Building multi-stage falling safety system

The invention relates to the technical field of public safety, in particular to a building multi-stage falling safety system which comprises a high-altitude deployable safety device, an air bag embedded floor tile module and a dangerous falling visual recognition device. The high-altitude deployable safety devices can be selectively installed layer by layer or installed at intervals of floors, the air bag embedded floor tile module is installed in an outdoor ground area, and the dangerous falling visual recognition devices are evenly distributed and installed on the ground around the building main body; according to the system, the multiple high-altitude extensible safety devices are arranged between the adjacent floors or the spaced floors, so that the system has a multi-stage anti-falling mechanism and effect, the risk of high-altitude falling accidents can be greatly reduced, the risk of high-altitude falling can be found in time through a camera by arranging a dangerous falling visual recognition device,
