摘　　要：针对道面全时域监测手段的不足,提出了一种基于光栅阵列振动传感的道面车辆监测方法。该方法基于光栅阵列技术,通过将光栅阵列传感光缆布设道面底层,利用光栅阵列解调设备实现车辆振动行驶信息的获取。通过对车辆的行驶振动数据进行理论分析和实验研究,在有效滤波的前提下,可准确获取车辆行驶的轨迹,并进一步测得车辆行驶的速度、位置等信息。此外,通过设计基于图像的车辆跟踪识别算法,极大地消除了恶劣环境的影响,可实现监测路段全时全域的跟踪监测,为公路的智能化探索了一条新的道路。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.
