The first magnet part1311and the second magnet part1312attached to the yokes1330generate a magnetic field to thus form the main magnetic flux path in which the setting section between the first magnet part1311and the second magnet part1312is included in the axial direction of the wire rope so that the magnetic flux leakage of the wire rope can be measured by the hall sensor part1320.

In this case, the hall sensor part1320serves to detect the magnetic flux leakage of the wire rope on the main magnetic flux path if the wire rope is magnetized by the magnet part1310having the first magnet part1311and the second magnet part1312.

If a damaged portion such as disconnection, diameter reduction, wear, kink, bending, and the like is generated on the wire rope, the hall sensor part1320detects the magnetic flux leakage generated from the damaged portion of the wire rope.

The detected signal of the hall sensor part1320is analyzed in real time to learn the waveform of magnetic flux leakage data, and accordingly, it is determined that what kind of defect is generated from the damaged portion of the wire rope, thereby producing a safety diagnosis result for the wire rope.

In the process of producing the safety diagnosis result, the defect of the wire rope is determined using deep learning, and the produced safety diagnosis result is transmitted to a user terminal in real time.

Accordingly, the safety diagnosis result of the wire rope can be checked in real time by a user, thereby preventing the occurrence of safety accidents.

In this case, one magnet of the first magnet part1311, one magnet of the second magnet part1312, and a plurality of hall sensors of the hall sensor part1320are arranged on each straight yoke1333, so that the straight yokes1333surround the through hole and thus face the center of the wire rope.

The sensor1300having the yokes1330is configured to allow the yokes1330to be coupled to the shape of the cylinder inside the body1000to provide the through hole formed on the center thereof, so that the wire rope passes through the through hole.

The magnets of the magnet part1310and the first yoke1331and the second yoke1332or the plurality of straight yokes1333of the yokes1330may be freely changed into other shapes.

The wire rope diagnostic device1000according to the present invention may be varied in configuration, but it operates under a main principle in which the magnetic flux generated from the magnets of the first magnet part1311and the second magnet part1312attached to the yokes1330is measured by the hall sensors located between the first magnet part1311and the second magnet part1312and the waveform of the magnetic flux leakage data is thus analyzed to produce the safety diagnosis result of the wire rope.

In this case, the hall sensor part1320includes the plurality of hall sensors located between the first magnet part1311and the second magnet part1312(for example, at a center therebetween) to detect the magnetic flux leakage generated from the wire rope, and the FPCBs1340are disposed between the plurality of hall sensors and one or more yokes1330.
