Aircraft Cable with Connector Fault Modeling and Diagnosis

ABSTRACT

The aircraft complex across multiple conn paper, set up the aircraft cable cross connector open defect mathematical model and corresponding simulation model, the time domain reflection method is used to calculate and analysis the transformation rule of characteristic impedance and reflection coefficient when the aircraft cable across one or more connector. The aircraft cable open defect with a narrow delay pulse waveform across one or more connector reflection and transmission is researched in Matlab Simulink, the aircraft cable connector fault diagnosis system is built in the industrial computer hardware platform and the LabVIEW software. The experiment result showing: simulation model in the aircraft cable open defect multiple cross connector is scalable, waveform identification level is high, at high sampling rate in the hardware platform can realize aircraft cable connector fault diagnosis and locating.
