本文介绍的光电开关将发射和接收、光学和电路都装在一个壳体内,利用不同颜色在光照下所反射的光强弱不同,辨色光电开光所接收到的电信号强弱也不同,从而区别出七色色标。通过对各种颜色的鉴别达到定位、校正和计数的目的。文章简要介绍了这种光电开光的光学系统、电路系统和应用实例。 This paper describes the photoelectric switch will launch and receive, optical and electrical circuits are housed in a shell, the use of different colors in the light of the reflected light intensity is different, the color photoelectric light received by the electrical signal strength is different, so that Differentiate the seven-color color scale. Through the identification of various colors to achieve positioning, calibration and counting purposes. The article briefly introduces the optoelectronic optical system, circuit system and application examples.
