Abstract

A haul-route management system is provided. The system includes a first sensor module configured to generate a signal indicative of a current position of a machine at the worksite. The system also includes a route control module configured to receive the signal indicative of the current position of the machine. The route control module receives a signal indicative of a predetermined path associated with the machine. The route control module segments a current path of the machine based on predetermined boundaries. Further, the route control module compares the segmented current path with corresponding data points on the predetermined path. The route control module determines if a deviation from the predetermined path is present in at least one portion of the current path based on the comparison. The route control module provides a notification of the deviation if the deviation lies outside of a predetermined range.

Claims

1. A haul-route management system for a machine operating at a worksite, the system comprising:

a first sensor module configured to generate a signal indicative of a current position of the machine at the worksite; and

a route control module communicably coupled to the first sensor module, the route control module configured to;

receive the signal indicative of the current position of the machine;

receive a signal indicative of a predetermined path associated with the machine on at least one of a per cycle and a material basis;

segment a current path of the machine based, at least in part, on predetermined boundaries;

compare the segmented current path with corresponding data points on the predetermined path;

determine if a deviation from the predetermined path is present in at least one portion of the current path based on the comparison; and

provide a notification of the deviation if the deviation lies outside of a predetermined range.

2. The system of claim 1, wherein the first sensor module is at least one of a global positioning system, an accelerometer, and a gyroscope.

3. The system of claim 1, wherein the route control module is further configured to receive a signal indicative of at least one of a speed and a heading of the machine.

4. The system of claim 1, wherein the route control module is further configured to control an operation of the machine if the deviation is present.

5. The system of claim 1, wherein the route control module is further configured to receive the predetermined path via an input device, wherein the predetermined path is at least one of provided by a user and selected from a set of established routes.

6. The system of claim 1, wherein the route control module is further configured to assign any one of a load and a dump location to the machine via the input device.

7. The system of claim 1, wherein the route control module is further configured to estimate the predetermined path based, at least in part, on a previous path of the machine and an average path taken by a fleet of the machines.

8. The system of claim 1, wherein the route control module is further configured to:

cluster the segmented current path until the segmented current path matches with the predetermined path if the deviation is present; and

identify the at least one portion of the segmented current path that deviates from the predetermined path based on the clustering.

9. The system of claim 1, wherein the route control module is configured to compute an average path of corresponding current positions of the current path and the data points of the predetermined path if the deviation is ab sent.

10. The system of claim 1, wherein the route control module is further configured to provide a notification of a change in the predetermined path.

11. The system of claim 1, wherein the predetermined range is input by a user.

12. A method for haul route management for a machine operating at a worksite, the method comprising:

receiving a signal indicative of a current position of the machine at the worksite;

receiving a signal indicative of a predetermined path associated with the machine on at least one of a per cycle and a material basis;

segmenting a current path of the machine based, at least in part, on predetermined boundaries;

comparing the segmented current path with corresponding data points on the predetermined path;

determining if a deviation from the predetermined path is present in at least one portion of the current path based on the comparison; and

providing a notification of the presence of the deviation if the deviation lies outside of a predetermined range.

13. The method of claim 12 further including:

receiving a signal indicative of at least one of a speed and a heading of the machine.

14. The method of claim 12 further including:

controlling an operation of the machine if the deviation is present.

15. The method of claim 12 further including:

receiving the predetermined path via an input device, wherein the predetermined path is at least one of provided by a user and selected from a set of established routes.

16. The method of claim 12 further including:

assigning any one of a load and a dump location to the machine via the input device.

17. The method of claim 12 further including:

estimating the predetermined path based, at least in part, on a previous path of the machine and an average path taken by a fleet of the machines.

18. The method of claim 12 further including:

clustering segmented current path until the segmented current path matches with the predetermined path if the deviation is present; and

identifying the at least one portion of the segmented current path that deviates from the predetermined path based on the clustering.

19. The method of claim 12 further including:

computing an average path of corresponding current positions of the current path and the data points of the predetermined path if the deviation is absent.

20. The method of claim 12 further including:

providing a notification of a change in the predetermined path.
