The vibrating point position control system synchronously records the point position information of the already vibrated and not vibrated points, automatically calculates the control parameters of the walking control system, the moving control system and the lifting control system according to the coordinate values of the vibrating point positions, and then transmits the control parameters into the corresponding control systems.
5. The construction method of the box girder bottom plate concrete vibrating device according to claim 1, wherein the method is: S1, preparation before vibrating: the box girder bottom plate (9) and the box girder web plate (10) are laid with inner formworks (11), and two ground rail type steels (1) are laid on the inner formworks (11); S2, establishing a coordinate system and positioning the frame body (4): taking the end of one of the ground rail type steels (1) as the origin of the coordinate system, the servo motor assembly (3), the moving motor assembly (503) and the servo cylinder (505) are zeroed, and the coordinates of the vibrating holes (1103) from the first row to the last row are calibrated according to the overall device zero attitude; S3, according to the coordinates of the first row of vibrating holes (1103), the control parameters of the corresponding servo motor assembly (3), moving motor assembly (503) and servo cylinder (505) are calculated; S4, according to the control parameters, the servo motor assembly (3) is controlled to drive the frame body (4) to walk to the position corresponding to the first row of working point positions; S5, according to the control parameters, the moving motor assembly (503) is controlled to drive the vibrating device (5) to move above the position corresponding to the first row of working point positions; S6, the vibrator (507) and the servo cylinder (505) are started, the servo cylinder (505) is controlled to act according to the control parameters, and then the vibrating rod (5073) is driven to insert into the vibrating hole (1103) of the first row of working holes to vibrate the box girder bottom plate (9); S7, after the first row of working holes are vibrated, the vibrator (507) is turned off, the servo cylinder (505) is zeroed, and the moving motor assembly (503) is zeroed; S8, repeat S3-S7 to successively vibrate the second row to the last row of vibrating holes (1103).
