Abstract

A particulate material sensing and agitation control system of an agricultural system having a drive system configured to operate an agitating system, and a controller having a memory and a processor. The controller is configured to receive at least one sensor signal indicative of a profile of a particulate material within the agricultural system, and output a control signal to instruct the drive system to operate the agitating system in a selected operating mode of a plurality of operating modes based on the profile of the particulate material. The agitating system is configured to interact with the particulate material in each operating mode of the plurality of operating modes, and the plurality of operating modes includes an agitation mode and a leveling mode.

First claim

The invention claimed is:

1. A particulate material sensing and agitation control system of an agricultural system, comprising:
a drive system configured to operate an agitating system, wherein the agitating system comprises an agitator; and
a controller comprising a memory and a processor, wherein the controller is configured to:
receive at least one sensor signal indicative of a profile of a particulate material within the agricultural system; and
output a control signal to instruct the drive system to operate the agitating system in a selected operating mode of a plurality of operating modes based on the profile of the particulate material, wherein the agitating system is configured to interact with the particulate material in each operating mode of the plurality of operating modes, the plurality of operating modes comprises an agitation mode and a leveling mode, and the drive system is configured to cyclically rotate the agitator in a first rotational direction for a first time and in a second rotational direction, opposite the first rotational direction, for a second time while the agitating system is operating in each operating mode of the plurality of operating modes.

2. The particulate material sensing and agitation control system of claim 1 , wherein the leveling mode comprises a symmetric leveling mode, a heavily biased leveling mode, a moderately biased leveling mode, a slightly biased leveling mode, or any combination thereof.

3. The particulate material sensing and agitation control system of claim 2 , wherein the drive system is configured to cyclically rotate the agitator in the first rotational direction for the first time, maintain a position of the agitator for a first dwell time, rotate the agitator in the second rotational direction for the second time, and maintain another position of the agitator for a second dwell time while the agitating system is operating in each operating mode of the plurality of operating modes.

4. The particulate material sensing and agitation control system of claim 3 , wherein the agitation mode comprises an approximately equal first time and second time, the symmetric leveling mode comprises an approximately equal first time and second time, the heavily biased leveling mode comprises a first difference between the first time and the second time of 23 seconds to 57 seconds, the moderately biased leveling mode comprises a second difference between the first time and the second time of 5 seconds to 27 seconds, and the slightly biased leveling mode comprises a third difference between the first time and the second time of 1 second to 4 seconds.

5. The particulate material sensing and agitation control system of claim 1 , wherein the controller is configured to determine whether a metering system of the agricultural system is active, and, in response to determining the metering system is active, the controller is configured to output the control signal to instruct the drive system to operate the agitating system in the selected operating mode of the plurality of operating modes.

6. The particulate material sensing and agitation control system of claim 5 , wherein, in response to determining the metering system is not active, the controller is configured to output an additional signal to instruct the drive system to operate the agitating system in a door-dump mode.

7. The particulate material sensing and agitation control system of claim 6 , wherein the additional signal instructs the drive system to operate the agitating system in the door-dump mode for a time duration based on the profile of the particulate material.

8. At least one non-transitory computer readable medium comprising executable instructions that, when executed by a processor, are configured to cause the processor to:
receive at least one sensor signal from a plurality of sensors, wherein the at least one sensor signal is indicative of a profile of a particulate material within an agricultural system; and
output a control signal to instruct a drive system of the agricultural system to operate an agitating system in a selected operating mode of a plurality of operating modes based on the profile of the particulate material, wherein the agitating system is configured to interact with the particulate material in each operating mode of the plurality of operating modes, the agitating system comprises an agitator, and the control signal instructs the drive system to operate the agitating system to cyclically rotate the agitator in a first rotational direction for a first time and in a second rotational direction, opposite the first rotational direction, for a second time while the agitating system is operating in each operating mode of the plurality of operating modes.

9. The at least one non-transitory computer readable medium of claim 8 , wherein the executable instructions are configured to cause the processor to select an agitation mode as the selected operating mode in response to receiving the at least one sensor signal indicating that each sensor of the plurality of sensors detects the particulate material.

10. The at least one non-transitory computer readable medium of claim 8 , wherein the executable instructions are configured to cause the processor to select a symmetric operating mode as the selected operating mode in response to receiving the at least one sensor signal indicating that outermost sensors of the plurality of sensors detect the particulate material and a middle sensor of the plurality of sensors does not detect the particulate material, or that the outermost sensors do not detect the particulate material and the middle sensor detects the particulate material.

11. The at least one non-transitory computer readable medium of claim 8 , wherein the executable instructions are configured to cause the processor to select a heavily biased operating mode as the selected operating mode in response to receiving the at least one sensor signal indicating that a middle sensor detects the particulate material, that one or more sensors of a first side of the middle sensor detect the particulate material, and that one or more sensors of a second side of the middle sensor do not detect the particulate material.

12. The at least one non-transitory computer readable medium of claim 8 , wherein the executable instructions are configured to cause the processor to select a moderately biased operating mode as the selected operating mode in response to receiving the at least one sensor signal indicating that a middle sensor does not detect the particulate material, that one or more sensors of a first side of the middle sensor detect the particulate material, and that one or more sensors of a second side of the middle sensor do not detect the particulate material.

13. The at least one non-transitory computer readable medium of claim 8 , wherein the executable instructions are configured to cause the processor to determine whether a previous selected operating mode is a moderately biased leveling mode in response to receiving the at least one sensor signal indicating that none of the sensors of the plurality of sensors detect the particulate material, and the executable instructions are configured to cause the processor to select a slightly biased leveling mode as the selected operating mode in response to determining the previous selected operating mode is the moderately biased leveling mode.

14. The at least one non-transitory computer readable medium of claim 13 , wherein the executable instructions are configured to cause the processor to select a symmetric leveling mode as the selected operating mode in response to determining that the previous op
