Abstract

A planter monitor system and method that provides an operator with near real-time data concerning yield robbing events and the economic cost associated with such yield robbing events so as to motivate the operator to take prompt corrective action.

First claim

The invention claimed is:

1. A monitor system for an agricultural seed planter having a plurality of row units, each of the plurality of row units having a seed meter adapted to discharge seeds in a seed path as the planter moves through a field, the monitor system comprising:
a seed sensor associated with at least one of the row units and disposed with respect to the seed path to generate a discharged seed signal as each seed discharged by the seed meter passes said seed sensor;
a visual display; and
processing circuitry operably electrically coupled to said visual display and to said seed sensor, said processing circuitry configured to monitor and display information pertaining to operation of the planter (“Seed Planting Information”), wherein said Seed Planting Information indicates a planting consistency of a plurality of seeds, wherein said planting consistency is determined based on a variation in time intervals between said discharged seed signals.

2. The monitor system of claim 1 , wherein said Seed Planting Information indicates a yield-robbing event.

3. The monitor system of claim 2 , wherein said Seed Planting Information indicates a metering error.

4. The monitor system of claim 3 , wherein said Seed Planting Information includes one of a quantification of skips detected during a sampling period, a quantification of multiples detected during a sampling period, and quantification of seed singulation.

5. The monitor system of claim 4 , wherein said Seed Planting Information includes a plurality of initial seed placement calculations, wherein said initial seed placement calculations include skips and misplaced seeds.

6. The monitor system of claim 5 , wherein said processing circuitry distinguishes between skips and misplaced seeds by validating said initial seed placement calculations.

7. The monitor system of claim 6 , wherein said processing circuitry validates said initial seed placement calculations by comparing a first average value of a first set of previously recorded time intervals to a second average value of a second set of previously recorded time intervals.

8. The monitor system of claim 4 , further comprising:
an accelerometer associated with at least one of the row units, wherein said accelerometer is disposed to detect vertical acceleration of the row unit as the planter traverses the field.

9. The monitor system of claim 8 , wherein said processing circuitry is further configured to calculate and display a ride criterion.

10. The monitor system of claim 9 wherein said ride criterion is related to a percentage of a sampling period during which a kinematic criterion is outside a predefined range.

11. The monitor system of claim 4 , further comprising:
a load sensor associated with a depth regulation member of one of the row units and disposed to generate load signals corresponding to loads exerted on said depth regulation member, wherein said processing circuitry is further configured to monitor and display information pertaining to loads exerted on said depth regulation member (“Load Information”).

12. The monitor system of claim 11 wherein said Load Information includes a load parameter, wherein said load parameter is a function of a minimum load on the depth regulation member during a sampling period.

13. The monitor system of claim 3 , wherein said Seed Planting Information is calculated by comparing said time intervals between said discharged seed signal generated by said seed sensor to a threshold, wherein said threshold is calculated by multiplying a presumed time interval by a constant value, wherein said presumed time interval between said discharged seed signal is calculated based on a speed of said planter and a target population.

14. The monitor system of claim 2 , wherein said Seed Planting Information indicates a planting error.

15. The monitor system of claim 14 , wherein said Seed Planting Information comprises a spacing quality value.

16. The monitor system of claim 15 , wherein said spacing quality value is calculated by determining a ratio between a number of good spaced seeds and a number of misplaced seeds.

17. The monitor system of claim 1 , wherein said Seed Planting Information comprises a graphical representation of a plurality of seed placement locations in a row over a distance behind the planter.

18. The monitor system of claim 17 , wherein said graphical representation graphically indicates a seed placement classification.

19. The monitor system of claim 18 , wherein said seed placement classification comprises classification as a misplaced seed, a skip, or a double.

20. The monitor system of claim 18 , wherein said graphical representation comprises a scale indicating said distance behind the planter, and wherein said graphical representation comprises a plurality of seed placement icons disposed along said scale.

21. The monitor system of claim 20 , wherein said seed placement classification is indicated by a graphical icon disposed along said scale.

22. The monitor system of claim 21 , wherein said seed placement classification comprises classification as a misplaced seed, a skip, or a double.

23. The monitor system of claim 22 , wherein said graphical representation is color-coded.

24. The monitor system of claim 20 , wherein said seed placement classification is indicated by a graphical icon disposed along said scale.

25. A method of monitoring an agricultural seed planter having a plurality of row units, each of the plurality of row units having a seed meter adapted to discharge seeds in a seed path as the planter moves through a field, the method comprising:
generating a discharged seed signal as each seed discharged by the seed meter passes by a seed sensor disposed along the seed path; and
displaying information pertaining to operation of the planter (“Seed Planting Information”) to a user, wherein said Seed Planting Information indicates a planting consistency of a plurality of seeds, wherein said planting consistency is determined based on a variation in time intervals between said discharged seed signals.

26. The method of claim 25 , wherein said Seed Planting Information indicates a yield-robbing event.

27. The method of claim 26 , wherein said Seed Planting Information indicates a metering error.

28. The method of claim 27 , wherein said Seed Planting Information includes one of a quantification of skips detected during a sampling period, a quantification of multiples detected during a sampling period, and quantification of seed singulation.

29. The method of claim 28 , wherein said Seed Planting Information includes a plurality of initial seed placement calculations, wherein said initial seed placement calculations include skips and misplaced seeds.

30. The method of claim 29 , further comprising:
distinguishing between skips and misplaced seeds by validating said initial seed placement calculations.

31. The method of claim 30 , further comprising:
validating said initial seed placement calculations by comparing a first average value of a first set of previously recorded time intervals to a second average value of a second set of previously recorded time intervals.

32. The method of claim 28 , further comprising:
detecting vertical acceleration of at least one of the row units as the planter traverses th
