ARINC429总线在ADS—B系统中的设计

ARINC429总线技术因其结构简单、性能稳定、抗干扰性强、可靠性高等优势，广泛应用于飞机中的数字传输。ADS—B（广播式自动相关监视）是近几年发展起来的用于空中交通管理的有效手段，实现ARINC429总线在ADS—B系统中的应用，可有效促进航空系统数字总线技术的发展。本设计通过设计系统架构、自定义协议等手段，不仅实现了ADS—B信息格式和ARINC429信息格式相互转换的问题，而且很好地将这种转换过程嵌入到ADS—B系统中，具有通用性强、可移植性好、设计成本低等优势。仿真表明．该设计方法正确有效．具有一定的实用价值。

Design of ARINC429 Bus in ADS_B System

The technology of ARINC429 bus is widely used in digital transmission of aircrafts because of its advan- tages like simple structure, stable performance, strong anti-interference and high reliability. ADS B （automatic de- pendent surveillance-broadcast） is an effective way developed application of ARINC429 bus in ADS B can be implemented; al bus technology in air navigation system. By means of in recent years for air traffic management, by which and this can effectively promote development of digit- designing system architecture and self-defining protocol, problem of converting information format between ADS_B and ARINC429 can not only be solved, but also conver- sion process can be made to be embedded into ADS_B system. This design has good advantages like strong versatili- ty, good portability and low cost. The simulation results indicate that this design method is correct and effective, and has a certain practical value.
