摘要
对飞机电源系统智能BIT技术的发展现状进行了分析和总结,从提高故障诊断效能、降低虚警率等方面阐述了智能BIT需要解决的问题,并针对这些问题,从部件级故障模式分析、基于模糊神经网络的故障诊断方法、系统级故障预测、构建集成神经网络与降低虚警率等方面,提出了一个发展飞机电源系统智能BIT的系统解决方案,为提高飞机电源系统可靠性、测试性、维护性的深入研究打下了基础。
The causes of intelligent BIT in aircraft powersystem are analyzed. The Problems are discussed according to improve efficiency of fault diagnosis and reduce false alarm. A scheme for their solutions is presented from the following aspects:false pattern analysis in part level, fault diagnosis via neural network, false forecast in system level, integration network for reducing false alarm, etc, which lays the foundation for the study of reliability, mensurability, maintainabilityof aircraft power system.
