AGV scheduling method and system for automatic container terminal

Abstract

The invention discloses an AGV scheduling method and system for an automatic container terminal. The method includes through acquiring the coordinates of each AGV in an idle state and the coordinatesof an idle interaction lane used for interaction with the AGVs of each quay crane executing unloading tasks, calculating the traveling time of each AGV in the idle state of moving to each idle interaction lane, matching the AGV in the idle state having the shortest traveling time for each idle interaction lane, and controlling the AGVs in the idle state to move the matched idle interaction lanes to carry the unloading tasks, wherein the AGVs in the idle state includes AGVs complete conveying tasks for quay cranes and disposed below the quay cranes carrying out the loading tasks. The method provided by the invention solves problems of long empty driving time and low utilization rate of the AGVs in the prior art, shortens the AGV empty driving time effectively, improves the AGV utilization rate, reduces energy consumption, reduces equipment loss and reduces operation cost.

Description

technical field [0001] The invention belongs to the technical field of automatic wharf scheduling, and in particular relates to an automatic container wharf AGV scheduling method and system. Background technique [0002] At present, in the AGV task scheduling method adopted by the automated container terminal, the task cycle is based on starting from the buffer zone, interacting with the quay bridge, and then returning to the buffer zone. This task scheduling algorithm makes AGV have half of the time in each cycle. The time is empty, especially during the loading process. After the AGV has finished delivering the boxes, it needs to drive out of the quay crane interaction lane and go to the buffer zone to wait for the next task. If the next task is the unloading task of another quay crane, Then it is necessary to drive empty into the quay bridge interactive lane, and the process of these two sections of empty driving has caused a lot of waste of resources, resulting in a low ...
