【Abstract】 Because of the obvious advantages of optical fiber, optical CAN network has been widely used in many rigorous industrial environment such as electric vehicle control systems. Based on the analysis of the advantages and disadvantages of different topological structures of the optical CAN network and the choice of optical fiber and its transceiver,a developing method of the double ring network is proposed and a related optical ring interface of CAN is implemented.更多还原
