【摘要】 为解决基于单片机的电子提花机所面临的问题,提出一种新的基于单片机W78E516B的嵌入式提花机控制器,包括硬件电路和单片机软件。分析了控制器实际中遇到的及可能遇到的技术问题,提出相应的对策。用U盘代替软盘输入花样数据,解决了花样纬数受限制的实际问题。控制器实现了意外停机保护功能,且意外停机后可以快速恢复生产,文件管理系统经过反复拷贝删除也不会产生碎片。经在多家工厂运行,结果表明使用该控制器的提花机动作简洁、准确。更多还原

【Abstract】 In order to solve the problems confronted in designing the jacquard MCU based controller,a new method is presented to develop jacquard MCU W78E516B based controller,including hardware and software.Both the encountered and potential technical problems in the realization of the conlroller are analyzed,and corresponding measures are proposed.By replacing the traditional floppy drive with USB interface, the problem of weft number restricting the pattern is solved.Furthermore,our approach can protect the data at unexpected shutdown,so that after an accident it can make rapid resumption of production,and produces no scrap file in spite of frequent deletion and copy,which is ensured by the files manager system.This controller has been put into operation in several mills,and the results show that it works smoothly and accurately.更多还原
