本文研究了TTEthernet在运载火箭控制系统中的应用。首先，提出了下一代运载火箭的通信网络需求。然后，我们从网络通信机制、时钟同步和容错性能的角度介绍了TTEthernet。进一步分析了TTEthernet的应用优势。最后，设计了一种基于TTEthernet的运载火箭双冗余通信网络拓扑，研究了运载火箭发射过程中通信网络的数据流。研究结果不仅可以展示TTEthernet在运载火箭上的探索，也可以为TTEthernet在空间应用领域的研究提供指导。
In the paper, we research on the application of TTEthernet in the launch vehicle control system. Firstly, the communication network requirements of next generation launch vehicle is proposed in this paper. Then, we introduce the TTEthernet in the view of the mechanism of network communication, clock synchronization and fault-tolerant performance. And further, we analyze the application advantages of TTEthernet. Lastly, we design a dual redundant communication network topology for launch vehicle based on TTEthernet, studying the dataflow of the communication network during the process of vehicle launching. The results can not only show the TTEthernet exploration in launch vehicle, but also provide a guideline for TTEthernet research in the field of space application.
