Abstract EN
The safety of train operating is seriously menaced by the rail defects, so it is of great significance to inspect rail defects dynamically while the train is operating.
This paper presents a two-dimensional impact reconstruction method to realize the on-line inspection of rail defects.
The proposed method utilizes preprocessing technology to convert time domain vertical vibration signals acquired by wireless sensor network to space signals.
The modern time-frequency analysis method is improved to reconstruct the obtained multisensor information.
Then, the image fusion processing technology based on spectrum threshold processing and node color labeling is proposed to reduce the noise, and blank the periodic impact signal caused by rail joints and locomotive running gear.
This method can convert the aperiodic impact signals caused by rail defects to partial periodic impact signals, and locate the rail defects.
An application indicates that the two-dimensional impact reconstruction method could display the impact caused by rail defects obviously, and is an effective on-line rail defects inspection method.
