Method and system device for detecting commodity according to spectral information of substance

Abstract

The invention provides a method and a system device for detecting a commodity according to the spectral information of a substance. The method comprises the following steps of: carrying out spectral measurement on a commodity sample by adopting a spectral means, establishing a spectral database and carrying out mark registration for the commodity sample; issuing an identity identification mark, such as a one-dimensional bar code, a two-dimensional bar code and a radio-frequency identification label (RFID), to the registered commodity; storing sample spectral information, measurement condition information and commodity information of the sample per se by utilizing the identity identification mark of the commodity; and setting a testing system by recognizing and reading the identity identification mark of the target commodity and utilizing data, such a read measurement condition and the like, so as to carry out spectral measurement on the target commodity under the same testing means, and carrying out comparative analysis on the obtained spectral information of the target commodity and the corresponding sample spectral information of the commodity. Thus, the invention can be used for effectively acknowledging whether an onsale commodity conforms to the quality of the registered sample or not and simultaneously can be used for detecting some unauthorized substances.

Description

technical field [0001] The invention relates to a method and a system device for detecting commodities according to spectral information of substances. More specifically, the present invention mainly relates to the use of spectroscopic analysis method to establish a spectral database in commodities based on samples in advance, by detecting target commodities and comparing them with the spectral database, and by judging that the spectra of target commodities are relative to their corresponding Whether the sample spectrum changes to identify the target product and verify the target product. Background technique [0002] Food and drug safety are issues that are highly valued worldwide. The scope of food and drug safety testing is very wide. For food, it is mainly to analyze the harmful substances and additives in the food, so as to judge whether the content of harmful substances and additives in the food meets the national safety standards. Drugs or other products face much t...

Problems solved by technology

[0005] At present, various spectroscopic analysis techniques and equipment are basically limited to the scope of application in the laboratory. Even some portable equipment, such as portable infrared and portable Raman, have low resolution due to their small size (the focus of spectroscopic equipment Length is limited), and because of the portability, only a simple refrigeration and cooling CCD can be used as a detection method, resulting in a low signal-to-noise ratio. When analyzing a mixture, the low detection limit makes it difficult to effectively identify the product to be inspected
