| description | The invention relates to a full-electric-control hydraulic control system. The problem that part of faults of an existing full-electric-control hydraulic control system cannot be diagnosed and recognized is solved. The full-electric-control hydraulic control system comprises an electric control main valve, an electric handle, a controller and an angle sensor for detecting the swing angle of the electric handle. When the handle voltage output by the electric handle is out of the handle voltage preset range determined by the handle swing angle according to the angle and voltage corresponding relation, the controller does not output the control current to a proportional electromagnetic valve. According to the full-electric-control hydraulic control system, the operation state of the whole machine is comprehensively judged, the judgment is more accurate and perfect, and the potential safety hazard problem when the full-electric-control system is abnormal is effectively solved.
