Harvest Monitor with SmartClean™
is a John Deere exclusive system that gives sugarcane producers the tools
to make data-driven farming decisions to balance yield, crop quality, loss, and productivity.
Common harvest conditions often vary greatly from field to field, and even pass to pass;
making frequent adjustments necessary to achieve optimal cleaning with minimal billet loss. Harvest
Monitor with SmartClean scans crop material in the elevator to determine the level of residue
and trash, while simultaneously detecting cane billets which may be ejected and lost
if cleaning is too aggressive. If the cleaning fan is set too fast,
cane billets may be picked up in the airstream and ejected with trash.
SmartClean uses Sensors to detect billets leaving the cleaning chamber and automatically
reduces fan speed to achieve a balance between effective cleaning, while preventing billet loss.
Key SmartClean components are the primary extractor fan with speed sensor,
fan pressure sensor, cane loss sensor, harvest monitor trash sensor,
elevator speed sensor, and machine controllers.
The controllers process inputs from the trash monitor and cane loss sensors,
and adjusts fan speed according to system settings determined by operator input
on the GreenStar™ display. The fan pressure sensor provides feedback corresponding to fan speed to
help the C make accurate fan speed adjustments as conditions change throughout the field.
With the electronically controlled SmartClean system, system status is communicated to the
operator with three primary icons. These icons appear on the extractor fan set-up screen
when the SmartClean system is activated. The icons display the status of elevator trash,
cane loss, and the field residue estimate. The status icons are displayed next to graph bars
on the SmartClean run screens which relate to the three parameters which are monitored,
and ultimately control the SmartClean system. In addition to the three separate icons,
a color-coding system is used to convey operating condition and status to the operator.
A logical progression of icon background color from gray to yellow, green, and blue
occurs as the machine has started, and systems are enabled and activated.
The outline of the icon and steady or flashing pattern further defines the status of the system
in various stages of activity. A solid icon with a gray outline
indicates that an option is disabled, or is not installed in the system.
A solid icon with a black outline indicates the option is installed, but is turned off.
A flashing yellow icon with a black outline indicates the function control is enabled,
but automatic operation is not enabled. A solid yellow icon with black outline
indicates the function is enabled and ready for automatic operation,
however the primary extractor fan is not running and is preventing activation of the function.
Flashing green icon with a black outline indicates the function control and automation is enabled,
the extractor fan is engaged in working mode however no crop is detected in the elevator.
A solid green icon with black outline indicates that crop is detected in the elevator.
The closed loop of all sensing inputs becomes active when crop is present
and the icon outline changes from black to white.
A flashing blue icon with black outline indicates the function control and automation is enabled,
the primary extractor fan is engaged in working mode, and the function is controlling fan speed,
however no crop is detected. A solid blue icon with black outline
indicates all necessary operating conditions are met and crop is detected. The closed loop
of all sensing inputs becomes active, and the function represented by the blue icon
is controlling fan speed. A solid red icon with a black outline
indicates that a system fault has been detected and is active, preventing that function from
achieving normal operation. A diagnostic trouble code, or DTC, will - be displayed to the operator.
