Abstract

An agricultural implement system is provided that includes a row unit configured to deposit seeds within soil. The agricultural implement system also includes a bounce sensor rigidly coupled to the row unit and configured to output a signal indicative of a bounce magnitude, a bounce direction, or a combination thereof, of the row unit.

Claims

1. An agricultural implement system, comprising:

a plurality of row units each configured to deposit seeds within soil, wherein each row unit comprises a seed tube configured to direct seeds into the soil, a housing mounted to the seed tube, and a seed sensor disposed within the housing, and wherein the seed sensor is configured to monitor a flow of seeds through the seed tube; and

a bounce sensor rigidly coupled to at least one row unit, wherein the bounce sensor is disposed within the housing of the at least one row unit and configured to output a signal indicative of a bounce magnitude, a bounce direction, or a combination thereof, of the at least one row unit.

2. The agricultural implement system of claim 1, comprising an electronic control unit configured to receive data from a networked sensor interface, wherein the bounce sensor is configured to output the signal indicative of bounce to the networked sensor interface.

3. The agricultural implement system of claim 2, wherein the electronic control unit is configured to output a signal to a tow vehicle controller indicative of bounce.

4. The agricultural implement system of claim 1, wherein the bounce sensor comprises an accelerometer.

5. The agricultural implement system of claim 1, comprising a plurality of bounce sensors, wherein each bounce sensor is rigidly coupled to each row unit.

6. The agricultural implement system of claim 5, comprising an electronic control unit configured to receive data from each bounce sensor and compute an average bounce magnitude, an average bounce direction, or a combination thereof.

7. The agricultural implement system of claim 1, wherein the at least one row unit comprises circuitry disposed within the housing of the at least one row unit, the circuitry being communicatively coupled to the seed sensor and to the bounce sensor, and configured to process signals received from the seed sensor and from the bounce sensor.

8. An agricultural implement system, comprising:

a row unit having a seed sensor configured to monitor a flow of seeds and to output a first signal through a networked sensor interface indicative of the flow of seeds;

a bounce sensor configured to output a second signal through the networked sensor interface indicative of a bounce magnitude, a bounce direction, or a combination thereof, of the agricultural implement system;

an electronic control unit configured to receive the first signal and the second signal from the networked sensor interface and to determine the bounce magnitude, the bounce direction, or a combination thereof, based on the second signal; and

a housing mounted to a seed tube of the row unit, wherein the housing at least partially encloses the seed sensor and the bounce sensor.

9. The agricultural implement system of claim 8, wherein the bounce sensor is rigidly coupled to the row unit.

10. The agricultural implement system of claim 8, wherein the electronic control unit is configured to output a third signal to a tow vehicle controller indicative of the bounce magnitude, the bounce direction, or a combination thereof.

11. The agricultural implement system of claim 8, comprising a plurality of row units each having a seed sensor, wherein each seed sensor is configured to output the first signal through the networked sensor interface.

12. The agricultural implement system of claim 11, comprising a plurality of bounce sensors, wherein each bounce sensor is rigidly coupled to each row unit, and each bounce sensor is configured to output the second signal through the networked sensor interface.

13. The agricultural implement system of claim 11, comprising a bus configured to relay the first signal and the second signal from the networked sensor interface to the electronic control unit.

14. The agricultural implement system of claim 8, wherein the bounce sensor comprises an accelerometer.

15. The agricultural implement system of claim 8, wherein the housing at least partially encloses the networked sensor interface.

16. An agricultural implement system, comprising:

a plurality of row units each having a seed sensor configured to monitor a flow of seeds and to output a first signal through a networked sensor interface indicative of the flow of seeds;

a bounce sensor rigidly coupled to at least one row unit, wherein the bounce sensor is configured to output a second signal through the networked sensor interface indicative of a bounce magnitude, a bounce direction, or a combination thereof, of the at least one row unit;

an electronic control unit configured to receive the first signal and the second signal from the networked sensor interface and to determine the bounce magnitude, the bounce direction, or a combination thereof, based on the second signal; and

a plurality of housings each mounted to a respective seed tube of each row unit, wherein each housing at least partially encloses the seed sensor, and the housing of the at least one row unit at least partially encloses the bounce sensor.

17. The agricultural implement system of claim 16, comprising a plurality of bounce sensors each rigidly coupled to each row unit.

18. The agricultural implement system of claim 16, comprising a bus configured to relay the first signal and the second signal from the networked sensor interface to the electronic control unit.

19. The agricultural implement system of claim 16, wherein the electronic control unit is configured to output a third signal to a tow vehicle controller indicative of the bounce magnitude, the bounce direction, or a combination thereof.

20. The agricultural implement system of claim 16, wherein the housing of the at least one row unit at least partially encloses the networked sensor interface.
