The invention provides an engineering machinery control method, device and system and engineering machine.The method comprises the steps that when the engineering machinery is in an automatic working mode, the first walking speed of the engineering machinery is calculated according to the pulsation change of the main pump pressure of the engineering machinery, calculating a second walking speed of the engineering machinery according to the main pump current of the engineering machinery; and calculating a target walking speed of the engineering machinery according to the first walking speed and the second walking speed, and controlling the engineering machinery to walk based on the target walking speed. The walking speed of the engineering machine can be obtained by combining the pressure pulsation signal and the main pump current for calculation, the engineering machine is controlled by controlling the main valve element electromagnetic valve and the energy supply component, and the control sensitivity and the adjusting precision can be improved.
