摘　　要：传感器布置方案对系统的故障诊断特性有非常大的影响。针对传统的基于系统模型进行传感器布局方法研究存在的系统解析冗余关系(ARR)复杂,难以推导形成具体的数学表达式的问题,提出了一种以系统故障可隔离性为性能指标,基于双因果键合图模型的因果路径分析法。通过分析系统双因果键合图模型的因果路径关系构建系统的故障特征矩阵(FSM),在保证系统故障可隔离性的基础上,得到传感器优化配置方案。最后,以某型舰舰船主动力装置为例建立了系统的键合图和双因果键合图模型,采用提出的方法得到了系统的传感器优化配置方案,并对所提出的传感器优化配置方案进行推导验证,保证了系统主要部件的故障可隔离性。Sensor placement has a great influence on the fault diagnosis characteristics of a system.Aiming at the difficulty of deriving analytic redundancy relation(ARR)for specific mathematical expression in traditional sensor placement method based on system model,a causal path analysis method based on bicausal bond graph model is proposed.The fault characteristic matrix(FSM)of the system is constructed by analyzing the causal path relationship of the bicausal bond graph model.On the basis of guaranteeing the isolation of system faults,the optimal sensor configuration scheme is obtained.Finally,the bond graph and bicausal bond graph model of a certain type of ship main power plant are established,and the optimal sensor configuration scheme is obtained by the proposed method.The proposed optimal sensor configuration scheme is deduced and verified to ensure the fault isolation of the main components of the system.
