Abstract

The invention discloses a system for detecting surface defects of steel rails based on an intelligent trolley. The system comprises the intelligent trolley and an upper computer. The intelligent trolley comprises an image acquisition device, a communication module, a motor driving device and a control device, the image acquisition device, the communication module and the motor driving device are respectively connected with the control device, and the intelligent trolley is communicated with the upper computer via the communication module. The system has the advantages that the traditional manual inspection for steel rail defects is changed, the intelligent trolley and the upper computer are combined with each other to accurately acquire defect data of the steel rails, errors due to human factors can be effectively prevented, the system is high in accuracy, the detection speed can be increased, the labor intensity can be relieved for workers, the detection cost can be saved while the railway line safety is guaranteed, and the line maintenance efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of railway safety protection and detection, in particular to a rail surface defect detection system and method. Background technique [0002] At present, with the increase of rail transit speed, more and more attention has been paid to the on-line quality monitoring technology of rails. The development direction and trend of rail transit are high speed, heavy load and high density. How to ensure the safety of train driving has become the primary issue. As the most basic part of the track, the steel rail directly affects the safety of train running. Therefore, how to ensure the quality of the online status of the rails has become a difficult task for the railway engineering department. [0003] The high-speed, heavy-load, and high-density operation of trains brings great convenience to the lives of the people, but at the same time, the damage to the rails is also increased, and the possibility of cracks and...
