Abstract
An agricultural system includes a controller comprising a memory and a processor. The controller is configured to receive a sensor signal, determine a current flow based on the sensor signal, determine whether the current flow exceeds a current threshold for a time threshold, and operate a drive system of the agricultural system in an alternative operation instead of a normal operation in response to determining the current flow exceeds the current threshold for the time threshold.
Claims18
An agricultural system, comprising:
- a controller comprising a memory and a processor, wherein the controller is configured to:
- receive a sensor signal;
- determine a mathematical mean of a current flow for a time interval based on the sensor signal;
- determine whether the mathematical mean of the current flow exceeds a current threshold for a time threshold;
- and
- operate a drive system of the agricultural system in an alternative operation instead of a normal operation in response to determining the mathematical mean of the current flow exceeds the current threshold for the time threshold.
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 a sensor signal from a sensing system, wherein the sensor signal is indicative of a current flow through an agitator drive system of an agricultural system;
- determine the current flow based on the sensor signal;
- determine whether the current flow exceeds a first current threshold for a first time threshold;
- operate the agitator drive system in a normal operation in response to determining the current flow does not exceed the first current threshold for the first time threshold, wherein the normal operation comprises a duty cycle comprising an alternation between an active time of the agitator drive system and an inactive time of the agitator drive system to establish a ratio between the active time and a total time of operation of the agitator drive system;
- and
- operate the agitator drive system in an alternative operation instead of the normal operation in response to determining the current flow exceeds the first current threshold for the first time threshold, wherein the alternative operation comprises a reduced duty cycle comprising a reduced ratio between the active time and the total time of operation of the agitator drive system.
An agricultural system, comprising:
- an agitator configured to induce movement of particulate material through the agricultural system;
- a drive system configured to couple to the agitator, wherein the drive system is configured to receive a current flow and to drive the agitator to move;
- a sensing system configured to output a sensor signal indicative of the current flow through the drive system;
- and
- a controller communicatively coupled to the sensing system and comprising a memory and a processor, wherein the controller is configured to:
- receive the sensor signal;
- determine an average current flow based on the sensor signal;
- determine whether the average current flow exceeds a first current threshold for a first time threshold;
- and
- reduce a duty cycle of the drive system from a normal duty cycle to a reduced duty cycle in response to determining the average current flow exceeds the first current threshold for the first time threshold, wherein the duty cycle comprises an alternation between an active time of the drive system and an inactive time of the drive system, and reducing the duty cycle comprises reducing a ratio between the active time and a total time of operation of the drive system.
