Embodiment Construction

[0035] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0036] Examples, figure 1 Schematically shows the flow chart of the marine oil spilled oil species identification method disclosed in the present invention.

[0037] First, collect a sample library of various oil types, especially gasoline, diesel, kerosene, motor oil, crude oil, and edible oil such as peanut oil. First, detect the main components and their contents according to the method of chemical separation. For example, for crude oil, it mainly detects hydrocarbons, gums, asphaltenes and their content, and for finished crude oil, the group should detect its main components, alkanes, nap...

Abstract

The invention discloses an ocean oil spill fine telemetering method based on blind source separation. The method includes three processes: a multichannel telemetering system, a mixed spectrum blind signal separation method and spilled oil type recognition method. In the method, a multichannel spectrum observation signal X of a spilled oil sample is obtained through the telemetering system. In the mixed spectrum blind signal separation method, through a quick independent component analysis method, the multichannel spectrum observation signal X is subjected to blind signal separation to obtain a spectrum Y of a plurality of mixed components in the channels respectively, wherein the spectrum Y is the approximation of the main component S in the spilled oil sample and includes hydrocarbons, colloids, asphalts and the content information thereof. The spilled oil type recognition method includes the steps of measuring the characters of the component spectrum, matching the characters of the component spectrum with the spectrum characters of the components in a pattern bank, and further correctly recognizing the components and the contents of the spilled oil. By means of the three steps, the types and the components of the spilled oil can be accurately analyzed, thereby quickly identifying illegal oil spill sources.

Description

Technical field [0001] The invention relates to a method for identifying marine oil spill sources used in the environmental field, in particular to a refined remote measurement method for marine oil spill based on blind source separation. Background technique [0002] In recent years, marine oil spill accidents have occurred frequently. It is a complex and challenging task to analyze and identify oil spills in a timely and accurate manner, determine responsibility, trace the source of illegal oil spills, and take appropriate emergency response. . The current oil spill identification standard (GB / T21247-2007) is mostly represented by laboratory chemical identification methods represented by liquid chromatography / mass spectrometry. Although the oil can be accurately analyzed, the detection speed is slow and expensive. [0003] At present, the detection of oil spills is mainly achieved through satellites or airplanes, through SAR or optical remote sensing, and is affected by the reso...
