Description

technical field [0001] The present invention mainly relates to the field of paver, in particular to a paver travel control device and control method. Background technique [0002] At present, asphalt paver generally adopts a hydraulic system driven by double pumps and double motors and crawler. The system is controlled by an electronic constant speed control system with PLC as the core, which eliminates the change of driving speed caused by many factors such as the load change of the paver driving propulsion system, the unevenness of material feeding, the engine deceleration, etc., ensuring The speed of the paver is constant, so that the flatness and compactness of the pavement are greatly improved. Travel speed control is one of the cores of paver technology. The national standard GB / T16277-2008 "Asphalt Concrete Paver" stipulates the straight-line running performance of the crawler-type paver: the deviation of the straight-line running of the crawler-type paver should no...
