Abstract

A group control for double car elevators permits the upper as well as the lower cars to be used at a main stopping floor for travel to both even-numbered and odd-numbered floors. The control has a call memory for each car in which the target calls entered at the main stopping floor and identifying the target floors are stored. A switching circuit has an input connected to the call memories in such a manner that the double car is scheduled in dependence on the allocated call as stopping at floor pairs numbered even-odd or odd-even. An output of the switching circuit is connected to a switching device which excludes either the double cars stopping at floor pairs numbered even-odd or at floor pairs numbered odd-even from the allocation process in the case of a subsequent call to be allocated in order to maximize the possiblilities for coincident stops without losing flexibility.

Description

Die Erfindung betrifft eine Gruppensteuerung für Aufzüge mit Doppelkabinen mit Sofortzuteilung von Zielrufen, wobei die Doppelkabinen aus zwei in einem gemeinsamen Fahrkorbrahmen angeordnete Kabinen gebildet sind, in die an einer Haupthaltestelle wahlweise eingestiegen werden kann, mit auf den Stockwerken angeordneten Rufregistriereinrichtungen, die eine Tastatur für die Eingabe von Rufen für gewünschte Zielstockwerke aufweisen, mit den Aufzügen zugeordneten Rufspeichern, die mit den Rufregistriereinrichtungen verbunden sind, wobei bei der Eingabe eines Rufes ein das Eingabestockwerk und ein das Zielstockwerk kennzeichnender Ruf gespeichert wird, mit in der oberen und unteren Kabine der Doppelkabine vorgesehenen Lastmesseinrichtungen, die mit Lastspeichern in Wirkverbindung stehen, mit den Aufzügen zugeordneten, jeweils das Stockwerk eines möglichen Anhaltens bezeichnenden Selektoren und mit einer Einrichtung, mittels welcher die eingegebenen Rufe den Aufzügen zugeteilt werden, gemäss Oberbegriff des Patentanspruches 1.The invention relates to a group control for elevators with double cabins with immediate assignment of destination calls, the double cabins being formed from two cabins arranged in a common car frame, into which a main stop can optionally be entered, with call registration devices arranged on the floors, which have a keyboard for the Have input of calls for desired target floors, with the call memories assigned to the elevators, which are connected to the call registration devices, with the input storey and a call identifying the destination floor being stored when a call is input, with load measuring devices provided in the upper and lower cabin of the double cabin , which are operatively connected to load stores, with the elevators assigned selectors, each denoting the floor of a possible stopping, and with a device by means of which the entered calls are allocated to the elevators , according to the preamble of claim 1.

Mit der CH-PS 529054 ist eine Steuerung für eine Aufzugsgruppe mit Doppelkabinen bekannt geworden, bei der die Doppelkabinen derartig ausgebildet sind, dass zwei benachbarte Stockwerke gleichzeitig bedient werden können. Hierbei soll das Füllen eines Gebäudes in möglichst kurzer Zeit bei annähernd gleichmässiger Belegung der Doppelkabinen dadurch erreicht werden, dass im Erdgeschoss die Fahrgäste zu geradzahligen Obergeschossen in die obere Kabine, zu den ungeradzahligen in die untere Kabine einsteigen, wobei jeweils die Kabinenrufgeber für die nicht der Kabine zugeordneten Geschosse gesperrt sind. Sobald die Kabine nach Wegfahrt vom Erdgeschoss auf einen Stockwerkruf anhalten muss, wird die Sperrung aufgehoben, so dass der Zusteiger zu beliebigen Stockwerken fahren kann.CH-PS 529054 has disclosed a control system for an elevator group with double cabins, in which the double cabins are designed in such a way that two adjacent floors can be operated simultaneously. In this case, the filling of a building should be achieved in the shortest possible time with approximately even occupancy of the double cabins by the fact that on the ground floor the passengers board the even-numbered upper floors in the upper cabin and the odd-numbered ones in the lower cabin, whereby the cabin callers for those not the Storeys assigned to the cabin are locked. As soon as the cabin has to stop for a floor call after leaving the ground floor, the lock is released so that the boarding person can travel to any floor.

Derartige Aufzüge können bei jeder Fahrt doppelt soviel Fahrgäste befördern wie Aufzüge mit Einzelkabinen. Da weniger gehalten werden muss, kann die gleiche Anzahl Stockwerke in kürzerer Zeit bedient werden, so dass die Förderleistung beträchtlich gesteigert wird. Bei dieser Steuerung kann es jedoch vorkommen, dass Fahrgäste welche die Aufteilung der geradzahligen und ungeradzahligen Stockwerke auf die obere bzw. untere Kabine nicht beachten, das gewünschte Stockwerk nicht erreichen und an einem anderen aussteigen müssen. Als nachteilig muss auch angesehen werden, dass der auf die zusteigenden Fahrgäste in der Haupthaltstelle ausgeübte Zwang die richtige Kabine zu benutzen, nicht nur während der relativ kurzen Zeit des Spitzenverkehrs, sondern auch während der übrigen Zeit besteht.Such lifts can carry twice as many passengers on each trip as lifts with single cabins. Since less has to be kept, the same number of floors can be served in a shorter time, so that the conveying capacity is increased considerably. With this control, however, it can happen that passengers who do not pay attention to the division of the even and odd floors into the upper or lower cabin do not have to reach the desired floor and have to get off at another. It must also be considered a disadvantage that the compulsory use of boarding passengers at the main stop is to use the correct cabin, not only during the relatively short period of peak traffic, but also during the rest of the time.

Bei einer aus der EP-A 0 301 178 bekannten Steuerungseinrichtung für Aufzüge mit Einzel- oder Doppelkabinen, sind auf den Stockwerken Rufregistriereinrichtungen mit Tasten für die Eingabe von Rufen für gewünschte Zielstockwerke angeordnet, wohingegen in den Aufzugskabinen keine Rufknöpfe vorgesehen sind. Auf der Haupthaltestelle sind hierbei auf dem Zugang für die oberen Kabinen der Doppelkabinen Rufregistriereinrichtungen mit Tasten für geradzahlige Zielstockwerke angeordnet, während der Zugang für die unteren Kabinen der Doppelkabinen Rufregistriereinrichtungen mit Tasten für ungeradzahlige Zielstockwerke aufweist. Mit einem weiteren Ausführungsbeispiel wird vorgeschlagen Rufregistriereinrichtungen mit 10er-Tastaturen zu verwenden, wobei auf dem oberen Zugang die Tasten für die ungeradzahligen Zielstockwerke, und auf dem unteren Zugang die Tasten für die geradzahligen Zielstockwerke unwirksam gemacht werden. Auch bei dieser Steuerungseinrichtung muss ein Fahrgast genau überlegen, welchen Zugang er benutzen muss, um das gewünschte Fahrziel zu erreichen. Bei Benutzung eines falschen Zuganges kann der Irrtum allerdings noch vor dem Einsteigen in die Kabine bemerkt werden, so dass durch Wechsel des Zuganges das richtige Fahrziel erreicht werden kann.In a control device for elevators with single or double cabins known from EP-A 0 301 178, call registration devices with keys for entering calls for desired destination floors are arranged on the floors, whereas no call buttons are provided in the elevator cars. At the main stopping point, call registration devices with buttons for even-numbered destination floors are arranged on the access for the upper cabins of the double cabins, while the entry for the lower cabins of the double-cabins has call registration devices with buttons for odd-numbered destination floors. In a further exemplary embodiment it is proposed to use call registration devices with 10-keyboards, the keys for the odd-numbered destination floors being disabled on the upper access and the keys for the even-numbered destination floors being disabled on the lower access. With this control device too, a passenger has to think carefully about which access to use in order to reach the desired destination. If the wrong access is used, the mistake can be noticed before entering the cabin, so that the correct destination can be reached by changing the access.

Mit der EP-A 0 356 731 ist eine für Einzelkabinen beschriebene Gruppensteuerung bekannt geworden, welche als Kriterium für die Zuordnung der Kabinen zu den eingegebenen Rufen die kleinste Wartezeit aller Fahrgäste anwendet. Bei dieser Steuerung können die Fahrziele beispielsweise durch mit der EP-A 0 320 583 vorgeschlagene Rufregistrier- und Anzeigeeinrichtungen ebenfalls schon auf den Stockwerken eingegeben werden. Sofort nach der Registrierung und Übertragung eines Rufes in einen nach Eingabe- und Zielstockwerke gegliederten Rufspeicher, ermittelt ein Rechner in Form eines Mikroprozessors aus aufzugsspezifischen Daten für jede Kabine eine Bedienungskosten genannte Summe, die der Wartezeit entspricht, welche bei der Bedienung des Rufes für die Fahrgäste entstehen würde. Die Bedienungskosten werden unmittelbar nach der Berechnung in ein Kostenregister übertragen und anschliessend sofort mittels einer Vergleichseinrichtung mit den Bedienungskosten der anderen Aufzüge verglichen. Hierbei wird in einem Zuteilungsspeicher desjenigen Aufzuges eine Zuteilungsanweisung gespeichert, der die geringsten Bedienungskosten aufweist. Unmittelbar nach der auf diese Weise erfolgten Zuordnung Kabine/Ruf, wird in einem Anzeigefeld der betätigten Rufregistrier- und Anzeigeeinrichtung der betreffende Aufzug und dessen Lage angezeigt, so dass der Fahrgast sich rechtzeitig zur zugeordneten Schachttür begeben kann.EP-A 0 356 731 discloses a group control described for individual cabins, which uses the shortest waiting time of all passengers as a criterion for the assignment of the cabins to the calls entered. With this control, the travel destinations can also be entered on the floors, for example by means of call registration and display devices proposed with EP-A 0 320 583. Immediately after the registration and transmission of a call into a call memory structured according to the input and destination floors, a computer in the form of a microprocessor determines an amount for each cabin, based on elevator-specific data, which corresponds to the waiting time, which corresponds to the waiting time for the passengers to service the call would arise. The operating costs are transferred to a cost register immediately after the calculation and then immediately compared with the operating costs of the other elevators by means of a comparison device. In this case, an allocation instruction that has the lowest operating costs is stored in an allocation memory of the elevator. Immediately after the car / call assignment has been made in this way, the elevator and its location in question are displayed in a display field of the activated call registration and display device, so that the passenger can go to the assigned landing door in good time.

Der Erfindung liegt die Aufgabe zugrunde, die im Stand der Technik anfangs genannten Steuerungseinrichtungen derart zu verbessern, dass bei Aufzügen mit Doppelkabinen in der Haupthaltestelle sowohl obere als auch untere Kabinen der Doppelkabinen für Fahrten zu geradzahligen und ungeradzahligen Stockwerken benutzt werden können.The invention has for its object to improve the control devices initially mentioned in the prior art in such a way that both elevators and lower cabins of the double cabins can be used for trips to even and odd floors in elevators with double cabins in the main station.

Diese Aufgabe wird durch die im Patentanspruch 1 gekennzeichnete Erfindung gelöst. Hierbei ist der oberen und unteren Kabine einer Doppelkabine je ein Rufspeicher zugeordnet, in dem die auf der Haupthaltestelle eingegebenen, die Zielstockwerke kennzeichnenden Rufe gespeichert sind. Ein Schaltkreis steht eingangsseitig derart mit den Rufspeichern in Verbindung, dass in Abhängigkeit eines zugeteilten Rufes die betreffende Doppelkabine als an gerad- ungeradzahligen oder ungerad- geradzahligen Stockwerkpaaren haltend festgelegt wird. Ausgangsseitig ist der Schaltkreis über eine Schalteinrichtung mit der Vergleichseinrichtung verbunden, so dass in Abhängigkeit eines weiteren, noch zuzuteilenden Rufes entweder die an gerad- ungeradzahligen oder die an ungeradgeradzahligen Stockwerkpaaren haltenden Doppelkabinen nicht am Vergleichs- und Zuteilungsverfahren teilnehmen können. Ein Ruf wird unmittelbar nach der Eingabe zugeteilt, wobei der betreffende Aufzug und dessen Lage auf einem Anzeigefeld der betätigten Rufregistriereinrichtung angezeigt wird.This object is achieved by the invention characterized in claim 1. In this case, a call memory is assigned to the upper and lower cabin of a double cabin, in which the calls entered at the main station and identifying the destination floors are stored. A On the input side, the circuit is connected to the call memories in such a way that, depending on an assigned call, the double cabin in question is defined as holding on even-odd or odd-numbered floor pairs. On the output side, the circuit is connected to the comparison device via a switching device, so that depending on a further call that is yet to be allocated, either the double cabins on odd-numbered floors or those on odd-numbered floor pairs cannot participate in the comparison and allocation process. A call is assigned immediately after the entry, the elevator in question and its position being displayed on a display panel of the activated call registration device.

Die mit der Erfindung erzielten Vorteile sind darin zu sehen, dass die Fahrgäste in einer Haupthaltestelle nicht mehr zu überlegen brauchen, ob sie in die obere oder untere Kabine einer Doppelkabine einsteigen müssen um das gewünschte Stockwerk zu erreichen, da die Steuerung in der Lage ist, sowohl auf dem oberen als auch auf dem unteren Zugang eine geeignete Kabine zur Verfügung zu stellen. Hierbei bleibt der anfänglich erwähnte Vorteil, dass Doppelkabinenaufzüge bei Fahrten von der Haupthaltestelle aus für Aussteiger weniger anhalten müssen als Einzelkabinenaufzüge, voll erhalten. Auch die Bevorzugung von koinzidenten Halten ist weiterhin möglich, wobei die Möglichkeit beim gleichen Umlauf gerad- ungerad oder ungerad- gerad zu halten die Verfügbarkeit der Kabinen verbessert und Wartezeiten verkürzt.The advantages achieved with the invention can be seen in the fact that the passengers in a main bus stop no longer have to consider whether they have to get into the upper or lower cabin of a double cabin in order to reach the desired floor, since the control system is able to to provide a suitable cabin on both the upper and lower access. The initially mentioned advantage that double cabin lifts have to stop less for dropouts when traveling from the main stop than single cabin lifts remains fully intact. The preference for coincidental stops is also still possible, with the possibility of keeping odd or even odd in the same circulation improves the availability of the cabins and shortens waiting times.

In der Fig. 1 ist mit 1 ein Aufzugsschacht eines Aufzuges A einer aus mehreren Aufzügen bestehenden Aufzugsgruppe bezeichnet. Eine Fördermaschine 2 treibt über ein Förderseil 3 eine im Aufzugsschacht 1 geführte, aus zwei in einem gemeinsamen Fahrkorbrahmen angeordnete Kabinen 5, 6 gebildete Doppelkabine 4 an, wobei gemäss der als Beispiel gewählten Aufzugsanlage sechzehn Stockwerke E1 bis E16 bedient werden. Der Abstand der beiden Kabinen voneinander ist so gewählt, dass er mit dem Abstand zweier benachbarter Stockwerke übereinstimmt. Eine beispielsgemäss im Erdgeschoss vorgesehene Haupthaltestelle E0 weist einen unteren Zugang L1 zur unteren Kabine 5 und einen oberen Zugang L2 zur oberen Kabine 6 der Doppelkabine 4 auf, wobei der obere Zugang L2 durch eine Rolltreppe 7 mit dem unteren Zugang L1 verbunden ist. Die Fördermaschine 2 wird von einer aus der EP-B 0 026 406 bekannten Antriebssteuerung gesteuert, wobei die Sollwerterzeugung, die Regelfunktion und die Stoppeinleitung mittels eines Mikrocomputersystems 8 realisiert werden, das mit Mess- und Stellgliedern 9 der Antriebssteuerung in Verbindung steht. Das Mikrocomputersystem 8 berechnet ausserdem wie beispielsweise aus der EP-A 0 356 731 bekannt, aus aufzugsspezifischen Daten eine der Wartezeit aller Fahrgäste entsprechende Summe, auch Bedienungskosten genannt, die dem Rufzuteilungsverfahren zugrunde gelegt wird. Die Kabinen 5, 6 weisen Lastmesseinrichtungen 10 auf, die ebenfalls mit dem Mikrocomputersystem 8 verbunden sind. Auf den Stockwerken sind beispielsweise aus der EP-A 0 320 583 bekannte Rufregistrierund Anzeigeeinrichtungen 11 vorgesehen, die 10er-Tastaturen aufweisen, mittels welchen Rufe für Fahrten zu gewünschten Zielstockwerken eingegeben werden können. Bei der beispielsweise angenommenen Methode der seriellen Dateneingabe sind die Rufregistrier- und Anzeigeeinrichtungen 11 über nicht dargestellte serielle Interfacebausteine und einen seriellen Datenleiter 12 mit den Mikrocomputersystemen 8 verbunden. Die Mikrocomputersysteme 8 der einzelnen Aufzüge der Gruppe stehen über eine aus der EP-B 0 050 304 bekannte Vergleichseinrichtung 13 und ein aus der EP-B 0 050 305 bekanntes Partyline-Übertragungssystem 14 miteinander in Verbindung.1, 1 denotes an elevator shaft of an elevator A of an elevator group consisting of several elevators. A conveyor machine 2 drives, via a conveyor cable 3, a double cabin 4, which is guided in the elevator shaft 1 and is formed from two cabins 5, 6 arranged in a common car frame, sixteen floors E1 to E16 being operated according to the elevator system chosen as an example. The distance between the two cabins is chosen so that it matches the distance between two adjacent floors. A main stop E0 provided, for example, on the ground floor has a lower entrance L1 to the lower cabin 5 and an upper entrance L2 to the upper cabin 6 of the double cabin 4, the upper entrance L2 being connected to the lower entrance L1 by an escalator 7. The carrier 2 is controlled by a drive control known from EP-B 0 026 406, the setpoint generation, the control function and the start of the stop being implemented by means of a microcomputer system 8 which is connected to measuring and actuating elements 9 of the drive control. The microcomputer system 8 also calculates, as is known, for example, from EP-A 0 356 731, from elevator-specific data a sum corresponding to the waiting time of all passengers, also called service costs, which is used as the basis for the call allocation process. The cabins 5, 6 have load measuring devices 10, which are also connected to the microcomputer system 8. Call registers known from EP-A 0 320 583, for example, are on the floors Display devices 11 are provided, which have 10-keyboards, by means of which calls can be entered for trips to desired target floors. In the method of serial data input assumed, for example, the call registration and display devices 11 are connected to the microcomputer systems 8 via serial interface modules (not shown) and a serial data conductor 12. The microcomputer systems 8 of the individual elevators in the group are connected to one another via a comparison device 13 known from EP-B 0 050 304 and a party line transmission system 14 known from EP-B 0 050 305.

Der in Fig. 2 schematisch dargestellte Teil des beispielsweise dem Aufzug A zugeordneten Mikrocomputersystems 8 weist sowohl für die untere als auch für die obere Kabine 5, 6 einer Doppelkabine 4 je einen Rufspeicher 20, 21 auf, welchen je ein Zuteilungsspeicher 22, 23 zugeordnet ist. Die Rufspeicher 20, 21 und Zuteilungsspeicher 22, 23 haben für jede Fahrtrichtung der Anzahl der Stockwerke entsprechende Speicherplätze, wobei lediglich die der Aufwärts-Fahrtrichtung zugeordneten Speicher dargestellt sind. Die Rufspeicher 20, 21 bestehen je aus einem ersten Speicher 20.1, 21.1 und einem zweiten Speicher 20.2, 21.2, wobei in den ersten Speichern 20.1, 21.1 die die Rufeingabestockwerke und in den zweiten Speichern 20.2, 21,2 die die Zielstockwerke kennzeichnenden Rufe gespeichert werden. Mit 24 ist ein für Speicherung der Bedienungskosten bestimmtes Bedienungskostenregister bezeichnet. Ein der unteren Kabine 5 zugeordneter erster Selektor 25 und ein der oberen Kabine 6 zugeordneter zweiter Selektor 26 in Form von weiteren Registern, bilden den Stockwerknummern entsprechende Adressen, mittels welchen die Speicherplätze der Speicher 20, 21 adressiert werden können. Die Selektoren 25, 26 zeigen jeweils dasjenige Stockwerk an auf welchem die Doppelkabine 4 mit der unteren bzw. oberen Kabine 5, 6 noch anhalten könnte, zu welchem Zweck bei der Aufwärtsfahrt der zweite Selektor 26 dem ersten und bei der Abwärtsfahrt der erste Selektor 25 dem zweiten um ein Stockwerk vorauseilt. Die Rufspeicher 20, 21 und die Zuteilungsspeicher 22, 23 sind Schreib-Lesespeicher, die, wie auch Register 24, 25, 26, mit dem Bus 27 des Mikrocomputersystems 8 verbunden sind. Die gemäss Beispiel Fig. 2 in den Rufspeichern 20, 21 gespeicherten Rufe und die in den Zuteilungsspeichern 22, 23 gespeicherten Zuteilungsanweisungen sind symbolisch mit "1" gekennzeichnet, wobei die Zuteilungsanweisungen ausdrücken, dass das Rufpaar L1/E5 der unteren Kabine 5 und das Rufpaar L2/E8 der oberen Kabine 6 der Doppelkabine 4 des Aufzuges A zugeteilt ist. Mit 28 ist ein Lastspeicher, mit 29 ein Türzeitspeicher und mit 30 ein Fahrzeitspeicher bezeichnet, die ebenfalls mit dem Bus 27 des Mikrocomputersystems 8 verbunden sind. Die aus der vorstehend zitierten EP-A 0 356 731 bekannten Speicher 28, 29, 30 sind Schreib-Lesespeicher, in welchen Daten für die Bedienungskostenberechnung gespeichert sind. Im Lastspeicher 28 sind pro Stockwerk Lastwerte in Form einer Anzahl Personen gespeichert, die sich bei einem zukünftigen Halt oder der Vorbeifahrt an einem Stockwerk in der jeweiligen unteren oder oberen Kabine 5, 6 befinden, und die aufgrund der eingegebenen Rufe errechnet werden. Hierbei können aus fehlerhaften Rufeingaben gebildete Lastwerte durch Vergleich mit den durch die Lastmesseinrichtungen 10 ermittelten Werten korrigiert werden. Im Türzeitspeicher 29 sind für jedes Stockwerk die Türöffnungs- und -schliesszeiten des betreffenden Aufzuges gespeichert, während im Fahrtzeitspeicher 30 die Fahrtzeiten der betreffenden Doppelkabine 4 zwischen jeweils einem bestimmten Stockwerk und jedem anderen Stockwerk gespeichert sind. Das Bedienungskostenregister 24 ist über eine Schalteinrichtung 31 in Form von Tristate-Buffern mit der Vergleichseinrichtung 13 verbunden, wobei die Aktivierungsanschlüsse der Tristate-Buffer am Ausgang eines nachstehend näher beschriebenen Schaltkreises 32 angeschlossen sind.The part of the microcomputer system 8, which is schematically shown in FIG. 2, for example, has a call memory 20, 21 for the lower as well as for the upper cabin 5, 6 of a double cabin 4, to which an allocation memory 22, 23 is assigned . The call memories 20, 21 and allocation memories 22, 23 have memory locations corresponding to the number of floors for each direction of travel, only the memories associated with the upward direction of travel being shown. The call memories 20, 21 each consist of a first memory 20.1, 21.1 and a second memory 20.2, 21.2, the calls characterizing the storey storeys in the first memories 20.1, 21.2 and the calls characterizing the destination floors being stored in the second memories 20.2 . 24 denotes an operating cost register intended for storing the operating costs. A first selector 25 assigned to the lower car 5 and a second selector 26 assigned to the upper car 6 in the form of further registers form addresses corresponding to the floor numbers, by means of which the memory locations of the memories 20, 21 can be addressed. The selectors 25, 26 each show the floor on which the double cabin 4 with the lower or upper cabin 5, 6 could still stop, for which purpose the second selector 26 for the first and the first selector 25 for the downward travel the second by one floor. The call memory 20, 21 and the allocation memories 22, 23 are read-write memories which, like also registers 24, 25, 26, are connected to the bus 27 of the microcomputer system 8. The calls stored in the call memories 20, 21 according to example FIG. 2 and the allocation instructions stored in the allocation memories 22, 23 are symbolically marked with "1", the allocation instructions expressing that the call pair L1 / E5 of the lower car 5 and the call pair L2 / E8 of the upper cabin 6 of the double cabin 4 of elevator A is allocated. 28 denotes a load memory, 29 a door time memory and 30 a travel time memory, which are also connected to the bus 27 of the microcomputer system 8. The memories 28, 29, 30 known from EP-A 0 356 731 cited above are read-write memories in which data for the calculation of the service costs are stored. Load values are stored in the load memory 28 per floor in the form of a number of people who are at a future stop or when passing a floor in the respective lower or upper cabin 5, 6, and which are calculated on the basis of the calls entered. In this case, load values formed from incorrect call inputs can be corrected by comparison with the values determined by the load measuring devices 10. The door opening and closing times of the elevator concerned are stored in the door time memory 29 for each floor, while the journey times of the relevant double cabin 4 between a particular floor and every other floor are stored in the travel time memory 30. The service cost register 24 is connected to the comparison device 13 via a switching device 31 in the form of tristate buffers, the activation connections of the tristate buffers being connected to the output of a circuit 32 described in more detail below.

Der Schaltkreis 32 besteht aus einem ODER-Gatter 33, das sechs Eingänge aufweist, welche jeweils sechs aufeinanderfolgenden Stockwerken zugeordnet sind. Bei einer ersten Ausführung gemäss Fig. 2, sind drei der Eingänge jeweils mit Ausgängen der den ungeradzahligen Stockwerken zugeordneten Speicherzellen des zweiten Speichers 21.2 der oberen Kabine 6 verbunden, und die anderen drei Eingänge jeweils an den Ausgängen der den geradzahligen Stockwerken zugeordneten Speicherzellen des zweiten Speichers 20.2 der unteren Kabine 5 angeschlossen. Bei einer zweiten Ausführung dagegen, sind wie in der Fig. 3 dargestellt, drei der Eingänge des ODER-Gatters 33 jeweils mit Ausgängen der den geradzahligen Stockwerken zugeordneten Speicherzellen des zweiten Speichers 21.2 der oberen Kabine 6 verbunden, und die anderen drei Eingänge jeweils an den Ausgängen der den ungeradzahligen Stockwerken zugeordneten Speicherzellen des zweiten Speichers 20.2 der unteren Kabine 5 angeschlossen. Der Ausgang des ODER-Gatters 33 steht mit den Aktivierungsanschlüssen der Tristate-Buffer in Verbindung. Der beispielsweise aufgrund eines Programmes vom Mikrocomputersystem 8 gebildete Schaltkreis 32 wird jeweils bei Speicherung eines zuzuteilenden Rufes aktiviert. Hierbei werden in Abhängigkeit vom betreffenden Zielstockwerk und vom Speicher, in welchen der Ruf übertragen wurde, entweder die Verbindungen gemäss der ersten oder zweiten Ausführung derart hergestellt, dass das Zielstockwerk dem mittleren von drei durch den Schaltkreis 32 festgelegten Stockwerkpaaren zugeordnet ist.The circuit 32 consists of an OR gate 33, which has six inputs, each of which is assigned to six successive floors. In a first execution according to 2, three of the inputs are each connected to outputs of the memory cells of the second memory 21.2 of the upper cabin 6 which are assigned to the odd-numbered floors, and the other three inputs are each connected to the outputs of the memory cells of the second memory 20.2 of the lower cabin 5 which are assigned to the even-numbered floors connected. In a second embodiment, however, as shown in FIG. 3, three of the inputs of the OR gate 33 are each connected to outputs of the memory cells of the second memory 21.2 of the upper cabin 6 assigned to the even floors, and the other three inputs are each connected to the Outputs of the memory cells assigned to the odd-numbered floors of the second memory 20.2 of the lower cabin 5 are connected. The output of the OR gate 33 is connected to the activation connections of the tristate buffers. The circuit 32 formed by the microcomputer system 8, for example on the basis of a program, is activated in each case when a call to be allocated is stored. Depending on the target floor in question and the memory in which the call was transmitted, either the connections according to the first or second embodiment are established in such a way that the target floor is assigned to the middle of three floor pairs defined by the circuit 32.

In der Fig. 4 sind für drei Aufzüge A, B und C einer Aufzugsgruppe nur die zweiten Speicher 20.2, 21.2 der unteren bzw. der oberen Kabine 5, 6 der betreffenden Doppelkabine 4 dargestellt. Die Verteilung der auf dem unteren bzw. oberen Zugang L1, L2 (Fig. 1) eingegebenen, mit "1" gekennzeichneten Zielrufe auf die zweiten Speicher 20.2, 21.2 wird anhand eines Beispieles in der nachfolgenden Funktionsbeschreibung näher erläutert. Hierbei wird im Bereich von jeweils drei benachbarten Stockwerkpaaren die Doppelkabine 4 des Aufzuges A an gerad- ungeradzahligen Stockwerkpaaren, und die Doppelkabine 4 des Aufzuges B an ungerad- geradzahligen Stockwerkpaaren haltend festgelegt, während die Doppelkabine 4 des Aufzuges C noch nicht festgelegt ist.In FIG. 4, only the second stores 20.2, 21.2 of the lower and the upper cab 5, 6 of the respective double cab 4 are shown for three elevators A, B and C of an elevator group. The distribution of the destination calls entered on the lower or upper access L1, L2 (FIG. 1) and marked with "1" between the second memories 20.2, 21.2 is explained in more detail using an example in the following functional description. The double cabin 4 of elevator A on even-odd-numbered floor pairs and the double cabin 4 of elevator B on odd-numbered floor pairs are located in the area of three adjacent floor pairs holding fixed, while the double cabin 4 of the elevator C is not yet fixed.

Die vorstehend beschriebene Gruppensteuerung arbeitet wie folgt:The group control described above works as follows:

Bei der Eingabe eines Rufes wird die Adresse des Rufeingabestockwerkes und die des Zielstockwerkes über den seriellen Datenleiter 12 in die Mikrocomputersysteme 8 aller Aufzüge übertragen, wobei jeweils immer nur eine Rufregistrier- und Anzeigeeinrichtung 11 auf den seriellen Datenleiter 12 zugreifen kann. Wird der Ruf auf dem unteren oder oberen Zugang L1, L2 der Haupthaltestelle E0 eingegeben, so interpretieren die Mikroprozessoren der Mikrocomputersysteme 8 die Adresse des Rufeingabestockwerkes derart, dass das betreffende Rufpaar entweder nur in die Rufspeicher der oberen oder nur der unteren Kabinen eingeschrieben wird (Beispiel Fig. 2, L2/E8). Nun wird beispielsweise angenommen, dass auf dem oberen Zugang L2 Rufe für die Stockwerke E8 und E7, und auf dem unteren Zugang L1 Rufe für die Stockwerke E5 und E6 eingegeben werden. Es wird weiterhin angenommen, dass bei logisch "0" am Ausgang des Schaltkreises 32 die Schalteinrichtung 31 leitend ist. Nach der Eingabe des Rufes für Stockwerk E8 auf dem oberen Zugang L2 wird der Ruf in die den oberen Kabinen 6 zugeordneten Rufspeicher 21 aller Aufzüge übertragen, wobei der Schaltkreis 32 gemäss erster Ausführung Fig. 2 aktiviert wird. Da der Ausgang der dem Stockwerk E8 zugeordneten Speicherzelle nicht mit einem Eingang des ODER-Gatters 33 verbunden ist, und in den Rufspeichern 20, 21 aller Aufzüge für die Stockwerke E5-E8 noch kein Ruf gespeichert sein möge, bleibt die Schalteinrichtung 31 im leitenden Zustand, so dass alle Aufzüge am Vergleich teilnehmen können. Nun werden bei allen Aufzügen gemäss der bereits genannten EP-A 0 356 731 die Bedienungskosten für das neue Rufpaar berechnet. Unmittelbar nach der Berechnung werden die Bedienungskosten in die Bedienungskostenregister 24 übertragen und mittels der beispielsweise vorgeschlagenen Vergleichseinrichtung 13 gemäss EP-B 0 050 304 miteinander verglichen. Es möge angenommen sein, dass Aufzug A die kleinsten Bedienungskosten aufweist, so dass in dessen Zuteilungsspeicher 23 bei den Stockwerken L2 und E8 eine Zuteilungsanweisung eingeschrieben wird (Fig. 2). Danach wird bei den Aufzügen ohne Zuteilungsanweisung das neue Rufpaar gelöscht. Mit der Zuteilung des Rufes für Stockwerk E8 ist die Doppelkabine 4 des Aufzuges A im Bereich von drei benachbarten gerad- ungeradzahligen Stockwerkpaaren jeweils mit der oberen Kabine 6 an geradzahligen Stockwerken haltend, festgelegt.When a call is entered, the address of the call input storey and that of the destination storey are transmitted to the microcomputer systems 8 of all elevators via the serial data conductor 12, only one call registration and display device 11 being able to access the serial data conductor 12 at a time. If the call is entered on the lower or upper access L1, L2 of the main stop E0, the microprocessors of the microcomputer systems 8 interpret the address of the call input storey in such a way that the call pair in question is either only written into the call memory of the upper or only the lower cabins (example Fig. 2, L2 / E8). Now it is assumed, for example, that calls for the floors E8 and E7 are entered on the upper entrance L2 and calls for the floors E5 and E6 on the lower entrance L1. It is further assumed that when the output of circuit 32 is logic "0", switching device 31 is conductive. After the call for floor E8 has been entered on the upper access L2, the call is transferred to the call memories 21 of all the elevators assigned to the upper cabins 6, the circuit 32 being activated in accordance with the first embodiment in FIG. 2. Since the output of the memory cell assigned to the floor E8 is not connected to an input of the OR gate 33 and no call may yet be stored in the call memories 20, 21 of all elevators for the floors E5-E8, the switching device 31 remains in the conductive state so that all elevators can take part in the comparison. Now the operating costs for the new call pair are calculated for all elevators in accordance with EP-A 0 356 731 already mentioned. Immediately after the calculation, the service costs are transferred to the service cost register 24 and to one another using the comparison device 13 proposed, for example, in accordance with EP-B 0 050 304 compared. It may be assumed that elevator A has the lowest operating costs, so that an allocation instruction is written into its allocation memory 23 on floors L2 and E8 (FIG. 2). The new call pair is then deleted from the lifts without any assignment instructions. With the allocation of the call for floor E8, the double car 4 of the elevator A is fixed in the area of three adjacent even-odd-numbered floor pairs, each holding the upper car 6 on even-numbered floors.

Bei der Eingabe des Rufes für Stockwerk E7 auf dem oberen Zugang L2 und nach Übertragung des Rufes in die den oberen Kabinen 6 zugeordneten Rufspeicher 21 aller Aufzüge, wird der Ausgang des ODER-Gatters 33 beim Aufzug A (Fig. 2) logisch "1", so dass die Schalteinrichtung 31 sperrt und der Aufzug A nicht am Zuteilungsverfahren teilnehmen kann. Bei den übrigen Aufzügen wird der Schaltkreis 32 gemäss der zweiten Ausführung Fig. 3 aktiviert, wobei die Schalteinrichtung 31 nicht gesperrt ist. Beim nun folgenden Zuteilungsverfahren möge der Ruf für Stockwerk E7 dem Aufzug B zugeteilt werden (Fig. 3), so dass die Doppelkabine 4 dieses Aufzuges im Bereich von drei benachbarten ungerad- geradzahligen Stockwerkpaaren jeweils mit der oberen Kabine 6 an ungeradzahligen Stockwerken haltend, festgelegt wird. Wird nun der Ruf für Stockwerk E5 auf dem unteren Zugang L1 eingegeben, so kann Aufzug B nicht an der Zuteilungsprozedur teilnehmen, wobei der Ruf beispielsweise dem Aufzug A zugeteilt wird (Fig. 2). Der ebenfalls auf dem unteren Zugang L1 eingegebene Ruf für Stockwerk E6 bewirkt, dass Aufzug A von der Zuteilung ausgeschlossen wird. Dieser Ruf möge beispielsgemäss dem Aufzug B zugeteilt sein (Fig. 3). Sofort nach einer Rufzuteilung wird in einem Anzeigefeld der betätigten Rufregistrier- und Anzeigeeinrichtung dem Fahrgast der zugeteilte Ruf und dessen Lage angezeigt. Ist für ein Stockwerkpaar entweder nur für die untere oder nur für die obere Kabine einer Doppelkabine ein Zielruf gespeichert, so wird für die Stoppeinleitung im ersten Fall der erste Selektor 25 und im zweiten Fall der zweite Selektor 26 wirksam (Fig. 4, Aufzug A, E5/E6, E7/E8).When the call for floor E7 is entered on the upper access L2 and after the call has been transmitted to the call memories 21 of all elevators assigned to the upper cabins 6, the output of the OR gate 33 at the elevator A (FIG. 2) becomes logic "1" , so that the switching device 31 blocks and the elevator A cannot participate in the allocation process. In the other lifts, the circuit 32 is activated according to the second embodiment, FIG. 3, the switching device 31 not being blocked. In the allocation procedure that now follows, the call for floor E7 should be assigned to elevator B (FIG. 3), so that the double cabin 4 of this elevator is fixed in the region of three adjacent odd-numbered floor pairs, each with the upper cabin 6 holding on odd-numbered floors . If the call for floor E5 is now entered on the lower entrance L1, elevator B cannot take part in the allocation procedure, the call being allocated to elevator A, for example (FIG. 2). The call for floor E6 also entered on the lower entrance L1 has the effect that elevator A is excluded from the allocation. According to the example, this call may be assigned to elevator B (FIG. 3). Immediately after a call has been allocated, the passenger is shown the assigned call and its location in a display field of the activated call registration and display device. If a destination call is stored for a floor pair either only for the lower or only for the upper cabin of a double cabin, the first selector is used for initiating the stop in the first case 25 and in the second case the second selector 26 is effective (FIG. 4, elevator A, E5 / E6, E7 / E8).

Um zu erreichen, dass beim Einsteigen auf der Haupthaltestelle E0 während des Spitzenverkehrs die unteren und oberen Kabinen 5, 6 gleichmässig gefüllt werden, können optische Anzeigeeinrichtungen vorgesehen werden, die in Abhängigkeit der bereits zugeteilten Zielrufe den neuankommenden Fahrgästen die vorteilhafteren Kabinen signalisieren. So können beispielsweise auf den Zugängen L1 und L2 Hinweistafeln angeordnet werden, auf welchen angezeigt wird, ob bestimmte Zielstockwerke durch Benutzung von unteren oder oberen Kabinen 5, 6 schneller erreicht werden können.In order to ensure that the lower and upper cabins 5, 6 are filled evenly when boarding at the main stop E0 during peak traffic, optical display devices can be provided which signal the more advantageous cabins to the newly arriving passengers depending on the destination calls already allocated. For example, information boards can be arranged on the entrances L1 and L2, on which it is displayed whether certain target floors can be reached more quickly by using lower or upper cabins 5, 6.
