A General Method for Module Automatic Testing in Avionics Systems

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.

Assessment of Health Monitoring Trustworthiness of Avionics Systems

“…Modern ATE are built on a modular principle using interface PXI bus and standard digital interface for programmable instrumentation IEC-60488-1 (2004) and IEC-60488-2 (2004). There are two primary directions of ATE development: generality and openness (Ma et al, 2013); the main aspects of these directions investigated by (Droste & Guilbeaux, 2009), (Evlanov, 1979), and (Stora & Droste, 2003).…”
