摘　　要：设计了一套适用于颗粒工件计数的自动计数仪控制系统。该系统使用红外光电传感器作为检测元件,当有工件通过时红外光被遮挡,传感器接收端产生相应的脉冲信号,通过对脉冲信号进行计数,实现对工件的自动计数。对控制系统的硬件电路和软件控制流程作了详细介绍并进行了样机验证,结果表明,该系统能对不同直径的颗粒工件进行快速、准确地计数。With infrared transmitting and receiving module as sensor,when a workpiece passes through the surveyed area,the light will be blocked by the workpiece and the receiving module will emit a pulse signal,the counting for the passing workpiece just is the workpiece number.An on-line type automatic control photoelectric counter system is developed based on this photoelectric detection method.The experiments show that the instrument has the advantages of precision counting,fast detection speed and strong practicability.
