基于SOPC技术横机控制系统人机界面研制

针对电脑横机人机界面系统集成度低、抗干扰能力差等问题,提出了一种基于SOPC技术的电脑横机控制系统的人机界面研制方法。在EP4CE115 FPGA芯片上配置了NiosIICPU软核、SDRAM控制器、LCD控制器、JTAG调试模块,通过SPI接口扩展触摸屏控制器,构成了人机交互界面。软件设计部分用VerilogHDL语言编写,主要包括LCD驱动程序、触摸屏中断程序等。研究结果表明,该种电脑横机人机界面具有系统集成度高、抗干扰能力强、功耗低、灵活性强的特点。

Development of knitting machine control system human-machine interface based on SOPC technology

Abstract： In order to solve the problems of low system integration and the week anti-jamming capability in the human-machine interface of knitting machine,a method of developing computerized knitting machine control system human-machine interface based on SOPC technology was proposed. By extending touch screen controller through the SPI interface,the human-machine interface was established by configuring a Nios II CPU soft-core,SDRAM controller,LCD controller,JTAG debug module in the EP4CEI15 FPGA chip. The software designing used Verilog HDL language to write,including LCD driver,touch-screen interrupt etc.. Study results show that the kind of human-machine interface has merits of high system integration, strong anti-jamming capability, low power consumption, and is more flexible.
