Research Of Speed Improvement For Data Communications Of Digital Textile Printer

In recent years, with the rapid development of China's textile industry, large format digital printer of textiles showing unprecedented prosperity, the market demand for its textile industry continue to promote the commercial interests of the industrialized development of digital printing equipment. After 2001, domestic large-format digital inkjet printing equipment in the market emerge, and its astonishing speed inkjet printers for the domestic technology continues to upgrade and transformation. To occupy textile digital inkjet printing equipment market to be in the print speed and accuracy have a significant advantage.Textile digital printing technology is the use of digital piezoelectric substrate in a special textile screen printing large format color printing and dyeing equipment. Data communications system is part of the core digital presses, to complete the PC real-time image data processing, data buffering, data transmission, coordination of print head control. Data communication system will directly affect speed digital inkjet printing machines and printing accuracy. This digital printing of textiles designed transmission system is the use of S3C2440 32-bit embedded ARM processor as master and use FX2LP CY7C68013A chip constitutes a standard peripheral communication interface USB2.0, high speed data transmission. Digital presses with the textile printing speed, high resolution, and reliable system operation.In this paper, textile digital printing machine communication interface part of a careful study and concluded, in the USB2.0 protocol after a thorough analysis for bulk transfer to a large number of optimization experiments, raise more endpoints portfolio optimization model. The firmware on the FX2LP CY7C68013A a comprehensive optimization, through the use of Slave FIFO transfer mode to further enhance the data transmission speed digital presses, and USB2.0 interface devices for the hardware components and processes described. Finally, focus on the framework of a new generation of WDF driver communication system in the textile digital printing press in the development process, so that the textile digital printing presses and precision printing speed has been greatly risen.
