摘要/Abstract

摘要： 为预防建筑工人工作有关肌肉骨骼疾患(WMSDs),提出基于智能手机的建筑工人躯干姿势危险评估方法。以建筑工人WMSDs发病率最高的背部为研究对象,将智能手机作为数据采集工具,利用其内置方向传感器输出数据,计算建筑工人工作时躯干的屈伸、横向弯曲和扭转角度,从而描述当前的躯干姿势;根据ISO11226:2000中给出的静态姿势与保持时间的关系,对当前姿势进行危险评估;通过实验室和现场试验验证该方法的有效性和实用性。结果表明:用该方法能够准确地描述建筑工人的躯干姿势,并评估其危险。

关键词: 建筑工人, 有害姿势, 最大保持时间, 智能手机, 肌肉骨骼疾患(WMSDs), 危险评估

Abstract: For the WMSDs prevention of construction workers,a method was worked out for assessing the risk of construction workers' trunk posture using mobile sensor. The back having a higher prevalence of WMSDs for construction workers was taken as research object. The built-in smartphone orientation sensors was used to collect data utilized to calculate the flexion-extension angle, lateral bending angle and rotation angle of the trunk posture. The risk of posture was assessed according to the relationship between the static angle and the maximum holding time given by ISO11226: 2000. The method was verified by the laboratory and on-site experiments. The results show that the worked out by the authors is effective and applicable to description and assessment of the construction workers' trunk posture.

Key words: construction workers, awkward posture, maximum holding time, smartphone, work-related musculoskeletal disorder (WMSDs), assessment of risk
