Abstract

Systems and methods for training an operator. One system includes a computing device including a processing unit and computer-readable medium. The computer-readable medium stores a training simulator application. The training simulator application, when executed by the processing unit, is configured to (i) receive an operating command from the operator, (ii) generate a simulated working environment and a simulated shovel having a simulated dipper, the simulated shovel and the simulated dipper positioned within the simulated working environment based on the operating command, (iii) generate an indicator providing depth-related information to an operator relating to a position of the simulated dipper with respect to a point-of-reference within the simulated working environment, and (iv) output the simulated working environment and the indicator to at least one output device for display to the operator.

Claims

1. A method for training an operator of a shovel, the method comprising:

generating, with a processor, a simulated training environment including a ground plane and a simulated shovel having a simulated dipper;

displaying an indicator within the simulated training environment marking at least a portion of a low-grade plane within the ground plane;

determining a current position of the low-grade plane;

determining a current position of the simulated dipper with respect to the low-grade plane;

determining if at least a portion of the simulated dipper is below the low-grade plane based on the current position of the simulated dipper within the simulated training environment and the current position of the at least a portion of the low-grade plane; and

when at least a portion of the simulated dipper is below the low-grade plane, providing at least one warning to an operator of the simulated shovel, wherein providing the at least one warning to the operator includes modifying the indicator.

2. The method of claim 1, wherein displaying the indicator of the low-grade plane includes highlighting at least a portion of the low-grade plane in a first color different than a second color of the ground plane.

3. The method of claim 2, wherein providing the at least one warning to the operator includes modifying the first color of the indicator to a third color.

4. The method of claim 2, wherein providing the at least one warning to the operator includes fading the first color of the indicator from the first color to a third color.

5. The method of claim 1, wherein providing the at least one warning to the operator includes changing at least one of color, size, shape, pattern, and animation of the indicator.

6. The method of claim 1, wherein providing the at least one warning to the operator includes providing a text-based warning to the operator within the simulated training environment.

7. The method of claim 1, wherein providing the at least one warning to the operator includes providing at least one of an audible warning and a tactile warning to the operator.

8. The method of claim 1, wherein displaying the indicator includes highlighting a portion of the ground plane adjacent a simulated bank.

9. The method of claim 1, further comprising:

generating a simulated haul truck within the simulated training environment;

determining a swing path of the simulated dipper;

determining a centerline of a bed of the simulated haul truck;

displaying a graphical representation of the centerline on the simulated haul truck;

displaying a second indicator within the simulated training environment of at least a portion of the swing path of the simulated dipper;

determining a current position of the simulated dipper with respect to the centerline;

determining a current position of the centerline;

determining if the simulated dipper is positioned within a predetermined distance from the centerline; and

alerting the operator when the simulated dipper is positioned within the predetermined distance from the centerline, wherein alerting the operator includes modifying the second indicator.

10. The method of claim 9, wherein displaying the second indicator includes displaying the second indicator in a color.

11. The method of claim 10, wherein alerting the operator includes modifying the first color of the second indicator to a second color.

12. The method of claim 9, wherein alerting the operator includes modifying at least one of color, size, shape, pattern, and animation of the second indicator.

13. The method of claim 9, wherein alerting the operator including changing at least a portion of the simulated shovel.

14. The method of claim 13, wherein changing at least a portion of the simulated shovel includes changing a color of the simulated dipper to a color of the second indicator.

15. The method of claim 9, wherein alerting the operator includes providing a text-based message to the operator within the simulated training environment.

16. The method of claim 9, wherein alerting the operator includes providing at least one of audible feedback and tactile feedback to the operator.

17. The method of claim 9, wherein alerting the operator includes changing a color of the graphical representation of the centerline.

18. The method of claim 9, wherein the second indicator includes a circular outline.

19. A system for training an operator, the system comprising:

a computing device including a processing unit and computer-readable medium, the computer-readable medium storing a training simulator application;

wherein the training simulator application, when executed by the processing unit, is configured to

generate a simulated training environment including a ground plane and a simulated shovel having a simulated dipper,

display an indicator within the simulated training environment marking at least a portion of a low-grade plane within the ground plane,

determine a current position of the low-grade plane,

determine a current position of the simulated dipper with respect to the low-grade plane,

determine if at least a portion of the simulated dipper is below the low-grade plane based on the current position of the simulated dipper within the simulated training environment and the current position of the at least a portion of the low-grade plane, and

when at least a portion of the simulated dipper is below the low-grade plane, providing at least one warning to an operator of the simulated shovel, wherein providing the at least one warning to the operator includes modifying the indicator.

20. The system of claim 19, wherein the training simulator application is configured to modify the indicator by modifying a color of the indicator.

21. The system of claim 19, wherein the training simulator application is further configured to generate a second indicator that marks at least a portion of a swing path of the simulated dipper.

22. The system of claim 21, wherein the training simulator application is further configured to modify the second indicator when the current position of the simulated dipper is aligned with a current position of a centerline of a simulated haul truck.
