Abstract

The invention relates to a scheduling control method, a device and a system applied to multi-AGV cooperative operation. The method comprises the following steps: planning a current task walking path of a current AGV; detecting whether there is a conflict point on the current task walking path, and if there is a conflict point, jumping to a preemption judgment step; if there is no conflict point, planning a path under execution and jumping to a task execution step; finding out the farthest non-conflict point as a path under execution, jumping to the task execution step if detecting that the path under execution is not empty, judging whether a preemption condition is satisfied if detecting that the path under execution is empty, seizing a conflict point if the preemption condition is satisfied, and otherwise, jumping to the conflict point detection step after waiting for a preset time; and making the current AGV march forward to execute a task, judging whether the current task has a remaining path after the path under execution is finished, jumping to the conflict point detection step if the current task has a remaining path, and otherwise, switching the current AGV to an idle state. Non-blocking and collision-free operation of multiple AGVs can be realized, and the operation efficiency of AGVs can be ensured.

Description

technical field [0001] The invention relates to the technical field of automatic guided transport vehicles, in particular to a scheduling control method, device and system applied to multi-AGV cooperative operation. Background technique [0002] AGV (Automated Guided Vehicle) means "Automated Guided Vehicle". It is an important means of transportation for industrial 4.0 smart factories. The operating efficiency of AGV greatly affects the production efficiency of the entire unmanned chemical factory. As a means of transportation for the intelligent unmanned factory, AGV carries the task of workpiece transfer and connects the orderly and efficient operation of each production unit module in the intelligent factory. Therefore, when multiple AGVs work together, the traffic routes in the entire factory must run efficiently, orderly and safely. [0003] At present, if the path planned by the current AGV conflicts with the paths planned by other AGVs, that is, there are overlappi...
