Abstract:
Die Erfindung geht aus von einer Aufzugssteuerung einer Aufzugsanlage (10; 10') mit zumindest zwei Aufzugskabinen (20, 22, 24, 26, 28, 30, 32, 34, 36; 26', 28', 30'), die dazu vorgesehen sind, unabhängig voneinander in einem gemeinsamen Fahrschacht (14, 16, 18; 16') verfahren zu werden, und mit einem Steuergerät (12; 12'). Es wird vorgeschlagen, dass das Steuergerät (12; 12') dazu vorgesehen ist, eine erste gemeinsame Fahrtrichtung (38, 40, 42; 40') der mindestens zwei Aufzugskabinen (20, 22, 24, 26, 28, 30, 32, 34, 36; 26', 28', 30') in dem gemeinsamen Fahrschacht (14, 16, 18; 16') festzulegen und aufgrund zumindest einer internen Zielstockwerkauswahl (46, 48, 50) und/oder einer äußeren Beförderungsanforderung (44) und/oder eines Zielrufs (58) diese erste Fahrtrichtung (38, 40, 42; 40') für die mindestens zwei Aufzugskabinen (20, 22, 24, 26, 28, 30, 32, 34, 36; 26', 28', 30') erst dann umzukehren, wenn alle internen Zielstockwerkauswahlen (46, 48, 50) und/oder alle äußeren Beförderungsanforderungen (44) und/oder alle Zielrufe (58) der Aufzugskabinen (20, 22, 24, 26, 28, 30, 32, 34, 36; 26', 28', 30') in der ersten Fahrtrichtung (38, 40, 42; 40') abgearbeitet sind.
Abstract:
A group controller for controlling elevator cars in a building having a plurality of floors includes a traffic and traffic rate estimator for providing fuzzy estimates of traffic and traffic rate; an open loop fuzzy logic controller for providing a control parameter in response to the fuzzy estimates of traffic and traffic rate; and an elevator dispatcher for controlling the operation of the elevator cars during single source traffic conditions in response to the control parameter.
Abstract:
An elevator group control device and an elevator group control method can eliminate congestion caused by stoppage, jam or deadlock in a vertical and horizontal movement type elevator system. The vertical and horizontal movement type elevator system controls running of a plurality of cages capable of vertically moving in a plurality of shafts and horizontally moving between the shafts. In the system, path data are stored for each of the cages, target floor data including target floors are produced on the basis of call data obtained correspondingly to the respective cages and platform call data obtained correspondingly to the respective floors, periods of time required for the cages to arrive at the target floor is predicted on the basis of the path data, target floor data, call data and cage data indicative of positions of the respective cages, and predetermined cages are allotted to predetermined platform calls on the basis of the predicted arrival time.
Abstract:
An elevator system includes a first elevator car (28) constructed and arranged to move in a first lane (30, 32, 34) and a first propulsion system (40) constructed and arranged to propel the first elevator. An electronic processor of the elevator system is configured to selectively control power delivered to the first propulsion system (40). The electronic processor includes a software-based power estimator configured to receive a first weight signal and a nm trajectory signal for calculating a power estimate and comparing the power estimate to a maximum power allowance. The electronic processor is configured to output an automated command signal if the power estimate exceeds the maximum power allowance.

Abstract:
To assign a car to a hall call such that cars A, B, C, D tend to be equally spaced apart and so that bunching of cars is avoided, the position of each car is predicted over a given period by estimating where it will arrive and leave each of its committed stops over that period for a given set of hall call/car call assignments, a bunching measure is calculated and a car to hall call assignment is made in response to the bunching measure.
