数据综合系统(Data integrated system,DIS)作为星上电子系统和信息管理的核心,在卫星研制和运行管理中,起着非常重要的作用。根据“天巡一号”(NHTX-1)微小卫星的任务需求,对数据综合系统进行硬件及软件设计。着重描述了VxWorks操作系统的使用、整星安全模式、计算机板故障监测和计算机板主备份自主切换等关键技术及创新设计。另外对卫星在轨期间数据综合系统的运行情况进行统计分析,结果表明该系统工作稳定,功能性能指标均满足设计要求。
Data Integrated System (DIS), as the core of electronic system and information management on satellite, plays a very important role in satellite development and operation management. According to the mission requirements of the “small satellite” NHTX-1, the hardware and software design of the integrated data system was carried out. The key technologies and innovative designs such as the use of the VxWorks operating system, the whole-satellite security mode, the monitoring of the failure of the computer board, and the autonomous switching of the main backup of the computer board are mainly described. In addition, the statistical analysis of the operation of the integrated system of data during the orbit of the satellite shows that the system is stable in operation and all the functional performance indexes meet the design requirements.
