摘　　要：车桥总成信息系统是车桥生产企业可追溯管理实现的关键组成部分,对系统可用性要求高。为了实现该目标,在设计系统时充分考虑了故障的自诊断和软件容错的实现,介绍了在这个复杂工业网络中分部分使用的多种方法,文章最后给出了一些关键代码。实践证明这些方法是有效的,实现了系统的高可用性。Vehicle- bridge assembly Information Systems is the key component of quality information management. The system needs a high availability. On the basis of analyzing the fail- over factors of a system and the structure of high availability system, this paper starts from the types and functions of the high availability system, designs a high availability system software framework which can realizes malfunction diagnosis and fault- tolerant. Especially in a complex industry network it is divided the three parts to deal with. And the paper gives the system chart and the key source code. Practice has proven methods to improve the reliability of the system.
