Design and research of an ARINC 429 bus testing system

An ARINC429 bus testing system is designed based on FFT processor, which aims at the technology of ARINC429 bus data communication. It controls tested module by controlling bus. In other words, the performance of ARINC 429 bus is tested by testing address bus and data bus. The testing system is based on ARINC429 bus specification and adopts universal ARINC429 special component DEI1016 and BD429 to form a core unit of the testing system. At last, it can achieve how to diagnose and locate fault by using VISA technology of LABVIEW, expert system and BP neural network.
