【Abstract】 The communication network in Manned Launch Vehicle was developed for long-range testing,launch and control of launch vehicle,in which hot-standby route and retransmission validation protocol were used to build the information interchange platform with high efficiency and high reliability. On the basis of the system frame design and reliability analysis,applying key technology of the fault diagnosis in waiting-for-lift-off phase and the rocket launch process command,a highly reliable communication network system was implemented. The system was successfully applied to the manned space program. The technology was successfully applied to the optimization of the rocket’s information transmission and application mode. A standard system framework was provided. It can be applied to the system design of future rocket and spacecraft information transmission and application.更多还原
