The train unloads all the coal, and the empty train drives away from the factory area or drives to the train quantitative loading system 312 to load coal for external transportation.

[0038] 2) Similarly, when the coal comes, the coal truck enters the factory area, and after passing through the coal truck vehicle intelligent recognition positioning system 412, the heavy vehicle weighing device in the automobile empty and heavy vehicle weighing system 415, the coal quality online detection system 422 of the coal truck, the vehicle information, the heavy vehicle weight and the coal quality are uploaded to the central control system 46 in real time, and then the coal is unloaded into the corresponding second independent coal storage bin before the automobile coal unloading bin 121, and the coal of different coal qualities is unloaded into different second independent coal storage bins, and the coal of different coal qualities can be unloaded at the same time.
