Abstract

A group control for an elevator system, in which it is possible to assign a newly entered floor call to a car for the first time, immediately and finally, includes a computer and a comparator circuit for calculating servicing costs and assigning the call to the car with the lowest cost during a comparison cycle. The floor call generates an entry floor signal which is stored in a floor call memory and an assignment memory for the assigned car. Storage cells of the assignment memory and the floor call memory are linked to each other by way of an automatic holding circuit that prevents reassignment of the floor call during subsequent comparison cycles.

Description

Die Erfindung betrifft eine Gruppensteuerung für Aufzüge mit Sofortzuteilung von Zielrufen, mit auf den Stockwerken angeordneten Rufregistriereinrichtungen, mittels welchen Rufe für gewünschte Zielstockwerke eingegeben werden können, mit den Aufzügen der Gruppe zugeordneten Stockwerk- und Kabinenrufspeichern, die mit den Rufregistriereinrichtungen verbunden sind, wobei bei der Eingabe von Rufen auf einem Stockwerk ein das Eingabestockwerk kennzeichnender Ruf im Stockwerkrufspeicher gespeichert wird und die die Zielstockwerke kennzeichnenden Rufe im Kabinenrufspeicher gespeichert werden, und mit in den Kabinen der Aufzugsgruppe vorgesehenen Lastmesseinrichtungen, mit jedem Aufzug der Gruppe zugeordneten, jeweils das Stockwerk eines möglichen Anhaltens anzeigenden Selektoren, mit jedem Aufzug der Gruppe zugeordneten, für jedes Stockwerk mindestens eine Stellung aufweisenden ersten und zweiten Abtastern und mit einer Einrichtung, mittels welcher die eingegebenen Rufe den Kabinen der Aufzugsgruppe zugeteilt werden, gemäss Oberbegriff des Patentanspruches 1.The invention relates to a group control for elevators with immediate assignment of destination calls, with call registration devices arranged on the floors, by means of which calls for desired destination floors can be entered, with the storeys and car call store memories assigned to the elevators, which are connected to the call registration devices, in which case Input of calls on a floor a call characterizing the input floor is stored in the floor call memory and the calls characterizing the target floors are stored in the car call memory, and with load measuring devices provided in the cars of the elevator group, with each elevator assigned to the group, each indicating the floor of a possible stopping Selectors, assigned to each elevator of the group, having at least one position for each floor and having a device by means of which the calls entered enter the cars d he elevator group can be allocated, according to the preamble of claim 1.

Bei einer derartigen mit der EP-A- 0 246 395 bekannt gewordenen Gruppensteuerung können die Zuordnungen der Kabinen zu den eingegebenen Rufen zeitlich optimiert werden. Der Kabinenrufspeicher eines Aufzuges dieser Grupensteuerung besteht aus einem ersten, bereits zugeteilte Kabinenrufe enthaltenden Speicher und den Stockwerken zugeordneten weiteren Speichern, in welchen die auf den betreffenden Stockwerken für gewünschte Zielstockwerke eingegebenen, noch nicht einer Kabine zugeteilten Rufe gespeichert sind. Eine Einrichtung, mittels welcher die eingegebenen Rufe den Kabinen der Aufzugsgruppe zugeteilt werden, weist einen Rechner in Form eines Mikroprozessors und eine Vergleichseinrichtung auf. Der Rechner errechnet während eines Abtastzyklusses eines ersten Abtasters einer Abtasteinrichtung bei jedem Stockwerk aus mindestens der Distanz zwischen dem Stockwerk und der von einem Selektor angezeigten Kabinenposition, den innerhalb dieser Distanz zu erwartenden Zwischenhalten und der Last in der Kabine, eine den Zeitverlusten von wartenden Fahrgästen auf den Stockwerken und in der Kabine proportionale Summe. Treffen die ersten Abtaster auf einen noch nicht zugeteilten Stockwerkruf, so müssen die auf diesem Stockwerk für gewünschte Zielstockwerke eingegebenen, in den weiteren Speichern des Kabinenrufspeichers gespeicherten Rufe mit in Rechnung gestellt werden. Es wird daher eine zusätzliche, den Zeitverlusten der Fahrgäste in der Kabine proportionale Summe ermittelt und eine Gesamtsumme gebildet. Diese, auch Bedienungskosten genannte Gesamtsumme, wird in einem Kostenspeicher gespeichert. Während eines Abtastzyklusses eines zweiten Abtasters der Abtasteinrichtung werden die Bedienungskosten aller Aufzüge mittels der Vergleichseinrichtung miteinander verglichen, wobei jeweils in einem Zuteilungsspeicher des Aufzuges mit den geringsten Bedienungskosten eine Zuteilungsanweisung gespeichert wird, die dasjenige Stockwerk bezeichnet, dem die betreffende Kabine zeitlich optimal zugeordnet ist.With such a group control, which has become known from EP-A-0 246 395, the assignments of the cars to the entered calls can be optimized in terms of time. The car call memory of an elevator of this group control consists of a first memory which already contains allocated car calls and further memories assigned to the floors, in which the calls which have been entered on the relevant floors for desired destination floors and have not yet been allocated to a car are stored. A device by means of which the entered calls are allocated to the cabins of the elevator group has a computer in the form of a microprocessor and one Comparison device. During a scanning cycle of a first scanner of a scanning device on each floor, the computer calculates the time lost by waiting passengers from at least the distance between the floor and the cabin position indicated by a selector, the intermediate stops to be expected within this distance and the load in the cabin Total proportional to the floors and in the cabin. If the first scanner encounters an as yet unallocated floor call, then the calls entered on this floor for the desired destination floors and stored in the further memories of the cabin call memory must also be taken into account. An additional sum proportional to the time lost by the passengers in the cabin is therefore determined and a total sum is formed. This total, also called operating costs, is stored in a cost memory. During a scanning cycle of a second scanner of the scanning device, the operating costs of all elevators are compared with one another by means of the comparison device, an allocation instruction being stored in an allocation memory of the elevator with the lowest operating costs, which indicates the floor to which the relevant car is optimally assigned in terms of time.

Bei dieser Steuerung werden unmittelbar nach der Eingabe eines Rufes für ein gewünschtes Zielstockwerk die Bedienungkosten errechnet, wobei mittels des anschliessenden Vergleiches die sofortige Zuteilung des Rufes an die Kabine mit den günstigsten Bedienungskosten erfolgt. Da jedoch bei Änderungen der Verkehrssituation und entsprechenden Neuberechnungen der Bedienungskosten andere Vergleichsergebnisse entstehen können, kann ein erstmalig einer bestimmten Kabine zugeteilter Ruf einer anderen Kabine zugeteilt werden, wenn er noch nicht der Antriebssteuerung des betreffenden Aufzuges übergeben wurde. Hierbei können für die auf einem Stockwerk auf eine Kabine wartenden Fahrgäste Schwierigkeiten entstehen, da es nicht möglich ist, die letztendlich zugeteilte Kabine rechtzeitig genug zu signalisieren.With this control, the service costs are calculated immediately after the entry of a call for a desired destination floor, the subsequent assignment of the call to the cabin with the cheapest service costs being carried out by means of the subsequent comparison. However, since changes in the traffic situation and corresponding recalculation of the operating costs may result in different comparison results, a call assigned to a particular car for the first time can be assigned to another car if it has not yet been transferred to the drive control of the elevator in question. This allows passengers waiting for a cabin on one floor Difficulties arise because it is not possible to signal the ultimately allocated cabin in good time.

Es ist daher Aufgabe der Erfindung, eine Gruppensteuerung gemäss Oberbegriff zu schaffen, bei welcher das Rufzuteilungsverfahren eine rechtzeitige Anzeige der zugeteilten Kabine ermöglicht.It is therefore an object of the invention to provide a group control according to the preamble, in which the call allocation method enables the allocated cabin to be displayed in good time.

Diese Aufgabe wird durch die im Patentanspruch 1 gekennzeichnete Erfindung gelöst. Hierbei ist je Aufzug ein Selbsthalte-Schaltkreis vorgesehen, der bewirkt, dass ein erstmalig zugeteilter Ruf einer Kabine zugeteilt bleibt, bis er von der betreffenden Antriebssteuerung übernommen wird.This object is achieved by the invention characterized in claim 1. In this case, a self-holding circuit is provided for each elevator, which has the effect that an initially assigned call remains assigned to a car until it is taken over by the relevant drive control.

Die mit der Erfindung erzielten Vorteile liegen darin, dass sofort nach der erstmaligen Zuteilung eines Rufes die betreffende Kabine signalisiert werden kann, so dass für die auf einem Stockwerk wartenden Fahrgäste genügend Zeit verbleibt, die Anzeige zu erkennen und sich rechtzeitig zum signalisierten Aufzug zu begeben.The advantages achieved by the invention are that the relevant cabin can be signaled immediately after the first assignment of a call, so that there is sufficient time for the passengers waiting on one floor to recognize the display and to go to the signaled elevator in good time.

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

In der Fig.1 sind mit A und B zwei Aufzüge einer Aufzugsgruppe bezeichnet, wobei bei jedem Aufzug eine in einem Aufzugsschacht 1 geführte Kabine 2 von einer Fördermaschine 3 über ein Förderseil 4 angetrieben wird und dreizehn Stockwerke E0 bis E12 bedient werden. Die Fördermaschine 2 wird von einer aus der EP-B- 0 026 406 bekannten Antriebssteuerung gesteuert, wobei die Sollwerterzeugung, die Regelfunktionen und die Stoppeinleitung mittels eines Mikrocomputersystems 5 realisiert werden, das mit Mess- und Stellgliedern 6 der Antriebssteuerung in Verbindung steht. Das Mikrocomputersystem 5 berechnet ausserdem aus aufzugsspezifischen Parametern eine der durchschnittlichen Wartezeit aller Fahrgäste entsprechende Summe, auch Bedienungskosten genannt, die dem Rufzuteilungsverfahren zugrunde gelegt wird. Die Kabine 2 weist eine Lastmesseinrichtung 7 auf, die ebenfalls mit dem Mikrocomputersystem 5 verbunden ist. Auf den Stockwerken sind Rufregistriereinrichtungen 8 in Form von 10er-Tastaturen vorgesehen, mittels welchen Rufe für Fahrten zu gewünschten Zielstockwerken eingegeben werden können. Die Rufregistriereinrichtungen 8 sind über einen Adressenbus AB und einen Dateneingabeleiter CRUIN mit dem Mikrocomputersystem 5 und einer mit der EP-B- 0 062 141 bekanntgewordenen Eingabeeinrichtung 9 verbunden. Die Rufregistriereinrichtungen 8 können mehr als einem Aufzug der Gruppe zugeordnet sein, wobei beispielsgemäss diejenigen des Aufzuges A über Koppelglieder in Form von Multiplexern 10 mit dem Mikrocomputersystem 5 und der Eingabeeinrichtung 9 des Aufzuges B in Verbindung stehen. Die Mikrocomputersysteme 5 der einzelnen Aufzüge der Gruppe sind über eine aus der EP-B- 0 050 304 bekannte Vergleichseinrichtung 11 und ein aus der EP-B- 0 050 305 bekanntes Partyline-Übertragungssystem 12 miteinander verbunden und bilden zusammen mit den Rufregistrier- und Eingabeeinrichtungen 8, 9 in dieser Weise eine Gruppensteuerung, die strukturell mit einer in der EP-A- 0 246 395 beschriebenen Gruppensteuerung übereinstimmt.In FIG. 1, A and B designate two elevators of an elevator group, with each elevator driving a car 2 guided in an elevator shaft 1 by a conveyor 3 via a conveyor cable 4 and serving thirteen floors E0 to E12. The carrier 2 is controlled by a drive control known from EP-B-0 026 406, the setpoint generation, the control functions and the start of the stop being implemented by means of a microcomputer system 5 which is connected to measuring and actuating elements 6 of the drive control. The microcomputer system 5 also calculates from elevator-specific parameters a sum corresponding to the average waiting time of all passengers, also called service costs, which is used as the basis for the call allocation process. The cabin 2 has a load measuring device 7, which is also connected to the microcomputer system 5. Call registering devices 8 in the form of 10-keyboards are provided on the floors, by means of which calls can be entered for trips to the desired destination floors. The call registration devices 8 are connected via an address bus AB and a data input conductor CRUIN to the microcomputer system 5 and to an input device 9 which has become known from EP-B-0 062 141. The call registration devices 8 can be assigned to more than one elevator of the group, wherein, for example, those of the elevator A are connected to the microcomputer system 5 and the input device 9 of the elevator B via coupling links in the form of multiplexers 10. The microcomputer systems 5 of the individual elevators in the group are connected to one another via a comparison device 11 known from EP-B-0 050 304 and a party line transmission system 12 known from EP-B-0 050 305 and form together with the call registration and input devices 8, 9 in this way a group control which structurally corresponds to a group control described in EP-A-0 246 395.

Mit 13 ist ein Selbsthalte-Schaltkreis bezeichnet, der mit Komponenten des Mikrocomputersystems 5 verbunden ist und nachstehend anhand der Fig.3 näher erläutert wird.13 denotes a self-holding circuit, which is connected to components of the microcomputer system 5 and is explained in more detail below with reference to FIG. 3.

Der Kabinenrufspeicher RAM2 besteht aus einem ersten Speicher RAM2', welcher der Anzahl der Stockwerke entsprechende Speicherplätze aufweist, in dem bereits zugeteilte Rufe gespeichert sind. Der Kabinenrufspeicher RAM2 weist ausserdem weitere, den Stockwerken E0, E1....E12 zugeordnete Speicher RAM2.0, RAM2.1.....RAM2.12 auf, die ebenfalls der Anzahl der Stockwerke entsprechende Speicherplätze besitzen, in welche die an den betreffenden Stockwerken eingegebenen Rufe übertragen werden, die noch keiner bestimmten Kabine zugeteilt sind. So werden gemäss Beispiel Fig.2 auf dem Stockwerk E5 eingegebene Rufe für die Stockwerke E7 und E9 in den weiteren Speicher RAM2.5 übertragen, wobei gleichzeitig im Stockwerkrufspeicher RAM1 ein Ruf für Stockwerk E5 gespeichert wird. Entsprechend der üblichen logischen Symbolik sind die gespeicherten Rufe in der Fig.2 mit "1" gekennzeichnet.According to EP-A-0 246 395 mentioned above, the microcomputer system 5 shown partially schematically in FIG. 2 has a floor call memory RAM1, a car call memory RAM2, a cost memory RAM4, an allocation memory RAM5, a first and second scanner R1 and R2 and a selector R3 on. The car call memory RAM2 consists of a first memory RAM2 ', which has memory locations corresponding to the number of floors, in which calls which have already been allocated are stored. The car call memory RAM2 also has further memories RAM2.0, RAM2.1 ..... RAM2.12 assigned to the floors E0, E1 .... E12, which also have memory locations corresponding to the number of floors into which the calls entered into the relevant floors are transmitted which have not yet been assigned to a specific car. Calls for floors E7 and E9 entered on floor E5 are transmitted to the further memory RAM2.5 in accordance with example FIG. 2, a call for floor E5 being simultaneously stored in floor call memory RAM1. In accordance with the usual logical symbolism, the stored calls are marked with "1" in FIG.

The data output Q the memory cell 23 is also connected via the NOT gate 21 to one input of the fourth AND gate 17, the output of which is connected to the other input of the first OR gate 18. The other inputs of the second and fourth AND elements 15 and 17 are supplied with an assignment instruction Co which can be generated during a comparison process in accordance with the aforementioned EP-B-0 050 304. The output of the first AND gate 14 is also connected to one input of the third AND gate 16, the other input a 'of which is connected to the selector R3 (FIG. 2) and the output of which is connected to the drive control of the elevator in question. The self-holding circuit 13 can be formed by the microprocessor of the microcomputer system 5 on the basis of a program at each position of the second scanner R2 (FIG. 2) for the floor in question.

Die Arbeitsweise der vorstehend beschriebenen Gruppensteuerung wird im folgenden an Hand der Fig.2 und 3 näher erläutert:
Gemäss der eingangs genannten EP-A- 0 246 395 wird bei Eingabe eines Rufes bei allen Aufzügen der Gruppe eine Bedienungskostenberechnung ausgelöst und bei jedem vom ersten Abtaster R1 bezeichneten Stockwerk durchgeführt. Die hierbei errechneten Bedienungskosten werden pro Stockwerk im Kostenspeicher RAM4 gespeichert. Wie weiterhin aus vorgenannter Druckschrift bekannt, wird nach Ablauf eines Kostenberechnungszyklusses ein Kostenvergleichszyklus durchgeführt. Hierbei werden die in den Kostenspeichern RAM4 aller Aufzüge gespeicherten Bedienungskosten der jeweils vom zweiten Abtaster R2 bezeichneten Stockwerke miteinander verglichen und der betreffende Ruf derjenigen Kabine zugeteilt, welche die kleinsten Bedienungskosten aufweist.
The mode of operation of the group control described above is explained in more detail below with reference to FIGS. 2 and 3:
According to EP-A-0 246 395 mentioned at the outset, when a call is entered, an operating cost calculation is triggered for all elevators in the group and is carried out on each floor designated by the first scanner R1. The operating costs calculated here are stored in the RAM4 cost memory per floor. As is also known from the aforementioned publication, a cost comparison cycle is carried out after the end of a cost calculation cycle. In this case, the operating costs of the floors designated by the second scanner R2 stored in the cost memories RAM4 of all elevators are compared with one another and the relevant call is allocated to the cabin that has the lowest operating costs.

Bei der Eingabe von Rufen, beispielsweise auf dem Stockwerk E5 für die Zielstockwerke E7 und E9 werden im Stockwerkrufspeicher RAM1 ein Stockwerkruf für Stockwerk E5 und im weiteren Speicher RAM2.5 die Rufe für die Zielstockwerke E7 und E9 gespeichert. Es möge nun angenommen sein, dass beim ersten Vergleich nach der Rufeingabe der Stockwerkruf E5 dem Aufzug A zugeteilt wird, wobei wie aus der eingangs genannten EP-A- 0 246 395 ersichtlich, die im weiteren Speicher RAM2.5 gespeicherten Rufe E7 und E9 in den ersten Speicher RAM2' des Kabinenrufspeichers RAM2 übertragen werden. Beim Vergleich von Stockwerk E5 wird durch die vom Abtaster R2 erzeugte Adresse a=1, so dass mit we=1 und a=1 an den Eingängen des UND-Gliedes 24 und Co=1 am anderen Eingang des vierten UND-Gliedes 17 die dem Stockwerk E5 zugeordnete Speicherzelle 22 des Zuteilungsspeichers RAM5 des Aufzuges A gesetzt und deren Datenausgang Q=0 wird. Da bei einem gespeicherten Ruf für Stockwerk E5 der Datenausgang Q der betreffenden Speicherzelle 23 des Stockwerkrufspeichers RAM1 ebenfalls "0" ist, werden der Ausgang des ersten UND-Gliedes 14 und damit auch der eine Eingang des ersten ODER-Gliedes 18 auf "1" gesetzt. Es soll weiterhin angenommen sein, dass der Ruf für Stockwerk E5 noch vor Übergabe an die Antriebssteuerung des Aufzuges A durch einen neuen Vergleich dem Aufzug B zugeteilt wird. In diesem Falle wird zum Zwecke des Löschens der betreffenden Speicherzelle 22 des Zuteilungsspeichers RAM5 für Aufzug A eine Zuteilungsanweisung Co=0 erzeugt, die sich jedoch nicht auswirken kann, da der Dateneingang D der Speicherzelle 22 über den einen Eingang des ODER-Gliedes 18 auf "1" gehalten wird. Auf diese Weise kann der bei einem ersten Vergleich dem Aufzug A zugeteilte Stockwerkruf E5 keinem anderen Aufzug der Gruppe mehr zugeteilt werden. Liegt der zugeteilte Ruf in Fahrtrichtung der Kabine 2 des Aufzuges A und schaltet der Selektor R3 auf die Adresse des Stockwerkes E5, so wird a'=1, womit am Ausgang des dritten UND-Gliedes 16 ein Signal "1" auftritt, das von der Antriebssteuerung des Aufzuges A als Fahrbefehl zum Stockwerk E5 interpretiert wird.When calls are entered, for example on the floor E5 for the destination floors E7 and E9, a floor call for floor E5 is stored in the floor call memory RAM1 and the calls for the destination floors E7 and E9 are stored in the further memory RAM2.5. It may now be assumed that in the first comparison after the call input, the floor call E5 is assigned to the elevator A, the calls E7 and E9 stored in the further memory RAM2.5 being evident from the aforementioned EP-A-0 246 395 the first memory RAM2 'of the car call memory RAM2 are transferred. When comparing floor E5, the address generated by the scanner R2 a = 1, so that with we = 1 and a = 1 at the inputs of the AND gate 24 and Co = 1 at the other input of the fourth AND gate 17, the Memory cell 22 assigned to floor E5 of allocation memory RAM5 of elevator A is set and its data output Q = 0. Since the data output Q of the relevant memory cell 23 of the storey call memory RAM1 is also "0" in the case of a stored call for floor E5, the output of the first AND gate 14 and thus also the one input of the first OR gate 18 are set to "1" . It should also be assumed that the call for floor E5 is passed through a new comparison before transfer to the drive control of elevator A. is assigned to elevator B. In this case, for the purpose of deleting the relevant memory cell 22 of the allocation memory RAM5 for elevator A, an allocation instruction Co = 0 is generated which, however, cannot have an effect since the data input D of the memory cell 22 via the one input of the OR gate 18 to " 1 "is held. In this way, the floor call E5 allocated to elevator A in a first comparison can no longer be allocated to any other elevator in the group. If the assigned call is in the direction of travel of the car 2 of the elevator A and the selector R3 switches to the address of the floor E5, then a '= 1, so that a signal "1" occurs at the output of the third AND gate 16, which is from the Drive control of elevator A is interpreted as a travel command to floor E5.

Bei der erstmaligen Zuteilung des Stockwerkes E5 an den Aufzug A werden die Zuteilungsanweisungen Co für die anderen Aufzüge der Gruppe "0". Hierbei wird bei diesen Aufzügen bei we=1 und a=1 an den Eingängen des UND-Gliedes 25 und Co=0 am anderen Eingang des zweiten UND-Gliedes 15 die betreffende Speicherzelle 23 des Stockwerkrufspeichers RAM1 gelöscht. Wenn, wie vorstehend geschildert, bei einem neuen Vergleich das Stockwerk E5 dem Aufzug B zugeteilt wird, so wird bei diesem Aufzug bei we=1, a=1 und Co=1 die betreffende Speicherzelle 22 des Zuteilungsspeichers RAM5 nicht gesetzt, da die Speicherzelle 23 des Stockwerkrufspeichers RAM1 bei der Zuteilung an den Aufzug A gelöscht wurde und somit der mit dem Ausgang des ersten UND-Gliedes 14 verbundene Eingang des ersten ODER-Gliedes 18 sowie der eine Eingang des vierten UND-Gliedes 17 den Zustand "0" aufweisen.When floor E5 is assigned to elevator A for the first time, allocation instructions Co for the other elevators in group become "0". With these lifts, if we = 1 and a = 1 at the inputs of the AND gate 25 and Co = 0 at the other input of the second AND gate 15, the relevant memory cell 23 of the storey call memory RAM1 is deleted. If, as described above, the floor E5 is allocated to the elevator B in a new comparison, then with this elevator, if we = 1, a = 1 and Co = 1, the relevant memory cell 22 of the allocation memory RAM5 is not set, since the memory cell 23 of the storey call memory RAM1 was deleted when it was allocated to the elevator A, and thus the input of the first OR gate 18 connected to the output of the first AND gate 14 and one input of the fourth AND gate 17 have the state "0".
