Abstract

A system and tool for monitoring ground-engaging products for earth working equipment that can monitor characteristics such as part identification, presence, condition, usage, and/or performance of the products on earth working equipment used, for example, in mining, construction, and dredging environments. The monitoring tool includes or is supported by a mobile device that is separate from the earth working equipment. Supporting the monitoring tool on a mobile device can, e.g., provide unique vantage points to monitor the earth working equipment products, monitor the products without inhibiting the operation of the earth working equipment or endangering personnel, closely approach areas of interest for secure and reliable gathering of information, monitor multiple earth working equipment, and/or be protected from the vibrations and impact shocks that can be associated with earth working equipment.

First claim

The invention claimed is:

1. A monitoring system comprising:
an excavating machine including a bucket having a plurality of wear parts; and
a monitoring tool separate from the excavating machine, wherein the monitoring tool includes an unmanned aerial vehicle that is movable independently of the excavating machine to different locations relative to the excavating machine, and an electronic surface characterization sensor secured to the vehicle to detect the absence of the wear parts on the bucket and/or the condition of the bucket and/or the wear parts.

2. A monitoring system in accordance with claim 1 wherein the surface characterization device is an optical camera.

3. A monitoring system in accordance with claim 1 wherein the surface characterization device creates a point cloud representation of at least one portion of the bucket and/or the wear parts.

4. A monitoring system in accordance with claim 1 including a processor to receive information detected by the sensor and determine the condition of the bucket and/or the wear parts and/or whether the wear parts have separated from the bucket.

5. The monitoring system of claim 1 , wherein the vehicle is autonomous.

6. The monitoring system of claim 1 , wherein the unmanned aerial vehicle includes a processor that calculates a protected zone around the excavating machine to control a flight pattern of the unmanned aerial vehicle so the unmanned aerial vehicle does not enter the protected zone.

7. The monitoring system of claim 1 , further comprising a position sensor located on the excavating machine, and wherein the unmanned aerial vehicle includes a processor configured to receive position information from the position sensor and to control a flight pattern of the unmanned aerial vehicle based at least in part on the position information.

8. The monitoring system of claim 1 , further comprising a remote electronic device separate from the earth working equipment and wherein the remote electronic device is configured to receive the characteristic determined by the electronic sensor, retrieve information from a database, and compare the characteristic to the information.

9. The monitoring system of claim 8 , wherein the information includes a wear profile.

10. The monitoring system of claim 1 , wherein the monitoring tool includes a maneuvering device for maneuvering the sensor to point the sensor in a desired direction without additional maneuvering of the vehicle.

11. The monitoring system of claim 1 , wherein the monitoring tool includes an obstacle avoidance system operable to avoid contacting the excavating machine.

12. The monitoring system of claim 11 , wherein the excavating machine includes a device that communicates position information to the monitoring tool to aid the obstacle avoidance system.

13. The monitoring system of claim 1 , wherein the sensor captures positions of components of the excavating machine.

14. The monitoring system of claim 1 , wherein the sensor detects loads gathered in the bucket during use of the excavating machine.

15. The monitoring system of claim 1 , wherein the monitoring tool includes a communicating device for receiving information from a remote device and/or transmitting information detected by the sensor.
