论述了一种高可靠、低运行成本、光学非接触式的基于紫外光诱导荧光码头溢油监测的方法。通过对润滑油、柴油紫外光诱导荧光光谱的探测确定了以360 nm 附近的荧光峰值作为溢油监测的特征峰，设计了用于码头溢油监测的原理样机。通过对不同探测距离下荧光信号强度及误差的测量发现二者有较好的线性关系，讨论了影响系统测量误差的主要因素，并通过滑动平均的方法提高了系统的信噪比。本系统油膜探测灵敏度达微米量级，可以实时监测超标排放或意外泄漏的碳氢化合物，并在污染事态扩大之前及时报警通知相关部门做出反应，是溢油监测研究的一大进步。

A method of an oil spill detection system is discussed which provides reliable, economical, optical, noncontact, hydrocarbon pollution detection technique. System uses the fluorescence wave crest around 360nm as the character of oil spill on the water, which is found through the fluorescence spectra of lubricating and diesel oil detected through experiments. A proto type is designed and tested. The error which is linearly proportional to the distance can be reduced by moving average. System achieves Micron-level sensitivity for a comprehensive range of oils and can detect hydrocarbon releases in real-time. This system can be used for containing and preventing accidental discharges of hydrocarbon-based pollutants and making early warning of pollution before the environment are damaged. It is a great progress in the study of oil spill detection field.
