 摘要：由于光纤自身的众多优势,CAN (controller area
network)总线光纤网络已在汽车控制系统等具有恶劣环
境的工业领域中得到越来越多的应用。本文首先分析
了CAN总线光纤网络可采用的几种网络拓扑结构的优
缺点,讨论了光纤及其收发器的选择,开发了CAN总线
的环型光纤接口并提出了双环网络的实现方案。 |

| Design of Double Ring Optical CAN Network |
| 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. |
