【摘要】 随着生产的不断发展,对直线大位移的测量提出了更高的要求.为此提出了一种以摆动式机械接触滚轮为基本原理,基于霍尔元件进行信号检测的直线大位移测量方法.该方法是一种直接以运动部件自身为静止参照物的自为基准测量方式,将两物体的相对直线运动转变为滚动轮的转动,霍尔元件检测滚动轮的转动角度和方向来计算位移.该方法具有结构简单、测量装置体积小、量程大及适应环境广等优点,有一定的应用价值.更多还原

【Abstract】 With the further development of production,a higher request to the measurement of straight-line long displacement has been put forward. This article introduces one technique swayings mechanical contact whell based on Hall componets to measure straight line long displacement.This method directly takes movement part oneself as static reference datum,converting two objects relative movement to the rotation of wheel.the Hall componets detect the rotation angle and the direction of roll wheel,then the displacement is calculated.The measuring technique has many merits,such as simple and small measuring structure,large measuring range,broaden adaption environment and so on,so having certain application value.更多还原
