Definitions

  • the invention firstly relates to a method for operating an elevator control device. Furthermore, the invention also relates to a computer program for implementing the method and to a computer program product with such a computer program and to a device, for example an elevator control device, having such a computer program as means for carrying out the method.
  • the operation of an elevator installation by means of an elevator control device and at least one drive controlled by the elevator control device for moving at least one elevator car is known per se.
  • the elevator control device controls the movement of at least one elevator car in at least one elevator car shaft.
  • the or each elevator car - the following description is continued without waiving further generality using the example of an elevator car - drives individual floors under the control of the elevator control device and in each case executes a floor stop at a predetermined stop position.
  • the predetermined stop positions are due to the number of floors that connects the elevator car shaft and due to a lower edge of the individual floor doors.
  • a holding position is then that position of the elevator car in the elevator car shaft, in which a lower edge of the landing door and a lower edge of the car door are aligned or at least substantially aligned.
  • the drive controlled by the elevator control device for moving the elevator car is usually a drive in the form of an inverter fed by a supply network with an electric motor connected downstream of the converter.
  • inverter By generally known per se control of the motor-side part of the inverter (inverter) succeeds influencing the electrical power reaching the electric motor by frequency and amplitude, so that in particular the speed of the electric motor and thus the resulting speed of movement of the elevator car in the elevator car shaft influenced and predetermined by the elevator control device can be.
  • a position information referred to hereinafter as an actual position is compared with a stop position predetermined for the floor stop.
  • the position information used as actual position receives the elevator control device from the drive. These are, for example, data on the speed and the rotational position of the drive. Such data are provided in a manner known per se by electric drives for retrieval by an external control, here the elevator control device.
  • the holding position is reached.
  • the elevator car is then in a position where the car doors can be opened to the respective floor to allow passengers to get out or waiting passengers to board.
  • An object of the invention is to specify a method for operating an elevator control device provided for controlling and monitoring the movement of at least one elevator car, which already improves the accuracy when approaching a respective holding position at the floor stop and / or subsequent detection of the landing accuracy Successful floor stops allowed.
  • This object is achieved with a method for operating an intended for controlling and monitoring the movements of at least one elevator car elevator control device having the features of claim 1.
  • a total error in the form of a deviation of an actual position of the elevator car and a position of the elevator car assumed as an actual position is determined.
  • the assumed as actual position position - hereinafter referred to briefly as actual position - is determined based on drive data of the elevator car, so based on data that are available as speed, angular position and the like of a controlled by the elevator control device drive and / or inverter. It should be emphasized, however, that the actual position managed by the elevator control device is an assumed position.
  • the total error expresses a deviation between this actual position and the actual position. This total error can be evaluated statistically to check whether floor levels are done properly and the respective holding positions are approached with the actually desired land accuracy.
  • a Vorhaltwert is determined based on the total error.
  • the resulting derivative value corresponds to the underlying total error.
  • This Vorhaltwert is taken into account in a next executed by the elevator control device for starting the respective holding position comparison of actual position and holding position in addition to the actual or the holding position.
  • a derivative value determined on the basis of the respective overall error is used for each floor of a building.
  • This allows the consideration of dynamic influences on the movement of the elevator car in the elevator car shaft.
  • the free length of the suspension cables and a dependent possible dynamic change in length will have an influence on a respective accuracy with which a holding position can be approached. Because these influences are correlated with the free length of the supporting cables and thus with the respective corresponding floor, such influences can be taken into account comparatively easily, if for each floor of the respective Building or at least individual floors of the building for this on the basis of the respective total error determined derivative value, so a floor-specific Vorhaltwert is used.
  • At least two predefined values determined on the basis of the respective total error are used.
  • These at least two Vorhaltives are a first floor specific Vorhaltwert for an upward drive before the floor stop and a second floor specific Vorhalt value for a downward drive before the floor stop. This allows for consideration of influences which depend, for example, on mass acceleration, mass inertia and gravitation. In general, it can be expected that a floor stop following an uphill ride will result in a different overall error than following a previous descent. By taking into account different Vorhalthong depending on the previous direction of travel, the method can be taken into account.
  • At least four control values determined on the basis of the respective total error are used for at least individual floors.
  • These at least four Vorhaltives are a first floor specific Vorhaltwert for an upward drive before the floor stop and an upward drive to the floor stop, a second floor specific Vorhalt value for a down trip before the floor stop and a down trip to the floor stop, a third floor specific Vorhaltwert for an up drive before the floor stop and a downstroke after the floor stop and a fourth floor specific Vorhaltwert for a downward drive before the floor stop and an upward drive to the floor stop.
  • These different retention values take into account for each floor the possible driving situation of the elevator car, that is, in which direction of travel the position of the floor stop is reached and in which direction the journey is continued.
  • the above-mentioned object is also achieved with an elevator control device, which is set up to carry out the method and individual or all embodiments of the method.
  • the invention is preferably implemented in software.
  • the invention is thus on the one hand also a computer program with by a computer, namely the elevator control device executable program code instructions and a storage medium with such a computer program, so a computer program product with program code means, and finally an elevator control device, in the memory as means for carrying out the method and its Embodiments such a computer program is loaded or loadable.
  • the method described here and below is carried out automatically by the elevator control device in that the elevator control device controls the elevator car so that it moves to individual floors in a building and thereby at a predetermined stop position each executes a floor stop.
  • a total error in the form of a deviation of an actual position of the elevator car and a position of the elevator car assumed as an actual position is determined. Based on the total error, a derivative value is determined. This is taken into account in a comparison made by the elevator control device for starting the respective holding position comparison of actual position and holding position in addition to the actual or the holding position.

  • the elevator control device 16 controls the drive 22 accordingly and the movement ends when the elevator car reaches a holding position known with respect to the respective destination floor.
  • Such hold positions are expressed in terms of numerical values, and because they result, for example, from a fixed position of a lower edge of a respective floor door, are given to the elevator controller 16 as constant values.
  • FIG. 2 shows a known per se comparator 24 with two inputs 26, 27 for comparing the input signals supplied there and for generating an output signal 28 depending on the result of the comparison.

  • the second curve 32 represents a position of the elevator car 14 assumed on the basis of drive data, in particular converter data.
  • the position of the elevator car 14 assumed on the basis of the drive data is the already mentioned actual position, since only this position is known to the elevator control device 16 and is accordingly transmitted by the elevator control device 16 assumed as actual position.
  • a position indicator designated in the technical terminology as a floor flag which defines the holding position provided for the respective floor 20.
  • a position indicator is, for example, a forked light barrier, which cooperates with a switching lug which dips into the slot of the forked light barrier, as described in US Pat EP 0 483 560 B is described.
