Problems solved by technology

[0002] The control method of the existing paver leveling instrument is mainly: the paver provides the leveling control power supply, and the leveling instrument independently controls the leveling solenoid valve of the paver; this requires setting the sensitivity of the leveling instrument according to the experience of the operator. The sensitivity setting is higher when the paving operation speed is fast, and the sensitivity setting is lower when the paving operation speed is slow. If the sensitivity setting is inappropriate, it will seriously affect the quality of the construction road surface

Abstract

The invention provides an adaptive control method and a controller for levelling of a paver, and a paver. The adaptive control method comprises the following steps of: determining working condition data of the paver; determining an output signal of a levelling sensor corresponding to the working condition data; according to a preset rule, adaptively acquiring a levelling sensitivity parameter corresponding to the working condition data, wherein the parameter comprises a levelling dead zone section and a proportion control section; and calculating according to the levelling sensitivity parameter and the output signal of the levelling sensor, determining a duty ratio signal, and controlling a levelling ascending solenoid valve or a levelling descending solenoid valve according to the duty ratio signal. The levelling sensitivity parameter corresponding to the working condition data is adaptively acquired, and sensitivity parameters under different paving working conditions are effectively controlled, so that the pavement construction quality is improved and the operating difficulty of the paver is reduced.

Description

technical field [0001] The invention relates to the field of road laying machinery, in particular to an adaptive control method for leveling a paver, a controller and a paver. Background technique [0002] The control method of the existing paver leveling instrument is mainly: the paver provides the leveling control power supply, and the leveling instrument independently controls the leveling solenoid valve of the paver; this requires setting the sensitivity of the leveling instrument according to the experience of the operator. The sensitivity setting is higher when the paving operation speed is fast, and the sensitivity setting is lower when the paving operation speed is slow. If the sensitivity setting is inappropriate, the quality of the construction road surface will be seriously affected. For example, when the sensitivity is set too high, there will be short waves in the longitudinal direction of the road; if the sensitivity is set too low, there will be long waves in ...
