Abstract

The present invention relates to an entrance barrier comprising a barrier element movable between an open and a closed position, driving means, by which the barrier element can driven from one position to the other position respectively, a control unit, by which the driving means are controllable, and a sensor unit connected to the control unit. The invention also relates to a barrier element for the entrance barrier and to method for operating the entrance barrier. To provide a possibility of further improving the safety of persons in the area of entrance barriers beyond the mere passive safety of the entrance barrier, the invention proposes for the sensor unit to include a capacitive sensor.

Claims

1. An entrance barrier (10) comprising a barrier element (12, 14) movable between an open and a closed position, driving means (16, 18), by which the barrier element (12, 14) can be driven from one position to the other respectively, a control unit (20), by which the driving means (16, 18) are controllable, and a sensor unit (36) connected to the control unit (20), and the sensor unit (36) being a capacitive sensor (22, 24).

2. The entrance barrier according to claim 1, wherein the sensor (22, 24) is arranged on the barrier element (12, 14).

3. The entrance barrier according to claim 1, wherein the sensor (22, 24) is formed at least partly by an electrically conducting part.

4. The entrance barrier according to claim 1, wherein the sensor (22, 24) includes especially an open conductor loop (26, 28, 30, 32) and/or a conductor surface.

5. The entrance barrier according to one of claim 1, wherein at least two, especially jointly movable barrier elements (12, 14).

6. The barrier element (12, 14) of the entrance barrier (10) according to claim 1.

7. The barrier element according to claim 6, wherein the sensor (22, 24) is formed as one piece with the barrier element (12, 14).

8. The barrier element according to claim 6, wherein the barrier element (12, 14) is formed in a two-part or multi-part design.

9. The method for operating an entrance barrier (10), wherein a barrier element (12,14) is moved by driving means (16, 18) between an open position and a closed position, the driving means (16, 18) being controlled by a control unit (20), wherein the presence particularly of a dielectrically permeable and/or electrically conducting body in a space (34) in the range of the barrier element (12, 14) is detected by means of a capacitive sensor (22, 24) and transmitted to the control unit (20).

10. The method according to claim 9, wherein the driving means (16, 18) are deactivated by the control unit (20).

11. The method according to claim 9, wherein an authorization for passage is verified.

12. The method according to claim 9, wherein the passage of the dielectrically permeable body is traced and/or recorded.

13. The method according to claim 9 to 12, characterized in that wherein a position of the barrier element (12, 14) is monitored by means of the sensor (22, 24).

14. The method according to claim 9, wherein several sensors (22, 24), especially sensors of adjacent entrance barriers are used, which are evaluated in a time-multiplex mode.

15. The method according to one of the claims claim 9, characterized in that wherein sensor (22, 24) is synchronized especially automatically.
