Abstract
In order to improve the leveling precision and reduce the leveling time of the vehicle asphalt cement mortar mixing platform, the automatic leveling system was developed based on PLC. The leveling problem of the system turns into predictive controlling to the geometric height difference between the each point and the highest point based on the mathematical relationship between the slant angles and the leg elongations to realize the control of three legs moving together. The results showed that the leveling accuracy of the system reaches ±0.3° and the leveling time is less than 6 s, realized the mortar vehicle mixing platform fast automatic leveling.
