基于肌电信号的人体高处坠落过程分析与研究

Analysis and Research on the Falling Process of Human at High Altitude Based on EMG Signal

针对高处坠落过程中人体受安全带保护全身各部位受理情况复杂难以测量的问题,研制了便携式可穿戴的智能肌电信号采集服。利用该专业设备,对不同年龄、不同体型的作业人员进行了1 m和2 m坠落距离下人体肌电信号的采集,对人体各部位在坠落过程中的所受影响进行了分析,基本确定了易受伤部位及受伤程度,对后续安全带的改进提供了强有力的技术支撑,同时也为高处作业防护技术的提升提供了重要的理论基础。

A portable and wearable smart electromyography(EMG)signal acquisition suit was developed to deal with the complex and difficult measurement of human body’s acceptance in various parts of the body protected by seat belts during high fall.Using this professional equipment,the human EMG signals of workers of different ages and shapes were collected at 1 m and 2 m falling distance,and the impact of various parts of the human body on the falling process was analyzed.The vulnerable parts and the degree of injury were basically determined,which provided strong technical support for the improvement of the subsequent seat belt,and also provided high-altitude operation protection technology.Promotion provides an important theoretical basis.
