| 摘 要： | 为提高数粒机的的计数速度和精度,设计了一种计数系统。该系统以光电传感器作为检测机构,使用CPLD、DSP双核控制系统,采用多通道相互独立、并行采集的工作方式。系统可实现颗粒药品包装前的计数,并在一定程度上进行残缺药品的检测与识别。理论上每通道计数速度可达3 000粒/min以上,实际计数速度为1 000粒/min左右。对药品直径在3~20 mm的不规则物体均可实现准确计数。

| Abstract: | We devise a counting system to improve the counting speed and accuracy.It employs a photoelectric sensor to serve as a detection element,the double-core control system of DSP and CPLD,and work mode of multi-channel independence and parallel data acquisition.It can realize counting prior to particle drug packaging and identify incomplete drug to some extent.The counting speed of every channel can theoretically reach 3 000 grain/min.However,the actual speed is about 1 000 grain/min.it can accurately count the drugs with diameter of 3 ～ 20 mm. |
