The invention provides an intelligent safety energy-saving hydraulic control system for a dumper. The hydraulic control system comprises an electric control unit, a pressure sensor and a signal output unit, the signal output end of the pressure sensor is connected with the signal input end of the electric control unit, the signal output end of the electric control unit is connected with the signal input end of the signal output unit, and the pressure sensor is arranged on an oil way of a dumper hydraulic control unit. The system further comprises a speed adjusting device connected with a hydraulic pump of the dumper hydraulic control unit. The flow demand of the hydraulic system is automatically recognized through pressure detection, a mechanical friction speed adjusting mechanism is used for adjusting the rotating speed of a gear pump so as to adjust the output flow, and under the condition of meeting the flow demand, oil source heat emission and energy loss caused by overflowing are reduced. Working condition parameters of the dumper working process are detected and recorded in the whole course, the hydraulic system is monitored, faults possibly occurring are judged, and accidents are prevented and controlled.
