Combine bin level monitoring system

摘要

A combine bin level monitor may include a yield monitor to determine how much grain has been added to the combine tank, a container weighing system (e.g. scales on a grain cart) that measures the amount of grain unloaded from the combine tank and wirelessly transfers the amount to the combine bin level monitoring system. The system further includes a software routine in the combine bin level monitoring system that calculates and displays the bin level by adding grain accumulated by the yield monitor and subtracting grain accumulated by the container weighing system from the last known amount of grain in the combine tank. The accumulated grain is the amount accumulated since the last time the amount of grain in the combine tank was known.

1. A combine bin level. monitor system comprising:
a yield monitor configured to determine an amount of grain added to a combine tank during a crop harvesting event; a container weighing system configured to measure an actual amount of grain unloaded from the combine tank into a container associated with the container weighing system during a combine tank unloading event and wherein the container weighing system comprises at least one sensor and a wireless transmitter operatively connected to the at least one sensor to wirelessly transfer data indicative of the actual amount of grain unloaded from the combine tank into the container associated with the container weighting system during the combine tank unloading event; an intelligent control operatively connected to a wireless receiver in operative communication with the wireless transmitter and the intelligent control operatively connected to the yield monitor and wherein the intelligent control is configured to receive through the wireless receiver the actual amount of grain unloaded from the combine tank into the container associated with the container weighing system during the combine tank unloading event and update a bin level by adding the amount of grain added to the combine tank during the crop harvesting event and subtracting the actual amount of grain unloaded from the combine tank into the container associated with the container weighing system during the combine tank unloading event; and wherein the intelligent control is further configured to compensate for grain in an unloading auger by using an unloading auger grain flow rate calibration specific to a range of amount of grain in the tank.
