Background

When bulk cargoes are loaded, the weight of the loaded bulk cargoes needs to be controlled so as to reduce the possibility of overload of the vehicle and ensure the running safety of the vehicle.

In the related art, the control method for the loading weight of the vehicle is as follows: before loading the vehicle, the empty vehicle needs to travel to the wagon balance to weigh the weight of the empty vehicle; then, after the vehicle is loaded, the vehicle needs to travel again to the wagon balance to weigh the total weight of the loaded vehicle. By comparing the weights of the vehicles before and after loading, whether the vehicles are overloaded or not is judged. When the vehicle is overloaded, the vehicle drives down the wagon balance and unloads a part of bulk cargo; then driving up the wagon balance again to weigh again; the above steps are repeated until the bulk cargo carried by the vehicle is within a specified range, and the vehicle can go on the road.

When the related art is implemented, the vehicle needs to be weighed at least twice, and the occupied time is more, so that the loading efficiency of bulk cargo is lower, and the improvement is needed.
