Non-threatening signal identification method and device, electronic equipment and storage medium

The invention discloses a non-threatening signal identification method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring an optical fiber vibration sensing signal; extracting a fluctuation characteristic value of the vibration sensing signal; judging whether the fluctuation characteristic value exceeds a preset fluctuation threshold value or not, and judging whether the sensing signal has regularity or not when the fluctuation characteristic value exceeds the preset fluctuation threshold value; if the sensing signals have regularity, determining the range of an area where the sensing signals are located, collecting vibration sensing signals in the area range, and determining a vibration center according to the vibration sensing signals; and identifying whether the vibration sensing signal is a non-threatening signal according to the position change of the vibration center. According to the method, destructive digging behaviors and non-destructive farmin
