随着科学技术的飞速发展,航天发射场测试发射系统的结构越来越复杂,影响航天试验任务装备系统正常运行的因素也急剧增加,使其产生故障或失效的可能性也越大,且故障也呈现日趋复杂化的趋势;以外安系统为例,根据外安系统设备组成及工作原理,研究了基于案例推理和故障树分析相结合的故障诊断方法,为系统指挥决策提供参考信息,有效地提高了航天器在靶场的测试效率。
With the rapid development of science and technology, the structure of the test launch system of the space launch site has become more and more complicated. The factors that affect the normal operation of the space mission test equipment system also increase sharply, making it more likely that the launch or failure will occur, But also tends to be more and more complicated. Taking an external security system as an example, the fault diagnosis method based on case-based reasoning and fault tree analysis is studied according to the composition and working principle of external security system to provide reference information for system command and decision effectively Improve the spacecraft in the shooting range of test efficiency.
