一、国外发展概况收割机监测仪表1967年在东德首先进行了用电子仪器测量谷粒损失的研究工作。费佛(Feiffer)先后用微电子器件研制出一种能指示联合收割机逐稿器分离损失的电子监视器。但这种监视仪器并不是很完善的。事隔不到一年,加拿大萨斯卡大学也开始对谷物损失监视器 First, the foreign development overview Harvester monitoring instruments in 1967 in East Germany conducted a first electronic instrument to measure grain loss research. Feiffer has used microelectronics to develop an electronic monitor that indicates the separation loss of the combine harvester. However, this monitoring equipment is not perfect. Less than a year later, the University of Saskatchewan has also begun to monitor grain loss
