Abstract

A system for controlling a ground speed of an agricultural sprayer includes a boom and a nozzle mounted on the boom. The nozzle, in turn, is configured to dispense a fan of an agricultural fluid as the agricultural sprayer travels across a field. Additionally, the system includes a sensor configured to capture data indicative of a spray quality parameter associated with the dispensed fan of the agricultural fluid. Furthermore, the system includes a controller communicatively coupled to the sensor. As such, the controller is configured to receive the captured data from the sensor as the agricultural sprayer travels across the field. Moreover, the controller is configured to determine the spray quality parameter based on the received data. In addition, the controller is configured to control a ground speed of the agricultural sprayer based on the determined spray quality parameter.

Claims (22)

1. A system for controlling a ground speed of an agricultural sprayer, the system comprising:

a boom;

a nozzle mounted on the boom, the nozzle configured to dispense a fan of an agricultural fluid as the agricultural sprayer travels across a field;

a sensor mounted on the boom, the sensor configured to capture data indicative of an air speed of air flowing past the boom as the agricultural sprayer travels across the field; and

a controller communicatively coupled to the sensor, wherein the controller:

receives the captured data from the sensor as the agricultural sprayer travels across the field;

determines the air speed of the air flowing past the boom as the agricultural sprayer travels across the field based on the received data;

compares the determined air speed of the air flowing past the boom as the agricultural sprayer travels across the field a predetermined air speed range;

monitors a time period across which the determined air speed of the air flowing past the boom as the agricultural sprayer travels across the field is within the predetermined air speed range; and

initiates an increase in the ground speed of the agricultural sprayer when the determined air speed of the air flowing past the boom as the agricultural sprayer travels across the field is within the predetermined air speed range across a predetermined time period.

2. The system of claim 1 , wherein the controller initiates a reduction in the ground speed of the agricultural sprayer when the determined air speed of the air flowing past the boom as the agricultural sprayer travels across the field falls below a minimum value of the predetermined air speed range.

3. The system of claim 1 , wherein the controller receives an input associated with the predetermined air speed range from an operator of the agricultural sprayer.

4. A method for controlling a ground speed of an agricultural sprayer, the agricultural sprayer including a boom and a nozzle mounted on the boom, the nozzle configured to dispense a fan of an agricultural fluid as the agricultural sprayer travels across a field, the method comprising:

receiving, with a controller, sensor data indicative of an air speed of air flowing past the boom as the agricultural sprayer travels across the field from a sensor mounted on the boom;

determining, with the controller, the air speed of the air flowing past the boom as the agricultural sprayer travels across the field based on the received sensor data;

comparing, with the controller, the determined air speed of the air flowing past the boom as the agricultural sprayer travels across the field to a predetermined air speed range;

monitoring, with the controller, a time period across which the determined air speed of the air flowing past the boom as the agricultural sprayer travels across the field is within the predetermined air speed range; and

initiating, with the controller, an increase in the ground speed of the agricultural sprayer when the determined air speed of the air flowing past the boom as the agricultural sprayer travels across the field is within the predetermined air speed range across a predetermined time period.

5. The method of claim 4 , further comprising:

initiating, with the controller, a reduction in the ground speed of the agricultural sprayer when the determined air speed of the air flowing past the boom as the agricultural sprayer travels across the field falls below a minimum value of the predetermined air speed range.

6. The method of claim 4 , further comprising:

receiving, with the controller, an input associated with the predetermined air speed range from an operator of the agricultural sprayer.
