The safety early warning information list is determined according to the target monitoring construction project information, and is matched with the monitoring construction project, and the risk information list possibly influencing construction safety in the construction process is provided. The safety early warning information list comprises safety early warning classification information and safety early warning parameter information. The safety early warning classification information is early warning information obtained by classifying the early warning information according to different categories which affect construction safety. The safety early warning parameter features are features for describing the conditions which are shown when various risk factors in the safety early warning information easily cause potential safety hazards, such as in the construction process, operators should wear safety helmets on construction sites in real time, and the safety early warning parameter features are that the constructors acquired through the image acquisition device do not wear the safety helmets, and production safety accidents are easily caused at the moment.
