Abstract:
An elevator control of an elevator installation with at least two elevator cars that move independently of one another in a common elevator shaft has a control device for fixing a first common direction of travel of the at least two elevator cars and for reversing this first direction of travel on the basis of at least one internal destination floor selection and/or an external conveying request and/or a destination call only when all of the internal destination floor selections and/or all of the external conveying requests and/or all of the destination calls in the first direction of travel have been processed.
Abstract:
An elevator group supervisory control apparatus is obtained which can achieve efficient group supervisory control while preventing or reducing the possibility of collision and the safe stopping of an upper car and a lower car in one and the same shaft as much as possible. The apparatus includes a hall destination floor registration device 4 that is installed in each hall and has a destination floor registration function and a function of providing a predictive indication of a response car for each destination floor, a zone setting section 12 that sets priority zones and a common zone for each of upper and lower cars, an entry determination section 13 that determines whether the upper and lower cars can come into the common zone, a safe waiting section 14 that makes the cars 20 wait safely in accordance with the determination result of the entry determination section 13, a shunting section 15 that makes each car 20 move to a shunting floor as required at the instant when each car finished its service, a confinement time prediction section 16 that predicts a confinement time due to safe waiting when each car is assigned to a destination call generated in a hall, an evaluation value calculation section 17 that evaluates a waiting time, the confinement time, etc., upon assignment of each car, and an assignment section 18 that determines a final assigned car on the basis of the calculation result of the evaluation value calculation section 17.
Abstract:
The invention relates to a method for controlling an elevator installation with at least one shaft and a number of cars, it being possible to make at least two cars travel separately up and down along a common traveling path and a passenger being able to enter a destination call by means of an input unit disposed outside the shaft and the destination call being allocated to a car in dependence on an allocation assessment. To develop the method in such a way that the transporting capacity can be increased, with the cars which can be made to travel along a common traveling path hindering one another as little as possible, it is proposed according to the invention that, in the case of allocation of the destination call to one of the cars which can be made to travel along the common traveling path, the portion of the traveling path required for serving the destination call is assigned to this car and blocked for the time of the assignment for the other cars. Furthermore, an elevator installation for carrying out the method is proposed.
Abstract:
Die vorliegende Erfindung betrifft ein Verfahren zum Betreiben eines Aufzugsystems (1) mit einem Schachtsystem (2) und einer Mehrzahl von Aufzugkabinen (3), welche in einem Umlaufbetrieb separat voneinander zwischen Stockwerken (4) verfahren werden, derart, dass die Aufzugkabinen (3) in einem ersten Schacht (5) aufwärts verfahren werden und in einem zweiten Schacht (6) abwärts verfahren werden. Dabei wird wenigstens eine der Anzahl der Aufzugkabinen (3) entsprechende Anzahl von Schachtpositionen (7) definiert, welche von den Aufzugkabinen (3) jeweils angefahren werden können, wobei bezüglich dieser definierten Schachtpositionen (7) eine Synchronisierung des Verfahrens der Aufzugkabinen (3) durchgeführt wird. Des Weiteren betrifft die vorliegende Erfindung ein Aufzugsystem (1) mit einem Schachtsystem (2), einer Mehrzahl von in dem Schachtsystem (2) verfahrbaren Aufzugkabinen (3) und einer Steuereinrichtung zum Betreiben des Aufzugsystems (1), wobei die Steuereinrichtung eingerichtet ist, das Aufzugsystem (1) gemäß einem erfindungsgemäßen Verfahren zu betreiben.
Abstract:
A method for operating an elevator system having a shaft system and elevator cars that are moved separately between floors in a circulation operation may involve moving the elevator cars upward in a first shaft and moving the elevator cars downward in a second shaft. A number of shaft positions that can be respectively adopted by the elevator cars and that correspond to the number of elevator cars is defined, and synchronization of movement of the elevator cars may be carried out with respect to these defined shaft positions. Further, each of the elevator cars may be moved according to a travel curve. To synchronize the movement of the elevator cars the travel curve for each elevator car may be adapted to account for positions of the elevator cars in the same shaft.
Abstract:
In an elevator system in which a plurality of cars are operated in a coupled or independent manner in a single hoistway, an elevator group-control device includes a front-car car-call detection unit detecting a car call of a front car with respect to its traveling direction out of the plurality of cars or for detecting a floor and a car that are assigned a destination floor of a registered destination floor call; and a rear-car assignment-candidate exclusion unit excluding, from assignment candidate cars, a rear car in the same hoistway as the front car assigned the car call when a landing call for the same direction as the traveling direction is registered at a floor registered by the car call detected by the front-car car-call detection unit.

Abstract:
The movement of a plurality of elevator cars (12, 14) in an elevator hoistway (16) is coordinated for situations in which the regions of the hoistway that are serviceable by the cars (12, 14) at any given time are configured to overlap. A car stop plan for each elevator car (12, 14) is generated that includes a sequence of stops for servicing demand assigned to the elevator car (12, 14). Operation of the elevator cars (12, 14) is then coordinated based on the car stop plans such that each elevator car (12, 14) services its assigned demand without interfering with the car stop plans of any other of the plurality of elevator cars (12, 14).
