Definitions

  • the present invention relates to sensing the position of a door.
  • An example of an application of the invention is a door operator for tracking the position of a garage door curtain such as in a roll -up garage door, tilt door or sectional door.
  • the invention also has application in determining the position of a door in a sliding or swing gate such as in driveway gates.
  • Domestic and industrial garage doors are known to be provided with motor driven door operator mechanisms to automatically open and close the door.
  • a position sensor is required to determine the position of the door to avoid driving the door beyond fully open and fully closed limits.
  • the position sensor is used to feed back a position of the door to a controller of the door opener.
  • Known door openers use micro-switch position limit switches or shaft encoder counters or optical sensors to determine the door position.
  • a problem with known door operators is if there is an electric power supply failure, and the door is required to be manually opened or closed then there must be a physical disconnection of drive train between a drive motor and the door, as the mechanical advantage of the drive train is too great for a person to overcome by manually holding the door and manually attempting opening or closing. Thus when electric power is restored it is necessary to make a drive train reconnection if the door opener is to again perform opening and closing. Unless there is direct re- engagement of the drive train in the exact same position as when the disconnection occurred, there will be incorrect sensing of the fully open and fully closed positions of the door. Complicated systems have been devised in the past to ensure correct position re- engagement and/or suitable adjusting of datums, so that the door will stop at the intended fully open or fully closed positions.

  • the digital signal processor 160 is adapted to receive an analogue detection signal received from the hall array sensor 150 and to process the analogue signal.
  • the analogue signal is converted to a digital signal and analysed to determine the angular position and direction of rotation of the polarized magnet 115. This information is output as a digital signal for storage in memory or use by the door operator controller 130.

This enables the set open position and set closed positions to be re-established from the resolution of the sensor, and the door stopped at those set positions when driven by the motor.
  • An advantage of using a sensor of the type that has an active element which rotates less than 360° is that no battery backup is required to ensure the door position is recorded in memory or tracked during a power failure to - li the door operator.

  • a further advantage of using an active element and a detector, such as a magnet and a hall array sensor, is that the sensor is not prone to interference due to dust, insects or humidity. Further, as this type of sensor is contactless the sensor is not prone to degradation due to mechanical wear and tear. Thus, the sensor is robust and suitable for use in a typical garage environment prone to dust and insects.
  • the sensor requires an adequate resolution to equate the angular rotation of the magnet to the distance of travel required for the door.
  • the required resolution may vary based on the distance of travel for the particular door application. For example a sensor having a resolution 1024 positions per revolution can determine the magnet's angular position with a resolution of about 0.35° and this resolution may be sufficient for application in an embodiment such as a swing or sliding gate having a required travel distance of travel of 1.5m. This translates to an accuracy of 1.4mm increments.
  • the sensor may require a resolution of around 4096 increments in 360°. This translates to an accuracy of 1.2mm increments of the door curtain movements. In practice such accuracy is sufficient for swing or sliding gates, and roll up, lift or sectional doors.

Abstract

L'invention concerne un ensemble détecteur pour une commande de porte doté d'un moteur (501), d'un organe de transmission, et d'un contrôleur (130). L'ensemble détecteur comprend un arbre d'entrée (226) pouvant être raccordé à l'organe de transmission afin de tourner avec celui-ci lorsque la porte s'ouvre et se ferme, même lorsque l'organe de transmission est dégagé du moteur. Un aimant (215) est couplé pour tourner avec l'arbre d'entrée (226) et son orientation est déterminée par un capteur fixe (218) afin de détecter de façon précise la position de la porte. L'aimant (215) présente une rotation relative inférieure à 360 degrés sur toute la portée de la course de la porte. Ainsi, lorsque l'organe de transmission est déconnecté par un embrayage à commande manuelle, l'aimant (215) tourne avec le mouvement de la porte de sorte que, lorsque l'entraînement est reconnecté, le contrôleur (130) soit en mesure de déterminer immédiatement la position absolue de la porte.
