| 摘 要： | 卫星整星测试时系统接口多,供电环境复杂,工作时需要严格按照时序进行开关机控制。文章结合典型故障案例进行了上电时间对单机设计、工作的影响分析,发现2类常见的异常现象:1)上电欠压引起的状态不可确定问题;2)上电时序不合理造成的单机数据异常问题。最后给出实用的排查方法供工程设计人员参考。

| Abstract: | Because of the multiple interfaces and the complex power supply condition, the strict time sequence control is needed when the satellite is being tested. In this paper, the impact of power-up time on the satellite is analyzed combined with typical trouble cases, then two common types of abnormal phenomena caused by it are found:1) the undetermined states caused by the insufficient power supply, 2) the abnormal data caused by the power-up time sequence. Finally, a practical check method is suggested for engineering designers. |
