Abstract

A particulate material agitation control system includes a metering system and an agitation control system. The metering system includes a first meter at a first position of the metering system and a second meter at a second position of the metering system. The agitation control system an agitating system and a controller having a memory and a processor. The agitating system includes a drive system. The controller is configured to determine a first output amount of particulate material at the first position, determine a second output amount of the particulate material at the second position, determine whether a difference between the first output amount and the second output amount is greater than an output difference threshold value, and output an activation signal to the agitating system indicative of instructions to activate the drive system in response to determining that the difference between the first output amount and the second output amount is greater than the output difference threshold value.

First claim

The invention claimed is:

1. A particulate material agitation control system, comprising:
a metering system comprising a first meter having a first inlet disposed at a first position of the metering system and a second meter having a second inlet disposed at a second position of the metering system; and
an agitation control system comprising:
an agitating system comprising at least one drive system connected to an agitator; and
a controller comprising a memory and a processor, wherein the controller is configured to:
determine a first output amount of particulate material at the first position;
determine a second output amount of the particulate material at the second position;
determine whether a difference between the first output amount and the second output amount is greater than an output difference threshold value; and
output an activation signal to the agitating system indicative of instructions to activate the at least one drive system in response to determining that the difference between the first output amount and the second output amount is greater than the output difference threshold value;

wherein the first and second inlets are positioned and configured for receiving particulate material that has passed through the agitation system.

2. The particulate material agitation control system of claim 1 , wherein the activation signal is configured to induce the drive system to move the particulate material toward the first position or toward the second position.

3. The particulate material agitation control system of claim 1 , wherein the activation signal is configured to induce the drive system to turn the agitator of the agitating system for a number of revolutions, an amount of time, or a combination thereof.

4. The particulate material agitation control system of claim 1 , wherein the first meter comprises a first meter roller configured to move the particulate material through the first meter, and the second meter comprises a second meter roller configured to move the particulate material through the second meter.

5. The particulate material agitation control system of claim 4 , comprising a first motor coupled to the first meter roller and a second motor coupled to the second meter roller, wherein the first motor is configured to control the first meter roller to control the first output amount, and the second motor is configured to control the second meter roller to control the second output amount.

6. The particulate material agitation control system of claim 1 , wherein the controller is configured to automatically determine the output difference threshold value based on a type of particulate material, a size of the agitating system, or a combination thereof.

7. The particulate material agitation control system of claim 1 , wherein the first position is at a first lateral end of the agitating system, the second position is at a second lateral end of the agitating system, and the first lateral end is opposite the second lateral end.

8. A particulate material agitation control system of claim 1 , wherein the activation signal is configured to cause the agitator to move the particulate material in a first direction in response to determining that the second amount is greater than the first amount, and the activation signal causes the agitating system to move the particulate material in a second direction in response to determining that the first amount is greater than the second amount.

9. A particulate material agitation control system, comprising:
a storage tank comprising a first sidewall and a second sidewall;
a camera sensor; and
an agitation control system, comprising:
an agitating system comprising at least one drive system and at least one agitator; and
a controller comprising a memory and a processor, wherein the controller is configured to:
receive from the camera sensor a camera sensor signal indicative of a first level of particulate material at the first sidewall and a second level of the particulate material at the second sidewall;
determine whether a difference between the first level and the second level is greater than a level difference threshold value; and
output an activation signal to the at least one drive system indicative of instructions to activate of the at least one agitator in response to determining that the difference between the first level and the second level is greater than the level difference threshold value
wherein the activation signal is configured to cause the agitator to move the particulate material toward the first sidewall in response to determining that the second level is greater than the first level, and the activation signal causes the agitating system to move the particulate material toward the second sidewall in response to determining that the first level is greater than the second level.

10. The particulate material agitation control system of claim 9 , wherein the camera sensor is disposed above the agitating system, wherein the controller is configured to receive the first camera sensor signal and the second camera sensor signal from the camera sensor.

11. The particulate material agitation control system of claim 9 , wherein the first sidewall comprises a first set of markings, labels, stickers, or a combination thereof, the second sidewall comprises a second set of markings, labels, stickers, or a combination thereof, and the first set and the second set are configured to indicate the first level of the particulate material and the second level of the particulate material, respectively.

12. The particulate material agitation control system of claim 10 , wherein the camera sensor signal comprises an image of the particulate material, the first sidewall, and the second sidewall.

13. The particulate material agitation control system of claim 10 , wherein the camera sensor is configured to detect the first level and the second level based on a difference in color between the particulate material and the storage tank.

14. The particulate material agitation control system of claim 10 , wherein the activation signal is configured to cause the agitator to move the particulate material until the difference between the first level and the second level is less than the level difference threshold value.

15. A particulate material agitation control system, comprising:
a metering system comprising a plurality of meters;
at least one of a tank or hopper; and
an agitation control system comprising:
an agitation system comprising an agitator and at least one drive system connected to the agitator; and
a controller comprising a memory and a processor, wherein the controller is configured to:
determine a measured profile in the at least one of a tank or hopper based on feedback from at least one sensor on a plurality of output amounts from respective meters of the plurality meters;
determine whether a variation between the measured profile and a target profile is greater than a profile variation threshold value; and
output an activation signal to the at least one drive system indicative of activation of the agitator in response to determining that the variation between the measured profile and the target profile is greater than the profile variation threshold value;
wherein the plurality of meters are positioned and configured for receiving particulate material that has passed through the agitation system.

16. The particulate material agitation control system of claim 15 , wherein the controller is configured to determine the output amount of each meter of the plurality of meters based on an activation, deactivati
