Agricultural spreader control

摘要

A spreader control system digitally filters noisy load cell measurements and inaccurate flow rate measurements to form an optimal estimate of material weight in a spreader bin. This estimate may be combined with spreader swath width and vehicle speed to determine application rate. When actuators for parameters such as apron speed or gate size are available, spreading rates may be controlled with active feedback.

主权项

1. An agricultural spreader control system comprising:
a weight sensor that measures the weight of a spreader bin; an apron speed sensor that measures the speed of an apron that moves material at the bottom of the bin toward a gate; and, a processor that: receives measurements from the weight sensor and the apron speed sensor, and digitally filters those measurements in combination with material density and gate area information to form an estimate of the weight of material in the bin.
