Identification and analysis system for jewelry jade and rock minerals

Abstract

The invention provides an identification and analysis system for jewelry jade and rock minerals. The identification and analysis system comprises a detection system, a spectrum analysis system, a database and a result display system, wherein jewelry jade to be detected is detected by the detection system so as to obtain detection data, then the detection data flows to the spectrum analysis system, comparison is carried out by the spectrum analysis system to obtain a result, and then the result is transmitted to the result display system; the detection system is an infrared spectrometer; the spectrum analysis system comprises 400-1500 cm<-1> fingerprint region analysis, 150-4000 cm<-1> group frequency region analysis and near-infrared region 4000-7500 cm<-1> analysis. The system provided by the invention has the advantages that testing wave bands and testing methods (transmission method, reflection method and compression method) are expanded in the transverse direction, a data spectrogram base is established in the longitudinal direction, a set of system is formed from the detection and analysis of samples and presentation of result, the detection can be efficiently completed in a time-saving and labor-saving manner, and the accuracy of jewelry jade is improved; meanwhile, new information of jewelry jade can be added at any time.

Description

technical field [0001] The invention relates to a jewelry identification system, more specifically, to an identification and analysis system for jewelry, jade and rock minerals. Background technique [0002] KW-IR infrared spectrum database system (project year number: 0900322985) This system is the first mineral infrared spectrum computer retrieval system established in China. It uses PE-783 infrared spectrometer 00 computer and uses BASIC language to create 630 mineral infrared spectrum maps. The 4000-400cm-1 wave number is coded into 27 sub-intervals, stored in the disk in the form of random data files, and the strongest peaks are retrieved from the spectrum data, and the peak-peak matching comparison is performed, and the number of judgments judged by the circular search according to the address code Similarity, so as to determine the mineral name.

AI Technical Summary

Problems solved by technology

[0008] 1. The KW-IR infrared spectrum database system applies to a relatively short spectral peak section, only 4000-400cm-1, covering incompletely

[0009] 2. The application of BJKF-1 portable near-infrared mineral analyzer in the identification of gemstones is the near-infrared light diffuse reflectance spectrum characteristics of minerals, which can only identify gemstone varieties, but cannot be identified by the optimized treatment of some gemstones

[0010] 3. The application of Fourier transform infrared spectroscopy and Raman spectroscopy in the identification of gemstones is just a brief introduction of the method by introducing the instruments
