Data adding method, device and detection equipment of a substance detection database

Abstract

Embodiments of the present invention relate to a method, device and detection equipment for adding data to a substance detection database. The method includes: obtaining spectral information of the substance and the components and proportions of the substance; if the substance is a mixed substance, and at least one component spectral information of the substance is unknown, obtaining information about the substance based on the substance The equation of the spectral information of each component in the above-mentioned substance; if the spectral information of the component whose spectral information is unknown in the above-mentioned substance is obtained through the above-mentioned equation, the spectral information and its corresponding components are added to the preset single-substance database. The preset single substance database stores at least one single substance and spectral information of the single substance. The embodiment of the present invention provides a new method for expanding the single-substance database, which avoids the work of searching for the single-substance and its spectral information, and saves the input of manpower and material resources.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of substance detection, for example, to a method, device and detection equipment for adding data to a substance detection database. Background technique [0002] In recent years, the application of substance detection equipment has become increasingly widespread, such as the detection of suspicious items in security inspections, the detection of drug ingredients by the Food and Drug Administration, and the detection of pesticide residues. In the current detection equipment, the method of confirming the composition of the substance through the spectrum has been widely used because it can detect the composition of the substance accurately and quickly. For example, a Raman detection device can determine the composition of a substance by acquiring the Raman spectrum of the substance and then comparing the spectrum with known spectra in a preset database. [0003] In the process of studying...

AI Technical Summary

Problems solved by technology

[0003] In the process of studying the prior art, the inventors found at least the following problems in the related art: in the method of detecting the composition of the substance by obtaining the spectrum of the substance, the establishment of the preset database is a key factor, but due to the tens of thousands of substances in nature , coupled with artificially synthesized substances, the number of real substances is huge

Adding such a large number of pure substances and their corresponding spectra to the preset database is a very time-consuming and labor-intensive task
