摘要
航空电子全双工交换以太网(AFDX)通信端口作为AFDX端系统提供给应用程序的接口,对于AFDX网络消息的传递有着重要的作用。针对AFDX端系统仿真接口板卡的AFDX协议栈在板上实现的特点,提出了一种满足AFDX协议的通信端口的实现方法。端口在端系统驱动中通过加载配置,创建端口、端口发送/接收3个步骤实现,经过应用程序测试验证了其正确性和可靠性。
As an interface the avionics full-duplex switched Ethernet (AFDX) end-system provide to applica- tion program, AFDX communication ports play an important role in AFDX network information transmission. Aiming at the AFDX protocol stack onboard implementation in AFDX end-system interface card, an approach to implement the communication ports is proposed, which are confirmed by three basic steps: loading configu- ration, creating ports and port sending/receiving to meets AFDX protocol. After the application test, communi- cation ports can communicate correctly and effectively.
