摘　　要：在数据采集测控系统中,用于检测的绝对值角度编码器的输出很多是基于SSI接口,采用SSI接口的绝对值角度编码器输出有时需要连接到多个不同的独立测控系统,由于SSI接口是单访问接口,多主机共享往往是较难解决又不得不解决的问题,本文提出了一种缓冲式并行读取绝对值角度编码器值的方法,实现了信号的并行读取,并给出了硬件和软件设计的思想和方法。In some measuring and controlling system, many absolute value angle encoder output are based on SSI interface. The output of the absolute value angle encoder based on SSI interface needs to connect many different independent measuring and controlling system. Because the SSI interface has one output, the problem of sharing way of interface often is difficult but must be solved problem. The way that buffer parallel mode is used to read the output value of absolute value angle encoder is proposed in the paper, which realizes the way of parallel reading signals. The idea of designing hardware and software are given.
