民航发动机健康管理系统数据库设计与实现

摘要

Because of the characteristics of the condition-based maintenance of modern civil aviation engines ,the key of monitoring is acquisition of huge amount of performance data .An aero-engine health management system database with B/S structure is designed to implement data management of aircraft engine running information .By use of fault diagnosis module ,taking the existing APU faults in the system as example ,the empirical TCBR diagnosis method is applied to fault diagnosis .The results show that the database search function is realized ,and fault diagnosis is timely and effective .The design of the database will improve the engine running information management ability ,and enhance the level of health management .%基于现代民航发动机视情维修模式的特点，监控中获取的海量性能数据成为关键。以B／S架构设计并实现健康管理系统数据库来管理飞机发动机运行信息。针对故障诊断模块，以系统中辅助动力装置的故障为例，运用TCBR方法诊断验证，结果显示：数据库可实现搜索功能并及时准确诊断故障。设计的数据库提高了发动机运行信息管理能力，有助于提升健康管理水平。
