In order to research the laser and high-intensity magnetic analysis theory so as to realize the online wire rope detection principle and method, based on the digital high-intensity magnetic wire rope detection technology, corresponding software was applied to realize data record and analysis, and safety assessment report was offered every regular interval, then detection indexes were added so as to enhance the wire rope detection precision. By using advanced laser technology and wire rope diameter contraction, the test was conducted, broken wire of the wire rope was online detected and the diameter contraction data were obtained. After comparison with technical indexes, whether the detected data was up to the standard could be judged. The test results showed: with the aid of the laser and high-intensity magnetic detection technology, both the detection precision and speed obviously enhanced, the life prediction and safety assessment of the wire rope completed online, thus the hidden danger could be predicted in advance, which greatly improved the service safety and economy of wire rope.
