The invention discloses a platform safety guarantee system for a microsatellite, which mainly comprises a power management and power supply and distribution module, a data interface module, a thermal control management module, a system processor module and a memory module, the power source, the power supply and distribution module, the data interface module and the thermal control management module form a platform core control board in an integrated combination mode, and the platform core control board, the attitude and orbit control expansion board and the measurement and control communication board jointly form a platform core unit. The original scheduling guarantee is converted into direct guarantee based on a platform core guarantee system, the safety of energy, temperature and attitude of a satellite is guaranteed through hardware logic at the bottommost layer under any on-orbit condition, and meanwhile, the normal data channel of whole satellite software reconstruction and the normal storage of key data of whole satellite state recovery can be guaranteed under any condition.

    本发明公开了一种用于微小卫星的平台安全保障系统,该平台安全保障系统主要包括电源管理及供配电模块、数据接口模块、热控管理模块、系统处理器模块和存储器模块,所述电源及供配电模块、数据接口模块和热控管理模块通过集成组合的方式组成平台核心控制板,所述平台核心控制板与姿轨控扩展板、测控通信板共同组成平台核心单元,本发明将替代传统卫星的平台安全保障方式,从以往的调度保障转为基于平台核心保障系统的直接保障,在轨任何情况下,通过最底层的硬件逻辑,保障卫星的能源、温度、姿态的安全性,同时也能够在任何情况下保障整星软件重构的数据通道正常,整星状态恢复的关键数据存储正常。
