(KO) 건설기계의 제어 시스템 및 건설기계의 제어 방법
Abstract:
(EN) A system for controlling a construction machine comprises: a hydraulic pump; at least one control valve provided at a center bypass line connected to the hydraulic pump, and controlling the flow direction of hydraulic oil discharged from the hydraulic pump so as to selectively supply the oil to an actuator; a bypass control valve, provided at the lower side of the control valve on the center bypass line, for variably controlling the flow rate of the hydraulic oil discharged to a drain tank through the center bypass line; and a control unit for controlling the operations of the hydraulic pump and the bypass control valve according to an operation signal of an operator, and opening the bypass control valve when the pump peak is generated so as to reduce a pump peak.
(FR) Cette invention concerne un système de commande d'un engin de chantier, comprenant : une pompe hydraulique ; au moins une vanne de commande disposée sur une ligne de dérivation centrale raccordée à la pompe hydraulique, et commandant le sens d'écoulement de l'huile hydraulique évacuée par la pompe hydraulique de façon à fournir sélectivement l'huile à un actionneur ; une vanne de commande de dérivation, disposée sur le côté inférieur de la vanne de commande sur la ligne de dérivation centrale, pour commander de manière variable le débit de l'huile hydraulique évacuée vers un réservoir de vidange par l'intermédiaire de la ligne de dérivation centrale ; et une unité de commande pour commander les opérations de la pompe hydraulique et de la vanne de commande de dérivation en fonction d'un signal d'actionnement d'un opérateur, et ouvrir la vanne de commande de dérivation lorsque le pic de pompe est généré de façon à réduire un pic de pompe.
(KO) 건설기계의 제어 시스템은 유압 펌프, 상기 유압 펌프에 연결된 센터바이패스 라인에 설치되고 상기 유압 펌프로부터 토출된 작동유의 흐름 방향을 제어하여 액추에이터에 선택적으로 공급하기 적어도 하나의 제어 밸브, 상기 센터바이패스 라인 상에서 상기 제어 밸브 하류에 설치되며 상기 센터바이패스 라인을 통해 드레인 탱크로 배출되는 상기 작동유의 유량을 가변적으로 제어하기 위한 바이패스 제어 밸브, 및 작업자의 조작 신호에 따라 상기 유압 펌프 및 상기 바이패스 제어 밸브의 동작을 제어하고 펌프 피크 발생 시 상기 바이패스 제어 밸브를 개방시켜 펌프 피크를 감소시키는 제어부를 포함한다.
