| 摘 要： | 诸如载人航天器、潜艇及地下涵洞等有限空间，由于空间小、密闭性强、人员活动频繁，应对突发污染能力差，当发生突发污染事故，直接影响密闭空间内人员的身体健康和生命安全，亟需发展一种可行的突发污染源辨识方法，提高上述密闭环境应对突发污染事故的能力。针对三维密闭空间内的持续污染源，提出一种基于多位置假设的突发污染源定位方法，利用单传感器的观测数据实现三维空间内突发持续污染源辨识；为了提高起始污染浓度感知速度和突发持续污染源定位精度，同时提出采用单边U检测方法进行污染感知；另外针对影响定位的主要因素进行仿真分析。本项研究能够为三维密闭空间内突发持续污染控制提供有效依据。

| Abstract: | It is hard for confined space such as manned spacecraft, submarine and underground culvert to handle the accidental pollution well due to their small space, tight closure and high occupant density characters. Once the pollution happens, it threatens people’s health and life badly. Therefore, it becomes more and more important to develop a feasible contaminant identification method to improve the pollution control ability. The Identification method based on multiple position assumption is proposed in this paper, and a single sensor is used to identify the contaminant in three dimensional space. In order to improve the rapidity and accuracy of the contaminant detection and source location, one tailed U test is used to detect the pollution. Otherwise, some simulations are used to analyze the factors influencing source location. This novel study can provide useful basis for the control of accidental continued contaminant in three dimensional enclosed space. |
