Abstract

Methods for decomposing event information for a machine are described. In one aspect, a method includes receiving event data identifying events associated with a machine on a first communications channel, and receiving trend data for the machine associated with the identified events on a second communications channel separate from the first communications channel. Systems and machine-readable media are also described.

Claims

1. A method for decomposing event information for a mining machine comprising:

receiving event data identifying events comprising warnings, faults and state messages associated with the mining machine on a first communications channel via a network, the event data being received from the mining machine and the mining machine being positioned at a remote location; and

receiving trend data for the mining machine on a second communications channel separate from the first communications channel via the network, the trend data being associated with the warnings, the faults and the state messages and being received from the mining machine positioned at the remote location.

2. The method of claim 1, wherein the trend data comprises time series data for measurement information.

3. The method of claim 2, wherein the measurement information comprises at least one of temperature information and voltage information.

4. The method of claim 1, wherein the warnings, the faults, and the state messages are generated on the mining machine as trend data is analyzed on the mining machine.

5. The method of claim 1, further comprising the step of identifying the warnings, the faults and the state messages by a state machine executed onboard the mining machine.

6. The method of claim 5, wherein identifying the warnings, the faults and the state messages is executed in real time on the mining machine.

7. The method of claim 1, wherein the trend data is received separately from the event data.

8. The method of claim 1, wherein the warnings, the faults and the state messages identified in the event data can be matched with associated trend data.

9. The method of claim 1, wherein the trend data is received synchronously with the warnings, the faults and the state messages.

10. The method of claim 9, wherein receiving the trend data synchronously with the warnings, the faults and the state messages comprises receiving data for an event identified in the event data at about the same time as trend data for the event.

11. The method of claim 1, wherein the mining machine is at least one of a mining drill, mining conveyor, dragline, mining shovel, surface mining machine, underground mining machine, mining haulage vehicle and mobile mining crusher.

12. The method of claim 1, further comprising identifying an episode, wherein the episode is identified by a plurality of events occurring within a particular period of time.

13. The method of claim 12, wherein the episode is identified as beginning when a first fault is identified, and ending when the mining machine is determined to start in a normal mode or a no communications message is issued.

14. A system for predicting a machine event for a mining machine comprising:

a memory comprising instructions; and

a processor configured to execute the instructions to;

receive event data identifying events comprising warnings, faults and state messages associated with a mining machine on a first communications channel via a network, the event data being received from the mining machine and the mining machine being positioned at a remote location; and

receive trend data for the mining machine associated with the warnings, the faults and the state messages on a second communications channel separate from the first communications channel via the network, the trend data being received from the mining machine positioned at the remote location.

15. The system of claim 14, wherein the trend data comprises time series data for measurement information.

16. The system of claim 15, wherein the measurement information comprises at least one of temperature information and voltage information.

17. The system of claim 14, wherein the warnings, the faults and the state messages are generated on the mining machine as trend data is analyzed on the mining machine.

18. The system of claim 14, further comprising the step of identifying the warnings, the faults and the state messages by a state machine executed onboard the mining machine.

19. The system of claim 18, wherein identifying the warnings, the faults and the state messages is executed in real time on the mining machine.

20. The system of claim 14, wherein the trend data is received separately from the event data.

21. The system of claim 14, wherein the warnings, the faults and the state messages identified in the event data can be matched with associated trend data.

22. The system of claim 14, wherein the trend data is received synchronously with the event data.

23. The system of claim 22, wherein receiving the trend data synchronously with the event data comprises receiving data for an event identified in the event data at about the same time as trend data for the event.

24. The system of claim 14, wherein the mining machine is at least one of a mining drill, mining conveyor, dragline, mining shovel, surface mining machine, underground mining machine, mining haulage vehicle and mobile mining crusher.

25. The system of claim 14, further comprising identifying an episode, wherein the episode is identified by a plurality of events occurring within a particular period of time.

26. The system of claim 25, wherein the episode is identified as beginning when a first fault is identified, and ending when the mining machine is determined to start in a normal mode or a no communications message is issued.

27. The system of claim 14, further comprising identifying an episode, wherein the episode is an accumulation of events that begin with a mining machine shutdown and end when the mining machine successfully restarts for greater than a predetermined time.

28. A non-transitory machine-readable storage medium comprising machine-readable instructions for causing a processor to execute a method for decomposing event information for a mining machine, comprising:

receiving event data identifying events comprising warnings, faults and state messages associated with the mining machine on a first communications channel via a network, the event data being received from the mining machine and the mining machine being positioned at a remote location; and

receiving trend data for the mining machine associated with the warnings, the faults and the state messages on a second communications channel separate from the first communications channel via the network, the trend data being associated with the warnings, the faults and the state messages and being received from the mining machine positioned at the remote location.

29. The storage medium of claim 28, further comprising identifying an episode, wherein the episode is identified by a plurality of events occurring within a particular period of time.

30. The storage medium of claim 29, wherein the episode is identified as beginning when a first fault is identified, and ending when the mining machine is determined to start in a normal mode or a no communications message is issued.
