Definitions
- the invention relates to a method and system for modernizing an elevator system according to the definition of the preambles of the independent claims.
- Elevators for the transport of persons / goods are relatively durable capital goods with lifetimes of 20 years and more. If after such a long time a major overhaul of an elevator system is pending, the components of the elevator system are technologically often obsolete, which makes a more or less complete replacement of the components necessary, which is called modernization below.
- a disadvantage of this method of modernizing an elevator installation is that the transport capacity of the elevator installation is at best maintained during the modernization. If an elevator is exchanged in an elevator installation with, for example, three elevators, this means a temporary reduction of the transport capacity by 33%. Users, on the other hand, do not want to suffer comfort during modernization and continue to be promoted as quickly and directly as possible. Long waiting times or awkward transfers are perceived as unpleasant.
- the object of the invention is to provide a method and a system in which waiting times or changes perceived as detrimental to the user during the modernization of an elevator installation are largely avoided.
- This method should be cost-effective and compatible with established standards in mechanical engineering and the electronics industry.
- an elevator system located in a building is modernized with several elevators in a building.
- On at least one floor of the building is at least one floor terminal for entering a landing call.
- the floor terminal is connected to a group controller for communicating an inputted floor call.
- At least one elevator is controlled by the group control according to the communicated floor call.
- At least one call detection unit is connected to the group controller for communicating an inputted floor call.
- At least one new floor terminal will be installed on at least one floor for entering a landing call.
- the new floor terminal is connected to the call detection unit for communication of an inputted floor call.
- the existing floor terminals are made inaccessible.
- a floor call is entered via a new floor terminal, which floor call is communicated to the call detection unit and from there is communicated directly or indirectly to the group control.
- This has the advantage that on this floor a floor call can only be entered at a new floor terminal.
- a user is prevented from entering a floor call several times, at an old floor terminal and at a new floor terminal.
- Such a multiple entry of a landing call unnecessarily reduces the transport capacity of the elevator installation.
- a new group control is installed. At least one elevator is relocated from the existing group control to the new group control. The suspended elevator is controlled by the new group controller and the call detection unit is connected to the new group controller for communication of an entered floor call.
- the call detection unit not only communicates with the old group control, but also with the new group control.
- the call detection unit may communicate with the group controllers in a direct or indirect manner. This makes it possible to adapt the traffic volume during modernization to the changing transport capacity of the elevator installation.
- the call detection unit is an independent unit or component of a floor terminal.
- several call detection units are mounted per floor.
- floor calls entered on the new floor terminal are distributed according to at least one rule to the existing group control and to the new group control.
- a random distribution or an alternating distribution or a performance-related distribution is used as a rule. This has the advantage that if the new group control is more efficient, ie has a higher capacity than the existing group control, entered floor calls will be specifically allocated to this more powerful new group control.
- at least one floor, preferably on each floor is fitted with at least one new floor terminal for entering a floor call, and the new floor terminals are connected to the call detection unit for communication of an entered floor call.
- the starting floor of the entered floor call is communicated by the call detection unit as a start signal to the group control, and the group control communicates the receipt of the entered landing call as an acknowledgment signal to the call detection unit.
- the call detection unit detects the deactivation of the acknowledgment signal, whereupon the call detection unit communicates the destination floor of the entered floor call as the destination signal to the group control.
- the new floor terminal is a start-up call terminal or a destination call terminal. If the new floor terminal is a destination call terminal, existing car terminals are made inaccessible. This also avoids multiple entry of a call, once as a destination call at the destination call terminal and then as a car call in the car terminal, which reduces the transport capacity of the elevator system.
- the call detection unit is dismantled after transferring the last of the elevators from the existing group control to the new group control.
- the call detection unit can thus be used again in further modernizations.
- the call detection unit or a new floor terminal on an interface for picking up signals such as start signals, acknowledgment signals and destination signals.
- signals can be easily and quickly tapped in future modernizations.
- Fig. 1 shows a schematic view of a part of an elevator system to be modernized. More details are off Fig. 2 refer to.

- Fig. 1 located on each floor 20, 20 ', 20 "of the building at least one floor terminal 2, 2', 2".
- Fig. 2 is located on each floor 20, 20 ', 20 "next to each elevator A, B, C exactly one floor terminal 2, 2', 2".
- a floor call indicates to the group controller 5 the start floor from which a user wants to be moved with a lift A, B, C in the building.
- the elevators A, B, C are controlled by the group control 5 according to the communicated floor call.
- this call is communicated as a start floor to the group control 5.

- the group controller 5 confirms receipt of the landing call by activating an acknowledgment lamp 21, 21 ', 21 ", 23, 23', 23" in the start floor.
- the receipt of a landing call for an upward drive is confirmed with an acknowledgment lamp 21, 21 ', 21 "
- the receipt of a landing call for a downward drive is confirmed with an acknowledgment lamp 23, 23', 23".
- the activation of an acknowledgment lamp 21, 21 ', 21 ", 23, 23', 23” takes place, for example, by applying an electrical voltage to two outputs of the acknowledgment lamp 21, 21 ', 21 ", 23, 23', 23", so that these is supplied with electricity and lights up.
- the group control 5 thus communicates bidirectionally with the floor terminals 2, 2 ', 2 ", which are notified as a start signal of which call button 22, 22', 22", 24, 24 ', 24 on which floor terminals 2, 2 ', 2 "from which floor 20, 20', 20" has been actuated and confirms the receipt of such floor call with an acknowledgment signal by activating a call button 22, 22 ', 22 ", 24, 24
- the acknowledgment lamp 21, 21 ', 21 ", 23, 23', 23” is deactivated only when the elevator car 11, 11 ', 21 ", 21", 21 ", 23, 23', 23” are assigned ', 11 "into the start floor.

- the group control 5 confirms the receipt of the car call by activating an acknowledgment lamp 121, 123, 125.
- an acknowledgment lamp 121, 123, 125 takes place, for example, by applying an electrical voltage via communication lines 127 to two outputs of the acknowledgment lamp 121, 123, 125, so that this is supplied with electricity and lights up.
- This acknowledgment signal is likewise generated by the group controller 5.
- the acknowledgment lamp 121, 123, 125 is only deactivated when the elevator car 11, 11 ', 11 "has moved into the destination floor.

As part of the modernization of the elevator installation, such signal lines can be easily and quickly laid between the floor terminals 2, 2 ', 2 "and the call detection unit 40. In particular, such signal lines can be routed without adversely affecting the transport capacity of the elevator installation connected to all floor terminals 2, 2 ', 2 "on all floors 20, 20', 20".
- the call detection unit 40 has a larger number of inputs and outputs for bidirectional communication via communication lines 213, 213 ', 213 ", 224, 224', 224", 413, 424, 428.

Aufzugsanlagen zur Beförderung von Personen/Gütern sind relativ langlebige Investitionsgütern mit Lebensdauern von 20 Jahren und mehr. Wenn nach einer derart langen Zeit eine Generalüberholung einer Aufzugsanlage ansteht, so sind die Komponenten der Aufzugsanlage technologisch oft veraltet, was einen mehr oder weniger vollständigen Austausch der Komponenten nötig macht, was im Folgenden Modernisierung genannt wird.Elevators for the transport of persons / goods are relatively durable capital goods with lifetimes of 20 years and more. If after such a long time a major overhaul of an elevator system is pending, the components of the elevator system are technologically often obsolete, which makes a more or less complete replacement of the components necessary, which is called modernization below.
Nachteilig an diesem Verfahren der Modernisierung einer Aufzugsanlage ist, dass die Transportkapazität der Aufzugsanlage während der Modernisierung bestenfalls aufrechterhalten wird. Wird bei einer Aufzugsanlage mit beispielsweise drei Aufzügen ein Aufzug ausgetauscht, so bedeutet dies eine temporäre Reduktion der Transportkapazität um 33%. Die Benutzer hingegen wollen während der Modernisierung keine Komforteinbussen erleiden und weiterhin möglichst rasch und direkt befördert werden. Lange Wartezeiten bzw. umständliches Umsteigen werden als unangenehm empfunden.A disadvantage of this method of modernizing an elevator installation is that the transport capacity of the elevator installation is at best maintained during the modernization.

Advantageously, on the floor where a new floor terminal is mounted, the existing floor terminals are made inaccessible.
Somit wird bei der Modernisierung ein Stockwerkruf über ein neues Stockwerkterminal eingegeben, welcher Stockwerkruf an die Ruferfassungseinheit kommuniziert wird und von dort in direkter oder indirekter Art und Weise an die Gruppensteuerung kommuniziert wird. Dies hat den Vorteil, dass auf diesem Stockwerk ein Stockwerkruf nur an einem neuen Stockwerkterminal eingegeben werden kann. Somit wird vermieden, dass ein Benutzer einen Stockwerkruf mehrmals, an einem alten Stockwerkterminal und an neuen Stockwerkterminal eingibt. Eine solche Mehrfacheingabe eines Stockwerkrufs reduziert die Transportkapazität der Aufzugsanlage unnötig.Thus, in the modernization, a floor call is entered via a new floor terminal, which floor call is communicated to the call detection unit and from there is communicated directly or indirectly to the group control. This has the advantage that on this floor a floor call can only be entered at a new floor terminal. Thus, a user is prevented from entering a floor call several times, at an old floor terminal and at a new floor terminal. Such a multiple entry of a landing call unnecessarily reduces the transport capacity of the elevator installation.
Weitere vorteilhafte Ausgestaltungen der Erfindungen werden in den anhängigen Patentansprüchen definiert.Further advantageous embodiments of the inventions are defined in the appended claims.
Vorteilhafterweise wird daraufhin eine neue Gruppensteuerung installiert. Mindestens ein Aufzug wird von der bestehenden Gruppensteuerung auf die neue Gruppensteuerung umgehängt. Der umgehängte Aufzug wird von der neuen Gruppensteuerung angesteuert und die Ruferfassungseinheit wird zur Kommunikation eines eingegebenen Stockwerkrufs mit der neuen Gruppensteuerung verbunden.Advantageously, then a new group control is installed. At least one elevator is relocated from the existing group control to the new group control. The suspended elevator is controlled by the new group controller and the call detection unit is connected to the new group controller for communication of an entered floor call.
Die Ruferfassungseinheit kommuniziert also nicht nur mit der alten Gruppensteuerung, sondern auch mit der neuen Gruppensteuerung. Die Ruferfassungseinheit kann auf direkte oder indirekte Art und Weise mit den Gruppensteuerungen kommunizieren. Das erlaubt es, das Verkehrsaufkommen während der Modernisierung an die sich ändernde Transportskapazität der Aufzugsanlage anzupassen.The call detection unit not only communicates with the old group control, but also with the new group control. The call detection unit may communicate with the group controllers in a direct or indirect manner. This makes it possible to adapt the traffic volume during modernization to the changing transport capacity of the elevator installation.
Vorteilhafterweise ist die Ruferfassungseinheit eine eigenständige Einheit oder Bestandteil eines Stockwerkterminals. Vorteilhafterweise sind pro Stockwerk mehrere Ruferfassungseinheiten montiert.Advantageously, the call detection unit is an independent unit or component of a floor terminal. Advantageously, several call detection units are mounted per floor.
Vorteilhafterweise werden auf dem neuen Stockwerkterminal eingegebene Stockwerkrufe gemäss mindestens einer Regel auf die bestehende Gruppensteuerung und auf die neue Gruppensteuerung verteilt. Vorteilhafterweise wird als Regel eine Zufallsverteilung oder eine alternierende Verteilung oder eine leistungsbezogene Verteilung verwendet. Dies hat den Vorteil, dass falls die neue Gruppensteuerung leistungsfähiger ist, also eine höhere Kapazität als die bestehende Gruppensteuerung hat, eingegebene Stockwerkrufe gezielt an diese leistungsfähigere neue Gruppensteuerung zugeteilt werden. Erfindungsgemäss wird auf mindestens einem Stockwerk vorzugsweise auf jedem Stockwerk mindestens ein neues Stockwerkterminal zum Eingeben eines Stockwerkrufs montiert und die neuen Stockwerkterminals werden zur Kommunikation eines eingegebenen Stockwerkrufs mit der Ruferfassungseinheit verbunden.Advantageously, floor calls entered on the new floor terminal are distributed according to at least one rule to the existing group control and to the new group control. Advantageously, a random distribution or an alternating distribution or a performance-related distribution is used as a rule. This has the advantage that if the new group control is more efficient, ie has a higher capacity than the existing group control, entered floor calls will be specifically allocated to this more powerful new group control. According to the invention, at least one floor, preferably on each floor, is fitted with at least one new floor terminal for entering a floor call, and the new floor terminals are connected to the call detection unit for communication of an entered floor call.
Vorteilhafterweise wird von der Ruferfassungseinheit das Startstockwerk des eingegebenen Stockwerkrufs als Startsignal an die Gruppensteuerung kommuniziert und von der Gruppensteuerung wird der Erhalt des eingegebenen Stockwerkrufs als Quittierungssignal an die Ruferfassungseinheit kommuniziert. Von der Ruferfassungseinheit wird die Deaktivierung des Quittierungssignals erfasst, woraufhin die Ruferfassungseinheit das Zielstockwerk des eingegebenen Stockwerkrufs als Zielsignal an die Gruppensteuerung kommuniziert. Dies hat den Vorteil, dass die Ruferfassungseinheit einen an einem neuen Stockwerkterminal eingegebenen Zielruf für die bisherige Gruppensteuerung übersetzt. Die Ruferfassungseinheit kommuniziert zuerst ein Startsignal und dann ein Zielsignal an die bisherige Gruppensteuerung.Advantageously, the starting floor of the entered floor call is communicated by the call detection unit as a start signal to the group control, and the group control communicates the receipt of the entered landing call as an acknowledgment signal to the call detection unit. The call detection unit detects the deactivation of the acknowledgment signal, whereupon the call detection unit communicates the destination floor of the entered floor call as the destination signal to the group control. This has the advantage that the call detection unit has a destination call entered at a new floor terminal translated for the previous group control. The call detection unit first communicates a start signal and then a destination signal to the previous group controller.
Vorteilhafterweise ist das neue Stockwerkterminal ein Startrufterminal oder ein Zielrufterminal. Falls das neue Stockwerkterminal ein Zielrufterminal ist, werden bestehende Kabinenterminals unzugänglich gemacht. Auch dies vermeidet eine Mehrfacheingabe eines Rufs, einmal als Zielruf am Zielrufterminal und dann als Kabinenruf im Kabinenterminal, was die Transportkapazität der Aufzugsanlage reduziert.Advantageously, the new floor terminal is a start-up call terminal or a destination call terminal. If the new floor terminal is a destination call terminal, existing car terminals are made inaccessible. This also avoids multiple entry of a call, once as a destination call at the destination call terminal and then as a car call in the car terminal, which reduces the transport capacity of the elevator system.
Vorteilhafterweise wird die Ruferfassungseinheit nach Umhängen des letzten der Aufzüge von der bestehenden Gruppensteuerung auf die neue Gruppensteuerung demontiert. Die Ruferfassungseinheit lässt sich somit bei weiteren Modernisierungen wieder verwenden.Advantageously, the call detection unit is dismantled after transferring the last of the elevators from the existing group control to the new group control. The call detection unit can thus be used again in further modernizations.
Vorteilhafterweise weist die Ruferfassungseinheit bzw. ein neues Stockwerkterminal eine Schnittstelle zum Abgreifen von Signalen wie Startsignale, Quittierungssignale und Zielsignale auf. Auf diese Weise lassen sich die Signale bei zukünftigen Modernisierungen einfach und rasch abgreifen.Advantageously, the call detection unit or a new floor terminal on an interface for picking up signals such as start signals, acknowledgment signals and destination signals. In this way, the signals can be easily and quickly tapped in future modernizations.

Zum Eingeben eines Stockwerkrufs ist mindestens ein Stockwerkterminal notwendig. Gemäss
Die Aufzüge A, B, C werden gemäss des kommunizierten Stockwerkrufs von der Gruppensteuerung 5 angesteuert. Sobald ein Benutzer auf einem Stockwerk 20, 20', 20" einen Stockwerkruf eingibt, wird dieser als Startstockwerk an die Gruppensteuerung 5 kommuniziert. Zur Bedienung des Stockwerkrufs wählt die Gruppensteuerung 5 eine Aufzugskabine 11, 11', 11" aus. Diese Aufzugskabine 11, 11', 11" wird in das Startstockwerk verfahren. Die Stockwerktür 1, 1', 1" und die Kabinentür der Aufzugskabine 11, 11', 11" werden geöffnet und der Benutzer kann die Aufzugskabine 11, 11', 11" betreten. In der Aufzugskabine 11, 11', 11" gibt der Benutzer daraufhin einen Kabinenruf auf. Zum Eingeben eines Kabinenrufs befindet sich in jeder Aufzugskabine 11, 11', 11" ein Kabinenterminal 12, 12', 12". Das Kabinenterminal 12, 12', 12" ist zur Kommunikation eines eingegebenen Kabinenrufs mit der Gruppensteuerung 5 verbunden. Der Kabinenruf wird als Zielstockwerk an die Gruppensteuerung 5 kommuniziert. Die Gruppensteuerung 5 verfährt die Aufzugskabine 11, 11', 11" nun in dieses Zielstockwerk. Nachdem die Aufzugskabine 11, 11', 11" in dem Zielstockwerk eingefahren ist, werden die Stockwerktür 1, 1', 1" und die Kabinentür der Aufzugskabine 11, 11', 11" geöffnet und der Benutzer kann die Aufzugskabine 11, 11', 11" verlassen.The elevators A, B, C are controlled by the

Das neue Stockwerkterminal 4, 4' ist somit indirekt, das heisst über die Ruferfassungseinheit 40 mit der bestehenden Gruppensteuerung 5 verbunden. Wie in den Ausführungsformen gemäss
Die Ruferfassungseinheit 40 bzw. ein neues Stockwerkterminal 4, 4' weist vorteilhafterweise Schnittstellen zum Abgreifen von Signalen wie Startsignalen, Quittierungssignalen und Zielsignalen auf. Beispielsweise weist eine Ruferfassungseinheit 40 bzw. ein neues Stockwerkterminal 4, 4' eine einfach und rasch erreichbare Schnittstelle auf. Beispielsweise ist eine solche Schnittstelle seitlich aussen an einem Gehäuse der Ruferfassungseinheit 40 bzw. des neuen Stockwerkterminals 4, 4' angebracht. Beliebige Schnittstellen mitbewährten Industrie-Standards wie RS232, USB, FTT10, usw. lassen sich verwenden. Auf diese Weise lassen sich die Signale bei zukünftigen Modernisierungen einfach und rasch abgreifen.The
Sobald nun im Rahmen der Modernisierung der Aufzugsanlage eine neue Gruppensteuerung 6 installiert wird, und mindestens ein Aufzug A, B, C von der bestehenden Gruppensteuerung 5 auf die neue Gruppensteuerung 6 umgehängt wird, so dass der umgehängte Aufzug A, B, C von der neuen Gruppensteuerung 6 angesteuert wird, wird auch die neue Gruppensteuerung 6 zur Kommunikation eines eingegebenen Stockwerkrufs mit der Ruferfassungseinheit 40 verbunden.
Während der Modernisierung kommuniziert die Ruferfassungseinheit 40 also nicht nur mit der alten Gruppensteuerung 5, sondern auch mit der neuen Gruppensteuerung 6. Dies erlaubt eine Verteilung der eingegebenen Stockwerkrufe auf die alte Gruppensteuerung 5 und auf die neue Gruppensteuerung 6. Vorteilhafterweise werden auf dem neuen Stockwerkterminal 4, 4' eingegebene Stockwerkrufe gemäss mindestens einer Regel auf die bestehende Gruppensteuerung 5 und auf die neue Gruppensteuerung 6 verteilt. Vorteilhafterweise wird als Regel eine Zufallsverteilung oder eine alternierende Verteilung oder eine leistungsbezogene Verteilung verwendet. Hierzu weist die Ruferfassungseinheit 40 mindestens einen elektrischen Prozessor mit mindestens einem Datenspeicher auf. Im Datenspeicher ist ein Algorithmus gespeichert, der in den elektrischen Prozessor geladen wird und vom elektrischen Prozessor ausgeführt wird. Der Algorithmus führt diese Regel aus. Beispielsweise weist der Algorithmus einen ersten Parameter P1 auf, der die Anzahl Aufzüge A, B, C der Aufzugsanlage angibt, die von der bestehenden Gruppensteuerung 5 angesteuert werden. Ein zweiter Parameter P2 des Algorithmus gibt die Anzahl Aufzüge A, B, C an, die von der neuen Gruppensteuerung 6 angesteuert werden. Weiter weist der Algorithmus einen dritten Parameter K1 für die Kapazität der bestehenden Gruppensteuerung 5 und einen vierten Parameter K2 für die Kapazität der neuen Gruppensteuerung 6 auf. Ferner führt der Algorithmus eine gezielte Rufzuteilung durch. Der fünfte Parameter Z1 bezeichnet die Rufzuteilung an die bestehende Gruppensteuerung 5 und (Z1-1) bezeichnet die Rufzuteilung an die neue Gruppensteuerung 6. Hieraus folgt eine effektive Transportkapazität TKE:
Für den Fall, dass einer der drei Aufzüge A, B, C zur Modernisierung von der bestehenden Gruppensteuerung 5 abgehängt wird und somit prinzipiell nicht verfügbar ist, und dass ein weiterer der drei Aufzüge A, B, C auf die neue Gruppensteuerung 6 umgehängt wird, folgt: P1=P2=1. Bei einer Kapazität der neuen Gruppensteuerung 6, die 20% über der Kapazität der bestehenden Gruppensteuerung 5 liegt, folgt: K2=1.2*K1.In the event that one of the three elevators A, B, C is relocated from the existing
Eine Zufallsverteilung oder eine alternierenden Verteilung der eingegebenen Stockwerkrufe auf die bestehende Gruppensteuerung 5 und auf die neue Gruppensteuerung 6 entspricht: Z1=(1-Z1)=0.5. Im vorliegenden Fall resultiert dann eine effektive Transportkapazität TKE=1.1.A random distribution or an alternating distribution of the entered floor calls to the existing
Der Algorithmus erlaubt nun eine gezielte Berücksichtigung der höheren Kapazität K2 der neuen Gruppensteuerung 6, in dem an die bestehende Gruppensteuerung 5 eine relativ geringe Rufzuteilung Z1 erfolgt. Für Z1=0.2 resultiert dann eine effektive Transportkapazität TKE=1.16, ein Wert der 6% höher als derjenige der Zufallsverteilung oder der alternierenden Verteilung ist.The algorithm now allows a specific consideration of the higher capacity K2 of the
Die Parameter des Algorithmus lassen sich einfach an die sich ändernde Transportkapazität der Aufzugsanlage während der Modernisierung anpassen.The parameters of the algorithm can easily be adapted to the changing transport capacity of the elevator installation during modernization.
Nach Umhängen des letzten der Aufzüge A, B, C von der bestehenden Gruppensteuerung 5 auf die neue Gruppensteuerung 6 kann die Ruferfassungseinheit demontiert werden.After transferring the last of the elevators A, B, C from the existing
Bei Kenntnis der vorliegenden Erfindung lassen sich vielfältige Variationen des gezeigten Ausführungsbeispiels realisieren. So kann das Gebäude mehr als drei Stockwerke aufweisen, auch kann die Aufzugsanlage aus mehr als drei Aufzügen bestehen. Natürlich lassen sich auch Aufzüge ohne Gegengewichte verwenden.With knowledge of the present invention, various variations of the embodiment shown can be realized. Thus, the building may have more than three floors, and the elevator system may consist of more than three lifts. Of course you can also use elevators without counterweights.
Ebenfalls lassen sich Aufzüge ohne Tragmittel verwenden. Die Antriebe können auch im Aufzugsschacht angeordnet sein. Auch die Gruppensteuerung sowie die Ruferfassungseinheit kann/können in einem beliebigen Raum des Gebäudes angeordnet sein, so dass ein Maschinenraum nicht notwendig ist. Ebenfalls lassen sich Stockwerkterminals mit mehr als zwei Rufknöpfen verwenden. Auch ist es nicht notwendig, dass die Stockwerkterminals Quittierungslampen aufweisen. Die Signalleitungen können parallel oder auch seriell mit der Ruferfassungseinheit verbunden sein.It is also possible to use elevators without suspension elements. The drives can also be arranged in the elevator shaft. The group control and the call detection unit can also be arranged in any room of the building, so that a machine room is not necessary. You can also use floor terminals with more than two call buttons. Nor is it necessary that the floor terminals have acknowledgment lamps. The signal lines may be connected in parallel or else serially with the call detection unit.
