ARINC429是目前最常用的一种航空通信总线，它具有简单有效，性能可靠等特性。利用ARINC429总线，飞控系统同各机载设备进行通信，但不同设备上并非都采用ARINC429接口，如卫星接收机采用RS 422总线，且飞控系统ARINC429接口有限。为解决这一问题，提出了基于STM32的航空通信总线切换器设计，方案选取了意法半导体的STM32微控制器，具有高度一体化，低功耗，处理速度快，方便调试与后续开发等优点。

As a common avionics communication bus,ARINC429 has the characteristics of simpleness and high effective-ness and reliable performance. With ARINC429,the flight control system can communicate with other airborne equipments. A design of avionics bus switcher based on STM32 is presented because not all of the equipments have ARINC429 interfaces,for example,the satellite receiver uses RS422 bus,and flight control systems have a limited number of interfaces. In the scheme, STM32 MCU of STMicro is chosen,which has a high degree of integration,low-power consumption and high processing speed, and is easy to debug and develop.
