Embodiment Construction

[0035] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0036] The invention provides a spectrum identification method for spectrum model transfer, such as figure 1 As shown, the main steps are as follows:

[0037] I. Classification of sample spectra

[0038] The spectral analysis instrument is divided into a host and a slave. The host collects the reference values ​​of the spectral data of m samples, and the slave collects the spectral data and reference values ​​of L samples among the m samples, where m>L. The sample data in the slave machine is a subset of the master machine, and the sample set is called the reference set; the sample set in the master machine except the reference set is called the prediction set.

[0039] II. Pretreatment of sample spectra

[0040] Perform baseline correction, spectral sampling or interpolation on the spectral data of the host and slave to obtain sample spectra with consi...

Abstract

The invention provides a spectrum identification method for spectrum model transmission. The method comprises the steps of classifying sample spectrums of a host and a slave, establishing a spectrum transmission model, carrying out spectrum correction on samples in a host prediction set, and substituting the corrected samples into the slave to obtain sample component and content results. According to the method, the difference of different spectrum instruments in different environments is effectively eliminated, the host spectrum is communicated with the slave, and the workload of analyzing, testing and establishing a standard sample spectrum library is reduced; and compared with a traditional method, the method provided by the invention has the advantages that the required parameters and data volume are small, and the correction accuracy is high.

Description

technical field [0001] The invention belongs to the technical field of spectrum analysis, and in particular relates to a spectrum recognition method for spectrum model transmission. Background technique [0002] Spectral analysis technology is developed on the basis of chemical detection, computer science and other disciplines, and has been more and more widely used in food testing, drug testing, oil product testing, etc., and is called a hot technology in the field of chemical analysis. [0003] In the practical application of spectrometers, there are structural differences among various spectrometers from different manufacturers and models, and even the same kind of instruments have unavoidable spectral differences under the influence of different use environments. Therefore, when synchronizing the spectral data and sample spectral library of multiple spectroscopic instruments, it is necessary to establish a spectral model to realize the intercommunication of spectral data...
