ACCESS CONTROL SYSTEM COMPRISING A SLIDING DOOR AND VISUALIZATION OF STATUS INFORMATION

摘要

The invention relates to a system for controlling an access to an access-restricted zone (22) in a building, comprising a sliding door system (5) and a control device (8, 10) for the sliding door system (5). The sliding door system (5) has a door frame (2) and a sliding door (4) which can be displaced in the door frame (2) between a closed position and an open position by means of a drive unit (6). The door frame (2) has a pass-through region (24) and a wall panelling region (18) which at least partially receives the sliding door (4) in the open position. A control device (8) is arranged at the sliding door (4) and is communicatively connected to the drive device (6). The control device (8) is designed to control a displacement of the sliding door (4) between the closed position and an open position. A light projection device (13) is arranged in an interior space of the sliding door (4) and is communicatively connected to the control device (8). The light projection device (13) is designed to project status information (23), which is predetermined by the control device (8), for a user (20) requesting access to an access-restricted zone (22) as a visible light projection onto a projection surface (27, 27a).
