在明确测量任务的前提下，对增量式编码器的工作原理以及对其输出信号四细分处理的方法进行研究，在此基础上利用Proteus仿真软件对旋转编码器原始信号及经过四细分处理信号进行仿真分析，为合理选择硬件电路元器件找到充分的依据。进而构建了以AT89 S52单片机为主控单元，增量式编码器为前端传感器，外加中间四细分辨相处理电路，选用LCD液晶显示器显示测量结果，实现信号采集和数据处理的硬件检测系统，所构建的硬件检测系统电路结构简单、成本低。

With a clear understanding of measurement tasks, this paper studied the working principle of photoelectric encoder and method of Fourfold Frequency processing of the output signal.Based on this, a sim-ulation analysis was made of the original signal and fourfold frequency signal by Proteus software so as to pro-vide a sufficient basis for selection of hardware circuit components.And then a hardware detection system was constructed, using the AT89S52 single chip microcomputer as the main control unit and a photoelectric en-coder as the front sensor, plus Fourfold Frequency processing circuit, and selecting LCD ( liquid crystal dis-play) to display measurement results, acquire signals and process data.The circuit of hardware detection sys-tem was simple in structure and low in cost.
