Development of Testing System for ARINC825 Bus

Studying of aviation bus constitutes an important topic in the field of aeronautics. ARINC825 bus, as a widely-spread aviation bus, is capable of transmitting and sharing information in real time. Aiming at evaluating the working performance of ARINC825 bus, a testing system is designed and deployed. In this way, testing of data transmission, monitoring and analysis can be conducted. Further, the bus data status can be viewed simultaneously to facilitate the monitoring of aircraft avionics bus data and preventing fault from the on-board test systems. The experimental results show that the proposed testing system has good stability, high reliability and is convenient to use, which enables precise testing of the ARINC825 aviation bus.
