Intelligent warehousing route planning system and method based on multiple AGVs

Abstract

The invention discloses an intelligent warehousing route planning method and system based on multiple AGVs. The method comprises the following steps: S100, defining a task distribution rule; dividing the priorities when the storage tasks are generated; S200, adjusting the dynamic priority; carrying out dynamic priority adjustment on the task of the AGV load in transportation; S300, planning an optimal path: dynamically and accurately calculating and locking a time window to reset a path so as to avoid conflicts, respectively carrying out coping strategy research on predictable vertical meeting conflicts and opposite meeting conflicts, and finally finding out a conflict-free shortest path; s400, predictively avoiding a conflict strategy; carrying out traffic rule making and unpredictable conflict detection and processing on traffic problems which may be encountered by a plurality of AGVs in the transportation process of a storage workshop. According to the system, the time cost of warehousing workshop tasks is reduced to the minimum, it is guaranteed that the path cost of the AGV is the minimum under the condition that vehicles are free of collision, and meanwhile the task scheduling efficiency and the vehicle scheduling efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of intelligent storage route planning, in particular to a multi-AGV-based intelligent storage route planning system and method. Background technique [0002] With the wide application of flexible manufacturing systems, people pay more and more attention to manufacturing costs, because the efficiency of machine tools and automation tools in manufacturing directly determines our manufacturing costs, including time costs, machinery costs, and labor costs. In flexible manufacturing, how to conduct reasonable AGV (Automated Guided Vehicle) task scheduling and planning, and improve the work efficiency of automated tools or machine tools is of great significance to the development of the manufacturing industry and the improvement of the core competitiveness of enterprises. [0003] With the rise of domestic e-commerce businesses led by JD Ali, the convenience of online shopping has gradually become popular. From sm...
