Control method, and control device for auxiliary pipeline of excavator, working machine and electronic apparatus

A control method for an auxiliary pipeline of an excavator, comprising:

• acquiring a pressure difference between an input end and an output end of the auxiliary pipeline of the excavator;
• obtaining an output flow of the auxiliary pipeline based on the pressure difference;
• and
• controlling the output flow of the auxiliary pipeline to adjust to be within a target flow range in response to that the output flow of the auxiliary pipeline is beyond the target flow range,
• wherein obtaining the output flow of the auxiliary pipeline based on the pressure difference comprises:
• inputting the pressure difference to a relationship model between the pressure difference and the output flow of the auxiliary pipeline to obtain the output flow of the auxiliary pipeline;
• wherein the relationship model between the pressure difference and the output flow is obtained by the following method:
• acquiring multiple sets of experimental data of the pressure difference and multiple sets of experimental data of the output flow of the auxiliary pipeline;
• and
• fitting the multiple sets of experimental data of the pressure difference and the multiple sets of experimental data of the output flow based on an interpolation method to obtain the relationship model between the pressure difference and the output flow.
