摘  要:
针对作物考种对单粒种子质量测量的特殊需要,设计了一种基于应变式称重传感器的单粒种子自动称重装置,能够实现单粒种子质量的自动测量及对一批种子的质量谱分布测量。测量过程中,该装置将实时显示每粒种子的质量,并按照预先设定的质量阈值将种子分为两类;测量结束后,将两种类别种子的数目、种子的总个数、平均质量、标准差、总质量滚动显示在单片机控制的液晶屏幕上,并在LabView开发的程序中显示质量谱分布的柱状图。

摘  要:
The crop seed weight distribution is an important factor.At present,it is a time consuming and boring work to test crop seed weight distribution.To meet the need of seed research,in this thesis we explain a design of automatic equipment which is used to test crop seed weight.This device could test the weight of seed one by one with low error.This device is made up of test part and auto seed transportation part.The test part contains a single point load cell,amplifier,filter,and MCU.The transportation part is realized by a signal seed metering device,a seed brush,a seed recycle container,and a separator.This device can display the mean weight and absolute deviation of an array of seeds,the number of seeds,the total weight of seeds,and the numbers of two separated seeds.
