Abstract

A system for surface data management for a machine is provided. A first controller maintains an updated surface data and an updating time. A second controller maintains a surface data and a recording time. The second controller transmits a time request for the updating time associated with a destination location. The second controller receives the updating time associated with the destination location. The second controller is compares the updating time with the recording time, each associated with the destination location. If the updating time is more recent than the recording time, the second controller transmits a data request for the updated surface data associated with the destination location and receives the updated surface data. The second controller compares the updated surface data with the surface data, each associated with the destination location and determines a change in the surface data associated with the destination location based on the comparison.

Claims

1. A system for surface data management for a machine operating on a worksite, the system comprising:

a first controller located off-board the machine, the first controller configured to maintain an updated surface data associated with the worksite and an updating time associated with the updated surface data; and

a second controller located on-board the machine, the second controller communicably coupled to the first controller, the second controller configured to;

maintain a surface data associated with the worksite and a recording time associated with the surface data;

transmit a time request for the updating time associated with a destination location on the worksite;

receive the updating time associated with the destination location;

compare the updating time with the recording time, each associated with the destination location;

transmit a data request for the updated surface data associated with the destination location, if the updating time is more recent than the recording time;

receive the updated surface data associated with the destination location;

compare the updated surface data with the surface data, each associated with the destination location; and

determine a change in the surface data associated with the destination location based on the comparison of the updated surface data with the surface data.

2. The system of claim 1, wherein the second controller is further configured to:

adjust one or more parameters of the machine based on the determination.

3. The system of claim 2, wherein the one or more parameters include at least one of a speed of the machine, a direction of travel of the machine, and a power output of the machine.

4. The system of claim 1, wherein the second controller is configured to:

transmit the data request for the updated surface data associated with the destination location from a pre-determined time;

receive the updated surface data associated with the destination location;

compare the updated surface data with the surface data, each associated with the destination location; and

determine the change in the surface data associated with the destination location based on the comparison of the updated surface data with the surface data.

5. The system of claim 1, wherein the second controller is further configured to:

update the surface data and the recording time associated with the destination location on the worksite based on the determination.

6. The system of claim 1, wherein the destination location includes a position information associated with the destination location on the worksite, the position information including at least one of a co-ordinate associated with the destination location and an area on the worksite.

7. The system of claim 6, wherein the destination location includes a resolution information based on a degree of specificity required for the destination location.

8. The system of claim 1, wherein the second controller is further configured to:

determine the destination location on the worksite based on a scheduled task to be performed by the machine.

9. The system of claim 1, wherein the first controller is located at a remote control station.

10. The system of claim 1, wherein the machine is an autonomous machine.

11. A method for surface data management for a machine operating on a worksite, the method being performed by a microprocessor, the method comprising:

maintaining a surface data associated with the worksite and a recording time associated with the surface data;

transmitting a time request for an updating time associated with a destination location on the worksite;

receiving the updating time associated with the destination location;

comparing the updating time with the recording time, each associated with the destination location;

transmitting a data request for an updated surface data associated with the destination location, if the updating time is more recent than the recording time;

receiving the updated surface data associated with the destination location;

comparing the updated surface data with the surface data, each associated with the destination location; and

determining a change in the surface data associated with the destination location based on the comparison of the updated surface data with the surface data.

12. The method of claim 11 further comprising:

adjusting one or more parameters of the machine based on the determination.

13. The method of claim 12, wherein the one or more parameters include at least one of a speed of the machine, a direction of travel of the machine, and a power output of the machine.

14. The method of claim 11 further comprising:

transmitting the data request for the updated surface data associated with the destination location from a pre-determined time;

receiving the updated surface data associated with the destination location;

comparing the updated surface data with the surface data, each associated with the destination location; and

determining the change in the surface data associated with the destination location based on the comparison of the updated surface data with the surface data.

15. The method of claim 11 further comprising:

updating the surface data and the recording time associated with the destination location on the worksite based on the determination.

16. The method of claim 11 further comprising:

determining the destination location on the worksite based on a scheduled task to be performed by the machine.

17. A machine operating on a worksite, the machine comprising:

a controller located on-board the machine, the controller configured to;

maintain a surface data associated with the worksite and a recording time associated with the surface data;

transmit a time request for an updating time associated with a destination location on the worksite;

receive the updating time associated with the destination location;

compare the updating time with the recording time, each associated with the destination location;

transmit a data request for an updated surface data associated with the destination location, if the updating time is more recent than the recording time;

receive the updated surface data associated with the destination location on the worksite;

compare the updated surface data with the surface data, each associated with the destination location;

determine a change in the surface data associated with the destination location based on the comparison of the updated surface data with the surface data; and

adjust one or more parameters of the machine based on the determination.

18. The machine of claim 17, wherein the one or more parameters include at least one of a speed of the machine, a direction of travel of the machine, and a power output of the machine.

19. The machine of claim 17, wherein the destination location includes a position information associated with the destination location on the worksite, the position information including at least one of a co-ordinate associated with the destination location and an area on the worksite.

20. The machine of claim 19, wherein the destination location includes a resolution information based on a degree of specificity required for the destination location.
