Abstract

The invention discloses a portable type grape sugar degree near infrared detection device and method and relates to the field of nondestructive measuring methods of farm products. The method comprises the steps that (1) to-be-detected grapes are placed onto a detection port of a near infrared sampling module; (2) an LED lamp switch is switched on, and near infrared spectral information is acquired; (3) a corresponding mathematical model is selected, and acquired spectra are processed; (4) corresponding sugar degrees are displayed on a screen. The near infrared spectroscopy is used, and rapid nondestructive testing of the sugar degrees can be completed; the spectral information acquired by a spectral acquisition port which is designed by applying the rubber soft fitting characteristic is good in quality, and the signal-to-noise ratio is high; the model linearity is good, and the detection accuracy is high; the device is small in size, high in reliability, expendable and easy to update on the basis of an embedded system; the device structure is simple, the cost is low, and the spectrum technology can be widely applied; the device is easy to carry due to the small size, suitable for many scenes, easy to popularize and suitable for sugar degree detection.

Description

technical field [0001] The invention relates to the fields of near-infrared spectrum detection, computer science and technology, and non-destructive detection of agricultural products, in particular to a portable near-infrared detection device for glucose level and a method thereof. Background technique [0002] Spectral detection technology has been widely used in the field of non-destructive testing; it is also widely used in the detection of fruits and vegetables. The cultivated area and output of grapes in my country rank among the top in the world, and it has also become one of the most commonly planted fruit trees in the world. Due to its high economic value, it has spread to temperate and subtropical regions around the world [Chao Wuji. Adjustment, improvement, transformation and upgrading to promote the steady development of my country's grape industry [J]. Chinese Fruit and Vegetables, 2015, 09: 12-14.]. Although the output of fresh grapes in my country occupies th...
