Abstract

A travel system includes a travelling carriage that travels on a predetermined track, access points including first APs that wirelessly communicate with the travelling carriage and second APs that wirelessly communicate with the travelling carriage in a communication slot different from a communication slot of the first APs, and a controller that, via any one of the access points, receives from the travelling carriage position information indicating the current position of the travelling carriage, and transmits to the traveling carriage a travel instruction to control travel of the travelling carriage. The travelling carriage includes a wireless interface that wirelessly communicates with one of the first APs, and wirelessly communicates with one of the second APs when wireless communication with the one of the first APs is not possible.
