Title:
POSITION DETERMINATION METHOD, APPARATUS AND DEVICE FOR HYBRID ENCODER, AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/017075
Kind Code:
A1
Abstract:
A position determination method for a hybrid encoder. The method comprises: acquiring a first electrical signal output by a magnetic induction chip in a hybrid encoder and a second electrical signal output by a photosensitive element (S11); acquiring, according to the first electrical signal, a reticle value and a value of the number of turns of an absolute position at the current moment (S12); acquiring, according to the second electrical signal, a reticle phase angle of the absolute position at the current moment (S13); and further determining position information of the hybrid encoder (S14). The position determination method for a hybrid encoder is simple throughout the whole resolving process and has a high accuracy, thereby facilitating the wide application of the hybrid encoder. Further provided are a position determination apparatus and device for a hybrid encoder, and a computer-readable storage medium.
