基于单片机的光电式红枣分选技术研究

Optical Separating Technology of Jujube Based on MCU

提出了一种基于单片机的红枣分选技术,利用红枣遮挡光电传感器的光源时所引起的传感器输出电平的变化,来控制单片机对红枣通过传感器的时间进行计时,由通过的时间可以判断出其长度,在与预设的分级值对比后,单片机将做出是否将该枣分选出来的判断,从而达到分选的目的．

This paper presents a jujube separation technology based on MCU. When the light of photoelectric sensor is blocked by jujube, the output level of sensor changes, and the level changes can be used to control the timing of the passing time. According to the passing time, the length of juiube can be judged, compared with the preset value, MCU will make a iudgment whether or not to separate the jujube, so as to achieve the purpose of separation.
