循环码转换的软件实现法

The software method to realize cyclic code′s changing

将绝对式光电脉冲发生器的循环码转换电路改由易修改易维护的软件(程序)来实现,该软件可将光电循环编码盘采集的检测信号准确地转换成二进制代码,再输入到单片机的I/O口,不仅提高了脉冲发生器工作的准确性,而且简化电路,节约成本。

In this paper, the design of easily alternating and maintaining software （program） which can realize cyclic code changing in absolute pulse generator is introduced. The software can acurately transform sense information from phototube cyclic code plate into binary code which inputs into single microcomputer＇s I/O interface. It not only increases accuracy of absolute pulse generator, but also simplifies electric circuit and saves cost.
