US 12,612,908 B2 · Pumping control method and apparatus, material distribution method and apparatus as well as distribution device

Abstract

The invention relates to the field of engineering machinery, and discloses a pumping control method and apparatus, a material distribution method and apparatus as well as a distribution device. The pumping control method includes: calculating an initialized pumping speed; controlling a distribution device to pump at the initialized pumping speed; and dynamically adjusting the pumping speed of the distribution device in real time according to a completed real-time distribution volume and real-time distribution time during the pumping of the distribution device until the real-time distribution volume is a desired distribution volume. Therefore, the accuracy of a final distribution volume is improved. The distribution method includes: controlling a distribution device to perform distribution at a to-be-distributed location in a preset distribution area; and after distribution at the to-be-distributed location is completed, determining a next to-be-distributed location in the preset distribution area and performing distribution at the next to-be-distributed location until distribution at each to-be-distributed location in the preset distribution area is completed. Therefore, automatic distribution is achieved.
