Abstract

The present invention relates to communication with remote crop characteristic sensors and verification of data transmitted therefrom. Embodiments of the present invention comprise systems, methods and apparatus for transmitting calibration data directly to a remote crop characteristic sensor and calibrating the remote sensor such that its measurements reflect accurate crop characteristics. Also comprised in embodiments of the present invention are systems, methods and apparatus for verifying remote crop sensor output. Some of these methods comprise transmitting from remote sensors crop characteristic data combined with calibration data identification so that a party can verify that the correct calibration data was used by the sensor while making the crop characteristic measurements.

Claims

1. A method for calibrating a crop characteristic sensor and verifying crop characteristic data comprising:

generating sensor calibration data for at least one crop variety;

transmitting said calibration data to one or more remote crop characteristic sensors;

calibrating said remote sensors with said calibration data;

measuring crop characteristic data with said calibrated sensors;

transmitting said crop characteristic data to a crop distributor;

transmitting an identifier of said calibration data used while measuring said crop characteristic data;

transmitting from said laboratory to said distributor an identifier of said crop calibration data transmitted to said remote sensors; and

verifying that said sensor calibration data transmitted to said remote sensors from said laboratory is functionally identical to said sensor calibration data used while measuring said crop characteristic data.

2. The method according to claim 1, wherein said transmitting said calibration data to remote crop characteristic sensors is performed using wireless data transmission.

3. The method according to claim 1, wherein said calibration data may vary according to time.

4. The method according to claim 1, wherein said calibration data is transmitted from a site remote from said remote sensors.

5. The method according to claim 1, wherein said calibration data is generated from crop samples provided to a laboratory, said samples representing variations of at least one crop characteristic.

6. The method according to claim 1, wherein said remote sensors are tamper-proof such that their calibration parameters may only be manipulated by select parties.

7. The method according to claim 1, further comprising transmitting from said remote sensors crop characteristic data and calibration identification data which identifies said sensor calibration data.

8. The method according to claim 1, further comprising transmitting tagged data to a verification service wherein said verification service, also receives independent calibration data and verifies that the crop characteristic data comprised in said tagged data was measured using correct calibration parameters.

9. A system for transmitting verified crop characteristic data comprising:

means for providing crop samples to a laboratory, said samples representing variations of at least one crop characteristic;

means for generating sensor calibration data based on said samples;

means for transmitting said calibration data to remote crop characteristic sensors;

means for calibrating said remote sensors with said calibration data;

means for measuring crop characteristic data with said calibrated sensors;

means for transmitting said crop characteristic data to a crop distributor;

means for transmitting, along with said crop characteristic data, an identifier of said calibration data used while measuring said crop characteristic data;

means for transmitting from said laboratory to said distributor an identifier of said crop calibration data transmitted to said remote sensors; and

means for verifying that said sensor calibration data transmitted to said remote sensors from said laboratory is functionally identical to said sensor calibration data used while measuring said crop characteristic data.
