舰船公共电子信息链路故障传播分析技术

Fault Propagation Analysis Technology of the Public Electronic Information Link for the Combat Ship

舰船信息化水平的大幅提升使舰船电子信息集成架构较之以往更为简约、集成度更高,其核心的舰船公共电子信息链路(设备)在给全船各功能系统(设备)带来资源共用的同时,也潜在地将各个功能系统紧密耦合起来,增大了故障传播影响范围风险。进行故障传播分析是保障全船系统安全可靠运行的前提和关键。论文对当前故障传播分析方法的研究进展进行了梳理,并着重从系统模型复杂度、数据依赖性和节点要求等几方面进行对比分析,初步提出了采用复杂网络理论来描述故障传播路径的方法,以期为后续应用研究提供支撑。

With the continuous improvement of the ship informatization,the architecture of the electronic information system is more simpler and more integrated than before.The public electronic information link not only brings sharing resource to the whole ship's functional systems,but also potentially combines each functional system closely,which will increase the risk of fault propaga⁃tion.Fault propagation analysis is an effective means to ensure the safe operation of the system and obtain reliable system perfor⁃mance.This paper introduces the basic theory and the research progress in the field of fault propagation,and then compares those methods with the model complexity,data dependence and the demand of nodes.Finally,a method of using complex network theory to describe the fault propagation path for the public electronic information link is proposed,which is expected to provide support for subsequent application research.
