Embodiment 2

[0024] Example 2 Application of the present invention in identifying imperfect rapeseeds

[0025] The specific design of the present invention refers to the "Summary of the Invention" and the "Description of the Drawings". The online detection of single-seed rapeseed imperfect grains (including moldy, immature, and heat-damaged grains) is taken as a specific implementation mode, and the description of the present invention The embodiment is further described.

[0026] Depend on Figure 1 to Figure 2 Shown: When detecting single rapeseed imperfect kernels, select representative imperfect kernels (including moldy, immature, and heat-damaged kernels) and normal kernel samples to form a modeling sample set. The sample grains used for modeling are put into the sampler sample chamber 21 on one side of the sampling disk 18, and fall on the bottom of the sampler sample chamber, and a negative pressure is opened in the sampler air chamber 12 on the other side of the sampling disk 18. ...

Abstract

The invention belongs to the field of agricultural detection equipment and detection technology and discloses a single grain rapeseed quality near infrared spectrum on-line nondestructive testing method and a single grain rapeseed quality near infrared spectrum on-line nondestructive testing device. The single grain rapeseed quality near infrared spectrum on-line nondestructive testing device comprises a spectrum signal acquisition optical fiber, a spectrum acquisition controlling photoelectric sensor, a single grain sampling device, a near infrared spectrometer, an incidence optical fiber, a light source, a motor, a negative pressure pipeline, a positive pressure pipeline, a positive pressure fan and a computer. The single grain rapeseed quality near infrared spectrum on-line nondestructive testing method comprises the following steps that: according to rapeseed quality indexes required to be tested, spectral information of a single grain rapeseed sample is acquired in an online manner, and physical / chemistry tests are performed on qualities to be tested of single grain rapeseeds, and a single grain rapeseed quality detection model of spectral information is constructed; in online detection, the spectral information of the single grain rapeseed sample to be tested is automatically acquired, and the single grain rapeseed quality detection model is utilized to perform real-time online nondestructive testing on the indexes to be tested of the sample to be tested. According to the single grain rapeseed quality near infrared spectrum on-line nondestructive testing method and the single grain rapeseed quality near infrared spectrum on-line nondestructive testing device provided by the invention, through using the optical properties of rapeseeds, and based on the combination of a pneumatic-type automated single grain sampling method, automated online detection of single grain rapeseed qualities can be realized.

Description

technical field [0001] The invention belongs to the field of agricultural detection equipment and detection methods, in particular to a method for on-line detection of grain quality of grain and oil crops and a special device thereof, and is related to the field of near-infrared spectrum non-destructive detection. Background technique [0002] my country is one of the main rapeseed producing countries in the world, with an average planting area of ​​about 6.9 million hectares from 2001 to 2010, and a total rapeseed output of about 12 million tons, accounting for about 30% of the world's total. Rapeseed contains erucic acid, linolenic acid, oleic acid, linoleic acid, protein, glucosinolates, etc. It is the main source of edible vegetable oil and plant protein cake for feed in my country; it is also an important source of biodiesel, industrial and medical oils . [0003] The composition content of different varieties of rapeseed is quite different, and the composition of rapes...
