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.

Key words: pharmaceutical package, parallel data acquisition, DSP, CPLD
