光电传感自动计数仪控制系统的设计

Photoelectric Sensor Design of Automatic Counting

针对工件计数,设计了一套用于工件计数的自动计数仪控制系统,该系统采用光电检测的方法,利用红外发射、接收模块作为传感器,当有工件通过时红外光被遮挡,接收模块将产生一个脉冲信号,对此脉冲信号进行计数,就可以实现对工件计数.实验证明,该系统能对不同直径的工件进行快速、准确的计数.

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.
