Abstract:
At a single floor of a building, such as at the lobby, destination calls are entered via a destination call entry device touch pad such as a (12) so that overall system response can be optimized during up-peak service intervals. A maximum number of calls are assigned to each car in order of its priority, or advantageous situation with respect to loading the lobby passengers, and the dispatch interval for each car is individually adjusted. The calls may be assigned to a car prior to its arrival at the lobby, and call assignments are audibly and/or visually displayed by an indicator device (16).
Abstract:
A supervisory apparatus for elevators wherein cages are respectively caused to disperse and wait at predetermined floors during an inactive elevator operation during which a demand for the cages has decreased; the demand magnitudes of the cages in each of a predetermined number of time zones into which one day is divided, future demand magnitudes are estimated for each time zone on the basis of the measured values, and a suitable number of floors are allotted to each cage on the basis of the estimated demand magnitudes so that the respective cages may take charges of equal demand magnitudes during the inactive elevator operation. Further, the waiting floor of each cage is determined at that floor of the allotted floors at which an expected value of a period of time required for responding to a next occurring hall call becomes the smallest.
Abstract:
The disclosure relates to an elevator group supervisory control system in which bits of information, as to registered demands for service, position of the cars, and the degree of availability of the cars relative to the number of calls for service each is capable of answering without undue delay, are successively and repetitively scanned to control the respective movement of the cars.
Abstract:
Die Erfindung betrifft ein Verfahren zum Steuern einer Aufzugsanlage (100), welche mehrere Kabinen (112-120) aufweist, welche jeweils eine Anzahl von Stockwerken (130-135) anfahren können, wobei von außerhalb der Kabinen aus abgesetzte Rufe mittels einer Aufzugssteuerung (200) auf der Grundlage wenigstens eines Zuordnungskriteriums einer der Kabinen zugeordnet werden, wobei bei der Zuordnung die aktuelle Verkehrssituation der Aufzugsanlage (100) berücksichtigt wird, wobei eine Prognose einer zukünftigen Verkehrssituation der Aufzugsanlage (100) erstellt und bei der Zuordnung berücksichtigt wird, wobei die Prognose unter Berücksichtigung von Personeninformationen von Personen, die sich in einer vorbestimmten Umgebung der Aufzugsanlage oder eines Abschnitts der Aufzugsanlage (100) befinden oder sich in eine vorbestimmte Umgebung der Aufzugsanlage begeben oder sich aus einer vorbestimmten Umgebung der Aufzugsanlage entfernen, erstellt wird.
Abstract:
The invention relates to a method for handling destination calls in an elevator group comprising several elevators using destination call control, which method comprises an allocation procedure for situations where the calls can't be served by all elevators of the elevator group in one round trip, in which situation "n" open calls and "m" fixed calls are present, which fixed calls are already allocated but not served, in which allocation procedure a genetic algorithm (GA) is used in which the following succession of steps is performed: a) chromosomes comprising genes are formed, in which chromosomes: - n first genes comprise a correlation of each open call and a corresponding elevator, - n second genes comprise a correlation of each open call and the corresponding number of the round trip in which the open call will be served, and - m third genes comprise a correlation of each fixed call and the corresponding number of the round trip in which the fixed call will be served, b) for each chromosome round trips are calculated for each elevator of the elevator group according to collective control, c) the round trips of all elevators calculated in step b) are evaluated according to known optimization criteria, as e.g. passenger riding time, passenger waiting time, energy consumption, minimum number of round trips etc., d) chromosomes which are evaluated in step c) as sufficient are put forward to the forming of a new generation by per se known GA methods, as e.g. cross-breeding, mutation, etc., e) the steps b) to d) are repeated for each chromosome of each new generation of chromosomes until a stop criterion is achieved, f) the calls are served in collective control according to the best chromosome of the last generation, and g) the destinations of each elevator in its travelling direction in the current round trip according to the best chromosome are shown on a at least one common display shortly before its arrival at said landing. The invention solves the elevator dispatching problem under consideration of more than the current round trip of the elevators in the elevator group.
Abstract:
A method controls the distribution of free cars in an elevator system. First, the number of free cars in the elevator system are counted whenever this number changes. At the same time, the arrival/destination rates of passengers at each of the floor is determined. The rates are used to identify up-peak and down-peak traffic patterns. The floors of the building are then assigned to zones. The number of floors in each zone is determined according to the arrival rates, and the free cars are then parked in the zones so that the expected waiting time of the next arriving passenger is minimized.
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:
In an approach for determining an optimal path for an elevator, a processor receives information, wherein the information includes social media data associated with a user and calendar entries associated with the user, indicating one or more locations within a building. A processor analyzes the received information. A processor determines a location to send an elevator within the building to minimize movement of the elevator, based on the analyzed information. A processor causes the elevator to move to the location.
Abstract:
A method for controlling a lift installation having a plurality of cabins that can each stop at a number of floors may involve assigning calls placed outside the cabins to the cabins by way of a lift controller based on at least one assignment criterion. The method may involve considering a current traffic situation of the lift installation during the assignment. The method may further involve generating and considering a forecast of a future traffic situation of the lift installation during the assignment. The forecast may account for personal information of at least one of a person who is in a predetermined environment of the lift installation, a person who is in a section of the lift installation, a person who enters a predetermined environment of the lift installation, or a person who leaves a predetermined environment of the lift installation.”
