Abstract

A signal unit is provided for signaling at least one operating state of a technical device such as a machine, installation, vehicle, or the like, having at least one acoustic signal transmitter ( 2 ) for generating an acoustic signal, thereby improving the monitoring of the technical device. This is achieved according to the invention by providing a sensor unit or detecting an acknowledgment of the signal.

Claims (22)

1. A signal unit for signaling at least one operating state of a machine, having at least one acoustic signal transmitter for generating an acoustic signal wherein the improvement comprises a dual function sensor unit having an acoustic signal transmitter for generating said acoustic signal and a sensing unit for detecting the acknowledgement of said acoustic signal.

2. The signal unit according to claim 1 further comprising at least one input element for inputting the acknowledgment by an operator.

3. The signal unit according to claim 1 wherein the sensor unit detects a first parameter of the acoustic signal.

4. The signal unit according to claim 1 or 3 wherein said parameter of the acoustic signal is at least the amplitude or the frequency of the signal.

5. The signal unit according to claim 1 wherein the sensor unit has a control unit for comparing the target-actual values of a parameter of the acoustic signal, whereby the acknowledgment generates the actual value.

6. The signal unit according to claim 3 wherein the control unit modifies a second parameter of the acoustic signal.

7. The signal unit according to claim 6 wherein the second parameter to be modified is at least the volume or the presence of the signal.

8. The signal unit according to claim 1 wherein the acoustic signal transmitter signals the acknowledged operating state.

9. The signal unit according to claim 1 further comprising at least one optical signal transmitter having a light-emitting diode for generating an optical signal.

10. The signal unit according to claim 9 wherein the control unit modifies a parameter of a light-emitting diode.

11. The signal unit according to claim 9 wherein the optical signal transmitter signals the acknowledged operating state.

12. The signal unit according to claim 1 wherein the acoustic signal transmitter includes at least one piezoelectric element.

13. The signal unit according to claim 1 wherein the sensor unit detects a contact or deformation of the acoustic signal transmitter.

14. The signal unit according to claim 1 wherein the sensor unit detects the amplitude or frequency of the acoustic signal transmitter as a result of a contact or deformation.

15. The signal unit according to claim 1 wherein the acoustic signal transmitter is a sensor in the sensor unit to achieve the sensor function and the signal function.

16. The signal unit according to claim 1 wherein the signal unit is a signal column.

17. The signal unit according to claim 16 wherein the signal column has an acoustic module for the acoustic signal transmitter or 6 has at least one light module for an optical signal transmitter.

18. The signal unit according to claim 1 further comprising one transmitting unit with a transmitter for wireless data transmission to a receiver.

19. A signaling device for signaling the operating state of a machine comprising:

(a) a piezoelectric element having a dual function of transmitting an acoustic signal and as a sensor for acknowledging the receipt of said acoustic signal; and

(b) a translucent housing having one or more light emitting diodes.

20. A signaling device for signalling signaling the operating state of a machine having an acoustic signal transmitter for generating an acoustic signal and a sensor for providing acknowledgment for receipt of said acoustic signal wherein the improvement comprises a dual function acoustic signal transmitter for generating said acoustic signal and a sensing unit for detecting the acknowledgment of said acoustic signal and a translucent housing having one or more light emitting diodes.
