基于光纤传感的防外力破坏监测热力图数据

基于光纤传感的防外力破坏监测热力图数据集提供了直观的外部振动对光纤产生的扰动信息，覆盖了光纤在不同地质、不同衰减下对不同事件的采集情况。数据集是经由φ-OTDR设备采集的原始数据，在空间上的扩散和时间上的积分构成的热力图，反映了振动信号在时间空间上的变化情况，包括了振动信号的振幅变化、频率变化、运动趋势等信息。这些数据不仅直观反应了光纤附近的振动强度，通过时间和空间上的振动变化情况，还揭示了振源的运动情况和振源产生原因，为预防外部振源对光纤产生破坏性影响提供了有力支持。

The optical fiber sensing-based external force damage prevention monitoring heatmap dataset provides intuitive perturbation information of optical fibers caused by external vibrations, covering the acquisition scenarios of optical fibers under different geological conditions and attenuation levels for various events. The dataset consists of raw data collected by φ-OTDR equipment, and the heatmaps are generated via spatial diffusion and temporal integration of the raw data, which reflect the temporal and spatial variation characteristics of vibration signals, including information such as amplitude changes, frequency changes, and movement trends of the signals. These data not only intuitively reflect the vibration intensity near the optical fiber, but also reveal the movement status and cause of the vibration source through the temporal and spatial variations of vibrations, providing strong support for preventing destructive impacts of external vibration sources on optical fibers.
