Abstract

The invention discloses a construction site safety early warning method and system based on a BIM model. The method includes the following steps of establishing the BIM three-dimensional model, establishing coordinate points for dangerous source feature positions, importing the coordinate points into the three-dimensional model, updating feature coordinate points in real time according to the dangerous source information changes provided by site safety officers, judging whether constructors enter a dangerous area or not according to sensor safety helmets of the constructors, conducting dangerous source prompting on the constructors entering the dangerous source area through the safety helmets, transmitting signals back to a monitoring center and site safety managers, supervising the workers entering the dangerous source area in real time by the managers in the monitoring center, and supervising constructors nearby the dangerous source by the site safety managers so as to ensure the safety construction of the constructors. By means of the construction site safety early warning system, through the BIM three-dimensional model, the changes of the site dangerous source are responded toeffectively in time, and dual protection is conducted on the constructors entering the dangerous source area, and guarantees are provided for safety construction.

Description

【Technical field】 [0001] The invention relates to the field of building construction safety early warning, in particular to a large-scale construction project with numerous hazard sources and a BIM model-based building construction site safety early warning system 【Background technique】 [0002] In the field of construction, the occurrence of accidents is always a problem that needs to be solved urgently. Due to the complex situation on the construction site and numerous sources of danger, most construction workers have not engaged in formal safety education, resulting in frequent safety accidents, which will bring heavy losses and a series of chain reactions. In the existing technology, the control of hazards is limited to some signs and fences, and sometimes even the signs are missing and the fences are damaged, which greatly threatens the lives of personnel on site. There is also a sign prompt, but due to the concentration of work, the danger sign is not noticed, resulti...
