| Abstract: | The optical fiber is received the public attention in many fields due to it's good electromagnetic compatibility and lower attenuation.The limitation of wire-controller area network(CAN) bus is discussed in detail,and its interface protocol is particularly analyzed.By rebuilding the physical layer of CAN bus,a scheme for transmitting the CAN bus signal through optical fiber is proposed.The interface circuits between fiber-CAN bus and network nodes are designed,and the nodes are controlled by CPLD. |
