Travelling vehicle system

摘要

A travelling vehicle system that allows a travelling vehicle to smoothly pass through a switching region where a state of a track is switched. The system includes a switching device which switches a state of a track in the switching region, and a host controller which manages a travelling vehicle. The switching device includes a detector which detects the state of the track in the switching region, and a report device which is arranged along the track from the switching region toward the upstream side of the track and reports switching information showing the state of the track. The host controller includes a permission issuing part which issues to the travelling vehicle controller a passage permission, and the travelling vehicle controller includes a travelling control part which determines whether or not to stop before the switching region based on the passage permission and the switching information.
