Definitions

  • the invention relates to a method for monitoring shaft doors of a lift installation as defined in the patent claims.
  • Elevator systems usually have shaft doors, which in the closed state separate the elevator shaft from the adjoining rooms on each floor.
  • the load-receiving means (elevator car) is equipped with a door, which is referred to as a car door and moves together with the elevator car from floor to floor.
  • the opening and closing of the doors is normally effected during a floor stop of the elevator car by a car door drive controlled by an elevator control.
  • the cabin door wings are coupled to the respective corresponding shaft door wings, so that the shaft door leaves join in the movement of the cabin door wings.
  • a shaft door may only be open when the elevator car stops on the assigned floor.
  • each shaft door latch is associated with a safety contact, which forms part of an electrical safety circuit and interrupts this when not correctly locking the shaft door leaf.
  • safety circuits which in the case of tall buildings a Series connection of more than twenty safety contacts are known as one of the main causes of disturbances of the elevator operation.
  • the contact resistance of the individual safety contacts increases in a relatively short time, which causes such a high voltage drop in series connection of many contacts that the safety circuit system shuts off the elevator even with correctly closed doors.
  • US 5,644,111 discloses a hoistway door monitoring system for a conventional elevator system, which is intended to counteract the problems described above.
  • a non-contact sensor in the form of a photoelectric detector with transmitter and receiver is installed on each floor on the shaft wall opposite the hoistway door. Its light beam is directed towards the closed edge area of the closed shaft door leaf and is reflected by the shaft door wing, provided that the shaft door leaf is completely closed and the elevator car is not located between the sensor and the shaft door. If the landing door wing is not completely closed and the elevator car is not in the sensor area, then the light beam exits into the elevator lobby, from where it no longer has sufficient strength is reflected, so that the receiver of the photoelectric detector can register this state.
  • a corresponding information is forwarded to the elevator control, which stops the elevator and triggers suitable alarm signals (siren, flashes of light on floor, etc.). If the elevator car is located on the floor with the shaft door not closed, the light beam of the sensor is reflected by the rear cabin wall, so that the sensor rightly does not detect an impermissible state.
  • suitable alarm signals siren, flashes of light on floor, etc.
  • the present invention has for its object to provide a method for monitoring shaft doors of an elevator system, with which the disadvantages mentioned can be avoided, that is, in which in particular a safety circuit with a plurality of successively connected shaft door safety contacts is avoided, in which the The number of required monitoring sensors is reduced, and its effectiveness can not be influenced by persons or objects present in front of the shaft door or by the light conditions in the elevator lobby.
  • the invention is therefore based on the idea to solve the problems that are known in connection with the hitherto conventional plurality of sensors and / or contacts for monitoring shaft doors by a method in which at least during the detection phases by a transmitter of a shaft door monitoring sensor a multilevel beam is emitted in the form of collimated electromagnetic waves detected by a receiver and is affected by a not completely closed shaft door leaf and / or by a non-latching shaft door latch such that a receiver the shaft door monitoring sensor is detected that a shaft door is not complete closed and / or not locked, this information being signaled by the shaft door monitoring sensor to the elevator control.
  • Detection phases are those periods of time in which all shaft doors must be closed and locked when the program is executed.
  • the monitoring of the locking state of the shaft door latch is preferably carried out in that the beam is interrupted or reflected by the Schachtfriegeln associated aperture, which protrude into the beam path when the respective shaft door latch is not in its locked position.
  • the advantages achieved by the invention are essentially to be seen in that with a single shaft door monitoring sensor, the closed position and the locking state of a large number of shaft doors can be monitored without contact. This eliminates a major cause of breakdown while greatly reducing the cost of purchasing, installing, and subsequently maintaining a large number of monitoring sensors and / or monitoring contacts. Moreover, in this method, the beam of the shaft door monitoring sensor can not be influenced in any situation by persons or objects standing in front of the shaft door or by the light conditions in the elevator lobby.
  • an elevator car in motion is stopped by the elevator control, and / or it becomes optical and / or audible warnings on at least one of the floors when the hoistway door monitoring sensor signals a not completely closed hoistway door and / or an unlocked hoistway door latch during an operating condition in which all hoistway doors must be fully closed and locked. Stopping the elevator car prevents a person from being injured by the moving elevator car in the area of a shaft door which is unlocked as a result of a malfunction or due to unauthorized opening. With warning signals such as flashlight and / or siren to prevent passengers from approaching an unlocked or unlocked shaft door to ban the risk of falling into the elevator shaft.
  • a beam for sensing the closed position of the shaft door wing and the locking position of the shaft door latch is any type of electromagnetic waves, with which a sufficient length over the required length beam can be generated, which are connected by the shaft door wings and / or with the shaft door bolts mechanical components can be influenced so that a receiver can detect this influence.
  • electromagnetic waves that can be a danger to living things or destroy materials.
  • Laser light beams are thanks to the coherence, ie the in-phase of the electromagnetic beam forming the light beam Waves, even with large beam lengths very well bundled, ie the increase of the beam cross-sectional diameter with increasing beam length is very low.
  • beams which are formed by incoherent infrared light it is also possible to use beams which are formed by incoherent infrared light in order to save costs.
  • the monitoring length required to monitor all shaft doors can be divided into several sections, each section of at least one beam generated by a separate shaft door monitoring sensor with transmitter and receiver is monitored.
  • shaft door monitoring sensors are used which emit light beams in the wavelength ranges of ultraviolet light, visible light or infrared light.
  • Such sensors are commercially available and have the advantage that the beam path of the eye is visible or verifiable with simple sensors.
  • the beam is emitted by a transmitter, which is preferably arranged in the region of one shaft end (eg in the shaft head) and received and evaluated by a receiver, preferably in the region of the other Shaft end (eg in the pit) is located.
  • a transmitter which is preferably arranged in the region of one shaft end (eg in the shaft head) and received and evaluated by a receiver, preferably in the region of the other Shaft end (eg in the pit) is located.
  • transmitter / receiver principle arrangement has the shortest possible length of the beam path, which is the application of simpler and cheaper jet systems allows no elaborate alignment of a reflective surface and minimizes sensitivity to contamination.
  • the required monitoring length can also be achieved by sequential arrangement of several sections, each with a transmitter / receiver system.
  • the beam is emitted from a preferably mounted in the region of one end of the shaft transmitter toward a preferably in the region of the opposite shaft end mounted reflection surface, from where the beam to a receiver present in the region of the transmitter is detected, wherein the receiver is detected, whether the beam reaches the receiver or is interrupted as a result of a not fully closed shaft door panel or not in the locked position located Schachtfriegels.
  • reflection principle method transmitter and receiver integrated in a single device, which reduces the manufacturing cost of the shaft door monitoring sensor and greatly simplifies the installation in the bay.
  • the required monitoring length can be achieved by sequentially arranging a plurality of monitoring sections, each with a shaft door monitoring sensor according to the reflection principle.
  • the shaft door monitoring sensor is designed as a distance measuring device, for example in the form of a laser distance measuring device.
  • the beam is at least during the detection phases of a preferably mounted in the region of the shaft end transmitter in Direction emitted to a preferably in the region of the opposite shaft end main reflecting surface, so that the beam from this main reflection surface or from a reflection surface, which is formed by an associated with the associated shaft door or the shaft door latch mechanical component, and which protrudes into the beam in the case of a not completely closed shaft door panel and / or not in the locked position located Schachtfriegels, is reflected to a receiver present in the region of the transmitter.
  • the transmitter and the receiver of the beam are designed so that the distance traveled by the beam on its way from the transmitter over one of the reflection surfaces back to the receiver can be determined.
  • This embodiment of the method has the advantage that not only can it be ascertained that one of the shaft door leaves is not completely closed and / or one of the shaft door latches is not in the locked position, but that it is also possible to determine where, ie on which, basis of the measured distance Floor, the source of the disturbance is located.
  • the division of the required monitoring length into several sections is also possible with this method variant.
  • a particularly expedient embodiment of the invention is that the measured distance measured during the detection phase to a momentarily acting reflection surface and / or a determined therefrom identification of the floor and / or displayed. From the storage data or the display, a maintenance expert can immediately recognize on which floor he has to search for a not fully closed shaft door wing or not located in the locked position shaft door latch.
  • An advantageous for certain arrangements of the shaft doors development of the inventive method is that for the shaft doors monitoring multiple independent beams can be applied. For example, so that the shaft door leaf and the associated shaft door latch can be monitored independently, or it can be monitored independently of each other several mechanically coupled shaft door leaves and / or the shaft door latch multi-leaf shaft doors. On the one hand, this results in a safety-related desirable redundancy of the shaft door monitoring. On the other hand, it is possible to distinguish between non-closed shaft door wings and unlocked shaft door locks, which makes it possible to respond optimally to different fault messages. For example, upon detection of an unlocked shaft door bolt while the shaft door is still closed, instead of an immediate emergency braking, a drive of the elevator car to the next stop can be continued, whereby a trapping of passengers can be avoided.
  • An interesting extension of the inventive method with beam deflection is that the beam of a equipped for distance measurement shaft door monitoring, after he has passed through the shaft door monitoring areas is directed by a further beam deflecting device in the vertical direction to a mounted on the elevator car reflecting surface, from where the beam to Recipient of the Shaft door monitoring sensor is reflected.
  • continuous information about the position of the elevator car can be generated within its shaft path, which can serve, for example, in a comparison circuit to increase the safety against malfunctions of a main cabin position detection.
  • remote-controlled additional locks acting on the shaft doors can be activated, preferably by the elevator control, if the shaft door monitoring sensor signals a not completely closed shaft door leaf and / or a shaft door latch not in locking position during an operating condition in which all Shaft doors should be closed.
  • the security against a person's fall and in particular against the intrusion of an unauthorized person into the elevator shaft can be substantially increased.
  • the additional locks are activated before the unlocked shaft door is opened so far that a person can pass through.
  • Another embodiment of the method which is particularly interesting in terms of safety can be achieved in elevator systems which are equipped with a shaft door monitoring sensor with distance measurement.
  • visual and / or audible warning signals and / or remotely controllable, acting on the shaft door latches on exclusively that floor can be activated at the shaft door during an operating condition in which all shaft doors should be closed and locked, not completely closed shaft door leaf and / or not located in the locked position shaft door latch can be detected.
  • Such a system has the advantage that alarms are only perceived on the floor concerned, so that people on the other floors are not unnecessarily disturbed. Additional latches for the landing door wings also act only on the floor concerned, so that maintenance personnel may be able to gain access to the elevator shaft via a separate, not additionally locked shaft door in the case of elevator cars that may have been shut down between two floors.
  • FIG. 1 schematically an elevator 1 m an elevator shaft 2 and an elevator car 3 is shown.
  • the elevator car is equipped with a car door 4, which has two car door leaves 5, which are moved horizontally for opening and closing by a mounted on the elevator car 3 door drive unit 6.
  • the elevator shaft 2 comprises three shaft doors 7, each having two shaft door leaves 8.
  • the opening and closing of a hoistway door 7 takes place by horizontal movement of its hoistway door panels 8 when the elevator car is on the corresponding floor, wherein the driving force for this horizontal movement is transmitted from the car door panels 5 to the hoistway door panels 8 by means of a door actuation mechanism.
  • the shaft door panels 8 are locked to a fixed part of the shaft doors by means of a shaft door bolt (not shown here).

  • Transmitter 10.1 and receiver 10.2 together form a shaft door monitoring sensor 10. The arrangement described here is referred to below as the transmitter / receiver principle.
  • the shaft door monitoring sensor of the elevator control signals that one of the landing door wings 8 is not completely closed or one of the shaft door latches is not in the locking position.
  • Detection phases are those periods of time in which all shaft doors must be closed and locked when the program is executed.
  • the jet 10.3 extends in a vertical plane lying between the shaft doors 7 and the car door 4 defined by the gap between the shaft door sills 14 and the car door sill 15. Since the jet in this embodiment of the method extends in the vertical direction between the shaft doors and the car door, it is advantageous if the radiation emission occurs only during the detection phase, so that passengers are not irritated by the - possibly visible - beam.
  • the beam 10.3 is influenced by apertures 12 associated with each shaft door 7, which are thus in communication with the shaft door wings and the shaft door bolts, so that they interrupt the jet 10.3 when the shaft door 7 is not completely closed and / or when a shaft door latch is not in the locking position this in Fig. 2 is shown in detail.

  • FIG. 4 again shows a shaft door leaf 8, which is not completely closed (door gap 25), and its shaft door latch 22 is therefore - possibly for another reason - is not in its locked position. Since in this situation the locking hook 22.2 of the shaft door bolt 22 does not act on the handlebar lever 24 carrying the panel 17, the panel 17 remains in its basic position resulting from the handlebar lever arrangement without outside influence, in which it interrupts the beam path of the beam 10.3.

Such is achieved by the fact that the closed position of the shaft door 8 arranged one above the other in the elevator shaft and the locking state of the shaft door latch 22 assigned to the shaft door leaves 8 are monitored separately. Such monitoring can be realized, for example, by having each of them in Fig. 4 shown individual rays 10.3 by two parallel, in the direction of the plane of the drawing staggered rays 10.3 ( Fig. 7 ), one of which is the lower edge 8.1 or the upper edge 8.2 of the associated shaft door leaf 8 and the other arranged slightly laterally of the shaft door panel 8 aperture 17 (corresponding to the aperture 17 in Fig. 4 ) supervised.

For example, when a locking error occurs, the moving elevator car can continue to drive to the next floor, while an emergency stop is generated when an open shaft door is detected. For example, if two beams monitoring the interlocks and one beam monitoring the closed position of all left-hand landing door panels could signal correct states, while a non-closed status is reported for the right-hand landing door panels, it could be concluded that there is a detection error in the hoistway door reported as not closed must be present and that the journey can be continued to the destination floor.

  6. Procédé selon une des revendications de 1 à 4, caractérisé en ce que, au moins pendant les phases de détection, le rayon (10.3) est émis par un poste émetteur (10.1) en direction d'une surface réfléchissante (11) placée de sorte à ce qu'elle soit éloignée de celui-ci de plusieurs distances d'étages, la surface réfléchissante (11) étant alignée de telle sorte qu'un rayon arrivant (10.3) est reflété vers un récepteur (10.2) installé dans le secteur du poste émetteur (10.1), auquel cas il est détecté par le récepteur (10.2) si le rayon (10.3) émis atteint le récepteur (10.2) ou s'il est interrompu à la suite d'un battant de porte palière (8) pas entièrement fermé ou d'un verrou de porte palière (22) ne se trouvant pas dans la position de verrouillage
  7. Procédé selon une des revendications de 1 à 4, caractérisé en ce que,
    au moins pendant les phases de détection, le rayon (10.3) est émis par un poste émetteur (10.1) en direction d'une surface réfléchissante principale (13) placée de sorte à ce qu'elle soit éloignée de celui-ci de plusieurs distances d'étages, et que
    le rayon est reflété par cette surface réfléchissante principale (13) ou par une surface réfléchissante (8.1, 8.2, 17) vers un récepteur (10.2) disponible dans le secteur du poste émetteur (10.1), cette surface réfléchissante avançant dans le rayon dans le cas d'un battant de porte palière (8) pas intégralement fermé et/ou d'un verrou de porte palière (22) ne se trouvant pas dans la position de verrouillage, et que
    le capteur de surveillance de porte palière (10) avec poste émetteur (10.1) et récepteur (10.2) est formé de telle sorte que la distance parcourue par le rayon (10.3) sur sa trajectoire à partir du poste d'émetteur (10.1) à travers une des surfaces réfléchissante (13, 8.1, 8.2, 17) et retour vers le récepteur (10.2) peut être déterminée et peut être signalisée au système de manoeuvre d'ascenseur.
  8. Procédé selon la revendication 7, caractérisé en ce que dès que et aussi longtemps que la distance déterminée parcourue par le rayon (10.3) est plus courte que la trajectoire à partir du poste émetteur (10.1) vers la surface réfléchissante principale (13) et retour vers le récepteur (10.2), un battant de porte palière (8) n'étant pas intégralement fermé et/ou un verrou de porte palière (22) ne se trouvant pas dans la position de verrouillage et signalisé au système de manoeuvre d'ascenseur par le capteur de surveillance de porte palière (10) ou par un dispositif d'évaluation relié en aval, auquel cas, si une telle situation se produit lors d'un état de fonctionnement dans lequel toutes les portes palières (7) devrait être fermées et verrouillées, la distance vers la surface réfléchissante momentanément opérante et/ou une identification déterminée de l'étage y découlant, à partir duquel le rayon (10.3) est reflété, est mémorisée et/ou indiquée.
  9. Procédé selon la revendication 7 ou 8, caractérisé en ce que la distance parcourue par le rayon (10.3) reflété est déterminée en employant une des méthodes suivantes:
    - mesurage de la durée de transit des impulsions individuelles de l'onde électromagnétique formant le rayon (10.3) (Time of Flight Measurement)
    - mesurage du décalage - ayant lieu entre émission et réception - de la position de phase des ondes électromagnétiques émises de façon cohérente et formant le rayon (10.3) (Phase Shift Measurement).
  10. Procédé selon une des revendications précédentes, caractérisé en ce que l'on a recours à plusieurs rayons indépendants (10.3) pour la surveillance des portes palières (7),
    - auquel cas les battants de porte palière (8) et les verrous de porte palière (22) sont supervisés indépendamment les uns des autres, ou
    - auquel cas les battants de porte palière (8) et/ou les verrous de porte palière (22) de portes palières à plusieurs verrous sont supervisés indépendamment les uns des autres.
  11. Procédé selon une des revendications précédentes, caractérisé en ce qu'un rayon 10.3, émis par un poste émetteur 10.1, est dévié dans la cage d'ascenseur, sur sa trajectoire vers un récepteur 10.2, à l'aide d'au moins un dispositif déviateur de rayon (33) fixé dans la cage d'ascenseur (2) de telle sorte qu'une distance verticale correspondante à plusieurs hauteurs d'étage sera parcourue par le rayon (10.3) à plusieurs reprises au niveau de différentes positions de la section transversale horizontale de la cage, auquel cas le rayon peut être influencé par des battants de porte palière (8) pas intégralement fermés et/ou par des diaphragmes (12; 17) positionnés étant dépendants de l'état de verrouillage des verrous de portes palières 22, dont les secteurs saisis par le rayon sont placés au niveau des différentes positions mentionnées.
  12. Procédé selon une des revendications précédentes, caractérisé en ce que si pendant un état de fonctionnement dans lequel toutes les portes palières (7) devraient être fermées, un battant de porte palière (8) pas intégralement fermé est signalisé, des verrouillages supplémentaires susceptibles d'être commandés à distance et agissant sur les battants de porte palière (8) peuvent être activés.
  13. Procédé selon une des revendications précédentes, caractérisé en ce que dans des installations d'ascenseur équipées d'un capteur de surveillance de porte palière (10) avec reconnaissance de distance, des signaux avertisseurs optiques et/ou acoustiques et/ou des verrouillages supplémentaires susceptibles d'être commandés à distance, agissant sur les battants de porte palière peuvent être exclusivement activés à l'étage, où l'on détecte au niveau des portes palières (7), pendant un état de fonctionnement dans lequel toutes les portes palières devraient être fermées et verrouillées, un battant de porte palière (8) n'étant pas intégralement fermé et/ou un verrou de porte palière (22) ne se trouvant pas dans la position de verrouillage.
