Abstract

An automation system including a control device for controlling a processing device having at least one sensor for transmitting sensor data from the processing device to the control device. The sensor comprises a radio transmission device for providing wireless transmission of the sensor data from the transmission device to a radio reception device connected to or located in the control device.

Claims

1. An automation system including a control device for controlling a processing device and at least one sensor arrangement for transmitting sensor data provided by a sensor from the processing device to the control device, wherein the sensor arrangement contains a radio transmitter for providing wireless transmission of the sensor data to a radio receiver interconnected with the control device.

2. The automation system according to

claim 1

, wherein the radio transmitter of the processing device and the radio receiver of the control device are each a radio transceiver, and the radio transceiver of the control device transmits sensor control data to the radio transceiver of the processing device.

3. The automation system according to

claim 1

, wherein the radio receiver receives sensor data from a plurality of sensors.

4. The automation system according to

claim 1

, wherein the radio receiver is associated with a radio module that receives sensor data from a plurality of sensors and is connected directly to the control device.

5. The automation system according to

claim 1

, wherein the radio receiver is associated with a radio module that receives sensor data from a plurality of sensors and is connected to the control device.

6. The automation system according to

claim 5

, wherein the radio receiver is connected to the control device via a data bus.

7. The automation system according to

claim 6

, wherein a central data bus radio module is connected between the radio module and the data bus.

8. The automation system according to

claim 1

, wherein a data protocol for the data transmitted from the radio transmitter to the radio receiver provides a first data area associated with sensor identification data and a second data area associated with the transmitted sensor data.

9. The automation system according to

claim 2

, wherein a data protocol for the control data transmitted from the radio transceiver of the control device to the radio transceiver of the processing device provides a first data area associated with sensor identification data and a second data area associated with the control data.

10. The automation system according to

claim 1

, wherein the sensor data consists of binary signals.

11. The automation system according to

claim 9

, wherein the control data consists of binary signals.

12. The automation system according to

claim 2

, wherein energy providing the sensor with an operating current is transferred by electromagnetic emission from the control device to the sensor via the radio transceiver of the processing device.

13. An automation system comprising:

a control device;

a processing device controlled by the control device; and

a sensor arrangement comprising a sensor that obtains sensor data from the processing device;

wherein the sensor arrangement wirelessly transmits the sensor data from the processing device to the control device.

14. The automation system according to

claim 13

, wherein the processing device has a plurality of sensor arrangements.

15. The automation system according to

claim 14

, further comprising a data bus connecting the plurality of sensor arrangements with the control device.

16. The automation system according to

claim 15
