An automatic leveling control system for jib bridge inspection platform is introduced. The CANopen bus communication is used. The closed-loop control system is used to control the electro-hydraulic proportional valve, and the parameters are adjusted on site so as to achieve the desired leveling effect. Elaborated the concrete realization plan of this system, gives the system realization block diagram and the procedure flow chart. Practice has proved that the automatic leveling control system of the working platform achieves the ideal control precision, the response speed and the stability, the control scheme is simple and easy, and has certain versatility.
