Design of HMI System for Color Group of Gravure Printing Machine Based on ARM

The work aims to design an embedded color group human-machine interface (HMI) system based on ARM to meet the functional demand of controlling gravure printing machine color group conveniently and quickly. On the basis of studying the structure of shaft-less drive control system, the functional demand of the color group HMI system was analyzed and the overall scheme of the embedded HMI system based on ARM was proposed. Altium Designer was used to design the hardware circuits of HMI system. Then, Software Keil C was applied to develop the software of HMI system, of which the performance was studied experimentally. Through experiment, the HMI system was verified to have display, touch and data management functions, and the touch accuracy was less than 5 pixels. The experimental results show that the embedded HMI system designed can meet the operational requirements of color group in gravure printing machine.
