Time of flight grain cart fill sensor with combined spout as scanning head

Abstract

Systems and methods are disclosed for sensing and analyzing filling of a grain cart while receiving grain from a combine. Time-of-flight sensors may be mounted on a grain spout (or nozzle) extending from the combine over the grain cart during operation. The sensors provide signals indicative of distances of surfaces of accumulating grain from the sensors, and these distances may be determined by onboard processing circuitry. A third sensor may detect a spout-to-ground distance to help compute the grain level information. Other parameters such as cross-sectional areas, volumes, and locations in the cart may be determined based on the sensed signals. Open or closed loop control of cart and/or combine positioning may be provided based on the signals.
