摘　　要：太阳辐射监测仪作为某卫星的有效载荷,在轨测量时卫星读取仪器遥测口的遥测信号并打包下传,随后解包判断SIM工作是否正常。因此遥测信号十分重要,在研制阶段的地面模拟在轨飞行环境的试验中,也需要实时采集显示遥测口的遥测信号,以分析环境变化对遥测信号的影响及规律。通过基于DSP的下位机设计和基于VC的上位机编程,实现了遥测信号的采集和实时显示,系统结构简单,图像显示实时,为环境实验阶段仪器状态的判读起到了重要作用。实验证明,系统工作稳定,满足实时采集、实时传输和实时显示的任务要求。The Solar Irradiance Monitor （SIM） is a load of a satellite. On the track the satellite reads the remote sensing interface to get the remote sensing signals and transmit the package to the ground, then judge whether the SIM is normal through analyzing the package. So the remote signals is very important, in order to analyze the effect of the environment to the SIM in the environment experiment of SIM on the ground it is require to sample the remote signals and real--time display. The system includes the down computer designed based on DSP and the upper computer designed based on VC, and can sample the remote signals and real--time display, meets the requirement of the real --time sampling, real--time transmit and real--time display.
