Charging method of automatic guided vehicle (AGV), movable charging pile and charging system

Abstract

The invention provides a charging method of an automatic guided vehicle (AGV), a movable charging pile according to the charging method, and an AGV charging system. A moving path is independently planned through the movable charging pile, and the AGV is actively charged when the movable charging pile arrives at the AGV. Not only are AGV moving to a charging station for charging and working time occupation prevented, but also no interference and obstruction among different movable charging piles in a movement path are prevented. Furthermore high equipment utilization rate and in-time charging to the AGV are realized. The movable charging pile of the invention can move simultaneously with charged equipment for ensuring connection of charging interfaces, realizing continuous charging and ensuring continuous and non-stopped operation of the AGV. Furthermore, through scheduling by a background scheduling system, not only can charging timeliness be ensured, but also beforehand time arrangement for the movable charging pile can be realized, thereby ensuring most timely and most reasonable charging opportunity for the AGV in a busy charging task.

Description

technical field [0001] The invention relates to the field of automatic guided vehicles (AGV), in particular to a charging method, a charging pile and a charging system for an automatic guided vehicle (AGV). Background technique [0002] With the needs of national production, automatic guided vehicles (AGV) have gradually entered factories to replace traditional manual handling and have been quickly used. In a multi-system, in order to improve the utilization efficiency of each car, the focus is on optimizing the task scheduling algorithm of each car. In terms of charging, when the AGV needs to replenish power, it will automatically report and request charging. The ground control center will direct it to the designated charging area or station. The on-board charging connector is automatically connected to the ground charging system and charged. After the charging is completed, the AGV automatically disengages from the charging system and drives to the working area or standby...

AI Technical Summary

Problems solved by technology

[0005] 1. When one AGV is charging, other AGVs can only wait and release the charging pile when the charging AGV is fully charged

[0006] 2. When the AGV is charging, the AGV needs to leave the existing station, and the related work is stagnant

[0007] 3. During the charging process of AGV, the first-come-first-come method is adopted, which cannot guarantee the priority charging of AGVs at key stations.

[0008] 4. When each AGV is working, the charging pile is idle

In this way, the line is fixed, and the cost is high and inflexible

When there are multiple charging vehicles moving on the same track, it is very difficult to dispatch and avoid, and it also restricts the walking route of the AGV
