基于单片机的织机通用计长装置研究

Study on a General Electronic Length Counter Designed for Loom

文章介绍了一种基于单片机的织机通用计长装置的构成、原理及应用。该装置采用8位单片机作为主控单元,利用按键和液晶显示屏进行信息交互,通过对霍尔传感器传来的打纬信号进行计数,结合输入的纬密进行计长,纬密输入范围为1~65535;同时使用了时钟芯片,能同步显示时间并自动计算时间效率。装置通用性强,灵活性好,适用各种织机,并能对重纬、双层和多层等织物进行准确计长。

The structure,theory and application of general electronic length counter was introduced.The length was measured by counting the number of weft,and the result with weft density was given.Scope of weft density can be 1~65535.Hardware is composed of 8-bit microcontroller as main control unit,the hall sensor to get the beating-up signal,and the key and LCD to exchange information,and RTC chip provides time signal,on this base the time efficiency can be countered.The counter is cost-effective,simple to use,suitable to kinds of loom and can measures the length of weft rib,double and multi-layer fabrics exactly.
