On the traditional vertical platform, the supply tank of the hydraulic leg usually shares a common fuel tank with the vertical fuel tank, which not only increases the difficulty of the pipeline layout, but also increases the probability of failure. To solve this problem, The author designed a direct-drive hydraulic leveling system based on LabView. The control software generated by LabView is used to collect and analyze the various sensor parameters of the device, and output control signals to the servo driver for leveling, and the height adjustment function is added, and the platform can be leveled at different ground heights. . The actual verification of the scheme shows that the scheme is feasible, the pipeline is simple, the energy consumption is reduced, and the time for leveling is not increased or even shortened to a certain extent, and the precision can also meet the requirements.
