Abstract

The invention discloses a correcting system for online near-infrared detection on products through a packaging bag. The correcting system comprises a target detection component content correcting modeling unit and a target detection component correcting unit, wherein the target detection component content correcting modeling unit is used for establishing a target detection component content correcting model on the basis of a modeling sample; the target detection component correcting unit is connected with the target detection component content correcting modeling unit and is used for calculating a target detection component content of a to-be-detected sample on the basis of the target detection component content correcting model. The technical scheme is provided by the invention for solving the technical problem of test error caused by detection in the manner of separating the packaging bag when an online near-infrared instrument is used for quickly detecting large-scale products, so that the target detection component content of the to-be-detected sample outputted by the online near-infrared instrument can be prevented from being influenced by the error caused by the product package and the content can approach to the true value of the target detection component content of the to-be-detected product as far as possible.

Description

technical field [0001] The invention belongs to the field of analysis and detection, and in particular relates to a correction system and a detection method for near-infrared detection of products through packaging bags. Background technique [0002] The near-infrared spectrum is an electromagnetic radiation wave between visible light and mid-infrared. The American Society for Materials Testing defines the near-infrared spectral region as the region of 780-2526nm, which is the first non-visible light region discovered in the absorption spectrum. The near-infrared broad-spectrum region is consistent with the combined frequency of vibrations of hydrogen-containing groups (O-H, N-H, C-H) in organic molecules and the absorption regions of frequency multiplication at all levels. By scanning the near-infrared spectrum of the sample, the hydrogen-containing organic molecules in the sample can be obtained. The characteristic information of the group, and the use of near-infrared spe...
