基于.NET的小型涡扇发动机故障判读系统设计与实现

针对某小型涡扇发动机试车数据的故障判读与诊断问题,应用先进的数据库管理技术建立并设计了发动机异常监视和故障诊断系统,包含试车数据异常监视与试车故障诊断2大功能模块.该系统依托.NET开发平台框架,采用以Web技术为中心的B/S(Browser/Server)结构,以Oracle 10.0g作为试车故障信息数据库,同时按照系统的功能需求实现不同试验模式下试车数据故障诊断.试验验证表明:该系统能有效实现发动机性能、控制参数的异常判读和故障诊断.

Design and implement of monitoring and fault diagnosis system for small turbofan engine based on .NET platform

Aiming at the capability of fault monitoring and diagnosis for a small turbofan engine on test-bed,an approach to enginecondition monitoring and fault diagnosis based on advanced database management technologies was developed,and two main functions ofthe system were established. The development framework of the system is .NET platform,and the system architecture is the B/S (Browser /Server) of the Web technology. Test fault information database based on Oracle 10.0g software was used to manage historical fault data andexpert fault rules. The test fault diagnosis in several different experimental modes was performed according to the system functionrequirement. Experiment results show that the developed system is effective to monitor abnormal condition and diagnose faults for the smallturbofan engine.
