The invention discloses an intelligent global monitoring and alarming method for a construction scaffold, and the method comprises the following steps: building a scaffold numerical model and a solid model, and analyzing a vibration characteristic change rule after the scaffold is damaged; positioning a construction scaffold damage position by using a model-free time domain damage identification method of structure acceleration response high-order moment; analyzing the influence of the stress, strain, inclination angle and the like of the rod piece obtained at the limited measuring points on the overall stress and stability of the scaffold by using a neural network technology; a monitoring alarm device is installed at the position where the stress influence of the scaffold is large, and the monitoring alarm device recognizes a vibration signal of the scaffold and sends out a corresponding alarm signal. According to the invention, the construction scaffold damage can be identified and positioned, the damage re
