随着民用航空事业在中国的大规模发展,中国民用航空器的机队数量有了很大的提高,因此针对大规模机队维护与维修成本在民用航空企业占的比重越来越大。本文简要总结了民用航空器的机械故障的特点。针对民用航空器的特点利用分段算法对故障字符进行分段并提取关键字并提出了基于关键字以及案例的搜索算法。最后,本文利用VB6.0完成智能故障经验库的设计工作。 With the large-scale development of civil aviation in China, the fleet of civil aircraft in China has greatly increased. Therefore, the proportion of large-scale fleet maintenance and repair costs in civil aviation enterprises is increasing. This article briefly summarizes the characteristics of mechanical failures of civil aircraft. Aiming at the characteristics of civil aircraft, the segmentation algorithm was used to segment the fault characters and extract the keywords and put forward the search algorithm based on keywords and cases. Finally, this article uses VB6.0 to complete the design of intelligent fault experience library.
