Baijiu adulteration detection system based on portable spectrometer

Abstract

The invention discloses a Baijiu adulteration detection system based on a portable spectrometer, wherein the Baijiu adulteration detection system comprises a spectrum detection module, a client and aserver, the client is interactively connected with the spectrum detection module, the client is interactively connected with the server, and the client sends a detection instruction to the spectrum detection module; the spectrum detection module collects spectrum data of Baijiu and transmits the spectrum data to the client, and the client transmits the spectrum data to the server; and an analysismodel is deployed on the server, the analysis model analyzes the spectrum data, and the server acquires an analysis result and transmits the analysis result back to the client. According to the invention, through cooperation of the spectrum detection module and the client, a user can carry out measurement anytime and anywhere; through cooperation of the client and the server, real-time analysis iscarried out, a result is fed back to the user, scanning detection, data analysis and result display are integrated, carrying is convenient, real-time detection can be carried out, and the Baijiu quality detection process is simplified.

Description

technical field [0001] The invention relates to the field of food safety detection, in particular to a liquor adulteration detection system based on a portable spectrometer. Background technique [0002] In recent years, food safety problems have occurred frequently, and alcohol adulteration, as a prominent problem in food safety, has received more and more attention. China's liquor consumption is large, and liquor also occupies an important position in the domestic and foreign liquor markets. Liquor adulteration is mainly divided into two categories, one is to add water to original wine, and the other is to mix industrial alcohol with original wine. Industrial alcohol contains impurities such as methanol, aldehydes, and organic acids. The toxicity of methanol is fatal, and its oral fatal dose is 300-1000mg / kg. Blending industrial alcohol in raw wine will not only affect the quality of liquor but also cause harm to drinkers . Therefore, it is very important to increase th...

Problems solved by technology

[0003] At present, the research on the detection of liquor adulteration mostly stays in the use of large-scale instruments to obtain accurate high-resolution spectral data. The maintenance cost is high, and the working conditions are harsh, and the quality inspection of liquor cannot be carried out anytime and anywhere

In recent years, with the wide application of portable and hand-held small spectrometers in various fields, there are also researches on the application of these small spectrometers to liquor detection, but at present, the quality detection based on these small spectrometers is often limited to the research of algorithms. Forming a small Internet of Things system for user interaction, users cannot perform real-time detection of liquor anytime, anywhere, conveniently and quickly
