Traveling vehicle system and communication method in the traveling vehicle system

摘要

A system server and access points are connected through a LAN preferably on the ground. A control cycle is divided into an instruction time zone to provide instructions from the access points to traveling vehicles, and a report time zone to provide reports from the traveling vehicles to the access points. The access points transmit target positions in the instruction time zone, and the traveling vehicles report positions in the report time zone. The system server determines target positions based on the reported positions.
