Definitions

  • the present invention relates to elevator installations.
  • the invention relates to a method for controlling a closing operation of an elevator door and a correspondingly configured elevator door locking system.
  • elevator cars carry people or goods between different levels or levels within a building.
  • the elevator car typically has a car door that can be opened and closed.
  • a storey door is provided as a rule in the building on each floor adjacent to a hoistway. While the car door can move with the elevator car, the landing doors are fixed stationary in the building. If the elevator car stops at a floor, the car door as well as the landing door of this floor can be opened so that passengers can enter or leave the elevator car. Subsequently, the car door and the landing door must be closed again before the elevator car can then be moved to another floor.
  • the car door and the landing door are mechanically coupled or otherwise synchronized with each other so that they always open and close simultaneously with each other.
  • the cabin door and the landing doors are summarized below under the term elevator doors.
  • a method for controlling a closing operation of an elevator door comprises at least the following steps: it is monitored and recognized whether a person is within a predetermined range in the vicinity of the elevator door. Then the elevator door is closed. If it has been detected that a person is within the predetermined range, it is monitored when closing, with which closing force the elevator door is closed and the closing operation is interrupted when the closing force exceeds a predetermined first limit. However, if it has been detected that no person is within the predetermined range, it is not monitored when closing, with which closing force the elevator door is closed. Alternatively, in this case, it can be monitored when closing, with which closing force the elevator door is closed, and the closing operation is interrupted when the closing force exceeds a predetermined second limit, which is higher than the first limit value.
  • an elevator door locking system which comprises a closable elevator door, a closing force measuring device, a person recognition device and a controller for controlling a closing operation of the elevator door.
  • the closing force measuring device is configured to measure a closing force with which the elevator door is closed.
  • the person recognition apparatus is configured to recognize whether a person is within a predetermined area near the elevator door.
  • the elevator door locking system as a whole is configured to perform a method according to an embodiment of the above first aspect of the invention.
  • an elevator installation which has such an elevator door locking system.
  • the first limit value provided for this purpose can be, for example, 150 N or less and thus low enough that persons are not endangered even in the event of a collision with an elevator door.
  • the Temporary limit to be set to a higher value, for example, to a limit of at least 200 N or alternatively at least 300 N or even at least 500 N. Eventually, the clamping force limitation can be temporarily even completely suspended.
  • elevator doors can be closed with forces sufficient to exert forces on the elevator door, e.g. to be overcome by strong air currents.
  • the elevator doors can thus be more reliably closed, especially in high-rise buildings with a strong chimney effect, whereby availability of the elevator system can be improved or its operation can be made more reliable.
  • the closing force limit remains activated in all cases, typically with a closing force limit of 150 N. If the closing force during a closing operation exceeds this limit should actually exceed the closing process is interrupted immediately, ie either no longer attempts to close the elevator door or the direction of movement is even reversed, ie the elevator door open again. This is carried out regardless of whether the elevator door actually collides with a person or whether the movement of the elevator door is inhibited, for example by strong attacking air currents. The safety of the passengers is therefore not endangered, but at worst the elevator doors are not or at least not closed promptly due to the activated closing force limit, so there may be delays in the operation of the elevator system, as they must be accepted in conventional elevator systems with clamping force limitation.
  • the method may be configured such that, unless it has been unequivocally established that a person or that no person is within the predetermined area, the person closing or closing the elevator door will always be monitored for safety reasons and the closing operation is interrupted when the closing force exceeds a predetermined first limit value.
  • the closing force limit should in any case be activated and kept at its predetermined first limit.
  • a failure of the personal recognition device can be monitored with the aid of the control or a specially provided monitoring unit. A security of the elevator system is thus always given, in particular also in the case of a failure of components such as the person recognition device.
  • the predetermined area in the vicinity of the elevator door monitored during the closing operation may be an area from which a person can be driven rapidly, i. For example, with one or a few steps, could get into a displacement area in which or along which the elevator door is moved.
  • the monitored predetermined area may include all regions within a certain distance, for example within 0.5 m, within 1 m or within 2 m, of a travel path of the elevator door.
  • the monitored predetermined area may include at least one room within a floor adjacent to the elevator door and / or inside the elevator car.
  • a space within the elevator car and / or a space within the adjacent floor directly adjacent to the elevator door to be moved can be monitored before and / or during the closing of the elevator door. Only if there are no persons in these door-near areas, the otherwise effective clamping force limitation may be modified or switched off.
  • the method proposed herein can be performed fully automated, i. without situation-specific interventions by humans.
  • the recognition of persons within the predetermined area near the door and the closing of the elevator door can be carried out automatically by means of actuators, motors and / or sensors.
  • a lift door closing system suitably configured for this purpose can have a suitable actuator system on an elevator door to be closed in order to be able to open or close it automatically along a travel path.
  • the elevator door can be moved, for example, by an electric motor, pneumatically, hydraulically or in a similar manner.
  • the closing force measuring device provided in the elevator door closing system can determine the force with which the elevator door is currently being moved along the travel path.
  • suitable sensors may be provided on the elevator door.
  • a power consumption of the actuators used to move the elevator door can be determined and conclusions can be drawn from this with regard to currently exerted forces.
  • the person recognition device used in the elevator door closing system can be designed, implemented and arranged in different ways.
  • the person recognition apparatus may be configured such that the detection of whether a person is within the predetermined area near the elevator door is performed by visually monitoring the predetermined area.
  • the person recognition device can be designed, for example, as a camera, in particular as a video camera.
  • visual monitoring may include taking and analyzing images or image sequences, ie monitoring optical properties, preferably in a spectral range visible to humans.
  • Images taken by the person recognition device can be analyzed for presence of persons.
  • different technical measures or algorithms can be used.
  • image contents may be analyzed for the presence of persons of typical contours or the like.
  • movements that are typical for the presence of persons can be recognized in a picture sequence.
  • image or motion comparisons for example, with previously recorded images or image sequences to indicate the presence of people.
  • the detection of whether a person is within the predetermined area near the elevator door can be performed by thermally monitoring the predetermined area.
  • the person recognition device may be formed, for example, as an infrared sensor.
  • the presence of a person can be recognized in this case, for example, due to the radiated heat radiation. Since this heat radiation is generally typical for living beings and differs significantly from those of inanimate objects, a presence of persons can be deduced in this way relatively simply and with high reliability.
  • recognizing a person within the predetermined door-near area may also be performed by monitoring temporal changes within the predetermined area.
  • the person recognition device may be configured, for example, as a motion sensor, in part also as a motion detector.
  • a motion sensor can be understood to mean an electrical or electronic sensor which detects movements in its immediate vicinity.
  • the motion sensor can work in particular as an electrical switch and output corresponding signals, for example, when detecting movements.
  • the motion sensor can work actively or passively.
  • an active motion sensor may emit electromagnetic waves and detect reflected portions of those waves.
  • such a motion sensor may be high-frequency Send out and detect radiation.
  • the motion sensor can act as Doppler radar, ie detect movements due to a frequency shift in reflected radiation.
  • an active motion detector can emit sound waves, in particular ultrasonic waves, and detect reflected components.
  • a passive motion detector can, for example, detect radiation imitated by moving objects, in particular infrared radiation, and infer movements from temporal changes in the detected radiation.
  • the person recognition device may, for example, be arranged in a floor near the landing door, for example at the top or above the landing door, and monitor the area in a floor corridor directly in front of the landing door. Additionally or alternatively, a person recognition device can be arranged within the elevator car and monitor this area. Optionally, a single person recognition device can be provided which monitors both the interior of the elevator car and the area near the door within the adjacent floor corridor.
  • the control provided in the elevator door locking system controls the closing operation of an elevator door taking into account, in particular, information or signals from the closing force measuring device and from the person recognition device.
  • the closing process may initially be triggered on the basis of various criteria, for example by waiting a minimum time since a last detected passage through a light curtain of the elevator car by a passenger.
  • the control starts to activate an actuator of the elevator door to move the elevator door, it is checked by means of the person recognition device, whether at least one person is within the predetermined door-near area.
  • the closing force limit remains activated and the first limit valid in this regard is set to its default value of typically 150N.
  • the closing force measuring device measures the closing force which is currently required for this during the process of the elevator door. If this does not exceed the first limit, the elevator door is completely closed. If the first limit value is exceeded, the closing process is interrupted immediately by the controller.
  • the controller can refrain, for example, from an evaluation of the signals provided by the closing force measuring device and thus temporarily suspend a closing force limitation.
  • the allowable closing force limit may be temporarily raised to a higher, second threshold of, for example, 200 N or more.
  • the controller can for this purpose have a suitable data processing unit and a data storage unit.
  • the data storage unit may store data e.g. electrically, magnetically or otherwise non-volatile or volatile.
  • the first and the second limit value can be stored.
  • the data processing unit may have a processor or a CPU for processing incoming signals from, among other things, the person recognition device and / or the closing force measuring device. In particular, the data processing unit can compare measured actual closing forces with the first or second limit value and, based on this, control or interrupt the closing operation of the elevator door.
  • Fig. 1 shows essential components of an elevator installation with an elevator door locking system according to an embodiment of the present invention.
  • Fig. 1 shows a partial area of an elevator installation 1. Shown is a perspective view from a point of view within a floor 5 of a building. An elevator car 7 of the elevator installation 1 has been stopped on the floor 5 and an elevator door 9 is open.
  • the elevator installation 1 has an elevator door locking system 3, with the aid of which a closing operation of the elevator door 9 can be controlled.
  • the elevator door locking system 3 comprises the closable elevator door 9, an actuator 11, for example with an electric drive for closing and opening the elevator door 9, a closing force measuring device 13, a person recognition device 15 and a controller 17.
  • the elevator door 9 can be displaced along a travel path 10 in order to close and reopen it.
  • the displacement can preferably be linear, so that the travel path 10 is rectilinear.
  • the actuator 11 may in this case be the e.g. Rail-guided elevator door 9 or individual displaceable parts of the same deliberately force to move them along the travel path 10.
  • the closing force measuring device 13 has suitable sensors to detect the force with which the elevator door 9 is currently being moved, for example, during a closing operation.
  • the person recognition device 15 is designed to recognize whether there are currently one or more persons 21 within a predetermined area 19 in the vicinity of the elevator door 9.
  • the person recognition device 15 can monitor the area 19 to be monitored by measuring various physical variables, in particular, for example, visually detectable or thermal measured variables.
  • the person recognition device 15 can be designed as a camera 23, in particular a video camera.
  • the person recognition device 15 comprises two sub-devices 15 ', 15 ", of which a sub-device 15' within the Elevator car 7 is arranged on the ceiling and monitors a portion 19 'within the elevator car 7 and another sub-device 15 "is located above the elevator door 9 in the hallway of the floor 5 and there monitors another area 19".
  • the controller 17 now controls the closing operation of the elevator door 9 taking into account data of both the Sch thoroughlymessvoriques 13 as well as signals of the personal recognition device 15.
  • the controller 17 is designed to detect whether a person 21 within the monitored predetermined area 19 in near the elevator door 9 is located.
  • the controller 17 performs the closing operation of the elevator door 9 in consideration of a closing force limitation.
  • the controller 17 monitors by means of the closing force measuring device 13 continuously or at short time intervals, with which closing force the elevator door 9 is closed. If this closing force exceeds a predetermined limit value, the closing operation is interrupted or vice versa in order not to jeopardize any persons 21 located in the travel path 10 of the elevator door 9.
  • this clamping force limitation limited to a first predetermined limit value is not necessarily performed permanently. Instead, the controller 17 may recognize, taking into account the signals detected by the person recognition apparatus, when no person 21 is within the predetermined area 19. In this case, if, for example, there is neither a person 21 in the area 19 'inside the elevator car 7 nor in the area 19 "directly in front of the elevator door 9, the closing force limitation can be temporarily suspended or limited to a higher second predetermined limit value.
  • the elevator door 9 can be moved with increased forces at least in the event that there are no persons 21 in the vicinity of the elevator door 9. As a result, this can possibly also overcome high opposing forces. This can, for example, for the Case that caused by chimney effects strong air currents in a building high opposing forces on the elevator door 9, this elevator door can still be closed at least then by means of increased forces, if this way no nearby persons 21 are at risk.
  • the trouble-free functionality of the personal recognition device 15 can be monitored in order to ensure that in the event of a failure of the personal recognition device 15, persons 21 are not endangered.
  • Such a monitoring of the person recognition device 15 can also take place in a dedicated, unillustrated monitoring unit.
  • An operation and availability of the elevator installation 1 can thereby be improved without endangering the safety of the elevator installation 1 and its passengers.
