Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of this application, unless otherwise specified, "plurality" means two or more.

[0022] The inventor of the present invention has found that with the continuous and in-depth development of industrialization, coal, as an important energy resource, plays a key role in many industries. Especially in the power, steel, chemical and other industries, the production, transportation, storage and utilization of coal have an important impact on the production efficiency and economic benefits of enterprises. However, the traditional coal yard management method still faces many problems, including cumbersome manual operation, low management efficiency, unreasonable coal storage, and difficulty in monitoring. These problems not only affect the production efficiency of the coal yard, but also increase operating costs and may even cause safety hazards. At present, the management of the coal yard mainly relies on manual monitoring and traditional manual recording methods, lacking accurate data collection and real-time monitoring means. Especially in the storage and stacking of coal piles, traditional management methods are difficult to achieve effective dynamic scheduling and precise control, resulting in unreasonable distribution of coal piles and improper use of storage space. Based on this, in the embodiment of the present invention provided by the inventor, the unreasonable distribution of coal piles and improper use of storage space are solved through the collaborative work of the coal feeding management module, the coal pan module, and the central control module.

[0023] like Figure 1-Figure 2 As shown, a digital coal yard management and control system provided by an embodiment of the present application includes: a coal entry management module 1, a coal panning module 2 and a central control module; the coal entry management module 1 is used to collect the data of the coal entering the plant and transmit it to the central control module; the coal panning module 2 includes a coal panning device, which is used to collect the three-dimensional model data of the coal pile and transmit it to the central control module; the central control module includes a partition management module 31, a central control unit 32 and a three-dimensional display module 33; the partition management module 31 is used to: divide the coal yard into at least two partitions, and transmit the partition data to the central control unit 32; manage the stacking and removal strategies of the coal pile, according to the type of coal, coal quality, coal quantity, etc. factors, dynamically adjust the position and stacking order of the coal pile; the partition management module 31 is connected to the coal feeding management module 1; the coal feeding module transports the incoming coal to the coal pile of the corresponding partition according to the incoming coal data; the central control unit 32 is connected to the coal tray module 2, for receiving the three-dimensional model data of the coal pile and generating a three-dimensional model of the coal pile; the central control unit 32 is connected to the coal feeding management module 1, for receiving the incoming coal data and associating it with the partition data; the central control unit 32 is connected to the three-dimensional display module 33, and transmits the associated data to the three-dimensional display module 33; the three-dimensional display module 33 is used to display the three-dimensional map of the coal pile in each partition, and display the real-time status of each partition.

[0024] In the embodiment of the present application, the coal yard data such as the type, size, capacity, stacking and retrieval method, coal type, coal quality, coal quantity, material retrieval requirements, storage time, etc. are first stored in the central control unit 32, and the partition management module 31 queries the central control unit 32 to obtain the coal yard factor data, and then partitions the coal yard. For example, the coal yard is a square coal yard with an area of ​​10,000 square meters, a length and width of 100 meters, and the coal yard is divided into an entrance area, a high-quality coal area, a medium-quality coal area, a low-quality coal area, a coal area to be retrieval, a safety management area, and a temporary storage area. The area of ​​the entrance area A is 1500 square meters, which is mainly used to receive coal entering the factory. The entrance area is equipped with a coal entry management module 1, and the coal entry management module 1 weighs, accepts, detects coal quality, and allocates coal types in this area. After the coal enters the factory, it will be guided to different partitions according to the coal type and quality after preliminary inspection and allocation. The area of ​​the high-quality coal area B is 2000 square meters, which is used to store coal with good coal quality and high price. The coal piles in this area are required to be neatly stacked and easy to access. Due to the good quality of the coal, more sophisticated management and automated control can be adopted. Division basis: good coal quality, fewer batches, and short storage time. The area of ​​Zone C of the medium-quality coal area is 2,000 square meters, which is used to store coal with better coal quality but not as good as Zone B. Due to the moderate quality, it can be stored for a long time and is suitable for future stable production needs. Division basis: medium coal quality, moderate storage time, and relatively low access requirements. The area of ​​Zone D of the low-quality coal area is 1,500 square meters, which is used to store coal with poor coal quality and low combustion efficiency. The coal piles in this area usually require more stringent management to avoid oxidation, deterioration and other problems caused by long-term accumulation. Coal with poor coal quality is generally used first in certain low-requirement production links. Division basis: poor coal quality, long storage time, and easy oxidation. The area of ​​Zone E of the waiting area is 1,000 square meters, which is specially used to store the coal piles to be accessed. The coal in this area is usually stored and retrieved according to orders or production needs. The management of this area pays more attention to the efficiency and convenience of access operations. Division basis: Coal piles that need to be taken out in time are divided according to the material taking demand. Safety management area F area covers an area of ​​800 square meters and is used to store potentially dangerous or high-temperature coal piles, as well as other coal piles that require special management, such as coal piles with higher fire risks. Division basis: Coal piles are stacked high and there is a greater risk of fire or oxidation. Temporary storage area G area covers an area of ​​600 square meters and is used to store coal piles that are temporarily unallocated or need further processing. This area is generally used for short-term storage and rapid allocation. Division basis: Coal piles have not been allocated in time or are waiting for processing.

[0025] After the zoning is completed in the above manner, the zoning needs to be managed. Since the area of ​​a single zoning is relatively large, it is also necessary to divide the coal piles into each zoning. The factors for the division include: coal type, coal quality, storage time, etc. In the high-quality coal area, the thermal coal with the best quality is piled near the exit of the high-quality coal area to facilitate rapid discharge. High-quality coking coal is piled separately, and the quality is marked and numbered. In the specific usage scenario, if the incoming coal is found to be of good quality and is coking coal after testing, it will be allocated to area B first, and then a coal pile will be selected in area B for stacking. At this time, if the coking coal has been piled in a coal pile before, it can continue to be piled; if it has not been piled before, select one of the idle coal piles for stacking.

[0026] After the zoning and stacking are completed, the system will automatically adjust the position and stacking order of the coal pile according to the real-time data in the partition, such as coal type, coal quality, coal quantity, etc., and remind the management personnel to make timely adjustments through the system. The stacking and material retrieval strategies are as follows: Area B, high-quality coal area: give priority to meeting production needs, and dispatch according to coal quality priority and production plan sequence when retrieving materials. Area D, low-quality coal area: give priority to retrieval, reduce the storage time of low-quality coal piles, and avoid further deterioration of coal quality. Area F, safety management area: closely monitor and detect dangerous situations such as fire in time to ensure safety. Area E, waiting area for retrieval: adjust the stacking order according to real-time retrieval needs to reduce ineffective retrieval operations.

[0027] In addition, the partition management module 31 also needs to pay attention to changes in coal storage, coal quality, coal type, etc. Specifically, coal storage change management: when the central control unit 32 finds that the coal storage in a certain partition is close to the maximum storage capacity based on the comparison between the coal storage in the partition and the storage capacity of the partition, the information is synchronized to the central control unit 32, and the partition management module 31 notifies the staff to adjust the coal stacking method according to the change in coal storage, such as optimizing the stacking layout to avoid excessive concentration of coal piles and improve the utilization rate of storage space. Optionally, new coal piles can also be restricted from entering the partition. Coal quality change management: In a possible implementation, an acceptance device is provided in each partition of the coal yard, which will detect the coal quality in real time and transmit the results to the central control unit 32. When the coal quality changes, the partition management module 31 notifies the staff to adjust the storage location, processing sequence or acceptance criteria of the coal pile to ensure that the coal quality meets the management requirements and avoid low-quality coal piles affecting the entire coal yard. Coal type change management: When the coal input management module 1 collects coal type changes, the partition management module 31 will dynamically adjust the stacking order according to the characteristics of different coal types, giving priority to certain coal types to meet market demand or production needs. The coal stacking device and the material taking device will also adjust the stacking and material taking order according to the coal type changes to ensure that there is no conflict between the stacking and coal taking of different coal types.

[0028] It should be noted that after the zoning and stacking are completed and the coal entering the factory is stacked, the deployed coal pan device performs continuous cross-sectional scanning of the coal pile by laser scanning, radar, photogrammetry, etc. to obtain point cloud data on the surface of the coal pile. The data is sent to the central control unit 32, and the data processing module needs to align the data at different scanning positions through point cloud registration technology. Common registration methods include feature-based matching or ICP algorithm, which merges point cloud data of different sections into an overall three-dimensional point cloud. For low-density areas, interpolation algorithms such as nearest neighbor interpolation and spline interpolation are used to densify the point cloud to make the point cloud data on the surface of the coal pile more refined and avoid missing models. The point cloud data is converted into a three-dimensional surface model using a triangular mesh reconstruction algorithm such as Delaunay triangulation and Poisson surface reconstruction. This step forms a closed surface by constructing triangular facets between point clouds. The generated three-dimensional model may contain a large number of triangular facets, and the amount of calculation is large. The model is optimized by a mesh simplification algorithm such as the QEM algorithm to reduce the number of facets while maintaining a high visual accuracy.

[0029] After the central control unit 32 completes the construction of the coal pile model, it associates it with the partition data, such as the partition number and partition name, and finally transmits the data to the three-dimensional display module 33. Through the display of the three-dimensional display module 33, the distribution and real-time status of the partitioned coal pile can be intuitively observed.

[0030] The data of coal entering the factory include coal type, coal quantity, coal quality, coal price, batch, etc.; the basis of division includes: coal yard type, coal type, coal quality, coal quantity, storage time; partition data includes: partition number, partition name, storage capacity, number of coal piles that can be accommodated, coal pile number; real-time status includes coal inventory, coal quality, and coal price in the coal yard.

[0031] By adopting the above technical solution, the space of the coal yard is reasonably allocated and managed through zoning management, so that the coal pile is reasonably distributed and the storage space is properly utilized, which improves the storage efficiency of the coal yard; and it can adapt to the needs of taking different types of coal, reducing unnecessary accumulation, mixing or difficulty in taking materials. Through the cooperation of the coal entry management module 1, the coal pan module 2 and the central control module, the automation of the coal yard management process is realized, including the collection, distribution and stacking of incoming coal. The three-dimensional display module 33 can display the three-dimensional image of the coal pile based on the real-time transmitted data, and provide the status information of the coal pile in each partition. It can help managers intuitively understand the distribution of coal piles inside the coal yard, and can also monitor the real-time status of the coal yard at any time.

[0032] In a possible implementation, the central control module includes a coordinate establishment module 34, which is used to establish a unified three-dimensional coordinate system for the coal yard space and transmit the three-dimensional coordinate data to the central control unit 32; the central control unit 32 is connected to the coordinate establishment module, and is used to store the three-dimensional coordinate data and transmit it to the partition management module 31; the partition management module 31 uses the three-dimensional coordinate data as a basis for dividing the coal yard into partitions; the partition data includes: partition position, and the partition position is expressed in the form of three-dimensional coordinates.

[0033] By adopting the above technical solution and using the three-dimensional coordinate system, the coal pile can be better spatially scheduled and optimized, congestion and inconvenience in coal extraction can be reduced, and operational efficiency can be improved. After the three-dimensional coordinate data is transmitted to the central control unit 32, each module such as partition management, stacking and retrieving operations can obtain information such as the location and spatial layout of the coal pile in real time, realizing data sharing and linkage between systems.

[0034] In a possible implementation, the three-dimensional display module 33 includes a graphics processing unit, which introduces a three-dimensional graphics engine to support the rotation, scaling and translation operations of the three-dimensional image of the coal pile.

[0035] In the embodiment of the present application, to realize the rotation, scaling, and translation of three-dimensional graphics, modern three-dimensional graphics engines and interactive designs can be used. First, a suitable three-dimensional graphics engine is selected. In order to realize efficient three-dimensional graphics operations, three-dimensional graphics engines such as Unity3D, Unreal Engine, or Three.js can be selected. They support rich graphics display and interactive functions, and can easily handle operations such as rotation, scaling, and translation. Then, the above-mentioned three-dimensional graphics engine is used to realize the realization of rotation, scaling, and translation operations. The engine provides a rotation matrix or Euler angle to control the rotation of objects or perspectives. Therefore, rotation can be achieved by dragging the mouse, touch screen gestures, or keyboard shortcuts. The zoom operation is achieved by the mouse wheel, touch screen double-finger zoom, or keyboard shortcuts. When zooming, a certain viewing distance range must be maintained to prevent the user from zooming in or out too much, resulting in unclear graphics display. The translation operation is usually achieved by dragging the right mouse button or the arrow keys on the keyboard. By changing the translation amount of the view, the user can view the entire coal yard from different angles. The translation operation can also be used in conjunction with zooming to provide a smoother visual experience.

[0036] By adopting the above technical solution, the rotation, zooming and translation operations of the three-dimensional graphics of the coal pile are supported. Users can freely view different perspectives and details according to their needs and quickly judge and solve management problems.

[0037] In a possible implementation, the coal-incoming management module 1 includes a scanning device, an acceptance device, and a weighing device connected in sequence; the scanning device is used to scan the RFID tag or barcode on the coal transport vehicle entering the factory, collect the type of coal, coal price, batch, and number the batch of coal entering the factory; the acceptance device is used to detect whether the coal quality meets the standard; the weighing device is used to weigh the coal entering the factory to obtain the coal quantity; the coal-incoming management module 1 transmits the above-mentioned coal entering the factory data to the central control unit 32, and the central control unit 32 receives and stores the coal entering the factory data.

[0038] By adopting the above technical solution, the system can efficiently and accurately collect various information of incoming coal by automatically scanning RFID tags or barcodes, reducing manual intervention and errors. Through acceptance devices and weighing devices, it is ensured that the incoming coal meets the quality standards and is accurately measured to avoid excessive or unqualified coal from entering the coal yard.

[0039] In a possible embodiment, the system includes a stacking and retrieving module 4, which includes a control center, a stacking device and a retrieving device; the control center is used to control the stacking device to stack coal and control the retrieving device to take coal according to a preset stacking and retrieving strategy; the stacking device automatically records the coal pile number, and transmits the stacking result and stacking data to the central control unit 32; the stacking data includes: stacking position coordinates, pile shape data, coal quantity data, etc. The retrieving device automatically records the coal pile number and transmits the coal retrieving data to the central control unit 32; the coal retrieving data includes the coal retrieving quantity, coal pile position coordinates, and coal type.

[0040] By adopting the above technical solution, by automatically recording the stacking location and pile shape data, the distribution of coal piles can be understood in real time, the space utilization of the coal yard can be optimized, and excessive or disorderly stacking can be avoided. By accurately recording the number and location of the coal pile, the system can quickly and accurately carry out coal extraction operations, improving the efficiency of coal yard operations.

[0041] In a possible implementation manner, the stacking and reclaiming module 4 further includes a safety anti-collision module, which is used to initiate detection of surrounding obstacles and obtain corresponding obstacle distance and orientation information.

[0042] By adopting the above technical solutions and the intelligent anti-collision system, the stacker-reclaimer can operate more flexibly and efficiently, avoiding downtime and repair time caused by collisions. At the same time, it can also reduce equipment failures and repair costs and extend the service life of the equipment.

[0043] In a possible embodiment, the system also includes a safety monitoring module 5, which includes a temperature measuring device, a dust concentration monitoring device, a gas monitoring device and an alarm device; the temperature measuring device includes a scanning temperature measuring device and an inserted temperature measuring device, the temperature measuring device is used to measure the temperature data of the coal pile and transmit it to the central control unit 32, the dust device includes a dust concentration sensor, the dust concentration sensor is used to measure the dust concentration data of the coal yard and transmit it to the central control unit 32, the gas monitoring device includes a harmful gas monitoring device, the harmful gas device is used to measure the harmful gas data of the coal yard and transmit it to the central control unit 32; the central control unit 32 compares and judges the transmitted temperature data, dust concentration data, and harmful gas data according to the preset threshold value. If the threshold value is exceeded, the central control unit 32 controls the alarm device to alarm.

[0044] By adopting the above technical solution, the safety status of the coal yard can be grasped in real time by continuously monitoring the temperature, dust concentration and harmful gas concentration of the coal pile. Once abnormal data such as excessive temperature or excessive dust concentration appears, the system will automatically alarm, detect potential risks in advance and prevent accidents. Ensure that operators work in a safe environment and reduce the probability of safety accidents such as fire and explosion in the coal yard.

[0045] In a possible implementation, the central control unit 32 is used to store the received temperature data, dust concentration data and harmful gas data, and transmit these data to the three-dimensional display module 33; the three-dimensional display module 33 displays the temperature, dust concentration and harmful gas concentration data of the coal pile based on the three-dimensional model of the coal pile; provides coal pile status information in a visual manner, and supports real-time monitoring of coal yard safety management.

[0046] By adopting the above technical solutions and displaying safety data in 3D visualization, managers can quickly analyze the status of coal piles, provide support for scheduling and safety decisions, and improve decision-making efficiency. Through data visualization, potential safety hazards can be discovered in a timely manner, the probability of accidents such as fire and explosion in coal yards can be reduced, and the safety of coal yard workers and facilities can be protected.

[0047] In a possible embodiment, the coal panning module 2 includes but is not limited to multi-point fixed coal panning, rail-mobile coal panning, mobile stacking and reclaiming equipment, bucket wheel machine-mounted coal panning, drone-mobile coal panning and other coal panning operation modes.

[0048] In the embodiments of the present application, the fixed coal panning regularly collects the shape, volume and height data of the coal pile by installing a laser scanning device at a fixed position. In the track-mobile coal panning, the equipment is installed on the track, and the track moves to cover all areas of the coal yard to scan and collect the three-dimensional information of the coal pile. The drone coal panning uses a laser scanner carried by the drone to flexibly scan the spatial shape and surface features of the coal pile, which is suitable for rapid inventory of large-area coal yards. The mobile stacking and reclaiming equipment is divided into the front end installation method of the boom and the highest point installation method of the center column.

[0049] By adopting the above technical solutions and introducing a variety of coal-laying operation methods, the coal yard operation method is made more flexible, and the most suitable coal-laying method can be selected according to the scale of the coal yard, the operating environment and the operating requirements. Different types of coal-laying operation methods can help the coal yard use limited space more efficiently, optimize the stacking method and operation process of the coal pile, and avoid unreasonable or unscientific coal stacking problems. By introducing automated coal-laying methods such as drones and bucket wheel excavators, manual intervention can be reduced, operating efficiency and safety can be improved, and intelligent management of the coal yard can be supported.

[0050] Working principle of the embodiment of the present application: The zoning management module 31 now divides and stacks the coal yard according to the coal storage yard situation. After the pre-zoning and stacking is completed, when the incoming coal enters the coal yard, it first passes through the scanning device in the coal management module 1 to scan the RFID tag or barcode on the incoming coal transport vehicle to obtain relevant coal type, coal price, batch and other information. Then, the quality indicators of the incoming coal, such as coal quality, moisture, ash content, etc., are tested by the acceptance device to ensure that the coal meets the use standards. If the test results are unqualified, the batch of coal will not be accepted or reprocessed. After the coal quantity data is obtained by weighing, it is transmitted to the central control unit 32 together with other data.

[0051] The central control unit 32 divides the transported coal into corresponding areas for stacking according to the incoming coal data. After stacking, the coal panning device scans the partitioned coal pile, obtains the three-dimensional model data and transmits it to the central processing unit. After the central control unit 32 completes the model construction of the coal pile, it associates it with the partition data, such as the partition number and partition name, and finally transmits the data to the three-dimensional display module 33. The distribution and real-time status of the partitioned coal pile can be intuitively observed through the display of the three-dimensional display module 33. The stacking and reclaiming system executes the stacking and reclaiming plan and completes the operation with the support of safety protection and video surveillance. The safety monitoring system collects environmental data in real time to ensure operation safety. The coal panning system dynamically updates the coal pile data, and the safety monitoring module 5 ensures operation safety.

[0052] In the several embodiments provided in the present application, it should be understood that the disclosed systems, modules and methods can be implemented in other ways. For example, the module embodiments described above are only schematic, for example, the division of units is only a logical function division, and there may be other division methods in actual implementation, such as multiple units or components can be combined or integrated into another system, or some features can be ignored or not executed.
