\Currently, the study of the folding machine at home and abroad are mainly concentrated in the gluing control, automatic cementing and folding machine, hot melt folding machine. To a certain extent, the folding machine intelligent control on plastic, but the existing the folding motion control of the folding machine still driven by the mechanical movement of bodies and manual common CNC folding machine development and research in foreign countries has not been reported. In this paper, and to achieve a CNC folding machine control system based on FPGA (Field Programmable Gate Array), the language hierarchical system using VHDL (Very High Speed ??Integrated Circuit Hardware Description), hardware and software co-design and modular program design methods, to shorten the development cycle, and enhance the reliability of the system, ease of system upgrades. With the development of the microprocessor, embedded technology in complex industrial control applications are increasingly becoming industrial control the direction of technology development, FPGA-MCU-based control system technology. Folding machine control system is a typical electromechanical control systems, it is a multi-parameter systems of different nature, a combination of different control objects, both multi-axis motion and position control, but also the flow and temperature of process control, a more complex mechanical and electrical control systems. Microcontroller as the core microcomputer control system, due to the order of the program control complex control object, so that the CPU workload is too heavy, the impact of the system real-time and stability. This paper presents an ARM-FPGA based embedded software and hardware solutions for industrial control systems, ARM processor is responsible for the man-machine interface, communication and FPGA, FPGA is responsible for multiple I / O output temperature detection and limit position detection I / O output include: multi-axis control, memory read and write control, flow control, keyboard scanning and temperature signal acquisition. Plays an important role in the control system, FPGA, embedded soft core processor (Nios Ⅱ) for completion of ARM communications, data processing, as well as task scheduling of various functional modules, and by virtue of its strong processing capability, flexible configuration The way to make the system more simple, flexible design. CNC folding machine control system of the subject control core FPGA board-level design, parallel processing capability, portability, features not only simplifies peripheral integrated circuits and data acquisition interface, enhanced control system within data interaction capabilities, to improve the level of automation of the folding machine, and also promote the digital development of the folding machine.
