| description | To enhance the aircraft wire detection rate of fault detecting and locating accuracy, a comprehensive portable test system for wire fault diagnosis using reflectometry was presented to detecting and locating fault location. The hardware system consists of DSP control core, pulse transmitter circuit, signal acquisition circuit and LCD circuit, and in this system, a pulse was launched and a reflected signal was received. After the threshold denoising to the reflected signal based on wavelet decomposition, the exact fault type and location of the wire was determined by least squares method. The experimental results indicate that this system can detect and locate the aircraft wire faults accurately. |
