Abstract

A group elevator control wherein the calls entered by means of call registering devices at a main floor for desired destination floors are assigned to the next arriving or already present car, and indicated so that no doubts can arise for passengers, whose calls had been acknowledged, in the choice of the correct car. A locking circuit responds to the presence of several cars at the main floor by only opening the doors of one elevator and assigning the entered calls to this elevator. The call registering devices are blocked at a time dependent on the start of the door closure or after the entering of a certain number of calls, by means of an inhibiting circuit and released again at the departure of the respective car. During the retention cycle, an indicator element, arranged in an indicator panel of the call registering devices, signals the blocking.

Description

Die Erfindung betrifft eine Einrichtung für die Steuerung des Verteilverkehrs in einer Haupthaltestelle bei Aufzugsgruppen gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for controlling the distribution traffic in a main stop for elevator groups according to the preamble of claim 1.

Aufzüge mit Steuerungsprogrammen für Aufwärtsspitzenverkehr werden z.B. in hohen Bürogebäuden oder anderen Geschäftshäusern eingesetzt, wobei beabsichtigt ist, das Gebäude bei Arbeitsbeginn in möglichst kurzer Zeit zu füllen. Wie beispielsweise aus der US-PS 2 492 010 ersichtlich, werden hierbei die Kabinen in der Haupthaltestelle, welche in diesem Fall das Erdgeschoss ist, bereitgestellt und bei Vollast oder in bestimmten Zeitabständen in Aufwärtsrichtung abgesendet. Nach Erledigung des höchsten Rufes kehren die Kabinen zur Haupthaltestelle zurück, wobei je nach Steuerungsprogramm etwa vorhandene Abwärtsrufe vollumfänglich, reduziert oder überhaupt nicht bedient werden. Das Steuerungsprogramm für den Aufwärtsspitzenverkehr kann hierbei mittels Verkehrs- überwachungseinrichtungen, wie beispielsweise aus der CH-PS 342 352 bekannt, ausgelöst werden.Elevators with control programs for upward peak traffic are e.g. used in tall office buildings or other commercial buildings, the intention being to fill the building as soon as possible when starting work. As can be seen, for example, from US Pat. No. 2,492,010, the cabins are provided in the main stop, which in this case is the ground floor, and are sent upwards at full load or at certain intervals. After the highest call has been dealt with, the cabins return to the main stop, whereby depending on the control program, any downward calls that are present are fully, reduced or not served at all. The control program for the upward peak traffic can be triggered here by means of traffic monitoring devices, as known for example from CH-PS 342 352.

Sind in den Kabinen der vorstehend beschriebenen Aufzüge wie allgemein üblich Rufknöpfe angeordnet, so ist gewährleistet, dass die in der Haupthaltestelle eingestiegenen Fahrgäste das eingegebene Zielstockwerk erreichen. Mit der US-A- 3 374 864 ist eine Gruppensteuerung bekanntgeworden, bei der das gewünschte Zielstockwerk jedoch bereits auf dem Einsteigestockwerk eingegeben werden kann. Zu diesem Zweck sind auf den Stockwerken Rufknöpfe für jeweils alle anderen Stockwerke angeordnet, während in der Kabine keine Rufknöpfe vorgesehen sind. Die für drei Stockwerke und zwei Aufzüge konzipierte Steuerung arbeitet in der Weise, dass die für ein Zielstockwerk bestimmte Kabine bei Ankunft auf dem Einsteigestockwerk durch eine optische Anzeigevorrichtung das Zielstockwerk in Form der Stockwerknummer bekanntgibt, damit nicht fälschlicherweise Fahrgäste einsteigen, die zu anderen Zielstockwerken wollen. Bei Anwendung einer derartigen Rufeingabetechnik für Aufzugsgruppen mit Steuerungsprogrammen für den Aufwärtsspitzenverkehr treten insbesondere bei Gebäuden mit vielen Stockwerken und grossem Verkehrsanfall beim Verteilverkehr in der Haupthaltestelle Schwierigkeiten auf, die in der Zuteilung der Rufe zu den Kabinen und der entsprechenden Information der Fahrgäste zu suchen sind, und für welche die letztgenannte Druckschrift keine Lösung angibt.If, as is customary, call buttons are arranged in the cabins of the lifts described above, it is ensured that the passengers boarded in the main stop reach the destination floor entered. With US-A-3 374 864 a group control has become known, in which the desired destination floor can already be entered on the entry floor. For this purpose, call buttons for all other floors are arranged on the floors, while no call buttons are provided in the cabin. The control system, which is designed for three floors and two elevators, works in such a way that the cabin intended for a destination floor announces the destination floor in the form of the floor number by an optical display device when it arrives on the entry floor, so that passengers who want to go to other destination floors do not get in wrongly. When using such a call input technology for elevator groups with control programs for the upward peak traffic, difficulties arise in particular in buildings with many floors and a large volume of traffic when distributing traffic in the main stop, which are to be found in the allocation of the calls to the cabins and the corresponding information for the passengers, and for which the latter publication does not provide a solution.

Mit der EP-A1 0 132 405 ist eine Steuerungseinrichtung bekannt geworden, bei der ähnlich wie bei der US-A 3 374 864 auf einem Stockwerk ein Ruf für ein gewünschtes Zielstockwerk eingegeben werden kann, der dann einer bestimmten Kabine zugeteilt wird. Treffen nun ein oder mehrere Kabinen, denen dieser Zielruf nicht zugeteilt wurde, früher oder gleichzeitig auf dem Eingabestockwerk ein, so wird auch diesen Kabinen der Zielruf zugeteilt. Da der Fahrgast bei dieser Einrichtung die zugeteilte Kabine nicht kennt, kann er mit dieser Methode in jedem Fall das gewünschte Zielstockwerk erreichen. Gemäss einem Rufzuteilungskriterium vorstehend beschriebener Einrichtung, wird bei Vorhandensein einer Kabine auf einem Stockwerk, ein auf diesem Stockwerk eingegebener Zielruf dieser Kabine zugeteilt. Bei Anwendung dieses Zuteilungskriteriums für die Abwicklung von Spitzenverkehr von einer Haupthaltestelle aus, muss damit gerechnet werden, dass zu der einen Kabine in der Haupthaltestelle weitere Kabinen hinzukommen, so dass die eingegebenen Zielrufe gemäss Steuerungsmodus auch diesen Kabinen zugeteilt werden müssen. Die Fahrgäste werden sich somit auf mehrere Kabinen verteilen, so dass ein rationeller Betrieb, der möglichst maximal gefüllte Kabinen voraussetzt, nicht verwirklicht werden kann. Ausserdem müssen wegen der Mehrfachzuteilung entweder Leerfahrten der nicht benutzten Kabinen oder ein zusätzlicher Steuerungsaufwand zwecks Löschung nicht mehr benötigter Kabinenrufe in Kauf genommen werden.EP-A1 0 132 405 discloses a control device in which, similarly to US Pat. No. 3,374,864, a call for a desired destination floor can be entered on a floor, which call is then allocated to a specific car. If one or more booths to which this destination call was not assigned now arrive earlier or simultaneously on the input floor, the destination call is also assigned to these booths. Since the passenger does not know the assigned cabin in this facility, he can reach the desired destination floor with this method in any case. According to a call allocation criterion of the device described above, if a car is present on one floor, a destination call entered on this floor is allocated to this car. When using this allocation criterion for the processing of peak traffic from a main stop, it must be expected that there will be more cabins in addition to the one cabin in the main stop, so that the destination calls entered must also be allocated to these cabins according to the control mode. The passengers will thus be divided into several cabins, so that efficient operation, which presupposes the maximum number of filled cabins, cannot be achieved. In addition, due to the multiple allocation, either empty trips of the unused cabins or an additional control effort to delete cabin calls that are no longer required must be accepted.

Es ist daher Aufgabe der Erfindung, eine Einrichtung der eingangs genannten Art zu schaffen, bei der die Zuteilung der Rufe auf der Haupthaltestelle während des Aufwärtsspitzenverkehrs derart erfolgt, dass die auf der Haupthaltestelle wartenden Fahrgäste auch bei grösseren Aufzugsanlagen und starkem Verkehrsanfall mühelos und schnell erkennen können, ob einer ankommenden bzw. einer abfahrtsbereit vorhandenen Kabine die von ihnen eingegebenen Rufe zugeteilt werden oder nicht.It is therefore an object of the invention to provide a device of the type mentioned at the outset, in which the calls are allocated to the main stop during upward peak traffic in such a way that the passengers waiting at the main stop can recognize effortlessly and quickly even with larger elevator systems and heavy traffic whether an incoming or ready-to-depart cabin is assigned the calls you entered or not.

Diese Aufgabe wird durch die im Patentanspruch 1 gekennzeichnete Erfindung gelöst. Hierbei ist eine Verriegelungsschaltung vorgesehen, die bewirkt, dass bei Anwesenheit mehrerer Kabinen auf der Haupthaltestelle immer nur die Türen eines Aufzuges geöffnet werden können, wobei diesem Aufzug die auf der Haupthaltestelle eingegebenen Rufe zugeteilt werden. Die Rufregistriereinrichtungen werden zu einem vom Beginn des Türschliessens abhängigen Zeitpunkt oder nach der Eingabe einer bestimmten Anzahl Rufe mittels einer Sperrschaltung gesperrt und bei der Abfahrt der betreffenden Kabine wieder freigegeben. Während der Sperrzeit wird ein in einem Anzeigefeld der Rufregistriereinrichtungen angeordnetes, die Sperrung signalisierendes Anzeigeelement aktiviert.This object is achieved by the invention characterized in claim 1. In this case, a locking circuit is provided, which ensures that only the doors of an elevator can be opened in the presence of several cabins at the main stop, the calls entered at the main stop being assigned to this elevator. The call registration devices are blocked at a point in time dependent on the start of the door closing or after the entry of a certain number of calls by means of a blocking circuit and released again when the relevant cabin departs. During the blocking time, a display element which signals the blocking and is arranged in a display field of the call registration devices is activated.

Die mit der Erfindung erzielten Vorteile liegen in der einfachen Art der Rufzuteilung, wobei Doppelzuteilungen vermieden werden und keine Rufe verloren gehen können. Ein weiterer Vorteil ist in dem die Sperrung der Rufregistriereinrichtungen anzeigenden Signal zu sehen. Hierdurch erhalten die im ungesperrten Zustand im Anzeigefeld erscheinenden Rufquittierungen eine erhöhte Aussagekraft, da den Fahrgästen damit angezeigt wird, dass die eingegebenen Rufe der nächsten ankommenden bzw. der abfahrtsbereit vorhandenen Kabine zugeteilt werden. Mit dem Erscheinen des Sperrsignales wird den Fahrgästen angezeigt, dass die Rufe nicht registriert werden und mit der Rufeingabe bis zum Verschwinden des Sperrsignales gewartet werden muss.The advantages achieved with the invention lie in the simple type of call allocation, double assignments being avoided and no calls being lost. Another advantage can be seen in the signal indicating the blocking of the call registration devices. As a result, the call acknowledgments that appear in the unlocked state on the display field are more meaningful, since it indicates to the passengers that the entered calls are assigned to the next arriving cabin or the cabin that is ready for departure. When the blocking signal appears, passengers are informed that the calls have not been registered and that the call must be entered before the blocking signal disappears.

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

  • Fig. 1 eine schematische Darstellung eines Aufzuges einer Aufzugsgruppe mit der erfindungsgemässen Einrichtung,
  • Fig. 2 eine Verriegelungs- und eine Sperrschaltung der Einrichtung gemäss Fig. 1 für die Haupthaltestelle einer aus drei Aufzügen bestehenden Aufzugsgruppe und
  • Fig. 3 eine Teilansicht einer Rufregistriereinrichtung.
The invention is explained in more detail below with reference to an exemplary embodiment shown in the drawing. Show it:
  • 1 is a schematic representation of an elevator of an elevator group with the device according to the invention,
  • Fig. 2 shows a locking and a blocking circuit of the device according to Fig. 1 for the main stop of an elevator group consisting of three elevators and
  • Fig. 3 is a partial view of a call registration device.

In der Fig. 1 ist mit 1 ein beispielsweise fünf Stockwerke E-1, E0, E1, E2 und E3 umfassender Teil des Schachtes eines Aufzuges a einer aus drei Aufzügen a, b, c bestehenden Aufzugsgruppe bezeichnet, in welchem eine über ein Förderseil 2 antreibbare Kabine 3 geführt ist. Die Stockwerkbezeichnung EO ist dem Erdgeschoss zugeordnet, das in nachfolgender Beschreibung auch Haupthaltestelle genannt wird. Auf den Stockwerken sind Rufregistriereinrichtungen 4 vorgesehen, weiche beispielsweise in Form einer 10er- Tastatur 51 (Fig. 3) angeordnete Rufknöpfe aufweisen, mittels welchen Rufe für Fahrten zu gewünschten Zielstockwerken eingegeben werden können. Hierbei wird bei der Eingabe eines Rufes ein das Zielstockwerk bezeichnender Kabinenruf und ein das Eingabestockwerk bezeichnender Stockwerkruf gespeichert. Die Rufregistriereinrichtungen 4 sind mit einer Gruppensteuerungseinrichtung verbunden, die aus den Aufzügen a, b, c zugeordneten Mikrocomputersystemen 5 besteht, wobei nur ein dem Aufzug a zugeordneter Teil dargestellt ist, der einen Stockwerkrufspeicher 6, einen Kabinenrufspeicher 7 und einen Selektor 8 umfasst. Wie bekannt, signalisiert der Selektor 8 jeweils dasjenige Stockwerk, auf dem die fahrende Kabine 3 bei Vorliegen eines Haltebefehls noch anhalten könnte. Entsprechend der üblichen symbolischen Logik sind die im Stockwerk- bzw. Kabinenrufspeicher 6, 7 gespeicherten Rufe mit logisch "1" gekennzeichnet. Die Gruppensteuerungseinrichtung, welche beispielsweise der mit dem EP 0 032 213 vorgeschlagenen Gruppensteuerungseinrichtung ähnlich ist, arbeitet bei Normalbetrieb in der Weise, dass neu eintreffende Rufe jeweils denjenigen Kabinen zugeteilt werden, die diese Rufe in kürzester Zeit bedienen können. Neben dem Normalbetriebsprogramm weist die Gruppensteuerungseinrichtung auch ein Steuerungsprogramm für den Aufwärtsspitzenverkehr auf, das in einer dem vorstehend beschriebenen Stand der Technik ähnlichen Weise abläuft. Während des Aufwärtsspitzenverkehrs werden beim Verteilverkehr in der Haupthaltestelle E0, wie nachstehend näher beschrieben, die dort eingegebenen Rufe der zuerst ankommenden bzw. bereits mit offenen Türen vorhandenen Kabine zugeteilt.In FIG. 1, 1 denotes, for example, a part of the shaft of an elevator a comprising an elevator group consisting of three elevators a, b, c and comprising five floors E-1, E0, E1, E2 and E3, in which one elevator elevator 2 drivable cabin 3 is guided. The floor designation EO is assigned to the ground floor, which is also called the main stop in the description below. Call registration devices 4 are provided on the floors, which have call buttons arranged, for example, in the form of a 10-key keyboard 51 (FIG. 3), by means of which calls for journeys to desired destination floors can be entered. In this case, when a call is entered, a cabin call denoting the destination floor and a floor call denoting the entry floor are stored. The call registration devices 4 are connected to a group control device which consists of the microcomputer systems 5 assigned to the elevators a, b, c, only one part being assigned to the elevator a being shown, which comprises a floor call memory 6, a car call memory 7 and a selector 8. As is known, the selector 8 signals the floor on which the moving cabin 3 could still stop if a stop command is present. In accordance with the usual symbolic logic, the calls stored in the floor or cabin call memory 6, 7 are identified with a logic "1". The group control device, which is similar, for example, to the group control device proposed by EP 0 032 213, operates in normal operation in such a way that newly arriving calls are allocated to those cabins that can service these calls in the shortest possible time. In addition to the normal operating program, the group control device also has a control program for the upward peak traffic, which runs in a manner similar to the prior art described above. During upward peak traffic, the calls entered in the main bus stop E0, as described in more detail below, are allocated to the cabin that arrives first or that already exists with open doors.

Wie bei Aufzügen mit automatischen Türen bekannt, weist die Kabine 3 einen Türantrieb 9 auf, mittels welchem die Kabinentür und mit dieser über ein nicht dargestelltes Mitnehmersystem verbindbare Schachttüren 10 betätigt werden können. Zum Zwecke der Steuerung ist der Türantrieb 9 mit dem Mikrocomputersystem 5 des betreffenden Aufzuges verbunden.As is known in the case of elevators with automatic doors, the cabin 3 has a door drive 9 by means of which the cabin door and shaft doors 10 which can be connected to it via a driver system (not shown) can be actuated. For the purpose of control, the door drive 9 is connected to the microcomputer system 5 of the elevator in question.

Gemäss Fig. 3 weist die Rufregistriereinrichtung 4 ein Anzeigefeld 50 auf, in welchem bei Eingabe von Rufen mittels der Rufknöpfe der 10er-Tastatur 51 die Rufquittierung in Form einer Dezimalzahl erscheint. Die Darstellung der Dezimalzahl kann hierbei beispielsweise durch eine Anzeigeelektronik in Form einer Siebensegmentanzeige mit Leuchtdioden erfolgen. Mit 52 ist ein weiteres, die Sperrung der Rufregistriereinrichtung 4 signalisierendes Anzeigeelement in Form eines XX-Zeichens bezeichnet, das ebenfalls durch Leuchtdioden gebildet wird und das mittels der Sperrschaltung 25 aktiviert werden kann und dabei rot aufleuchtet.According to FIG. 3, the call registration device 4 has a display field 50, in which the call acknowledgment appears in the form of a decimal number when calls are input using the call buttons on the 10-key keyboard 51. The decimal number can be represented, for example, by display electronics in the form of a seven-segment display with light-emitting diodes. 52 is another display element which signals the blocking of the call registration device 4 in the form of an XX symbol, which is likewise formed by light-emitting diodes and which can be activated by means of the blocking circuit 25 and lights up red in the process.

Die vorstehend beschriebene Einrichtung arbeitet wie folgt:

  • Bei Einschaltung des Steuerungsprogrammes für den Aufwärtsspitzenverkehr werden die Sperrschaltung 25 und die Verriegelungsschaltung 28 aktiviert und die Kabinen durch simulierte Stockwerkrufe zur Haupthaltestelle EO gerufen. Hierbei möge angenommen sein, dass die Kabine des Aufzuges a zuerst auf der Haupthaltestelle EO eintrifft und die Türen öffnet. Gemäss der beispielsweise gewählten Logik erzeugt hierbei der betreffende Türinformationsgeber 26 eine dem offenen Zustand zugeordnete Türinformation logisch "0", so dass den Mikrocomputersystemen 5 der Aufzüge b und c über die UND-Glieder 39, 41 und 40, 45 ein den Start des Türsteuerungsprogrammes verhindernde Verriegelungsinformation logisch "0" zugeführt wird und eine später eintreffende Kabine dieser Aufzüge die Türen nicht öffnet. Bei gleichzeitiger Einfahrt beispielsweise der Kabinen der Aufzüge a und b in die Haupthaltestelle EO werden kurz vor Beginn des Türöffnens die zugeordneten Schachtschalter betätigt, so dass am Ausgang des UND-Gliedes 42 logisch "1" und am Ausgang des UND-NICHT-Gliedes 46 logisch "0" erscheint. Damit wird die den Mikrocomputersystemen 5 der Aufzüge b und c über die UND-Glieder 41 und 45 zugeführte Verriegelungsinformation logisch "0". Da die Türinformationen bei geschlossenen Türen logisch "1" sind, wird dem Mikrocomputersystem 5 des Aufzuges a über das UND-Glied 38 eine Verriegelungsinformation logisch "1" zugeführt, so dass bei diesem Aufzug das Türsteuerungsprogramm gestartet werden kann.
The device described above works as follows:
  • When the control program for the upward peak traffic is switched on, the blocking circuit 25 and the locking circuit 28 are activated and the cabins are called to the main stop EO by simulated floor calls. It may be assumed here that the car of elevator a first arrives at the main stop EO and the Doors open. According to the logic selected, for example, the relevant door information transmitter 26 generates a door information associated with the open state, logically "0", so that the microcomputer systems 5 of the elevators b and c via the AND gates 39, 41 and 40, 45 prevent the door control program from starting Locking information is supplied logically "0" and a cabin arriving later does not open the doors. When, for example, the cabins of elevators a and b enter the main stop EO at the same time, the assigned shaft switches are actuated shortly before the door opens, so that logic "1" at the output of AND gate 42 and logic at the output of AND AND NOT gate 46 "0" appears. The locking information supplied to the microcomputer systems 5 of the elevators b and c via the AND gates 41 and 45 thus becomes logic "0". Since the door information is logic "1" when the doors are closed, locking information logic "1" is supplied to the microcomputer system 5 of the elevator a via the AND gate 38, so that the door control program can be started with this elevator.

Das Türsteuerungsprogramm sei nun derart, dass das Öffnen der Türen bereits kurz vor der Einfahrt in die Haupthaltestelle EO eingeleitet wird. Nachdem die Türen ganz geöffnet sind, werden sie eine bestimmte Zeit offengehalten, worauf sie automatisch geschlossen werden und die betreffende Kabine abfahren kann. Es sei nun angenommen, dass die von den Fahrgästen auf der Haupthaltestelle EO eingegebenen Rufe in den Anzeigefeldern 50 (Fig. 3) der Rufregistriereinrichtungen 4 quittiert wurden, was bedeutet, dass sie einer ankommenden bzw. bereits vorhandenen Kabine zugeteilt werden. Wie anfänglich beispielsweise angenommen, trifft die Kabine des Aufzuges a auf der Haupthaltestelle EO ein, wobei gemäss gewählter Logik das Selektorsignal, das Stopsignal und das Aufwärts- Weiterfahrtssignal logisch "1" sind. Da ausserdem die dem UND-Glied 21 zugeführten Türinformationen der Aufzüge b und c logisch "1" sind, wird über das UND-Glied 20, die UND-Glieder 13 und 16 des Signalisations-Schaltkreises 11 und den ersten Eingang e1 des Anzeigers 12 das erste Anzeigeelement aktiviert (Fig. 1). Hierbei leuchtet der Aufwärtspfeil des Anzeigers 12 des Aufzuges a grün auf, womit den wartenden Fahrgästen angezeigt wird, dass sie einsteigen dürfen, da die von ihnen eingegebenen und quittierten Rufe von diesem Aufzug bedient werden.The door control program is now such that the opening of the doors is initiated shortly before entering the main stop EO. After the doors are fully opened, they are kept open for a certain time, after which they are automatically closed and the relevant cabin can be driven down. It is now assumed that the calls entered by the passengers at the main stop EO have been acknowledged in the display fields 50 (FIG. 3) of the call registration devices 4, which means that they are allocated to an arriving or already existing cabin. As initially assumed, for example, the car of elevator a arrives at the main stop EO, the selector signal, the stop signal and the upward travel signal being logic "1" according to the logic selected. In addition, since the door information of the elevators b and c supplied to the AND gate 21 is logic "1", the AND gate 20, the AND gate 13 and 16 of the signaling circuit 11 and the first input e1 of the indicator 12 will first display element activated (Fig. 1). Here, the upward arrow of the indicator 12 of the elevator a lights up green, indicating to the waiting passengers that they are allowed to get in, since the calls they have entered and acknowledged are served by this elevator.

Damit einem Fahrgast, der seinen Ruf erst gegen Ende der Tür-Offenhaltezeit eingibt, noch genügend Zeit zum Einsteigen verbleibt, ist die Rufeingabe nur bis zu einem Zeitpunkt möglich, der vor dem Beginn des Tüschliessens liegt. Zu diesem Zeitpunkt wird vom Impulsgeber 27 der Schachttür 10 des Aufzuges a ein Impuls erzeugt, der über die ODER-Glieder 34 und 33 dem Seteingang S des RS-Flip-Flops 30 zugeführt wird. Mittels des daraufhin am Ausgang Q des RS-Flip-Flops 30 auftretenden Signales logisch "1" wird das die Sperrung der Rufregistriereinrichtungen 4 signalisierende XX-Zeichen 52 (Fig. 3) aktiviert, so dass es rot aufleuchtet. Gleichzeitig wird der Transistorschalter 31 in den offenen Zustand gesteuert, wodurch die Speisung der Rufknöpfe unterbrochen wird und keine Rufe mehr quittiert werden.So that a passenger who only enters his call at the end of the door hold-open time has enough time to get in, the call can only be entered up to a point in time before the start of the door closing. At this time, a pulse is generated by the pulse generator 27 of the shaft door 10 of the elevator a, which is fed via the OR gates 34 and 33 to the set input S of the RS flip-flop 30. By means of the logic "1" signal which then appears at the output Q of the RS flip-flop 30, the XX symbol 52 (FIG. 3) which signals the blocking of the call registration devices 4 is activated, so that it lights up red. At the same time the transistor switch 31 is controlled in the open state, whereby the supply of the call buttons is interrupted and no more calls are acknowledged.

Im Rahmen des Steuerungsprogrammes für den Aufwärtsspitzenverkehr werden nun die registrierten Rufe in den Kabinenrufspeicher 7 des Mikrocomputersystems 5 des Aufzuges a übertragen und danach in den Rufregistriereinrichtungen 4 gelöscht (Fig. 1).As part of the control program for the upward peak traffic, the registered calls are now transferred to the cabin call memory 7 of the microcomputer system 5 of the elevator a and then deleted in the call registration devices 4 (FIG. 1).

Nach dem Schliessen der Türen des Aufzuges a sind die Türinformationen aller Aufzüge logisch "1 so dass am Ausgang des UND-Gliedes 36 logisch "1" vorhanden ist. Da der zugeordnete Kabinenpositionsgeber 24 bis zur Abfahrt der Kabine des Aufzuges a logisch "1" signalisiert, ist der Ausgang des ODER-Gliedes 35 ebenfalls logisch "1 ", so dass am Ausgang des UND-Gliedes 37 ein kurzer Impuls entsteht und das RS-Flip-Flop 30 zurückgesetzt wird. Demzufolge wird dessen Ausgang Q logisch "0" und die Sperrung der Rufregistriereinrichtungen 4 wieder aufgehoben. Mit dem Wechsel der Türinformation des Aufzuges a nach logisch "1" werden die Verriegelungsinformationen an den Ausgängen der UND-Glieder 41 und 45 ebenfalls logisch "1", so dass das Mikrocomputersystem 5 des Aufzuges b das Türsteuerungsprogramm starten kann, da sich gemäss dem weiteren gewählten Beispiel die Kabine des Aufzuges b bereits in der Haupthaltestelle EO befindet.After the doors of elevator a have been closed, the door information of all elevators is logic "1" so that logic "1" is present at the output of AND gate 36. Since the assigned car position transmitter 24 signals logic "1" until the elevator car a leaves , the output of the OR gate 35 is also logic "1", so that a short pulse occurs at the output of the AND gate 37 and the RS flip-flop 30 is reset. As a result, its output Q becomes logic "0" and the Blocking of the call registration devices 4 is released again. With the change of the door information of the elevator a to logic "1", the locking information at the outputs of the AND gates 41 and 45 also becomes logic "1", so that the microcomputer system 5 of the elevator b starts the door control program can, since according to the further example chosen, the elevator car b is already in the main stop EO.

Es sei weiterhin angenommen, dass bereits vor dem vom Impulsgeber 27 bestimmten Zeitpunkt die Anzahl der eingegebenen Rufe der maximal zulässigen Anzahl Zusteiger entspricht. In diesem Fall tritt am Übertragsausgang o des Zählers 29 ein Signal logisch "1" auf, mittels welchem über das ODER-Glied 33 das RS-Flip-Flop 30 gesetzt und die vorstehend näher beschriebene Sperrung der Rufregistriereinrichtungen 4 ausgelöst wird. Wegen der Signallaufzeiten wird die Sperrung verzögert ausgelöst, so dass der Ruf des letzten Fahrgastes noch quittiert wird, ehe das die Sperrung signalisierende XX-Zeichen 52 im Anzeigefeld 50 erscheint (Fig. 3). Bei der vorstehend bereits beschriebenen Aufhebung der Sperrung der Rufregistriereinrichtungen 4 wird der am Ausgang des UND-Gliedes 37 auftretende Resetimpuls auch dem Zähler 29 zugeführt, so dass dieser zurückgestellt wird.It is further assumed that the number of calls entered corresponds to the maximum permitted number of boarders before the time determined by the pulse generator 27. In this case, a signal "1" occurs at the carry output o of the counter 29, by means of which the RS flip-flop 30 is set via the OR gate 33 and the blocking of the call registration devices 4 described in more detail above is triggered. Because of the signal propagation times, the blocking is triggered with a delay, so that the call of the last passenger is still acknowledged before the XX symbol 52 indicating the blocking appears in the display field 50 (FIG. 3). When the blocking of the call registration devices 4 has already been lifted, the reset pulse occurring at the output of the AND gate 37 is also fed to the counter 29, so that it is reset.

Gemäss einem weiteren Beispiel möge angenommen sein, dass sich die Kabine des Aufzuges b mit offenen Türen auf der Haupthaltestelle EO befindet und die Kabine des Aufzuges a mit einem Fahrgast eintrifft, der an der Haupthaltestelle EO aussteigen will. In diesem Fall ignoriert das Mikrocomputersystem 5 des Aufzuges a die Verriegelungsinformation logisch "0", so dass die Türen geöffnet und, nachdem der Fahrgast ausgestiegen ist, sofort wieder geschlossen werden. Bei Ankunft der Kabine des Aufzuges a sind das Selektorsignal, das Stopsignal und der Ausgang der der Haupthaltestelle EO zugeordneten Speicherzelle des Kabinenrufspeichers 7 logisch "1 Da ausserdem die dem UND-Glied 21 zugeführte Türinformation des Aufzuges b und damit der Ausgang des UND-Gliedes 20 logisch "0" sind, wird über das UND-Glied 14, das NICHT-Glied 18, das UND-Glied 15 und den dritten Eingang e3 des Anzeigers 12 das X-Zeichen aktiviert, das hierbei rot aufleuchtet (Fig. 1). Damit wird den auf der Haupthaltestelle EO wartenden Fahrgästen angezeigt, dass sie nicht in die Kabine des Aufzuges a einsteigen dürfen, da die von ihnen eingegebenen Rufe nicht dieser Kabine, sondern der früher eingetroffenen Kabine des Aufzuges b zugeteilt werden.According to a further example, it may be assumed that the car of elevator b is with open doors on the main stop EO and the car of elevator a arrives with a passenger who wants to get out at the main stop EO. In this case, the microcomputer system 5 of elevator a logically ignores the locking information "0", so that the doors are opened and are closed again immediately after the passenger has got out. When the car of elevator a arrives, the selector signal, the stop signal and the output of the memory cell of the car call memory 7 assigned to the main stop EO are logical "1" since the door information of the elevator b supplied to the AND gate 21 and thus the output of the AND gate 20 are also logical logical "0" are activated via the AND gate 14, the NOT gate 18, the AND gate 15 and the third input e3 of the indicator 12, which lights up red (Fig. 1). This indicates to the passengers waiting at the main stop EO that they must not enter the elevator a car, since the calls they enter are not assigned to this cabin, but to the elevator b cabin that arrived earlier.
