Description

Die Erfindung betrifft ein Verfahren zur Absicherung der Kabine eines Aufzuges gegen unbeabsichtigte Bewegung.The invention relates to a method for protecting the cabin of an elevator against unintentional movement.

Aus dem Stand der Technik ist ein Verfahren bekannt, bei dem die Kabine eines Aufzugs gegen unbeabsichtigte Bewegung abgesichert ist. Bei diesem bekannten Verfahren wird um die regulären Haltepositionen der Kabine an den entsprechenden Haltestellen ein sogenannte Entriegelungszone eingerichtet in welcher die Kabine unter bestimmten Bedingungen mit bestimmten Geschwindigkeiten mit entriegelten Türen fahren darf. Dabei wird ein Not-Stopp der Kabine eingeleitet, wenn die Kabine mit entriegelten Türen ausserhalb der Entriegelungszonen oder innerhalb der Entriegelungszonen sich schneller als mit den bestimmten Bedingungen bewegt. Dies hat den Vorteil, dass die Türen des Aufzugs für die Passagiere in sicherer Weise schon kurz vor dem Halt geöffnet werden können und ebenso ein möglicherweise nötiges Nachstellen der Höhenposition des Kabinenbodens nach dem Halt bei geöffneten Türen erfolgen kann und dennoch die Kabine nie undefiniert mit geöffneten Türen fährt.A method is known from the prior art in which the car of an elevator is secured against unintentional movement. In this known method, a so-called unlocking zone is set up around the regular stopping positions of the car at the corresponding stops, in which the car may travel under certain conditions at certain speeds with the doors unlocked. An emergency stop of the car is initiated if the car with unlocked doors moves outside the unlocking zones or inside the unlocking zones faster than the specified conditions. This has the advantage that the doors of the elevator can be opened safely for the passengers shortly before the stop and a possibly necessary readjustment of the height position of the car floor can also be carried out after the stop with the doors open and yet the car can never be undefined with the doors open doors.

Aus der US 2018/201479 A1 ist ein Verfahren bekannt, in dem für Wartungsarbeiten außerhalb der regulären Entriegelungszonen der Sicherheitsmechanismus der Kabinentür ausgeschaltet wird, so dass die Kabine außerhalb der Entriegelungszonen mit entriegelter Kabinentür bewegt werden kann. Nach der Wartung wird der Sicherheitsmechanismus wieder aktiviert.From the U.S. 2018/201479 A1 a method is known in which the safety mechanism of the car door is switched off for maintenance work outside the regular unlocking zones, so that the car can be moved outside the unlocking zones with the car door unlocked. After maintenance, the safety mechanism is reactivated.

Die JP S56 33369 A betrifft ein Verfahren, bei dem eine Aufzugskabine im Falle eines Stromausfalls eine Stockwerkebene anfährt, welche sich innerhalb einer bestimmten Entfernung von der Kabine befindet. Die vorherige Fahrtrichtung der Aufzugskabine ist dabei unerheblich.The JP S56 33369 A relates to a method in which, in the event of a power failure, an elevator car moves to a floor level which is within a certain distance of the car. The previous direction of travel of the elevator car is irrelevant.

Es ist Aufgabe der Erfindung, ein verbessertes Verfahren bereit zu stellen.It is the object of the invention to provide an improved method.

Diese Aufgabe wird, ausgehend von einem Verfahren der eingangs genannten Art, durch ein Verfahren nach Anspruch 1 und einer Aufzugssteuerung nach Anspruch 9 gelöst.Based on a method of the type mentioned above, this object is achieved by a method according to claim 1 and an elevator control according to claim 9 .

Vorteilhafte Ausgestaltungen sind in den weiteren abhängigen Ansprücher angegeben.Advantageous refinements are specified in the further dependent claims.

Das erfindungsgemäße Verfahren ist ein Verfahren zur Absicherung der Kabine eines Aufzugs welcher zur Ausbildung von regulären Entriegelungszonen im Bereich um die vorgesehenen Haltestellen an den Stockwerken vorgesehen ist gegen unbeabsichtigte Bewegung. Das Verfahren überwacht die Geschwindigkeit der Kabine, die Höhenposition der Kabine im Aufzugsschacht und den Status der Türverriegelung der Kabinentür und identifiziert einen möglichen Halt der Kabine, die Höhenposition der Kabine ausserhalb einer regulären Entriegelungszone und einen möglicherweise entriegelten Zustandes der Kabinentüre. Ein erstes Teilverfahren des Verfahrens bildet eine temporäre Entriegelungszone aus, wenn die Kabine ausserhalb einer regulären Entriegelungszone mit entriegelter Kabinentüre hält und weisst der temporären Entriegelungszone eine obere und eine untere Grenze über und unterhalb der Position des Halts der Kabine zu.The method according to the invention is a method for protecting the car of an elevator, which is provided for the formation of regular unlocking zones in the area around the intended stops on the floors, against unintentional movement. The method monitors the speed of the car, the height position of the car in the hoistway and the status of the car door lock and identifies a possible stop of the car, the height position of the car outside a regular unlocking zone and a possible unlocked status of the car door. A first sub-method of the method establishes a temporary unlocking zone when the car stops outside a regular unlocking zone with the car door unlocked and assigns the temporary unlocking zone an upper and a lower limit above and below the position of the car's stop.

Erfindungsgemäß weist das Teilverfahren der temporären Entriegelungszone eine maximal zulässige Fahrgeschwindigkeit für die Kabine innerhalb der temporären Entriegelungszone zu.According to the invention, the sub-method assigns the temporary unlocking zone a maximum permissible driving speed for the car within the temporary unlocking zone.

Dies kann den Vorteil ausbilden, dass der Aufzug nach einem Halt gegen unbeabsichtigte Bewegung gesichert werden kann, wenn sich die Kabine nicht im Bereich einer im Speicher der Aufzugsteuerung hinterlegten regulären Entriegelungszone befindet. Dies kann die Sicherheit des Aufzuges erhöhen.This can form the advantage that the elevator can be secured against unintentional movement after a stop if the car is not in the area of a regular unlocking zone stored in the memory of the elevator control. This can increase the safety of the elevator.

Mit Kabine ist der Fahrkorb des Aufzugs gemeint. Der Begriff Kabinentüre bezeichnet auch den Plural. Entriegelt meint, dass mindestens eine Kabinentüre entriegelt ist. Verriegelt meint, dass alle Kabinentüren verriegelt sind. Bei Aufzügen ohne Verriegelungsmöglichkeit meint verriegelt geschlossen und entriegelt geöffnet. Mit entriegelt ist ein entriegelter Zustand mindestens einer Kabinentüre gemeint unabhängig davon ob die Kabinentüre geöffnet oder geschlossen ist. Mit Haltestelle ist die Bodenebene der zum Halten angefahrenen Haltestelle eines Stockwerkes gemeint. Eine Entriegelungszone ist der Bereich unterhalb und oberhalb eines Halts der Kabine, in dem sich der Boden des Fahrkorbs zu befinden hat, damit die Schachttür an dieser Haltestelle entriegelt werden darf. Eine reguläre Entriegelungszone ist eine in einem Speicher der Aufzugssteuerung gespeicherte Entriegelungszone um eine Haltestelle. Eine temporäre Entriegelungszone ist eine Entriegelungszone ausserhalb von im Speicher der Aufzugssteuerung gespeicherten regulären Entriegelungszonen. Alle Positionen der Kabine beziehen sich stets auf die Bodenebene der Kabine. Unbeabsichtigte Bewegung ist eine Bewegung oder Fahrt der Kabine, welche dem vorgesehenen Verhalten des Aufzuges wiederspricht und insbesondere geltenden Vorschriften zum Betrieb des Aufzuges widerspricht. Die hier und in der Folge genannten Minimal- und Maximalwerte können länderspezifischen, gesetzlichen Vorgaben und insbesondere entsprechenden Normen entspringen.Cabin means the car of the elevator. The term cabin door also designates the plural. Unlocked means that at least one cabin door is unlocked. Locked means that all cabin doors are locked. For elevators without a locking option, locked means closed and unlocked means open. Unlocked means an unlocked state of at least one car door, regardless of whether the car door is open or closed. Stop means the floor level of the stop on a floor that is used to stop. An unlocking zone is the area below and above a stop of the car where the floor of the car has to be in order for the landing door to be unlocked at that stop. A regular unlocking zone is an unlocking zone around a stop stored in a memory of the elevator controller. A temporary unlocking zone is an unlocking zone outside of regular unlocking zones stored in the memory of the elevator controller. All positions of the cabin always refer to the floor level of the cabin. Unintentional movement is a movement or movement of the car that contradicts the intended behavior of the elevator and in particular the applicable regulations for the operation of the elevator contradicts. The minimum and maximum values specified here and in the following may arise from country-specific, legal requirements and, in particular, corresponding standards.

Vorzugsweise ist für das Verfahren ein zweites Teilverfahren vorgesehen, welches bei Überfahren der Kabine der oberen oder der unteren Grenze der temporären Entriegelungszone mit entriegelter Kabinentüre eine Alarmreaktion, insbesondere einen Not-Stopp, insbesondere einen aktiv gebremsten Not-Stopp der Kabine einleitet. Dies kann den Vorteil ausbilden, dass die Kabine nach unbeabsichtigter Bewegung zuverlässig zum Halten gebracht wird. Dies kann die Sicherheit der Passagiere der Kabine erhöhen.A second partial method is preferably provided for the method, which initiates an alarm reaction, in particular an emergency stop, in particular an actively braked emergency stop of the cabin, when the cabin exceeds the upper or lower limit of the temporary unlocking zone with the cabin door unlocked. This can form the advantage that the car is reliably brought to a halt after an unintentional movement. This can increase the safety of the passengers in the cabin.

Eine Alarmreaktion ist ein Signal oder eine Massnahme. Ein Not-Stopp ist ein Halt der Kabine durch Unterbrechung der Stromzufuhr für den Antrieb durch Öffnen des Sicherheitskreises oder ein aktiv gebremster Not-Stopp. Ein aktiv gebremster Not-Stopp ist ein Halt der Kabine durch aktives Bremsen der Kabine durch eine Antriebsbremse, Seilbremse, Kabinenbremse oder sonstige Bremseinrichtung. Vorzugsweise verhindert das zweite Teilverfahren einen Not-Stopp der Kabine aufgrund der Fahrt der Kabine mit entriegelter Kabinentüre ausserhalb einer regulären Entriegelungszone, wenn die Kabine mit entriegelter Kabinentüre sich innerhalb einer temporären Entriegelungszone befindet und die der temporären Entriegelungszone zugewiesene maximal zulässigen Fahrgeschwindigkeit nicht überschreitet.An alarm reaction is a signal or an action. An emergency stop is a stop of the car by interrupting the power supply to the drive by opening the safety circuit or an actively braked emergency stop. An actively braked emergency stop is a stop of the car by actively braking the car with a drive brake, cable brake, car brake or other braking device. The second sub-method preferably prevents an emergency stop of the cabin due to the cabin traveling with the cabin door unlocked outside a regular unlocking zone if the cabin with the cabin door unlocked is within a temporary unlocking zone and does not exceed the maximum permissible driving speed assigned to the temporary unlocking zone.

Dies kann den Vorteil ausbilden, dass die Kabine bei einem Halt ausserhalb der regulären Haltestellen in geordneter Weise bewegt werden kann um etwa den Passagieren einen Notausstieg zu ermöglichen. Dies kann die Sicherheit der Passagiere der Kabine erhöhen.This can form the advantage that the car can be moved in an orderly manner when stopping outside the regular stops, for example to enable the passengers to exit in an emergency. This can increase the safety of the passengers in the cabin.

Vorzugsweise leitet das zweite Teilverfahren einen Not-Stopp der Kabine ein, wenn die Kabine mit entriegelter Kabinentüre sich innerhalb einer temporären Entriegelungszone befindet und die der temporären Entriegelungszone zugewiesene maximal zulässigen Fahrgeschwindigkeit überschreitet. insbesondere ist dieser Not-Stopp kein aktiv gebremster Not-Stopp. Insbesondere ist dieser Not-Stopp ein Not-Stopp der durch das Öffnen des Sicherheitskreises des Aufzugs herbeigeführt wird und so die Stromzufuhr des Antriebs unterbricht.The second sub-method preferably initiates an emergency stop of the car if the car with unlocked car door is within a temporary unlocking zone and exceeds the maximum permissible driving speed assigned to the temporary unlocking zone. in particular, this emergency stop is not an actively braked emergency stop. In particular, this emergency stop is an emergency stop that is brought about by opening the safety circuit of the elevator and thus interrupting the power supply to the drive.

Dies kann den Vorteil ausbilden, dass die Kabine bei geordneter Fahrt nach einem Halt ausserhalb der regulären Haltestellen zuverlässig zum Halten gebracht wird, wenn diese Fahrt ausser Kontrolle gerät in dem sie zu viel Geschwindigkeit aufnimmt. Dies kann die Sicherheit der Passagiere der Kabine erhöhen.This can develop the advantage that the car is reliably brought to a halt when the car is traveling in an orderly manner after stopping outside the regular bus stops if this journey gets out of control by picking up too much speed. This can increase the safety of the passengers in the cabin.

Vorzugsweise legt das erste Teilverfahren die Werte der temporären Entriegelungszone in einem Speicher der Aufzugssteuerung ab.The first partial method preferably stores the values of the temporary unlocking zone in a memory of the elevator control.

Dies kann den Vorteil ausbilden, dass die Aufzugssteuerung die Wirkungen der temporären Entriegelungszone entsprechend zuweisen und umsetzen kann.This can develop the advantage that the elevator control can assign and implement the effects of the temporary unlocking zone accordingly.

Vorzugsweise hebt das erste Teilverfahren die temporäre Entriegelungszone wieder auf, wenn die Kabinentüre wieder verriegelt sind. Die temporäre Entriegelungszone kann auch durch einen entsprechenden Reset zur Aufhebung der temporären Entriegelungszone aufgehoben werden.The first partial method preferably cancels the temporary unlocking zone again when the car doors are locked again. The temporary unlock zone can also be canceled by a corresponding reset to cancel the temporary unlock zone.

Dies kann den Vorteil ausbilden, dass der Aufzug schnellstmöglich wieder in einen regulären Zustand erreicht, um die Fahrt etwa zu einer regulären Haltestelle fortzusetzen. Dies kann die Sicherheit und den Komfort der Passagiere erhöhen.This can develop the advantage that the elevator returns to a regular state as quickly as possible in order to continue the journey to a regular stop, for example. This can increase passenger safety and comfort.

Die Verriegelung der Kabinentüre kann durch einen Sensor detektiert sein, der den Verriegelungszustand der Kabinentüre an die Aufzugssteuerung übermittelt. Die Aufhebung der temporären Entriegelungszone bedeutet, dass die beschriebenen Wirkungen der Entriegelungszone entfallen.The locking of the car door can be detected by a sensor that transmits the locking status of the car door to the elevator control. The cancellation of the temporary unlocking zone means that the described effects of the unlocking zone no longer apply.

Vorzugsweise liest das zweite Teilverfahren die Werte der temporären Entriegelungszone aus einem Speicher der Aufzugssteuerung aus.The second partial method preferably reads the values of the temporary unlocking zone from a memory in the elevator control.

Vorzugsweise hebt das zweite Teilverfahren einen Not-Stopp der Kabine aufgrund einer temporären Entriegelungszone wieder auf, wenn die Kabinentüre wieder verriegelt sind. Der genannte Not-Stopp kann auch durch einen entsprechenden Reset zur Aufhebung des Not-Stopps aufgehoben werden.The second sub-method preferably cancels an emergency stop of the car due to a temporary unlocking zone when the car doors are locked again. Said emergency stop can also be canceled by a corresponding reset to cancel the emergency stop.

Dies kann den Vorteil ausbilden, dass der Aufzug schnellstmöglich wieder in Fahrbereitschaft versetzt wird um etwa nötige Justierung in seiner Höhe zu ermöglichen.This can develop the advantage that the elevator is put back into operation readiness as quickly as possible in order to enable any necessary adjustment in its height.

Vorzugsweise weist das Verfahren ein drittes Teilverfahren auf, welches die Höhenpositionen von regulären Haltestellen insbesondere während einer Einlernphase, insbesondere während einer Einlernfahrt einlernt und insbesondere in einem Speicher ablegt. Vorzugsweise bildet das dritte Teilverfahren um die Höhenpositionen der regulären Haltestellen in bestimmtem, insbesondere vorgegebenem Abstand reguläre Entriegelungszonen aus und legt deren obere und untere Grenzen in einem Speicher der Aufzugssteuerung ab.The method preferably has a third sub-method, which learns the height positions of regular bus stops, in particular during a learning phase, in particular during a learning journey, and in particular stores them in a memory. The third partial method preferably forms regular unlocking zones around the height positions of the regular stops at a specific, in particular predetermined distance, and stores their upper and lower limits in a memory of the elevator control.

Dies kann den Vorteil ausbilden, dass die Aufzugssteuerung die regulären und temporären Entriegelungszonen in ähnlicher oder gleicher weise behandelt. Dies kann die Steuerung vereinfachen und deren Sicherheit erhöhen.This can form the advantage that the elevator control handles the regular and temporary unlocking zones in a similar or the same way. This can simplify the control and increase its safety.

Vorzugsweise führt das Verfahren das erste Teilverfahren vor einer Einlernphase und/oder während einer Einlernfahrt aus.The method preferably carries out the first sub-method before a learning phase and/or during a learning journey.

Dies kann den Vorteil ausbilden, dass die Aufzugsteuerung ein zutreffendes Modell des Aufzuges samt der Positionen der regulären Haltestellen und regulären Entriegelungszonen erzeugt.This can have the advantage that the elevator controller creates an accurate model of the elevator, including the positions of the regular landings and regular unlocking zones.

Dies kann die Effizienz der Aufzugssteuerung und die Sicherheit des Aufzugs erhöhen.This can increase elevator control efficiency and elevator safety.

Vor der Einlernphase sind noch keine regulären Entriegelungszonen in einem Speicher der Aufzugssteuerung hinterlegt. Während der Einlernphase oder während der Einlernfahrt sind die regulären Entriegelungszonen noch nicht vollständig in einem Speicher der Aufzugsteuerung hinterlegt. Insbesondere berücksichtigt die Aufzugsteuerung nicht in ihrem Speicher hinterlegte reguläre Entriegelungszonen nicht. Vorzugsweise führt das Verfahren das erste Teilverfahren auch während einer Evakuierung der Kabine ausserhalb einer regulären Entriegelungszonen durch. Insbesondere befindet sich die Kabine bei einer Evakuierung mindestens teilweise im Bereich zwischen den regulär vorgesehenen Stockwerken. Vorzugsweise führt das Verfahren das erste Teilverfahren auch bei fehlerhaft gespeicherten regulären Haltestellen aus.Before the learning phase, no regular unlocking zones are stored in a memory of the elevator control. During the learning phase or during the learning journey, the regular unlocking zones are not yet completely stored in a memory of the elevator control. In particular, the elevator control does not take into account those stored in its memory regular unlock zones do not. The method preferably also carries out the first sub-method while the cabin is being evacuated outside of a regular unlocking zone. In particular, during an evacuation, the cabin is located at least partially in the area between the floors normally provided. The method preferably also carries out the first sub-method in the case of erroneously stored regular stops.

Detaillierte Beschreibung der Zeichnungen:
Fig. 1 zeigt das Diagramm einer Entriegelungszone.Detailed description of the drawings:
1 shows the diagram of an unlocking zone.

Die Achse 11 zeigt die mögliche Höhenposition der Kabine eines Aufzugs um eine Haltestelle 23. Die Haltestelle ist umgeben von einer Entriegelungszone mit einer oberen Grenze der Entriegelungszone 21 und einer unteren Grenze der Entriegelungszone. Innerhalb der Entriegelungszone darf die Kabine unter bestimmten Voraussetzungen mit entriegelten Türen fahren. Die Achse 12 zeigt die Geschwindigkeit einer Kabine eines Aufzugs im Bereich einer Entriegelungszone und weist verschiedene Geschwindigkeitsbarrieren 31, 33, und 34 auf.The axis 11 shows the possible height position of the car of an elevator around a landing 23. The landing is surrounded by an unlocking zone with an upper limit of the unlocking zone 21 and a lower limit of the unlocking zone. Within the unlocking zone, the cabin may, under certain conditions, drive with the doors unlocked. The axis 12 shows the speed of a car of an elevator in the area of an unlocking zone and has various speed barriers 31, 33 and 34.

Der Nullpunkt der Geschwindigkeit 31 entspricht einem Stillstand der Kabine. Die maximal zulässige Einfahrgeschwindigkeit 34 legt die maximal zulässige Geschwindigkeit der Kabine mit entriegelten Türen in der Entriegelungszone fest. Die maximal zulässige Nachstellgeschwindigkeit 33 legt die maximal zulässige Geschwindigkeit der Kabine in der Entriegelungszone nach einem Halt mit entriegelten Türen bis zu Wieder-Verriegelung der Türen fest.The zero point of the speed 31 corresponds to a standstill of the car. The maximum allowable entry speed 34 defines the maximum allowable speed of the car with the doors unlocked in the unlock zone. The maximum permissible adjustment speed 33 defines the maximum permissible speed of the car in the unlocking zone after a stop with the doors unlocked until the doors are locked again.

Der Geschwindigkeitsverlauf 13 einer anhaltenden der Kabine zeigt einen Eintritt der Kabine in die Entriegelungszone (21, 22) an der oberen Grenze der Entriegelungszone 21 mit einer Geschwindigkeit unterhalb der maximal zulässigen Einfahrgeschwindigkeit 34. Nach dem Eintritt in die Entriegelungszone (21, 22) werden die Türen entriegelt und beginnen sich zu öffnen. Der Geschwindigkeitsverlauf 13 der Kabine verläuft weiterhin unterhalb der Einfahrgeschwindigkeit 34 bis zum Stillstand im Bereich der Haltestelle 23. Nach dem Stillstand kann die Position der Kabine mit einer Geschwindigkeit unterhalb der maximal zulässige Nachstellgeschwindigkeit 33 nachgestellt werden. Nach dem Schliessen und Verriegeln der Türe zur Abfahrt verläuft der Geschwindigkeitsverlauf 13 unabhängig von der maximal zulässigeThe speed curve 13 of a sustained cabin shows the cabin entering the unlocking zone (21, 22) at the upper limit of the unlocking zone 21 at a speed below the maximum permissible entry speed 34. After entering the unlocking zone (21, 22), the Doors unlock and begin to open. The speed profile 13 of the car continues to run below the entry speed 34 until it comes to a standstill in the area of the bus stop 23. After the standstill, the position of the car can also be adjusted be readjusted at a speed below the maximum permissible readjustment speed 33 . After closing and locking the exit door, the speed profile 13 runs independently of the maximum permissible

Nachstellgeschwindigkeit 33 und der maximal zulässige Einfahrgeschwindigkeit 34.Readjustment speed 33 and the maximum permissible run-in speed 34.

Innerhalb einer Entriegelungszone (21, 22) ist bei entriegelten Türen die maximale Einfahrgeschwindigkeit 34 gleich 0,8 m/s (5.12.1.4.c) und die maximale Nachstellgeschwindigkeit gleich 0,3 m/s (5.12.1.4.d) wobei ansonsten ein Not-Stop (5.6.7.1) mit bestimmten Bedingungen zum Ort des darauf folgenden Halts (5.6.7.5) eingeleitet werden muss. Eine Entriegelungszone hat eine maximale Ausdehnung von 20 cm unter und über der Haltestelle bei nicht gemeinsam angetriebenen Kabinen- und Schachttüren und von 35 cm bei gemeinsam angetriebenen Kabinen- und Schachttüren. Das bedeutet, dass die obere und die untere Grenze der Entriegelungszone jeweils eine Entfernung von 20 cm beziehungsweise 35 cm von der Haltestelle aufweisen.Within an unlocking zone (21, 22), when the doors are unlocked, the maximum entry speed 34 is 0.8 m/s (5.12.1.4.c) and the maximum adjustment speed is 0.3 m/s (5.12.1.4.d), with otherwise an emergency stop (5.6.7.1) with certain conditions for the location of the subsequent stop (5.6.7.5) must be initiated. An unlocking zone has a maximum extension of 20 cm below and above the landing for non-jointly powered car and landing doors and 35 cm for commonly powered car and landing doors. This means that the upper and lower limits of the unlocking zone are 20 cm and 35 cm from the bus stop, respectively.

Bei bekannten Aufzügen sind die Entriegelungszonen um die vorgesehen regulären Haltestellen an den Stockwerken herum im Allgemeinen vordefiniert etwas durch entsprechende mechanische Markierungen im Schacht oder durch in einem elektrischen Speicher der Aufzugssteuerung gespeicherte Höhenpositionen für die entsprechenden Grenzen der Entriegelungszonen.In known elevators, the unlocking zones around the intended regular landing stops are generally predefined somewhat by corresponding mechanical markings in the shaft or by height positions stored in an electrical memory of the elevator control for the corresponding boundaries of the unlocking zones.

Das erfindungsgemässe Verfahren kommt vor allem dann zur Wirkung, wenn sich aus irgendeinem Grund ein Halt der Kabine ausserhalb der vordefinierten regulären Entriegelungszonen ereignet. Dies ist denkbar etwa bei der Inbetriebnahme des Aufzuges vor oder während der Einlernphase zur Festlegung der Stockwerkspositionen und der entsprechenden regulären Entriegelungszonen, wenn vor oder während der Einlernphase die regulären Entriegelungszonen noch nicht definiert und im Speicher der Aufzugssteuerung hinterlegt sind, oder etwa bei einem Halt, Not-Stopp oder Evakuierungsfall zwischen den Stockwerken.The method according to the invention comes into effect above all when, for some reason, the car stops outside the predefined regular unlocking zones. This is conceivable, for example, when the elevator is commissioned before or during the learning phase to determine the floor positions and the corresponding regular unlocking zones, if the regular unlocking zones are not yet defined and stored in the memory of the elevator control before or during the learning phase, or for example at a stop, Emergency stop or evacuation case between floors.

Wenn in einer so gearteten Situation die Kabine nicht in einer regulären Entriegelungszone zum Stehen kommt und/oder ausserhalb einer regulären Entriegelungszone die Türen der Kabine entriegelt werden sollen, dann wäre die Kabine nicht gegen unbeabsichtigte oder zu schnelle Bewegung gesichert.If, in such a situation, the car does not come to a stop in a regular unlocking zone and/or outside a regular unlocking zone the doors of the car should be unlocked, then the cabin would not be secured against unintentional or excessively rapid movement.

Daher sieht das erfindungsgemässe Verfahren vor, dass auch unabhängig von regulären Haltestellen der Stockwerke beim Halt der Kabine und/oder beim Entriegeln der Kabinentüre ausserhalb von regulären Entriegelungszonen der regulären Haltestellen temporäre Entriegelungszonen ausgebildet werden.The method according to the invention therefore provides for temporary unlocking zones to be formed outside of regular unlocking zones of the regular stops, also independently of regular stops on the floors when the car stops and/or when the car door is unlocked.

Sobald ein Halt und/oder eine Entriegelung der Kabinentüre ausserhalb der regulären Entriegelungszonen detektiert wird, wird sofort um die Position des Ereignisses eine temporäre Entriegelungszone eingerichtet. Die Position des Ereignisses wird hierbei temporär als Haltestelle angesehen. Die temporäre Entriegelungszone kann bei einem Aufzug mit permanenter und durchgehender Detektion der Höhenposition dadurch eingerichtet werden, dass einem Speicher der Aufzugssteuerung die Werte für die obere und untere Entriegelungszone oder der Wert der Position des Halts zugewiesen wird, während die Aufzugssteuerung die relative Ausdehnung fest gespeichert vorgegeben hat.As soon as a stop and/or an unlocking of the car door outside the regular unlocking zones is detected, a temporary unlocking zone is set up immediately around the position of the event. The position of the event is temporarily regarded as a stop. The temporary unlocking zone can be set up in an elevator with permanent and continuous detection of the height position by assigning the values for the upper and lower unlocking zone or the value of the position of the stop to a memory of the elevator control, while the elevator control specifies the relative extent in a permanently stored manner has.

Die temporäre Entriegelungszone wird solange aufrechterhalten, bis die Kabinentüre wieder verriegelt sind. Nach der Aufhebung der Entriegelungszone entfallen deren Wirkungen. Die Aufhebung der temporären Entriegelungszone kann durch Löschen der Werte für die obere und untere Grenze der temporären Entriegelungszone erfolgen.The temporary unlocking zone is maintained until the car doors are locked again. After canceling the unlock zone, its effects are gone. Overriding the temporary unlock zone can be done by clearing the upper and lower limit values of the temporary unlock zone.

Ist eine temporäre Entriegelungszone eingerichtet in der sich das Bodenniveau der Kabine befindet und überschreiet die Geschwindigkeit der Bewegung die entsprechenden Grenzwerte oder fährt die Kabine mit entriegelter Kabinentüre über die Grenzen der Entriegelungszone hinaus, so führt das Verfahren einen Not-Stopp der Kabine durch. Der Not-Stopp kann durch das Öffnen des Sicherheitskreises des Aufzuges herbeigeführt werden, der den Motorantrieb unterbricht und/oder die Bremsen an der Kabine aktiviert. Der Not-Stopp kann durch einen entsprechenden Resett des Aufzuges wieder deaktiviert werden.If a temporary unlocking zone is set up in which the floor level of the car is located and the speed of the movement exceeds the corresponding limit values or the car moves beyond the limits of the unlocking zone with the car door unlocked, the procedure carries out an emergency stop of the car. The emergency stop can be effected by opening the elevator's safety circuit, which interrupts the motor drive and/or activates the brakes on the car. The emergency stop can be deactivated again by a corresponding reset of the lift.
