摘　　要：文中基于紫外诱导荧光技术设计岸基式传感器及其荧光滤光装置,实现海面油膜的探测并且克服传统监测系统的缺点。采用大连凌水码头的海水和6种不同的油样进行室内实验,实验结果表明6种油样的荧光光谱在300~400 nm范围内,相对荧光强度明显高于纯海水。利用光电倍增管作为荧光探测单元进行室外试验,结果表明该传感器能够有效地探测海面不同油种的薄油膜。通过现场测试验证,该传感器系统可作为一种岸基式的海面溢油预警监测装置。Based on the ultraviolet induced fluorescence technology,this paper designed the shore-based sensor and its fluorescence filter device to realize the detection of oil film on the sea surface and overcame the shortcomings of the traditional monitoring system.Conducting indoor experiments using seawater from the port of Lingshui and six oil samples of different types,the results showed that the fluorescence spectra of six oil samples were in the range of 300~400 nm,and the relative fluorescence intensity was significantly higher than that of pure seawater.We found that six oil samples relative fluorescence intensity was significantly higher than that of seawater in the range.Outdoor experiments with photomultiplier tube as a fluorescence detection unit show that the sensor can effectively detect thin oil film of different oil species at sea surface.Through field test and verification,the sensor system can be used as a shore-based oil spill warning and monitoring device.
