Vehicle-mounted steel rail disease monitoring device based on visual analysis and working method thereof

Abstract

The invention discloses a vehicle-mounted steel rail disease monitoring device based on visual analysis and a working method thereof and belongs to the technical field of rail transit steel rail disease health monitoring. The device comprises a data processing and analyzing module, a mileage positioning device, a high-speed camera and a light supplementing lamp, wherein the high-speed camera and the light supplementing lamp are arranged above the steel rail and are connected with the train body of a running train through a suspension device; and the mileage positioning device, the high-speed camera and the light supplementing lamp are respectively connected with the data processing and analyzing module. Based on the principle of visual analysis, the high-speed camera is used for replacing human eyes, so detection efficiency is greatly improved; meanwhile, the device can be arranged below a train body, a special large professional detection vehicle is not needed, problems can be found in time along with advancing of the train, follow-up processing can be carried out, normal train operation cannot be affected, operation and detection are integrated, safety and stability of rail transit are improved, and good application prospects are achieved.

Description

technical field [0001] The invention belongs to the technical field of rail transit rail disease health monitoring, and in particular relates to a vehicle-mounted rail disease monitoring device based on visual analysis and a working method thereof. Background technique [0002] After long-term operation of rail transit, the problem of rail defects has become increasingly prominent. Rail head peeling is a kind of rail damage that often occurs in today's heavy-duty railway transportation. It mainly occurs at the inner fillet of the rail head. The wheel-rail contact stress at the rounded corner is relatively large, and the shear stress at a few millimeters below the rail surface causes shear fatigue on the rail. After cracks occur, the rail surface falls off blocks and pits appear on the rail surface, which further aggravates the unevenness of the wheel-rail surface. Produce more serious high-frequency vibration and noise problems. [0003] At present, the monitoring of track ...

AI Technical Summary

Problems solved by technology

[0003] At present, the monitoring of track operation status is mainly divided into periodic inspection of large professional inspection vehicles, small equipment inspection and manual inspection; periodic inspection of large professional inspection vehicles cannot detect track defects in time; small inspection equipment is flexible, but For the increasingly intensified detection tasks, the detection efficiency is relatively low; manual detection mainly relies on visual observation and experience for disease detection, the detection efficiency is extremely low, and the detection quality varies from person to person
