The Design of High Availability Hot Plug ARINC429 Card Based on CPCI Bus

Through the research of CPCI hot plug and avionics data bus ARINC429, this paper analyzes and proposes the improvement direction needed to support the high availability hot plug for ARINC429 in CPCI. In addition, this paper also designed the high availability hot plug ARINC429-CPCI board in practice, and provided the necessary support from hardware and software to achieve the target functions. This paper also summarizes the relevant theory and design experience for the application of high availability hot plug technology in aeronautical measurement and control systems.
