Problems solved by technology

[0003] However, the near-infrared spectrum analysis in the prior art generally only analyzes the near-infrared spectrum of urea, and determines the content of each component of urea or the corresponding data indicators according to the near-infrared spectrum
The analysis close to the infrared spectrum alone may make the detection of various indicators of urea inaccurate, and the detection accuracy is not high

Abstract

According to a urea detection and analysis method and device based on near-infrared modeling, the near-infrared detection value of a urea sample and the wet chemical value of each component can be combined and associated, then a corresponding database is constructed, and an near-infrared analysis model is formed, so that the near-infrared analysis model can be used for detecting and analyzing the content data of each component of the to-be-detected urea, and the accuracy of the content of each component obtained by detection is effectively improved.

Description

technical field [0001] The present disclosure relates to the technical field of oil product detection, in particular to a near-infrared modeling-based urea detection and analysis method and device. Background technique [0002] Near-infrared spectroscopy has been widely used in the analysis of oil properties. Compared with traditional laboratory testing methods, this method has the advantages of fast analysis speed, high precision and low cost. [0003] However, the near-infrared spectrum analysis in the prior art generally only analyzes the near-infrared spectrum of urea, and determines the content of each component of urea or the corresponding data index according to the near-infrared spectrum. The analysis close to the infrared spectrum alone may make the detection of various indicators of urea inaccurate, and the detection accuracy is not high. Contents of the invention [0004] In view of this, the purpose of the present disclosure is to propose a method and device f...
