Method and apparatus for the group control of elevators with double cars

Abstract From the Canadian patent

In a group of elevators with double cars the assignment, of such double cars to floor calls takes place at scanner positions ~ in two procedural steps, according to two parameters: primarily by assignment of the individual cars of all double cars by logical decision according to a, criteria chain (KK), and subsidiarily by assignment of the double cars according to the minimal loss time of all involved passengers. The individual elevators each have a microcomputer system with a calculating device and are connected with each other by way of a comparator circuit to form a group control. The optimal individual cars are assigned for each elevator by floor in the associated individual car/call …
