Research on Vehicle Monitoring Using Pavement Surface Based on Grating Array Vibration Sensing
This paper addresses the limitations of full-time domain monitoring methods for pavement by introducing a road vehicle monitoring approach based on grating array vibration sensing.Grating array vibration sensing utilizes grating array technology,where a grating array sensor optical cable is laid beneath the road surface.Through grating array demodulation equipment,vehicle vibration information is extracted.Theoretical analysis and experimental research on vehicle vibration data reveal that,with effective filtering,the experimental setup can accurately capture vehicle trajectories and ascertain vehicle speed and location.Furthermore,the paper proposes an image-based vehicle tracking and recognition algorithm to mitigate the impact of harsh environmental conditions,enabling comprehensive tracking and monitoring of the entire monitoring section in real-time.This methodology paves the way for advancements in intelligent highway systems.
