METHOD AND SYSTEM FOR CONTROLLING THE TRAFFIC FLOW OF AUTOMATED GUIDED VEHICLES AT INTERSECTION AND TRAFFIC CONTROLLER THEREFOR

摘要

An embodiment of the present invention relates to a method to control the traffic flow of an automated guiding vehicle at a crossroads, capable of controlling traffic by using at least two traffic controllers including a unique wireless communicable area to prevent crossroads on a driving route of an automated guiding vehicle to be overlapped and individually controlling traffic of automated guiding vehicles entering the crossroads in the wireless communicable area. The method includes: a first step in which an automated guiding vehicle transmits a request for an entry permission to a traffic controller controlling traffic of a specific crossroads before entering the crossroads; a second step in which the traffic controller receiving the request prioritizes the automated guiding vehicle transmitting the request if there is an automated guiding vehicle going through the crossroads or otherwise transmits the entry permission to the automated guiding vehicle if there is not an automated guiding vehicle going through the crossroads; and a third step in which the automated guiding vehicle transmits a passing completion message to the traffic controller right after passing the crossroads.
