摘要
本文介绍XH-18单头电脑绣花机控制系统的工作原理。该机以8031单片机为CPU,采用串行口及移位寄存器为显示的键盘接口,以8155扩展I/O为外接花版输入地址,并用步进电机恒流斩波驱动方式,经使用证明电路设计合理,整个控制系统稳定可靠,适用于较简单的单头绣花机型。
Introduces detailly the designing scheme and circuit of the control system of XH-18 coputerized embroidery machine. And also points out emphatically the principle of the constant current chopped wave driving method of the stepping motor.
