Abstract

The invention relates to a bulk material unmanned loading control method, system and device based on a multi-line laser radar. The method comprises the steps: collecting three-dimensional point clouddata of a carriage through the multi-line laser radar; recognizing the size of the carriage, a real-time movement position of the carriage and a real-time movement speed; dynamically adjusting a loading process; and achieving unmanned automatic loading control. Different control parameters can be adopted for loading according to different carriage types, a technical bottleneck of loading intelligence is broken through, loading cost is reduced, and loading efficiency is improved. Problems that in the prior art, due to a fact that a manual loading mode is adopted, labor cost is increased, loading quality stability cannot be effectively guaranteed, conditions such as reciprocating loading or loading unbalance loading and the like often occur, and the loading efficiency is not high are solved.

Description

technical field [0001] The present application belongs to the technical field of unmanned loading, and in particular relates to a control method, system and device for unmanned loading of bulk materials based on multi-line laser radar. Background technique [0002] At present, most of the material loading systems in my country have a low degree of automation, and the loading process relies on manual control, including manual rough estimation of the position and moving speed of the compartment, manual visual inspection of the level of the compartment, and manual adjustment of the feeding amount at any time. However, the size and standard load of various receiving compartments are not fixed and uniform, and the inertia of the compartments changes greatly after receiving materials, resulting in poor handling of the vehicle, which makes the loading cloth effect not good, and the loading process is overly dependent on loading staff work experience. [0003] The manual loading me...
