Abstract

An elevator control system includes a car load measuring device for generating a car load signal representing the number of passengers in an elevator car and a floor load sensor for generating a signal representing the number of passengers waiting for an elevator at each floor. As the elevator car approaches the next floor at which it could stop, the floor load sensor generates its signal for that floor which is combined with the car load signal in an adder to generate a signal representing the total car load if the elevator car were to stop. The signal representing the total load is compared with a signal representing a maximum permissible car load and, if the maximum has not been exceeded, an enable signal is generated to one input of each of a plurality of logic circuits. The second input of each logic circuit is connected to a memory cell for a corresponding floor in a floor call memory and the third input of each logic circuit is connected to the corresponding floor in the floor selector device. Thus, when the signal representing the next floor at which the elevator car could stop corresponds to a stored floor call for that floor and the total potential load does not exceed the maximum permissible load, the corresponding logic circuit will generate a stop signal to cause the elevator to stop at the respective floor.

Description

Die Erfindung betrifft eine Einrichtung zur lastabhängigen Steuerung eines Aufzuges, mit einem Selektor, der jeweils dasjenige Stockwerk signalisiert, auf dem eine fahrende Aufzugskabine noch anhalten könnte, mit einer in der Aufzugskabine angeordneten Lastmesseinrichtung und mit einem Stockwerkrufspeicher, in welchem von der Aufzugskabine zu bedienende Stockwerkrufe gespeichert sind, wobei die Aufzugskabine in Abhängigkeit von der Last das nächste zu bedienende Stockwerk durchfährt oder dort anhält.The invention relates to a device for load-dependent control of an elevator, with a selector that signals the floor on which a moving elevator car could still stop, with a load measuring device arranged in the elevator car and with a floor call memory in which floor calls to be served by the elevator car are stored, the elevator car driving through the next floor to be operated depending on the load or stopping there.

Derartige Steuerungen weisen beispielsweise Lastmesseinrichtungen mit Vollastkontakten auf, die entsprechend den Verkehrsverhältnissen auf bestimmte feste Lastgrenzwerte einstellbar sind. So ist es üblich, bei schwachem Verkehr den Lastgrenzwert niedrig und bei starkem Verkehr hoch einzustellen, wodurch die Wartezeiten der Fahrgäste reduziert werden können.Controls of this type have, for example, load measuring devices with full-load contacts which can be set to specific fixed load limit values in accordance with the traffic conditions. It is common to set the load limit low in light traffic and high in heavy traffic, which can reduce the waiting times for passengers.

Bei Aufzügen mit Steuerungseinrichtungen für den Abwärtsspitzenverkehr, wie beispielsweise mit der DE-OS 1 803 648 bekannt geworden, werden der zu erwartenden Verkehrsdichte entsprechend hohe Lastgrenzwerte eingestellt. Jedem Aufzug ist zudem nur eine bestimmte kleine Anzahl Stockwerkrufe, z.B. drei, zugeordnet, wobei angenommen wird, dass auch beim dritten Halt alle wartenden Fahrgäste mitgenommen werden können und die Aufzugskabine annähernd voll ausgelastet ist. Wird der Lastgrenzwert beispielsweise schon beim zweiten Halt erreicht, so durchfährt die Aufzugskabine das dritte zugeordnete Stockwerk, wobei die Durchfahrlast dem fest eingestellten Lastgrenzwert entspricht. Können bei einem Halt wegen Erreichen des Lastgrenzwertes nicht alle wartenden Fahrgäste mitgenommen werden, so muss eine weitere Aufzugskabine für das gleiche Stockwerk eingesetzt werden, wodurch mit Bezug auf das gesamte Aufzugssystem grössere Zeitverluste entstehen.In elevators with control devices for downward peak traffic, as has become known, for example, from DE-OS 1 803 648, high load limit values are set in accordance with the expected traffic density. Each elevator is also only a certain small number of floor calls, e.g. three, assigned, whereby it is assumed that even at the third stop, all waiting passengers can be taken along and the elevator car is almost fully utilized. If, for example, the load limit value is already reached at the second stop, the elevator car travels through the third assigned floor, the drive-through load corresponding to the fixed load limit value. If it is not possible to take all waiting passengers on a stop due to the load limit being reached, then an additional elevator car must be used for the same floor, which means that there is a greater loss of time in relation to the entire elevator system.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung der eingangs genannten Art zu schaffen, bei der die Durchfahrlast derart steuerbar ist, dass für ein bestimmtes zu bedienendes Stockwerk nur eine Aufzugskabine eingesetzt werden muss.The invention has for its object to provide a device of the type mentioned, in which the drive-through load can be controlled such that only one elevator car has to be used for a particular floor to be operated.

Diese Aufgabe wird durch die im Patentanspruch gekennzeichnete Erfindung gelöst. Hierbei ist ein Addierer vorgesehen, der aus der Anzahl der in der Aufzugskabine befindlichen Fahrgäste und der Anzahl der auf dem nächsten zu bedienenden Stockwerk wartenden Fahrgäste eine Summe bildet. In einem Komparator wird diese Summe mit einer einem Lastgrenzwert entsprechenden Anzahl Fahrgäste verglichen, wobei bei Uberschreiten des Lastgrenzwertes die Aufzugskabine durchfährt und die Durchfahrlast der Anzahl der in der Aufzugskabine befindlichen Personen entspricht. Bei Gleichheit oder Unterschreiten des Lastgrenzwertes hält die Aufzugskabine auf dem betreffenden Stockwerk an.This object is achieved by the invention characterized in the claim. Here, an adder is provided, which is the number of be in the elevator car sensitive passengers and the number of passengers waiting on the next floor to be served form a sum. This sum is compared in a comparator with a number of passengers corresponding to a load limit value, the elevator car driving through when the load limit value is exceeded and the drive-through load corresponding to the number of people in the elevator car. If the load limit equals or falls below the limit, the elevator car stops on the relevant floor.

Die mit der Erfindung erzielten Vorteile sind darin zu sehen, dass insbesondere bei hoher Verkehrsdichte in Abwärtsrichtung die im vorstehend geschilderten Stand der Technik erwähnten Zeitverluste vermieden werden. Da bei der Durchfahrentscheidung die zu erwartende Zusteigerzahl in Rechnung gestellt wird, finden entweder alle wartenden Fahrgäste bei einem Halt Platz oder die Aufzugskabine fährt durch, wobei der nicht bediente Ruf einer anderen Aufzugskabine zugeteilt wird. Auf diese Weise wird erreicht, dass immer nur eine Aufzugskabine für ein bestimmtes zu bedienendes Stockwerk eingesetzt wird.The advantages achieved by the invention can be seen in the fact that, particularly in the case of high traffic density in the downward direction, the time losses mentioned in the prior art described above are avoided. Since the anticipated number of boarding passengers is taken into account in the drive-through decision, either all waiting passengers find a stop at one stop or the elevator car drives through, the unattended call being assigned to another elevator car. In this way it is achieved that only one elevator car is used for a particular floor to be operated.

Im folgenden wird die Erfindung anhand eines auf der Zeichnung dargestellten Ausführungsbeispieles näher erläutert. Es zeigen:

  • Fig. 1 eine schematische Darstellung der erfindungsgemässen Einrichtung, mit einer ersten Art der Ermittlung von auf einem Stockwerk wartenden Fahrgästen und
  • Fig. 2 eine schematische Darstellung der Einrichtung, mit einer zweiten Art der Ermittlung von auf einem Stockwerk wartenden Fahrgästen.
The invention is explained in more detail below with reference to an exemplary embodiment shown in the drawing. Show it:
  • Fig. 1 is a schematic representation of the device according to the invention, with a first type of determination of passengers waiting on a floor and
  • Fig. 2 is a schematic representation of the device, with a second type of determination of passengers waiting on a floor.

In der Fig. 1 ist mit 1 ein beispielsweise vier Stockwerke E9 - E12 umfassender Teil eines Aufzugsschachtes einer aus mehreren Aufzügen bestehenden Aufzugsgruppe bezeichnet, in welchem eine über ein Förderseil 2 antreibbare Aufzugskabine 3 geführt ist. Die Aufzugskabine 3 weist eine Lastmesseinrichtung 4 auf, mittels welcher die Anzahl L der eingestiegenen Fahrgäste festgestellt werden kann. Mit 5 sind Stockwerkrufknöpfe für Abwärtsrufe bezeichnet, die mit den Eingängen von Speicherzellen eines Stockwerkrufspeichers 6 verbunden sind. Auf den Stockwerken sind Sensoren 7 angeordnet, mittels welchen die Anzahl W der auf dem jeweils betreffenden Stockwerk wartenden Fahrgäste ermittelt werden kann. Ein Addierer 8 ist eingangsseitig mit einem Ausgang der Sensoren 7 und der Lastmesseinrichtung 4 verbunden. Ausgangsseitig steht der Addierer 8 mit einem Komparator 9 in Verbindung, dem über einen weiteren Eingang ein einer maximal zulässigen Anzahl A Fahrgäste entsprechender Lastgrenzwert zuführbar ist. Mit 10 ist ein Selektor bezeichnet, der jeweils dasjenige Stockwerk signalisiert, auf dem die fahrende Aufzugskabine 3 noch anhalten könnte. Den Stockwerken zugeordnete Ausgänge des Selektors 10 sind mit Eingängen der betreffenden Sensoren 7 verbunden, die immer dann die ermittelte Anzahl W der wartenden Fahrgäste freigeben, wenn das vom Selektor erzeugte Signal eintrifft. Den Speicherzellen des Stockwerkrufspeichers 6 sind drei Eingänge aufweisende logische Schaltkreise 11 in Form von beispielsweise UND-Gliedern zugeordnet, wobei die ersten Eingänge mit dem Ausgang des Komparators 9, die zweiten Eingänge mit den Ausgängen der jeweils zugeordneten Speicherzellen und die dritten Eingänge mit den Ausgängen des Selektors 10 verbunden sind. Die Ausgänge der logischen Schaltkreise 11 stehen mit einer nicht weiter dargestellten und beschriebenen Fahrsteuerung des Aufzuges in Verbindung.In FIG. 1, 1 denotes a part of an elevator shaft of an elevator group consisting of several elevators, for example comprising four floors E9-E12, in which an elevator car 3 which can be driven by a conveyor cable 2 is guided. The elevator car 3 has a load measuring device 4, by means of which the number L of boarded passengers can be determined. 5 with floor call buttons for downward calls, which are connected to the inputs of memory cells of a floor call memory 6. Sensors 7 are arranged on the floors, by means of which the number W of passengers waiting on the respective floor can be determined. An adder 8 is connected on the input side to an output of the sensors 7 and the load measuring device 4. On the output side, the adder 8 is connected to a comparator 9, to which a load limit value corresponding to a maximum permissible number of A passengers can be fed via a further input. With 10 is one Denoted selector, which signals the floor in each case on which the moving elevator car 3 could still stop. Outputs of the selector 10 assigned to the floors are connected to inputs of the sensors 7 in question, which always release the determined number W of the waiting passengers when the signal generated by the selector arrives. The memory cells of the storey call memory 6 are assigned three logic circuits 11 having inputs, for example in the form of AND gates, the first inputs with the output of the comparator 9, the second inputs with the outputs of the respectively assigned memory cells and the third inputs with the outputs of the Selector 10 are connected. The outputs of the logic circuits 11 are connected to a travel control of the elevator, which is not shown and described.

In der Fig. 2 ist anstelle der auf den Stockwerken angeordneten Sensoren 7 der Fig. 1 ein in ähnlicher Form mit dem EP 0 032 213 bekannt gewordener Lastspeicher 12 vorgesehen, der mit der Lastmesseinrichtung 4 und dem Addierer 8 verbunden ist. Im Lastspeicher 12 werden die bei jedem Zusteigehalt ermittelten Lastdifferenzen gespeichert und aus den Lastdifferenzen und der Anzahl Zusteigehalte ein Mittelwert gebildet, der dem Addierer 8 als wahrscheinliche Anzahl W der auf dem nächsten zu bedienenden Stockwerk wartenden Fahrgäste zugeführt wird.In FIG. 2, instead of the sensors 7 of FIG. 1 arranged on the floors, a load store 12, which has become known in a similar manner to EP 0 032 213 and is connected to the load measuring device 4 and the adder 8, is provided. The load differences determined at each boarding level are stored in the load memory 12, and an average value is formed from the load differences and the number of boarding levels, which is fed to the adder 8 as the probable number W of the passengers waiting on the next floor to be served.

Die anhand der Fig. 1 beschriebene Einrichtung arbeitet wie folgt:

  • Es möge angenommen sein, dass auf den Stockwerken E10, E11 und E12 eingegebene Abwärtsrufe der einen Aufzugskabine 3 der Aufzugsgruppe zugeteilt wurden und die Aufzugskabine 3 nach Einstieg der Fahrgäste auf Stockwerk E12 nicht ausgelastet ist. Nach Abfahrt vom Stockwerk E12 in Abwärtsrichtung signalisiert der Selektor 10 das Stockwerk Ell, so dass der betreffende Sensor 7 veranlasst wird, die ermittelte Anzahl W der auf dem Stockwerk E11 wartenden Fahrgäste an den Addierer 8 abzugeben. Da gleichzeitig die von der Lastmesseinrichtung 4 ermittelte Anzahl L in der Aufzugskabine 3 befindlicher Fahrgäste dem Addierer 8 zugeführt wird, kann eine Summe (L+W) gebildet und im Komparator 9 mit dem Lastgrenzwert A verglichen werden. Bei (L+W) < A gibt der Komparator 9 ein Signal ab, welches bei Koinzidenz von Stockwerkruf und Selektorsignal für Stockwerk E11 bewirkt, dass am Ausgang des betreffenden UND-Gliedes 11 ein Haltesignal auftritt und die Aufzugskabine 3 am Stockwerk Ell anhält. Wenn jedoch (L+W) > A ist, bewirkt das vom Komparator 9 abgegebene Signal, dass am Ausgang des betreffenden UND-Gliedes 11 ein Durchfahrsignal auftritt und die Aufzugskabine 3 am Stockwerk E11 vorbeifährt. In diesem Fall wird der Ruf vom Stockwerk Ell einer anderen Aufzugskabine der Aufzugsgruppe zugeteilt.
The device described with reference to FIG. 1 works as follows:
  • It may be assumed that downward calls entered on floors E10, E11 and E12 have been assigned to one elevator car 3 of the elevator group and that elevator car 3 is underutilized after passengers have entered floor E12. After departure from the floor E12 in the downward direction, the selector 10 signals the floor Ell, so that the sensor 7 in question is caused to deliver the determined number W of the passengers waiting on the floor E11 to the adder 8. Since the number L of passengers in the elevator car 3 determined by the load measuring device 4 is simultaneously fed to the adder 8, a sum (L + W) can be formed and compared with the load limit value A in the comparator 9. At (L + W) <A, the comparator 9 emits a signal which, if the floor call and the selector signal for floor E11 coincide, causes a stop signal to occur at the output of the relevant AND element 11 and the elevator car 3 to stop at floor Ell. However, if (L + W) > A, the signal emitted by the comparator 9 causes a drive-through signal to occur at the output of the relevant AND element 11 and the elevator car 3 to pass the floor E11. In this case, the call from floor Ell is assigned to another elevator car in the elevator group.

Die anhand der Fig. 2 beschriebene Einrichtung arbeitet in gleicher Weise wie die Einrichtung gemäss Fig. 1, wobei jedoch die dem Addierer 8 nach Abfahrt von einem Stockwerk zuzuführende Anzahl W der auf dem nächsten zu bedienenden Stockwerk wartenden Fahrgäste vom Lastspeicher 12 ermittelt wird.The device described with reference to FIG. 2 works in the same way as the device according to FIG. 1, but the number W of the passengers waiting on the next floor to be served to the adder 8 after departure from one floor is determined by the load store 12.
