Detection for Heading and Attitude Signal Conversion Equipment of Aircraft Based on Virtual Instrument Technology

The scheme adopts computer testing technology, virtual instrument and virtual system technology to realize the automatic detection for heading and attitude signal conversion equipment of aircraft. It greatly improves the test efficiency. Test time was reduced from 30 minutes to 3 minutes. Based on wavelet analysis and hierarchical decision, program module of connected line identification is design and it improves the reliability of program running. Noisy signals are de-noised by automatic zoom function of wavelet transform and that solves the interference problems of AC power supply.
