Abstract
A method for providing robust and reliable transmission of shaft encoder signals. Initially, the differentially encoded shaft encoder signals are received. The shaft encoder signals are converted into single-ended electrical signals. These single-ended electrical signals are then converted into optical signals. Finally, the optical signals are transmitted through optical conductors.
Claims16
A system, comprising:
- a rotating shaft having shaft movement parameters;
- an incremental shaft encoder to convert the shaft movement parameters of the rotating shaft into differentially encoded electrical signals suitable for processing;
- a first optical converter to convert the differentially encoded electrical signals into optical signals;
- a plurality of optical conductors to carry the optical signals;
- and
- a second optical converter to receive and convert the optical signals back into electrical signals.
