SYSTEM FOR CONTROLLING CONSTRUCTION MACHINE AND METHOD FOR CONTROLLING CONSTRUCTION MACHINE USING SAME

摘要

A system for controlling a construction machine comprises: a pressure reduction valve receiving control oil from a pilot pump to generate pilot signal pressure to control movement of a hydraulic spool inside a main control valve; an angle sensor to detect a rotation angle of a work device operated in accordance with movement of the hydraulic spool; and a control unit receiving angle information of the work device from the angle sensor, outputting a control signal to the pressure reduction valve when the angle is placed within a predetermined angle range having a stroke end position of the work device to reduce intensity of the pilot signal pressure.;COPYRIGHT KIPO 2017
