AGV Automatic Location Recognition and Unmanned Electromagnetic Induction Charging Method for Wireless Power Charging of AGV Robots

摘要

The present invention automatically recognizes the location of a wireless power transmission charger for unmanned wireless charging of an AGV (Auto Guided Vehicle) unmanned logistics transfer robot, and moves to a wireless power transmission transmitter (charger) to achieve the closest autonomous unmanned charging of the charger. It relates to an unmanned wireless electromagnetic inductive charging method that allows In general, the AGV robot repeatedly moves along a magnetic line in a fixed transfer section in a working environment in a factory, and receives driving electric energy from an internal secondary battery to perform a short-distance transfer operation. Due to the limitation of the allowed battery storage capacity, when the battery is discharged, it must be recharged, and when recharging, the operator performs the charge through an external wired charging cord. When charging the secondary battery, the user is exposed to the electrical risk of connecting the cord. The present invention enables the AGV robot to autonomously wirelessly charge by moving to the wireless power transmission transmitter through automatic location recognition in a situation where a battery low voltage warning or charging is required when the AGV robot is transported. Therefore, it recognizes the location of the charger and converges the amount of electromagnetic induced energy as PID control as PID control to calculate the position of electromagnetic induced energy with the highest optimal efficiency of wireless charging, and automatically position-recognition duning for unmanned wireless charging. A charging method was devised so that it could be carried out.
