Abstract

A control or regulating system for an agricultural working machine is provided, the system comprising a plurality of actuating elements that can be controlled individually or in groups, at least one control unit for receiving and/or sending switching commands to control the actuating elements, wherein the switching commands have at least one setting parameter setting and/or configuring the actuating elements, and at least one signal line to connect at least two actuating elements to the control unit for signal transmission. The switching commands are combined into at least one common group switching command that is transmitted via the at least one signal line, and the actuating elements are set and/or configured by the at least one group switching command. In turn, the efficiency and dependability of previous control or regulating systems is improved in a simple manner.

First claim

The invention claimed is:

1 . A control or regulating system for an agricultural working machine comprising:
a plurality of actuating elements which are controllable individually or in groups, at least one control unit associated with the actuating elements, wherein the control unit is configured to at least one of receive and send switching commands for controlling the actuating elements, wherein the switching commands have at least one setting parameter for at least one of setting and configuring the actuating elements, and at least one signal line configured to connect at least two of the actuating elements to the control unit for signal transmission, wherein the switching commands are combinable to form at least one common group switching command that is transmittable by way of the at least one signal line, and in that the actuating elements are configured to be at least one of settable and configurable by means of the at least one common group switching command, the at least one common group switching command comprises at least one of a first and second identifier associated with respective actuating elements, wherein at least one of the actuating elements having an identifier matching at least one of the first and second identifier or lying between the first and second identifier is configured to be at least one of settable and configurable using the at least one common group switching command, the at least one common group switching command comprises at least one setting parameter having at least one of a start and end value, wherein at least one actuating element having at least one of the first and second identifier is configured to be at least one of settable and configurable using at least one of the start value and end value, wherein the control unit is configured to control the plurality of actuating elements using the at least one common group switching command.

2 . The control or regulating system according to claim 1 , wherein the control or regulating system is a bus system.

3 . The control or regulating system according to claim 2 , wherein the bus system is a CAN bus system.

4 . The control or regulating system according to claim 1 , wherein the at least one common group switching command provided for the at least two actuating elements comprises the at least one setting parameter having the start and end value, wherein the actuating element of the at least two actuating elements having the first identifier is configured to be at least one of settable and configurable using the start value, and the actuating element of the at least two actuating elements having the second identifier is configured to be at least one of settable and configurable using the end value.

5 . The control or regulating system according to claim 1 , wherein the at least one actuating element having the identifier lying between the first and second identifier is configured to be at least one of settable and configurable using at least one intermediate value lying between the start and end value.

6 . The control or regulating system according to claim 1 , wherein the actuating elements are controllable using at least one of a pulse width modulation and pulse width frequency modulation.

7 . The control or regulating system according to claim 6 , wherein the at least one common group switching command comprises at least one of a pulse width and pulse frequency.

8 . The control or regulating system according to claim 7 , wherein the at least one setting parameter comprises at least one of the pulse width and pulse frequency.

9 . The control or regulating system according to claim 7 , wherein the at least one common group switching command comprises at least one of a range of the pulse width and pulse frequency.

10 . The control or regulating system according to claim 1 , wherein the agricultural working machine is a distribution machine for spreading material over an agricultural area.

11 . An agricultural working machine having a control or regulating system, the control or regulating system comprising:
a plurality of actuating elements which are controllable individually or in groups, at least one control unit associated with the actuating elements, wherein the control unit is configured to at least one of receive and send switching commands for controlling the actuating elements, wherein the switching commands have at least one setting parameter for at least one of setting and configuring the actuating elements, and at least one signal line configured to connect at least two of the actuating elements to the control unit for signal transmission, wherein the switching commands are combinable to form at least one common group switching command that is transmittable by way of the at least one signal line, and in that the actuating elements are configured to be at least one of settable and configurable by means of the at least one common group switching command, the at least one common group switching command comprises at least one of a first and second identifier associated with respective actuating elements, wherein at least one of the actuating elements having an identifier matching at least one of the first and second identifier or lying between the first and second identifier is configured to be at least one of settable and configurable using the at least one common group switching command, the at least one common group switching command comprises at least one setting parameter having at least one of a start and end value, wherein at least one actuating element having at least one of the first and second identifier is configured to be at least one of settable and configurable using at least one of the start value and end value, wherein the control unit is configured to control the plurality of actuating elements using the at least one common group switching command.

12 . The agricultural working machine according to claim 11 , wherein the working machine is configured as a towed, carried, or self-propelled field sprayer for spreading spraying medium, comprising:
at least one storage container for storing the spraying medium, a linkage extending transversely to a direction of travel, at least one of spray nozzles, the spray nozzles arranged on the linkage, and valves associated with the spray nozzles for spreading the spray medium, and a conveying system, configured to supply the spraying medium to at least one of the valves and spray nozzles from the at least one storage container in at least one of an adjustable amount and at an adjustable pressure.

13 . The agricultural working machine according to claim 12 , wherein an amount of spraying medium spread by at least one of the spray nozzles and valves are settable individually, wherein the at least one common group switching command comprises the at least one setting parameter influencing at least one of a pressure and the amount of the spraying medium.

14 . The agricultural working machine according to claim 12 , wherein the valves are solenoid valves.

15 . The agricultural working machine according to claim 12 , wherein the amount of spraying medium spread by at least one of the spray nozzles and valves are settable in a partial-surface-specific manner.

16 . A method for operating an agricultural working machine having a control or regulating system, the control or regulating system comprising: a plurality of actuating elements which are controllable individually or in groups, at least one control unit associated with the actuating elements, wherein the control unit is configured to at least one of receive and send
