【摘要】 电脑绣花机是随着电子技术和机电一体化技术发展逐渐发展起来的电脑刺绣设备,它极大地提高了纺织行业的生产力,随着刺绣品需求量的增加,高性能的电脑绣花机越来越受到人们的青睐。我国电脑绣花机控制系统发展相对而言比较落后,而我国又是纺织大国,因此高性能电脑绣花机控制系统的研究也提上了日程。 本论文在对电脑绣花机系统的结构和功能进行分析的基础上,提出了一个以ARM微处理器和CPLD器件为中心构建硬件平台的绣花机控制系统解决方案。 本系统以Samsung公司的ARM芯片S3C4480作为核心控制器,外围扩展了USB HOST、LCD显示器、RTC、UART接口、2Mbyte的FLASH等功能模块。以Altera公司的CPLD芯片EPM570T144C5作为协控制器,解决了I/O口、4*8键盘的扩展,并系统的管理了外部中断。 本系统中还以SL811HST芯片作为USB接口芯片,结合微软公司的FAT16文件系统,自主开发出了一套优盘文件读写系统,使得优盘在微控制系统中的应用得到了进一步的发展。该电脑绣花控制系统性能优良,运行稳定,抗干扰能力强,不失为一套具有先进型、新颖性、实用性的控制系统。更多还原

【Abstract】 The computerized embroidery machine is a device with the development of electronics and mechanical automation, it increases the productivity of textile industry. The computerized embroidery with high performance is becoming more and more popular with the increase of requirement of embroidery. In our Country the thechnology of the embroider machin’s control system has dropped behind the developed country, but our country has the strong require of textile, so the research of the computer embrtoider machine must be payed more and more attentions.Based on the analysis of construction and function of the system, the project proposes a design of an embedded control system based on ARM and CPLD for the embroidery machine.In the control system, we use S3C44B0 to be the core controller and develop some function modules: USB HOST controller, LCD, real time clock, UART port and 2 Mbyte FLASH. Coprocessor EPM570T144C5 of Altera Company increases the number of I/O port and manages the external interrupt.hi this control system, we use SL811HST chip to be the USB interface chip, develop a flash disk file access system based on the FAT 16 file systerm of Microsoft. The flash disk’s application has become more extensive. This control system’s application has proved the embroider machine contorl system have good perfomance and stablity, is novel practicable control system.更多还原
