A method of photovoltaic cable extrusion control

By combining a quaternary coupling model and machine learning algorithms, the screw speed and die temperature are adjusted in real time, solving the problems of thermal hysteresis and equipment response delay in the photovoltaic cable forming process. This enables precise control of the outer diameter of the insulation layer and sheath layer, improving the production stability and insulation performance of the cable.

Abstract

The present application belongs to the technical field of photovoltaic cable, and particularly relates to a photovoltaic cable extrusion control method.S1: high-frequency data acquisition: introduce temperature-pressure-velocity model data to obtain dynamic extrusion temperature, melt pressure and extrusion speed parameters in the extrusion process; introduce infrared online diameter measuring instrument to collect real-time data of cable insulation layer outer diameter and sheath layer outer diameter; establish an influence intermediate value, which includes thermal conduction lag time, melt flow lag time and equipment response lag time; establish a four-element coupling model of traction speed-melt pressure-temperature-predicted outer diameter; S2: change trend prediction; S3: parameter adjustment; S6: dynamic cooperative control, through the four-element coupling model established based on the speed-temperature-pressure collection model combined with the real-time data of the insulation layer outer diameter and the sheath layer outer diameter, the problem of passive logic easy to repeatedly vicious cycle adjustment of 'waiting for deviation exceeding the standard and then adjusting' is solved.
