Abstract

The invention provides an electric control system of an excavator, a control method and device and a storage medium, and relates to the technical field of engineering machinery. The method comprises an operating mechanism, a pilot hydraulic valve, a pilot pressure transducer component, an electro-hydraulic proportional valve component, an executing mechanism, a hydraulic main valve group and a control device, wherein the pilot pressure transducer component is arranged on a pilot hydraulic oil pipe and used for detecting pilot pressure and sending the pilot pressure to the control device in thestate that the operating mechanism acts independently, wherein hydraulic oil flows out from an outlet of the pilot hydraulic valve and generates corresponding pilot pressure; and the control device is used for calculating the control current required by the electro-hydraulic proportional valve component based on the pilot pressure. According to the electric control system, the control method anddevice and the storage medium, research and development investment can be effectively saved, and the whole vehicle production and debugging period is greatly shortened; and redundancy control requirements under various modes can be met, and the intelligent level of the excavator is improved.

Description

technical field [0001] The present disclosure relates to the technical field of engineering machinery, and in particular to an electric control system, a control method, a device and a storage medium of an excavator. Background technique [0002] With the development of the field of construction machinery, intelligent excavators with automatic functions and remote control functions play an important role in construction projects. At present, the operating handles and walking pedal devices used by mainstream excavators in the industry all adopt modular hydraulic valve design ideas. Through the operating mechanism, the pilot pressure of the output port of the hydraulic valve group is changed to control the flow rate of the output port of the main valve. Realize that the actuator completes various actions. However, the existing hydraulic valve design scheme and pilot valve control module are all mechanical structures, which cannot meet the development trend of electro-hydrauli...
