Monitoring ground-engaging products for earth working equipment

1. A monitoring system comprising:

a ground-engaging product secured to earth working equipment at a worksite, the ground-engaging product including an exterior surface and an opening, and

a monitoring device secured in the opening and including an electronic device to monitor at least one characteristic of the ground-engaging product, and a communication device to wirelessly transmit data gathered by the electronic device;

at least one remote device to wirelessly receive the data; and

at least one programmable logic device to process the data to determine at least one characteristic associated with ground being worked by the earth working machine.

2. The monitoring system of claim 1 wherein the worksite is a mine.

3. The monitoring system of claim 1 wherein the at least one programmable logic device uses the transmitted data to determine the at least one characteristic at a plurality of locations at the worksite.

4. The monitoring system of claim 1 wherein the at least one characteristic includes the wear rate for the ground-engaging product on account of working the ground at the worksite.

5. The monitoring system of claim 4 wherein the at least one programmable logic device uses the at least one characteristic to determine a replacement schedule for the ground-engaging product.

6. The monitoring system of claim 1 wherein the at least one characteristic includes the penetrability of the ground at the worksite.

7. The monitoring system of claim 1 wherein the at least one programmable logic device determines the digging rate of the earth working machine.

8. The monitoring system of claim 1 wherein the at least one remote device determines timetables for excavating material.

9. The monitoring system of claim 1 including at least one database including worksite information, wherein the at least one programmable logic device uses the worksite information to determine the at least one characteristic.
