Abstract

The invention discloses an automatic online near infrared spectrum detecting device and a control method. The device comprises two parts, namely, an automatic sample feeding system and a near infrared spectrum acquisition system, wherein the automatic sample feeding system comprises an intermittent sample feeding mechanism and a sample rotating mechanism which is positioned above the intermittent sample feeding mechanism; the near infrared spectrum acquisition system comprises a diffuse reflection and diffuse transmission integrated acquisition light path and a light source adjustment and control mechanism thereof. The invention innovatively provides that two acquisition modes for diffuse reflection and diffuse transmission are integrated in one spectrum detecting device; multi-station automatic feeding is provided; the adjustability of the angle of a light source and the rotation of a sample to be detected are realized; the online detecting efficiency of a spectrograph is improved; comprehensive sample spectrum acquisition information can be obtained; great convenience is provided for scientific research and production.

Description

technical field [0001] The invention relates to the optical non-destructive detection of the quality and safety of agricultural products, in particular to a near-infrared spectrum automatic sampling online detection device and a control method integrated with diffuse reflection and diffuse transmission. Background technique [0002] In recent years, spectral detection technology has developed rapidly, and its application has also expanded to various fields. However, at present, spectral detection devices generally adopt a single spectral acquisition mode (reflection or transmission), and there is no detection instrument that integrates two spectral acquisition modes at the same time; the existing sampling methods of spectral detection instruments mostly use manual single sampling, In particular, the spectral detectors used for scientific research and teaching have not realized automatic sampling and online detection. At the same time, the existing instruments basically coll...

However, at present, spectral detection devices generally adopt a single spectral acquisition mode (reflection or transmission), and there is no detection instrument that integrates two spectral acquisition modes at the same time; the existing sampling methods of spectral detection instruments mostly use manual single sampling, Especially the spectroscopic detectors used for scientific research and teaching have not realized automatic sampling and online detection

At the same time, the existing instruments basically collect the spectral information of a single region for the spectral collection of the sample, which is not comprehensive for obtaining the spectral information of the sample to be tested. To collect the spectral information of multiple regions of a single sample, the sample needs to be converted manually. position and then re-collect spectral information, which will inevitably bring great inconvenience to the collection work
