摘　　要：为了实现在不增加体积和重量的前提下提高绝对值编码器分辨率和测量精度,对绝对值编码器接口相关电路进行了研究和设计。其中,选用基于AM3358处理器的Beaglebone Black作为Linux嵌入式开发平台,将系统控制统一在Python语言的开源框架中,采用SSI协议的通讯方式发送控制信号,以此检测绝对编码器的基本性能。通过测试实验,证明了该绝对值编码器接口电路设计方案可行,具有可靠的绝对值编码器测量精度和分辨率。In order to improve the resolution and measurement accuracy of absolute encoder without increasing volume and weight,the interface circuit of absolute encoder is studied and designed.Among them,Beaglebone black based on AM3358 processor is selected as the Linux embedded development platform,the system control is unified in the open source framework of Python language,and the control signal is sent by the communication mode of SSI protocol,so as to detect the basic performance of absolute encoder.Through the test experiment,it is proved that the design scheme of the interface circuit of the absolute value encoder is feasible and has reliable measurement accuracy and resolution of the absolute value encoder.
