编码式传感器的软件辨向与实现

Discerning Direction by Software for Encoder Sensor and Its Realization

编码式传感器应用于精密测量时,由于旋转轴的晃动可能引起传感器输出波形的抖动,从而导致计数错误。文章从波形分析入手,提出了一种基于纯软件编程的方法,解决了上述问题,简化了电路设计。

When using encoder sensor in precise measurement, the shaking of rotation axis can cause change of output waveform of sensor and wrong count. The paper began with analysis of waveform, then put forward a method based on software, which solves the above-mentioned problems and simplifies the design of circuit.
