基于线阵CCD的纱线计数器设计

Design of Yarn Counter Based on the Linear CCD

基于线阵电荷耦合元件(CCD)的纱线计数器,采用TCD1501D为图像传感元件,利用复杂可编程逻辑器件产生稳定的时序脉冲驱动CCD元件,传感器输出图像信号经滤波放大和AD转换后由ARM微控制器采集。采集的数据在ARM内部进行二值化处理,实现纱线计数。详细介绍了系统软硬件设计。实验测试证明了系统设计的正确性。

Based on the yarn counter with the linear CCD,this paper uses TCD1501D as an element,and the CPLD to produce stable temporal pulse to drive CCD.The image signal of CCD collected by ARM after filter,amplification and AD conversion.The data in the ARM for binarization realize the yarn count.The system software and hardware are introduced in detail.The whole system is simple and stable.
