Abstract

A system and method is provided for remotely and automatically calibrating a mass-flow sensor in a yield monitor of a combine. The invention uses a wireless communication device installed on a combine and a remote wireless communication device installed on a grain carrier or truck carrier. Once an actual weight is obtained, calibration information is sent to the combine to calibrate the mass-flow sensor.

Claims

1-7. -7. (canceled)

8. A system for calibrating a mass-flow sensor on a yield monitor of a combine, comprising the steps of:

a first wireless transceiver operatively connected to the yield monitor; and

a second wireless transceiver operatively connected to a grain carrier for transmitting calibration information to the first wireless transceiver.

9. The system of claim 8, wherein grain harvested by the combine is transferred to the grain carrier.

10. The system of claim 9, wherein the calibration information includes information relating to the weight of the grain in the grain carrier.

11. The system of claim 8, wherein the calibration information is transmitted to the first wireless transceiver automatically.

12-21. -21. (canceled)

22. A system for calibrating the mass flow sensor on a combine comprising:

a yield monitor having a mass flow sensor on the combine;

a wireless communication device on the combine and in communication with the yield monitor that calibrates the mass flow sensor; and

a wireless communication device in communication with the wireless communication device on the combine, the communication device adapted to transmit information relating to the actual weight of the harvested grain.

24. The system of claim 22 wherein the communication device is a remote wireless communication device is on a grain carrier.

25. The system of claim 22 wherein the communication device is a remote wireless communication device is on a truck.

23. (canceled)
