摘要
介绍了一种基于紫外荧光分析法的水中油类污染物的检测传感器的设计。重点介绍了该传感探头的检测部分和控制部分的设计,检测部分由紫外发光二极管和探测器等组成信号采集装置,控制部分通过采用运算放大器、滤波器以及模数转换器实现了对微弱信号的高精度放大和处理。紫外荧光分析法具有快速、非接触性检测、操作简单、绿色环保无污染等优点,结合单片机技术在工程上有广泛应用。
An on-line oil-in-water monitoring probe based on ultraviolet fluorescence spectrophotometry was introduced. This paper focused on detecting system and control system of the probe. The detecting system included an ultraviolet LED and a photodiode,combined with related components, which acted as signal pickup assembly. The control system contained operational amplifier, low pass filter and analog to digital converter （A/D）, which operated the weak signal. Ultraviolet fluorescence analysis technique is a kind of fast,simple,non-contact testing,environment-friendly method,and it could be widely applied in engineering if it is combined with single-chip microcomputer technology.
