Underground cable external damage prevention monitoring method based on vibration optical fiber

The invention relates to the technical field of underground cable external damage prevention monitoring equipment, in particular to an underground cable external damage prevention monitoring method based on a vibration optical fiber. According to the method, when the vibration optical fiber is installed, it does not need to guarantee that the vibration optical fiber path is the same as the cable path, that is, when the optical fiber is buried on the ground, the burying orientation and angle of the vibration optical fiber do not need to be continuously adjusted, and the construction difficulty is greatly reduced; the vibration optical fiber only needs to be buried in the direction of the string, and the string is a line segment, so that the construction process is much easier. The problem that distributed vibration optical fibers are adopted on a buried underground cable for cable damage monitoring is solved. 本申请涉及地下电缆防外破监测设备技术领域，尤其涉及一种基于振动光纤的地下电缆防外破监测方法。本方法在安装振动光纤时，不需要保证振动光纤路径与电缆路径相同，即在挖掘地面埋设光纤的时候，不需要不断的调整振动光
