Serial isolation communication method, device and system

A serial isolated communication device, applied to a transmitter of a serial isolated communication system, comprising:

• a first acquisition module, configured to obtain isolated communication data to be transferred;
• an encoding module, configured to encode isolated communication data with more than two bits into data pulse signals corresponding to the isolated communication data with more than two bits according to a preset encoding rule, wherein a group of the data pulse signals comprises 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;
• wherein the group of the data pulse signals is contained within a clock period;
• and
• a transferring module, configured to transfer the data pulse signals to a receiver.

A serial isolated communication method, applied to a receiver of a serial isolated communication system, comprising:

• receiving data pulse signals transferred from a transmitter;
• decoding the data pulse signals into isolated communication data with more than two bits corresponding to the data pulse signals according to a preset decoding rule, wherein a group of the data pulse signals comprises 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;
• wherein the group of the data pulse signals is contained within a clock period;
• and
• obtaining the isolated communication data.
