Definitions

  • the invention relates to a method for operating an elevator installation and to such an elevator installation.
  • the elevator doors of the elevator system are actuated by a door drive via a travel curve.
  • Lift doors usually consist of a car door which is connected to an elevator car and a plurality of shaft doors, which are arranged on floors of a building and provide access to the shaft of the elevator.
  • shaft doors When opening and closing the car door and a shaft door are connected to each other via a clutch and moved together, by the mounted on the elevator car door drive.
  • Elevator doors as used, for example, in high-performance elevators, must meet various requirements. For example, the customer requires the shortest possible door closing times in order to achieve high transport performance.
  • EP0548505B1 discloses a method for rapidly opening and closing the elevator doors according to a travel curve.
  • the travel curve contains information on the duration and speed of opening and closing the elevator doors as well as on the kinetic energy of the elevator doors during these operations.
  • the elevator doors can be closed with more or less force and time, which impairs the transport performance.
  • US3822767A teaches detecting the wind speed prevailing in the hoistway and a proportional adjustment of the size of the closing force of the door drive moving the elevator doors to the strength of the wind speed prevailing in the hoistway.
  • a driving curve usually consists of several phases, namely an acceleration phase, a sliding phase and a deceleration phase, wherein there are different closing forces only in all three phases.
  • the elevator doors are moved with high closing forces, but in the sliding phase, the elevator doors are only moved with low closing forces. Therefore, the travel curve is not optimally adapted to the pressure conditions when opening and closing the elevator doors by a proportional adjustment of the size of the closing force of the door drive.
  • an excessively fast opening and closing of the elevator doors unnecessarily high consumption of electricity and leads to rapid wear of the elevator doors, which in turn increases the maintenance costs of the elevator system and also affects the availability of the elevator system.
  • Object of the present invention is to provide an optimum under even pressure conditions driving curve for the opening and closing of elevator doors. This task should be realized with proven elevator construction techniques.
  • the invention teaches a method for operating an elevator installation and an elevator installation with elevator doors which are actuated in accordance with a travel curve. Pressure conditions and / or air currents are detected. From a plurality of driving curves, an optimum driving curve with respect to the detected pressure conditions and / or air currents is determined.
  • the advantage of the invention is that the travel curve is optimally determined at any time, even under adverse physical conditions, ie with large pressure fluctuations and / or in strong draft, so that the transport performance of the elevator system experiences as little impairment as possible.
  • a control of the door drive has at least two different travel curves for opening and closing the elevator doors. Depending on the physical conditions, one or the other driving curve is used.

  • the elevator consists of a group of elevator cars, which are moved in an open shaft next to each other and / or one above the other and which thereby generate changing pressure conditions and / or air flows in the shaft.
  • operating data of a building air conditioning system and / or a shaft ventilation are taken into account for determining the air flow.
  • building-specific parameters such as the height of the building, the number of floors, the quality of the building insulation, the number of open and / or closed entrances and windows, the type of building roof, etc. are advantageously taken into account.
  • a desired range is defined in which predefined pressure conditions and / or air flows prevail, in which a clutch of an elevator cage door folds into the elevator movement position prior to the complete locking of an elevator door.
  • a desired range is defined, prevail in the predefined pressure conditions and / or air currents, in which a departure of the elevator car is possible without completing the locking of the elevator door completely.
  • the elevator car leaves a floor before the elevator doors are fully locked, which increases the transport performance.

  • the evaluation unit 13 evaluates the data using a processor and software.
  • the optimum travel curve can be determined based on calculations based on the physical conditions. In this case, an infinite number of driving curves are available for the elevator doors 4, 6.
  • the optimum travel curve can also be called from a memory and thus be determined from a finite selection.

  • Evaluation unit 13 and elevator control 14 can also be realized in a single device. It is also possible to store the travel curve to be used in the elevator control 14 and to transmit only information about the travel curve to be used to the elevator control 14.
  • FIGS. 4A and 4B show several embodiments of driving curves.
  • a travel curve describes the opening and closing characteristics of the elevator doors 4,6.
  • the elevator doors 4, 6 consist of at least one car door 6 and per floor 2 of at least one shaft door 4.
  • the travel curve can be represented differently.
  • Fig. 4A shows the speed when opening or closing the elevator doors 4,6 as a function of time.
  • Fig. 4B shows the performance of a door operator 22 when opening or closing the elevator doors 4,6 as a function of time.
  • the maximum speed which the elevator doors 4, 6 reach may depend on the maximum value of the kinetic energy which the elevator doors 4, 6 may reach for safety reasons.
  • An optimum travel curve allows the elevator control 14 to lock the elevator doors 4, 6 as quickly as possible and to leave the floor 2 as quickly as possible, even in adverse physical conditions.
  • determining the optimum driving curve in addition to the physical conditions, door drive 22, mass, door leaves, etc. also play a role.
  • the closing time of the lift doors 4,6 can be reduced by approx. 15-20% thanks to an optimum travel curve.
  • the saved Time depends on the mass of the door. Depending on the ratio of the engine torque and the mass of the lift doors 4, 6 to be moved, this can vary by ⁇ 10%.
  • a driving curve consists of three phases (I-III).
  • the acceleration phase phase I
  • the elevator doors 4, 6 are accelerated to a set speed (P setpoint ) of the door drive 22 up to a set speed (v setpoint ).
  • P setpoint set speed
  • v setpoint set speed
  • phase II the elevator doors 4,6 are more or less unaccelerated with low drive power in motion.
  • phase II with a low drive power takes the longest, since no adverse physical influences disturb the door closing process.
  • the setpoint speed (v setpoint ) can be kept short.
  • the phase II lasts the same length as in the curve 1 .
  • the setpoint speed (v setpoint ) can not be maintained.
  • the unaccelerated phase II is prematurely terminated by the braking of the elevator doors 4, 6 due to adverse physical influences.
  • the drive power over the target power (P target ) is increased, since it is known that adverse physical Influences are responsible for the resistance.
  • the curve 4 therefore coincides in its closing time with the curve 1 and 2.
  • phase III the elevator doors 4, 6 are braked again by the motor drive.
  • the curves 1, 2 and 4 must be braked equally strong because their speed at the end of phase II is still v desired .
  • the curve 3 has a lower speed, thereby increasing the door closing time.
  • phase II may not be present at certain driving curves. With an optimal driving curve, increased drive power in the sliding phase or even the deceleration phase can occur.
  • the door drive 22 provides in the normal case (curve 1) both in the acceleration (I) as well as in the deceleration phase (III) of the door closing amount of the greatest power.
  • increased drive power is required in adverse physical conditions, for example. In poor pressure conditions or strong air currents.
  • the drive power is up-regulated according to the poor physical conditions up to the maximum power (curve 2) . If this maximum value is reached and the resistance for the car door 6 increases further, the speed of the car door 6 (curve 3) slows down .
  • the evaluation unit 13 provides the calculated or stored travel curve. According to the travel curve of the evaluation unit 13, the elevator control 14 reacts to adverse physical conditions by increasing the drive power in order to keep the door closing time optimally low. Thus, without jeopardizing the safety of persons or things, the drive power can be increased above the set point ( curve 4 ), since the cause of the increased power requirement lies in the adverse physical conditions and is thus known.
  • FIGs. 5A and 5B show an embodiment of an elevator door drive device 20 with a coupling 21 of a car door 6 to a shaft door 4.
  • the clutch 21 can be moved by means of a clutch drive 24 via a coupling drive means 25 independently of the door drive 22 and the position of the elevator doors 4,6.
  • the clutches 21 can already be folded into the elevator position in order to start immediately at the time of locking the elevator doors 4.6 with the departure of the elevator car 5.
  • the clutch 21 remains mechanically connected to the hoistway door 4 until it is locked and only then is folded into the elevator position.
  • the length of the coupling 21 can be maintained so that the departure of the elevator car 5 can already be started before the elevator doors 4, 6 are completely locked. Since the lock of the hoistway door 4 and partly of the car door 6 is absolutely necessary for safety reasons, the departure of the elevator car 5 can not begin until it is ensured that the elevator doors 4, 6 are locked before the coupling 21 as a guide, the mechanical contact with the elevator doors 4,6 breaks off.
  • the elevator car 5 must be stopped by an emergency stop.
  • the shaft door 4 can be moved into its locking by the remaining mechanical contact.
  • the guide length of the clutch 21 must therefore be sufficient to cover the track for the acceleration as well as for a possible emergency stop the premature departure can. This means that there must still be a mechanical guide contact between the coupling 21 and shaft door 4.
  • the emergency stop can be done with appropriately adapted acceleration. If the travel curve is suboptimal, this leads to an extension of the door closing times and / or a reduction in the transport performance of the elevator installation 1.
  • the control of the clutch 21 can be done in various ways, so the clutch 21 may, for example, be provided via a clutch drive means 25 with its own clutch drive 24. It is also conceivable that the coupling 21 directly with a door drive means 23rd is mechanically connected and thus moved by the door drive 22.
