System and method for estimating a payload of an industrial machine
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.
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.
