With the development of avionics systems, Avionics Digital Video Bus (ARINC 818) and Digital Information Transmission System (Arinc429) have become a new generation of aviation video transmission and communication bus standard respectively. Aiming at the characteristics of ARINC 818 and Arinc429, an aeronautical digital video and communication bus processing system is designed. First, the ARINC 818 aviation video transmission bus and the Arinc429 communication bus standard are introduced. Then, the design principles of the aeronautical digital video and communication bus processing system are described according to this standard, and the design scheme of each system component is introduced in detail. Finally, build a hardware test platform for testing and verification. The system development follows an integrated and modular design, with the Application Processing Unit (APU) main processor and Field Programmable Gate Array (FPGA) as the core, which realizes the superposition of 1-channel input ARINC 818 video with internally generated characters, and then outputs 1-channel ARINC 818 to the function displayed on the display. At the same time, it supports 7-channel Electronic Industries Association-422 (EIA-422) and 4-channel Arinc429 bus communication. In addition, the system supports the processing of 22 input discrete quantities and 7 input analog quantities. The design has been successfully used in a certain type of aircraft display control management system.
