通过对传统绝对式码盘编码方法原理的研究，提出了一种新型的编码方法——单圈绝对式编码方式．根据设计的码盘位数，运用VC语言进行可视化编程，得出角度位置和编码一一对应的编码．该图形简单，制作方便，易于提高准确度和实现编码器的小型化，克服传统绝对式码盘码道数过多、结构复杂、刻划难度大、编码准确度低等缺点，为进一步研制单圈绝对式编码器提供了理论依据和技术支持．

A new encoding method,which was single ring absolute encoding mode,was put forward by studying the encoding principle of traditional absolute code disc. Based on the designed digit of code disc,the codes that correspond to angle positions were obtained by using VC to program. The pattern was simple and the photolithography technology was easy. The precision of encoder was improved easily and the type of encoder can be made miniature lightly,whose core component is the code disc with the pattern.The method overcame the disadvantage of traditional code disc patterns such as more tracks,complex configuration,difficult photolithography and low encoding precision,and provides theories and technologies of encoding to develop further single ring absolute encoder.
