Abstract

The invention discloses an automatic control system and control method of a working device of an excavator, wherein the system comprises a movable arm, a dipper handle, a dipper angle sensor, a movable arm cylinder, a dipper handle cylinder, a dipper cylinder pressure sensor, a speed sensor, a movable arm cylinder, a dipper handle cylinder, and dipper cylinder electro-hydraulic proportional valves. The system is characterized in that (1) a laser position indicator is equipped for detecting the relative positions of the working device of the excavator and an excavated object; (2) a programmable controller receives signals from the sensors, and controls the electro-hydraulic proportional valves; and (3) a BP (back propagation) neural network module is adopted for controlling. According to the invention, the position and posture of a dipper can be accurately controlled, and the automatic control on the working device of a hydraulic excavator can be realized.

Description

technical field [0001] The invention relates to a method and device for controlling an excavator, in particular to a method and a device for automatically controlling the working device of the excavator. Background technique [0002] Hydraulic excavator is a kind of widely used engineering machinery. Its working environment is harsh, and because of the single operation action, long-term operation can easily cause driver fatigue. The application of microcomputer to control the hydraulic excavator will inevitably reduce the labor intensity of the driver, improve labor efficiency, save energy and improve safety. [0003] Due to the large changes in the operating objects and environments of excavators, excavation operations must adapt to various working conditions and soil environments, and the content and requirements of each specific operation are different during construction, so it is difficult to form a rule, which requires the selection of control methods It should have t...
