Abstract

A system for managing material accumulation relative to an agricultural implement may include a ground engaging tool supported on an agricultural implement and an infrared sensor having a field of view directed towards the ground engaging tool. The infrared sensor may be configured to generate data indicative of a temperature gradient of field materials at the ground engaging tool. A controller of the system may be communicatively coupled to the infrared sensor. The controller may monitor the data received from the infrared sensor and determine a presence of material accumulation relative to the ground engaging tool based at least in part on the temperature gradient of the field materials at the ground engaging tool.

First claim

What is claimed is:

1. A system for managing material accumulation relative to an agricultural implement, the system comprising:
a ground engaging tool supported on an agricultural implement;
an infrared sensor having a field of view directed towards the ground engaging tool, the infrared sensor being configured to generate data indicative of a temperature gradient of field materials at the ground engaging tool; and
a controller communicatively coupled to the infrared sensor, the controller being configured to monitor the data received from the infrared sensor and determine a presence of material accumulation relative to the ground engaging tool based at least in part on the temperature gradient of the field materials at the ground engaging tool.

2. The system of claim 1 , wherein the controller is configured to compare the temperature gradient to a predetermined gradient threshold and identify the presence of material accumulation relative to the ground engaging tool when the temperature gradient falls below the predetermined gradient threshold.

3. The system of claim 2 , wherein the controller is configured to determine the presence of material accumulation relative to the ground engaging tool when the temperature gradient of the field materials at the ground engaging tool falls below the predetermined gradient threshold for a given period of time.

4. The system of claim 2 , wherein the predetermined gradient threshold is selected based on at least one of a temperature of soil within the field or a temperature of residue within the field.

5. The system of claim 1 , wherein the ground engaging tool comprises a first ground engaging tool, the system further comprising a second ground engaging tool, wherein the controller is configured to compare the temperature gradient of the field materials at the first ground engaging tool to a temperature gradient of field materials at the second ground engaging tool.

6. The system of claim 5 , wherein the controller is configured to determine the presence of material accumulation relative to the first ground engaging tool when the temperature gradient of the field materials at the first ground engaging tool differs from the temperature gradient of field materials at the second ground engaging tool by a predetermined threshold differential.

7. The system of claim 1 , wherein the infrared sensor comprises an infrared camera.

8. The system of claim 1 , wherein the controller is further configured to initiate a control action based at least in part on the determination of the presence of material accumulation relative to the ground engaging tool.

9. The system of claim 8 , wherein the control action comprises controlling an operation of an actuator provided in operative association with the agricultural implement to adjust a penetration depth of the ground engaging tool.

10. The system of claim 8 , wherein the control action comprises notifying an operator of the agricultural implement of the material accumulation relative to the ground engaging tool.

11. A method for managing material accumulation relative to an agricultural implement as the agricultural implement performs an agricultural operation within a field, the method comprising:
receiving, with a computing device, data indicative of a temperature gradient of field materials at a ground engaging tool of the agricultural implement;
identifying, with the computing device, a presence of material accumulation relative to the ground engaging tool based at least in part on the temperature gradient of the field materials at the ground engaging tool; and
initiating, with the computing device, a control action associated with managing an amount of material accumulation relative to the ground engaging tool.

12. The method of claim 11 , further comprising comparing, with the computing device, the temperature gradient to a predetermined gradient threshold.

13. The method of claim 12 , wherein identifying the presence of material accumulation relative to the ground engaging tool comprises identifying the presence of material accumulation when the temperature gradient falls below the predetermined Gradient threshold.

14. The method of claim 12 , wherein the predetermined gradient threshold is selected based on at least one of a temperature of soil within the field or a temperature of residue within the field.

15. The method of claim 11 , wherein the ground engaging tool comprises a first ground engaging tool, the method further comprising receiving data indicative of a temperature gradient of field materials at a second ground engaging tool of the agricultural implement and comparing the temperature gradient of the field materials at the first ground engaging tool to the temperature gradient of field materials at the second ground engaging tool.

16. The method of claim 15 , wherein identifying the presence of material accumulation relative to the first ground engaging tool comprises identifying the presence of material accumulation when the temperature gradient of the field materials at the first ground engaging tool differs from the temperature gradient of field materials at the second ground engaging tool by a predetermined threshold differential.

17. The method of claim 11 , wherein the data indicative of the temperature gradient of field materials is received from an infrared sensor.

18. The method of claim 17 , wherein the infrared sensor comprises an infrared camera.

19. The method of claim 11 , wherein the control action comprises controlling an operation of an actuator to adjust a penetration depth of the ground engaging tool.

20. The method of claim 11 , wherein the control action comprises notifying an operator of the agricultural implement of the material accumulation relative to the ground engaging tool.
