Automatic paver leveling control system and automatic paver leveling control method

Abstract

The invention discloses an automatic paver leveling control system and an automatic paver leveling control method. The control system comprises a central processing unit, and a leveling system, a walking system and a screed system which are respectively connected to the central processing unit, wherein the central processing unit is also connected with a leveling solenoid valve which is controlled to ascend or descend; the leveling system, the walking system and the screed system are provided with sensors for acquiring operating condition data; the central processing unit acquires the current operating condition data provided by the sensors through a communication line, refers to the corresponding relationship between the preset operating parameters and the leveling adjustment mode and determines the leveling adjustment mode corresponding to the current operating parameters. According to the control method for the system, the leveling sensitivity parameters corresponding to operating condition data are acquired in a self-adaption manner, so that the sensitivity parameters under different paving operation conditions are effectively controlled, the pavement construction quality is improved, and the operation difficulty of a paver is lowered.

Description

technical field [0001] The invention relates to the technology in the field of road construction equipment, in particular to an automatic leveling control system and method for a paver. Background technique [0002] Paver is a kind of construction equipment mainly used for paving various materials on the base course and surface course of the expressway. In recent years, due to the increasing number of road construction projects, and the engineering construction units have higher and higher requirements for the smoothness of the road surface. [0003] According to the analysis, the factors affecting the leveling of paver can be summarized into the following aspects: 1. The error between the roadbed and the benchmark, that is, the height change of the roadbed; 2. The speed change of paving; 3. The change of material temperature; 4. 1. The change of material level height in the distribution tank; 5. The change of vibrating frequency. Changes in these factors can destroy the f...
