Definitions

  • the invention relates to a method for monitoring the movement a drivable, single or multi-part door or Door leaf according to the preamble of claim 1 and one Device for performing the method according to the preamble of claim 14.
  • Such a method and such a device are out EP-B1-0 083 947 known.
  • the monitoring device disclosed therein is based on the basic idea that the actual course of the required force to drive the door leaf over the Transfer route continuously with a target course is compared. Exceeds the difference between Actual course and target course a predetermined amount, so an interrupt signal is generated which drives the Switches off the door leaf or reverses its direction of movement.
  • the target course is at least once before commissioning of the gate for an unobstructed normal operation along the Transfer line recorded and saved.
  • Such a monitoring system already points towards others known monitoring devices, e.g. under compliant Beaded electrical contacts, an improved one Protection against danger. Nevertheless, even with such Monitoring device still occur in cases where the criterion not sufficient to generate the interrupt signal is sensitive. If the edge of the door leaf hits e.g. against soft obstacles, this increases the power to move the door leaf towards a hard obstacle slower, so that up It takes a long time to trigger the interrupt signal. If the edge of the door leaf hits e.g. in the side Groin area of a person unintentionally during the Movement of the door leaf gets into its path of movement, so the interruption signal from the monitoring device sometimes not triggered early enough.
  • US 5,051,672 describes an automatic window / door system a pressure sensor and a defector ice for evaluation the pressure change.
  • the object of the invention is therefore the transfer movement between the open position and the closed position of gates or Doors of the type in question to a deviation from normal operation to monitor as sensitively as possible.
  • this is Task according to the characterizing features of Claim 1 solved.
  • the solution according to the invention exists in that in addition to the known method on each sampled Point a derivation of the actual course of a physical Operation size of the gate movement after the transfer line is formed and that an interrupt signal even then is generated if a criterion according to the determined derivative is not fulfilled.
  • the target course of the relevant physical Company size is at least once before commissioning of the gate for an unobstructed normal operation recorded and stored along the transfer route.
  • the advantages achieved with the invention are in particular in that the monitoring device when the gate hits on hard objects and / or soft objects alike is sensitive. Opposite a monitoring device this improvement can be of the generic type achieved relatively little effort.
  • the difference value to be specified around which the actual change history must deviate from the course of change of target to the obstacle case on the one hand, signaling is from external influences such as wind, minor icing and the like dependent, on the other hand it takes minor changes into account Sag resistance.
  • a fixed difference across the entire movement previously determined but in principle the difference value can also dimensioned differently across the transfer line be, in particular to compensate for the achieved Movement distance different wind impairment.
  • the target course and the actual course of different physical operating parameters of the advance movement be derived, but it is preferable to use the for both values evaluate the same physical output variables.
  • the target course only recorded after installation of the gate at the place of use and saved and then the target change history determined and also saved.
  • This can actually occurring operating conditions under normal conditions with the actually prevailing environmental influences in a more realistic way Consider wise.
  • the operating conditions due to wear or the like can change over time the target course after certain operating intervals of the door newly recorded and saved and from it a new target change history be determined.
  • the target change history can also be determined and saved once, but it is also possible that the target-target change history during of operation with every movement of the door leaf of the target course is redetermined.
  • the route-dependent determination of a physical company variable the door leaf movement can be done in different ways.
  • the driving force of the door leaf is preferably used as a basis, which in turn via a direct force measurement or also can be determined via a torque measurement.
  • the way of measuring the torque is the twist angle between two elastically coupled together in the train of the driving force path connected coupling elements to investigate. But it can also be done in a known manner the power of an electric drive motor or at constant monitor the applied voltage.
  • a pulse generator is preferably used, which is also driven by the drive motor becomes.
  • the opening position and detect the closing position of the door leaf can use the pulse generator to determine the current position on the transfer line within the resolution accuracy of the given Impulses are determined.
  • the speed of movement of the door leaf as a measure of one physical operating size of the movement is taken.
  • the movement speed is no longer dependent on the Transfer route, but added depending on the time.
  • A also serves as a target course depending on the Time-recorded speed curve for an obstacle-free Normal operation.
  • For measuring the speed of movement can serve a tachometer generator or a pulse generator that are driven by the gate operator. While that of that Pulse generator still emitted pulses in a to speed proportional frequency must be derived, the Tachogenerator already one for the speed of movement of the gate proportional voltage.
  • the device consists of a gate operator, a measuring element for measuring the transfer route, a measuring element for measuring a physical operating variable the door movement, a control unit with memory for the measurands and a differentiator.
  • the control unit exists from a microcontroller on which the corresponding memory is already located and AD converter are integrated.
  • the differentiator is preferably also on the microcontroller in the form of a Software logic implemented. But it is also conceivable that Differentiator consists of an analog differentiator, whose signal is also fed to an AD converter. In in any case, the differentiator must be designed so that the current derivation of the relevant input signal independently is reliably determined by short-term noise disturbances.
  • the door drive from an electric motor.
  • the power supplied by the electric motor can be used directly as a measure of a physical company size the gate movement can be taken.
  • constant pressure Voltage can also be supplied to the electric motor Electricity serve as the basis for a physical company variable, whereby the current measured approximately a measure of the given torque of the electric motor.
  • the interrupt signal generated by the control unit Switching off the electric motor results.
  • the drive direction of the door operator is due an interrupt signal reverses what is appropriate at a Electric motor by reversing the polarity of the supply voltage or can be done by a suitable gear.
  • the garage door from FIG. 1 has two vertical struts 1 whose upper end is followed by two tracks 2, in which the door leaf 3 is guided.
  • the door leaf 3 is still with a linkage, not shown, articulated to the struts 1, so that the door leaf opens with an overhead movement and lets close.

  • the drive roller is located in the drive unit 7 and is driven by the electric motor 9 via a gear.
  • a pulse generator is also driven by the electric motor 9 8, which is mounted on an elastic coupling and the emits a pulse after a certain angle of rotation.
  • control unit 10 which consists of a microcontroller with integrated memory and AD converters exist.
  • the output signal of the control unit 10 leads to an amplifier 11 which the electric motor 9 via Current measuring element 12 supplies the necessary power.

  • the switching elements are from the door leaf 3 in its end positions, in each case in a vertical and in a horizontal position, actuated.
  • the signals 13a and 14a therefore each serve as Start-stop signals to reliably integrate the signal 8a to ensure.

  • the actual value deviates from the target value by one fixed amount, an interrupt signal from the Microcontroller generates a reversal of the drive direction of the door leaf.
  • the derivation depending on the transfer route educated.
  • the simplest is to form a difference between the currently recorded actual value and the previously recorded one Actual value. If the actual values are particularly noisy, then If necessary, smoothing the previous one before forming the difference Values necessary. To do this, a certain number previously recorded actual values with a specified function interpolated before the interpolated function Derivative is formed.
