Abstract

The invention provides an executing mechanism track control method, device, and system of engineering machinery, a controller and a storage medium, and relates to the technical field of engineering machinery. The method comprises the steps that whether the engineering machinery enters a track control mode or not is determined on the basis of an instruction, and an executing mechanism of the engineering machinery is adjusted to an initial position of a preset track; an initial current value of a pilot electromagnetic valve is determined according to real-time angle information and preset expected angle information; the initial current value of the pilot electromagnetic valve is corrected based on hydraulic oil temperature information and pressure information, and a working current value ofthe pilot electromagnetic valve is determined; and a current is output to the pilot electromagnetic valve based on the working current value. According to the method, device and system, the controllerand the storage medium, the current of the pilot electromagnetic valve can be corrected in real time according to an operation environment temperature and operation working condition pressure, and track control adaptability and track control precision are improved.

Description

technical field [0001] The present disclosure relates to the technical field of construction machinery, and in particular to a method, device, controller, system and storage medium for controlling the track of an actuator of construction machinery. Background technique [0002] With the development of the field of construction machinery, intelligent construction machinery with automatic functions and remote control functions plays an important role in construction projects. There are many types of construction machinery, such as excavators. With the advancement of science and technology, the intelligent development of excavators has also entered a period of acceleration. In some special operations such as rescue, slope repair, and ground leveling, excavators are required to carry out unmanned operations. The key technology of unmanned driving is the trajectory control technology of the blade tip. The trajectory control method commonly used in the industry is to compare the a...
