Design and Research of Control System of the Large-Scale Accumulator Blow Molding Machine Based on PLC

Abstract

On the basis of process flow of the large-scale blow molding machine, make PLC as the control center, touch screen as the human-computer interface, this passage introduce the overall plan of the control system, hardware configuration and design procedures of the software, make communication technology come true between PLC and HMI with MPI, Use PID technology, make the wall thickness come true by the way of cubic spline interpolation.
