随着电子工业和测量元件的发展,光学数字显示器日趋广泛地在各部门得到应用,主要用于长度和角度的精密检测,具有精度高、非接触测量等优点。目前国内使用的这类数显器基本上是增量式的,由光栅尺取得的脉冲信号来进行计数。为了避免计数错误,要求系统有较高的抗干扰能力。从提高可靠性及运行速度的目的,我们试制了一台用状态计数的对位置有记忆功能的十进制绝对码数字显示器,经过
With the development of electronic industry and measurement components, optical digital displays are widely used in various departments. They are mainly used for the precise measurement of length and angle, and have the advantages of high precision and non-contact measurement. Currently used in this type of digital display is basically incremental, obtained by the grating pulse signal to count. In order to avoid counting errors, the system requires a higher anti-interference ability. In order to improve the reliability and speed of the purpose, we have trial production of a status counter memory location of the decimal absolute code digital display, after
