Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0012] The control method of the walking system of the paver of the present invention is: the speed of the left motor is compared with the given speed value of the left motor as a feedback value, and the speed of the right motor is compared with the given speed value of the right motor as a feedback value. Compare, and independently control the speed of the left and right motors through the PID regulator to form a core loop; use the speed difference of the left and right motors as the feedback amount to track 0 as the goal, and control the amount formed by the speed difference PID regulator to one of them The speed of the motor is adjusted to form a speed difference tracking correction loop; the accumulated value of the speed difference between the left and right motors, that is, the left and right displacement difference, is used as t...

Abstract

The control method for walking system of spreader includes feeding the rotation speeds of both right and left motor for comparison with the given values, and controlling the rotation speeds via a PID regulator to form a core loop; feeding the speed difference of the right motor and left motor to trace zero target and controlling the speed of one motor via a speed difference PID regulator to constitute a speed difference tracing correction loop; and feeding the accumulated speed difference of the right motor and left motor to trace zero target and further regulate the speed in the speed difference tracing correction loop via a displacement difference PID regulator to form a displacement difference tracing correction loop. All the core loop, the speed difference tracing correction loop and the displacement difference tracing correction loop constitute one closed-loop control system for the walking system of spreader. The present invention has high operation comfortability and high construction quality.

Description

technical field [0001] The present invention mainly relates to the field of paver, in particular to a control method and device for the walking system of the paver. 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 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 deceleration of the engine, etc., and ensures the paving The speed is constant, so that the flatness and compactness of the pavement are greatly improved. Driving control technology is one of the cores of paver control technology. The national standard GB / T16277 "Asphalt Concrete Paver" stipulates the straight-line running performance of crawler-type paver: the deviation of crawler-type paver in straight-line runni...
