The invention discloses an intelligent
excavator control system and method based on a limited sensor. Comprising a visual sensor, a first displacement sensor, a second displacement sensor, a third displacement sensor, a
safety valve, a hydraulic
oil tank, a proportional variable pump, an engine, a one-way valve, a first three-position four-way hydraulic valve, a second three-position four-way hydraulic valve, a third three-position four-way hydraulic valve, a fourth three-position four-way hydraulic valve, a fifth three-position four-way hydraulic valve, a sixth three-position four-way hydraulic valve and a rotary
hydraulic motor. The device comprises a bucket rod oil cylinder, a movable arm oil cylinder, a bucket oil cylinder, a left walking
hydraulic motor, a right walking
hydraulic motor and a whole
machine controller. The visual sensor, the displacement sensors, the
safety valve, the hydraulic
oil tank, the proportional variable pump, the engine, the one-way valve and the three-position four-way hydraulic valves are all connected with the whole
machine controller. 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.
