【摘要】： 喷墨写真机是一种主要应用于广告领域的计算机外部设备。电子技术的发展和可编程逻辑器件的出现,极大地促进了喷墨写真机技术的发展,使得高速的数据传输和高精度的喷墨控制成为可能。本文分析了喷墨写真机的工作原理,比较了喷墨写真机常用的几种构架,提出了一种基于PC机+主控制板(ARM)+小车驱动板(FPGA)的新构架。该构架充分利用PC机的强大数据处理功能,减轻了下位机的负担,减少了设计成本和开发周期。文中重点介绍了热发泡式喷头的工作原理,结合该类型喷头,设计了一种基于可编程逻辑器件FPGA的喷墨写真机喷头并行驱动系统。该系统具有喷头状态检测功能,方便用户排除故障,提高工作效率。利用FPGA对USB控制器进行读写操作,实现了与PC机的高速数据传输。为了满足大容量的数据存储要求,基于FPGA设计了SDRAM控制器,控制SDRAM的数据存储。最终实现了打印介质幅宽150cm,打印速度22m2／h,打印精度1200*600DPI,基本达到了国外主流样机的性能。
[Abstract]:Inkjet photograph machine is a kind of computer peripheral equipment which is mainly used in advertisement field. The development of electronic technology and the appearance of programmable logic device have greatly promoted the development of inkjet photofinishing machine technology. Make high-speed data transmission and high-precision inkjet control possible. In this paper, the working principle of inkjet photofinishing machine is analyzed, and several frameworks of inkjet photofinishing machine are compared. This paper presents a new frame based on PC main control board (ARM) car driving board (FPGA), which makes full use of the powerful data processing function of PC and reduces the burden of lower computer. Reduced design cost and development cycle. In this paper, the working principle of hot foaming nozzle is introduced, combined with this type of nozzle. In this paper, a parallel driving system based on FPGA is designed. The system has the function of detecting the state of the jet head, which is convenient for the user to troubleshoot. In order to meet the requirement of large capacity data storage, the high speed data transmission with PC is realized by using FPGA to read and write the USB controller. A SDRAM controller based on FPGA is designed to control the data storage of SDRAM. Finally, the printing medium width is 150 cm and the printing speed is 22 m2 / h. The printing accuracy is 1200 DPI, which basically achieves the performance of the foreign mainstream prototype.
