Dual-light path fruit nondestructive detection system and method based on near infrared spectrum

Abstract

The invention discloses a dual-light path fruit nondestructive detection system and method based on near infrared spectrum, and belongs to the technical field of the near infrared spectrum nondestructive detection. The system comprises a power module, an LED light source, a light path module and a circuit module connected in order; the power module supplies power for the LED light source, the LEDlight source produces the near infrared spectrum to enter the light path module; the light path module divides the near infrared spectrum into two paths: one path is used as reference to be collected,and the other path is used for performing irradiation collection on a to-be-detected object, two paths of collection data are transmitted into the circuit module; the circuit module corrects the collection data and then stores the same. The problems that the absorption spectrum of the to-be-detected object is hard to be accurately reflected and the detection cannot be quantitatively output sincethe light source jittering influence is existent in the near infrared spectrum fruit nondestructive detection equipment, and the use scene limitation is large and the use method is tedious are solved.

Description

technical field [0001] The invention belongs to the technical field of near-infrared spectrum nondestructive detection, and relates to a near-infrared spectrum-based dual-light path fruit nondestructive detection system and method. Background technique [0002] my country's fruit cultivation has a long history and abundant resources. Fruits have become the third largest planting industry in China. my country's fruit output ranks first in the world, while the fruit storage capacity is only 10%. Compared with developed countries, my country's fruit processing level is low, the rotten fruit rate is high, and the detection and sorting technology is backward, resulting in the uneven quality of the same batch of fruits and lack of competitiveness in the world market. The traditional manual sorting method has low efficiency, high error rate, and high labor intensity. Therefore, it is extremely necessary to develop a non-destructive, simple, efficient, and high-accuracy fruit detect...
