Electric proportional overflow valve control method, device, system and equipment and storage medium

The invention provides an electric proportional overflow valve control method, device, system and equipment and a storage medium, and relates to the technical field of hydraulic control. The method comprises the steps that a target electric signal of the electric proportional overflow valve is determined according to the target pressure of a hydraulic pump; according to the action signal of the equipment, an electric signal is triggered to be output to the electric proportional overflow valve, and the electric signal is determined according to the product of the output value of the ramp function module and a target electric signal; in the process of gradually loading the electric signals to the electric proportional overflow valve, the real-time pressure of the hydraulic pump is detected; and under the condition that the pressure deviation between the real-time pressure and the target pressure is smaller than or equal to the allowable deviation, the electric signal currently output to the electric proportiona
