Abstract:

A system and method for routing a carrier on a movable conveyance system having a multiplicity of switching stations and at least one carrier. Each carrier has an electronic readable tag coupled thereto, and each tag has a specific identifier that can be read. A reader is configured to read the electronic readable tag and to communicate the tag's identifier to a controller. The controller, in turn, is configured to control at least one switching station of the movable conveyance system based at least in part on the identifier.
