Abstract

The present invention relates to a control system for a door drive with a plurality of components and a digital data bus via which the components communicate, wherein at least one safety component such as a closing edge-safety device or a light barrier detects safety-relevant events and reports the same via the data bus. When detecting a safety-relevant event, the safety component blocks the communication via the data bus for a certain time, wherein the remaining components detect the missing communication on the data bus and interpret the same as notification of a safety-relevant event.

Claims

1. A control system for a door drive with a plurality of components and a digital data bus via which the components communicate, wherein at least one safety component such as a closing-edge safety device or a light barrier detects safety-relevant events and reports the same via the data bus,

when detecting a safety-relevant event, the safety component blocks the communication on the data bus for a certain time, and the remaining components detect the missing communication on the bus system and interpret the same as notification of a safety-relevant event.

2. The control system according to claim 1, wherein the motor of the door drive is stopped and/or returned upon notification of a safety-relevant event.

3. The control system according to claim 1, wherein the communication via the data bus is controlled by a master component which individually addresses each of the slave components, and the safety component is a slave component.

4. The control system according to claim 3, wherein, when the communication on the data bus is enabled again, the master component asks the slave components which safety-relevant event has been detected and possibly outputs corresponding control commands.

5. The control system according to claim 1, wherein the communication via the data bus is controlled by a master component which individually addresses each of the slave components, and the safety component is the master component.

14. A door drive with a control system according to claim 1.

15. The control system according to claim 2, wherein the communication via the data bus is controlled by a master component which individually addresses each of the slave components, and the safety component is a slave component.

16. The control system according to claim 15, wherein, when the communication on the data bus is enabled again, the master component asks the slave components which safety-relevant event has been detected and possibly outputs corresponding control commands.

17. The control system according to claim 2, wherein the communication via the data bus is controlled by a master component which individually addresses each of the slave components, and the safety component is the master component.

6. The control system for a door drive with a plurality of components and a digital data bus via which the components communicate, wherein at least one safety component such as a closing-edge safety device or a light barrier detects safety-relevant events and reports the same via the data bus,

the communication via the bus system is controlled by an arbitration and, when detecting a safety-relevant event, the safety component transmits the notification of the event by using a system-specific address.

7. A door drive with a control system according to claim 6.

8. A method for controlling a door drive, in which a plurality of components communicate via a digital data bus, wherein at least one safety component such as a closing-edge safety device or a light barrier detects safety-relevant events and reports the same via the data bus,

when detecting a safety-relevant event, the safety component blocks the communication on the data bus for a certain time, and the remaining components detect the missing communication on the bus system and interpret the same as notification of a safety-relevant event.

9. The method according to claim 8, wherein the motor of the door drive is stopped and/or returned upon notification of a safety-relevant event.

10. The method according to claim 8, wherein the communication via the data bus is controlled by a master component which individually addresses each of the slave components, wherein the safety component is a slave component.

11. The method according to claim 10, wherein the master component, when the communication on the data bus is enabled again, asks the slave components which safety-relevant event has been detected and possibly outputs corresponding control commands.

12. The method according to claim 8, wherein the communication via the data bus is controlled by a master component, which individually addresses each of the slave components, wherein the safety component is the master component.

18. The method according to claim 9, wherein the communication via the data bus is controlled by a master component which individually addresses each of the slave components, wherein the safety component is a slave component.

19. The method according to claim 18, wherein the master component, when the communication on the data bus is enabled again, asks the slave components which safety-relevant event has been detected and possibly outputs corresponding control commands.

20. The method according to claim 9, wherein the communication via the data bus is controlled by a master component, which individually addresses each of the slave components, wherein the safety component is the master component.

13. The method for controlling a door drive, in which a plurality of components communicate via a digital data bus, wherein at least one safety component such as a closing-edge safety device or a light barrier detects safety-relevant events and reports the same via the data bus, the communication via the bus system is controlled by an arbitration and, when detecting a safety-relevant event, the safety component transmits the notification of the event by using a system-specific address.
