摘　　要：设计了一种基于双冗余CAN总线、支持可更换操作的高可用计算机系统。介绍了高可用计算机系统r的组成和更换模式;设计了基于控制器级冗余的通讯系统结构;采用MPC8313处理器实现了高可用计算机原型系统。验证实验表明,该系统实现了计算机模块的可更换,具有较高的可靠性和可用性。A high available computer system is designed which is used double redundant can -bus and supports operation of replacement. Firstly, the form of computer system, replacement pattern and the design of communication system are introduced. Secondly, the structure of communication system is designed which is based on the redundant of can - controller. At the end, the computer prototype with high availability is used the processor of MPC8313. The system test result shows that the system has achieved the replacement of the computer modular ,has characteristics of high reliability and practicality.
