摘要:
In elevator equipment in which an elevator controller is connected by a common transmission line to an elevator cage and a plurality of apparatus installed at elevator stops on respective floors, signals are transmitted from the elevator controller to the elevator cage and the plurality of apparatus of elevator stops on respective floors. Information transmitted between the elevator controller and the cage as well as each apparatus at elevator stop on each floor is sorted into information which is different for each apparatus on each floor and the cage (unique information) and information which is the same for the plurality of apparatus at elevator stops on respective floors and the cage (common information), and the unique information is transmitted during a first period and the common information is transmitted during a second period, thereby reducing time required for transmission of information during one cycle.
