Abstract

A measuring device and method for process automation in an industrial environment. The measuring device includes a radio module having a first radio channel that transmits measurement data, a second radio channel that transmits the measurement data, and control circuitry that controls the first radio channel and the second radio channel in such a way that identical measurement data is transmitted by the two radio channels.

First claim

The invention claimed is:

1. A level measuring device, flow measuring device, pressure measuring device or limit level measuring device, configured for process automation in an industrial environment, comprising:
a radio module, the radio module including:
a first radio channel, configured to transmit measurement data, and
a second radio channel, configured to transmit the measurement data; and

control circuitry configured to control the first radio channel and the second radio channel in such a way that identical measurement data are transmitted by both the first and the second radio channel,
wherein the first radio channel is configured to transmit the measurement data via a different radio technology than the second radio channel.

2. The measuring device according to claim 1 ,
wherein the control circuitry is configured to always instruct the first radio channel and the second radio channel to send the measurement data, independently of received data.

3. The measuring device according to claim 1 ,
wherein the first radio channel is an LPWAN radio channel, and
wherein the second radio channel is a mobile radio channel.

4. The measuring device according to claim 3 ,
wherein the LPWAN radio channel is a LoRa, Sigfox, NB-IoT or Mioty radio channel.

5. The measuring device according to claim 1 ,
where the first radio channel is a LoRa radio channel; and
where the second radio channel is an LPWAN radio channel that is not a LoRa radio channel.

6. The measuring device according to claim 3 ,
wherein the LPWAN radio channel is configured to transmit the measurement data at a radio frequency below 1 GHz or 1 MHz.

7. The measuring device according to claim 3 ,
wherein the LPWAN radio channel is configured to transmit the measurement data with a range of up to at least 50 km.

8. The measuring device according to claim 1 ,
wherein the measuring device is configured to transmit the measurement data immediately successively or simultaneously by way of the first radio channel and the second radio channel.

9. The measuring device according to claim 1 ,
wherein the radio module comprises a first radio including the first radio channel and a second radio including the second radio channel.

10. The measuring device according to claim 2 ,
where the first radio channel is a LoRa radio channel; and
where the second radio channel is an LPWAN radio channel that is not a LoRa radio channel.

11. The measuring device according to claim 4 ,
wherein the LPWAN radio channel is configured to transmit the measurement data at a radio frequency below 1 GHz or 1 MHz.

12. The measuring device according to claim 5 ,
wherein the LPWAN radio channel is configured to transmit the measurement data at a radio frequency below 1 GHz or 1 MHz.

13. A method of transmitting data from a level measuring device, a flow measuring device, a pressure measuring device or a limit level measuring device, to an external receiver, comprising:
transmitting measurement data through a first radio channel of a radio module via a first radio technology;
transmitting the measurement data by a second radio channel of the radio module via a second radio technology, which is different to the first radio technology; and
controlling the first radio channel and the second radio channel in such a way that identical measurement data are transmitted by the first and second radio channels.

14. A non-transitory computer readable medium having program element which, when executed on control circuitry of a level measuring device, a flow measuring device, a pressure measuring device or a limit level measuring device, instructs the level measuring device, the flow measuring device, the pressure measuring device or the limit level measuring device to perform a method comprising:
transmitting measurement data through a first radio channel of a radio module via a first radio technology;
transmitting the measurement data through a second radio channel of the radio module via a second radio technology, which is different to the first radio technology; and
controlling the first radio channel and the second radio channel in such a way that identical measurement data are transmitted by the first and second radio channels.
