In recent years, in order to reduce environmental pollution and transportation costs during coal transportation, transportation methods such as trucks, trains, or long-distance belt conveyors are mostly used. At the same time, in order to utilize the characteristics of different coal qualities, improve the cascade utilization efficiency of coal, and save energy, coal storage and distribution parks and shipping stations have been built in many places to achieve the mixed distribution and transportation of large quantities of coal materials.

[0014] An intelligent coal storage, distribution, loading and unloading method allowing for cross-operation, using an intelligent coal storage, distribution, loading and unloading system allowing for cross-operation, includes the following steps: 1) When coal arrives by train, after the incoming coal train enters the factory area and passes through the vehicle intelligent identification and positioning system for incoming coal trains and the on-line detection system for incoming coal trains, the vehicle information and coal quality conditions are uploaded to the central control system in real time. Then, the train carriages are transported to the train coal unloading bunker by the multi-car shunting facility. According to the prompt of the train coal unloading bunker position positioning and display system, the train coal unloading facility unloads the coal into the corresponding first independent coal storage bin in the train coal unloading bunker. When the intelligent perception system for the coal level in the train coal unloading bunker monitors that the coal stacking height in a certain first independent coal storage bin reaches the set height, the central control system controls the impeller feeder to move to the corresponding first independent coal storage bin through the positioning control system for the impeller feeder under the train coal unloading bunker, and together with the train coal unloading bunker coal return belt conveyor, the discharging chute, the transfer belt conveyor and the discharging chute, transfers the coal to the first coal blending belt conveyor. Through the combined action of the positioning control system for the discharging facilities of the first coal blending belt conveyor, the intelligent perception system for the yard boundary and coal pile height, and the yard position positioning and display system, the first discharging facility is moved to the corresponding independent yard position in the coal yard, and the coal is unloaded into the corresponding yard, realizing that coals of different qualities in a train are unloaded into different independent coal bins. This process is repeated. After the train has unloaded all the coal, the empty car leaves the factory area or travels to the train quantitative loading system for loading and transporting the coal out. 2) When coal arrives by truck, after entering the plant, the truck passes through the intelligent identification and positioning system of the incoming coal truck, the heavy truck weighing device in the empty and loaded truck weighing system, and the online detection system for incoming coal, and then uploads the vehicle information, heavy truck weight and coal quality to the central control system in real time. Then, the truck drives to the truck unloading coal bunker and unloads the coal into the corresponding second independent coal storage bunker according to the prompt of the truck unloading coal bunker position positioning display system, so that coal of different coal qualities can be unloaded into different second independent coal storage bunkers, and trucks with different coal qualities can unload coal at the same time. After unloading coal, the truck passes through the empty truck weighing device in the empty and loaded truck weighing system to measure the weight, and then leaves the plant or goes to the truck quantitative loading system for loading coal for external transportation. At the same time, the empty vehicle information and empty vehicle weight are uploaded to the central control system in real time, and the actual coal transport weight of each vehicle is automatically calculated. When the intelligent sensing system of the vehicle unloading coal bunker material level detects that the coal pile height in a second independent coal storage bunker reaches the set height, the central control system starts the bunker coal feeder set under the bunker, and transports the coal to the second coal distribution belt conveyor through the vehicle unloading coal bunker return coal belt conveyor and the unloading chute. Through the joint action of the second coal distribution belt conveyor unloading facility positioning control system, the coal yard boundary and coal pile height intelligent sensing system, and the coal yard position positioning display system, the second unloading facility is moved to the corresponding independent yard position in the coal yard, and the coal is unloaded into the corresponding independent yard; 3) When the train is loaded for transport, the intelligent identification and positioning system of the coal-loading train vehicle is used to guide the train to the appropriate position directly below the train quantitative loading system, and the vehicle information is uploaded to the central control system. The intelligent coal blending system determines the blending ratio of coal of different qualities according to the customer's requirements for coal quality parameters, and controls the coal feeder under the independent stockpile of the corresponding coal quality in the coal yard to output different amounts of coal through the positioning control system of the coal feeder under the coal yard. The coal is transferred to the train quantitative loading system through the first return coal belt conveyor and the first belt conveyor, and the train quantitative The loading system loads coal into the carriage until the entire train is full. During this process, coal of different qualities is mixed during transportation on the first coal return belt conveyor and the second belt conveyor. The first belt online coal quality detection system feeds back the mixed coal quality to the intelligent coal blending system in real time and compares it with the customer's coal quality parameter requirements. If there is a deviation, the intelligent coal blending system automatically adjusts the coal output of the coal feeder until the customer's coal quality parameters are met. The central control system saves the vehicle information, coal quality, and coal loading quantity, prints it out, and hands it over to the train driver; 4) When the coal-loaded truck is transported out of the plant, the empty truck is guided by the intelligent identification and positioning system for coal-loaded outbound trucks to drive to the appropriate position directly below the truck metering and loading system, and the vehicle information is uploaded to the central control system. According to the customer's requirements for coal quality parameters, the intelligent coal blending system determines the blending ratio of coals with different qualities, and then controls the coal feeders under the independent storage yards corresponding to the coal qualities in the coal storage yard to output different coal quantities through the positioning control system of the coal feeder under the coal storage yard. The coal is transported to the truck metering and loading system through the second coal return belt conveyor and the second belt conveyor, and the coal is loaded into the truck through the truck metering and loading system. During this process, coals with different qualities are blended during the transportation on the second coal return belt conveyor and the second belt conveyor. The on-line coal quality detection system of the second belt real-time feeds back the coal quality situation after blending to the intelligent coal blending system, and compares it with the customer's requirements for coal quality parameters. If there is a deviation, the intelligent coal blending system automatically adjusts the coal output of the coal feeder until the coal quality parameters required by the customer are met. The central control system saves and prints the vehicle information, coal quality situation, and coal loading quantity and hands them over to the truck driver.

[0025] In the embodiment of the present application, a coal intelligent storage, distribution, loading and unloading method with cross-operation is also proposed. Based on the above storage, distribution, loading and unloading system, it includes the following steps: 1) During the production process, when a coal train arrives, after the coal train enters the factory area, it passes through the coal train vehicle intelligent identification and positioning system 411 and the train coal online detection system 421, and uploads the vehicle information and coal quality to the central control system 46 in real time. The train carriage is transported to the train coal unloading bunker 113 by the train shunting facility 111. According to the prompt of the train coal unloading bunker position positioning display system 431, the train unloading facility 112 unloads the coal into the first independent coal storage bunker corresponding to the train coal unloading bunker 113. When the train coal unloading bunker material level intelligent sensing system 432 detects that the coal stacking height of a certain first independent coal bunker reaches the set height, the central control system 46 controls the impeller coal feeder 114 to move through the impeller coal feeder positioning control system 441 under the train coal unloading bunker To the corresponding first independent coal storage bin, the coal is transferred to the first coal distribution belt conveyor 21 together with the train unloading bin coal return belt conveyor and unloading chute 115, the transfer belt conveyor and unloading chute 116. Through the joint action of the first coal distribution belt conveyor unloading facility positioning control system 451, the yard boundary and coal pile height intelligent perception system 453, and the coal yard position positioning display system 454, the first unloading facility 211 is moved to the corresponding independent yard position in the coal yard 23, and the coal is unloaded into the corresponding yard, so that coal of different coal qualities in a train is unloaded into different first independent coal storage bins, and the cycle is repeated. After the train has unloaded all the coal, the empty car leaves the factory area or drives to the train quantitative loading system 312 to load coal for transportation.

[0026] 2) Similarly, when coal is delivered by trucks, after the coal-carrying trucks enter the plant area, they respectively upload vehicle information, heavy vehicle weight, and coal quality information to the central control system 46 in real time through the intelligent identification and positioning system 412 for coal-carrying trucks, the heavy vehicle weighing device in the truck empty and heavy vehicle weighing system 415, and the on-line coal quality detection system 422 for coal delivered by trucks. Then, they drive in front of the truck coal unloading bin 121 and unload the coal into the corresponding second independent coal storage bin according to the prompt of the truck coal unloading bin position positioning and display system 433, so as to realize unloading coal of different coal qualities into different second independent coal storage bins. Moreover, coal delivered by trucks of different coal qualities can be unloaded simultaneously. After unloading, the trucks leave the plant area after being weighed by the empty vehicle weighing device in the truck empty and heavy vehicle weighing system 415 or go to the truck quantitative loading system 322 for coal loading and outward transportation. At the same time, the empty vehicle information and empty vehicle weight are uploaded to the central control system 46 in real time, and the actual coal transportation weight of each truck is automatically calculated. When the intelligent perception system 434 for the material level of the truck coal unloading bin monitors that the coal stacking height in a certain second independent coal storage bin reaches the set height, the central control system 46 starts the coal feeder 122 under the bin, and transports the coal to the second coal distribution belt conveyor 22 through the return belt conveyor and discharge chute 123 under the truck coal unloading bin.

[0027] 3) When loading coal onto trains for outward transportation, the intelligent identification and positioning system 413 for the trains loading coal for outward transportation guides the train to drive to a suitable position directly below the train quantitative loading system 312 and uploads the vehicle information to the central control system 46. After determining the mixing ratio of coal of different coal qualities according to the customer's requirements for coal quality parameters, the intelligent coal blending system 457 controls the coal feeder 25 under the corresponding independent coal yard for the coal quality in the coal yard 23 to output different coal feeding amounts through the positioning control system 443 for the coal feeder under the coal yard. The coal is transported to the train quantitative loading system 312 through the first return belt conveyor 27 and the first belt conveyor 311. The train quantitative loading system 312 loads the coal into the carriage until the whole train is full. During this process, coal of different coal qualities is mixed during the transportation on the first return belt conveyor 27 and the first belt conveyor 311. The on-line coal quality detection system 455 for the first belt conveyor feeds back the coal quality situation after mixing to the intelligent coal blending system 457 in real time and compares it with the customer's requirements for coal quality parameters. If there is a deviation, the intelligent coal blending system 457 automatically adjusts the coal output of the coal feeder 25 until the customer's coal quality parameters are met. The central control system 46 saves and prints the vehicle information, coal quality situation, and coal loading amount and hands them over to the train driver.

[0028] 4) Similarly, when the coal-loaded truck is transported out of the plant, the empty truck is guided by the intelligent identification and positioning system 414 of the coal-loading and transporting trucks to drive to the appropriate position directly below the truck quantitative coal-loading system 322, and the vehicle information is uploaded to the central control system 46. After the intelligent coal blending system 457 determines the blending ratio of coals with different qualities according to the customer's requirements for coal quality parameters, it controls the coal feeders 25 under the independent stockpiles corresponding to the coals with different qualities in the coal yard 23 through the coal feeder positioning control system 443 under the coal yard to output different coal quantities. The coal is transported to the truck quantitative coal-loading system 322 through the second return coal belt conveyor 28 and the second belt conveyor 321, and the coal is loaded into the truck through the truck quantitative coal-loading system 322. During this process, the coals with different qualities are blended during the transportation on the second return coal belt conveyor 28 and the second belt conveyor 312. The second belt online coal quality detection system 456 timely feeds back the coal quality situation after blending to the intelligent coal blending system 457, and compares it with the customer's requirements for coal quality parameters. If there is a deviation, the intelligent coal blending system 456 automatically adjusts the coal output of the coal feeder 25 until the customer's coal quality parameters are met. The central control system 46 saves and prints the vehicle information, coal quality situation, and coal loading quantity and hands them over to the truck driver.
