Abstract

A payload monitoring system on a machine includes a payload sensor configured to generate a plurality of payload data corresponding to a payload amount in a bucket of a machine, the plurality including a first payload data and a second payload data and a controller. The controller is configured to receive the first payload data from the payload sensor and off-board payload data from an off-board system, compare the first payload data to the off-board payload data to generate a payload data offset, receive the second payload data from the payload sensor, and generate an adjusted payload data based on the second payload data and the payload data offset.

Claims

1. A payload monitoring system on a machine comprising:

a payload sensor configured to generate a plurality of payload data corresponding to a payload amount in a bucket of a machine, the plurality of payload data comprising a first payload data and a second payload data; and

a controller configured to;

receive the first payload data from the payload sensor and off-board payload data from an off-board system,

compare the first payload data to the off-board payload data to generate a payload data offset,

receive the second payload data from the payload sensor, and

generate an adjusted payload data based on the second payload data and the payload data offset.

2. The payload monitoring system of claim 1, wherein the plurality of payload data is based on a movement of the bucket.

3. The payload monitoring system of claim 1, wherein the machine is an excavator.

4. The payload monitoring system of claim 1, wherein the controller is configured to communicate the adjusted payload data to a bucket control system.

5. The payload monitoring system of claim 4, wherein the bucket control system is configured to regulate the payload amount based on the adjusted payload data.

6. The payload monitoring system of claim 1, wherein the off-board system is configured to communicate the off-board payload data to the controller.

7. A payload monitoring system comprising:

a first machine comprising;

a bucket,

a payload sensor configured to generate a plurality of payload data corresponding to a payload amount in the bucket, the plurality of payload data comprising a first payload data and a second payload data; and

a controller configured to;

receive the first payload data from the payload sensor and off-board payload data from an off-board system,

compare the first payload data to the off-board payload data to generate a payload data offset,

receive the second payload data from the payload sensor, and

generate an adjusted payload data based on the second payload data and the payload data offset; and

an off-board machine comprising;

a receiving area and

an off-board payload sensor configured to generate off-board payload data.

8. The payload monitoring system of claim 7, wherein the first machine is an excavator.

9. The payload monitoring system of claim 7, wherein the controller calculates a weight of a payload based on a movement of the bucket from payload data from the payload sensor.

10. The payload monitoring system of claim 7, wherein the off-board machine is a mining truck.

11. The payload monitoring system of claim 7, wherein the controller is configured to send the adjusted payload data to a bucket control system.

12. The payload monitoring system of claim 11, wherein the bucket control system can adjust the payload amount in the bucket of the first machine based on the adjusted payload data.

13. The payload monitoring system of claim 12, wherein the bucket control system controls one or more of a boom, a stick, and the bucket.

14. A method of controlling a payload system on a first machine, the method comprising:

providing first payload data from a payload sensor on a first machine having a bucket;

providing off-board payload data from an off-board payload sensor on a second machine having a receiving body;

generating a payload data offset by comparing the first payload data to the off-board payload data;

providing second payload data from the payload sensor; and

generating an adjusted payload data based on the second payload data and the payload data offset.

15. The method of claim 14, wherein the first machine comprises an excavator.

16. The method of claim 14, wherein the second machine comprises a mining truck.

17. The method of claim 14, wherein the first payload data and the second payload data are generated based on a movement of the bucket.

18. The method of claim 14, further comprising adjusting a payload amount in the bucket based on the adjusted payload data.

19. The method of claim 14, further comprising generating a remaining capacity on the second machine based on the off-board payload data.

20. The method of claim 19, further comprising communicating the remaining capacity data to the first machine.
