自动控制系统在用光学的或接触式的编码盘对轴角进行编码时,常用循环码或直接二进制码,而实用中往往需要用十进制角度值直接显示轴角大小。由于编码盘给出的二进制代码的权与用以译码获得十进制角度值的二进制代码的权不等,所以必须进行代码权转换。本文简要地讨论了这一问题的原理、方法和电路。 设来自编码盘的二进制代码B[b_(n-1),…,b_0]有n位,其轴角分辨率则为R_(es)=360°/ Automated control systems often use circular codes or direct binary codes when encoding shaft angles with optical or contact-type encoder discs, and often require the use of decimal angle values ​​to directly display shaft angle magnitudes. Since the code disc gives the binary code the right to decode the binary code to obtain the decimal value of the angle ranging from the right, so the code must be converted. This article briefly discusses the principles, methods, and circuits of this problem. Suppose that the binary code B [b_ (n-1), ..., b_0] from the code disk has n bits and its angular resolution is R es = 360 ° /
