When entering the Elevator car 2 on one floor E1, E2 becomes one Door zone contact 9 actuates the safety contact of the Floor E1, E2 bridges, making the car door and Floor door can be opened early without the safety circuit is interrupted.

    Für die Aufzugssteuerung 4 ist die Position der Aufzugskabine 2 im Aufzugsschacht 1 von Bedeutung. Dafür ist eine Einrichtung zur Erzeugung von Schachtinformation notwendig. Im vorliegenden Beispiel besteht die Einrichtung aus einem über die Schachthöhe gespannten Zahnriemen 10 und aus einem mit dem Zahnriemen 10 in Verbindung stehender Encoder 11, der die absolute Position der Aufzugskabine 2 erfasst. Der an der Aufzugskabine 2 angeordnete Encoder 11 weist ein Zahnrad 12 auf, das beim Verfahren der Aufzugskabine 2 im Aufzugsschacht 1 mittels des Zahnriemens 11 antreibbar ist. Führungsrollen 13 garantieren den sicheren Eingriff des Zahnrades 12 in die Verzahnung des Zahnriemens 10. Der Zahnriemen 10 ist je Ende mittels eines zylindrischen Halters an einem Querträger 14 angeordnet. Weil der Zahnriemen 10 Federeigenschaften aufweist, sind keine zusätzlichen Spannelemente in der Form beispielsweise von Zugfedern zur Montage notwendig. Die Enden des Zahnriemens 10 können je zu einer Kausche geformt werden und mittels einer Klammer mit dem Zahnriemen verbunden werden. Die Kausche umschlingt den am Querträger 14 angeordneten zylindrischen Halter. Der Zahnriemen 10 weist beispielsweise eine Stahlarmierung auf, die dem Zahnriemen 10 die Federeigenschaften verleiht. Ausserdem weist der Zahnriemen 10 eine Farbmarkierung auf, die eine verdrillungsfreie Montage auf Anhieb ermöglicht.For the elevator control 4, the position is Elevator car 2 in elevator shaft 1 is of importance. Therefore is a device for generating shaft information necessary. In the present example, there is the facility from a toothed belt 10 stretched over the shaft height from one connected to the toothed belt 10 Encoder 11, which is the absolute position of the elevator car 2 detected. The encoder 11 arranged on the elevator car 2 has a gear 12, which in the process of Elevator car 2 in elevator shaft 1 by means of the toothed belt 11 can be driven. Guide rollers 13 guarantee the secure engagement of the gear 12 in the toothing of Toothed belt 10. The toothed belt 10 is at each end by means of a cylindrical holder arranged on a cross member 14. Because the timing belt 10 has spring properties no additional clamping elements in the form, for example of tension springs necessary for assembly. The ends of the Timing belts 10 can each be shaped into a thimble and connected to the toothed belt by means of a clip become. The thimble wraps around the cross member 14 arranged cylindrical holder. The toothed belt 10 has For example, a steel reinforcement on the timing belt 10 gives the spring properties. In addition, the Timing belt 10 has a color marking, the one enables twist-free installation right away.

    Anstelle des Zahnriemens 10 ist auch ein Flachriemen mit griffiger Oberfläche möglich, der mit genügend Druck auf einem Pulley des Encoders 11 aufliegt.Instead of the toothed belt 10, there is also a flat belt non-slip surface possible with enough pressure on a pulley of the encoder 11 rests.

    Das Zahnrad 12 des Encoders 11 treibt eine Welle mit einer codierten Scheibe an, deren Code optoelektronisch gelesen wird und die Daten in einem Schieberegister abgelegt werden. Bei einer Umdrehung der Codescheibe von über 360° wiederholt sich die Codierung. Bei langen Verfahrwegen wie derjenige eines Aufzugsschachtes ist zwischen der ersten und einer weiteren Codescheibe ein Reduktionsgetriebe geschaltet, das die weitere Codescheibe in einem bestimmten Verhältnis zur ersten Codescheibe umdrehungsmässig verlangsamt. Weitere Reduktionsgetriebe und Codescheiben können nachgeschaltet sein.The gear 12 of the encoder 11 drives a shaft with a coded disc whose code is read optoelectronically and the data is stored in a shift register become. When the code disk rotates by more than 360 ° the coding is repeated. With long travels like that of an elevator shaft is between the first and another code disk a reduction gear switched that the further code disc in a certain Ratio of rotation to the first code disk slowed down. Further reduction gears and code disks can be downstream.

    Der Datenaustausch mit der Aufzugssteuerung 4 erfolgt derart, dass ein Taktsignal der Aufzugssteuerung 4 an das Schieberegister angelegt wird, wobei das Taktsignal die serielle Datenübertragung zur Aufzugssteuerung 4 steuert. Aus den übertragenen Daten erzeugt die Aufzugssteuerung 4 Fahrparameter der Auf zugskabine 2 wie beispielsweise die absolute Position der Auf zugskabine 2 im Aufzugsschacht 1, die Geschwindigkeit und/oder die Fahrtrichtung der Aufzugskabine 2.The data exchange with the elevator control 4 takes place such that a clock signal of the elevator control 4 to the Shift register is applied, the clock signal being the serial data transmission to elevator control 4 controls. The elevator control 4 generates from the transmitted data Driving parameters of the elevator car 2 such as the absolute position of the elevator car 2 in the elevator shaft 1, the speed and / or the direction of travel of the Elevator car 2.

    Bei Spannungsausfall bleibt die Positionsinformation des Encoders 11 mit der Stellung der Codescheiben erhalten. Weil die Einrichtung zur Erzeugung von Schachtinformation auch für Evakuationsbetrieb verwendet wird, wird der Encoder 11 batteriegestützt betrieben. Falls der Encoder 11 keine oder keine gültigen Fahrparameter erzeugt, beispielsweise bei einem Bruch des Zahnriemens 10, wird die Aufzugskabine sofort angehalten.In the event of a power failure, the position information of the Obtain encoder 11 with the position of the code disks. Because the device for generating shaft information is also used for evacuation operations Encoder 11 operated with battery support. If the encoder 11 no or no valid driving parameters generated, for example, if the toothed belt 10 breaks, the Elevator car stopped immediately.

    Mit der absoluten Positionsinformation des Encoders 11 kann sämtliche nicht sicherheitsrelevante Schachtinformation hergeleitet werden. Wie im gezeigten Beispiel ersichtlich, sind ausser den Sicherheitsschaltern 5,6,9 im Aufzugsschacht 1 keine Schalter notwendig. Beispielsweise wird das Niveau der Stockwerke mittels des Encoders 11 gemessen und der Aufzugssteuerung 4 mitgeteilt. Dazu wird die Aufzugskabine 2 im Aufzugsschacht 1 auf die entsprechenden Niveaus gefahren und die absolute Positionsinformation der Stockwerke der Aufzugssteuerung 4 übertragen.With the absolute position information of the encoder 11 can all shaft information not relevant to safety be derived. As can be seen in the example shown, are in addition to the safety switches 5,6,9 Elevator shaft 1 no switches required. For example the level of the floors is determined by means of the encoder 11 measured and communicated to the elevator control 4. This will the elevator car 2 in the elevator shaft 1 on the appropriate levels and the absolute Position information of the floors of the elevator control 4 transfer.
