Abstract
In this paper, a new method to recognize the hydrocarbon is designed based on the fluorescence analyzing technology. It combines the fiber transducer technology and the fluorescence analyzing technology. It adopts a sphere fiber-optics probe to realize the highly active caption and transmission of the fluorescence signal of the hydrocarbon. The chargecoupled devices(CCD) is used to realize the high efficiency detection of the hydrocarbon fluorescence spectrum. It adopts the data acquisition system based on the complex programmable logic device(CPLD). The CPLD is controlled by the single chip to realize the high speed data acquisition. The experiment indicates that the system has a minimum detecting limit of the density is 0.03ppm when the excitation wavelength is 330nm and the emission wavelength is 400nm. It has a good linear relationship in the range of 0.0- 90ppm for the density of the hydrocarbon and The linear correlation coefficient r is 0.9986. It can realize the detection of the fluorescence of the hydrocarbon effectively.
