Abstract

A mining machine comprising a power monitor sensing power consumption of the mining machine during a select time period to generate power consumption data; a sensor sensing payload of the mining machine during the select time period to generate payload data; and a monitoring module. The monitoring module including computer readable media for comparing the power consumption data and the payload data to generate shovel efficiency data, and outputting the shovel efficiency data.

Claims

1. A mining machine comprising:

a power monitor sensing power consumption of the mining machine during a select time period to generate power consumption data;

a sensor sensing payload of the mining machine during the select time period to generate payload data; and

a monitoring module including computer readable media for

comparing the power consumption data and the payload data to generate shovel efficiency data, and

outputting the shovel efficiency data.

2. The mining machine of claim 1, further comprising a user-interface that indicates the shovel efficiency data.

3. The mining machine of claim 1, further including a network for communicating the shovel efficiency data.

4. The mining machine of claim 3, wherein the shovel efficiency data is displayed at a remote location.

5. The mining machine of claim 1, wherein the power monitor senses power consumption of the mining shovel during further time periods to generate further power consumption data, the sensor senses payload of the mining shovel during the further time periods to generate further payload data, and the monitoring module compares the further power consumption data and further payload data to generate further shovel efficiency data.

6. The mining machine of claim 1, wherein the select time period and shovel efficiency data are associated with a particular mining machine operation cycle.

7. A method for monitoring a mining machine, the method comprising:

receiving data from the mining machine, the data including

power consumption data of the mining machine, and

payload data of the mining machine;

comparing the power consumption data and the payload data to generate shovel efficiency data; and

outputting the shovel efficiency data.

8. The method of claim 7, further comprising

receiving data from a second mining machine, the data including

second power consumption data of the second mining machine, and

second payload data of the second mining machine;

comparing the second power consumption data and the second payload data to generate second shovel efficiency data;

outputting the second shovel efficiency data.

9. The method of claim 7, wherein the step of comparing the power consumption data and the payload data is performed by a monitoring module on the mining machine.

10. The method of claim 7, wherein the steps of comparing are performed by a monitoring module remote from the mining machine.

11. The method of claim 7, further comprising displaying the shovel efficiency data on a display remote from the mining machine.

12. The method of claim 7, further comprising displaying the shovel efficiency data on a user-interface of the mining machine.

13. The method of claim 7, wherein a select time period and the shovel efficiency data are associated with a particular mining machine operation cycle.

14. A monitoring module for monitoring a mining machine, the monitoring module comprising:

a memory including a program storage area and a data storage area, the program storage area and the data storage area including at least one of a read-only memory, a random access memory, a flash memory, and a hard disk; and

a processor executing instructions stored on the memory, the instructions including

receiving power consumption data from the mining machine,

receiving payload data from the mining machine,

comparing the power consumption data and the payload data to generate shovel efficiency data, and

outputting the shovel efficiency data.

15. The monitoring module of claim 14, further coupled to a user-interface of the mining machine that receives and indicates the shovel efficiency data.

16. The monitoring module of claim 14, further coupled to a network for communicating the shovel efficiency data to a remote device.

17. The monitoring module of claim 16, wherein the shovel efficiency data is displayed on the remote device.

18. The monitoring module of claim 14, wherein a select time period and the shovel efficiency data are associated with a particular mining machine operation cycle.
