摘　　要：为了提高网络中每个接入点的时间同步性能,将时间触发以太网协议集成到以太网协议中,形成应用于航空网络的时间触发以太网(TTE),可以提高航空设备在实时管理系统中的应用能力。基于SAEAS 6802同步协议和底层时钟同步算法技术,以创建和维护全球统一的航空电子系统,为航空电子系统提供确定性的网络通信。基于时间触发以太网协议,开发了一款带PCIe接口的TTE仿真板,并独立搭建了TTE网络仿真板的通信环境,用于模拟真实的TTE网络环境,模拟真实系统中不同数据流的通信,为网络通信提供参考。In order to improve the time synchronization performance of each access point in the network,the time-triggered Ethernet protocol is integrated into the Ethernet protocol to form a time-triggered Ethernet(TTE)applied to the aviation network,which can improve the application capability of aviation equipment in the real-time management system.Based on the SAEAS6802 synchronization protocol and the underlying clock synchronization algorithm technology,a globally unified avionics system can be created and maintained,providing deterministic network communication of avionics systems.Time-based triggering of the Ethernet protocol,a TTE simulation board with PCIe interface is developed,and the communication environment of the TTE network simulation board is independently built,which is used to simulate the real TTE network environment and the exchange of different data streams in a real system to provide a baseline for the network.
