Abstract
Determining dipper geometry. A method of determining dipper geometry includes obtaining a first set of data associated with an industrial machine for a first orientation of the industrial machine, and obtaining a second set of data associated with the industrial machine for a second orientation of the industrial machine. The first set of data includes at least one of a first length associated with a hoist rope and a first angle associated with the hoist rope, and the second set of data includes at least one of a second length associated with the hoist rope and a second angle associated with the hoist rope. The value of the physical characteristic of the dipper is then determined based on the first set of data and the second set of data.

A method of determining a value of a physical characteristic associated with a dipper of an industrial machine, the method comprising:
- obtaining a first set of data associated with an industrial machine for a first orientation of the industrial machine, the first set of data including at least one of a first length associated with a hoist rope and a first angle associated with the hoist rope;
- obtaining a second set of data associated with the industrial machine for a second orientation of the industrial machine, the second set of data including at least one of a second length associated with the hoist rope and a second angle associated with the hoist rope;
- and
- determining, using a processor, the value of the physical characteristic of the dipper based on the first set of data and the second set of data.
An industrial machine comprising:
- a dipper;
- a boom and a sheave supporting a hoist rope, the hoist rope connected to the dipper;
- and
- a controller configured to
- control a length of the hoist rope,
- determine a first length of the hoist rope, the first length corresponding to a first position of the dipper,
- determine a second length of the hoist rope, the second length corresponding to a second position of the dipper,
- determine a first angle of the hoist rope with respect to the sheave, the first angle corresponding to the first position of the dipper,
- determine a second angle of the hoist rope with respect to the sheave, the second angle corresponding to the second position of the dipper,
- determine a displacement of the hoist rope based on the first length, the second length, the first angle, and the second angle, and
- determine a value for a physical attribute of the dipper based on the displacement of the hoist rope.
A method of determining a value for a length associated with a dipper of an industrial machine, the method comprising:
- determining, using a processor, a first length of a hoist rope associated with a first position of the dipper;
- determining, using the processor, a first angle of the hoist rope with respect to a sheave and associated with a first position of the dipper;
- determining, using the processor, a second length of the hoist rope associated with a second position of the dipper;
- determining, using the processor, a second angle of the hoist rope with respect to the sheave and associated with a second position of the dipper;
- and
- determining, using the processor, the value for the length of the dipper based on the first length of the hoist rope, the second length of the hoist rope, the first angle of the hoist rope with respect to the sheave, and the second angle of the hoist rope with respect to the sheave.
