Description

Material Stratification Management System Based on Three-Dimensional Measurement Device 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 Technology

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

[0003] However, in actual production processes, many materials have a limited 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. Therefore, if multiple batches of material are already stored in a container (e.g., a storage tank) before a batch is stored, or if multiple batches need to be stored subsequently after a batch is stored, and the process of storing material into the container may involve interspersed discharge processes, existing material management equipment or methods will struggle to monitor the usage of any single batch of material. This results in low management efficiency and significant monitoring errors. Summary of the Invention

[0004] This invention provides a material stratification management system based on a three-dimensional measurement device to monitor the usage of multiple batches of materials stored in containers, thereby reducing monitoring errors and improving the management efficiency of the material stratification management system.

[0005] In a first aspect, embodiments of the present invention provide a material layering management system based on a three-dimensional measurement device, including a management device and the three-dimensional measurement device;

[0006] The three-dimensional measuring device is installed on the container and is used at least to obtain the internal morphology of the container before the first feeding of the container; and to obtain material morphology data after each feeding of the container within a time span from the first discharge of the container to the (M-1)th discharge and before the Mth discharge; and to obtain real-time morphology data of the material during each discharge process of the container.

[0008] Where M≥2, and M is a positive integer.

[0009] Optionally, the three-dimensional measuring device is further used to determine the acquisition time of the material morphology data after each feeding of the container and upload it to the management device;

[0010] The management device is also used to map the acquisition time of the material morphology data after each feeding of the container to each layer of material in the material layering model, so as to generate time management information for the material layering model.

[0011] Optionally, it may also include an alarm device;

[0012] When the time management information of at least one layer of material in the material stratification model is in an abnormal state, the management device generates an alarm command;

[0013] The alarm device is connected to the management device and is used at least to acquire and send alarm signals to the user according to the alarm command.

[0014] Optionally, it also includes:

[0015] A pre-analysis device, connected to the management device, is used at least to obtain the material characteristic parameters of each layer of materials in the initial material stratification model and upload them to the management device.

[0016] The management device is also used to map the material characteristic parameters of each layer of material to the material layering model, so as to generate other management information of the material layering model.

[0017] Optionally, the container characteristic parameters 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.

[0018] Optionally, the material characteristic parameters of each layer of material include at least one of the following: particle morphology of each layer of material, coefficient of friction between each layer of material and the container, coefficient of friction between each layer of material, particle density of each layer of material, particle shear modulus of each layer of material, particle recovery coefficient of each layer of material, humidity of each layer of material, and surface adhesion parameters of each layer of material.

[0019] Optionally, the number of the three-dimensional measuring devices is at least one.

[0020] Optionally, the three-dimensional measuring device includes at least an antenna array that can be used for digital beamforming.

[0021] Optionally, the three-dimensional measuring device includes at least a mechanical motion structure and a scanning probe. The mechanical motion structure drives the scanning probe to rotate, so that the scanning probe has multiple emission points in multiple directions and correspondingly forms multiple outgoing beams.

[0022] Optionally, the scanning probe is an antenna array that can be used for digital beamforming.

[0023] Optionally, the three-dimensional measuring device consists of at least a plurality of independent single-point measuring sub-devices;

[0024] Different single-point measuring sub-devices are installed at different locations on the container;

[0025] The single-point measurement sub-device has a single-direction wave emission point and correspondingly forms a single-direction outgoing beam.

[0026] Optionally, the three-dimensional measuring device includes at least a main body and multiple single-point measuring modules;

[0027] All single-point measurement modules are installed inside the main body of the device;

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

[0029] Secondly, embodiments of the present invention also provide a material layering management system based on a three-dimensional measuring device, including a management device and the three-dimensional measuring device;

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

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

[0032] The technical solution provided by this invention uses a three-dimensional measuring device to obtain the internal morphology of the container before the first feeding and to obtain the material morphology data after each feeding before the first discharging. Then, a management device acquires and establishes an initial material layering model before the first discharging based on the internal morphology of the container and all material morphology data before the first discharging. Furthermore, the management device determines the real-time discharging form of the initial material layering model before the first discharging based on the container's characteristic parameters and the material characteristic parameters of each layer in the initial material layering model. During the first discharging process, the three-dimensional measuring device acquires real-time material morphology data, and the management device parses the real-time discharging information based on this data. Simultaneously, the management device adjusts the distribution of each layer in the initial material layering model before the first discharging based on the real-time discharging form, obtaining the real-time material layering model for the first discharging. Finally, the management device combines the real-time material layering model and the real-time discharging information to manage the container discharging process.

[0033] (When M equals 2) The 3D measuring device acquires material morphology data after each feeding from the container during the time span from the first discharge to the second discharge. Then, based on the material stratification model after the first discharge and all material morphology data during the time span from the first discharge to the second discharge, the management device establishes an initial material stratification model before the second discharge. Furthermore, 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, the management device determines the real-time discharge pattern of the initial material stratification model before the second discharge. During the second discharge of the container, the three-dimensional measuring device acquires real-time morphological data of the material, and the management device parses the real-time morphological data to obtain the real-time discharge information of the container. At the same time, the management device adjusts the distribution of each layer of material in the initial material stratification model before the second discharge of the container based on the real-time discharge form of the initial material stratification model before the second discharge of the container, so as to obtain the real-time material stratification model of the container for the second discharge. Finally, the management device combines the real-time material stratification model and the real-time discharge information of the container to manage the container discharge process.

[0034] Similarly, (when M equals 3) the 3D measuring device acquires material morphology data after each feeding from the container during the time span from the second discharge to the third discharge. Then, based on the material stratification model after the second discharge and all material morphology data during the time span from the second discharge to the third discharge, the management device establishes an initial material stratification model before the third discharge. Furthermore, 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, the management device determines the real-time discharge pattern of the initial material stratification model before the third discharge. During the third discharge process of the container, the 3D measuring device acquires real-time morphological data of the material, and the management device parses the real-time morphological data to obtain the real-time discharge information of the container. Simultaneously, based on the real-time discharge pattern of the initial material stratification model before the third discharge, the management device adjusts the distribution of each layer of material in the initial material stratification model before the third discharge, obtaining the real-time material stratification model for the third discharge. Finally, the management device combines the real-time material stratification model and the real-time discharge information to manage the container discharge process. This process continues in a similar manner, without further elaboration.

[0035] Therefore, the material stratification management system in this embodiment of the 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 (i.e., each batch) of material in the initial material stratification model before container discharge is relatively stable. However, during the container discharge process, the real-time discharge of multiple layers of material is quite complex, and existing material management equipment or methods have low management efficiency and large monitoring errors. In view of this, during the container discharge process, this embodiment of the invention can, on the one hand, adjust the distribution of each layer of material in the initial material stratification model before each discharge by the management device based on the real-time discharge form of the initial material stratification model before each discharge, thereby obtaining the real-time material stratification model for each discharge; on the other hand, this embodiment of the invention can use a three-dimensional measurement device to obtain real-time morphological data of the material during the container discharge process (e.g., three-dimensional point cloud data of the material surface, material height data, etc.), and then parse the real-time discharge information of the container (e.g., discharge volume, discharge mass, etc.) based on the real-time morphological data; finally, by combining the real-time material stratification model and the real-time discharge information of the container, the container discharge process can be managed (e.g., after the bottom 1 ton of material in the container has been discharged, the container's discharge port can be closed in time), which helps to reduce the monitoring error of the material stratification management system and improve the management efficiency of the material stratification management system.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0044] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0045] Figure 1 is a schematic diagram of a material layering management system based on a three-dimensional measurement device according to an embodiment of the present invention. As shown in Figure 1, the material layering management system based on the three-dimensional measurement device 110 includes a management device 120 and a three-dimensional measurement device 110.

[0046] A three-dimensional measuring device 110 is installed in a container and is used at least to obtain the internal morphology of the container before the first feeding of the container; and to obtain material morphology data after each feeding of the container during the time span from the first discharge of the container to the (M-1)th discharge to the Mth discharge.

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

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

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

[0050] Depending on the application scenario, containers can be used to store only one type of material (such as carbon powder in the chemical industry) or to store multiple materials (such as various 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 the signal being blocked by obstacles such as ladders, pipes, and support structures inside the container, resulting in low measurement accuracy, or it may be limited by the angle of repose caused by the material filling level inside the container, and can only obtain local material morphology data.

[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, the number of three-dimensional measuring devices 110 may be at least one). Furthermore, before the material stratification management system is put into operation, the parameters of each three-dimensional measuring device 110 can be calibrated in advance to improve the accuracy of container internal morphology, material morphology data, real-time morphology data, etc.

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

[0054] For example, the working principle of a material stratification management system can be described as follows:

[0055] The three-dimensional measuring device 110 obtains the internal morphology of the container before the first feeding and acquires material morphology data after each feeding before the first discharging. Then, the management device 120 acquires and establishes an initial material layering model before the first discharging based on the internal morphology of the container and all material morphology data before the first discharging. Furthermore, the management device 120 determines the real-time discharging form of the initial material layering model before the first discharging based on the container's characteristic parameters and the material characteristic parameters of each layer in the initial material layering model before the first discharging. During the first discharge of the container, the three-dimensional measuring device 110 acquires real-time morphological data of the material (e.g., three-dimensional point cloud data of the material surface, material height data, etc.). The management device 120 parses the real-time discharge information of the container based on the real-time morphological data of the material (e.g., discharge volume, discharge mass, etc.). At the same time, the management device 120 adjusts the distribution of each layer of material in the initial material stratification model before the first discharge of the container based on the real-time discharge form of the initial material stratification model before the first discharge of the container, and obtains the real-time material stratification model of the container for the first discharge. Finally, the management device 120 combines the real-time material stratification model and the real-time discharge information of the container to manage the discharge process of the container (e.g., after the bottom 1 ton of material in the container is discharged, the discharge valve of the container, belt weighing and conveying system, etc. are closed in time).

[0056] (When M equals 2) The three-dimensional measuring device 110 acquires material morphology data after each feeding of the container during the time span from the first discharge to the second discharge. Then, the management device 120 establishes an initial material stratification model before the second discharge based on the material stratification model after the first discharge and all material morphology data during the time span from the first discharge to 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 characteristic parameters and the material characteristic parameters of each layer of material in the initial material stratification model before the second discharge. During the second discharge of the container, the three-dimensional measuring device 110 acquires 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 discharge form of the initial material stratification model before the second discharge of the container, and adjusts the distribution of each layer of material in the initial material stratification model before the second discharge of the container to obtain the real-time material stratification model of the second 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.

[0057] (When M equals 3) The three-dimensional measuring device 110 acquires material morphology data after each feeding of the container during the time span from the second discharge to the third discharge. Then, the management device 120 establishes an initial material stratification model before the third discharge based on the material stratification model after the second discharge and all material morphology data during the time span from the second discharge to the third discharge. 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 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 measuring device 110 acquires real-time material morphology data, and the management device 120 parses the real-time discharge information of the container based on the real-time discharge pattern of the initial material stratification model before the third discharge, and adjusts the distribution of each layer of material in the initial material stratification model before the third discharge to obtain the real-time material stratification model of the container for the third discharge; finally, the management device 120 manages the container discharge process by combining the real-time material stratification model and the real-time discharge information of the container. (When M equals 4) The 3D measuring device 110 acquires material morphology data after each feeding of the container during the time span from the third discharge to the fourth discharge. Then, the management device 120 establishes the initial material stratification model before the fourth discharge of the container based on the material stratification model after the third discharge and all material morphology data during the time span from the third discharge to the fourth discharge. Furthermore, the management device 120 determines the real-time discharge form of the initial material stratification model before the fourth discharge based on the container's characteristic parameters and the material characteristic parameters of each layer in the initial material stratification model before the fourth discharge. During the fourth discharge process, the three-dimensional measurement device 110 acquires real-time material morphology data, and the management device 120 parses the real-time discharge information of the container based on the real-time morphology data. Simultaneously, the management device 120 adjusts the distribution of each layer of material in the initial material stratification model before the fourth discharge based on the real-time discharge form of the initial material stratification model before the fourth discharge, obtaining the real-time material stratification model for the fourth discharge. Finally, the management device 120 manages the container discharge process by combining the real-time material stratification model and the real-time discharge information. This process continues in a similar manner, without further elaboration.

[0058] In summary, the material stratification management system in this embodiment of the invention can monitor the usage of multiple batches of materials stored in containers 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 container discharge is relatively stable. However, during container discharge, the real-time discharge of multiple layers of material is complex, resulting in low management efficiency and large monitoring errors in existing material management equipment or methods. Therefore, during container discharge, this embodiment of the invention, on the one hand, can adjust the distribution of each layer of material in the initial material stratification model before each discharge by using a management device based on the real-time discharge pattern of the initial material stratification model before each discharge, thus obtaining a real-time material stratification model for each discharge; on the other hand, this embodiment of the invention can use a three-dimensional measurement device to acquire real-time morphological data of the material during the container discharge process, and then parse the real-time morphological data to obtain real-time container discharge information; finally, by combining the real-time material stratification model and the real-time container discharge information, the container discharge process can be managed, which helps to reduce the monitoring error of the material stratification management system and improve its management efficiency.

[0059] It should be noted that, depending on the type of signal transmitted and received, 3D measurement devices can specifically include 3D microwave radar, 3D lidar, etc. Understandably, when materials are fed into or discharged from containers, especially powdery solid materials, the material level and the three-dimensional morphology of the material surface fluctuate constantly, generating a large amount of dust and smoke. Under these harsh measurement conditions, the laser signals transmitted and received by 3D lidar are easily obscured by dust and smoke, making reliable measurement difficult. However, 3D microwave radar, which operates based on microwave measurement principles, is almost unaffected by dust and smoke. Therefore, to ensure good detection and measurement accuracy during container loading and unloading, 3D microwave radar is the preferred choice.

[0060] Furthermore, based on various measurement principles, the three-dimensional measurement device can be, for example, a 3D scanning radar or a 3D multi-point radar. In one embodiment of the present invention, the three-dimensional measurement device can be a phased array 3D scanning radar; optionally, the three-dimensional measurement device includes at least an antenna array that can be used for 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 of the present invention, the three-dimensional measuring device can be a purely mechanical 3D scanning radar. Optionally, the three-dimensional measuring device includes at least a mechanical motion structure and a scanning probe. The mechanical motion structure drives the scanning probe to rotate, so that the scanning probe has multiple emission points in multiple directions and correspondingly forms multiple outgoing beams in multiple directions. The mechanical motion structure can have multiple motion dimensions in multiple directions (e.g., horizontal, pitch, vertical, etc.), the scanning probe can be a microwave sensor, a laser sensor, etc., and the outgoing beams can be microwave signals, laser signals, etc.

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

[0063] In another embodiment of the present invention, the three-dimensional measuring device may 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 measuring sub-devices (e.g., single-point lidar, single-point microwave radar, etc.), with different single-point measuring sub-devices installed at different positions on the container. Each single-point measuring sub-device has a single-direction emission point and correspondingly forms a single-direction output beam.

[0064] In another embodiment of the present invention, the three-dimensional measuring device may be a 3D multi-point radar; optionally, the three-dimensional measuring device includes at least a device body (e.g., it may be composed of a shell and a cover) and multiple single-point measuring modules (e.g., laser sensors, microwave sensors, etc.); the single-point measuring modules are all installed inside the device body; the single-point measuring module has a single-direction emitting point and correspondingly forms a single-direction outgoing beam.

[0065] It should also be noted that during the actual discharge process of materials inside the container, the discharge process of each layer of material is not entirely the same due to factors such as the container's geometry, the shape and size of the material particles, etc., under the influence of their own weight, the friction between materials, and the friction between materials and the container.

[0066] For example, Figure 2 is a schematic diagram of the discharge state of a container provided by an embodiment of the present invention, Figure 3 is a schematic diagram of the discharge state of another container provided by an embodiment of the present invention, and Figure 4 is a schematic diagram of yet another discharge state of a container provided by an embodiment of the present invention. Referring to Figure 2, for a container with a single discharge port, its discharge process can generally be divided into two stages; in the initial stage of discharge, the discharge form of the material located at the bottom of the container is in the form of a "funnel", 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 materials 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". As shown in Figures 3 and 4, unlike a container with a single discharge port, the discharge situation of a container with multiple discharge ports (Figures 3 and 4 exemplarily show a container with two discharge ports) is related to the opening and closing state of the discharge ports. Referring to Figure 3, when the opening and closing states of each discharge port are consistent, the container can basically achieve balanced discharge, meaning that the stratification of materials in each layer of the container remains almost unchanged, and the material descends as a whole. Referring to Figure 4, when the opening and closing states of each discharge port are inconsistent, the material near the discharge port with the larger opening descends faster.

[0067] Therefore, in some embodiments, optionally, the container characteristic parameters 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, coefficient of friction between each layer of material and the container, coefficient of friction between each layer of material, particle density of each layer of material, particle shear modulus of each layer of material, particle recovery coefficient of each layer of material, moisture content 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 parameter of a container with a conical structure, the discharge port size parameter, and the size parameter of the container body; the degree of opening and closing of the discharge port during the container discharge process may be, for example, fully open, half open, or closed.

[0068] Based on the above embodiments, Figure 5 is a schematic diagram of another material layering management system based on a three-dimensional measurement device provided by an embodiment of the present invention. As shown in Figure 5, optionally, the three-dimensional measurement device 110 is further used to determine the acquisition time of material morphology data after each feeding of the container and upload it to the management device 120; the management device 120 is further used to map the acquisition time of material morphology data after each feeding of the container to each layer of material in the material layering model, so as to generate time management information for the material layering model.

[0069] Optionally, it also includes an alarm device 130; when the time management information of at least one layer of material in the material stratification model is in an abnormal state, the management device 120 generates an alarm command (e.g., a wired signal or a wireless signal); the alarm device 130 is connected to the management device 120 and is used at least to acquire and send an alarm signal to the user according to the alarm command.

[0070] Optionally, it also includes: a pre-analysis device 140, connected to the management device 120, for at least obtaining the material characteristic parameters of each layer of materials in the initial material stratification model and uploading them to the management device 120; the management device 120 is also used to map 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] Material morphology data may include a three-dimensional shape diagram of the material, the highest material level, the lowest material level, the average material level, the material volume, and the material mass.

[0072] For example, the management device 120 can determine the expiration time of each layer of material based on the feeding time of each layer of material in the material layering model (for example, the expiration time of carbon powder is the feeding time plus 15 days). When one or more layers of material are about to expire (for example, the day before the expiration time), the management device 120 controls the alarm device 130 (for example, buzzer, warning light, warning sign, 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 multiple layers of material, that is, the thickness information of a certain layer of material in a certain vertical direction.

[0073] The pre-analysis device 140 may include a testing platform, belt scale, densitometer, hygrometer, etc. For example, the hygrometer can be used to obtain the humidity of each layer of material; the testing platform can be used to obtain the particle morphology of each layer of material, the coefficient of friction between each layer of material and the container, the coefficient of friction between each layer of material, the particle density of each layer of material, the particle shear modulus of each layer of material, the particle recovery coefficient of each layer of material, and the surface adhesion parameters of each layer of material. 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 composition content management information based on the material stratification model and the composition content of each layer of material, etc.

[0074] Therefore, the material stratification management system in this embodiment of the invention can 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 pre-analytical devices such as testing platforms, belt scales, densitometers, and hygrometers to adaptively obtain parameters such as the type, content, composition, origin, quality, density, and humidity of each layer of material, and assign these 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] Meanwhile, because solid materials have low compressibility, the morphology of each layer (i.e., each batch) of material in the initial material stratification model before container discharge is relatively stable. However, during container discharge, the real-time discharge of multi-layered materials is quite complex, and existing material management equipment or methods have low management efficiency and large monitoring errors. In view of this, during container discharge, this embodiment of the invention can, on the one hand, adjust the distribution of each layer of material 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 by the management device, thereby obtaining the real-time material stratification model for each container discharge; on the other hand, this embodiment of the invention can use 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 discharge information of the container based on the real-time morphological data; finally, by combining the real-time material stratification model and the real-time discharge information of the container, the container discharge process can be managed, which helps to reduce the monitoring error of the material stratification management system and improve the management efficiency of the material stratification management system.

[0076] In actual production, if the "shelf life" of materials (such as grains) is long and frequent unloading is not required, the following technical solutions can be adopted to monitor the usage of multiple batches of materials stored in containers, which helps to reduce the monitoring error of the material stratification management system and improve the management efficiency of the material stratification management system.

[0077] Based on the foregoing embodiments or implementation methods, and continuing to refer to Figure 1, the material layering management system based on the three-dimensional measurement device includes a management device 120 and a three-dimensional measurement 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 and second preset time periods can be adapted to the actual site conditions); the three-dimensional measuring device 110 is used at least to obtain the internal shape of the container before the first feeding; and to obtain the feeding shape data of the material after each feeding within the first preset time period; and to obtain the real-time shape data of the material during each discharging process within the second preset time period.

[0079] The management device 120 establishes a communication connection with the three-dimensional measurement device 110, and is at least used to acquire and establish an initial material stratification model of the container based on the internal morphology of the container and the feeding morphology data of the material after each feeding within a first preset time period; and to 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, during the first discharge process of the container, to 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 to parse the real-time discharge information of the container based on the real-time morphology data, and then combine the real-time material stratification model with... The real-time discharge information of the container is used to manage the container discharge process. In the Mth discharge process of the container, the material stratification model after the (M-1)th discharge is used as the initial material stratification model before the Mth discharge. Based on the container characteristic parameters and the material characteristic parameters of each layer of material in the initial material stratification model, the real-time discharge form of the initial material stratification model is determined. Based on the real-time discharge 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. The real-time discharge information of the container is parsed from the real-time morphological data. Then, the real-time material stratification model and the real-time discharge information of the container are combined to manage the container discharge process.

[0080] Specifically, the 3D measuring device 110 obtains the internal morphology of the container before its initial feeding and acquires data on the material feeding morphology after each feeding within a first preset time period. Then, the management device 120 acquires and establishes an initial material layering model of the container based on the internal morphology and the material feeding morphology data after each feeding within the first preset time period. Furthermore, the management device 120 determines the real-time discharge pattern of the initial material layering model based on the container's characteristic parameters and the material characteristic parameters of each layer in the initial material layering 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 layering model based on the real-time discharge pattern, obtaining a real-time material layering model. It then parses the real-time discharge information of the container based on the real-time morphology data and performs management operations on the container's discharge process by combining the real-time material layering model and the real-time discharge information.

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

[0082] (When M equals 3) The three-dimensional measuring device 110 obtains real-time morphological data of the material during the third discharge process of the container. Then, during the third discharge process of the container, the management device 120 uses the material stratification model after the second discharge as 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, the management device 120 determines the real-time discharge form of the initial material stratification model before the third discharge. Based on the real-time discharge form of the initial material stratification model before the third discharge, the management device adjusts the distribution of each layer in the initial material stratification model before the third discharge to obtain the real-time material stratification model for the third discharge process. The management device then parses the real-time discharge information of the container based on the real-time morphological data of the third discharge process and performs management operations on the third discharge process of the container by combining the real-time material stratification model and the real-time discharge information. This process continues in a similar manner, without further elaboration.
