烟箱缺条自动检测器设计

An autodetector for tobacco packing box lacking bars

分析了烟条装箱打包缺条的原因,指出常用的烟箱缺条光电检测设备的缺陷,设计了利用电容传感器、单片机和电压/频率转换器制作的检测器,并给出部分电路图和软件流程图。这种检测器能克服烟箱质量差别带来的影响,判断准确。

This paper analyses the causes of a tobacco packing box lacking bars and points out the defect of a general photoelectric detector.A new autodetector is designed to use a capacitive sensor and microcomputer technology.The relevant circuit and software are also presented in the paper.
