Quantity distribution calculation device and quantity distribution calculation method

摘要

The quantity distribution calculation device includes an acquisition unit, a determination unit, and a calculation unit. The acquisition unit acquires a position detection value, which is a detection value of the GNSS receiver that detects the position of the combine, and a quantity detection value, which is a detection value related to the quantity of the combine. The determination unit determines whether the area of the pavement where the combine has harvested is an unpassed area or a cylinder area, based on the position detection value acquired by the acquisition unit and the data on the width of the combine that has been harvested. The calculation unit stores the quantity indicated by the quantity detection value in correspondence with the non-passed area when the area determined as the non-passed area is included in the area through which the combine has passed, and the area through which the combine has passed is the cylinder area. In the case of determination, a process of not storing the quantity of water indicated by the quantity detection value in association with the cylinder passage area is performed to calculate the quantity distribution, which is the distribution of quantity of water according to the position.
