Abstract

A control system for an agricultural system includes a first controller configured to receive sensor information from a plurality of sensors, in which the sensor information is indicative of a height of a header of the agricultural system, and the first controller is configured to convert the sensor information into position data. The control system further includes a second controller communicatively coupled to the first controller, in which the second controller is configured to receive the position data from the first controller, and the second controller is configured to determine a target position of the header based on the position data.

Claims (38)

1. A control system for an agricultural system, comprising:

a first controller configured to receive sensor information from a plurality of sensors, wherein the sensor information is indicative of a height of a header of the agricultural system, and the first controller is configured to convert the sensor information into position data; and

a second controller communicatively coupled to the first controller, wherein the second controller is configured to receive the position data from the first controller, and the second controller is configured to determine a target position of the header based on the position data;

wherein the first controller is configured to instruct a first actuator of the header to adjust a first header segment of the header relative to a second header segment of the header, and the second controller is configured to instruct a second actuator of the header to adjust the header relative to a chassis of the agricultural system.

2. The control system of claim 1 , wherein the sensor information comprises first data associated with a first plurality of header sections of the header, the position data comprises second data associated with a second plurality of header sections of the header, and the first plurality of header sections is different than the second plurality of header sections.

3. The agricultural system of claim 2 , wherein the first plurality of header sections comprises a different number of header sections than the second plurality of header sections.

4. The control system of claim 3 , wherein the first plurality of header sections comprises eight header sections, and the second plurality of header sections comprises four header sections.

5. The control system of claim 1 , wherein the sensor information comprises a first operating parameter, the position data comprises a second operating parameter, and the first operating parameter is different than the second operating parameter.

6. The control system of claim 1 , wherein the plurality of sensors comprises a contact sensor, a proximity sensor, or both.

7. The control system of claim 1 , wherein the first controller is configured to set a position of the first header segment of the header relative to the second header segment of the header based on the sensor information and to utilize the position to instruct the first actuator of the header to adjust the first header segment of the header relative to the second header segment of the header.

8. The control system of claim 1 , wherein the second controller is configured to set a position of the header relative to a chassis of the agricultural system based on the target position of the header and to utilize the position to instruct the second actuator of the header to adjust the header relative to the chassis of the agricultural system.

9. The control system of claim 8 , wherein the header is coupled to the chassis of the agricultural system, and the second controller is configured to raise, lower, tilt, maintain, or any combination thereof, a center segment of the header relative to the chassis toward the target position of the header.

10. The control system of claim 1 , wherein the second controller is configured to:

while the header is coupled to a chassis of the agricultural system over a first time period, receive the position data from the first controller and determine the target position of the header based on the position data received from the first controller; and

while an additional header is coupled to the chassis of the agricultural system over a second time period, receive additional sensor information from an additional plurality of sensors and determine an additional target position of the additional header based on the additional sensor information received from the additional plurality of sensors.

11. The control system of claim 1 , wherein the first controller is configured to instruct the first actuator to adjust the first header segment relative to the second header segment based on the sensor information, and the second controller is configured to instruct the second actuator to adjust the header relative to the chassis based on the position data.

12. The control system of claim 1 , wherein the first controller is configured to:

determine the target position of the header based on the sensor information; and

convert the sensor information into the position data based on the sensor information to cause the second controller to determine the target position of the header based on the position data.

13. The control system of claim 1 , wherein the first controller is configured to:

determine a plurality of values indicative of respective height values of a plurality of header sections of the header; and

include the plurality of values in the position data.

14. The control system of claim 1 , wherein the sensor information comprises a first reading at a first portion of the header and a second reading at a second portion of the header, and the first controller is configured to:

graphically plot the first reading and the second reading against the first portion and the second portion of the header;

perform a regression analysis to determine a relationship between the first reading at the first portion and the second reading at the second portion;

determine, based on the relationship, a third reading representative of a third position of the header; and

include the third reading in the position data.

15. A control system for an agricultural system, comprising:

a first controller configured to:

receive sensor information from a plurality of sensors, wherein the sensor information is indicative of a height of a header of the agricultural system, and the header is coupled to a chassis of the agricultural system;

convert the sensor information into position data; and

set a position of a first header segment of the header relative to a second header segment of the header based on the sensor information; and

a second controller communicatively coupled to the first controller, wherein the second controller is configured to:

receive the position data from the first controller;

determine a target position of the header based on the position data;

set a position of the header relative to the chassis of the agricultural system based on the target position of the header; and

raise, lower, tilt, maintain, or any combination thereof, a center segment of the header relative to the chassis toward the target position of the header.

16. The control system of claim 1 , wherein the header is coupled to a chassis of the agricultural system, and the second controller is configured to raise, lower, tilt, maintain, or any combination thereof, a center segment of the header relative to the chassis toward the target position of the header.
