Definitions

  • the invention relates to a control electronics for a DC operated door opener and a supply unit for a DC operated door opener.
  • electrical door openers can be controlled with direct current or alternating current.
  • alternating current creates a buzzing sound, which is perceived as disturbing, especially if the controlled door for a long time, z. B. several hours, to be unlocked.
  • driving with direct current already causes a very low preload on the door opener trap that the door opener jammed and the door is not released. Even the preload caused by a door seal may be enough to jam the door opener, resulting in the door not being opened.
  • a control electronics for a DC operated door opener according to the invention has a lighting device, which is a to the Door opener applied DC voltage can pulse or pulse at least during a certain period of energization of the door opener.
  • the possible preload in door-openers operated with direct current is increased without a hum occurring in accordance with an alternating current current occurring.
  • the certain period of time is advantageously at the beginning of the energization.
  • the specific period of time according to the invention advantageously lasts approximately between 0.2 seconds and 10 seconds, preferably between about 0.2 seconds and 5 seconds, more preferably about 1.5 seconds.
  • a combination of these two advantageous embodiments of the invention has the advantage that the door opener opens safely even at an increased preload, after which the preload no longer needs to be considered and by the DC operation, a very quiet operation is achieved.
  • the pulsed current can according to the invention z. B. only then take place when the control electronics has detected a blocking of the door opener, whereby according to the invention a DC operation can be done without pulses, if this is sufficient to open the door.
  • the pulsing of the DC voltage advantageously takes place at a frequency approximately between 10 Hz and 200 Hz, preferably approximately between 10 Hz and 100 Hz, more preferably approximately 50 Hz or 60 Hz.
  • These frequencies ensure that the door opener actuated according to the invention does not jam and in particular the further preferred embodiment offers the advantage that a user does not hear him unfamiliar humming or whistling, but a sound corresponding to the usual power hum.
  • a supplied supply voltage for the door opener is pulsed during a certain period of time and otherwise forwarded unchanged to the door opener, in particular by the lighting device.
  • the control electronics according to the invention can be easily switched between a conventional power supply and a conventional door opener and is activated by the conventional control, after which the advantages of the invention without further Dazutun be achieved.
  • the lighting device is a transistor, preferably a MOSFET.
  • control electronics on an oscillator device, which controls the lighting device during a certain period of time so that a pulsed supply voltage is applied to the door opener.
  • the oscillator device in a further advantageous embodiment of the invention comprises a Schmitt trigger connected as an oscillator.
  • control electronics on a timer, which determines the beginning and duration of the particular period of time.
  • the time control device comprises in a first further advantageous development of the invention, a first timer, which determines the beginning of the specific period of time after supplying a supply voltage for the door opener.
  • the first timer comprises in a still further advantageous embodiment of the invention, a Schmitt trigger, at the input of a switched against the supply voltage for the door opener capacitor and a resistor connected to ground are connected.
  • the time control device in a second further advantageous embodiment of the invention comprises a second timer, which determines the duration of the particular period of time.
  • the second timer in a still further advantageous embodiment of the invention comprises a Schmitt trigger, at its input connected to the supply voltage for the door opener resistor and connected to ground capacitor are connected.
  • Schmitt triggers In such an embodiment of all three previously mentioned modules with Schmitt triggers an advantageous series connection of the three modules is possible, as will be described in detail below. Furthermore, a very compact construction is possible. In a self-locking MOSFET as a lighting device Schmitt triggers are advantageously designed as inverting Schmitt trigger.
  • control electronics on a voltage regulator for supplying the control electronics from a supply voltage for the door opener.
  • control electronics according to the invention the time constants of which generally result from the supply voltage applied thereto, can be used for door openers operating with very different voltages, without any need for changes or adjustments.
  • a supply unit according to the invention for a DC-operated door opener has a control electronics according to the invention.
  • control electronics can also be connected directly to an existing supply voltage (DC voltage).
  • FIG. 1 the basic activation of a door opener T ⁇ is shown.
  • a power supply unit 1 supplies a door opener control with the necessary supply voltage via a connection 5.
  • the connection 5 goes to a timer 2 whose output signals go via a connection 6 to an oscillator 3.
