摘　　要：根据增量式光电码盘进行位置检测的原理,提出了一种基于可编程逻辑器件CPLD对光电码盘输出信号倍频、鉴相、计数的具体方法,有利于提高被控对象的测量和控制精度以及DSP和CPLD的接口设计。Based on the theory of incremental opto-electric encoder position detection, it gives a method based on CPLD to multiple frequency of the signal of the incremental opto-electric encoder, differentiate its phase and count its number. It's good for the interface between DSP and CPLD and the measure and control precision of controlled object's also can be heightened.
