Method for a spray device

A method for monitoring and/or adjusting an active agent concentration in a spray liquid to be deployed using a spray device, for agricultural purposes, an active agent and a carrier liquid being supplied to a mixing unit of the spray device to blend the spray liquid, the method comprising the following steps:

• receiving a first property signal including a piece of property information of the blended spray liquid detected using a first sensor unit, to ascertain an actual value of the property information of the spray liquid, an active agent concentration in the spray liquid being ascertainable using the property information;
• receiving a second property signal including a piece of property information of the supplied carrier liquid detected using a second sensor unit of the spray device, to ascertain a base value of the property information of the carrier liquid;
• and
• outputting an information signal to a display unit and/or a control signal to a delivery unit of the spray device, the information signal and/or the control signal being output as a function of the ascertained actual value of the property information of the spray liquid, and as a function of the ascertained base value of the property information of the carrier liquid, to monitor and/or to adjust the active agent concentration in the blended spray liquid.

A control unit configured to monitor and/or adjust an active agent concentration in a spray liquid to be deployed using a spray device, for agricultural purposes, an active agent and a carrier liquid being supplied to a mixing unit of the spray device to blend the spray liquid, the control device configured to:

• receive a first property signal including a piece of property information of the blended spray liquid detected using a first sensor unit, to ascertain an actual value of the property information of the spray liquid, an active agent concentration in the spray liquid being ascertainable using the property information;
• receive a second property signal including a piece of property information of the supplied carrier liquid detected using a second sensor unit of the spray device, to ascertain a base value of the property information of the carrier liquid;
• and
• output an information signal to a display unit and/or a control signal to a delivery unit of the spray device, the information signal and/or the control signal being output as a function of the ascertained actual value of the property information of the spray liquid, and as a function of the ascertained base value of the property information of the carrier liquid, to monitor and/or to adjust the active agent concentration in the blended spray liquid.

A spray device for deploying a spray liquid for agricultural purposes, comprising:

• a mixing unit configured to blend a spray liquid from a carrier liquid supplied to the mixing unit using a liquid delivery unit, and an active agent supplied using an active agent delivery unit;
• a first sensor unit configured to detect a piece of property information of the blended spray liquid, an active agent concentration in the spray liquid being ascertainable using the property information;
• a second sensor unit configured to detect a piece of property information of the supplied carrier liquid;
• and
• a control unit configured to monitor and/or adjust the active agent concentration in the spray liquid to be deployed, the control device configured to:
• receive a first property signal including the piece of property information of the blended spray liquid detected using the first sensor unit, to ascertain an actual value of the property information of the spray liquid;
• receive a second property signal including the piece of property information of the supplied carrier liquid detected using the second sensor unit of the spray device, to ascertain a base value of the property information of the carrier liquid;
• and
• output an information signal to a display unit and/or a control signal to the delivery unit of the spray device, the information signal and/or the control signal being output as a function of the ascertained actual value of the property information of the spray liquid, and as a function of the ascertained base value of the property information of the carrier liquid, to monitor and/or to adjust the active agent concentration in the blended spray liquid.

A non-transitory machine-readable memory medium on which is stored a computer program for monitoring and/or adjusting an active agent concentration in a spray liquid to be deployed using a spray device, for agricultural purposes, an active agent and a carrier liquid being supplied to a mixing unit of the spray device to blend the spray liquid, the computer program, when executed by a computer, causing the computer to perform the following steps:

• receiving a first property signal including a piece of property information of the blended spray liquid detected using a first sensor unit, to ascertain an actual value of the property information of the spray liquid, an active agent concentration in the spray liquid being ascertainable using the property information;
• receiving a second property signal including a piece of property information of the supplied carrier liquid detected using a second sensor unit of the spray device, to ascertain a base value of the property information of the carrier liquid;
• and
• outputting an information signal to a display unit and/or a control signal to a delivery unit of the spray device, the information signal and/or the control signal being output as a function of the ascertained actual value of the property information of the spray liquid, and as a function of the ascertained base value of the property information of the carrier liquid, to monitor and/or to adjust the active agent concentration in the blended spray liquid.
