Interface Design of ARINC 429 Bus Communication

随着机载电子设备向标准化、综合化发展 ,航空数字数据传输系统的设计越来越受关注 ,目前广泛采用ARINC42 9总线作为航空电子系统间信息传输的标准。文章介绍了两种总线接口芯片EF44 42、HS - 32 82 ,以及实现ARINC42

With the development of electronic devices towards standardization and synthesis, the design of the aeronautical digital data transfer system is paid more and more attention, ARINC 429 bus is adopted as a communication standard of avionics system. In this paper, EF4442 and HS-3282 are introduced, which are bus interface circuits, and the interface circuits are designed to accomplish data transfer via ARINC 429 bus.
