数控机床中光电编码器计数电路设计

Design of Count Circuit of Encoder in CNC Machine Tool

光电编码器在具有高频振动的环境中使用时，将引起输出波形的畸变，导致计数错误。文章在分析其原因的基础上，设计了一个简单的计数电路。

s:When an encoder works in environment with high frequency vibration, the output signal of the encoder will be distorted. This will generate errors to the count result. So we designed a simple circuit to reduce this kind of errors. Experiments prove that the circuit is feasible and efficient.
