| 摘要 |
The invention relates to a method in which in and out passage to or from a certain room or area, preferably a building or an enclosure, is controlled via an automatic door system, in which automatic door system a locking system (1) is provided, which comprises at least three main components including at least an operating panel (2), a control unit (3) and a motor-lock (4). The method is characterized in that a random code (H1, H2, H3) is transmitted from one main component (2, 3, 4) to another after a user has entered an authorization code (B1) via a registration device (16), which code is converted in an activation circuit card (23) to a first random code (H1), which varies randomly between each such main component (2, 3, 4) and in addition each time an authorization code (B1, B2) etc. is entered, which random code (H1) is received and verified by the control unit (3), following which another random code (H2) is transmitted to the motor-lock (4), which transmits its current status back to the control unit (3), following which a third random code (H3) is transmitted to the motor-lock (4) for opening its latch bolt (14) by means of an electric motor (47).
