Method, equipment and processor for controlling walking of positive flow excavator

Abstract

The embodiment of the invention discloses a method and device for controlling walking of a positive flow excavator and a processor. The method comprises the steps that the left walking pilot pressure of a left pedal and the right walking pilot pressure of a right pedal are obtained; according to the left walking pilot pressure and the right walking pilot pressure, whether the positive flow excavator is about to walk linearly or not is judged; and under the condition that the positive flow excavator is about to walk linearly, first displacement and first opening current are determined according to the average value of the left walking pilot pressure and the right walking pilot pressure, the first displacement is determined as the displacement of the first main pump and the displacement of the second main pump, and the first opening current is determined as the opening current of the first walking valve element and the second walking valve element. Under the condition that the positive flow excavator is about to walk linearly, it is guaranteed that the displacement of the first main pump is consistent with the displacement of the second main pump, the opening current of the first walking valve element is consistent with the opening current of the second walking valve element, and the phenomenon that the positive flow excavator walks off-tracking due to the different displacement of the main pumps and the opening difference of the walking valve elements is avoided.

Description

technical field [0001] The present application relates to the technical field of construction machinery, and in particular to a method, device and processor for controlling the travel of a positive flow excavator. Background technique [0002] An excavator is an earth-moving machine that uses a bucket to excavate materials that are higher or lower than the bearing surface, and load them into a transport vehicle or unload them to a stockyard. With the development of hydraulic energy-saving technology, the hydraulic system of the excavator has developed to a negative flow rate. Control, positive flow control and other control methods. [0003] In the existing fully electronically controlled positive flow excavator travel control system, when the operator controls the travel pedal, the controller will collect the left travel pilot pressure and the right travel pilot pressure, and set the opening of the left travel spool according to the left travel pilot pressure Current, set ...
