A proposal of real-time fatigue state grasp method of high-load activities workers

消防队员在恶劣的条件下工作。疲劳可能成为意外事故发生的因素之一，导致安全管理不足。在消防活动中的物理数据是重要的，以获得客观指标的急性疲劳。为保证消防员的安全，应采用一些客观的急性疲劳指标来代替基于经验的主观判断。提出了一种模拟8层建筑消防实战训练的标准化训练程序，并与18名现役消防员合作，在温湿度控制的气候室中，按照标准化训练程序进行实验。在此基础上，结合体温和RR间期数据频率分析得到的波动指数，开发了表征疲劳状态的逻辑。

Fire fighters are working under severe conditions. Fatigue may become one of the factors of an unwanted accident and cause insufficient safety management of them. Physical data during fire fighting activity are important to derive objective indices of acute fatigue. To secure fire fighters subjective judgment based on experience are to be replaced with some objective indices of acute fatigue. A standardized training procedure was proposed which well simulates the practical fire fighting training in 8 storied building.In cooperation with 18 active firefighters, experiments were carried out in accordance with standardized training procedure in a climate room, which is managed temperature and humidity. Based on the data, the logic representing the fatigue state was developed in combining with the body temperature and the fluctuation index obtained by the frequency analysis of RR interval data.
