description The utility model discloses a hoop displacement early warning device and system and a bent cap. The hoop displacement early warning device comprises a magnetic piece, a first connecting piece is arranged on the magnetic piece, and the magnetic piece is connected to a hoop installed on a pier column through the first connecting piece; a second connecting piece is arranged on the switch piece, the switch piece is connected to the pier column through the second connecting piece, and meanwhile the switch piece is located on the upper side or the lower side of the hoop; the controller is electrically connected with the switch part and is used for generating a control signal according to an on or off signal when the switch part is on or off due to the change of the distance between the switch part and the magnetic part; and the host is in communication connection with the controller and is used for controlling alarm when receiving the control signal. The technical problems that in the capping beam construction proc
