基于Qt的电脑横机上位机系统

摘要

电脑横机是自动化程度较高的机电一体化纺织机械,随着电脑控制的针织机械的普及,人们对高性能的电脑横机的需求越来越大.电脑横机控制系统分为上位机与下位机,为了实现电脑横机上位机与下位机的信号快速处理以及获得更加人性化的人机交互,引入一种基于Qt的电脑横机上位机系统.采用处理器ARM9 S3C2416及扩展电路作为横机上位机系统的硬件载体,将嵌入式Linux作为控制器软件操作平台,通过GPIO口模拟总线的方式,实现上位机与下位机的通信.通过分析横机需求以及系统的实现方式,从嵌入式系统的实际性能出发,采用Qt开发人机交互界面,实现数据处理和显示,最终实现编织功能.与传统的横机上位机系统相比,功能更强,实时性更好,软件界面更加人性化.%Computer flat knitting machine is a high degree of automation of mechanical and electrical integration of textile machinery.With the popularity of computer control of knitting machinery,the high performance of computer flat knitting machine is needed more and more.Computer flat knitting machine control system is divided into host computer and slave computer.In order to achieve the rapid signal processing of computer flat knitting machine between upper machine and lower machine as well as more humanized human-computer interaction,a computerized flat knitting machine computer system based on Qt is introduced.It uses processor of ARM9 S3C2416 and extension circuit as the hardware carrier of flat knitting upper machine system,taking the embedded Linux as the controller software platform to realize the communication of upper machine and lower machine through simulating the bus by the GPIO port.By means of analyzing the demand of flat knitting machine and the way of the realization of the system,Qt development of human-computer interaction interface is used by stating from the actual performance of the embedded system,which has realized data processing and display,as well as the function of weaving finally.Compared with the traditional flat knitting machine system,the function of this system is stronger with better real-time performance and more humanized software interface.
