| 摘 要： | 为降低全生命周期成本,提高航天运载器综合竞争力,提出了基于综合电子方案的某型运载器电气系统设计实现方法。首先对该运载器功能需求进行了分析,建立了基于综合电子的系统分布式集成逻辑架构,然后分别就系统任务规划与操作系统分区结构、基于时间触发以太网(TTE)的一体化机内外总线体制以及系统容错处理机制等关键技术及实现途径开展了分析论证。本方案提出的相关软、硬件设计方法有利于实现系统快速集成与系统内资源共享,同时为实现冗余容错控制、在线任务规划等功能提供了便利。

| Abstract: | A design method for electronic system based on integrated electronics is proposed in order to reduce the life cycle cost and improve overall competitiveness of launch vehicle. Distribution-Integrated logic structure of integrated modular avionics is built firstly after analysis of function requirements of the launch vehicle, and then the key technologies and implementation approaches about Time Triggered Ethernet(TTE) bus, task planning , system operation hierarchical structures, and redundant and fault-tolerant control strategy are analyzed. Fast system integration and resources sharing can be realized by the software and hardware framework with online mission planning and redundant fault-tolerant control function. |
