Abstract

A method includes receiving first information indicative of a location of a perimeter of a worksite surface, and receiving second information indicative of compaction requirements specific to the worksite surface. The method also includes generating a compaction plan based at least partly on the first and second information. Such a compaction plan includes a travel path for a compaction machine. In such a method, the travel path is substantially within the perimeter of the worksite surface. The method also includes causing at least part of the travel path to be displayed via a control interface of the compaction machine. The method further includes receiving an input indicative of approval of the travel path, and controlling operation of the compaction machine on the worksite surface, in accordance with the compaction plan, based at least partly on receiving the input.

First claim

What is claimed is:

1. A method, comprising:
receiving, with one or more processors, first information indicative of a perimeter of a worksite surface, the worksite surface being disposed at a worksite;
receiving, with the one or more processors, second information indicative of requirements specific to the worksite surface;
generating, with the one or more processors, a plan based at least partly on the first information and the second information, the plan indicating:
a travel path of a machine at the worksite, wherein the travel path is substantially within the perimeter of the worksite surface, and
one or more operations to be performed by the machine at the worksite as the machine traverses the travel path; and

causing, with the one or more processors, the machine to perform the one or more operations on the worksite surface, in accordance with the plan, and along the travel path.

2. The method of claim 1 , further including:
receiving, with the one or more processors, third information indicative of a property of a portion of the worksite surface located along the travel path; and
adjusting the one or more operations as the machine traverses the travel path, based at least partly on the third information.

3. The method of claim 1 , wherein the machine is a compaction machine.

4. The method of claim 3 , further comprising:
receiving third information indicative of a property of a portion of the worksite surface located along the travel path; and
adjusting the one or more operations as the machine traverses the travel path, based at least partly on the third information,
wherein adjusting the one or more operations includes adjusting at least one of a vibration frequency of a drum connected to the machine or a vibration amplitude of the drum.

5. The method of claim 1 , further comprising:
causing at least part of the travel path to be displayed; and
receiving an input indicating approval of the travel path,
wherein causing the machine to perform the one or more operations on the worksite surface is based at least partly on receiving the input.

6. The method of claim 5 , wherein:
the at least part of the travel path is displayed via a control interface of the machine; and
the input is received via the control interface of the machine.

7. The method of claim 1 , wherein the one or more processors are disposed at a location remote from the machine.

8. A method, comprising:
receiving, with one or more processors, first information indicative of a perimeter of a worksite surface, the worksite surface being disposed at a worksite;
receiving, with the one or more processors, second information indicative of compaction requirements specific to the worksite surface;
generating, with the one or more processors, a compaction plan based at least partly on the first information and the second information, the compaction plan indicting:
a travel path of a compaction machine at the worksite, wherein the travel path is substantially within the perimeter of the worksite surface, and
one or more operations to be performed by the compaction machine at the worksite as the compaction machine traverses the travel path; and

causing at least part of the travel path to be displayed on a device associated with the machine;
receiving, from the device, an input indicating an acceptance of the compaction plan;
causing, with the one or more processors and based at least in part on receiving the input, the compaction machine to perform the one or more operations on the worksite surface, in accordance with the compaction plan.

9. The method of claim 8 , further comprising:
causing at least part of the travel path to be displayed; and
receiving an input indicating approval of the travel path,
wherein causing the compaction machine to perform the one or more operations on the worksite surface is based at least partly on receiving the input.

10. The method of claim 9 , wherein:
the at least part of the travel path is displayed via a control interface of the compaction machine; and
the input is received via the control interface of the compaction machine.

11. The method of claim 8 , wherein the one or more processors are disposed at a location remote from the compaction machine.

12. The method of claim 8 , further comprising:
receiving, with the one or more processors, third information indicative of a property of a portion of the worksite surface located along the travel path; and
adjusting the one or more operations as the compaction machine traverses the travel path, based at least partly on the third information.

13. The method of claim 12 , wherein adjusting the one or more operations includes adjusting compaction operation of a drum of the compaction machine relative to the worksite surface.

14. A control system, comprising:
a control interface connected to a machine at a worksite; and
one or more processors remote from the machine and in communication with the control interface, the one or more processors configured to:
receive first information indicative of a perimeter of a worksite surface at the worksite,
receive second information indicative of requirements specific to the worksite surface,
determining a travel path of the machine, wherein the travel path is substantially within the perimeter of the worksite surface,
generate, based at least partly on the first information, the second information, and the travel path, a plan indicating one or more operations to be performed by the machine as the machine traverses the travel path, and
cause the machine to perform the one or more operations on the worksite surface, in accordance with the plan.

15. The control system of claim 14 , wherein the one or more processors are further configured to:
receive third information indicative of a property of a portion of the worksite surface located along the travel path; and
adjust the one or more operations as the machine traverses the travel path, based at least partly on the third information.

16. The control system of claim 15 , wherein the machine is a compaction machine.

17. The control system of claim 16 , wherein adjusting the one or more operations includes adjusting at least one of a vibration frequency of a drum connected to the machine and a vibration amplitude of the drum.

18. The control system of claim 17 , wherein the the one or more processors are further configured to:
cause at least part of the travel path to be displayed; and
receive an input indicating approval of the travel path,
wherein causing the machine to perform the one or more operations on the worksite surface is based at least partly on receiving the input.

19. The control system of claim 18 , wherein:
the at least part of the travel path is displayed via a control interface of the machine; and
the input is received via the control interface of the machine.

20. The control system of claim 14 , wherein the one or more processors are further configured to:
cause at least part of the travel path to be displayed; and
receive an input indicative of approval of the travel path,
wherein causing the machine to perform the one or more operations on the worksite surface is based at least partly on receiving the input.
