Abstract

The invention discloses an intelligent control system and method for a hydraulic excavator. The intelligent control system for the hydraulic excavator comprises a proportional variable pump, an activecompensation load-sensitive module, a master controller, a control handle, a pedal valve, an oil cylinder, a motor, and other hydraulic elements. The load condition of the oil cylinder or (and) the motor is detected through the master controller, the load condition of the oil cylinder or (and) the motor and data information input by the active compensation load-sensitive module are analyzed and operated, a processing result is converted into a control signal, the control signal is output to the variable pump and the active compensation load-sensitive module, and thus, the intelligent controlsystem is controlled. By adoption of the intelligent control system and method for the hydraulic excavator, the problems that a feedback oil circuit of an existing load-sensitive system for the hydraulic excavator fluctuates, the response speed is affected by the length of a pipeline, and consequentially, system matching is difficult, and a response cannot be not given in time are solved, the system drive efficiency is improved, the flow loss is reduced, system heat is reduced, and the energy-saving effect is realized.

Description

technical field [0001] The invention relates to the field of hydraulic excavators, in particular to an intelligent control system and control method applied to hydraulic excavators. Background technique [0002] Excavators include walking, slewing, stick, boom, bucket and other execution actions. The execution of each action is realized through a high-pressure, large-flow hydraulic system. At present, excavators adopt a load-sensitive hydraulic system, which can realize the compound action of multiple actuators under different load pressures to meet the construction needs of excavators. However, since the system relies on hydraulic oil to transmit pressure feedback signals through its own pipeline and damping, it can control the flow distribution of the system. This control method has shortcomings such as feedback oil circuit fluctuations, response speed affected by the length of the pipeline, system matching difficulties, untimely response, etc., resulting in low transmiss...
