Definitions

  • the invention relates to an access control device with an electric door opener on the one hand, which has a swivel latch, a releasable latch for the swivel latch, an electromagnet interacting with the latch and a status indicator for monitoring the open / closed state of the access concerned, and a control center on the other hand, which is connected to the door opener via a supply line and to the status detector via a signal line.
  • Such access control devices are known to be used to secure and monitor closed areas in buildings and outdoors. It is to be ensured that only authorized persons enter or leave this area, the control being carried out continuously or being restricted to certain time segments.
  • the entrances and exits are provided with mechanical actuators, for example turnstiles, doors or gates. They are controlled by electrical door openers that are connected to a control center. To monitor the status of the actuator there are also feedback devices which report the status "open” or "closed” to the control center.
  • the electrical door openers known for this purpose are released or locked by applying a DC or AC voltage. For this purpose, they are connected to the control center via supply lines. Such door openers have proven themselves very well in practice.
  • the invention is based on the object of specifying an access control device of the type mentioned at the outset, which is protected against manipulation of the supply lines which is manipulated with the intention of sabotage.
  • control center has a transmitter for transmitting coded door opener control signals ("release door opener” or “lock door opener”), which are transmitted via the signal line to the door opener, in that the control center also interacts with a delay arrangement Includes evaluation unit, which is connected on the input side to the signal line for receiving the status signal, and which after the transmission of a "door opener release” signal, at least after a predetermined time has elapsed, the transmission of a "door opener lock” signal causes the swing latch Bolt is bistable and can be controlled to assume its two states, and that a decoder connected to the signal line is present on the door opener side, via the output signal of which the bistable bolt is controlled.
  • the invention has the advantage that the door opener is controlled via encrypted signals, so that it is impossible to unlock the door opener by applying the supply voltage. It is therefore unnecessary to protect the supply line mechanically. This also applies to the signal lines, because if the control code is not known, the door release cannot be activated, even if the signal line is directly accessible.
  • Another advantage is that no additional lines are required since the conventional signal line used for status reporting is used bidirectionally. Existing systems can therefore be easily upgraded. On the other hand, several door openers can alternatively be placed in parallel on one cable run.
  • a preferred development of the invention consists in that the "lock release" signal is transmitted via the evaluation unit as soon as the status signal "door or lock has been actuated” has been received via the signal line. This prevents secured access from being used by an unauthorized person if he succeeds an authorized person at short intervals.
  • each door opener has a mechanical coding switch (DIL switch) which is set during the door opener installation.
  • DIL switch mechanical coding switch
  • the single figure shows schematically a block diagram of an access control device.
  • an access control device comprises a control center 10 which controls and monitors a plurality of electric door openers. To keep the figure clear, only a single door opener 11 is shown.
  • the control center 10 and the door opener 11 are connected via a power supply line 12, a bidirectional signal line 13 and a potential equalization line 14.
  • the door opener 11 has a swivel latch (not shown) which can be locked or released via a bistable latch 15.
  • the bolt 15 is a two-armed Rocker arm formed, and is actuated via an arrangement of two electromagnets 16, 17.
  • the relevant magnet 16 or 17 is acted upon by a current pulse, so that the bolt assumes the other position in which it is detachably held by a leaf spring 18.
  • a status indicator 19 on the door opener side which monitors the open or closed position of the door (not shown) connected to the door opener 11.
  • actuation of the swivel trap can be detected with the status indicator 19.
  • the status indicator 19 When the door has been opened or the swivel latch has been deflected during an opening process, the status indicator 19 generates a signal which is transmitted to the control center 10 via the signal line 13.
  • the control center 10 comprises a computer with an evaluation unit 20, for example a microprocessor, which sends binary-coded control signals via the signal line 13 to the door opener 11 via a transmitter 21.
  • the evaluation unit 20 receives the status signal in the opposite direction.
  • the control signals are decrypted on the door opener side by a decoder 22.
  • the decoder 22 controls a switch 23, and this switches the supply voltage to one of the magnets 16 or 25 via a line 24 or 25 17, so that it is briefly energized and the bolt 15 is actuated.
  • the control signals contain a selection code which is exclusively assigned to the relevant door opener 11 and is fixed there. This can be irreversible through a Fixed wiring can be stamped or optionally changed. Each door opener can thus be selected individually and encrypted. If there is no match, actuation of the door opener 11 is excluded.
  • the decoder 22 is connected to a coding switch 26 (mini-DIL switch), on which the code relevant for the door opener 11 is set.
  • the door opener is actuated or the magnets 16, 17 are energized only when a correspondingly coded control signal is transmitted via the signal line 13.
  • the code coordination between the control center 10 and the door opener 11 takes place in principle when the door opener 11 is installed. However, if it is necessary, an adjustment or change can also be made at a later time.
  • the function of the access control device is explained below using an example. As an initial situation, it is assumed that the door opener 11 is locked. If access authorization has been verified by a user, the control center 10 transmits the control signal “release door release” together with the door release code. This causes a brief (approx. 100 ms) voltage to be applied to the magnet 16 and the latch 15 to be switched.
  • the status indicator 19 is then monitored by the evaluation unit 20 to determine whether the door has been opened or not. If there is no door opening during this time, the control center 10 transmits the coded control signal “lock door opener”, which causes a brief excitation of the magnet 17 and a switching of the bolt 15 into the “closed position”.
