The Track Inspection Device adopts digital high-definition imaging and machine vision technology. Through advanced high-resolution, low-noise, and low-distortion image sensors, it achieves high-speed real-time acquisition of line condition data. It features continuous high-definition imaging of rails, fasteners, and ballast bed surfaces, as well as automatic defect recognition and early warning functions. It can be used for real-time detection of line conditions, timely identification of visible defects on rails, fasteners, and ballast beds, guiding maintenance personnel in track upkeep and repair to ensure safe line operation.
