Abstract

The invention provides a paver as well as a control method, device and system thereof which are used for solving the problems of insufficient compactness and flatness of the formed pavement under the condition that aggregates can not support a screed of the paver in the prior art. The method comprises: in the working process of the paver, when a leveling cylinder of the paver moves upwards, the included angle between a sensing arm of a leveling instrument of the paver and the vertical direction is increased and the compensated lift pressure increment of a lift cylinder is computed according to the difference between the current displacement of the leveling cylinder and the displacement of the leveling cylinder at the time of recent stabilization and the difference between the included angle and the predetermined setting value of the included angle; and the compensated lift pressure of the lift cylinder is increased according to the compensated lift pressure increment so as to control the lift cylinder of the paver to move upwards. By utilizing the technical scheme of the invention, the paver and the control method, device and system are beneficial to improvement of the compactness and flatness of the formed pavement.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a paver and its control method, control device and control system. Background technique [0002] Paver is a machine that evenly spreads asphalt mixture on the road base, and performs preliminary vibration and leveling. The screed of the paver is the main component for the preliminary vibration and leveling of the road surface. When the aggregate can fully support the weight of the screed, the pulling force of the lifting cylinder is equal to 0, and the flatness of the formed road surface is adjusted by the leveling cylinder. The specific actions are as follows: When the screed does not move up and down, it can be considered that the screed is The vertical direction is in a balanced state, that is, the weight of the screed and the supporting force of the aggregate reach a balanced state; when there is a pit in the roadbed, the leveling cylinder sinks, the elevation ...
