Radar sensor with a communication interface

1. A radar measuring device for factory automation and/or logistics automation with:

a supply unit for supplying downstream units with energy,

a communication unit for receiving data from a superordinate unit and for a transfer of data from the radar measuring device to the superordinate unit, and

an evaluation and control unit for controlling a downstream high-frequency unit and for evaluating measurement data determined by the high-frequency unit,

wherein the communication unit is configured as a single-drop interface, wherein the supply unit is integrated into the communication unit, wherein the radar measuring device has an intermediate energy accumulator, which is connected to the integrated supply unit of the communication unit, and additionally to the evaluation and control unit, as well as the high frequency unit, wherein the intermediate energy accumulator is charged by the integrated supply unit of the communication unit, when the high-frequency unit is operated in energy saving mode.

2. The radar measuring device of claim 1 , wherein the single-drop interface is configured as an IO link interface.

3. The radar measuring device of claim 1 , wherein the high-frequency unit has a measuring frequency of 100 GHz-3,000 GHz.

4. The radar measuring device of claim 1 , wherein the radar measuring device has an input circuit to ensure electromagnetic compatibility.

5. The radar measuring device of claim 1 , wherein the evaluation and control unit has an energy management device.

6. The radar measuring device of claim 1 , wherein the supply unit is integrated into the communication unit.

7. The radar measuring device of claim 1 , wherein the radar measuring device has an intermediate energy accumulator.

8. A method for operating a radar measuring device with a supply unit for supplying downstream units with energy, a communication unit to receive data from a superordinate unit and for transmitting data of the radar measuring device to the superordinate unit, an evaluation and control unit to control a downstream high-frequency unit and to evaluate measurements determined by the high-frequency unit, with the communication unit being embodied as a single-drop interface, wherein the supply unit is integrated into the communication unit, wherein the radar measuring device has an intermediate energy accumulator, which is connected to the integrated supply unit of the communication unit, wherein the high-frequency unit is operated in an energy saving mode and activated at the request of a superordinate unit and/or cyclically for carrying out a measurement, and returned to the energy-saving mode after completing the measurement, and wherein the intermediate energy accumulator is charged by the integrated supply unit of the communication unit when the high-frequency unit is operated in energy saving mode.

9. The method of claim 8 , wherein the radar measuring device has an intermediate energy accumulator, and the high-frequency unit is supplied with energy at least partially from the intermediate energy accumulator.

10. The method of claim 8 , wherein the evaluation and control unit has an energy management device that activates and disables the high-frequency unit over the energy management device.

11. The method of using the radar measuring device in claim 8 in an IO link network.

12. The method of use of claim 11 , wherein the method is used in factory automation or logistics automation.
