Due to the complex operation environment and diverse risk factors at construction sites

the traditional safety management model often faces problems such as delayed response and extensive control. This paper focuses on the application of smart construction sites in this field

first analyzes the core structure of the perception layer and analysis decision-making layer technologies in smart construction sites

and then discusses the specific application paths from three dimensions: precise personnel management and control

coordinated security of equipment and environment

and closed-loop management of the entire construction process. The research shows that smart construction sites can realize early identification and efficient disposal of safety risks through technology integration

significantly improve the overall efficiency of safety management at construction sites

and provide technical support for the safe development of the industry.​
