Abstract

In one aspect, a system for detecting tripping of ground engaging tools on an agricultural implement may include a ground engaging tool coupled to an implement frame. Furthermore, the system may include a motion sensor installed on the implement frame, with the motion sensor configured to capture data indicative of motion of the implement frame. Moreover, the system may include a controller configured to monitor the motion of the implement frame based on the data received from the motion sensor. In addition, the controller may be further configured to determine when the ground engaging tool has tripped based on the monitored motion.

First claim

The invention claimed is:

1. A system for detecting tripping of ground engaging tools on an agricultural implement, the system comprising:
an implement frame;
a ground engaging tool coupled to the implement frame;
a biasing element coupled between the implement frame and the ground engaging tool, the biasing element being configured to bias the ground engaging tool to a predetermined ground engaging tool position relative to the implement frame;
a motion sensor installed on the implement frame, the motion sensor configured to capture data indicative of motion of the implement frame; and
a controller communicatively coupled to the motion sensor, the controller configured to monitor the motion of the implement frame based on the data received from the motion sensor, the controller further configured to determine when the ground engaging tool has tripped based on the monitored motion.

2. The system of claim 1 , wherein the controller is further configured to compare the monitored motion to a predetermined motion value and determine that the ground engaging tool has tripped when the monitored motion has exceeded the predetermined motion value.

3. The system of claim 2 , wherein the predetermined motion value corresponds to a first predetermined motion value, the controller further configured to:
compare the monitored motion to a second predetermined motion value, the second motion value being greater than the first motion value;
determine that the ground engaging tool has tripped when the monitored motion exceeds the first predetermined motion value and falls below the second predetermined motion value; and
determine that the ground engaging tool has become damaged when the monitored motion has exceeded the second predetermined motion value.

4. The system of claim 1 , wherein the controller is further configured to provide a notification to an operator of the agricultural implement when it is determined that the ground engaging tool has tripped.

5. The system of claim 1 , wherein the controller is further configured to initiate an adjustment of a ground speed of the agricultural implement when it is determined that the ground engaging tool has tripped.

6. The system of claim 1 , wherein the controller is further configured to generate a field map illustrating one or more locations of the agricultural implement within the field when it was determined that the ground engaging tool tripped.

7. The system of claim 1 , wherein the motion sensor comprises an inertial measurement unit.

8. The system of claim 1 , wherein the ground engaging tool comprises a shank.

9. An agricultural implement, comprising:
a frame;
a plurality of ground engaging tools, each ground engaging tool being independently coupled to the frame;
a plurality of biasing elements, each biasing element coupled between the frame and one of the plurality of ground engaging tools, each biasing element being configured to bias the corresponding ground engaging tool to a predetermined ground engaging tool position relative to the frame;
a motion sensor installed on the frame, the motion sensor configured to capture data indicative of motion of the frame; and
a controller communicatively coupled to the motion sensor, the controller configured to:
monitor the motion of the frame based on the data received from the motion sensor;
determine when a first ground engaging tool of the plurality of ground engaging tools has tripped or become damaged based on the monitored motion; and
determine which ground engaging tool of the plurality of ground engaging tools corresponds to the first ground engaging tool based on the monitored motion.

10. The agricultural implement of claim 9 , wherein the controller is further configured to:
determine an angular rate of change of an orientation of the frame based on the monitored motion; and
determine which ground engaging tool of the plurality of ground engaging tools corresponds to the first ground engaging tool based on the determined angular rate of change.

11. The agricultural implement of claim 9 , wherein the frame comprises a first section and a second section and the motion sensor comprises a first motion sensor installed on the first section of the frame and further comprising a second motion sensor installed on the second section of the frame.

12. The agricultural implement of claim 9 , wherein the controller is further configured to compare the monitored motion to a predetermined motion value and determine that the first ground engaging tool has tripped or become damaged when the monitored motion has exceeded the predetermined motion value.

13. The agricultural implement of claim 9 , wherein the controller is further configured to:
compare the monitored motion to first and second predetermined motion values, the second motion value being greater than the first motion value;
determine that the first ground engaging tool has tripped when the monitored motion exceeds the first predetermined motion value and falls below the second predetermined motion value; and
determine that the first ground engaging tool has become damaged when the monitored motion has exceeded the second predetermined motion value.

14. The agricultural implement of claim 9 , wherein the controller is further configured to initiate an adjustment of a ground speed of the agricultural implement when it is determined that the ground engaging tool has tripped or become damaged.

15. A method for detecting tripping of ground engaging tools on an agricultural implement, the agricultural implement comprising a frame and a ground engaging tool coupled to the frame, the method comprising:
receiving, with one or more computing devices, data indicative of motion of the frame;
determining, with the one or more computing devices, when the ground engaging tool has tripped based on the received data; and
providing, with the one or more computing devices, a notification to an operator of the agricultural implement when it is determined that the ground engaging tool has tripped.

16. The method of claim 15 , wherein determining when the ground engaging tool has tripped further comprises:
comparing, with the one or more computing devices, the monitored motion to a predetermined motion value; and
determining, with the one or more computing devices, that the ground engaging tool has tripped when the monitored motion has exceeded the predetermined motion value.

17. The method of claim 16 , wherein the predetermined motion value corresponds to a first predetermined motion value and determining when the ground engaging tool has tripped further comprises:
comparing, with the one or more computing devices, the monitored motion to a second predetermined motion value, the second motion value being greater than the first motion value;
determining, with the one or more computing devices, that the ground engaging tool has tripped when the monitored motion exceeds the first predetermined motion value and falls below the second predetermined motion value; and
determining, with the one or more computing devices, that the ground engaging tool has become damaged when the monitored motion has exceeded the second predetermined motion value.

18. The method of claim 15 , further comprising:
initiating, with the one or more computing devices, an adjustment of a ground speed of the agricultural implement when it is determined that the ground engaging tool has tripped.

19. The method of claim 15 , further comprising:
generating, with the one or more computing devices, a field map il
