诸如载人航天器及大型民机等飞行器密闭微环境,随着人员停留时间的延长,舱室空气污染问题已成为危害工作人员生命安全的主要因素,所以迫切需要开展突发不确定污染源定位及散发强度辨识方法研究,以提高主动应对突发污染的能力.提出采用敏感性分析算法实现突发污染源定位及散发强度估计,还分析了不同位置处的传感器可辨识区域,以确定最优传感器布置策略.上述研究能够实现污染源散发特性的快速准确辨识,为主动应对污染事故提供依据.仿真结果证实了该算法的有效性.
諸如載人航天器及大型民機等飛行器密閉微環境,隨著人員停留時間的延長,艙室空氣汙染問題已成為危害工作人員生命安全的主要因素,所以迫切需要開展突髮不確定汙染源定位及散髮彊度辨識方法研究,以提高主動應對突髮汙染的能力.提齣採用敏感性分析算法實現突髮汙染源定位及散髮彊度估計,還分析瞭不同位置處的傳感器可辨識區域,以確定最優傳感器佈置策略.上述研究能夠實現汙染源散髮特性的快速準確辨識,為主動應對汙染事故提供依據.倣真結果證實瞭該算法的有效性.

Along with the prolonging of people's staying time in enclosed environments such as spacecraft, aircraft and so on, air pollution in the cabin has become a main factor which endangers occupants' life safety. Therefore, it's crucial to develop investigation about identification of sudden unknown contaminant source location and strength, which could help improve the ability of enclosed environments to deal with sudden contaminant. This paper presented the sensitivity analysis algorithm which can identify source location and strength. Still more, this paper analyzed the identifiable zone of different sensor placements, and provided the better one. The research above can identify the source emitting characters rapidly and accurately, which provides foundation on replying contaminative accidents. Simulation results have proved the virtues of the novel method.
