摘　　要：常用的双总线型CAN冗余网络在恶劣环境下使用时,其抗毁伤性和生存性较差。本文通过将光纤通讯中常用的自愈环保护方式中的环形结构,自动倒换技术以及存储转发的方法应用于双总线型CAN冗余网络中,设计了一种新型的CAN总线双环冗余结构,经过实验证明它具有良好的抗毁伤性和生存性。The anti-destruct capability and survivability of common CAN bus redundant network is poor when it is used in bad conditions. In this paper, a new dual ring redundant network based on CAN bus is designed by adopting dual ring network structure, automatic switching technology and store- and-forward technology, which are widely used in self-healing fiber ring communications. The new redundant network demonstrates good anti--destruct capability and survivability in test experiment.
