Abstract
The present invention relates to a system for controlling a construction machine and a method for controlling the same, and the system comprising: a bucket control valve which controls the supply of hydraulic oil to a bucket cylinder provided to operate a bucket; a vehicle control unit which controls the bucket control valve by applying a current value to the bucket control valve; a pilot cutoff switch which controls the cutoff of pilot oil pressure controlling the driving or operation of a vehicle and transmits the cutoff to the vehicle control unit; and a bucket joystick which receives a signal from an operator and transmits the signal to the vehicle control unit.
Claims15
A control system for a construction machine, comprising:
- a bucket control valve for controlling supply of hydraulic oil to a bucket cylinder provided to operate a bucket;
- a vehicle control unit that applies a current value to the bucket control valve to control the bucket control valve;
- a bucket joystick that transmits a bucket control signal to the vehicle control unit and includes a switch for actuating the bucket or a device other than the bucket;
- an arm position detection unit that detects a position of an arm connecting the bucket and a vehicle and transmits the position of the arm to the vehicle control unit;
- and
- a bucket position detection unit that detects a position of the bucket and transmits the position of the bucket to the vehicle control unit,
- wherein the vehicle control unit performs bucket dusting when receiving a specific signal from the switch in a state in which the position of the arm is at or above a first set position, the position of the bucket is at or below a second set position, and the bucket joystick is in a neutral state.
A control method of a control system for a construction machine, comprising:
- receiving status information of a pilot cut-off switch;
- and
- receiving a specific signal from a bucket joystick,
- wherein a vehicle is switched to a standby state in which bucket dusting is practicable when the pilot cut-off switch is in an off state and the specific signal transmitted by the bucket joystick is input.
