Patent ID: 8788245

Claim:
A method of actively biasing a loadpin associated with an industrial machine, the method comprising: receiving a first plurality of signals from the loadpin related to a force applied to the loadpin, the loadpin having a loadpin bias that corresponds to a deviation in the first plurality of signals that produces an error in the measurement of the force applied to the loadpin, the loadpin bias having a first loadpin bias value; generating, by a processor, a first characteristic of the industrial machine based on a first kinematic model of the industrial machine, the first kinematic model based on the first plurality of signals from the loadpin; receiving a second plurality of signals from one or more sensors related to at least one of a hoist parameter, a crowd parameter, and a swing parameter of the industrial machine; generating, by the processor, a second characteristic of the industrial machine based on a second kinematic model of the industrial machine, the second kinematic model based on the second plurality of signals; determining, by the processor, an operational condition of the industrial machine; determining, by the processor, whether the loadpin is able to be actively biased based on the operational condition of the industrial machine; populating, by the processor, one or more angle arrays based on the first kinematic model of the industrial machine and the second kinematic model of the industrial machine when the loadpin is able to be actively biased; calculating, by the processor, a second loadpin bias value based on the one or more angle arrays that compensates for the error in the measurement of the force applied to the loadpin; and setting, by the processor, the loadpin bias to the second loadpin bias value.
