摘　　要：对于电厂高可靠性系统,现场总线控制系统的安全性还有进一步改进的要求。TTCAN是基于传统CAN总线的一种高层协议,其通信是基于时间触发的,因而适用于安全相关的场合。本文主要对传统TTCAN硬件结构进行了改进,据此提出了一种双通道TTCAN冗余总线方案及其冗余管理策略。For a power plant which has a high reliability, the security of FCS needs more improvement of technology. TTCAN is a higher-layer protocol placed on top of the unchanged CAN protocol, it based on time-triggered so that it is useful to some safety applications. The paper mainly discussed the improvement of traditional TrCAN hardware structure. Then put forward a new management of redundancy TTCAN system according to the new structure

关 键 词：TTCAN协议 冗余 时间触发
