舰艇控制系统冗余以太网设计

Design for redundant ethernet in warship control system

为了提高舰艇控制系统的可靠性,提出了基于QNX操作系统的舰艇控制系统冗余以太网,并且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。介绍了冗余以太网需解决的问题,着重分析了冗余以太网拓扑结构,以太网节点号和网络节点图的自动生成,以太网进程结构和工作过程。实际使用表明,采取的容错措施行之有效,基本达到了设计要求。

To increase reliability of the warship control system,a redundant Ethernet in warship control system based on QNX is introduced,which can realizes malfunction self-diagnosis and software fault-tolerant.Firstly,some problems on designing redundant Ethernet are introduced,focuses research on the topology of Ethernet,the auto-generation of node IDs and Netmap,the architecture and running of process in Ethernet.The practicing results show that these methods are effective and it meets the original design aim.
