摘　　要：本文针对空间太阳望远镜(Space Solar Telescope,简称SST)主光学望远镜控制复杂、数据量大及可靠性要求高等特点,分析了电学系统和中央电子单元的功能,提出了数控分流的策略和分级分布式管控的模型,并建立了基于FPGA和LEON核的可重构设计及容错方案.The Main Optical Telescope （MOT） is a payload of the important solar observing satellite SST with features of complex control, large volume science data and high reliability. According to the requirements of electronic system and central electronic unit,this paper brings forward a strategy to deal with science data and control task separately and builds a distributed model. Reconfigurable design based on FPGA and LEON core and fault tolerant scheme were given.
