CAN USING DC-PLC AND ORTHOGONAL CODE METHOD

摘要

A CAN(Controller Area Network) using a DC(Direct Current) PLC(Power Line Communication) orthogonal code scheme is provided to enable various nodes to simultaneously transmit important and urgent data through a CAN bus, thus the important data are effectively processed in real time. A CAN(200) comprises the followings. Orthogonal code type modems(210) form various patterns by multiplying orthogonal codes by data, and restore original data of the multiplied data. DC-PLC type DC power line couplers(220) transceive the data through a DC power line(230). The orthogonal code modems(210) modulate/demodulate the data into orthogonal codes. The DC power line couplers(220) load the data on the DC power line(230).
