Automatic code reading device and automatic code reading method of sulfanilamide type medicine residue detecting reagent strip

Abstract

The invention discloses an automatic code reading device and an automatic code reading method of a sulfanilamide type medicine residue detecting reagent strip and relates to the field of sulfanilamide type medicine residue detection. The method comprises the following steps that 1, materials are prepared; 2, the reagent strip is placed in an illumination box of the device, and images are collected through a charge coupled device (CCD) camera and an image collecting card; and 3, data is recorded through a computer, and images are processed according to the following steps that A, collected colored images are converted into gray level images; B, the gray level images are enhanced; C, the characteristic parameters of the gray level images are extracted; and D, the characteristic parameters are substituted into a back propagation (BP) neural network recognition model, and the sulfanilamide type medicine residue concentration is judged through peak height detection. The machine vision technology is adopted, and the automatic code reading can be completed, the standards are unified, the judgment is accurate, the computer is used for processing images, the efficiency is high, a machine is used for replacing the human eyes, the requirements of the modern automatic detection industry can be met, and good application and popularization prospects are realized. The sulfanilamide type medicine concentration can be fast and accurately detected.

Description

technical field [0001] The invention relates to the field of detection of sulfonamide drug residues, in particular to an automatic code-reading device for detection reagent strips of sulfonamide drug residues and a method thereof; The bar reacts with sulfonamides in different colors, and the machine vision system is used to quickly and accurately detect the presence and concentration of sulfa drugs, which provides a fast and effective detection method to prevent food with excessive sulfonamide content from entering the market . Background technique [0002] Sulfonamides (SAs for short) are a class of artificially synthesized antibacterial drugs that are widely used in animal husbandry. However, due to the unreasonable use of SAs, SAs remain in animal-derived foods and enter the human body through the food chain, which can cause adverse reactions in the human body and have potential carcinogenicity, which poses a potential threat to human health; such as increasing the conce...
