Abstract

The invention relates to an access control device (1) having at least one access barrier element, to which at least one read unit and/or sensor unit for acquiring legitimation and/or security features is assigned, the access barrier elements and the read and sensor units each having a data connection to a computer unit (5), which compares the acquired or read features to stored data and opens or keeps closed the access barrier according to a preset. Proceeding from the problem that in the case of access control devices (1) of this type, it is only possible to react to changed requirements or a changed security condition by cumbersome re-parameterization of the facility, an additional operating element (8), which is assigned to the computer unit (5), is proposed in the context of the invention, using which it is possible to select between various security steps by simply adjusting the operating element (8).

Claims

1. An access control device having at least one access control element deblocking or blocking the access to a secured zone, a building, or an area, in particular having a rotating barrier, a turnstile, a revolving door, a camera, or a stop barrier (14), and at least one read unit to check at least one legitimation feature documenting an access authorization, and/or at least one sensor, in particular a light barrier, to check at least one security feature, such as the number of passing persons, the access barrier elements and the read unit and/or the sensors each being at least indirectly connected to at least one computer unit (5) of the access control device (1), this computer unit (5) having a storage element (7), in which permissible legitimation features, security features, or target values are stored, and a comparison of the read legitimation features to the stored legitimation features and/or a check of the security features detected by sensors to the permissible security features being performed using the processor unit and the access barrier element being releasable, preferably automatically, as a function of the result of this comparison, wherein

the central computer unit (5) of the access control device (1) is additionally provided with an operating element (8) for setting predefined security steps and a defined parameterization of the computer unit (5) is assigned to each of these security steps in such a manner that, as a function of the respectively set security step, the number of checked security and/or legitimation features and their particular tolerance threshold are uniquely predefined by selection of the security step using the operating element (8).

2. The access control device according to claim 1, wherein the operating element (8) is a graduated or continuously adjustable rotary switch.

3. The access control device according to claim 1, wherein parameterization software (16) is assigned to the operating unit (8) in such a manner that the security steps selectable using the operating unit (8) are each assigned a defined number of the security and/or legitimation features to be checked in a settable and/or changeable manner using the parameterization software (16).

4. The access control device according to claim 1, wherein the sensors combine to form a sensor network and individual sensors of this sensor network can be connected or disconnected using the operating unit.

5. The access control device according to claim 4, wherein at least a part of the sensors are optical sensors (23), in particular light barriers, whose optical axes are situated transversely to the passage direction through the access control device in the longitudinal direction and intersect one another diagonally while forming rhombuses, their number being increased and decreased as a result of connecting and disconnecting rhombus fields.

6. The access control device according to claim 1, wherein as a legitimation feature at least one biometric feature is checkable using the sensors, the degree of the correspondence to be required of the biometric feature acquired using a read unit being settable as a function of the selected security step in each case using the operating unit (8).

7. The access control device according to claim 1, wherein the computer unit (5) is incorporated in a data network (15), preferably an intranet, a WLAN network, and/or in the Internet, and the operating unit (8) and/or the parameterization software (16) is thus operable by remote control.
