A battery changing method and a battery changing system of an automatic guiding transport vehicle

Abstract

The invention discloses a battery changing method and a battery changing system of an automatic guiding transport vehicle. The method comprises the following steps: monitoring the current electric quantity of the automatic guiding conveyor; Acquiring a task state of the autopilot vehicle when a current electric quantity of the autopilot vehicle is lower than a first preset threshold value; obtaining the battery information list of the substation and the dynamic time matrix of the automatic guided vehicle to each substation When the task state is no task. According to the dynamic time matrix and the battery information list of the substation, the load of the substation nearest to the AGV is obtained. When the load condition of the substation nearest to the automatic guidance vehicle is notfull load, the substation is selected to replace the battery of the automatic guidance vehicle. The automatic guiding conveyor of the invention can realize power staggered at an appropriate time, stopreceiving new tasks when the electric quantity is too low, and preferentially carry out power replacement, thereby improving the efficiency of battery replacement and ensuring the normal operation ofthe automatic guiding conveyor.

Description

technical field [0001] The invention relates to the field of automatic guided transport vehicle charging, in particular to a battery replacement method and system for automatic guided transport vehicles. Background technique [0002] AGV is the abbreviation of Automated Guided Vehicle, which means "automatically guided transport vehicle", which means that it is equipped with automatic guidance devices such as electromagnetic or optical, which can drive along the prescribed guiding path, and has safety protection and various transfer functions. transport vehicle. [0003] The automated terminal will use AGVs during the loading and unloading of containers. The AGVs run on the installed batteries. It is necessary to charge the AGVs or replace the batteries regularly to ensure the normal operation of the AGVs. When the existing AGV needs to replace the battery, it directly finds a nearest replacement station to replace the battery according to the static time matrix (that is, t...

AI Technical Summary

Problems solved by technology

[0004] The static time matrix refers to the time required from the initial position of the AGV to each switching station, and the position of the AGV changes during the scheduling process. Therefore, the time required for the AGV to reach each switching station and the time required in the static time matrix Therefore, the accuracy of the nearest battery replacement station found directly based on the static time matrix is ​​low, and the battery replacement time is prolonged
