In order to solve the integrity problem of the current aviation bus ARINC 825, a test terminal system is designed. The scheme adopts modular design and describes the software design of the system. The system implements functions such as data monitoring, data transmission, data analysis, data recording, data filtering and data display were realized. The system can maximize meet the testing requirements of avionics systems. The bus data status can be viewed in real time to facilitate real-time monitoring of aircraft avionics bus data and troubleshooting of on-board test systems. The experimental results show that the aviation bus test terminal system has good stability, high reliability and convenient to use, and meets the design requirements.
