[Abstract]:21th century is the century of the ocean. The exploitation and utilization of the ocean is of great significance. In order to develop and utilize the ocean, we must first protect the ocean, because the ocean is the cradle of life. With the development of the world economy, More and more marine oil and gas resources are exploited and utilized. Ocean transportation is the main way of oil transportation, and various kinds of oil are also the main power source of ocean transportation. Marine oil pollution has become one of the main sources of marine pollution, which has affected the marine ecological environment. In order to achieve timely and accurate treatment of marine oil spills, it is necessary to monitor oil spills on the sea. In order to reduce the loss and harm caused by the accident, the non-contact fluorescent oil spill monitoring equipment is designed, and the ordinary xenon lamp light source is used instead of the laser, and the relevant staff are informed of the specific location and meteorological information of the oil spill area in time, so as to reduce the loss and harm caused by the accident. Using physical and software methods to realize environmental light filtering, and based on the principle of peak fluorescence capture, the effective real-time monitoring of oil spill on the sea surface is realized. The main problems and related techniques are: 1) Analysis of oil detection method based on fluorescence method, Firstly, the present situation of oil spill detection at home and abroad is analyzed, and various oil spill detection methods are compared. It is determined that fluorescence method is used for detection. Because the fluorescence generation method based on laser and the fluorescence detection method based on spectrometer are not suitable for field detection, In this paper, the non-laser fluorescence excitation and non-spectrometer fluorescence detection method. The key problems in the system design are solved by using the combination of xenon lamp and filter to build a simulated laser emission path, which solves the problem of the excitation source of fluorescence: using the combination of photomultiplier tube and filter, The primary filtering of environmental light and the photoelectric conversion of fluorescence are solved, the peak capture circuit is designed and built, the problem of peak fluorescence capture is solved, and the hardware and software cooperate with each other for the development of the equipment. To complete the hardware design of the system, STM32F107 is used as the main control unit, and the ultrasonic ranging module is combined with the GPS / GPRS module. Acousto-optic alarm lamp and other peripheral devices are used to monitor and alarm oil spill on the surface of water. In software, embedded lower computer software is designed based on 渭 C / OS 鈪,
