Abstract

The traditional Automatic Test Equipment (ATE) systems are insufficient to cope with the challenges of testing more and more complex avionics systems. In this study, we propose a general method for module automatic testing in the avionics test platform based on PXI bus. We apply virtual instrument technology to realize the automatic testing and the fault reporting of signal performance. Taking the avionics bus ARINC429 as an example, we introduce the architecture of automatic test system as well as the implementation of algorithms in Lab VIEW. The comprehensive experiments show the proposed method can effectively accomplish the automatic testing and fault reporting of signal performance. It greatly improves the generality and reliability of ATE in avionics systems.

Highlights

Along with the development of electronics and information technology, the avionics systems are becoming more and more complicated, leading to a much higher requirement of automatic testing for system reliability (Allen and McNeil, 1994; Craig, 2002; Ross, 2005; Dong and Li, 2009; Steadman et al, 2002)
Aiming at the insufficiency of Automatic Test Equipment (ATE) and the future trend of automatic test technology, we propose a generalized automatic test method for avionics modules, with application to the avionic test platform based on PXI bus
ARINC429 bus signal that satisfies the amplitude and rate requirements can be generated by the arbitrary waveform generator and waveform editing software to realize signal imitation and stimulation of Unit Under Test (UUT)

Summary

Introduction

Along with the development of electronics and information technology, the avionics systems are becoming more and more complicated, leading to a much higher requirement of automatic testing for system reliability (Allen and McNeil, 1994; Craig, 2002; Ross, 2005; Dong and Li, 2009; Steadman et al, 2002). ARINC429 bus signal that satisfies the amplitude and rate requirements can be generated by the arbitrary waveform generator and waveform editing software to realize signal imitation and stimulation of Unit Under Test (UUT). The test resources of ARINC429 bus module signal test system include ARINC429 bus communication module, digital oscilloscope module, digital multimeter module, arbitrary waveform generator module and relay module.
