ABSTRACT:
A carriage running control system includes a plurality of readable and writable memory media installed along a running track of carriages. Each carriage is capable of communicating information with the memory media. The running track includes special zones such as curved sections, branching sections, merging sections, and sections including stations. When a preceding carriage is present in one of such special zones, the memory medium disposed at the entry end of this zone supplies presence information to a succeeding carriage to prevent the latter from entering the zone. A detector is disposed at the exit end of each such zone for detecting departure of the carriages and resetting the memory medium at the entry end.
