Concrete vibrating rod positioning method based on optical fiber sensing

The invention discloses a concrete vibrating rod positioning method based on optical fiber sensing. The method comprises the following steps that a sensing optical fiber is laid in a concrete pouringarea, a plurality of vibration detection points are assigned to the sensing optical fiber in advance, and position coordinates of the vibration detection points are recorded; amplitude data of each vibration detection point are obtained in real time through the sensing optical fiber; the vibration detection point with the maximum amplitude in the obtained amplitude data is the maximum amplitude point, and whether the maximum amplitude point is an effective peak point or not is judged; and the position of a vibrating rod is located in an area with the effective peak point as the circle center and r as the radius, wherein r is a preset value. According to the technical scheme, the vibrating position of the vibrating rod in the concrete construction process can be monitored, concrete vibrating operation can be standa
