Abstract

An agricultural machine includes a set of ground engaging elements that perform a ground engaging operation. The agricultural machine includes a rearward sensor mounted to the agricultural machine to sense an area of ground behind the agricultural machine and generate a rearward sensor signal. The agricultural machine includes rearward zone generator logic that determines a first zone and a second zone, wherein the first zone and the second zone represent portions of the area of ground behind the agricultural machine. The agricultural machine includes rearward residue generator logic configured to receive the rearward sensor signal and determine a first residue metric indicative of the amount of residue in the first zone. The agricultural machine includes control logic that controls one or more aspects of the ground engaging operation on the area of ground based on the first residue metric.

First claim

What is claimed is:

1 . An agricultural system for detecting error comprising:
an agricultural implement including a frame and a ground-engaging tool coupled to the frame, wherein the ground-engaging tool is configured to engage soil within a field as the agricultural implement is moved across the field; a forward sensor configured to capture data indicative of a pre-worked residue characteristic forward of the ground-engaging tool relative to a direction of travel of the agricultural implement; a rearward sensor configured to capture data indictive of a post-worked residue characteristic of a portion of the field rearward of the ground-engaging tool relative to a direction of travel of the agricultural implement; and a control system configured to:
determine a differential between the pre-worked residue characteristic and the post-worked residue characteristic for the portion of the field; and
identify when the agricultural implement is experiencing an error based at least in part on the differential between the pre-worked residue characteristic and the post-worked residue characteristic.

2 . The agricultural system of claim 1 , wherein the error comprises plugging of the ground-engaging tool.

3 . The agricultural system of claim 2 , wherein the control system is configured to identify that the ground-engaging tool is experiencing plugging based on the differential between the pre-worked residue characteristic and the post-worked residue characteristic and a threshold.

4 . The agricultural system of claim 1 , wherein the control system comprises a controller.

5 . The agricultural system of claim 1 , wherein the pre-worked residue characteristic comprises one of residue distribution, residue coverage, residue volume, or residue weight.

6 . The agricultural system of claim 1 , wherein the forward sensor comprises a first forward sensor, the rearward sensor comprises a first rearward sensor, the ground-engaging tool comprises a first ground-engaging tool, and the differential comprises a first differential, the agricultural system further comprising:
a second forward sensor configured to capture data indicative of a pre-worked residue characteristic forward of a second ground-engaging tool; and a second rearward sensor configured to capture data indicative of a post-worked residue characteristic of a portion of the field rearward of the second ground-engaging tool relative to the direction of travel of the agricultural implement; wherein the control system is further configured to identify that the second ground-engaging tool is experiencing plugging based at least in part on a second differential between the pre-worked residue characteristic forward of the second ground-engaging tool and the post-worked residue characteristic of the portion of the field rearward of the second ground-engaging tool.

7 . The agricultural system of claim 1 , wherein the forward sensor comprises a first forward sensor, the rearward sensor comprises a first rearward sensor, the ground-engaging tool comprises a first ground-engaging tool, and the differential comprises a first differential, the agricultural system further comprising:
a second forward sensor configured to capture data indicative of a pre-worked residue characteristic forward of a second ground-engaging tool; and a second rearward sensor configured to capture data indicative of a post-worked residue characteristic of a portion of the field rearward of the second ground-engaging tool relative to the direction of travel of the agricultural implement; wherein the control system is further configured to:
determine a second differential between the pre-worked residue characteristic forward of the second ground-engaging tool and the post-worked residue characteristic for the portion of the field rearward of the second ground-engaging tool; and
identify when the agricultural implement is experiencing the error based at least in part on the first differential and the second differential.

8 . The agricultural system of claim 7 , wherein the control system is further configured to configured to determine a difference between the first differential and the second differential and to identify when the agricultural implement is experiencing the error based at least in part on the difference between the first differential and the second differential and a threshold.

9 . The agricultural system of claim 1 , wherein the control system is further configured to initiate a control action when the control system identifies that the agricultural implement is experiencing the error, the control action comprises at least one of notifying an operator that the agricultural implement is experiencing the error, adjusting a position of the ground-engaging tool relative to the field, or adjusting a force applied to the ground-engaging tool.

10 . The agricultural system of claim 1 and further comprising:
a towing vehicle configured to move across the field, the agricultural implement coupled to the towing vehicle, wherein the forward sensor is supported on the towing vehicle.

11 . The agricultural system of claim 1 , wherein the forward sensor is supported relative to the frame at or adjacent to a forward end of the agricultural implement relative to the direction of travel and wherein the rearward sensor is supported relative to the frame at or adjacent to a rearward end of the agricultural implement relative to the direction of travel.

12 . The agricultural system of claim 1 , wherein the forward sensor or the rearward sensor comprises at least one of a camera, an optical sensor, a RADAR sensor, an ultrasonic sensor, or LIDAR sensor.

13 . The agricultural system of claim 1 , wherein the ground-engaging tool comprises at least one of a shank or a disc.

14 . An agricultural system comprising:
an agricultural implement including a frame and at least one ground-engaging tool coupled to the frame, the at least one ground-engaging tool configured to engage soil within a field as the agricultural implement is moved across the field; at least one rearward sensor configured to capture data indicative of a post-worked residue characteristic of a portion of the field rearward of the at least one ground-engaging tool relative to a direction of travel of the agricultural implement; and a control system configured to:
monitor data received from the at least one rearward sensor;
determine the post-worked residue characteristic for the portion of the field rearward of the at least one ground-engaging tool; and
identify when the at least one ground-engaging tool is experiencing an error based at least in part on the determined post-worked residue characteristic for the portion of the field rearward of the at least one ground-engaging tool, wherein the error comprises plugging of the at least one ground-engaging tool.

15 . The agricultural system of claim 14 and further comprising:
at least one forward sensor configured to capture data indicative of a pre-worked residue characteristic forward of the at least one ground-engaging tool relative to the direction of travel of the agricultural implement;
wherein the control system is further configured to:
monitor data received from the at least one forward sensor;
determine the pre-worked residue characteristic forward of the at least one ground-engaging tool; and
identify when the at least one ground-engaging tool is experiencing the error based at least in part on the determined post-worked residue characteristic for the portion of the field rearward of the at least one ground-engaging tool and the determined pre-wor
