Abstract

This application relates to a bulk material unmanned loading control method, system and device based on multi-line laser radar. The present invention uses multi-line laser radar to collect three-dimensional point cloud data of the carriage, and identifies the size of the carriage, real-time moving position and real-time moving speed of the carriage , dynamically adjust the loading process, and realize unmanned automatic loading control. The present invention can adopt different control parameters for loading different compartment types, breaks through the technical bottleneck of intelligent loading, reduces loading cost, and improves loading efficiency. Solve the problem that the manual loading method in the prior art increases the labor cost and cannot effectively ensure the stability of the loading quality, and often occurs reciprocating loading or unbalanced loading of the loading, which makes the loading efficiency low.

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...
