摘要: 为探究人体呼吸参数与管制工作负荷的关系,本文选取27名被试开展模拟管制实验,对不同类型工作负荷下被试的呼吸参数进行采集分析。首先,根据Spearman秩相关系数计算结果,分别获取与脑力和体力管制工作负荷显著相关的呼吸参数。然后,基于有序Logistic模型方法,以显著相关的呼吸参数为自变量,5类不同严重程度的脑力和体力管制工作负荷为因变量,构建脑力负荷和体力负荷严重程度预测模型并进行似然比和拟合优度检验。进一步,绘制ROC(Receiver Operating Characteristic)曲线,检验预测模型的性能;最后,使用交叉表评价方法预测模型的准确率。结果表明:呼吸参数中,呼吸周期与脑力负荷显著相关,呼吸周期、呼吸幅值和吸呼比与体力负荷显著相关。在0.05的显著性水平下,构建的脑力负荷和体力负荷严重程度预测模型拟合效果良好,整体AUC(Area Under Curve)分别为0.679和0.753,模型均具有一定的检测性能。交叉表评价结果表明,模型对脑力和体力负荷中的高负荷状态预测效果最好,准确率分别高达88.9%和83.3%。本文研究结果能够为基于呼吸参数的管制工作负荷监测提供一定参考价值。

Abstract: To investigate the relationship between the human respiratory index and controlled workload, a simulated air traffic control experiment was conducted by the selected 27 subjects to collect and analyze their respiratory parameters under different types of workloads. First, according to the calculation results of Spearman's rank correlation coefficient, the respiratory parameters which are significantly correlated with mental and physical control workloads were obtained. Then, based on the ordered logistic model method with significantly correlated respiratory parameters as independent variables and five graded levels of mental and physical regulatory workload as dependent variables, the prediction models for the severity of mental and physical workload and the likelihood ratio test were constructed and goodness-of-fit tests were carried out. Furthermore, the ROC (Receiver Operating Characteristic) was plotted to evaluate model performance, and finally Confusion Matrix was used to verify the prediction accuracy of model. The results showed that among the respiratory parameters, the respiratory cycle was significantly correlated with mental workload, and the respiratory cycle, respiratory amplitude and inspiration-exhalation ratio were significantly correlated with physical workload. At a significance level of 0.05, the constructed prediction models for mental workload and physical workload severity demonstrated the satisfactory goodness of fit and exhibited certain detection capabilities, with the overall AUC (Area Under Curve) values reaching 0.679 and 0.753 respectively. The evaluation results of Confusion Matrix showed that the prediction model demonstrated optimal performance in identifying high mental and physical workload conditions, achieving highly prediction accuracies of 88.9% and 83.3% respectively. The research results of this article can provide a certain reference value for monitoring control workload based on respiratory parameters.
