AGV charging management method, storage device and transport system

Abstract

The invention provides an AGV charging management method. The method includes the following steps that a charging threshold value a, a target electric quantity value b and a lowest electric quantity threshold value c are set; a total real-time electric quantity value e of AGVs in a transport system is monitored; an expected number g of to-be-charged AGVs in the transport system is calculated; theg AGVs are selected as the to-be-charged AGVs, whether the AGVs marked with execution of charging tasks exist in the expected number g of the to-be-charged AGVs or not is judged, according to the charging threshold value a and the lowest electric quantity threshold value c, the precedence levels of the to-be-charged AGVs are judged, and the to-be-charged AGVs are sequentially moved to operating charging piles to be charged according to the precedence levels; and an operation in a new round is started after one to-be-charged AGV is charged. The provided transport system applies the above AGV charging management method. By the adoption of the AGV charging management method, the charging precedence levels of the AGVs can be arranged quickly; and the transport system can assess the total electric quantity of the AGVs in the transport system and then execute charging management, so that AGV charging management decision making time is shortened.

Description

technical field [0001] The invention relates to the field of AGV charging management methods, in particular to the AGV charging management method, storage device and transportation system. Background technique [0002] With the development of industrial technology, more and more automation equipment is used in various production environments such as factories, warehouses and logistics, and AGV devices are more common automation equipment in the above-mentioned production environments. Under the circumstances, it can work around the clock, and in order to ensure the normal operation of the AGV device, it is necessary to charge the AGV device in due course. [0003] The common AGV device charging management method is that the central control system monitors all the AGV devices in the transportation system in real time. When it detects that the power of an AGV device is lower than the set reference power, the central control system uses the dispatching device to find idle time ...

AI Technical Summary

Problems solved by technology

However, this charging management method has the following problems: when the power of multiple AGV devices is lower than the set reference power, multiple AGV devices will simultaneously move to an idle charging station for charging, but due to the insufficient number of idle charging stations, resulting in Some AGV devices wait too long for charging, and the AGV devices automatically shut down due to low power. At this time, manual intervention is required to move the AGV devices to the charging station for charging and restarting, which affects the working efficiency of the entire transportation system.
