摘要:

为实现少样本下民机空调系统的有效健康评估,解决空调系统时间维度下状态评估这一难题,提出一种融合故障逻辑与贝叶斯时变评价网络的评估方法。首先,基于系统工作原理构建“监测指标–部件–系统”三级评价框架,以故障逻辑图明确监测指标与部件状态的关联关系。其次,引入时间因子和信息熵–独立性权重系数耦合赋权策略,建立时变?综合赋权模糊综合评价方法,实现部件时间维度下的健康状态量化。然后,结合博弈均衡驱动的贝叶斯网络,将部件状态映射至系统状态,形成贝叶斯时变耦合赋权模糊综合评估模型(Bayesian time-varying coupling weighted fuzzy comprehensive evaluation model, BTCW-FCEM),实现系统级健康状态的动态评估。最后,基于国产民机空调系统运行监测数据开展单部件与复合部件故障案例分析,验证模型在健康状态动态评估中的高精度与高效率表现。结果表明,BTCW-FCEM在多类故障场景下的准确率、精确度、召回率和F1分数均优于多种对比模型,为民机空调系统的健康监测与故障预警提供了可靠的技术支撑。

Abstract:

To effectively achieve health assessment of civil aircraft air conditioning system under limited sample conditions and address the challenge of evaluating state in the time dimension of air conditioning system, an assessment method that integrates fault logic with a Bayesian time-varying evaluation network is proposed. Firstly, based on the system operating principles, a three-level evaluation framework of “monitoring indicators–components–system” is constructed, and a fault logic diagram is employed to clarify the relationships between monitoring indicators and component states. Secondly, a time-varying comprehensively weighted fuzzy comprehensive evaluation method is established by introducing a temporal factor and information entropy independence weight coefficient coupling weighting strategy, enabling quantify health status of components in the time dimension. Thirdly, a game-equilibrium-driven Bayesian network is incorporated to map component states to the system state, forming the Bayesian time-varying coupling weighted fuzzy comprehensive evaluation model (BTCW-FCEM) for dynamic assessment of system-level health. Finally, case studies on single component and composite component faults are conducted using operational monitoring data from a domestic civil aircraft air conditioning system, validating the high accuracy and efficiency of model in dynamic health assessment. The results show that the BTCW-FCEM outperforms multiple comparative models in terms of accuracy, precision, recall, and F1 score in various fault scenarios, providing reliable technical support for health monitoring and fault warning of civil aircraft air conditioning systems.
