Design Of Embroidery Machine Control System Based On ARM

Today the market of embroidery machine is developing quickly, as the most essential part of embroidery machine, the control system is the key of performance improvement and cost reduction. In this dissertation, a embroidery machine control system based on ARM processor, which possesses advanced technology, compact function and high cost performance, is designed unifying the collaborative project "embroidery machine control system" of Huwang Science and Technology Corporation and Zhejiang University. According to the development process of embedded system, the functional module of the control system is divided, the overall framework is constructed, the hardware and software platform are chosen, and the hardware and software is designed using advanced method.In Chapter 1, the developing process and status of embroidery machine and it's control system are introduced. The definiens, characteristic and development of embedded system are dissertated. The development history, studying and applying status of ARM processor is expatiated. The main contents of this dissertation are rised. Finally, the structure of this dissertation is given.In Chapter 2, the developing process of embedded system is expatiated. The coordinated design method is chosen as the design method of this control system. The technical function and design procedure of Electronic Design Automation technology are dissertated, the principles of Structured Design Method and Object-Oriented Design Method are discussed in particular. Finally, the design criterion of the embroidery machine control system is given.In Chapter 3, according to the consumer demand, the functional module of the embroidery machine control system is divided, the overall framework of the system is constructed, and the function of each module is analyzed in particular. The CPU chips of master system and slave system, the real-time operating system and the development environment, which are applicable to the embroidery machine control system, are chosen in terms of the lectotype principles.In Chapter 4, on the basis of the selected CPU chips, the hardware frame of the embroidery machine control system is determined according to the overall framework. The power circuit, reset circuit, memory interface circuit, keyboard and display circuit, USB interface circuit, serial communication interface circuit and nether electromechanical interface circuit are designed in particular.In Chapter 5, the software frame of the embroidery machine control system is constructed in the light of the hierarchy of master system and slave system. The programs of keyboard entry, graphical display, USB drive, pattern store and management, serial communication and electromechanical control are designed. In Chapter 6, the review and conclusions of this thesis are summarized and the future research work is sketched out.
