US 5,042,620 A · Elevator control system

Abstract

A control system for an elevator has a plurality of elevator information generation devices each of which has an information output unit which outputs elevator information to an elevator controller and also to at least one display controller which generates one or more on elevator displays. There are a plurality of display controllers, these are preferably connected to the information output units by a common transmission path. There may be a plurality of elevator controllers, when there are a plurality of elevator cabs, and those elevator controllers may all be connected to the common transmission path. There is then a supervisor controller for controlling the elevator controllers.

Dependent claims

An elevator control system with at least one elevator cab capable of serving plural floors, comprising:

a common transmission path;
an operation signal control device including at least one elevator operation controller, corresponding to the at least one cab and coupled to the common transmission path, for generating elevator control signals for controlling the service operation of the at least one cab and for transmitting the generated control signals to the common transmission path, in which said one elevator operation controller has means for managing the use of the common transmission path;
and
an elevator information control device including at least one information controller, connected to the common transmission path, and responsive to signals present on the common transmission path, for generating various service information to be given to users waiting for service of the at least one cab at the respective floors on said basis of the signals.

An elevator control system with plural elevator cabs each capable of serving plural floors, comprising;

a common transmission path;
an operation signal control device including a plurality of elevator operation controllers, each corresponding to a respective one of the cabs and being coupled to the common transmission path, each of said elevator operation controllers including means for generating elevator control signals for controlling the service operation of a corresponding cab and for transmitting the generated signals to the common transmission path, and at least one of said elevator operation controllers having means for managing the use of the common transmission path;
and
an elevator information control device including at least one, but less than the number of the elevator operation controllers, information controller, connected to the common transmission path, responsive to signals present on the common transmission path for generating various service information to be given to users waiting for service of the cabs at the respective floors on the basis of said signals.
