Abstract

Systems and methods are provided for monitoring and controlling operation a conditioning system of or otherwise associated with an agricultural machine, which may include a mower conditioner. Sensor data indicative of a displacement associated with component(s) of the conditioning system is used to determine a measured displacement, which is compared with a target displacement for the component(s) and such a comparison is used to control an operational speed of one or more components associated with the conditioning system. The controllable component(s) can include the conditioning component(s), and the one or more controllers may be used to control the operational speed of the conditioning components and ultimately a level of conditioning applied to cut crop material passing through the conditioning system.

First claim

What is claimed is:

1 . A control system for adjusting a level of conditioning applied by a conditioning system of or otherwise associated with an agricultural machine, the control system comprising one or more controllers, and being configured to:
receive sensor data indicative of a displacement associated with one or more conditioning components of the conditioning system; determine a measured displacement in dependence on the received data; compare the measured displacement with a target displacement for the conditioning component(s); and generate and output one or more control signals for controlling an operational speed of one or more components associated with the conditioning system in dependence on the comparison.

2 . A control system of claim 1 , wherein the one or more conditioning components comprise one or more conditioning rollers.

3 . A control system of claim 2 , wherein the one or more conditioning components comprise a pair of conditioning rollers.

4 . A control system of claim 2 , wherein the measured displacement comprises a roller gap.

5 . A control system of claim 1 , wherein the sensor data is received from one or more sensors mounted or otherwise coupled in association with the conditioning system for monitoring one or more parameters associated with the operation of the conditioning system.

6 . A control system of claim 5 , wherein the one or more sensors include a rotary potentiometer providing a comparable sensor output in dependence on the position of the one or more conditioning components.

7 . A control system of claim 1 , wherein the target displacement comprises a set value or a range about a defined set displacement value within which the measured displacement of the conditioning component(s) is deemed acceptable and no adjustments may be made to the operational speed of the controllable component(s).

8 . A control system of claim 1 , wherein the target displacement is predefined, is determined in dependence on a crop type to be processed by the conditioning system, and/or is determined in dependence on a user input.

9 . A control system of claim 1 , wherein controlling the operational speed of the component(s) associated with the conditioning system includes controlling an operational speed of the one or more conditioning components.

10 . A control system of claim 9 , wherein the one or more conditioning components comprise one or more conditioning rollers, and wherein the one or more controllers are configured to control the operational speed of the conditioning roller(s) in dependence on the comparison.

11 . A control system of claim 8 , wherein controlling the operational speed of the component(s) associated with the conditioning system comprises controlling a feed rate of crop material to and/or through the conditioning system.

12 . A control system of claim 11 , wherein the one or more controllers are configured to control an operational speed of a feed roller for controlling a feed rate of material to the conditioning system.

13 . A conditioning system for an agricultural machine, comprising:
one or more moveable crop engaging components; and the control system of any preceding claim , operable in use for controlling an operational speed of one or more components associated with the conditioning system to control a level of conditioning applied by the one or more moveable crop engaging components in dependence on a comparison of a measured displacement of the crop engaging component(s) with a target displacement.

14 . An agricultural machine comprising the conditioning system of claim 13 .

15 . An agricultural machine comprising or being controllable under operation of the control system of claim 1 .

16 . A computer implemented method for adjusting a level of conditioning applied by a conditioning system of or otherwise associated with an agricultural machine, the method comprising:
determining a measured displacement associated with one or more components of the conditioning system; comparing the measured displacement with a target displacement for the component(s); and controlling an operational speed of one or more component(s) associated with the conditioning system in dependence on the comparison.
