Design and implementation of aeroengine fault diagnosis system
摘要
Abstract
Aeroenginge fault diagnosis system is designed and implemented using a hybrid programming of LabVIEW, C and MATLAB. DLL driver for data acquisition instrument is designed via C language, and LabVIEW called which to acquire data. According to the characteristics of aeroengine’s vibration signal, this paper designs signal processing and feature extrac-tion module. MATLAB is employed to compile COM component of support vector machine optimized by multi algorithms, and LABVIEW called the component to implement fault diagnosis. Database management module is designed using Data-base Connectivity Toolkit. The system is tested on the aeroengine rotor experimental rig, and the results not only indicate its high accuracy but also verify the feasibility of the design idea in the paper.关键词
