摘　　要：对于分布式远距离运载火箭测试发射控制系统(简称测发控系统)而言,基于网络的通信系统是整个测发控系统的神经中枢。本文针对测发控系统高可靠性的要求,提出了3种网络拓扑结构并进行了可靠性定量分析,最终确定了"环形交叉"的网络拓扑结构。Regarding the distributed distance test and launch control system of launch vehicle, the communication system based on a network is the nerve centre. In this paper, due to the requirement of the high reliability of test and launch control system, three kinds of network topology are proposed and the ＂circle-cross＂ network topology is finalized according to the quantitative analysis in reliability.
