Description

AUFZUGSANLAGE UND AUFZUGSTÜRSTEUERUNG VERFAHREN ELEVATOR SYSTEM AND ELEVATOR DOOR CONTROL PROCEDURE
Die Erfindung betrifft eine Aufzugsanlage mit einer Schachttürsteuereinheit, welche unmittelbar eine Schachttürverriegelvorrichtung zur Entriegelung und/oder Öffnung und/oder Schliessung dieser Schachttür steuern kann. The invention relates to an elevator installation with a shaft door control unit which can directly control a shaft door locking device for unlocking and/or opening and/or closing this shaft door.
Aufzugsanlagen umfassen üblicherweise eine in einem Aufzugsschacht verfahrbare eine Kabinentür aufweisende Aufzugskabine. An der Aufzugskabine ist ein Kabinentürantrieb angeordnet, welcher zur Öffnung und Schliessung der Kabinentür vorgesehen ist. Der Aufzugsschacht weist darüber hinaus mehrere übereinander angeordnete Türöffnungen auf, an welcher jeweils eine Schachttür angeordnet ist. Stoppt die Aufzugskabine an einer dieser Schachttüren bzw. ist an dieser angeordnet, wird üblicherweise mittels einer an der Kabinentür vorgesehenen Kopplungseinrichtung die Kabinentür mit der Schachttür mechanisch gekoppelt. Demnach wird die Schachttür passiv entriegelt/geöffnet/geschlossen. Das heisst, dass sowohl die Kabinentür als auch die Schachttür ausschliesslich mittels des Kabinentürantrieb entriegelt/geöffhet/geschlossen wird. Diese Herangehensweise war vorgeblich dadurch bestimmt, dass bei Schachttüren keine Steuerelektronik angebracht war und eine aktive Entriegelung der Schachttür so ausgeschlossen war. Das Anbringen von Steuerelektronik an jeder der Schachttüren hätte die Kosten für die Aufzugsanlage unangemessen erhöht. Elevator systems usually include an elevator car that can be moved in an elevator shaft and has a car door. A car door drive, which is provided for opening and closing the car door, is arranged on the elevator car. The elevator shaft also has a plurality of door openings arranged one above the other, on each of which a shaft door is arranged. If the elevator car stops at one of these shaft doors or is arranged on this, the car door is usually mechanically coupled to the shaft door by means of a coupling device provided on the car door. Accordingly, the landing door is unlocked/opened/closed passively. This means that both the car door and the shaft door are unlocked/opened/closed exclusively by means of the car door drive. This approach was allegedly determined by the fact that no control electronics were attached to the landing doors and an active unlocking of the landing door was therefore impossible. Attaching control electronics to each of the landing doors would have unduly increased the cost of the elevator system.
Aufgrund technologischer Weiterentwicklung von Elektronik und Antrieben, insbesondere von Kommunikationselektronik und Elektromotoren, ist eine kosteninteressante Lösung ermöglicht, dass sowohl die Kabinentür als auch Schachttür eine Verriegelvorrichtung ausschliesslich zum Entriegeln/Öffnen/Schliessen der jeweiligen Tür umfasst. Demnach sind die Anforderungen an eine mechanisch anfällige Kopplung, welche die vom Kabinentürantrieb erwirkte Öffnungsbewegung die Schachttür entriegelt/öffhet/schliesst reduziert. Dennoch muss sichergestellt werden, dass sowohl die Kabinentür als auch die Schachttür lediglich dann eine Öffnungsbewegung vollführen kann, wenn die Kabinentür an der Schachttür angeordnet ist und die Aufzugskabine bei sowohl geöffneter Schachttür als auch geöffneter Kabinentür vom Stockwerk betretbar ist. Due to further technological development of electronics and drives, in particular of communication electronics and electric motors, a cost-effective solution is made possible in that both the car door and the landing door include a locking device exclusively for unlocking/opening/closing the respective door. Accordingly, the requirements for a mechanically susceptible coupling, which unlocks/opens/closes the opening movement brought about by the car door drive, are reduced. Nevertheless, it must be ensured that both the car door and the shaft door can only perform an opening movement when the car door is arranged on the shaft door and the elevator car can be entered from the floor with both the shaft door and the car door open.
Aufgabe der Erfindung ist es daher, eine Aufzugsanlage zu entwickeln, welche ein notwendiges Mass an Sicherheit ermöglicht, wenn die Schachttür durch eine eigens an der Schachtür angeordnete Schachttürverriegelvorrichtung entriegelbar bzw. öffenbar bzw. schliessbar ist. The object of the invention is therefore to develop an elevator system which a necessary level of security if the shaft door can be unlocked or opened or closed by a shaft door locking device specially arranged on the shaft door.
Die Aufgabe wird gelöst durch eine Aufzugsanlage mit einer in einem Aufzugsschacht verfahrbaren Aufzugskabine, einer an der Aufzugskabine angeordneten Kabinentür, wenigstens einer an einer Türöffnung des Aufzugsschachtes angeordneten Schachttür, einer Schachttürverriegelvorrichtung, insbesondere umfassend einen Schachttürantrieb (13), zur Entriegelung/Schliessung/Öffhung der Schachttür, einem an der Schachttür angeordneten Schachttürsensor und einem an der Kabinentür angeordneten Kabinentürsignalgeber, und eine mit dem Schachttürsensor wirkverbundene Schachttürsteuereinheit, durch welche Schachttürsteuereinheit der Schachttürverriegelvorrichtung unmittelbar ansteuerbar ist bei Empfang eines Kabinentürsignales des Kabinentürsignalgebers durch den Schachttürsensor. The object is achieved by an elevator system with an elevator car that can be moved in an elevator shaft, a car door arranged on the elevator car, at least one shaft door arranged on a door opening of the elevator shaft, a shaft door locking device, in particular comprising a shaft door drive (13), for unlocking/closing/opening the Shaft door, a shaft door sensor arranged on the shaft door and a car door signal transmitter arranged on the car door, and a shaft door control unit which is operatively connected to the shaft door sensor and which shaft door control unit can directly control the shaft door locking device when the shaft door sensor receives a car door signal from the car door signal transmitter.
Die Aufgabe wird ebenso gelöst mittels eines Verfahrens zur Steuerung einer eine Kabinentür und eine Schachttür umfassenden Aufzugsanlage, umfassend die folgenden Verfahrensschritte: The object is also achieved by means of a method for controlling an elevator system that includes a car door and a shaft door, including the following method steps:
- Generieren eines Kabinentürsignals mittels eines an der Kabinentür angeordneten Kabinentürsignalgebers, - generating a car door signal by means of a car door signal generator arranged on the car door,
- Empfangen des Kabinentürsignals mittels eines an der Schachttür angeordneten Schachttürsensors, wobei der Empfang des Kabinentürsignals die Anwesenheit der Kabinentür an der Schachttür bestätigt, - receiving the car door signal by means of a shaft door sensor arranged on the shaft door, the receipt of the car door signal confirming the presence of the car door at the shaft door,
- Übermitteln des Kabinentürsignals an eine Schachttürsteuereinheit zum Entriegeln/Öffhen/Schliessen der Schachttür, - Transmission of the car door signal to a landing door control unit for unlocking/opening/closing the landing door,
- unmittelbares Ansteuem einer Schachttürverriegelvorrichtung, insbesondere eines Schttürantriebs der Schachttürverriegelvorrichtung durch die Schachttürsteuereinheit zum Entriegeln/Öffnen/Schliessen der Schachttür bei Vorhandensein des Kabinentürsignals . - Direct control of a shaft door locking device, in particular a Schschtürantrieb of the shaft door locking device by the shaft door control unit for unlocking / opening / closing the shaft door in the presence of the car door signal.
Der Erfindung liegt die Erkenntnis zugrunde, dass bei einer Anordnung einer solchen Schachttürverriegelvorrichtung an der Schachttür ohne mechanische Kopplung sichergestellt sein muss, dass die Schachttür im Normalbetrieb ausschliesslich dann öffenbar ist, wenn die Kabinentür an dieser Schachttür angeordnet ist. Normalbetrieb bedeutet in diesem Zusammenhang, dass die Aufzugskabine in einem Betriebszustand ist, der ein Transportieren von Passagieren oder Gütern zwischen verschiedenen Stockwerken ermöglicht. The invention is based on the finding that when such a shaft door locking device is arranged on the shaft door without mechanical coupling, it must be ensured that the shaft door can only be opened during normal operation when the car door is arranged on this shaft door. normal operation in this context means that the elevator car is in an operating state that allows passengers or goods to be transported between different floors.
Der Schachttürsensor ist derart an der Schachttür angeordnet, dass das durch den Kabinentürsignalgeber generierte Kabinentürsignal durch den Schachttürsensor empfangbar ist, wobei der Schachttürsensor im Aufzugsschacht ebenso an einer der den Aufzugsschacht seitlich begrenzenden Aufzugswände fixierbar/fixiert bzw. anordenbar/angeordnet sein kann. Insbesondere kann der Schachttürsensor unmittelbar an der Schachttür oder an der den Aufzugsschacht begrenzenden Aufzugswand anordenbar/angeordnet bzw. fixierbar/fixiert sein, an welcher Aufzugswand die Schachttür angeordnet ist. The shaft door sensor is arranged on the shaft door in such a way that the car door signal generated by the car door signal transmitter can be received by the shaft door sensor, with the shaft door sensor in the elevator shaft also being fixable/fixable or locatable/arranged on one of the elevator walls laterally delimiting the elevator shaft. In particular, the shaft door sensor can be arranged/arranged or fixed/fixed directly on the shaft door or on the elevator wall delimiting the elevator shaft, on which elevator wall the shaft door is arranged.
Durch den an der Kabinentür angeordneten Kabinentürsignalgeber ist ein Kabinentürsignal generierbar. Dieses Kabinentürsignal ist vom Schachttürsensor empfangbar, wenn die Aufzugskabine an der Schachttür angeordnet ist. Das Kabinentürsignal wird an die Schachttürsteuereinheit übermittelt bzw. ist an die Schachttürsteuereinheit übermittelbar. Die erfolgte Übermittlung der Information, dass das Kabinentürsignal vom Schachttürsensor empfangen ist, ist demnach eine Voraussetzung für die Entriegelung und/oder Öffnung der Schachttür, so dass eine Entriegelung und/oder Öffnung durch die Schachtürverriegelvorrichtung unmittelbar umsetzbar ist. Entsprechend ist die Sicherheit von auf dem Stockwerk befindlichen Personen sichergestellt, wenn die Schachttür - bei derart gesicherter Anwesenheit der Aufzugskabine - geöffnet wird. A car door signal can be generated by the car door signal transmitter arranged on the car door. This car door signal can be received by the shaft door sensor when the elevator car is arranged at the shaft door. The car door signal is transmitted to the shaft door control unit or can be transmitted to the shaft door control unit. The successful transmission of the information that the car door signal has been received by the shaft door sensor is therefore a prerequisite for unlocking and/or opening the shaft door, so that unlocking and/or opening by the shaft door locking device can be implemented directly. Accordingly, the safety of people on the floor is ensured when the shaft door is opened—with the presence of the elevator car secured in this way.
Schachttürverriegelvorrichtung wie vorangehend und im Folgenden beschrieben kann aus einer Schachttürverriegelung und/oder einem aktiven Schachttürantrieb bestehen. Shaft door locking device as described above and below can consist of a shaft door locking device and/or an active shaft door drive.
In einer Ausführungsform besteht die Schachttürverriegelvorrichtung nur aus einer Schachttürverrigelung, wobei die Schachttür durch die Schachtverriegelung in einem geschlossenen Zustand blockiert werden kann. Vorteilhaft ist die Schachttür so ausgebildet, dass die Schachttürverriegelung die Schachttür in einem geschlossenen Zustand auf eine fail-safe Art blockieren kann. Das heisst, dass die Schachttürverriegelung, so ausgebildet ist, dass sie selbst bei Ausfall der Energieversorgung die geschlossen Schachttür blockiert. Dies kann bspw. mit einem durch die Gravitation nach unten bewegten Bolzen umgesetzt sein. Dieser Bolzen kann aktiv, bspw. durch Bestromung eines Elektromagneten gegen die Gravitation in einem zweiten nicht blockierenden Zustand gehalten werden. Weiter kann der Bolzen und die Tür so ausgeführt sein, dass der Bolzen in einem nicht geschlossenen Zustand der Tür vom Türblatt am Einnehmen des blockierenden Zustands gehindert wird. Der Bolzen kann also nur bei geschlossener Schachttür den Zustand, in welchem er die Schachttür verriegelt einnehmen. Werden die zwei beschriebenen Zustände (blockierend/nicht blockierend) durch einen Sensor überwacht und stellt der Sensor den blockierenden Zustand fest, so kann mit Sicherheit auf eine geschlossene Schachttür geschlossen werden und die Aufzugskabine kann bewegt werden. In allen anderen Zuständen (nicht blockiert oder kein Signal (Ausfall des Sensors)) wird das Bewegen der Aufzugskabine blockiert.In one embodiment, the shaft door locking device consists only of a shaft door lock, it being possible for the shaft door to be blocked in a closed state by the shaft lock. The shaft door is advantageously designed in such a way that the shaft door lock can block the shaft door in a fail-safe manner when it is in a closed state. This means that the landing door lock is designed in such a way that even if the Power supply blocked the closed shaft door. This can be implemented, for example, with a bolt that is moved downwards by gravity. This bolt can be actively held in a second, non-blocking state against gravity, for example by energizing an electromagnet. Furthermore, the bolt and the door can be designed in such a way that the bolt is prevented from assuming the blocking state by the door leaf when the door is not in a closed state. The bolt can therefore only assume the state in which it locks the shaft door when the shaft door is closed. If the two states described (blocking/non-blocking) are monitored by a sensor and the sensor detects the blocking state, it can be concluded with certainty that the shaft door is closed and the elevator car can be moved. In all other states (not blocked or no signal (sensor failure)), the movement of the elevator car is blocked.
In dieser Ausführungsform ist die Schachttürverrieglung, das heisst bspw. der Elektromagneten und der Sensor durch eine unmittelbare Ansteuerung der Schachttürsteuereinheit bei Empfang eines Kabinentürsignale s des Kabinentürsignalgebers durch den Schachttürsensor entriegelbar. Vorteilhaft ist, dass die Schachttür ausschliesslich entriegelbar ist, wenn die Aufzugskabine an der Schachttür angeordnet ist. Demzufolge ist eine Öffnung der Schachttür nicht ermöglicht, wenn die Aufzugskabine nicht an der Schachttür angeordnet ist. Folglich ist die Sicherheit von auf dem Stockwerk befindlichen Personen gewährleistet, insbesondere dann, wenn versucht wird, den mindestens einen Türflügel der Schachttür manuell, d. h. von Hand, aus seiner geschlossenen Position in Richtung seiner Offenposition zu verschieben. In this embodiment, the landing door lock, ie for example the electromagnet and the sensor, can be unlocked by direct activation of the landing door control unit when a car door signal s from the car door signal transmitter is received by the landing door sensor. It is advantageous that the shaft door can only be unlocked when the elevator car is arranged on the shaft door. Consequently, the shaft door cannot be opened if the elevator car is not arranged on the shaft door. Consequently, the safety of people on the floor is guaranteed, especially when trying to open the at least one door leaf of the landing door manually, d. H. by hand to move from its closed position towards its open position.
In einer weiteren Ausführungsform besteht die Schachttürverriegelvorrichtung nur aus einem Schachttürantrieb. In dieser Ausführungsform umfasst also jede der Schachttüren einen eignen Schachttürantrieb. Der Schachttürantrieb blockiert die Öffnung der Schachtür und führt in einem zweiten Zustand die Öffnung bzw. Schliessung der Schachttür aktiv herbei. Der Schachttürantrieb agiert so als eine Schachttürverriegelvorrichtung. Der Schachttürantrieb ist durch eine unmittelbare Ansteuerung der Schachttürsteuereinheit bei Empfang eines Kabinentürsignale s des Kabinentürsignalgebers durch den Schachttürsensor entriegelbar, das heisst aus dem blockierenden in den bewegenden Zustand schaltbar. Vorteilhaft ist hier, dass die Schachttür ausschliesslich entriegelbar ist, wenn die Aufzugskabine an der Schachttür angeordnet ist. Demzufolge ist eine Öffnung der Schachttür nicht ermöglicht, wenn die Aufzugskabine nicht an der Schachttür angeordnet ist. Folglich ist die Sicherheit von auf dem Stockwerk befindlichen Personen gewährleistet, insbesondere dann, wenn versucht wird, den mindestens einen Türflügel der Schachttür manuell, d. h. von Hand, aus seiner geschlossenen Position in Richtung seiner Offenposition zu verschieben. In a further embodiment, the shaft door locking device consists only of a shaft door drive. In this embodiment, therefore, each of the shaft doors has its own shaft door drive. The shaft door drive blocks the opening of the shaft door and, in a second state, actively brings about the opening or closing of the shaft door. The landing door operator thus acts as a landing door locking device. The shaft door drive can be unlocked by direct activation of the shaft door control unit when a car door signal s from the car door signal transmitter is received by the shaft door sensor, ie it can be switched from the blocking to the moving state. It is advantageous here that the shaft door can only be unlocked when the elevator car is arranged on the shaft door. Consequently, an opening of the shaft door is not possible when the Elevator car is not arranged on the shaft door. Consequently, the safety of people on the floor is guaranteed, in particular when an attempt is made to move the at least one door leaf of the landing door manually, ie by hand, from its closed position towards its open position.
In einer weiteren Ausführungsform besteht die Schachttürverriegelvorrichtung aus einer Kombination der beiden vorangehend genannten Ausführungsformen mit Bolzen und Schachttürantrieb . In a further embodiment, the shaft door locking device consists of a combination of the two previously mentioned embodiments with a bolt and a shaft door drive.
Bei einer Ausführungsform der Aufzugsanlage sind der Schachttürsensor derart an der Schachttür und der Kabinentürsignalgeber derart an der Kabinentür angeordnet, dass das Kabinentürsignal durch den Schachttürsensor empfangbar ist, wenn die Kabinentür in einer Türöffnungszone der Schachttür angeordnet ist. In one embodiment of the elevator system, the shaft door sensor is arranged on the shaft door and the car door signal transmitter is arranged on the car door in such a way that the car door signal can be received by the shaft door sensor when the car door is arranged in a door opening zone of the shaft door.
Die Aufzugskabine bzw. die Kabinentür ist dann an einer solchen Türöffhungszone angeordnet, wenn die Aufzugskabine vom Stockwerk bei geöffneter Schacht- und Kabinentür derart betretbar ist, dass ein Abstürzen in den Aufzugsschacht vom Stockwerk heraus gemäss geltender Sicherheitsbestimmungen verunmöglicht ist. Demnach ist ein Niveauunterschied zwischen dem Fussboden der Aufzugskabine und der Bodenfläche des Stockwerks bis zu einem gewissen Mass ermöglicht. Im Falle beispielhaft eines Stromausfalls und einer in diesem Zusammenhang im Aufzugsschacht festgesetzten Aufzugskabine können Personen aus der Aufzugskabine durch die geöffnete Schacht- und Kabinentür evakuiert werden, selbst wenn die Bodenfläche der Aufzugskabine nicht plan zur Bodenfläche des Stockwerks ausgerichtet ist. The elevator car or the car door is arranged in such a door opening zone when the elevator car can be entered from the floor with the shaft and car door open in such a way that falling into the elevator shaft from the floor is impossible according to applicable safety regulations. Accordingly, a level difference between the floor of the elevator car and the floor surface of the floor is allowed to a certain extent. For example, in the event of a power failure and an elevator car stuck in the elevator shaft in this context, people can be evacuated from the elevator car through the open shaft and car door, even if the floor surface of the elevator car is not level with the floor surface of the floor.
Bei einer Ausführungsform der Aufzugsanlage ist der Kabinentürsignalgeber als Magnet, insbesondere als Permanentmagnet, ausgebildet. Vorteilhaft ist, dass ein mittels des Kabinentürsignalgebers generiertes Kabinentürsignal unabhängig von vorherrschenden Bedingungen im Aufzugschacht durch den Schachttürsensor empfangbar ist. Beispielhaft ist ein solcher Magnet im Wesentlichen gegenüber extremerWärme beziehungsweise Kälte, Verschmutzung oder hoher Luftfeuchte unempfindlich. In dieser Auführungsform ist der Schachttürsensor als Magnetfelddetektor ausgeführt, so dass dieser Anordnung der Aufzugskabine in der Nähe der Schachttür Eine Ausführungsform der Aufzugsanlage umfasst einen Kabinentürantrieb zur Schliessung/Öffnung/Entriegelung der Kabinentür und einen Kabinentürsensor, welcher Kabinentürsensor an der Kabinentür angeordnet ist, und einen Schachttürsignalgeber, welcher Schachttürsignalgeber an der Schachttür angeordnet ist, und eine mit dem Kabinentürsensor wirkverbundene Kabinentürsteuereinheit, durch welche Kabinentürsteuereinheit der Kabinentürantrieb zur Schliessung/Öffnung der Kabinentür bei Empfang eines Schachttürsignales des Schachttürsignalgebers durch den Kabinentürsensor unmittelbar ansteuerbar ist. In one embodiment of the elevator system, the car door signal generator is designed as a magnet, in particular as a permanent magnet. It is advantageous that a car door signal generated by means of the car door signal generator can be received by the shaft door sensor independently of the prevailing conditions in the elevator shaft. For example, such a magnet is essentially insensitive to extreme heat or cold, dirt or high humidity. In this embodiment, the shaft door sensor is designed as a magnetic field detector, so that the elevator car is arranged in the vicinity of the shaft door One embodiment of the elevator system includes a car door drive for closing/opening/unlocking the car door and a car door sensor, which car door sensor is arranged on the car door, and a shaft door signal generator, which shaft door signal generator is arranged on the shaft door, and a car door control unit that is operatively connected to the car door sensor, through which car door control unit the car door drive for closing/opening the car door can be controlled directly by the car door sensor upon receipt of a shaft door signal from the shaft door signal transmitter.
Eine Ausführungsform des Verfahrens umfasst die folgenden Verfahrensschritte: One embodiment of the method comprises the following method steps:
- Generieren eines Schachttürsignals mittels eines an der Schachttür angeordneten Schachttürsignalgebers, - Generating a shaft door signal by means of a shaft door signal generator arranged on the shaft door,
- Empfangen des Schachttürsignals mittels eines an der Kabinentür angeordneten Kabinentürsensors, - receiving the shaft door signal by means of a car door sensor arranged on the car door,
- Übermitteln des Schachttürsignals an eine Kabinentürsteuereinheit zum Öffnen/Schliessen der Kabinentür bei Vorhandensein des Schachttürsignales. - Transmission of the shaft door signal to a car door control unit for opening/closing the car door in the presence of the shaft door signal.
Der Kabinentürsensor ist somit an der Kabinentür angeordnet bzw. fixiert oder kann in der Umgebung der Kabinentür an der Aufzugskabine angeordnet/fixiert sein, so dass das durch den Schachttürsignalgeber generierte Schachttürsignal durch den Kabinentürsensor empfangbar ist. The car door sensor is thus arranged or fixed on the car door or can be arranged/fixed in the vicinity of the car door on the elevator car, so that the shaft door signal generated by the shaft door signal generator can be received by the car door sensor.
Derart ist ermöglicht, dass einerseits erkennbar ist, dass die Aufzugskabine mittels Kabinentürsignal an der Schachttür angeordnet ist und andererseits erkennbar ist, dass die Schachttür an der Aufzugskabine angeordnet ist. Demnach ist erkennbar, dass mittels einer solchen Anordnung eine erhöhte Sicherheit realisierbar ist, da jeder der Sensoren bzw. Signalgeber einer bestimmten Fehler- bzw. Ausfallwahrscheinlichkeit unterliegen. Demnach ist bei einer gegebenen Ausfallwahrscheinlichkeit des Kabinentür- oder des Schachttürsensors ermittelbar, ob die Aufzugskabine tatsächlich an der Schachttür angeordnet ist, die durch den Kabinentürsensor detektiert ist. In anderen Worten ist damit ausgedrückt, dass eine erhöhte Sicherheit gegeben ist, wenn sowohl das Kabinentürsignal durch den Schachttürsensor als auch das Schachttürsignal durch den Kabinentürsensor gleichzeitig empfangbar ist bzw. empfangen wird. Darüber hinaus kann das Schachttürsignal eine Identifikationsmerkmai beinhalten, um die Sicherheit weiter zu erhöhen. This makes it possible, on the one hand, to recognize that the elevator car is arranged on the shaft door by means of a car door signal and, on the other hand, to recognize that the shaft door is arranged on the elevator car. Accordingly, it can be seen that increased security can be achieved by means of such an arrangement, since each of the sensors or signal generators is subject to a certain probability of error or failure. Accordingly, with a given probability of failure of the car door sensor or the shaft door sensor, it can be determined whether the elevator car is actually arranged at the shaft door that is detected by the car door sensor. In other words, this means that there is increased safety if both the car door signal can be received or is received by the car door sensor at the same time by the shaft door sensor. In addition, the landing door signal can contain an identification feature to further increase security raise.
Eine Ausführungsform des Verfahrens umfasst die folgenden Verfahrensschritte: One embodiment of the method comprises the following method steps:
- Übermitteln des Schachttürsignales vom Kabinentürsensor an die Schachttürsteuereinheit, - Transmission of the landing door signal from the cabin door sensor to the landing door control unit,
- unmittelbares Ansteuem des Schachttürverriegelvorrichtung durch die Schachttürsteuereinheit zum Öffhen/Schliessen der Schachttür bei Vorhandensein des Kabinentürsignals und des Schachttürsignals. - Direct activation of the shaft door locking device by the shaft door control unit for opening/closing the shaft door when the car door signal and the shaft door signal are present.
Demnach ist die Schachttür lediglich dann mittels des Schachttürverriegelvorrichtung entriegel-/öffen-/schliessbar, wenn der Kabinentürsensor das durch den Schachttürsignalgeber generierte Schachttürsignal zusätzlich des Kabinentürsignals empfangt. Vorzugsweise weist das Schachttürsignal das genannte Identifikationsmerkmai auf, so dass die Schachttürverriegelvorrichtung ausschliesslich dann eine Entriegelung/Öffhung/Schliessung der Schachttür ausführen kann, wenn das Schachttürsignal derselben Schachttür durch den Kabinentürsensor empfangen wird. Accordingly, the shaft door can only be unlocked/opened/closed by means of the shaft door locking device when the car door sensor receives the shaft door signal generated by the shaft door signal transmitter in addition to the car door signal. The shaft door signal preferably has the said identification feature, so that the shaft door locking device can only unlock/open/close the shaft door when the shaft door signal of the same shaft door is received by the car door sensor.
Bei einer Ausführungsform der Aufzugsanlage ist die Kabinentürsteuereinheit mit der Schachttürsteuereinheit wirkverbunden und der Schachttürverriegelvorrichtung durch die Schachttürsteuereinheit zur Entriegelung/Schliessung/Öffhung der Schachttür unmittelbar ansteuerbar ist bei Empfang eines durch den Schachttürsignalgeber am Kabinentürsensor ausgelösten Schachttürsignales. Mittels einer solchen Wirkverbindung kann abgeglichen werden, dass die Kabinentür an der zur öffnenden Schachttür angeordnet ist. Demnach ist die Schachttür lediglich öffenbar, wenn sowohl das Schachttürsignal als auch das Kabinentürsignal daraufhindeuten, dass die Kabinentür an der Schachttür angeordnet ist. Entsprechend ist die Sicherheit erhöht, da eines der Kabinentürsignale und des Schachttürsignals fehlerhaft sein können. In one embodiment of the elevator system, the car door control unit is operatively connected to the shaft door control unit and the shaft door locking device can be controlled directly by the shaft door control unit to unlock/close/open the shaft door upon receipt of a shaft door signal triggered by the shaft door signal generator on the car door sensor. By means of such an operative connection, it can be adjusted that the car door is arranged on the shaft door to be opened. Accordingly, the shaft door can only be opened if both the shaft door signal and the car door signal indicate that the car door is arranged on the shaft door. Accordingly, safety is increased because one of the car door signals and the shaft door signal may be faulty.
Bei einer Ausführungsform der Aufzugsanlage sind die Schachttürsteuereinheit und die Kabinentürsteuereinheit drahtlos miteinander verbunden oder verbindbar. Die Kabinentürsteuereinheit kann unmittelbar an der Kabinentür und somit an der Aufzugskabine angeordnet sein und die Schachttürsteuereinheit unmittelbar an der Schachttür. Folglich kann eine zusätzliche Sicherheit erzeugt werden. Eine Ausführungsform der Aufzugsanlage umfasst eine Kabinensteuereinheit, ein Absolutpositionssystem, mittels welchen Absolutpositionssystems ein Positionssignal an die Schachttürsteuereinheit übermittelbar ist, und/oder ein Bremssystem zur Festsetzung der Aufzugskabine im Aufzugsschacht, mittels welchen Bremssystems ein Feststellsignal an die Kabinensteuereinheit übermittelbar ist. Zur weiteren Erhöhung der Sicherheit sind das Positionssignal und/oder das Feststellsignal derart auswertbar, dass feststellbar ist, dass bzw. wo die Aufzugskabine innerhalb des Aufzugsschachtes festgesetzt ist. Das heisst bei an der Schachttür anwesender Kabinentür, insbesondere ein durch den Schachttürsensor detektiertes Kabinentürsignal und ggf. darüber hinaus ein durch den Kabinentürsensor detektiertes Schachttürsignal, zusätzlich mittels des Positionssignals bzw. des Feststellsignals gesichert die Position der Aufzugskabine feststellbar ist. In one embodiment of the elevator system, the shaft door control unit and the car door control unit are or can be connected to one another wirelessly. The car door control unit can be arranged directly on the car door and thus on the elevator car, and the shaft door control unit directly on the shaft door. As a result, additional security can be created. One embodiment of the elevator system includes a car control unit, an absolute position system, by means of which absolute position system a position signal can be transmitted to the shaft door control unit, and/or a braking system for fixing the elevator car in the elevator shaft, by means of which braking system a locking signal can be transmitted to the car control unit. To further increase safety, the position signal and/or the locking signal can be evaluated in such a way that it can be determined that or where the elevator car is fixed within the elevator shaft. This means that when the car door is present at the shaft door, in particular a car door signal detected by the shaft door sensor and possibly also a shaft door signal detected by the car door sensor, the position of the elevator car can also be determined using the position signal or the locking signal.
Im Folgenden wird die Erfindung anhand von Figuren näher erläutert. Es zeigen: The invention is explained in more detail below with reference to figures. Show it:
Figur 1 : eine Aufzugsanlage mit einer in der Aufzugsanlage verfahrbaren Aufzugskabine; und FIG. 1: an elevator system with an elevator car that can be moved in the elevator system; and
Figur 2: eine schematische Darstellung der in Figur 1 gezeigten Aufzugsanlage. FIG. 2: a schematic representation of the elevator system shown in FIG.
Figur 1 zeigt eine üblicherweise innerhalb von Gebäuden angeordnete Aufzugsanlage 1. Die Aufzugsanlage 1 umfasst eine in einem üblicherweise vertikal ausgerichteten Aufzugsschacht 3 verfahrbare Aufzugskabine 5. An der Aufzugskabine 5 ist eine Kabinentür 7 angeordnet. Der Aufzugsschacht 3 weist mehrere übereinander angeordnete Türöffnungen 9 auf, um den Zugang zu einzelnen Stockwerken des Gebäudes zu ermöglichen. An einer jeden dieser Türöffnungen 9 ist eine Schachttür 11 angeordnet. Ist die Aufzugskabine 5 bzw. die an der Aufzugskabine 5 angeordnete Kabinentür 7 an einer dieser Schachttüren 11 angeordnet, ist die Aufzugskabine 5 bei geöffneter Kabinentür 7 und geöffneter Schachttür 11 vom der Schachttür 11 zugeordneten Stockwerk aus begehbar. FIG. 1 shows an elevator installation 1 usually arranged inside buildings. The elevator installation 1 comprises an elevator car 5 which can be moved in an elevator shaft 3 which is usually aligned vertically. A car door 7 is arranged on the elevator car 5 . The elevator shaft 3 has a plurality of door openings 9 arranged one above the other in order to enable access to individual floors of the building. A shaft door 11 is arranged at each of these door openings 9 . If the elevator car 5 or the car door 7 arranged on the elevator car 5 is arranged on one of these shaft doors 11 , the elevator car 5 can be accessed from the floor assigned to the shaft door 11 when the car door 7 and the shaft door 11 are open.
Die Kabinentür 7 weist einen Kabinentürantrieb 35 und ein Kabinentürsignalgeber 17 auf. Eine jede der Schachttüren 11 weist jeweils einen Schachttürantrieb 13 auf. Einem jeden dieser Schachttürantriebe 13 ist eine Schachttürsteuereinheit 19 zugeordnet, durch welche Schachttürsteuereinheit 19 der ihr zugeordnete Schachttürantrieb 13 unmittelbar ansteuerbar ist. Mittels der Ansteuerung des Schachttürantriebes 13 ist die dem Schachttürantrieb 13 zugeordnete Schachttür 11 entriegel- bzw. offen- und schliessbar. An jeder der Schachttüren 11 ist jeweils ein Schachttürsensor 15 derart angeordnet, dass das vom Kabinentürsignalgeber 17 generierte Kabinentürsignal durch den Schachttürsensor 15 bei entsprechender Stellung der Aufzugskabine 5 empfangbar ist. Entsprechend ist der Schachttürsensor 15 einer jeder der Schachttüren 11 mit der Schachttürsteuereinheit 19 derselben Schachttür 11 wirkverbunden. The car door 7 has a car door drive 35 and a car door signal generator 17 . Each of the shaft doors 11 has a shaft door drive 13 in each case. Each of these shaft door drives 13 is assigned a shaft door control unit 19, by means of which shaft door control unit 19 the shaft door drive 13 assigned to it can be controlled directly. The shaft door 11 assigned to the shaft door drive 13 can be unlocked or opened and closed by means of the activation of the shaft door drive 13 . A shaft door sensor 15 is arranged on each of the shaft doors 11 in such a way that the car door signal generated by the car door signal generator 17 can be received by the shaft door sensor 15 when the elevator car 5 is in a corresponding position. Correspondingly, the shaft door sensor 15 of each of the shaft doors 11 is operatively connected to the shaft door control unit 19 of the same shaft door 11 .
Der vorzugsweise als Magnet, insbesondere als Permanentmagnet, ausgebildete Kabinentürsignalgeber 17 bewirkt eine Generierung eines Kabinentürsignals, welches folglich durch den Schachttürsensor 15 empfangbar ist, wenn die Aufzugskabine 5 an der dem Schachttürsensor 15 zugeordneten Schachttür 11 angeordnet ist. Der Schachttürsensor 15 ist mit der Schachttürsteuereinheit 19 wirkverbunden, so dass das Kabinentürsignal an die Schachttürsteuereinheit 19 übertragbar ist bzw. übertragen wird. The car door signal generator 17, which is preferably designed as a magnet, in particular as a permanent magnet, causes a car door signal to be generated, which can consequently be received by the shaft door sensor 15 when the elevator car 5 is arranged on the shaft door 11 assigned to the shaft door sensor 15. The shaft door sensor 15 is operatively connected to the shaft door control unit 19 so that the car door signal can be or is transmitted to the shaft door control unit 19 .
Weiter umfasst die Aufzugsanlage 1 eine, vorzugsweise an der Aufzugskabine 5 fixierte, Kabinentürsteuereinheit 31 auf und kann einen Kabinentürsensor 29 umfassen, der an der Aufzugskabine 5 bzw. an der Kabinentür 7 angeordnet ist. Durch den Kabinentürsensor 29 ist ein durch einen Schachttürsignalgeber 33 generiertes Schachttürsignal empfangbar. An einer jeden Schachttür 11 ist jeweils ein solcher dieser Schachttür 11 zugeordneter Schachttürsignalgeber 33 anordenbar. Weiter weist die Aufzugskabine 5 ein Absolutpositionssystem 37, welches bspw. als Laserpositionssystem ausgebildet ist, und ein Bremssystem 39 auf. The elevator installation 1 also includes a car door control unit 31 , preferably fixed to the elevator car 5 , and can include a car door sensor 29 , which is arranged on the elevator car 5 or on the car door 7 . A shaft door signal generated by a shaft door signal generator 33 can be received by the car door sensor 29 . One such shaft door signal transmitter 33 assigned to this shaft door 11 can be arranged on each shaft door 11 . The elevator car 5 also has an absolute positioning system 37 which is designed, for example, as a laser positioning system, and a braking system 39 .
Figur 2 zeigt eine schematische Darstellung der in Figur 1 gezeigten Aufzugsanlage 1. In der schematischen Darstellung sind die Schachttürsteuereinheit 19 und die Kabinentürsteuereinheit 31 dargestellt. Die Schachttürsteuereinheit 19 und die Kabinentürsteuereinheit 31 sind, vorzugsweise drahtlos, miteinander wirkverbunden. Darüber hinaus ist das Absolutpositionssystem 37 und das Bremssystem 39 zur Festsetzung der Aufzugskabine 5 dargestellt. Das Absolutpositionssystem 37 erzeugt zu jeder Zeit oder periodisch wiederkehrend ein Positionssignal. Das Positionssignal umfasst die Information, an welcher Stelle die Aufzugskabine 5 im Aufzugsschacht 3 angeordnet ist. Das eine Feststellbremse umfassende Bremssystem 39 erzeugt im Falle einer Festsetzung der Aufzugskabine 5 im Aufzugsschacht 3 ein Feststellsignal. Demnach wird das Feststellsignal generiert, wenn die Feststellbremse blockiert und folglich die Aufzugskabine 5 im Aufzugsschacht 3 nicht mehr im Aufzugsschacht verfahrbar ist. FIG. 2 shows a schematic representation of the elevator installation 1 shown in FIG. 1. The shaft door control unit 19 and the car door control unit 31 are represented in the schematic representation. The shaft door control unit 19 and the car door control unit 31 are operatively connected to one another, preferably wirelessly. In addition, the absolute position system 37 and the braking system 39 for fixing the elevator car 5 are shown. The absolute position system 37 generates a position signal at any time or periodically. The position signal includes the information at which point the elevator car 5 is arranged in the elevator shaft 3 . The brake system 39 comprising a parking brake generates a parking signal in the event that the elevator car 5 is stuck in the elevator shaft 3 . Accordingly, the parking signal is generated when the parking brake blocks and consequently the Elevator car 5 in the elevator shaft 3 can no longer be moved in the elevator shaft.
Das Positionssignal ist an die Schachttürsteuereinheit 19 übertragbar. Das Feststellsignal ist an die Kabinentürsteuereinheit 31 übertragbar. Durch die Schachttürsteuereinheit 19 sind das Kabinentürsignal, das Positionssignal und das Feststellsignal empfangbar und auswertbar. Ergibt die Auswertung, dass die Aufzugskabine 5 an der der Schachttürsteuereinheit 19 zugeordneten Schachttür 11 sowohl angeordnet als auch festgesetzt ist, ist der der Schachttürsteuereinheit 19 zugeordnete Schachttürantrieb 13 unmittelbar zur Öffnung der Schachttür 11 ansteuerbar. The position signal can be transmitted to the shaft door control unit 19 . The detection signal can be transmitted to the car door control unit 31 . The car door signal, the position signal and the locking signal can be received and evaluated by the shaft door control unit 19 . If the evaluation shows that the elevator car 5 is both arranged and fixed on the shaft door 11 assigned to the shaft door control unit 19 , the shaft door drive 13 assigned to the shaft door control unit 19 can be activated directly to open the shaft door 11 .
Zusätzlich kann das Schachttürsignal von der Kabinentürsteuereinheit 31 an die Schachttürsteuereinheit 19 für eine weitergehende Auswertung übertragbar sein. Ergibt die Auswertung, dass das Schachttürsignal der Schachttür 11 des anzusteuemden Schachttürantriebes 13 zuordenbar ist, ist mittels einer solchen Auswertung eine höhere Sicherheit erreichbar. In addition, the shaft door signal can be transmitted from the car door control unit 31 to the shaft door control unit 19 for further evaluation. If the evaluation shows that the shaft door signal can be assigned to the shaft door 11 of the shaft door drive 13 to be actuated, greater safety can be achieved by means of such an evaluation.
