Dsp-based Paver Automatic Leveling Control System

The auto leveling system of the paver plays one of the most important roles in the paver' s technic improving. Through the analyse of the control mode of the paver' s leveling hydraulic system and the work theory of auto leveling controller. And so on, a specific and reasonable strategy has been put out. The paper accomplishes the hardware and software design of the main controller utilizing the DSP and the intelligent sensor utilizing the microchip computer P87C591. In the base of realizing the basic function of auto leveling, the paper aim at solving the problem of the capability for resisting the interferefering signal, in order to solve the problem of the lag domino offect of the hydraulic system, the paper set up the control method "time piece control" that is consult the theory of real-time kernel; Combine the hardware filter and the software filter, eliminate the effect of interferefering signal. Through the experiment, validate the function and the control capability of the controller. Through the study of auto leveling DSP control system, lay the foundation of the ultrasonic auto leveling control system study.
