Abstract

A spraying system for spraying a fluid includes a nozzle assembly configured to spray the fluid in response to receiving a control signal, a sensor configured to transmit a detection signal upon detection of a target, and a user interface configured to receive input from an operator. The spraying system further includes a control system communicatively coupled to the sensor to receive the detection signal from the sensor, the control system configured to transmit the control signal to the nozzle assembly at least in part in response to reception of the detection signal, the control system further configured to determine a fluid band length and an offset distance of the fluid band length from the target based at least in part on information input by the operator to the user interface. The user interface displays a graphic representation of the fluid band length and the offset distance relative to the target.

First claim

What is claimed is:

1. A spraying system for spraying a fluid comprising:
a nozzle assembly configured to spray the fluid in response to receiving a control signal;
a sensor configured to transmit a detection signal upon detection of a target;
a user interface configured to receive input from an operator; and
a control system communicatively coupled to the sensor to receive the detection signal from the sensor, the control system configured to transmit the control signal to the nozzle assembly at least in part in response to reception of the detection signal, the control system further configured to determine a fluid band length of fluid dispensed by the nozzle assembly along a direction of travel of the spraying system and an offset distance of the fluid band length from the target based at least in part on information input by the operator to the user interface;
wherein the user interface displays a graphic representation of the fluid band length and the offset distance relative to the target.

2. The spraying system of claim 1 , wherein the sensor is at least one of a break beam sensor, positioned to detect seeds dispensed by a seed tube, and a camera.

3. The spraying system of claim 1 , wherein the target is at least one of a seed, a seedling, a transplant, or an encapsulated tissue culture.

4. The spraying system of claim 1 , wherein the fluid is at least one of a fertilizer, a pesticide, an insecticide, a fungicide, a growth promoter, or growth regulator.

5. The spraying system of claim 1 , wherein the control system is configured to determine the fluid band length based on information received from the user interface including at least seed population information, application rate information, pressure set point information, and target speed information corresponding to a target travel speed of the spraying system, and wherein the offset distance is received from the user interface as an input from the operator.

6. The spraying system of claim 5 , wherein the control system is further configured to determine:
a specific volume of fluid to be applied to the target based on the seed population information and the application rate information;
a flow rate based at least in part on the pressure set point information; and
a spray duration based on the specific volume and the flow rate.

7. The spraying system of claim 6 , wherein the control system is further configured to determine the flow rate based on a geometry of at least one of a nozzle of the nozzle assembly and a spray tip of the nozzle assembly.

8. The spraying system of claim 1 , wherein the user interface is configured to display the fluid band length and the offset distance to scale.

9. The spraying system of claim 8 , wherein the user interface is configured to display the fluid band length and the offset distance to scale relative to a distance between two adjacent targets, the user interface further configured to display two images corresponding to the two adjacent targets a distance apart at the same scale.

10. The spraying system of claim 1 , wherein the control system determines the fluid band length based on an initial fluid band length and a scaling factor between 1 and 2.

11. A method for determining and displaying characteristics of a spraying system to a user of the spraying system, the spraying system configured to apply fluid to a target with a nozzle assembly including a nozzle and a valve, the method comprising:
receiving, at a control system configured to control the nozzle assembly, information from a user interface communicatively coupled to the control system, the information including target population information, application rate information, pressure set point information, and target speed information corresponding to a target travel speed of the spraying system;
determining, based at least in part on the information received from the user interface, a fluid band length of fluid dispensed by the nozzle assembly along a direction of travel of the spraying system and an offset distance between the fluid band length and the target; and
displaying, on the user interface, a graphic representation of the fluid band length and the offset distance relative to the target.

12. The method of claim 11 wherein determining the fluid band length comprises:
determining a specific volume of fluid to be applied to the target based on the target population information and application rate information;
determining a flow rate based at least in part on the pressure set point information; and
determining a spray duration based on the specific volume and the flow rate.

13. The method of claim 12 , wherein determining the fluid band length comprises determining a product of the spray duration and a velocity included in the target speed information.

14. The method of claim 12 , wherein determining the flow rate includes determining a velocity of the fluid through at least one of the nozzle or a spray tip of the nozzle assembly and determining a product of the velocity of the fluid and an area of at least one of a nozzle opening of the nozzle assembly or a spray tip opening of the nozzle assembly.

15. The method of claim 11 , wherein determining a fluid band length comprises determining an initial fluid band length and applying a scaling factor between 1 and 2.

16. The method of claim 11 , wherein displaying the graphic representation of the fluid band length and the offset distance comprises displaying the fluid band length and the offset distance to scale.

17. The method of claim 16 , wherein displaying the graphic representation of the fluid band length and the offset distance comprises displaying the graphic representation to scale relative to a distance between two adjacent targets, and displaying two images corresponding to the adjacent targets a distance apart at the same scale.

18. A planter system for planting seeds and spraying a fluid, the planter system comprising:
a seeder assembly including a seed meter configured to dispense seeds through a seed tube;
a nozzle assembly configured to spray the fluid in response to receiving a control signal;
a sensor configured to transmit a detection signal upon detection of a seed passing through the seed tube;
a user interface configured to receive input from an operator; and
a control system communicatively coupled to the sensor to receive the detection signal from the sensor, the control system configured to transmit the control signal to the nozzle assembly at least in part in response to reception of the detection signal, the control system further configured to determine a fluid band length of fluid dispensed by the nozzle assembly along a direction of travel of the planter system and an offset distance of the fluid band length from a target seed dispensed from the planter system based at least in part on information input by the operator to the user interface;
