Abstract

System and methods for managing operations of one or more machines are disclosed. One method includes receiving first information relating to an operation of a dump body of a hauling machine operating in at least a partially autonomous manner, determining a failure condition of the operation based at least on the received first information, transmitting a notification relating to the failure condition, and causing a boost pressure to be applied to the dump body of the hauling machine.

First claim

We claim:

1. A method comprising:
sensing first information relating to an operation of a dump body of a hauling machine, the hauling machine operating in at least a partially autonomous manner;
receiving, by one or more processors, the first information, wherein the first information comprises an operational state of the hauling machine;
determining, by the one or more processors, a failure condition of the operation based at least on the received first information;
transmitting a notification relating to the failure condition from the one or more processors to a worksite controller, wherein the notification comprises an indication that a dump site is full; and
causing a boost pressure to be applied to the dump body of the hauling machine.

2. The method of claim 1 , wherein the operational state of hauling machine comprises one or more of a lift position of the dump body and a pressure applied to the dump body by an actuator of the hauling machine.

3. The method of claim 1 , wherein the determining the failure condition further comprises one or more of comparing the first information to a threshold comparator and determining an irregularity in operation based on predetermined operational parameters.

4. The method of claim 1 , wherein the failure condition further comprises one or more of a failed raising of the dump body and a failed lowering of the dump body.

5. The method of claim 1 , wherein the causing the boost pressure to be applied to the dump body comprises increasing a lowering force applied to the dump body.

6. The method of claim 1 , further comprising receiving second information relating to the operation of the dump body of the hauling machine in response to the applied boost pressure.

7. The method of claim 1 , further including receiving location information relating to the dump site.

8. A system comprising:
a sensor configured to sense first information relating to an operation of a dump body of a hauling machine, the hauling machine operating in at least a partially autonomous manner;
a processor; and
a memory bearing instructions that, upon execution by the processor, cause the system at least to:
receive the first information;
determine a failure condition of the operation based at least on the received first information;
transmit a notification relating to the failure condition to a worksite controller; and
cause a boost pressure to be applied to the dump body of the hauling machine, the applied boost pressure increasing a lowering force applied to the dump body.

9. The system of claim 8 , wherein the first information comprises one or more of a lift position of the dump body and a pressure applied to the dump body by an actuator of the hauling machine.

10. The system of claim 8 , wherein the determining the failure condition comprises one or more of comparing the first information to a threshold comparator and determining an irregularity in operation based on predetermined operational parameters.

11. The system of claim 8 , wherein the failure condition comprises one or more of a failed raising of the dump body and a failed lowering of the dump body.

12. The system of claim 8 , further including receiving additional information including location information relating to a dump site, and wherein the notification comprises an indication that the dump site is full.

13. The system of claim 8 , further comprising receiving second information relating to the operation of the dump body of the hauling machine in response to the applied boost pressure.

14. A computer-implemented method comprising:
sensing first information relating to an operation of a dump body of a machine, the first information including an operational state of the machine;
receiving, by one or more processors, the first information;
determining, by the one or more processors, a failure condition of the operation based at least on the received first information;
generating a response signal based at least on the determined failure condition, wherein the response signal comprises one or more of a notification of the failure condition from the one or more processors to a worksite controller, and a remediation to the failure condition, wherein the notification comprises an indication that a dump site is full.

15. The method of claim 14 , wherein the machine is operating in at least a partially autonomous manner.

16. The method of claim 14 , wherein the machine is a hauling machine.

17. The method of claim 14 , wherein the remediation to the failure condition comprises one or more of closing the dump site and autonomously causing a change in the operational state of the machine.

18. The computer-implemented method of claim 14 , further including receiving information relating to a machine type, and receiving information relating to a location of the dump site.

19. The computer-implemented method of claim 14 , further including receiving an instruction from the worksite controller to relocate the machine from the dump site.

20. The computer-implemented method of claim 14 , wherein the operational state of the machine comprises one or more of a lift position of the dump body and a pressure applied to the dump body by an actuator of the machine.
