Abstract
An advanced counting-machine is designed by DSP and linear-CCD instead of traditional PLC and photoelectric sensors.Particle feeding
detection and counting
bottle feeding and human machine interface are combined together based on the control core of DSP.Detection and counting of particles are realized by edge detection theory.The counting-machine has the characteristic of dust free
fast counting speed
and it is suitable for any size of particle.The practice proveds advantages
