本文讨论了如何实现两级旋转编码器的级联,并利用级联的两级旋转编码器建立一个能够对位移或旋转角度进行大范围连续精密测量的坐标系统。此坐标系统可以应用在各 种对位移或角度的测量有特殊要求的工业控制过程中,它具有分辨率高、范围广和掉电后数据不丢失等特点。 【关键词】 旋转编码器; 级联;高精度 【【Abstract】 This paper discusses the realization of the cascade of two stage rotary coder. The realization is aimed to establish a coordinate system to apply the continuous and precision measurement of the displacement and rotary angle in a large scale. The coordinate system can be used for any industrial control process in which there are particular demands for the measurement of the displacement and rotary angle. It has characteristics of high resolution, large scale and non-volatile. 【Key Word】rotary coder ; cascade ;high-accuracy
