摘要:

随着电子技术的发展,电子元器件的体积越来越小,处理器的运算能力越来越强,存储器的容量越来越大,总线的传输速率越来越高,电子设备的集成度越来越高,成本越来越低;在这样的背景下,航天器电气综合系统设计理念也在与时俱进,为降低电气系统体积重量和功耗,以提高航天器的任务能力,同时为加快研制进度,降低研制成本,迫切需要开展新型航天器电气综合一体化架构研究,文章主要对比国外航空航天领域飞行器先进电气综合系统架构,分析了目前国内航天器电气系统综合设计中存在的缺陷和弊端,结合我国未来新型航天器对电气综合系统的需求,提出了我国新一代航天器电气综合系统一体化设计的基本原则,并对系统软硬件体系架构及具体的功能实现方式进行了初步的设想。

Abstract:

With the development of electronic technology, the volume of electronic components is getting smaller and smaller,the computing power of the processor is becoming more and more powerful,the capacity of the memory is growing,the transmission rate of the bus is getting higher and higher,electronic devices are becoming more and more integrated,the cost is getting lower and lower. Under such background,the design concept of the electrical system design of the spacecraft is also advancing with the times,to reduce the volume weight and power consumption of the electrical system,in order to improve the spacecraft's mission capability,at the same time to speed up the development of the progress,reduce development costs,an urgent need to develop a new type of electronic integrated structure of spacecraft. In this article,compared with the advanced international electrical system architectures,analyzed the disadvantages of internal electrical system architectures on the aviation and spaceflight.To meet the need of new spacecraft electrical system,the integrative design base principle of new spacecraft electrical system in China is presented.Also,the software and hardware architecture and the realizing method of functions are assumed.
