Core technical advantages: First, full defect detection, can simultaneously detect external and internal defects of steel wire ropes, identify micro broken wires as small as 0.5mm, with 100% detection coverage and no detection blind spots; Second, AI intelligent recognition, train AI model based on tens of millions of steel wire rope defect samples, automatically identify defect type, location, severity, automatically generate evaluation report and disposal suggestions, no manual interpretation required; Third, online non-stop detection, the detection equipment is installed in the elevator machine room, and the detection can be completed when the elevator is in normal operation, no need to stop the elevator, no need to disassemble the steel wire rope, and does not affect the normal use of the elevator; Fourth, life prediction, through the analysis of steel wire rope wear trend, predict the remaining service life, early warning of scrap risk, and realize preventive maintenance; Fifth, data traceability, the detection data is automatically stored in the elevator safety file, which can be retrieved and traced at any time, in line with the requirements of the supervision department. At present, this technology has been applied to more than 800,000 elevators nationwide, and has been included in the mandatory inspection items of regular elevator inspection in many regions.
