Abstract
The disclosure relates generally to the field of boom-type engineering machinery, which discloses particularly an engine speed control method used to control an output speed of an engine of a boom-type engineering machine during a boom action including: detecting a load pressure of a hydraulic system and a moving speed of a boom; determining a target speed of the engine according to the load pressure and the moving speed of the boom, by a central control unit; and sending, by the central control unit, the target speed of the engine to an engine control unit, and performing, by the engine control unit, a speed closed-loop adjustment according to a current speed value fed back by the engine, so that a current speed of the engine is consistent with the target speed of the engine. Further aspects are an engine speed control system and a boom-type engineering machine equipped therewith.
