由体力消耗或精神紧张引起的人体疲劳是制约操作员完成特定任务的功能能力的最重要因素之一。为了保证作业绩效和改善职业健康，本文旨在建立一种定量评估管道作业人员疲劳程度的方法。在实验研究中测量了日本版的Borg 's RPE量表和心脏搏动间隔（RR间隔）。从去趋势波动分析（DFA）中提取Hurst指数（HE）来定义RR区间时间序列的分形结构。结果表明，工作状态下的HE显著高于休息状态。
Human fatigue caused by either physical exertion or mental strain is one of the most significant factors that constrain operator’s functional capability to fulfill specific tasks. To ensure working performance and to improve occupational health, this paper aims to develop a quantitative method to evaluate operator fatigue during conducting pipeline works. A Japanese version of Borg’s Rating of Perceived Exertion (RPE) scale and heart inter-beat intervals (RR interval) are measured in an experiment study. Hurst exponent (HE) is extracted from detrended fluctuation analysis (DFA) to define the fractal structures of RR interval time series. Results show that HE during working condition is significantly higher than during rest condition.
