Online fruit detection device and use method thereof

Abstract

The invention relates to an online fruit detection device and a use method thereof. The online fruit detection device comprises a spectrograph mechanism, an automatic control mechanism and a driving mechanism, wherein the automatic control mechanism comprises a controller, an image acquisition unit, an image processing unit, an image storage unit and a driving mechanism control unit, the driving mechanism comprises a fruit cup, a transmission mechanism and a rotary driving piece and / or a fruit unloading driving piece, the controller controls the driving mechanism control unit to make an instruction of opening and closing the driving mechanism according to a comparison result and / or a judgment result, and the driving mechanism control unit controls the driving mechanism to rotate or not rotate fruits on the fruit cup according to the received instruction, and to unload or not unload the fruits. The device has the characteristics of reasonable structural design, convenience in operationand use and high detection accuracy, and can ensure that the spectrograph can accurately acquire fruit spectral data in the fruit detection process by combining image detection and mechanical motion control, so that the detection accuracy is greatly improved.

Description

technical field [0001] The invention relates to the technical field, in particular to an online fruit detection device and a method for using the same. Background technique [0002] The online non-destructive testing technology for the internal quality of fruits is developing rapidly, but there are still difficulties, mainly in that most of the fruit tests are correct, but there are also phenomena where the measurement accuracy is not high. Except for the reason of the mathematical model, the most important point is that the intensity of the absorbed light is inconsistent, which can easily lead to inaccurate detection accuracy. [0003] When the fruit receives the light from the light bulb, it will introduce the spectrum through the optical fiber for data collection, analysis and statistical calculation. Because the fruit stalk or fruit pedicle is opaque or black in color and blocks light, when the fruit stalk or fruit pedicle directly faces the optical fiber collection hol...

AI Technical Summary

Problems solved by technology

Due to the opaque or black color of fruit stalks or fruit pedicles that block light, when the fruit stalks or fruit pedicles directly face the optical fiber collection hole of the spectrometer, the absorption of light by the spectrometer is inconsistent with the light collected by other parts of the fruit facing the fiber optic hole. Cause spectral absorption intensity or information difference, make data inaccurate and cause inaccurate detection that requires fruit spectral data (such as fruit sugar content, acidity, detection of various internal diseases and insect pests)
