Abstract

The invention discloses a multi-laser AGV avoidance method. The method comprises steps of constructing an environment model, and setting stations and operation routes of laser AGVs; subdividing tasksand adding the subdivided tasks to a task attribute table of the laser AGVs; planning a route of a first unexecuted task in the task attribute table according to the path planning strategy, and updating t attributes of the AGV; in the driving process of the laser AGV, updating the information attribute of the laser AGV in real time,comparing the information attribute with task attributes of otherlaser AGVs, and determining whether the laser AGV needs to be driven to a temporary avoidance point or not; if so, changing a task attribute table of the AGV; if not, continuing to execute the tasks;if the AGV drives to a temporary avoidance point, determining whether a conflict domain is removed or not. The method is advantaged in that the situation that vehicles wait for each other or get stuckin opposite directions is avoided; the subtasks are redivided in real time according to the running state, the waiting time of the laser AGV is shortened, and the dynamic avoiding function is achieved.

Description

technical field [0001] The invention belongs to the technical field of automatic material transportation mechanical equipment control. More specifically, the present invention relates to a multi-laser AGV avoidance method. Background technique [0002] 1. Background introduction of related technology development: [0003] Automated Guided Vehicle (AGV) is a battery-powered wheeled robot that can move along a fixed or non-fixed route and transfer the device through the guiding device to realize material transportation. It is widely used as an efficient transportation equipment Industries such as factories with short order cycles and complex transportation routes, manufacturing workshops, and warehousing and logistics. [0004] With the rapid development of e-commerce and retail industries and the continuous improvement of the automation level in the factory production process, the demand for automatic guided vehicles (AGV) in the object handling and assembly environment is ...
