The invention belongs to the field of engineering safety monitoring, and provides a tower crane safety monitoring method and system based on digital twinning, and the method comprises the steps: building a geometric model of a tower crane through modeling software; constructing a physical model of the tower crane based on the geometric model and the physical attributes of the tower crane; acquiring operation data of the tower crane in real time; calculating the stress of the key position of the tower crane according to the operation data and the physical model, and organizing the stress into a stress time sequence; calculating accumulated fatigue of the key position according to the stress time sequence; and if the accumulated fatigue of the key position exceeds a preset value, carrying out safety early warning. According to the scheme, safety monitoring of the tower crane is efficiently carried out.

    本发明属于工程安全监测领域,提供一种基于数字孪生的塔机安全监测方法及系统,包括:利用建模软件构建塔机的几何模型;基于塔机的几何模型以及物理属性构建塔机的物理模型;实时获取塔机的运行数据;根据所述运行数据以及所述物理模型计算所述塔机关键位置的应力,并将所述应力组织成应力时间序列;根据所述应力时间序列计算所述关键位置的累积疲劳;如果所述关键位置的累积疲劳超过预设值,则进行安全预警。上述方案高效地进行塔机安全监测。
