Design of Data Communication and Monitoring System Based on Aviation ARINC825 Bus

According to the requirement of real-time acquisition and monitoring on aeronautical radio incorporated (ARINC) 825 bus multi-channel data and simultaneous information analysis of aircraft parameter information, the author have designed a remote data communication and monitoring system of ARINC825 bus based on LabView software platform of national instrument(NI), which performs the display and storage of the ARINC825 data of multiple different channels in real time, and the interpretation of the data from the original code to the physical meaning of the aircraft through the defined communication protocol. The experimental results show that the system can realize high-reliability data transmission and information sharing between multi-electronic devices as well as multiple systems on the ARINC825 bus, which can parse the data accurately and efficiently and acquire static and dynamic aircraft parameter information. The system has good scalability and versatility.
