Abstract

A particulate material sensing and agitation control system of an agricultural system includes a drive system configured to operate an agitating system, a plurality of sensors, in which each sensor of the plurality of sensors may detect presence of particulate material at the sensor, and a controller. The controller is configured to determine a functional status of each sensor of the plurality of sensors, and, in response to determining the functional status of a respective sensor of the plurality of sensor is functioning, determine a detection status of the respective sensor. The controller is further configured to 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 a position within the agricultural system, the functional status, and the detection status of each sensor of the plurality of sensors.

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;
a plurality of sensors, wherein each sensor of the plurality of sensors is configured to detect presence of particulate material at the sensor; and
a controller comprising a memory and a processor, wherein the controller is configured to:
determine a functional status of each sensor of the plurality of sensors;
in response to determining the functional status of a respective sensor of the plurality of sensor is functioning, determine a detection status of the respective sensor; 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 a position within the agricultural system, the functional status, and the detection status of each sensor of the plurality of sensors.

2. The particulate material sensing and agitation control system of claim 1 , wherein the controller selects an agitation mode as the selected operating mode in response to determining that the functional status of one of the sensors of the plurality of sensors is non-functioning, and the detection status of the remaining sensors of the plurality of sensors is positive.

3. The particulate material sensing and agitation control system of claim 1 , wherein the controller selects a symmetric leveling mode as the selected operating mode in response to determining that the functional status of one of the sensors of the plurality of sensors is non-functioning, and the detection status of the remaining sensors of the plurality of sensors is negative.

4. The particulate material sensing and agitation control system of claim 1 , wherein the controller selects a biased leveling mode as the selected operating mode in response to determining that the functional status of a middle sensor of the plurality of sensors is non-functioning, the detection status of one or more sensors of a first side of the middle sensor is positive, and the detection status of one or more sensors of a second side of the middle sensor is negative.

5. The particulate material sensing and agitation control system of claim 1 , wherein the controller selects a symmetric leveling mode as the selected operating mode in response to determining that the functional status of an outmost sensor of the plurality of sensors is non-functioning, the detection status of one or more remaining sensors of the plurality of sensors is positive, and the detection status of one or more remaining sensors of the plurality of sensors is negative.

6. The particulate material sensing and agitation control system of claim 1 , wherein the controller selects an agitation mode as the selected operating mode in response to determining that the functional status of more than one sensor of the plurality of sensors is non-functioning.

7. The particulate material sensing and agitation control system of claim 1 , wherein the controller is configured to determine if a metering system of the particulate material sensing and agitation control system is active, the controller is configured to output the signal to instruct the drive system to operate the agitating system in the operating mode in response to determining the metering system is active, and the controller is configured to output an additional signal to instruct the drive system to operate the agitating system in a door-dump mode in response to determining the status of the metering system is inactive.

8. The particulate material sensing and agitation control system of claim 7 , wherein the additional signal instructs the drive system to operate the agitating system in the door-dump mode for a time duration based on if the respective sensors of the plurality of sensors are functioning, if the respective sensors detect the particulate material, or any combination thereof.

9. A particulate material sensing and agitation control system of an agricultural system, comprising:
a metering system configured to meter particulate material to a distribution system;
an agitating system configured to direct the particulate material to the metering system;
a plurality of sensors, wherein each sensor of the plurality of sensors is configured to detect presence of the particulate material at the sensor;
a controller comprising a memory and a processor, wherein the controller is configured to:
determine a status of the metering system, wherein the status comprises an active mode and an inactive mode;
determine a functional status of each sensor of the plurality of sensors, wherein each sensor of the plurality of sensors is configured to detect presence of the particulate material at the sensor;
in response to determining the functional status of a respective sensor of the plurality of sensor is functioning, determine a detection status of the respective sensor; and
output a control signal to instruct a drive system to operate the agitating system in a selected mode of a plurality of modes based on the status of the metering system, the functional status of each sensor of the plurality of sensors, and the detection status of each sensor of the plurality of sensors.

10. The particulate material sensing and agitation control system of claim 9 , wherein the controller is configured to select an operating mode of a plurality of operating modes as the selected mode in response to determining the status of the metering system is active and based on the functional status and detection status of each sensor of the plurality of sensors, wherein the plurality of operating modes comprises an agitation mode, a symmetric leveling mode, a slightly biased leveling mode, a moderately biased leveling mode, a heavily biased leveling mode, or any combination thereof.

11. The particulate material sensing and agitation control system of claim 9 , wherein the controller is configured select a door-dump mode as the selected mode in response to determining the status of the metering system is inactive, wherein a time duration of the door-dump mode is based on the functional status and the detection status of each sensor of the plurality of sensors.
