为实现对磁性零件的在线计数检测，开发了一种在线式磁性零件激光光电计数仪系统。
To accomplish on-line count inspection for magnetic parts, a kind of laser photoelectric counter system is developed based on photoelectric inspection theory.
设计了光电编码器用可编程计数电路。
A programmable count circuit for photoelectric encoder is designed.
加之每块计数模板控制通道数量的限制，在光电编码器应用数量较多的系统中，会增加计数模板的数量并占用大量的系统资源，增加控制成本。
The number of each counter modules channel is limited, it needs a lot of counter modules and system resource in the system of photoelectricity encoder is much , and it can increase control cost.
