Abstract

A ground marking system includes a position signal receiver configured to receive a position signal and generate current position information based on the position signal. A paint supply is configured to discharge paint onto ground beneath the paint supply. A first actuator is operatively connected to the paint supply for linearly moving the paint supply in both a first direction and a second direction opposite the first direction. A second actuator is operatively connected to the paint supply for controlling the discharge of paint from the paint supply. A memory device stores predetermined positional data. A processor is in communication with the position signal receiver and the memory device, and is configured to control linear movements of the first actuator based on the current position information received from the position signal receiver and the predetermined positional data stored in the memory device, and adjust a position of the paint supply.

Claims

1. A ground marking system, comprising:

a position signal receiver configured to receive a position signal and generate current position information based on the position signal;

a paint supply configured to discharge paint onto ground beneath the paint supply;

a first actuator operatively connected to the paint supply for linearly moving the paint supply in both of a first direction and a second direction opposite the first direction;

a second actuator operatively connected to the paint supply for controlling the discharge of paint from the paint supply;

a memory device storing predetermined positional data; and

a processor in communication with the position signal receiver and the memory device, wherein the processor is configured to control linear movements of the first actuator based on the current position information received from the position signal receiver and the predetermined positional data stored in the memory device and thereby adjust a position of the paint supply,

wherein;

the ground marking system is mounted to a vehicle,

the first actuator comprises a double acting hydraulic cylinder having an extensible and retractable rod, and the first actuator comprises a valve for controlling operations of the double acting hydraulic cylinder,

the processor is operatively connected to the valve to control operations of the valve based on the current position information received from the position signal receiver and the predetermined positional data stored in the memory device, and

the ground marking system further comprises a movable frame that is attached to the rod of the actuator and that includes a paint supply holder for mounting the paint supply such that the movable frame moves with the paint supply in both of the first direction and the second direction.

2. The ground marking system of claim 1, wherein the position signal receiver is connected to the paint supply and the first actuator such that the position signal receiver moves with the paint supply in both of the first direction and the second direction.

3. The ground marking system of claim 1, wherein the predetermined positional data is included in a CAD file stored in the memory device.

4. The ground marking system of claim 3, further comprising a display device operatively connected to the processor for displaying the CAD file;

and

a user interface operatively connected to the processor and configured for allowing a user to select the predetermined positional data from the displayed CAD file.

5. The ground marking system of claim 4, wherein the processor is configured to control operations of the valve based on the current position information received from the position signal receiver, the predetermined positional data stored in the memory device, and an offset distance, relative to the predetermined positional data, entered via the user interface.

6. The ground marking system of claim 1, wherein the second actuator comprises a solenoid configured to control the discharge of paint from the paint supply, the system further comprising a switch located within an operator compartment of the vehicle for controlling operations of the solenoid.

7. The ground marking system of claim 1, wherein the position signal receiver is a global navigation satellite system (GNSS) receiver.

8. The ground marking system of claim 1, wherein the movable frame includes a skid mounted between the paint supply and the ground beneath the paint supply, the skid forming a paint aperture through which paint is discharged onto the ground beneath the skid.

9. The ground marking system of claim 1, further comprising:

a fixed frame, and

a linearly-movable support bar extending between the fixed frame and the movable frame, wherein the linearly-movable support bar moves linearly within the fixed frame and substantially parallel with the rod of the double acting hydraulic cylinder.

10. The ground marking system of claim 9, further comprising a second hydraulic cylinder configured for selectively raising and lowering together each of the fixed frame, the movable frame, the double acting hydraulic cylinder and the linearly-movable support bar.

11. A ground marking system, comprising:

a position signal receiver configured to receive a position signal and generate current position information based on the position signal;
