目的 对航空制造业装配操作者的疲劳检测方法进行研究，并对疲劳监测设备提出设计策略。方法 以人为中心的设计概念为基础，运用实证法，通过对新手操作者和熟练操作者的肌电信号和主观疲劳程度进行采集，整体地分析生理和主观评价的数据，对操作者的疲劳进行评估。结果 得出肌电信号的特征值随着人员的疲劳而规律性地变化，其中RMS值(均方根值)和FInsm5值(由Dimitrov提出的新频域参数)与主观评价表现出显著的相关性;新手操作者与熟练操作者的肌电信号也出现差异。结论 结合RMS值和FInsm5值的联合频谱分析，提出一个评估肌肉疲劳的模型，包括3种肌肉状态:肌肉激活、过渡到疲劳、疲劳到精疲力竭;提出将主观评价标准融入疲劳检测系统的方法;分析航空制造业装配操作者疲劳监测设备的设计策略，包括:可穿戴设备、肌肉疲劳模型的应用策略、反馈数据形式。最后根据设计策略对一款可穿戴设备的人机交互进行了设计应用探索。

In aviation manufacturing industry,fatigue is a common problem among operators. In order to monitor operators's muscle fatigue, sEMG signal and self-perceived fatigue level are collected between novice and skilled operators. The collected data are further analyzed. It is found that a few sEMG features indicated directional changes with the increase of dynamic muscle fatigue. Spearman correlation analysis indicates that Borg ratings have strong correlations with RMS and FInsm5 slopes. Significant differences in the sEMG signals between novice and skilled operators are found. Combined with experimental results, a model is proposed for muscle fatigue assessment. Furthermore, design implications to guide fatigue monitoring devices are discussed for aviation manufacturing workers:design of wearable device, how to apply the proposed model to assess muscle fatigue, and the design of the feedback signal. At last, the design and application of a wearable device for human-computer interaction in this context is explored.
