基于案例推理的航天发射场故障诊断系统

Cosmodrome Fault Diagnosis System Based on Case-Based Reasoning

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,space launch structure and field test launch equipment system become more complex.The factors to influence the normal operation of aerospace test equipment system have increased dramatically,which makes the growing possibility of malfunction / failure,and these failures also showed a trend of being increasingly complicated.Outside trajectory measurement and self-destruction system as an example,according to the system composition and working principle of the equipment,a kind of fault diagnosis method that the combination of the case-based reasoning method and fault tree analysis method has been studied.The application of this method provides reference information for the launch command decision,and improves the test efficiency of spacecraft test at launch site.
