Abstract

A system for monitoring basket plugging for agricultural implements includes a basket assembly configured to be supported by an agricultural implement and a range sensor positioned relative to the basket assembly such that the range sensor is configured to transmit detection signals towards an interior of the basket assembly and receive return signals based on reflection of the detection signals off at least one surface. The system also includes a controller communicatively coupled to the range sensor. The controller is configured to analyze data received from the range sensor as the basket assembly rotates relative to the range sensor to determine when the basket assembly is experiencing a plugged condition.

First claim

The invention claimed is:

1. A system for monitoring basket plugging for agricultural implements, the system comprising:
a basket assembly configured to be supported by an agricultural implement;
a range sensor positioned relative to the basket assembly such that the range sensor is configured to transmit detection signals towards an interior of the basket assembly and receive return signals based on reflection of the detection signals off at least one surface; and
a controller communicatively coupled to the range sensor, the controller configured to analyze data received from the range sensor as the basket assembly rotates relative to the range sensor to determine when the basket assembly is experiencing a plugged condition.

2. The system of claim 1 , wherein the controller is configured to calculate a detection range metric indicative of a percentage of the detection signals that reach at least one of a given location within the interior of the basket assembly or a range of locations defined relative to the given location within the interior of the basket assembly, the controller being configured to determine when the basket assembly is experiencing the plugged condition based at least in part on the detection range metric.

3. The system of claim 2 , wherein the controller is configured to compare the calculated detection range metric to a predetermined threshold, the controller being configured to determine that the basket assembly is experiencing the plugged condition when the detection range metric crosses the predetermined threshold.

4. The system of claim 2 , wherein the given location comprises a center of the basket assembly.

5. The system of claim 1 , wherein the controller is configured to determine when the basket assembly is experiencing the plugged condition by identifying variations in a profile of the data received from the range sensor as the basket assembly is being rotated.

6. The system of claim 5 , wherein the basket assembly comprises a plurality of spaced apart bars surrounding the interior of the basket, each of the plurality of spaced apart bars passing through a line of detection along which the detection signals are transmitted towards the interior of the basket assembly as the basket assembly is being rotated.

7. The system of claim 6 , wherein the controller is configured to compare the profile of the data to a non-plugged data profile, the non-plugged data profile comprising a periodic profile characterized by the deflection signals alternating between reflecting off of the plurality of spaced apart bars and being transmitted between adjacent bars of the plurality of spaced apart bars into the interior of the basket assembly.

8. The system of claim 1 , wherein the basket assembly comprises a plurality of lateral basket sections, with each lateral basket section being defined between adjacent support plates of the basket assembly, and wherein the range sensor comprises one of a plurality of range sensors installed relative to the basket assembly, the plurality of range sensors being positioned relative to the basket assembly such that at least one range sensor of the plurality of range sensors is configured to transmit detection signals towards a portion of the interior of the basket assembly defined by a respective lateral basket section of the plurality of lateral basket sections.

9. The system of claim 8 , wherein the controller is further configured to determine when a given lateral basket section of the plurality of lateral basket sections is experiencing a plugged condition by analyzing the data received from the at least one range sensor transmitting detection signals towards the portion of the interior of the basket assembly defined by such lateral basket section.

10. The system of claim 1 , wherein the range sensors comprises at least one of an optical range sensor or an ultrasonic-based range sensor.

11. An agricultural implement, comprising:
a frame;
a basket assembly configured to be supported by the frame;
a range sensor supported relative to the basket assembly such that the range sensor has a line of detection directed towards an interior of the basket assembly, the range sensor configured to generate data associated a distance between the range sensor and at least one surface aligned with the line of detection as the basket assembly is rotated relative to the range; and
a controller communicatively coupled to the range sensor, the controller configured to analyze the data received from the range sensor to determine when the basket assembly is experiencing a plugged condition.

12. A method for monitoring plugging of basket assemblies of agricultural implements, the method comprising:
transmitting, with a range sensor, detection signals towards an interior of a basket assembly of an agricultural implement as the basket assembly is rotating;
receiving return signals based on reflection of the detection signals off at least one surface; and
analyzing, with a computing device, data associated at least in part with the return signals to determine when the basket assembly is experiencing a plugged condition.

13. The method of claim 12 , further comprising controlling an operation of the agricultural implement to adjust an operating parameter associated with the agricultural implement when it is identified that the basket assembly is experiencing the plugged condition.

14. The method of claim 12 , further comprising notifying an operator of the agricultural implement when it is identified that the basket assembly is experiencing the plugged condition.

15. The method of claim 12 , further comprising determining a detection range metric indicative of a percentage of the detection signals that reach at least one of a given location within the interior of the basket assembly or a range of locations defined relative to the given location within the interior of the basket assembly.

16. The method of claim 15 , wherein analyzing the data received from the range sensor comprises comparing the detection range metric to a predetermined threshold to determine when the basket assembly is experiencing the plugged condition.

17. The method of claim 15 , wherein the given location comprises a center of the basket assembly.

18. The method of claim 12 , wherein analyzing the data received from the range sensor comprises identifying variations in a profile of the data received from the range sensor to determine when the basket assembly is experiencing the plugged condition.

19. The method of claim 18 , wherein identifying variations in the profile of the data received from the range sensor comprises analyzing the profile of the data in view of a non-plugged data profile associated with operation of the basket assembly in a non-plugged state.

20. The method of claim 15 , wherein the range sensors comprises at least one of an optical range sensor or an ultrasonic-based range sensor.
