Abstract: In an elevator monitoring system, an operation monitoring apparatus receives operation condition data from a group supervisory control device so as to display operation conditions of elevators on a monitor. The operation monitoring apparatus and the interphone base device can telephone-communicate with each other. The operation monitoring apparatus detects that a passenger within a car of at least one of the elevators cannot perform an interphone communication based upon the operation condition data and information of communication conditions with respect to the interphone terminal devices, which are received from the interphone base device.

Abstract: Provided is an elevator control apparatus in a building in which a plurality of elevators are installed, the apparatus including: a congestion information detecting means (1B1) for detecting a landing area congestion state at each story floor and in each operating direction of all the elevators and generating congestion degree information about the entire building based on the landing area congestion state; a service state detecting means (1B2) for measuring waiting time for landing area call registrations at all the elevators, calculating an average value of the waiting time, and generating service state information about the entire building based on the average value; and a guidance display means (1B3) for displaying the congestion degree information and the service state information.

Abstract: An elevator group supervisory control system for an elevator system including indicators of positions of elevators, for a group supervisory control of elevators, in which a car reversal, which becomes a cause of irritation for passengers, is curbed. For a hall call registered at an elevator hall which is ahead of a final car call and within a floor range defined based on building or elevator conditions, an additional assignment is given to an elevator having shortest predicted arrival time, and which is not assigned to respond to the elevator hall call.

Abstract: Provided is an elevator group supervisory control system for an elevator system provided with indicators for a group supervisory control of a plurality of elevators, in which a car reversal, which becomes a cause of irritation for passengers, is curbed. For a hall call registered at an elevator hall which is ahead of a final car call and within a floor range defined bases on building or elevator conditions, an additional assignment is performed on an elevator whose predicted arrival time is the shortest, and which is not in charge of the elevator hall call.
