Abstract
Abstract The system includes equipments necessary for demand registration and control organized hierarchically. The uppermost hierarchy level includes an operations control center and station equipment connected to the operations control center. The operations control center indicates the operation necessary at the next hierarchy level in accordance with the demand registered in the station equipment. The next hierarchy level includes one or more command and control centers. Each command and control center checks the commands of the operations control center and/or of the associated station equipment, giving special consideration to safety criteria, and passes on the commands to the last hierarchy level for execution. The last hierarchy level includes operation facilities, such as vehicles, which perform the requested transport tasks, continuously exchanging information with their associated command and control center.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
182 words
A system for the demand-dependent control of guided vehicles where the equipment necessary of demand registration and control are organized hierarchically comprising: an uppermost hierarchy level including an operations control center, and a plurality of station equipment each coupled to said operations control center by a two-way communication path, said operations control center initiating commands in accordance with destination demands at each of said plurality of station equipment; an intermediate hierarchy level including at least one commad and control center coupled to associated ones of said plurality of station equipment by a two-way communication path and coupled to said operations control center by a two-way communication path, said command and control center checks commands received from said operations control center and said associated ones of said plurality of station equipment giving special consideration to safety criteria; and a last hierarchy level including a plurality of vehicles coupled to said command and control center by a two-way communication way to perform the requested tasks in commands received from said command and control center and continuously exchanges information with said command and control center.
Claim 2
Independent Claim
182 words
A system for the demand-dependent control of guided vehicles where the equipment necessary of demand registration and control are organized hierarchically comprising: an uppermost hierarchy level including an operations control center, and a plurality of station equipment each coupled to said operations control center by a two-way communication path, said operations control center initiating commands in accordance with destination demands at each of said plurality of station equipment; an intermediate hierarchy level including at least one commad and control center coupled to associated ones of said plurality of station equipment by a two-way communication path and coupled to said operations control center by a two-way communication path, said command and control center checks commands received from said operations control center and said associated ones of said plurality of station equipment giving special consideration to safety criteria; and a last hierarchy level including a plurality of vehicles coupled to said command and control center by a two-way communication way to perform the requested tasks in commands received from said command and control center and continuously exchanges information with said command and control center.
Claim 3
Dependent Claim
