Key Technologies of ARINC664 Bus Testing

In this paper, a PXI-based avionics bus test system for ARINC 664 is developed using C# language and NI Measurement Studio. The system uses "Platform Invoke" technology to invoke the built-in functions in DLL files provided by the PXI-C664 board. The network configuration tool and avionics bus test tool are built in the system. The first tool aims to generate the AFDX end system configurations, while the second is used to test the AFDX end systems. The avionic bus test tool has integrated two test methods which realize data sending and data receiving. Finally, the bus test system is used to test the end system of AFDX.
