Elevator security check early-warning system based on cloud computing

The utility model discloses an elevator security check early-warning system based on cloud computing. The elevator security check early-warning system based on cloud computing comprises a steel wire rope damage detector and a server. The steel wire rope damage detector comprises a first permanent magnet, a second permanent magnet, an armature and a magnetic-field measurement element, wherein the north pole of the first permanent magnet is connected with the armature, and the south pole of the second permanent magnet is connected with the armature. When detection is carried out, a steel wire rope to be detected is placed below the first permanent magnet and the second permanent magnet so that an excitation loop can be formed by the steel wire rope, the armature, the first permanent magnet, the second permanent magnet and the air. The magnetic-field measurement element is used for obtaining data of a leakage magnetic field of the excitation loop, and transmitting the data of the leakage magnetic field to the se
