AI Technical Summary

Technical Problem

Railway rails are prone to fatigue cracks and fractures during long-term use. Current technology makes it difficult to continuously inspect rails, making it difficult to prevent safety hazards.

Method used

Design an inspection vehicle for railway track inspection, equipped with an image acquisition device and an ultrasonic flaw detection mechanism. The vehicle travels on the track to conduct all-round inspection. Combined with elastic connection components and ultrasonic flaw detection mechanism, it ensures continuous inspection of the rails and timely detection of potential defects.

Benefits of technology

It enables continuous inspection of railway tracks, timely detection of potential defects in the rails, prevention of major accidents such as derailment and service disruptions, and ensures the safety of railway transportation.
