  • US-A-3 493 922 discloses a call registration and display device which is arranged in an elevator car and which has a 10-key keyboard for entering car calls and a display field for displaying the selected floor. So that the entered call can be saved and transferred to the control, an additional registration key must be pressed within a predetermined time. If the registration key is not actuated, it lights up after the predetermined time has elapsed, the call entered being automatically deleted after a further predetermined time if this signal is ignored. Another call can also be used to delete a call if it has been entered incorrectly or in error, for example. As can be seen from the above, the call entry with this call registration device requires increased attention of the passenger and especially also in the case of incorrectly entered calls or carelessness, an increased expenditure of time per entered call, so that with several, simultaneously boarding passengers may experience uncomfortable situations due to disabilities.
  • call registration devices are provided which likewise have a 10-key keyboard.
  • the call registration devices are arranged on the floors, whereas no call buttons are provided in the elevator cars.
  • the call registration device has, instead of the registration button provided in the first-mentioned prior art, a time limit circuit which is activated when a first digit is entered and which requires the second digit of a call to be within a predetermined one Time must be entered, whereby the entered call is automatically registered after this time. Failure to observe the time limit can result in incorrect call entries.
  • the group control mentioned above has a computer in the form of a microprocessor and a comparison device for each elevator. Immediately after registering a call, the computer calculates a sum corresponding to the average waiting time of all passengers, also called service costs, from elevator-specific data. During an immediately following comparison of the operating costs of all elevators, the elevator with the lowest operating costs is determined, to which the relevant call is then allocated. Since when entering a call on a floor, in addition to a floor call, a cabin call that identifies the desired destination floor is also saved, the latter can be used when calculating the service costs are taken into account, so that the cabin determined in the comparison is the cheapest for both the operation of the input floor and that of the destination floor.
  • This method means that the passengers waiting on a floor can only be informed of the assigned cabin shortly before arrival, for example by lighting up a direction indicator arranged above the elevator door in question and, if appropriate, by an acoustic signal.

Abstract

With this call-registering keyboard and display device, calls for desired floors can be input without a registering key having to be pressed after a correct input or without a correction key having to be pressed after an incorrect input. Here, a call input is only possible when a proximity switch (28) connected to the keyboard (20) is activated. Upon deactivation of the proximity switch (28), a delay circuit (31) causes the call to be automatically registered. An incorrectly input call is automatically cancelled by means of a second control circuit (61), in which case a second display element (60) in the form of a double question mark lights up at the same time. A third display element arranged in the same display field and signalling the selected lift as well as a fourth and fifth display element signalling the position of the selected lift relative to the actuated keyboard (20) are connected to a group control device via further control circuits. During the call assignment the third and the relevant fourth or fifth display elements are activated, which then light up together with a first display element signalling the selected floor and already activated during the call input. <IMAGE>

Description

Die Erfindung betrifft auf den Stockwerken angeordnete Rufregistrier- und Anzeigeeinrichtungen für Aufzüge mit Sofortzuteilung von Zielrufen, wobei jede Rufregistrier- und Anzeigeeinrichtung eine Tastatur für die Eingabe von Rufen für gewünschte Zielstockwerke, Rufspeicher und ein Anzeigefeld aufweist, in welchem mindestens ein erstes, das gewählte Zielstockwerk signalisierendes Anzeigeelement angeordnet ist, und wobei eine erste, mit der Tastatur und dem ersten Anzeigeelement verbundene Steuerschaltung vorgesehen ist, mittels welcher das erste Anzeigeelement bei der Rufeingabe aktiviert werden kann.The invention relates to call registering and display devices for elevators arranged on the floors with immediate assignment of destination calls, each call registration and display device having a keyboard for entering calls for desired destination floors, call memory and a display field in which at least a first, the selected destination floor signaling display element is arranged, and wherein a first control circuit connected to the keyboard and the first display element is provided, by means of which the first display element can be activated when the call is input.

Mit der US-A- 3 493 922 ist eine in einer Aufzugskabine angeordnete Rufregistrier- und Anzeigeeinrichtung bekannt geworden, welche eine 10er-Tastatur für die Eingabe von Kabinenrufen und ein Anzeigefeld für die Anzeige des gewählten Stockwerkes aufweisen. Damit der eingegebene Ruf gespeichert und der Steuerung übergeben werden kann, muss eine zusätzliche Registriertaste innerhalb einer vorbestimmten Zeit betätigt werden. Wird die Registriertaste nicht betätigt, so leuchtet sie nach Ablauf der vorbestimmten Zeit auf, wobei der eingegebene Ruf bei Nichtbeachtung dieses Signals nach einer weiteren vorbestimmten Zeit automatisch gelöscht wird. Mittels einer weiteren zusätzlichen Taste kann ein Ruf ebenfalls gelöscht werden, wenn er beispielsweise fehlerhaft oder irrtümlich eingegeben wurde. Wie aus Vorstehendem ersichtlich, erfordert die Rufeingabe bei dieser Rufregistriereinrichtung erhöhte Aufmerksamkeit des Fahrgastes und vor allem auch bei fehlerhaft eingegebenen Rufen oder Unachtsamkeit einen erhöhten Zeitaufwand pro eingegebenen Ruf, so dass bei mehreren, gleichzeitig einsteigenden Fahrgästen unangenehme Situationen durch Behinderungen entstehen können.US-A-3 493 922 discloses a call registration and display device which is arranged in an elevator car and which has a 10-key keyboard for entering car calls and a display field for displaying the selected floor.

If the registration key is not actuated, it lights up after the predetermined time has elapsed, the call entered being automatically deleted after a further predetermined time if this signal is ignored. Another call can also be used to delete a call if it has been entered incorrectly or in error, for example. As can be seen from the above, the call entry with this call registration device requires increased attention of the passenger and especially also in the case of incorrectly entered calls or carelessness, an increased expenditure of time per entered call, so that with several, simultaneously boarding passengers may experience uncomfortable situations due to disabilities.

Um den Rufeingabe-Vorgang zu vereinfachen und zu beschleunigen, weist die Rufregistriereinrichtung anstelle der im zuerst genannten Stand der Technik vorgesehenen Registriertaste eine Zeitbegrenzungsschaltung auf, die bei der Eingabe einer ersten Ziffer aktiviert wird und welche bedingt, dass die zweite Ziffer eines Rufes innerhalb einer vorbestimmten Zeit eingegeben werden muss, wobei der eingegebene Ruf nach Ablauf dieser Zeit automatisch registriert wird. Bei Nichtbeachtung der Zeitbegrenzung kann es hierbei jedoch zu fehlerhaften Rufeingaben kommen.In a group control for elevators which has become known from EP-A-0 246 395, call registration devices are provided which likewise have a 10-key keyboard.

By means of these call registration devices, calls for desired target floors can be entered, a call characterizing the input floor being stored in the floor call memories and the calls characterizing the target floors being stored in the cabin call memories of the elevators. In order to simplify and accelerate the call entry process, the call registration device has, instead of the registration button provided in the first-mentioned prior art, a time limit circuit which is activated when a first digit is entered and which requires the second digit of a call to be within a predetermined one Time must be entered, whereby the entered call is automatically registered after this time. Failure to observe the time limit can result in incorrect call entries.

Die vorstehend erwähnte Gruppensteuerung weist je Aufzug einen Rechner in Form eines Mikroprozessors und eine Vergleichseinrichtung auf. Der Rechner errechnet unmittelbar nach der Registrierung eines Rufes aus aufzugsspezifischen Daten eine der durchschnittlichen Wartezeit aller Fahrgäste entsprechende Summe, auch Bedienungskosten genannt. Während eines sofort darauffolgenden Vergleiches der Bedienungskosten aller Aufzüge wird der Aufzug mit den kleinsten Bedienungskosten ermittelt, welchem dann der betreffende Ruf zugeteilt wird. Da bei der Rufeingabe auf einem Stockwerk ausser einem Stockwerkruf auch ein das gewünschte Zielstockwerk kennzeichnender Kabinenruf gespeichert wird, kann letzterer bei der Berechnung der Bedienungskosten mit berücksichtigt werden, so dass die beim Vergleich ermittelte Kabine sowohl für die Bedienung des Eingabestockwerkes als auch für die des Zielstockwerkes die günstigste ist.The group control mentioned above has a computer in the form of a microprocessor and a comparison device for each elevator. Immediately after registering a call, the computer calculates a sum corresponding to the average waiting time of all passengers, also called service costs, from elevator-specific data. During an immediately following comparison of the operating costs of all elevators, the elevator with the lowest operating costs is determined, to which the relevant call is then allocated. Since when entering a call on a floor, in addition to a floor call, a cabin call that identifies the desired destination floor is also saved, the latter can be used when calculating the service costs are taken into account, so that the cabin determined in the comparison is the cheapest for both the operation of the input floor and that of the destination floor.

Bei Gruppensteuerungen, bei denen in herkömmlicher Weise die Stockwerk- und Kabinenrufe mittels auf den Stockwerken bzw. in der Kabine angeordneten Rufknöpfen eingegeben werden, muss ein Fahrgast, um zu einem Ziel zu gelangen, zweimal wählen. Die Steuerungseinrichtung erfährt daher das gewünschte Fahrziel relativ spät, das somit für die Zuteilung des betreffenden Stockwerkrufes nicht berücksichtigt werden kann. Die im Zuteilungsverfahren ermittelte Kabine ist daher die günstigste für den betreffenden Stockwerkruf, jedoch im allgemeinen nicht für das im Zeitpunkt der Berechnung unbekannte Fahrziel. Um trotzdem bessere Resultate zu erzielen, wird die Berechnung und Zuteilung eines Stockwerkrufes, wie beispielsweise bei der EP-B 0 032 213, bis zu einem Zeitpunkt verschoben, zu welchem die Übergabe an die Antriebssteuerung zwecks Einleitung der Verzögerung für den Halt am betreffenden Stockwerk erfolgen muss. Dieses Verfahren bedingt, dass den auf einem Stockwerk wartenden Fahrgästen die zugeteilte Kabine erst kurz vor der Ankunft, beispielsweise durch Aufleuchten eines über der betreffenden Aufzugstür angeordneten Richtungsanzeigers und gegebenenfalls durch ein akustisches Signal, bekanntgegeben werden kann. Bei grösseren Anlagen mit mehreren Aufzügen können hierbei für die Fahrgäste Schwierigkeiten entstehen, da relativ wenig Zeit verbleibt die Anzeige zu erkennen und sich rechtzeitig zum signalisierten Aufzug zu begeben.In group controls, in which the floor and cabin calls are entered in the conventional manner by means of call buttons arranged on the floors or in the cabin, a passenger must dial twice in order to arrive at a destination. The control device therefore finds out the desired destination relatively late, which therefore cannot be taken into account for the allocation of the floor call in question. The cabin determined in the allocation process is therefore the cheapest for the floor call in question, but generally not for the destination unknown at the time of the calculation. In order to nevertheless achieve better results, the calculation and allocation of a floor call, as for example in EP-B 0 032 213, is postponed until a time at which the transfer to the drive control takes place in order to initiate the delay for the stop on the floor in question got to. This method means that the passengers waiting on a floor can only be informed of the assigned cabin shortly before arrival, for example by lighting up a direction indicator arranged above the elevator door in question and, if appropriate, by an acoustic signal. In larger systems with several elevators, difficulties can arise for the passengers, since there is relatively little time to recognize the display and to go to the signaled elevator in good time.

Der Erfindung liegt die Aufgabe zugrunde eine Rufregistrier- und Anzeigeeinrichtung gemäss Oberbegriff zu schaffen, bei welcher einerseits die Rufeingabe nicht an vorgegebene Zeiten gebunden ist sowie fehlerhafte Eingaben besser erkannt und beseitigt werden können, und bei welcher andererseits die unmittelbar nach der Rufeingabe ausgewählte Kabine dem Fahrgast sofort und augenfällig zur Anzeige gebracht werden kann.The invention has for its object to provide a call registration and display device according to the preamble, in which on the one hand the call input is not tied to predetermined times and incorrect entries can be better recognized and eliminated, and on the other hand, the cabin selected immediately after the call input to the passenger immediately and clearly for display can be brought.

Diese Aufgabe wird durch die im Patentanspruch 1 gekennzeichnete Erfindung gelöst. Hierbei ist eine Rufeingabe erst dann möglich, wenn ein mit der Tastatur verbundener Näherungsschalter aktiviert wird. Bei der Entaktivierung des Näherungsschalters bewirkt eine Verzögerungsschaltung, dass der eingegebene Ruf automatisch registriert wird. Ein in einem Anzeigefeld angeordnetes zweites, eine fehlerhafte Eingabe signalisierendes Anzeigeelement wird mittels einer zweiten Steuerschaltung aktiviert, welche gleichzeitig die automatische Löschung der Fehleingabe bewirkt. Ein im gleichen Anzeigefeld angeordnetes drittes, den ausgewählten Aufzug signalisierendes Anzeigeelement sowie ein viertes und fünftes, die Lage des ausgewählten Aufzuges relativ zur betätigten Tastatur signalisierendes Anzeigelement stehen über weitere Steuerschaltungen mit einer Gruppensteuerungseinrichtung in Verbindung. Bei der Rufzuteilung werden das dritte und das betreffende vierte oder fünfte Anzeigeelement aktiviert, die dann zusammen mit einem ersten, das gewählte Zielstockwerk signalisierenden und bereits bei der Rufeingabe aktivierten Anzeigeelement aufleuchten.This object is achieved by the invention characterized in claim 1. Call entry is only possible when a proximity switch connected to the keyboard is activated. When the proximity switch is deactivated, a delay circuit causes the entered call to be registered automatically. A second display element, which indicates an incorrect input and is arranged in a display field, is activated by means of a second control circuit which at the same time effects the automatic deletion of the incorrect input. A third display element, which signals the selected elevator, and a fourth and fifth display element, which signals the position of the selected elevator relative to the actuated keyboard, are connected to a group control device via further control circuits. When the call is allocated, the third and the relevant fourth or fifth display element are activated, which then light up together with a first display element which signals the selected destination floor and is already activated when the call is input.

Die mit der Erfindung erzielten Vorteile liegen darin, dass nach der Rufeingabe weder eine Registriertaste, noch eine Korrekturtaste gedrückt werden muss, so dass Zeit gespart werden kann und der Eingabevorgang für den Fahrgast vereinfacht wird. Durch den Wegfall der vorbestimmten Eingabezeit wird eine bessere Anpassung an den Fahrgast erzielt und die Registrierung von fehlerhaft eingegebenen Rufen vermieden. Die erzielten Vorteile bezüglich der Anzeige sind darin zu sehen, dass bei Eingabe eines nicht vorhandenen Stockwerkes nicht die entsprechende Nummer, sondern ein den Fahrgast eindrücklicher auf die Fehleingabe hinweisendes Symbol signalisiert wird. Durch die Anordnung der den ausgewählten Aufzug und dessen Lage signalisierenden Anzeigeelemente im Anzeigefeld der Registriereinrichtung, muss der Fahrgast die unmittelbar nach der Rufeingabe aufleuchtenden betreffenden Symbole zwangsläufig wahrnehmen, so dass er sich rechtzeitig zum ausgewählten Aufzug begeben kann.The advantages achieved by the invention are that after the call has been entered neither a registration key nor a correction key has to be pressed, so that time can be saved and the input process for the passenger is simplified. By eliminating the predetermined input time, a better adaptation to the passenger is achieved and the registration of incorrectly entered calls is avoided. The advantages achieved with regard to the display can be seen in the fact that when a floor that is not present is entered, it is not the corresponding number that is signaled, but rather a symbol that more clearly indicates to the passenger that the entry was incorrect. By arranging the signaling of the selected elevator and its location Display elements in the display field of the registration device, the passenger must inevitably perceive the relevant symbols which light up immediately after the call is input, so that he can go to the selected elevator in good time.

Gemäss Fig. 1 besteht die beispielsweise für ein- und zweistellige Rufe konzipierte Rufregistrier- und Anzeigeeinrichtung aus einer Tastatur 20, welche zehn Tasten 1...9 und 0 für die Rufeingabe zu gewünschten Zielstockwerken aufweist. Die Tasten sind an ersten Eingängen von ersten UND-Gliedern 21.1....21.9, 21.0 angeschlossen, deren Ausgänge mit Set-Eingängen S von Tastenspeichern 23.1....23.9, 23.0 für die Speicherung einer zuerst eingegebenen Ziffer verbunden sind. Die Tasten sind ferner mit ersten Eingängen von zweiten UND-Gliedern 22.1....22.9, 22.0 verbunden, deren Ausgänge mit Set-Eingängen S von Tastenspeichern 24.1....24.9, 24.0 für die Speicherung einer zweiten eingegebenen Ziffer in Verbindung stehen.

Die Ausgänge Q aller Tastenspeicher sind mit den Eingängen einer kombinatorischen Logik 25 verbunden, deren Ausgänge an ersten Eingängen von dritten UND-Gliedern 26.0, 26.1....26.n angeschlossen sind, die ausgangsseitig mit Set-Eingängen S von den Stockwerken zugeordneten Rufspeichern 27.0, 27.1....27.n, in Form von beispielsweise RS-Flip-Flops, in Verbindung stehen. Die kombinatorische Logik 25 arbeitet derart, dass bei Eingabe eines einstelligen Rufes einer der den Stockwerken eintelliger Nummer zugeordneten Rufspeicher 27.0, 27.1....27.9, und bei Eingabe eines zweistelligen Rufes einer der den Stockwerken zweistelliger Nummer zugeordneten Rufspeicher 27.10....27.n gesetzt wird. Wenn beispielsweise Rufe für die Stockwerke 1 und 13 eingegeben werden, so muss die kombinatorische Logik 25 die Gleichungen

erfüllen, wobei die Eingangsvariablen 1', 2', 3'..... die erste eingegebene Ziffer und 1", 2", 3"..... die zweite eingegebene Ziffer bedeuten, und die Ausgangsvariablen 1, 13 die gewählten Zielstockwerke bedeuten. Die Abtastung der Rufspeicher 27.0, 27.1....27.n und die Übertragung der Rufe in eine Gruppensteuerungseinrichtung (Fig. 3) erfolgt in gleicher Weise wie bei einer mit der EP-A 0 246 395 bekannt gewordenen Rufregistriereinrichtung.1, the call registration and display device, which is designed, for example, for one- and two-digit calls, consists of a keyboard 20 which has ten keys 1... 9 and 0 for the call input to desired destination floors.

The combinatorial logic 25 works in such a way that when a single-digit call is entered, a call memory 27.0, 27.1 ... 27.9 assigned to the one-digit number of the floors, and when a two-digit call is entered, a call memory 27.10 ... 27 assigned to the two-digit number assigned to the floors .n is set. For example, if calls are entered for floors 1 and 13, combinatorial logic 25 needs the equations

Die vorstehend anhand der Fig. 1 beschriebene Rufregistrier-und Anzeigeeinrichtung arbeitet wie folgt:The call registration and display device described above with reference to FIG. 1 operates as follows:

Bei Annäherung der Hand eines Fahrgastes an die Tastatur 20 möge der Näherungsschalter 28 für die Dauer der Annäherung ein Signal logisch "1" erzeugen (Zeitpunkt I, Fig. 2a). Da vorerst angenommen wird, dass die übrigen Eingänge des vierten UND-Gliedes 29 ebenfalls "1" sind, werden die einen Eingänge des fünften, sechsten und siebten UND-Giedes 30.1, 30.2, 30.3 auf "1" gesetzt. Bei nicht gesetztem RS-Flip-Flop 45 weist dessen einer Ausgang Q den Zustand "1" auf, so dass die ersten UND-Glieder 21.1....21.9, 21.0 für die Rufeingabe freigegeben werden. Bei Eingabe eines Rufes für beispielsweise Stockwerk 13 wird vorerst die Taste der Ziffer 1 betätigt, wobei ein kurzer Impuls erzeugt und der Tastenspeicher 23.1 über das erste UND-Glied 21.1 gesetzt wird. Nach einer durch das weitere Verzögerungsglied 44 bedingten Verzögerung wird das RS-Flip-Flop 45 gesetzt, so dass dessen anderer Ausgang Q den Zustand "1" aufweist (Zeitpunkt II, Fig. 2a). Damit werden die zweiten UND-Glieder 22.1....22.9, 22.0 freigegeben und die ersten UND-Glieder 21.1....21.9, 21.0 gesperrt, so dass bei Betätigung der Taste der Ziffer 3 der zugeordnete Tastenspeicher 24.3 über das zweite UND-Glied 22.3 gesetzt wird. Die kombinatorische Logik 25 weist damit die Eingangsvariablen 1′ und 3˝ und die dem Rufspeicher 27.13 für Stockwerk 13 zugeordnete Ausgangsvariable 13 auf. Da bei der Eingabe der Ziffer 1 vorerst nur die ersten Tristate-Buffer 57 aktiviert sein mögen, wird die rechts angeordnete Siebensegmentanzeige 51 entsprechend aufleuchten. Bei Eingabe der Ziffer 3 und Eintreffen eines Signales "1" vom Datenausgang Z der zweiten Stufe des Zählers 66 werden die ersten Tristate-Buffer 57 entaktiviert, die zweiten und dritten 58, 59 hingegen aktiviert, so dass nun die links angeordnete zweite Siebensegmentanzeige 52 die Ziffer 1 und die rechts angeordnete erste Siebensegmentanzeige 51 die Ziffer 3 anzeigt. Entfernt der Fahrgast seine Hand von der Tastatur 20, so wird durch die abfallenden Flanken der Ausgangssignale des Näherungsschalters 28 und des ersten Verzögerungsgliedes 32 am Ausgang des ersten UND-Gliedes 37 der Verzögerungsschaltung 31 ein erster Impuls erzeugt, mittels welchem die dritten UND-Glieder 26.0, 26.1....26.n freigegeben werden und der dem Stockwerk 13 zugeordnete Rufspeicher 27.13 gesetzt wird (Zeitpunkt III, Fig. 2a). Gleichzeitig werden der Zähler 66 und das RS-Flip-Flop 45 zurückgesetzt sowie das Monoflop 34 geschaltet. Während der beispielsweise zwei Sekunden betragenden Einschaltzeit des Monoflops 34 ist keine Rufeingabe möglich, da das vierte UND-Glied 29 über das weitere NICHT-Glied 41 gesperrt ist. Durch die abfallenden Flanken der Ausgangssignale des Monoflops 34 und des zweiten Verzögerungsgliedes 33 wird am Ausgang des zweiten UND-Gliedes 38 der Verzögerungsschaltung 31 ein zweiter Impuls erzeugt, mittels welchem alle Tastenspeicher 23, 24 zurückgesetzt werden, wobei die Anzeige des eingegebenen Rufes verlöscht und die Sperrung der Rufeingabe wieder freigegeben wird (Zeitpunkt IV, Fig. 2a).When a passenger's hand approaches the keyboard 20, the proximity switch 28 may generate a logic "1" signal for the duration of the approach (time I, FIG. 2a). Since it is initially assumed that the remaining inputs of the fourth AND gate 29 are also "1", the one inputs of the fifth, sixth and seventh AND gate 30.1, 30.2, 30.3 set to "1". If the RS flip-flop 45 is not set, one of its outputs has an output Q state "1" so that the first AND gates 21.1 ... 21.9, 21.0 are released for call input. When a call is entered for, for example, floor 13, the key of number 1 is actuated initially, a short pulse being generated and the key memory 23.1 being set via the first AND gate 21.1. After a delay caused by the further delay element 44, the RS flip-flop 45 is set, so that its other output Q has the state "1" (time II, FIG. 2a). The second AND gates 22.1 .... 22.9, 22.0 are thus released and the first AND gates 21.1 .... 21.9, 21.0 are blocked, so that when the key of the number 3 is pressed, the assigned key memory 24.3 via the second AND Section 22.3 is set. The combinatorial logic 25 thus has the input variables 1 'and 3' and the output variable 13 assigned to the call memory 27.13 for floor 13. Since only the first tristate buffers 57 may initially be activated when the number 1 is entered, the seven-segment display 51 arranged on the right will light up accordingly. When the number 3 is entered and a signal "1" arrives from the data output Z of the second stage of the counter 66, the first tristate buffers 57 are deactivated, the second and third 58, 59 are activated, so that the second seven-segment display 52 arranged on the left now Number 1 and the first seven-segment display 51 arranged on the right shows the number 3. If the passenger removes his hand from the keyboard 20, the falling edges of the output signals of the proximity switch 28 and the first delay element 32 at the output of the first AND element 37 of the delay circuit 31 generate a first pulse, by means of which the third AND elements 26.0 , 26.1 .... 26.n are released and the call memory 27.13 assigned to the floor 13 is set (time III, FIG. 2a). At the same time, the counter 66 and the RS flip-flop 45 are reset and the monoflop 34 is switched. During the on time of the, for example, two seconds Call input is not possible for monoflops 34, since the fourth AND gate 29 is blocked by the further NOT gate 41. Due to the falling edges of the output signals of the monoflop 34 and the second delay element 33, a second pulse is generated at the output of the second AND element 38 of the delay circuit 31, by means of which all the key memories 23, 24 are reset, the display of the entered call being deleted and the Blocking the call input is released again (time IV, Fig. 2a).

Es sei nun angenommen, dass ein Fahrgast nach der Eingabe einer zweistelligen Zahl, ohne vorher seine Hand von der Tastatur 20 zu entfernen, eine weitere Taste betätigt. In diesem Fall erscheint am Übertragsausgang C des Zählers 55 ein Signal "1", so dass die Tastenspeicher 23, 24 zurückgesetzt werden und die Anzeige des Rufes gelöscht wird. Gleichzeitig wird das Monoflop 67 der zweiten Steuerschaltung 61 geschaltet, wodurch das zweite Anzeigeelement 60 aktiviert und die fehlerhafte Rufeingabe signalisiert wird (Zeitpunkt V, Fig. 2b). Ausserdem wird über die Glieder 65, 29, 30.1, 30.2, 30.3 eine erneute Rufeingabe gesperrt. Nach einer durch die Laufzeit des Übertragssignales bedingten Verzögerung, wird wie vorstehend bereits beschrieben, am Ausgang des UND-Gliedes 37 ein erster Impuls erzeugt, mittels welchem das RS-Flip-Flop 45 und der Zähler 66 zurückgesetzt werden, wobei das Übertragssignal verschwindet (Zeitpunkt VI, Fig. 2b). Durch die gesperrten UND-Glieder 39, 40 wird hierbei verhindert, dass das Monoflop 34 der Verzögerungsschaltung 31 und die Rufspeicher 27 geschaltet bzw. gesetzt werden können. Nach einer beispielsweise eine halbe Sekunde betragenden Einschaltzeit des Monoflops 67 verlöscht das zweite Anzeigeelement 60, wobei die Rufeingabe wieder freigegeben wird (Zeitpunkt VII, Fig. 2b).It is now assumed that a passenger presses another key after entering a two-digit number without first removing his hand from the keyboard 20. In this case, a signal "1" appears at the carry output C of the counter 55, so that the key memories 23, 24 are reset and the display of the call is deleted. At the same time, the monoflop 67 of the second control circuit 61 is switched, as a result of which the second display element 60 is activated and the incorrect call input is signaled (time V, FIG. 2b). In addition, a new call entry is blocked via links 65, 29, 30.1, 30.2, 30.3. After a delay caused by the transit time of the carry signal, a first pulse is generated at the output of the AND gate 37, as already described above, by means of which the RS flip-flop 45 and the counter 66 are reset, the carry signal disappearing (time VI, Fig. 2b). The blocked AND gates 39, 40 prevent the monoflop 34 of the delay circuit 31 and the call memory 27 from being switched or set. After a turn-on time of the monoflop 67, which is, for example, half a second, the second display element 60 is extinguished, the call input being released again (time VII, FIG. 2b).

Bei der Eingabe einer zweistelligen Zahl für ein nicht vorhandenes Stockwerk bleibt der Ausgang des NOR-Gliedes 46 im Zustand "1", da die kombinatorische Logik 25 für nicht vorhandene Stockwerke keine Ausgänge aufweist. Gleichzeitig erscheint am Datenausgang Z der zweiten Stufe des Zählers 66 ein Signal "1", so dass das Monoflop 67 geschaltet wird, wobei die gleichen Vorgänge wie vorstehend beschrieben ablaufen (Zeitpunkt V, VI, VII, Fig. 2b). Die irrtümliche Eingabe einer ein- oder zweistelligen Zahl eines vorhandenen Stockwerkes kann der Fahrgast durch Betätigen von einer bzw. zwei beliebigen Tasten rückgängig machen, wobei ebenfalls die vorstehend geschilderten Vorgänge ablaufen.When a two-digit number is entered for a floor that does not exist, the output of the NOR gate 46 remains in the "1" state, since the combinatorial logic 25 is not existing floors have no exits. At the same time, a signal "1" appears at the data output Z of the second stage of the counter 66, so that the monoflop 67 is switched, the same processes as described above taking place (time V, VI, VII, FIG. 2b). The passenger can undo the erroneous entry of a one- or two-digit number of an existing floor by pressing one or two arbitrary buttons, the processes described above also taking place.

In den Fig. 4-6 sind mit 80, 81, 82 ein drittes, viertes und fünftes Anzeigeelement bezeichnet, welche in einem Anzeigefeld 83 der Rufregistrier- und Anzeigeeinrichtung angeordnet sind. Die Anzeigeelemente 80, 81, 82 bestehen aus in einem Raster angeordneten Leuchtdioden, mittels welchen bei der Aktivierung beim dritten Anzeigeelement 80 die Buchstaben A, B, C gebildet werden können. Beim vierten Anzeigeelement 81 kann ein nach links gerichteter, beim fünften Anzeigeelement 82 ein nach rechts gerichteter Pfeil gebildet werden. Die Leuchtdioden des zweiten Anzeigeelementes 60 (Fig. 6) sind vorzugsweise zwischen den Leuchtdioden des ersten Anzeigeelementes 50 (Fig. 4, 5) plaziert. Entsprechend den drei Buchstaben A, B, C weist das dritte Anzeigeelement 80 drei Aktivierungsanschlüsse auf, die mit den Ausgängen der betreffenden, den Aufzügen A, B, C zugeordneten UND-Glieder 76 bzw. 78 verbunden sind. Bei der einen Rufregistrier- und Anzeigeeinrichtung AB ist das vierte Anzeigeelement 81 am Ausgang des dem Aufzug A zugeordneten UND-Gliedes 76, und das fünfte Anzeigeelement 82 über das ODER-Glied 77 an den Ausgängen der den Aufzügen B, C zugeordneten UND-Glieder 76 angeschlossen.

The display elements 80, 81, 82 consist of light-emitting diodes arranged in a grid, by means of which the letters A, B, C can be formed when the third display element 80 is activated. An arrow pointing to the left can be formed in the fourth display element 81 and an arrow pointing in the right direction in the fifth display element 82.

Die vorstehend anhand der Fig. 3-6 beschriebene Rufregistrier- und Anzeigeeinrichtung arbeitet wie folgt:The call registration and display device described above with reference to FIGS. 3-6 works as follows:

Es sei angenommen, dass ein Fahrgast beispielsweise auf dem Stockwerk 15 mittels der einen Rufregistrier- und Anzeigeeinrichtung AB einen Ruf für Stockwerk 24 eingibt. Hierbei leuchtet, wie anhand der Fig. 1, 2a, 2b beschrieben, das erste Anzeigeelement 50 entsprechend auf. Nachdem der Fahrgast seine Hand von der Tastatur 20 entfernt hat, wird der Ruf, wie in der bereits zitierten EP-A- 0 246 395 beschrieben, der Gruppensteuerung zugeführt und sofort derjenige Aufzug ermittelt, der den Ruf am besten bedienen kann. Es sei nun weiterhin angenommen, dass der Ruf dem Aufzug A zugeteilt wurde, wobei die Zuteilung endgültig sein möge. Wie aus vorgenannter Druckschrift und der EP-B 0 050 304 bekannt, läuft hierbei im Mikrocomputersystem 73a ein Programm ab, mittels welchem eine den Ruf betreffende Zuteilungsanweisung in einen Zuteilungsspeicher eingeschrieben wird. Am Ende des Programmes setzt das Mikrocomputersystem 73a die Adresse des Stockwerkes 15 auf den Adressenbus ab und gibt über die Baustein-Freigabeleitung ce die Adressendekodierer 74 des Aufzuges A frei. Der Ausgang des betreffenden Adressendekodierers 74 wird daher "1", so dass das zugeordnete Monoflop 75 geschaltet wird. Da bei eingeschaltetem Monoflop 34 (Fig. 1) der betätigten Rufregistrier- und Anzeigeeinrichtung AB die UND-Glieder 76 freigegeben sind, weist der Ausgang des dem Aufzug A zugeordneten UND-Gliedes 76 den Zustand "1" auf, so dass der Buchstabe A des dritten Anzeigeelementes 80 und das vierte Anzeigeelement 81 aktiviert werden. Damit werden dem Fahrgast unmittelbar nach der Eingabe des Rufes der zugeteilte Aufzug und dessen Lage in bezug auf die betätigte Rufregistrier- und Anzeigeeinrichtung zur Anzeige gebracht (Fig. 4). Nach einer Einschaltdauer des Monoflops 75 von beispielsweise zwei Sekunden verlöschen das dritte und vierte Anzeigeelement 80, 81 gleichzeitig mit dem ersten, die eingegebene Stockwerknummer signalisierenden Anzeigeelement 50. Wenn der Ruf für Stockwerk 24 beispielsweise dem Aufzug B zugeteilt wird, so laufen die gleichen vorstehend geschilderten Vorgänge ab, wobei jedoch der Ausgang des dem Aufzug B zugeordneten UND-Gliedes 76 den Zustand "1" aufweist, so dass der Buchstabe B des dritten Anzeigeelementes 80 und das fünfte Anzeigeelement 82 aktiviert werden (Fig. 5). Hat ein Fahrgast beispielsweise mittels der anderen Rufregistrier-und Anzeigeeinrichtung BC eine Zahl für ein nicht vorhandenes Stockwerk eingegeben, so wird, wie anhand der Fig. 1, 2a, 2b beschrieben, das zweite Anzeigeelement 60 aktiviert und das doppelte Fragezeichen signalisiert (Fig. 6).It is assumed that a passenger, for example on floor 15, uses the one call registration and display device AB to enter a call for floor 24. Here, as described with reference to FIGS. 1, 2a, 2b, the first display element 50 lights up accordingly. After the passenger has removed his hand from the keyboard 20, the call, as described in EP-A-0 246 395 already cited, is fed to the group control and the elevator which can best serve the call is immediately determined. It is now further assumed that the call has been allocated to elevator A, and the allocation may be final. As is known from the aforementioned document and EP-B 0 050 304, a program runs in the microcomputer system 73a, by means of which an assignment instruction relating to the call is written into an assignment memory. At the end of the program, the microcomputer system 73a sets the address of the floor 15 on the address bus and releases the address decoder 74 of the elevator A via the module enable line ce. The output of the relevant address decoder 74 therefore becomes "1", so that the associated monoflop 75 is switched. Since the AND gates 76 are enabled when the monoflop 34 (FIG. 1) of the activated call registration and display device AB is activated, the output of the AND gates 76 assigned to the elevator A has the state "1", so that the letter A of the third display element 80 and the fourth display element 81 are activated. Thus, the assigned elevator and its position in relation to the actuated call registration and display device are displayed to the passenger immediately after the entry of the call (FIG. 4). After the monoflop 75 has been switched on for two seconds, for example, the third and fourth display elements 80, 81 extinguish simultaneously with the first display element 50 signaling the entered floor number. If the If call for floor 24 is assigned to elevator B, for example, the same processes described above take place, but the output of the AND gate 76 assigned to elevator B has the state "1", so that the letter B of the third display element 80 and the fifth display element 82 can be activated (FIG. 5). If, for example, a passenger has entered a number for a floor that does not exist using the other call registration and display device BC, the second display element 60 is activated and the double question mark is signaled (FIG. 6, as described with reference to FIGS. 1, 2a, 2b) ).

In einer bevorzugten, nicht weiter beschriebenen Ausführungsform ist die Signalisierung des ersten Anzeigelementes 50 bis zum Einschalten des betreffenden Monoflops 75, und die Signalisierung des vierten bzw. fünften Anzeigeelementes 81, 82 während dessen gesamter Einschaltdauer intermittierend. Anstelle des in der Beschreibung der Fig. 1 erwähnten, nach dem kapazitiven Detektionsprinzip arbeitenden Näherungsschalters 28, können beispielsweise auch Infrarot-Reflexsensoren oder Temperatursensoren verwendet werden.In a preferred embodiment, which is not further described, the signaling of the first display element 50 is intermittent until the relevant monoflop 75 is switched on, and the signaling of the fourth or fifth display element 81, 82 is intermittent during its entire switch-on period. Instead of the proximity switch 28 mentioned in the description of FIG. 1, which operates according to the capacitive detection principle, it is also possible, for example, to use infrared reflex sensors or temperature sensors.
