TTE/TTP技术在航天器中的应用分析

摘要

The basic principle of the TTE/TTP technology is introduced,as the advantages such as time certainty, network conflict reducing compared with event triggered network are explored. The key technology including time scheduling table design, time synchronization and dynamic adjustment of the schedule is proposed towards the application of the TTE/TTP technology with the spacecraft. A feasible solution of the TTE/TTP technology with the spacecraft is clarified to meet the needs of high reliability, strong real time and time certainty of the future development of the spacecraft.%介绍了TTE/TTP技术的基本原理,分析了时间触发网络相对传统网络在时间确定性、减少网络冲突等方面的优势,结合航天飞行器的实际需求,提出了时间调度表设计、时间同步及时间调度表动态调整等方面的关键技术,为实现时间确定性网络技术在航天飞行器上的应用提供了可行的实施方案,从而满足航天飞行器强实时、高可靠、时间确定性等方面的需求,以支撑新型航天器发展.
