Hydraulic excavator control system, hydraulic excavator and control method
The invention discloses a hydraulic excavator control system, a hydraulic excavator and a control method. The control system comprises an input device, a controller and a control device, wherein the input device is used for transmitting target demand current, first target current and second target current, input by a user, of an electric control pump to the controller; the controller is used for controlling to open the electric control pump and the cab ascending solenoid valve or the electric control pump and the cab descending solenoid valve according to the received cab ascending signal or cab descending signal, and controlling the electric control pump to work according to the target demand current; meanwhile, the opening degree of a cab ascending electromagnetic valve or a cab descending electromagnetic valve is controlled according to the first target current and the second target current, so that the ascending or descending speed of the cab is controlled, autonomous adjustment of the ascending or descending speed of the cab is achieved, the shaking phenomenon of the cab is avoided, and the comfort of a driver can be improved; and the mechanical service life of the hydraulic excavator is prolonged.
本发明公开了一种液压挖掘机控制系统和液压挖掘机及控制方法，控制系统包括：输入装置用于将用户输入的电控泵的目标需求电流、第一目标电流和第二目标电流传输给控制器；控制器用于根据接收的驾驶室上升信号或驾驶室下降信号控制打开电控泵和驾驶室上升电磁阀或电控泵和驾驶室下降电磁阀，并根据目标需求电流控制电控泵工作，同时根据第一目标电流和第二目标电流控制驾驶室上升电磁阀或驾驶室下降电磁阀的开度，以控制驾驶室的上升或下降速度，实现了对驾驶室升降速度的自主调节，避免了驾驶室出现抖动现象，能够提高驾驶员的舒适感，进而提高液压挖掘机的机械使用寿命。
