principles, the 3D measurement device can be, for example, a 3D scanning radar or a 3D multi-point radar. In one embodiment of the present invention, the 3D measurement device can be a phased array 3D scanning radar. Optionally, the 3D measurement device includes at least one antenna array capable of digital beamforming. The antenna array can include multiple transmitting and / or receiving elements, which can be implemented within a single antenna or distributed across multiple independent antennas.

[0061] In another embodiment provided by the present invention, the 3D measurement device may be a purely mechanical 3D scanning radar. Optionally, the 3D measurement device includes at least a mechanical motion structure and a scanning probe. The mechanical motion structure drives the scanning probe to rotate, at least enabling the scanning probe to have multiple directional wave emission points and correspondingly form multiple directional outgoing beams. The mechanical motion structure may have multiple directional motion dimensions (e.g., horizontal, pitch, and vertical), the scanning probe may be a microwave sensor, a laser sensor, etc., and the outgoing beam may be a microwave signal, a laser signal, etc.

[0062] In another embodiment provided by the present invention, the three-dimensional measurement device may be a composite 3D scanning radar (combining a phased array and a mechanical system); optionally, the three-dimensional measurement device includes at least a mechanical motion structure and a scanning probe, wherein the mechanical motion structure drives the scanning probe to rotate, so that at least the scanning probe has wave emission points in multiple directions and correspondingly forms outgoing beams in multiple directions, and the scanning probe is an antenna array that can be used for digital beamforming.

[0063] In another implementation provided by an embodiment of the present invention, the three-dimensional measuring device can, for example, be composed of multiple radars based on the single-point measurement principle; optionally, the three-dimensional measuring device is composed of at least multiple independent single-point measurement sub-devices (such as single-point laser radars, single-point microwave radars, etc.), and different single-point measurement sub-devices are installed at different positions of the container. The single-point measurement sub-device has a wave emitting point in a single direction and forms an output beam in a single direction accordingly.

[0064] In another embodiment provided by an embodiment of the present invention, the three-dimensional measurement device can be a 3D multi-point radar; optionally, the three-dimensional measurement device includes at least a device body (for example, it can be composed of a shell and a cover) and multiple single-point measurement modules (for example, they can be laser sensors, microwave sensors, etc.); the single-point measurement modules are all installed inside the device body; the single-point measurement modules have a wave emitting point in a single direction and correspondingly form an outgoing beam in a single direction.

[0065] It should also be noted that in the actual discharging process of materials in the container, the discharging process of different containers is different because each layer of material is affected by its own gravity, friction between materials, friction between materials and containers, and factors such as the container geometry, the shape and size of the particles in each layer of material.

[0066] For example, Figure 2 This is a schematic diagram of a container discharging state provided by an embodiment of the present invention. Figure 3 This is another schematic diagram of a container discharging state provided by an embodiment of the present invention. Figure 4 This is another schematic diagram of a container discharging state provided by an embodiment of the present invention. Figure 2For a container with a single discharge port, the discharge process can generally be divided into two stages. In the initial discharge stage, the material at the bottom of the container is discharged in a "funnel" shape, while the overall material surface shape of the material near the top of the container remains basically unchanged and decreases as a whole. In the later stage of discharge, as the influence range of the "funnel" continues to expand, a funnel-shaped "discharge channel" will appear in the axial direction of the container discharge port. The layers of material on both sides of the "discharge channel" are almost stationary, and the material near the top of the container flows out of the container through the "discharge channel". Figure 3 and Figure 4 As shown, unlike single-discharge port containers, multi-discharge port containers ( Figure 3 and Figure 4 The example shows that the container has two discharge ports. The discharge situation is related to the opening and closing status of the discharge port. Figure 3 When the opening and closing states of the discharge ports are consistent, the container can basically achieve balanced discharge, that is, the stratification of the materials in each layer of the container remains almost unchanged and the overall level decreases. Figure 4 When the opening and closing states of the discharge ports are inconsistent, the material near the discharge port with the larger opening will descend faster.

[0067] Thus, in some embodiments, the container characteristic parameters optionally include at least one of the following: container structural parameters, container material parameters, and the degree of opening and closing of the discharge port during the container discharge process; the material characteristic parameters of each layer of material include at least one of the following: particle morphology of each layer of material, friction coefficient between each layer of material and the container, friction coefficient between each layer of material, particle density of each layer of material, shear modulus of particles of each layer of material, coefficient of restitution of particles of each layer of material, humidity of each layer of material, and surface adhesion parameters of each layer of material. The container structural parameters may, for example, be the cone angle parameters of a container having a conical structure, discharge port size parameters, and container body size parameters; and the degree of opening and closing of the discharge port during the container discharge process may, for example, be fully open, half-open, or closed.

[0068] Based on the above embodiments, Figure 5 This is a structural diagram of another material layer management system based on a three-dimensional measurement device provided by an embodiment of the present invention. Figure 5 As shown, optionally, the three-dimensional measuring device 110 is also used to at least determine the time of obtaining the material form data after each feeding of the container and upload it to the management device 120; the management device 120 is also used to at least correspond the time of obtaining the material form data after each feeding of the container to each layer of material in the material layering model to generate time management information of the material layering model.

[0069] Optionally, an alarm device 130 is also included; when the time management information of at least one layer of material in the material layering model is in an abnormal state, the management device 120 generates an alarm instruction (for example, it can be a wired signal or a wireless signal); the alarm device 130 is connected to the management device 120, and is at least used to obtain and send an alarm signal to the user according to the alarm instruction.

[0070] Optionally, it also includes: a front-end analysis device 140, which is connected to the management device 120, and is at least used to obtain the material characteristic parameters of each layer of materials in the initial material stratification model and upload them to the management device 120; the management device 120 is at least also used to correspond the material characteristic parameters of each layer of materials to the material stratification model to generate other management information of the material stratification model.

[0071] Among them, material shape data may include material three-dimensional shape diagram, highest material level, lowest material level, average material level, material volume, material mass, etc.

[0072] For example, the management device 120 can determine the expiration time of each layer of material based on the corresponding feeding time of each layer of material in the material stratification model (for example, the expiration time of carbon powder is the feeding time plus 15 days). When a layer or layers of material are about to expire (for example, the day before the expiration time), the management device 120 controls the alarm device 130 (such as a buzzer, warning light, warning slogan, etc.) to warn the user; or, the management device 120 summarizes the material morphology data after each feeding of the container, and parses the layer thickness distribution information of the multi-layer material, that is, the thickness information of a layer of material in a certain vertical direction.

[0073] The pre-analysis device 140 may include a testing platform, a belt scale, a density meter, a hygrometer, and the like. For example, the hygrometer can be used to determine the humidity of each material layer; the testing platform can be used to determine the particle morphology of each material layer, the friction coefficient between each material layer and the container, the friction coefficient between each material layer, the particle density of each material layer, the shear modulus of each material layer, the coefficient of restitution of each material layer, and the surface adhesion parameters of each material layer. The management device 120 can generate material type management information based on the material stratification model and the types of materials in each layer; or it can generate material component content management information based on the material stratification model and the component content of each material layer.

[0074] It can be seen that the material stratification management system in the embodiment of the present invention can, on the one hand, monitor the usage of multiple batches of materials stored in containers by establishing a material stratification model; on the other hand, it can also be used with front-end analysis devices such as testing platforms, belt scales, density meters, and hygrometers to adaptively obtain the type, component content, composition, origin, quality, density, humidity and other parameters of each layer of material, and assign the above parameters to each layer in the material stratification model, thereby improving the human-computer interaction performance and monitoring accuracy of the material stratification management system.

[0075] At the same time, because solid materials have low compressibility, the shapes of materials in each layer (i.e., each batch) in the initial material stratification model before container discharge are relatively stable. However, during the container discharge process, the real-time discharge of multi-layer materials is relatively complicated, and the management efficiency of existing material management equipment or methods is low, and the monitoring error is large. In view of this, during the container discharge process, the embodiment of the present invention can, on the one hand, adjust the distribution of materials in each layer in the initial material stratification model before each container discharge based on the real-time discharge form of the initial material stratification model before each container discharge, and obtain a real-time material stratification model for each container discharge. On the other hand, the embodiment of the present invention can use a three-dimensional measuring device to obtain real-time morphological data of the material in the container discharge process, and then parse the real-time container discharge information based on the real-time morphological data. Finally, the container discharge process is managed and operated in combination with the real-time material stratification model and the real-time container discharge information, which is conducive to reducing the monitoring error of the material stratification management system and improving the management efficiency of the material stratification management system.

[0076] In actual production, if materials (such as grain) have a long shelf life and do not require frequent discharge, the following technical solutions can be used to monitor the usage of multiple batches of materials stored in containers. This helps reduce monitoring errors in the material stratification management system and improve its management efficiency.

[0077] Based on the above embodiments or implementation methods, continue to refer to Figure 1 The material layering management system based on the three-dimensional measuring device includes a management device 120 and a three-dimensional measuring device 110 .

[0078] The three-dimensional measuring device 110 is installed on the container; after the container performs at least one feeding process within a first preset time period, it performs at least one discharging process within a second preset time period (the first preset time period and the second preset time period can be changed according to actual adaptability on site); the three-dimensional measuring device 110 is at least used to obtain the internal shape of the container before the container is fed for the first time; and, within the first preset time period, obtain the feeding shape data of the material after each feeding of the container; and, within the second preset time period, obtain the real-time shape data of the material in each discharging process of the container.

[0079] The management device 120 establishes a communication connection with the three-dimensional measuring device 110, and is at least used to obtain and establish an initial material stratification model of the container based on the internal shape of the container and the feeding shape data of the material after each feeding of the container within a first preset time period; and, based on the characteristic parameters of the container and the material characteristic parameters of each layer of material in the initial material stratification model, determine the real-time discharge form of the initial material stratification model; and, in the first discharge process of the container, adjust the distribution of each layer of material in the initial material stratification model based on the real-time discharge form of the initial material stratification model to obtain a real-time material stratification model, and parse the real-time discharge information of the container based on the real-time shape data, and then combine the real-time material stratification model and The real-time discharging information of the container is used to perform management operations on the container discharging process; and, in the M-th discharging process of the container, the material stratification model after the (M-1)-th discharging of the container is used as the initial material stratification model before the M-th discharging of the container, and the real-time discharging form of the initial material stratification model is determined according to the characteristic parameters of the container and the material characteristic parameters of each layer of material in the initial material stratification model. Based on the real-time discharging form of the initial material stratification model, the distribution of each layer of material in the initial material stratification model is adjusted to obtain the real-time material stratification model, and the real-time discharging information of the container is parsed according to the real-time morphological data, and then the management operations on the container discharging process are performed in combination with the real-time material stratification model and the real-time discharging information of the container.

[0080] Specifically, the three-dimensional measuring device 110 obtains the internal shape of the container before the first material is fed into the container, and obtains the material feeding shape data after each material feeding into the container within a first preset time period. Thereafter, the management device 120 obtains and establishes an initial material stratification model for the container based on the internal shape of the container and the material feeding shape data after each material feeding into the container within the first preset time period. Furthermore, the management device 120 determines the real-time discharge form of the initial material stratification model based on the characteristic parameters of the container and the material characteristic parameters of each layer of material in the initial material stratification model. During the first discharge process of the container, the management device 120 adjusts the distribution of each layer of material in the initial material stratification model based on the real-time discharge form of the initial material stratification model to obtain a real-time material stratification model, and parses the real-time discharge information of the container based on the real-time shape data. Furthermore, the management device 120 performs management operations on the container discharge process in combination with the real-time material stratification model and the real-time discharge information of the container.

[0081] (When M is equal to 2) the three-dimensional measuring device 110 obtains real-time morphological data of the material during the second unloading process of the container. Then, during the second unloading process of the container, the management device 120 uses the material stratification model after the first unloading process of the container as the initial material stratification model before the second unloading process of the container. Based on the container characteristic parameters and the material characteristic parameters of each layer of material in the initial material stratification model before the second unloading process of the container, the management device 120 determines the real-time unloading form of the initial material stratification model before the second unloading process of the container. Based on the real-time unloading form of the initial material stratification model before the second unloading process of the container, the management device 120 adjusts the distribution of each layer of material in the initial material stratification model before the second unloading process of the container to obtain the real-time material stratification model of the container during the second unloading process. The management device 120 then analyzes the real-time unloading information of the container during the second unloading process of the container based on the real-time morphological data of the container during the second unloading process. Furthermore, the management device 120 performs management operations on the container during the second unloading process of the container in combination with the real-time material stratification model of the container during the second unloading process and the real-time unloading information of the container.

[0082] (When M is 3) the three-dimensional measuring device 110 obtains real-time morphological data of the material during the third unloading process of the container. Then, during the third unloading process of the container, the management device 120 uses the material stratification model after the second unloading process as the initial material stratification model before the third unloading process of the container. Based on the container characteristic parameters and the material characteristic parameters of each layer in the initial material stratification model before the third unloading process of the container, the management device 120 determines the real-time unloading form of the initial material stratification model before the third unloading process of the container. Based on the real-time unloading form of the initial material stratification model before the third unloading process of the container, the management device 120 adjusts the distribution of each layer in the initial material stratification model before the third unloading process of the container to obtain the real-time material stratification model of the container during the third unloading process. The management device 120 then analyzes the real-time unloading information of the container during the third unloading process of the container based on the real-time morphological data of the third unloading process of the container. Furthermore, the management device 120 performs management operations on the third unloading process of the container by combining the real-time material stratification model of the third unloading process with the real-time unloading information of the container. This process is analogous and will not be further described.
