纱线检测中光电传感器及其前置放大器设计
摘要
针对当今纱线检测中"色纱疵"难以检测的问题
设计了一种新型的光电传感器。通过专门的反射光检测通路感知由纱线反射回来的光强的变化
根据接收到的光强变化
判断有无纱疵。设计了前置放大电路
通过实验验证了该系统的可行性。
Abstract
To slove the problem of detecting different color yarn defects
a new type of optoelectronic sensor which has a reflected light detect channel is designed to receive the reflected light.The yarn defects are detected by the light change from the yarn pre-amplifier circuit is designed and the system is proved reflected feasible by test.
