Abstract:
System for controlling the elevators in an elevator system, which elevator system comprises a number of elevators (1A...1 H). The system comprises first sensor means (2, 2A...2H), which are arranged in the waiting area of each elevator (1A...1 H) on each floor (F, F1, F2, F3... Fn), which sensor means (2, 2A...2H) are fitted to give information about the presence and number of passengers waiting for an elevator at least in the waiting area in question; means for controlling the elevators, which means are fitted to receive information from the sensor means (2, 2A...2H) about the presence and number of passengers waiting for an elevator and to control the movement of the elevators of the elevator system utilizing the information received from the sensor means.
Abstract:
Die Erfindung betrifft ein Verfahren zur Zuteilung von Rufen einer Aufzugsanlage mit mindestens einem Aufzug und mindestens einer Kabine (1, 1') pro Aufzug. Von mindestens einem Passagier wird mindestens ein Ruf auf ein Zielstockwerk eingegeben. Eine Mehrzahl von Passagieren wird gemäss eingegebener Rufe von der Kabine (1, 1') in mindestens einer Fahrt von mindestens einem Eingabestockwerk auf mindestens ein Zielstockwerk verfahren. Für die eingegebenen Rufe der Fahrt wird mindestens eine Startzone (9, 9') mit einem oder mehreren Eingabestockwerken ermittelt. Für die eingegebenen Rufe der Fahrt wird mindestens eine Zielzone (10, 10') mit einem oder mehreren Zielstockwerken ermittelt. Falls mindestens eine Anzahl Halte in der Startzone (9, 9') und/oder in der Zielzone (10, 10') grösser Eins ist, wird diese Anzahl Halte reduziert.
Abstract:
Method for organizing the operation of elevator groups in a building having one or more sky lobbies (H) serving as an entrance floor for local elevator groups disposed above and below them and serving given floors, and as a terminal floor for at least one shuttle elevator group (G) transporting passengers from the entrance floor (I) of the building to a sky lobby (H), in which method congestion of traffic at the sky lobby (H) is prevented by using a group control system.
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; a closed loop fuzzy logic controller for providing a control parameter in response to the fuzzy estimates of traffic and traffic rate and in response to an elevator control system output variable; 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 system including a group controller for controlling the dispatching of elevator cars to the lobby. The group controller predicts lobby single source traffic for short periods. When the predicted traffic is below a certain limit, cars are assigned to a lobby hall call on demand after hall call registration. When the predicted traffic is above a certain limit, cars are assigned to the lobby hall call at intervals. Accordingly, car assignment is scheduled at those intervals. The traffic threshold at which the scheduled mode is activated and the traffic threshold at which it is deactivated is learned by the system. The schedule interval is varied based on predicted traffic and predicted round trip time of the cars. The number of cars assigned and sent to the lobby is varied based on predicted traffic. In order to avoid oscillations in selecting the service mode, proper delays are used to activate and deactivate the scheduled service.
Abstract:
A group controller for controlling elevator cars in a building having a plurality of floors includes an elevator dispatcher for controlling the operation of the elevator cars during single source traffic conditions, the elevator dispatcher having a contraint for limiting car assignments in response to the contraint; and an adaptive contraint generator for modifying a value of the contraint in response to an elevator control system output variable. In one embodiment, the group controller includes a traffic and traffic rate estimator for providing fuzzy estimates of traffic and traffic rate; a fuzzy logic controller for providing a control parameter in response to the fuzzy estimates of traffic and traffic rate, the control parameter having a contraint for limiting a value of the control parameter; and adaptive contraint generator for modifying a value of the contraint in response to an elevator control system output variable; and an elevator dispatcher for controlling the operation of the elevator cars during single source traffic conditions in response to the control parameter.
