Oil Spill Thickness Sensing Technology Based on Electromagnetic Energy Absorption

在石油生产与运输过程中，溢油事故经常发生，往往对海洋环境和经济造成十分恶劣的影响．通过对油污 厚度实时监测可及时发现溢油并定位溢油来源．基于电磁能量吸收机理，推导了油污厚度与电磁能量吸收率之间的 数学模型，设计了传感器结构，搭建了油污厚度检测的实验平台．实验结果表明，接收到的电磁能量功率与油污厚 度间存在线性关系，传感器的检测分辨率可达 0.07,mm，持续工作情况下测量时会产生最大 0.57,mm 的误差，相当 于满量程的 1.4%，为海洋油污检测传感器的设计提供了理论基础和实验参考．
Oil spill occurs frequently in the oil production and transportation process. Marine oil pollution often has a very bad impact on the marine environment and economy. Real-time monitoring the thickness of oil can detect and locate the source of oil spill. Based on electromagnetic energy absorption mechanism，the mathematical model of the relationship between oil thickness and electromagnetic energy absorption rate was established in this paper. Then the sensor structure we designed，and an experimental platform for detecting the thickness of the oil were built. Experi- mental results show that reception power has a linear relationship with oil thickness，and that detection resolution of the sensor is up to 0.07,mm. Continuous work will produce a maximal measuring error of 0.57,mm，which represents 1.4%FS(full scale). The study in this paper provides a theoretical basis and experimental reference for the design of marine oil pollution detection sensor
