In order to meet the need of medicine packaging industry for high speed and precision

the electronic granulation counter is developed.The counter consists of LED light source

double linear array CCD chip TCD1209D

synchronously driving circuit for the double linear array CCD chip based on CPLD EPM 3064A

synchronously data acquisition card of the high speed A/D converter TLC 5510

and host computer.The test channel is 400 mm wide;the horizontal resolution on the medicine pill is 0.1 mm

the driving frequency of linear array CCD is 10 MHz and the vertical resolution on the medicine pill is 0.3 mm

software binarization method is used for identification on the medicine tablets with different light transmittance.The experimental results show that the count of electronic granulation counter is accurate and reliable

counting speed is 8 000 particles/min

and can correctly distinguish the broken tablets and the overlap tablets.
