摘要
本文针对在线检测中出现的纱线不匀问题,通过RS-232C串口通讯,设计了上位机与欧姆龙PLC-CJ1M(CPU21)之间的数据通信,采用基于Windows操作系统功能强大的面向对象的程序设计语言——Visual Basic,编写了上位机程序,而无需在PLC中编写任何程序,可以在线获得纱线的检测数据,及时反映纱线的不匀。
Based on the problem of the yarn unevenness of the online detecting, the paper designed data communication between personal computer and OMRON PLC-CJ1M（CPU21） by RS-232C serial port communication. The program which realize communication were compiled on using powerful and object oriented programming to designing language--Visual Basic in Windows operation system. The data can be gotten by online yarn detecting, and can reflect yarn unevenness.
