Description

Technical Field

[0001] The present invention relates to the technical field of coal storage management, and in particular to an intelligent storage management system for coal mines. Background Art

[0002] In today's coal mining industry, efficient and accurate storage management is crucial to the safe production and economic benefits of coal mining enterprises. With the continuous advancement of science and technology, traditional coal mine storage management methods have gradually revealed many disadvantages and are difficult to meet the development needs of modern coal mining enterprises. Traditional coal mine storage management mainly relies on manual operation, and often requires a lot of manpower in the sorting, entry and exit registration, inventory counting and other links of goods. This method is not only inefficient, but also prone to human errors, such as recording errors, loss of goods, etc. At the same time, manual management is difficult to monitor and accurately control the environment in the warehouse in real time. Factors such as temperature and humidity may affect the quality and performance of coal and related equipment. In addition, traditional storage management lacks scientificity in the classification and storage location allocation of goods. Different types of coal, equipment and accessories are often randomly stacked, which makes it difficult to quickly find the required items when needed, affecting production progress. Moreover, there is a lack of effective monitoring and management of the storage time of coal, which can easily cause the quality of coal to decline due to long-term storage, and may even cause safety hazards such as spontaneous combustion.

[0003] Although the existing intelligent coal storage management system can store different types of coal, it cannot classify and store them well according to the coal data, nor can it adjust the coal storage location in time when the coal quality decreases. For this reason, we propose a coal mine intelligent storage management system. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent storage management system for coal mines.

[0005] To achieve the above object, the present invention provides the following technical solutions: an intelligent storage management system for coal mines, the storage management system comprising a sorting module, a storage entry and exit module, an inventory management module, an early warning module and a display module; The sorting module includes a camera, a laser scanner, a hopper scale and a transfer module, wherein the laser scanner is used to scan the volume of coal placed on the conveyor belt to obtain total volume data, and the camera and the hopper scale cooperate with each other to perform further data collection. When the conveyor belt is used to transport coal, the hopper scale records the weight of the transported coal, and the camera photographs the size of the coal in the conveyor belt, and classifies the coal according to the size. Then, the transfer module is used to transfer the coal to different conveyor belts, and then the coal is transported to different storage locations. Then, the density between coal and coal is calculated, and the position of coal in different storage locations is adjusted according to different densities. The in-and-out module stores the coal data sent to the storage warehouse after classification and the coal data sent out of the storage warehouse through a conveyor belt, and then transfers the coal to the storage location at the corresponding position according to the sorting data, and transmits the coal data stored in the storage location to the inventory management module; The inventory management module is used to analyze the quality of coal. The quality of the coal in the warehouse is analyzed through sensors. Subsequently, the inventory management module will identify the coal below the quality threshold and transmit it to the corresponding processing equipment through the warehouse entry and exit module. When the sensor monitors that the data in the warehouse exceeds the monitoring threshold, the inventory management module creates an early warning instruction and transmits the early warning instruction data to the early warning module; The early warning module performs early warning processing through a self-sounding device; The display module is used to display the coal data of each storage bin in the inventory.

[0006] As a further solution of the present invention: the storage module includes a coal processing module, the sorting module includes a data processing unit, and the data processing unit obtains the coal density data through a formula, and the specific formula is as follows: ; in, Represents coal density data, Indicates the total weight of coal, Represents the total volume data of coal, The weight coefficient that represents the effect of each coal size on the coal enables the data processing unit to obtain the coal density data according to the coal of different sizes, and then the sorting module classifies the coal according to the different density data, and the classified coal is transferred to the corresponding storage location through the transfer module.

[0007] As a further solution of the present invention: the entry and exit module includes a coal processing module, which stores the time data and quantity data of coal entering and exiting different storage locations, transmits the coal data to the inventory management module, and uses the inventory management module to calculate the storage time thresholds of different coals. When the storage time of the coal exceeds the storage time threshold, the inventory management module generates a processing instruction and transmits the processing instruction to the entry and exit module. The entry and exit module transmits the corresponding timed coal to the drying processing module via a conveyor belt, and the coal processing module dries and stirs the coal.

[0008] As a further solution of the present invention: the inventory management module reprocesses and analyzes the coal after the mixing process, adjusts the storage position according to the regenerated density data of the coal, and then uses the conveyor belt and the transfer module to transport the processed coal to the storage warehouse.

[0009] As a further solution of the present invention: the inventory management module obtains the air humidity data and the bin temperature data in real time through the sensor, and then transmits the air humidity data and the bin temperature data to the display module. When the air humidity data and the bin temperature data exceed the threshold range, the inventory management module generates an early warning report, and transmits the early warning report data to the early warning module for early warning, and obtains other idle bin data through sensors and cameras. When other idle bin data are within the threshold range, the inventory management module generates a control instruction, and transmits the control instruction data to the sorting module. The sorting module uses the transfer module and the conveyor belt to transport the coal to the idle bin.

[0010] As a further solution of the present invention: the inventory management module obtains the coal storage time data according to a formula, and the specific formula is as follows: ; in, The coal quality is The storage time data of coal, The coal quality is Quality data at the time of Quality data representing the minimum threshold of coal, Data indicating the daily decline in coal quality, Represents the weight coefficient of air humidity in the coal storage environment.

[0011] As a further solution of the present invention: the inventory management module generates an adjustment instruction based on the storage time of coal. When the coal quality drops to the threshold range of other categories, the inventory management module transmits the adjustment instruction data to the entry and exit module, and uses the conveyor belt to adjust the position of the coal in the warehouse.

[0012] As a further solution of the present invention: the inventory management module includes a data storage module, which uses the data storage module to obtain historical coal storage data. The inventory management module adjusts the storage volume between different storage locations based on the historical coal storage data, and obtains the next storage weight data of coal under different qualities through a formula. The specific formula is as follows: ; in, The coal quality is The next storage weight data of coal, Indicates that the coal quality in historical data is The coal outbound weight data, Indicates that the quality of coal in historical coal is The time data from storage to delivery, It indicates the weight data of coal transmitted to the storage location due to the decline of coal quality in the historical data, and transmits the coal storage quantity to the display module so that the user can view the coal storage data through the display module.

[0013] By adopting the above technical solution, compared with the prior art, the beneficial effects of the present invention are: 1. The present invention detects coal through a sorting module, and then uses a data processing unit to analyze coal data.

[0018] Please refer to the attached Figure 1 -Attached Figure 2The present invention provides an intelligent storage management system for coal mines, the storage management system includes a sorting module, a storage entry and exit module, an inventory management module, an early warning module and a display module; The sorting module includes a camera, a laser scanner, a hopper scale and a transfer module. The laser scanner is used to scan the volume of coal placed on the conveyor belt and obtain the total volume data. The camera and the hopper scale cooperate with each other to collect further data. When the conveyor belt is used to transport coal, the hopper scale records the weight of the transported coal. At the same time, the camera shoots the size of the coal in the conveyor belt and classifies it according to the size of the coal. Then, the transfer module is used to transfer the coal to different conveyor belts, and then the coal is transported to different storage locations. The density between coal and coal is calculated, and the position of coal in different storage locations is adjusted according to different densities. The transfer module is used to facilitate the transfer of coal to different storage locations. When sorting, a sorting device can be set in the sorting module, and the sorting device can be used to sort the coal of different specifications on the conveyor belt, which effectively improves the accuracy of the coal quality stored in the warehouse, and facilitates the subsequent storage and pre-processing according to the coal quality. The laser scanner and the hopper scale cooperate with each other to obtain the density of the coal, and then determine the type of coal, which includes high-quality coal, high-quality coal and ordinary coal. Then, the transfer module is used to perform the first classification of the coal, so that the coal is transmitted to different large warehouses, and then the camera is used to obtain the block size of each coal, so that the transfer module can classify the coal again, and the coal in the large warehouse is transported to the small warehouse, so as to improve the management of coal data by the subsequent warehouse management system; The in-and-out module stores the coal data sent to the storage warehouse after classification and the coal data sent out of the storage warehouse through the conveyor belt, and then transfers the coal to the corresponding position according to the sorting data, and transmits the coal data stored in the warehouse to the inventory management module; The inventory management module is used to analyze the quality of coal. It analyzes the quality of coal in the warehouse through sensors. Then, the inventory management module will identify the coal below the quality threshold and transmit it to the corresponding processing equipment through the in-and-out module. When the sensor detects that the data in the warehouse exceeds the monitoring threshold, the inventory management module will create an early warning instruction and transmit the early warning instruction data to the early warning module.

[0019] In the first embodiment, the sorting module includes a data processing unit, and the data processing unit obtains the coal density data through a formula, and the specific formula is as follows: ; in, Represents coal density data, Indicates the total weight of coal, Represents the total volume data of coal, The weight coefficient representing the influence of each coal size on coal is used so that the data processing unit obtains the coal density data according to the coal of different sizes, and then the sorting module classifies the coal according to the different density data, and the classified coal is transmitted to the corresponding storage position through the transfer module. The storage-in and storage-out module includes a coal processing module, and the storage-in and storage-out module stores the coal in and out time data and quantity data in different storage positions, and transmits the coal data to the inventory management module. The storage time threshold of different coals is calculated by the inventory management module. When the storage time of coal exceeds the storage time threshold, the inventory management module generates a processing instruction and transmits the processing instruction to the storage-in and storage-out module. The storage-in and storage-out module transmits the corresponding timed-out coal to the drying processing module through the conveyor belt. The coal processing module dries and stirs the coal. After the coal is stored for more than a certain period of time, it becomes damp, and the density structure of the coal changes. Then, the conveyor belt is used to process the coal with the changed structure. Specifically, the coal is inspected through the sorting module, and then the coal data is analyzed by the data processing unit. The transfer module transfers the coal to different conveyor belts according to the density data of different coals, so that the conveyor belts transfer the coal to different storage locations. At the same time, the inventory management module adjusts the quantity of coal in different storage locations according to the coal quality data in the storage locations, thereby achieving the effect of the warehouse management system adjusting storage according to the coal data.

[0020] In the second embodiment, the inventory management module obtains the air humidity data and the bin temperature data in the bin in real time through the sensor, and then transmits the air humidity data and the bin temperature data to the display module. When the air humidity data and the bin temperature data exceed the threshold range, the inventory management module generates an early warning report, and transmits the early warning report data to the early warning module for early warning.

[0022] Working principle: First, the volume of the coal placed on the conveyor belt is scanned by the laser scanner in the sorting module to obtain the total data of the coal volume. When the coal is transmitted on the conveyor belt, the hopper scale records the weight of the transmitted coal, and the camera captures the size of the coal in the conveyor belt. The coal data is obtained through the data processing unit, and then the transfer module is used to transfer the coal to different conveyor belts, and then the conveyor belts are used to transport the coal to different storage locations.
