Definitions

  • the present invention relates to a passage barrier with a first and a second locking element, wherein the locking elements are each movable between an open position and a closed position, with drive means with which the locking elements are driven from one to the other position, with a control, by means of which the drive means are controllable, and with a sensor unit connected to the control unit.
  • the invention relates to a method for operating the passage barrier, wherein a first and a second blocking element are moved by means of drive means between an open position and a closed position, wherein the drive means are controlled by a controller.
  • Passage barriers of the generic type are widely used in the prior art, for example, to be able to regulate the access or access to protected and / or paid areas. Passage barriers are often used for example in public transport, airports, in particular at security gates, but also in public facilities such as swimming pools, sports facilities and the like. They serve, among other things, to allow access by persons only in the presence of an authorization or to separate the access of persons.
  • a passage barrier in the form of two opposing, pivotally driven door wings are provided which are automatically pivoted to an open position when a person holding a permission wishes access and wants to pass through the passage barrier.
  • the person enters this in a test unit with which an authorization can be checked, an authorization card, whereupon, when the validity of the control unit connected to the control unit controls the drive means, so that the door leaves of the swing doors are pivoted to the open position.
  • the person can then open the Pass through barrier.
  • the door leaves After passing through the passage barrier, the door leaves are automatically closed again.
  • the passage of the passage barrier is detected by the sensor unit and a corresponding signal is transmitted to the controller. After passing through the passage barrier, the blocking element is moved to the closed position.
  • a light barrier is provided, by means of which a current position of the person can be detected at points.
  • the detection is insufficient because the light barrier has a very small, substantially linear detection range. Outside the coverage area, no one person can be detected.
  • the light barrier provides false detection values by the action of extraneous light. It may therefore come to erroneous controls by the controller.
  • the energy that can be transmitted to the door leaves by the drive means is limited. Is a person when opening or closing a door in the swing range of this door, because it has changed its direction of movement, has stopped, or the like, the door will abut this person and end his movement due to the limited energy, so that the person as little hurt as possible.
  • the passage barrier thus has a passive safety.
