In order to reduce and prevent the accidents of the formwork support frame from falling,the management level of safety warning should be improved. On the basis of the identification and analysis of the hazard source of the accident caused by the falling of the frame body,the dangerous area and the warning grade are divided according to the different falling objects of the frame body. At the same time,based on the requirement analysis of early warning management information,the system framework including information collection layer,network layer,interaction layer and application layer is constructed. Finally,the flow chart of early warning and management system of formwork support system is constructed based on building information model and radio frequency identification technology. The results show that the system can collect,locate and track hazard information. The automatic identification and warning of the dangerous area can realize the visual analysis and intelligent early warning of the fall accident of the person who put up the frame and the construction personnel on the frame.
