Abstract: front page image
(EN) The present invention relates to a control system of construction equipment and, more specifically, to a control system of construction equipment in which an electronic HRV controlled by an ECU is connected to a hydraulic circuit for operating a cylinder, thereby exhibiting more excellent efficiency than when a hydraulic HRV is applied. To this end, the present invention provides a control system of construction equipment, the system comprising: a spool switched by a pilot signal pressure applied by operating a joystick to enable a hydraulic oil to move from a hydraulic pump to a cylinder and from the cylinder to a hydraulic tank; an HRV installed on a travel path of the hydraulic oil moving between the spool and the cylinder, the HRV being opened/closed to control the movement of the hydraulic oil; and an ECU electrically connected with the HRV to control the opening/closing of the HRV.
(FR) La présente invention concerne un système de commande d'équipement de construction et, plus spécifiquement, un système de commande d'équipement de construction dans lequel un HRV électronique commandé par une Unité de Commande Électronique est connecté à un circuit hydraulique permettant le fonctionnement d'un cylindre, ce qui présente ainsi d'excellentes caractéristiques d'efficacité comparé au cas où un HRV hydraulique est appliqué. À cet effet, la présente invention concerne un système de commande d'équipement de construction comprenant les éléments suivants: une bobine commutée par une pression de signal pilote appliquée par l'actionnement d'une manette qui permet à une huile hydraulique de se déplacer d'une pompe hydraulique à un cylindre et depuis le cylindre à un réservoir hydraulique; un HRV installé sur le trajet d'écoulement de l'huile hydraulique qui se déplace entre la bobine et le cylindre, et étant ouvert/fermé afin de contrôler l'écoulement de l'huile hydraulique; et une Unité de Commande Électronique connectée électriquement avec le HRV afin de contrôler l'ouverture/la fermeture de celui-ci.
(KO) 본 발명은 건설장비의 제어 시스템에 관한 것으로서 더욱 상세하게는 실린더를 동작시키는 유압 회로에 ECU에 의해 제어되는 전자식 HRV를 연결함으로써, 유압식 HRV를 적용한 경우보다 우수한 효율성을 나타내는 건설장비의 제어 시스템에 관한 것이다. 이를 위해, 본 발명은, 조이스틱 조작을 통해 인가되는 파일럿 신호압에 의해 절환되어, 유압펌프로부터 실린더 및 상기 실린더로부터 유압탱크로 작동유의 이동을 가능하게 하는 스풀; 상기 스풀과 상기 실린더 사이를 이동하는 작동유의 이동 경로 상에 설치되어, 개폐를 통해 상기 작동유의 이동을 제어하는 HRV; 및 상기 HRV와 전기적으로 연결되어, 상기 HRV의 개폐를 제어하는 ECU를 포함하는 건설장비의 제어 시스템을 제공한다.
