According to the intelligent control system and the control method thereof, the problem of automatic driving of the hydraulic excavator is solved, intelligent driving and unmanned operation of the excavator are achieved, the intelligent degree is high, and the system and the method are suitable for various working conditions.

Description

technical field [0001] The invention relates to an excavator intelligent control system and control method based on a limited sensor, and belongs to the technical field of hydraulic excavators. Background technique [0002] In construction machinery, hydraulic transmission is widely used due to its advantages of large energy capacity, stable transmission, and strong speed regulation ability. Among them, hydraulic excavators are widely used in the field of infrastructure construction. [0003] Existing hydraulic excavators rely largely on manual driving and operation, and the degree of automation is not high, so they cannot be better applied to various working conditions. Contents of the invention [0004] Aiming at the problems existing in the above-mentioned prior art, the present invention provides an excavator intelligent control system and control method based on limited sensors. It is better applicable to various working conditions. [0005] In order to achieve the...
