Abstract

In this paper, a new encoding method for single-track absolute shaft encoder is introduced based on the analysis of the characteristics of the code. This code using the new method has the characteristics of customizable code length and good code balance, which solves the problem that the traditional code length can only be some discrete value and the problem of poor code balance. The new code has abundant redundant information, based on which, it is easy to distinguish whether there is fault in the code recognition.
