Abstract

A method of determining payload data of a mining machine having a bucket and a handle. The bucket and handle are rotatably coupled via a pin and an actuator. The method includes sensing, via a sensor, a force associated with the actuator, determining, via a controller, a characteristic indicative of a rotational angle of the bucket, and determining, via the controller, payload data based on the force and the characteristic.

First claim

What is claimed is:

1. A method of determining payload data of a mining machine having a bucket and a handle, the bucket and handle rotatably coupled via a pin and an actuator, the method comprising:
sensing, via a sensor, a force associated with the actuator;
determining, via a controller, a characteristic indicative of a rotational angle of the bucket; and
determining, via the controller, payload data based on the force and the characteristic;
wherein the payload data is determined during a swing deceleration operation.

2. The method of claim 1 , wherein the payload data is a percentage of the bucket filled with a material.

3. The method of claim 1 , wherein the force is a hydraulic force of the actuator.

4. The method of claim 1 , wherein the force is a torque of the actuator.

5. The method of claim 1 , further comprising sensing, via a second sensor, a second force.

6. The method of claim 5 , wherein the second force is a hoist force.

7. The method of claim 1 , wherein the rotational angle of the bucket is relative to the handle.

8. The method of claim 1 , wherein the swing deceleration operation includes a swing deceleration and a dump.

9. The method of claim 1 , wherein the step of determining characteristic indicative of the rotational angle of the bucket is based on a sensed displacement of the actuator and a dimension of a component of the mining machine.

10. An industrial machine comprising:
a base;
a component rotationally coupled to the base;
a bucket rotationally coupled to the component via a pin and an actuator;
a sensor configured to sense a force;
a controller configured to
receive a signal indicative of the force,
determine a characteristic indicative of a rotational angle of the bucket, and
determine a payload data based on the signal and the characteristic,
wherein the payload data is determined during a swing deceleration operation.

11. The industrial machine of claim 10 , wherein the payload data is a percentage of the bucket filled with a material.

12. The industrial machine of claim 10 , wherein the force is a hydraulic force of the actuator.

13. The industrial machine of claim 10 , wherein the force is a torque of the actuator.

14. The industrial machine of claim 10 , wherein the sensor is further configured to determine a displacement of the actuator.

15. The industrial machine of claim 10 , wherein the rotational angle of the bucket is relative to the handle.

16. The industrial machine of claim 10 , wherein the swing deceleration operation includes a swing deceleration and a dump.

17. The industrial machine of claim 10 , wherein the rotational angle of the bucket is determined based on a sensed displacement of the actuator and a dimension of a component of the industrial machine.

18. The industrial machine of claim 17 , wherein the dimension of the component is the distance between a first connection between the bucket and the pin and a second connection between the actuator and the bucket.
