Abstract

The HMI system is provided with a mobile control and monitoring device for automation components of a technical system. It comprises means for contactless data transmission between the mobile control and monitoring device and the automation components, a manual device for triggering or blocking security relevant operations of the technical system and means for locating the mobile control and monitoring device. Evaluation means are provided for managing an active operational area and which activate the automation components for security-relevant operations of the technical system via the mobile control and monitoring device solely when the manual device is released and the locating means detect that the mobile control and monitoring device is located inside the active operational area, the advantage thereof being that manual triggering of security-relevant operations by an operator is the condition upon which they can be activated via the mobile control and monitoring device. If the manual device is placed directly on the housing of the technical system, for example, an operator has to approach in such a way that he/she enters the active operation are in a secure manner.

Claims

1-8. -8. (canceled)

9. An HMI system, comprising:

at least one mobile control and monitoring device for controlling automation components of a technical facility;

a transmitting device for data transmission between the mobile control and monitoring device and the automation components, the data transmission not requiring physical contact between the mobile control and monitoring device and the automation components;

a safety device for manually releasing or blocking safety-relevant operations of the technical facility;

a locating device for locating the mobile control and monitoring device; and

an evaluation device for managing an active operating area, wherein the evaluation device is configured to activate the automation components for executing safety-relevant operations triggered by the mobile control and monitoring device only if

the safety device is in a release position, and

the locating device confirms a current location of the mobile control and monitoring device to be inside the active operating area.

10. The HMI system according to claim 9, wherein the evaluation device is further configured to manage a warning area located outside the active operating area and to output a warning message to the mobile control and monitoring device if the locating device detects a current location of the mobile control and monitoring device to be inside the warning area.

11. The HMI system according to claim 10, wherein the warning message is output only if the mobile control and monitoring device has been located within the active operating area before being detected within the warning area.

12. The HMI system according to claim 9, the evaluation device is further configured to suspend the automation components from executing safety-relevant operations triggered by the mobile control and monitoring device if

the safety device is in a release position, and

the locating device detects a current location of the mobile control and monitoring device to be outside the active operating area.

13. The HMI system according to claim 10, the evaluation device is further configured to suspend the automation components from executing safety-relevant operations triggered by the mobile control and monitoring device if the locating device detects a current location of the mobile control and monitoring device to be outside the warning area.

14. The HMI system according to claim 9, wherein the safety device is directly attached to a housing of the technical facility.

15. The HMI system according to claim 9, wherein the locating device is configured to determine a distance between the mobile control and monitoring device and the technical facility.

16. The HMI system according to claim 9, wherein the locating device is configured to detect a current position of the mobile control and monitoring device.
