摘要
针对飞机故障的产生逻辑和处理方法,详细分析了中央维护计算机系统故障数据处理模块的主要功能,建模思想和处理流程;再现了故障信息产生、级联效应删除、重复故障合并以及飞机驾驶舱效应与维护信息关联的全过程。并以国外先进机型为例,对基于逻辑方程的故障隔离技术进行了深入分析,使得系统设计思路与机载故障诊断模型相结合;随着CMCS技术的不断发展和成熟,必将对商用飞机传统维护模式和运营模式产生深远的影响。
Based on knowledge on how failures are generated and processed onboard the aircraft, Implement functions, modeling strategy and experienced procedure of fault data processing including in central maintenance computer system （CMCS） are analyzed. Fault message generation, cascaded fault screening, multiple fault consolidation and flight deck effect （FDE） correlation with maintenance message are present respectively. It is critical that logic equation--based fault isolation technology is discussed for correlation design strategy to fault diagnosis module by taking foreign advanced airplane model as the example. With the development and maturity of CMCS, maintenance and man agement mode for commercial vehicle are changed inevitability.
