Intelligent building security device

The invention discloses an intelligent building security and protection device, and relates to the technical field of intelligent buildings, the intelligent building security and protection device comprises a mounting frame, supporting shells are symmetrically and fixedly connected to one side of the mounting frame along a perpendicular bisector, buffer mechanisms are arranged on the inner walls of the supporting shells, each buffer mechanism comprises a supporting rod, and a buffer spring is attached to the outer wall of each supporting rod; supporting blocks are arranged on the outer walls of the two supporting rods, and protective nets are arranged at the bottoms of the supporting blocks. According to the intelligent building security and protection device, when a falling object falls on the surface of the protection net, corners on the two sides of the protection net drive the supporting blocks to extrude the buffer springs through falling impact force, so that the falling force of the falling object is r
