摘要近年来，随着工业的发展，油污对水体的污染日趋严重，甚至可能影响到饮用水源从而对我们的健康产生影响，所以工业排放污水的检测越来越受到重视。而如何实时在线检测水中油污相关参数也是行业中一直在研究优化的问题。69186

由于能力有限，故本套系统只能进行油污种类的鉴别。

如今国际上常用的油污检测方法有紫外法、红外法、重量法、荧光法等。其中荧光法灵敏度较高，选择性较强。本文利用了荧光法，选用发光二极管作为光源，光电二极管作为检测装置，采用51单片机作为处理器设计了一套工业油污检测系统。

本文的主要研究内容包括：

首先细致的分析了荧光的理论常识，并且分析了影响荧光强度和波长的各类因素，为随后检测系统的构建打下的理论基础。

随后，叙述了整个油污检测系统的设计思想，着重介绍了检测系统的设计思路。对构成系统的关键元件如何选择作了论述，结合程序进行更进一步的解释分析，并对系统中关键电路加以分析使得整个系统工作原理更加明了。

最后将系统中所用到的主要程序列举出来，说明编程思路和目的。

The Design of Industrial Oil Detection System

Abstract

Recently, with the development of industry, oil pollution of water bodies becoming more serious and can even affect the sources of our drinking water so that the oil pollution may have an impact on our health, so sewage industrial emissions detected more and more attention. and how to achieve real-time online detection of oil in water concentrations in the industry has been studying the optimization problem.

Today, oil detection methods commonly used internationally have ultraviolet, infrared method, gravimetric method, fluorescence method. Fluorescence has the highest sensitivity and selectivity also wider. In this paper, we use the fluorescence method and make a decision that use emitting diode as a light source and the photodiode as a detector. Using MSC51 to realize intelligent control to set the industrial oil detection system.

The main contents of this paper are as follows:

Firstly, making a detailed analysis of the theoretical knowledge fluorescence. Analysis the various factors that affect the fluorescence intensity and wavelength and provide a basic for the following construction of detection system.

Then, we discussed the design ideas of the entire oil detection system, especially the design ideas detection system. Making a discourse about how to choose the key components of the overall system and make a further explanation about them combining with the program. To make the working principle of the whole system simple and clear, we also make a detailed analysis about main circuit in the system.

Finally, listed the programs used in the system, illustrating programming ideas and purposes.

The paper has 23 pictures,18 references.
