Definitions

  • the invention relates to a method for monitoring the movement of a drivable, one- or multi-part door or gate leaf according to the preamble of claim 1 and a device for carrying out the method according to the preamble of claim 14.
  • Such a method and such a device are known from EP-B1-0 083 947.
  • the monitoring device disclosed therein is based on the basic idea that the actual profile of the force required to drive the door leaf is continuously compared with a target profile over the transfer path. If the difference between the actual profile and the target profile exceeds a predetermined amount, an interrupt signal is generated which switches off the drive of the door leaf or reverses its direction of movement.
  • the target profile is recorded and stored at least once before the gate is put into operation for an unobstructed normal operation along the transfer route.
  • Such a monitoring system already points towards other known monitoring devices, such as flexible ones Beaded electrical contacts, improved hazard protection. Nevertheless, even with such a monitoring device, cases can still arise in which the criterion for generating the interrupt signal is not sufficiently sensitive. If the edge of the door leaf hits soft obstacles, for example, the movement force for moving the door leaf increases more slowly than a hard obstacle, so that a longer period of time passes until the interruption signal is triggered. If, for example, the edge of the door leaf bumps into the lateral groin area of a person who accidentally gets into the path of movement during the movement of the door leaf, the interruption signal from the monitoring device is sometimes not triggered sufficiently early.
  • the object of the invention is therefore to monitor the transfer movement between the open position and the closed position of gates or doors of the type in question as sensitively as possible for a deviation from normal operation.
  • the solution according to the invention consists in that, in addition to the known method, a derivation of the actual profile of a physical operating variable of the door movement after the transfer path is formed at each scanned point and that an interrupt signal is also generated if a criterion according to the determined derivation is not met is.
  • the target course of the relevant physical operating variable is recorded and stored at least once before the gate is put into operation for an unobstructed normal operation along the transfer route.
  • the advantages achieved with the invention are in particular in that the monitoring device is equally sensitive to hard objects and / or soft objects when it hits the gate. Compared to a monitoring device of the generic type, this improvement can be achieved with relatively little effort.
  • the first derivative is preferably formed after the transfer route or according to the time, but higher derivatives can also be used.
  • the difference value to be specified is dependent on the one hand on external influences such as wind influences, slight icing and the like, on the other hand it takes into account minor changes in the outlet resistance.
  • a fixed difference value is predetermined beforehand over the entire movement sequence, but in principle the difference value can also be dimensioned differently over the transfer route, in particular to compensate for the different wind impairments depending on the movement route achieved.
  • the set course and the actual course can be derived from different physical operating variables of the advance movement, but preferably the same physical output variables will be evaluated for both values.
  • the target profile is recorded and stored only after the door has been installed at the place of use and the target change profile is then determined and also stored.
  • the target profile can be newly recorded and saved after certain operating intervals of the door, and a new target change profile can be determined therefrom.
  • the target change history can also be determined and saved once, but it is also possible that the target change history is determined anew during operation with each movement of the door leaf on the basis of the target history.
  • the route-dependent determination of a physical operating variable of the door leaf movement can be carried out in different ways.
  • the driving force of the door leaf is preferably taken as a basis, which in turn can be determined via a direct force measurement or also via a torque measurement.
  • a preferred way of measuring the torque is to determine the angle of rotation between two elastically coupled coupling elements which are connected in series in the course of the driving force path.
  • the transfer path itself is also determined by a suitable measuring device.
  • a pulse generator is preferably used, which is also driven by the drive motor. In conjunction with two switching elements that detect the opening position and the closing position of the door leaf, the momentary position on the transfer line can be determined with the pulse generator within the resolution accuracy of the given pulses.
  • the speed of movement of the door leaf is taken as a measure of a physical operating quantity of the movement.
  • the movement speed is no longer recorded depending on the transfer route, but depending on the time.
  • a speed profile which is also recorded as a function of time, serves as the target profile for an unobstructed normal operation.
  • a tachometer generator or a pulse generator which is driven by the door drive, can be used to measure the speed of movement. While the pulses emitted by the pulse generator still have to be derived in a frequency proportional to the speed, the tachometer generator already supplies a voltage proportional to the speed of movement of the gate.
  • the device consists of a door drive, a measuring element for measuring the transfer path, a measuring element for measuring a physical operating variable of the gate movement, a control unit with memories for the measured variables and a differentiating element.
  • control unit consists of a microcontroller on which corresponding memories and AD converters are already integrated.
  • the differentiator is preferably also implemented on the microcontroller in the form of software logic. But it is also conceivable that the differentiator consists of an analog differentiator, the signal of which is also fed to an AD converter. In any case, the differentiator must be designed so that the current derivative of the input signal in question is reliably determined regardless of short-term noise disturbances.
  • the door drive consists of an electric motor.
  • the power supplied by the electric motor can be used directly as a measure of a physical operating variable of the door movement. If the voltage is constantly applied, the current supplied to the electric motor can also serve as the basis for a physical operating variable, the current measured thereby being approximately a measure of the torque delivered by the electric motor.
  • the interruption signal generated by the control unit results in the electric motor being switched off.
  • the drive direction of the door drive is reversed due to an interruption signal, which can be done in a suitable electric motor by reversing the polarity of the supply voltage or by a suitable gear.
  • the garage door from FIG. 1 has two vertical struts 1, at the upper end of which two track rails 2 are connected, in which the door leaf 3 is guided.
  • the door leaf 3 is further articulated to the struts 1 with a linkage, not shown, so that the door leaf can be opened and closed with an overhead movement.
  • compensating springs are provided which largely compensate for the dead weight of the door leaf during the movement and which keep the door leaf defined in its end positions.
  • the drive system designated 4 consists overall of a drag chain drive with a drag chain 5 to which the door leaf 3 is articulated and which is guided over the deflection roller 6 and over a drive roller, not shown.
  • the drive roller is located in the drive unit 7 and is driven by the electric motor 9 via a gear.
  • a pulse generator 8 which is mounted on an elastic coupling and which emits a pulse after a certain angle of rotation.
  • control unit 10 which consists of a microcontroller with integrated memory and AD converters.
  • the output signal of the control unit 10 leads to an amplifier 11 which supplies the electric motor 9 with the necessary power via a current measuring element 12.
  • the input variables of the control unit include the measurement variables 8a and 12a, the switching signals 13a and 14a and input signals 15, which are not specified in more detail, and which may include signals from an operating unit and also a voltage supply.
  • the signal 8a of the pulse generator is evaluated by the control unit in connection with signals from the switching elements 13 and 14.
  • the switching elements are actuated by the door leaf 3 in its end positions, that is in each case in the vertical and in the horizontal position.
  • the signals 13a and 14a therefore each serve as start-stop signals in order to ensure reliable integration of the signal 8a.
  • FIG. 2 shows a possible embodiment of the pulse generator 8.
  • a coupling is shown, which is provided between the drive wheel of the drag chain 5 and the output of the drive motor 9.
  • the driven coupling half 20 is designed as a torsionally flexible coupling member with a radial intermediate layer between the toothing and the hub, for example in the form of a rubber ring 21.
  • the driven coupling half 22 has teeth 23 on its radial circumference, which are scanned by the inductive transmitter 24. When the clutch rotates, the inductive transmitter 24 emits corresponding pulses due to the periodic change in the inductance.
  • the target curve of the motor current is recorded for an unobstructed normal operation depending on the transfer route.
  • the signals 8a and 12a are read into the microcontroller via AD converters at the same sampling times and stored in such a way that an assignment of values of the same times is possible.
  • the target curve thus recorded is stored in the EPROM so that the values can be loaded into the main memory each time the microcontroller is reset.
  • an actual profile of the motor current depending on the transfer path is recorded in accordance with the target profile. For each actual value recorded, a calculation procedure is run through before the next actual value is recorded, that is to say within a sampling period, which checks whether there are inadmissible deviations from the target curve and whether an interrupt signal must be generated accordingly.
  • each recorded actual value is first compared with the corresponding target value for the same values of the transfer route. If the actual value deviates from the target value by a predetermined amount, an interrupt signal is generated by the microcontroller, which results in the drive direction of the door leaf being reversed.
  • the derivation is formed in a next step for the currently recorded actual value depending on the transfer route.
  • Various methods are conceivable for this, the simplest of which consists in forming a difference between the currently recorded actual value and the previously recorded actual value. If the actual values are particularly noisy, the previous values may need to be smoothed before the difference is formed. For this purpose, a certain number of previously recorded actual values are interpolated with a predetermined function before the interpolated function Derivative is formed.
  • the currently determined derivation is included in an actual change history, which is compared with a target change history. This target change history was likewise determined and stored before start-up based on the target history already recorded using the method just described. If the actual change value deviates from the target change value by a predetermined amount, an interrupt signal is generated, which in turn results in a reversal of the drive direction of the door leaf.
  • the already known criterion between the target profile and the actual profile is supplemented by an additional criterion between the target change profile and the actual change profile, which allows a more precise assessment for generating an interruption signal.
  • the target curve can be compared more and more precisely with the actual curve by forming further derivatives.
  • the limit here is the noise behavior of both signals already mentioned, as a result of which a minimum tolerance range between the actual profile and the target profile is required so that the interrupt signal is not triggered undesirably.
