Serial isolation communication method, device and system

Abstract

A serial isolated communication method, applied to a transmitter of a serial isolated communication system, includes: obtaining isolated communication data to be transferred; encoding isolated communication data with more than two bits into corresponding data pulse signals according to a preset encoding rule, wherein a group of data pulse signals include a positive pulse, a negative pulse, and a delay of 0 or N pulse widths between the positive pulse and the negative pulse, and N≥1; and transferring the data pulse signals to a receiver. A serial isolated communication method, applied to a receiver of a serial isolated communication system, includes: receiving data pulse signals transferred from a transmitter; decoding the data pulse signals into the isolated communication data according to a preset decoding rule; and obtaining the isolated communication data. Serial isolated communication device and system are further provided.
