| 摘 要： | 对高速铁路司机行车前疲劳状态进行检测,可预防疲劳驾驶,保障行车安全。为此,设计开发了高铁司机行车前疲劳检测系统。检测了高铁司机的心率变异性、闪光融合频率、血氧、血压、呼吸、体温等心理、生理指标,并调查主观疲劳程度和出乘前一晚睡眠时间,获得了180人的有效数据。用统计产品与服务解决方案(SPSS)进行因子分析,计算出综合疲劳指数,并验证综合疲劳检测模型的拟合度。采用K-均值聚类分析和CART决策树算法,将综合疲劳指数分为4个等级。系统可在5 min内完成全部检测,即刻出报告,可防止高铁司机疲劳驾驶,并促使他们出乘前注意休息。系统附加提供按摩放松操作和保健知识推送,同时建立个人档案,以便长期监测司机疲劳状况。

| Abstract: | Testing the fatigue state of high-speed railway drivers before driving can prevent fatigue driving and ensure driving safety. Therefore, this article designed and developed pre-driving fatigue detection system for high-speed railway drivers. In this study, the heart rate variability, flash fusion frequency, blood oxygen, blood pressure, breathing, body temperature and other psychological and physiological indicators of high-speed railway drivers were examined, subjective fatigue and sleep time the night before departure were investigated, and 180 valid data were obtained. The factor analysis was carried out using statistical product and service solution software. The comprehensive fatigue index was calculated by factor analysis with statistical product and service solution software, and the fitness of the integrated fatigue detection model was verified. By K-means clustering analysis and CART decision tree algorithm, the fatigue index was categorized into 4 levels. The pre-driving fatigue detection system for high-speed railway drivers can complete all the tests within 5 minutes and report immediately, which can prevent high-speed railway drivers from driving fatigued and urge them to take a rest before leaving. The system additionally provides massage relaxation operation and health knowledge push, while establishing personal files for long-term monitoring of driver fatigue. |
