Portable kiwi fruit internal quality nondestructive testing method and device

Abstract

The invention discloses a portable kiwi fruit internal quality nondestructive testing method and a portable kiwi fruit internal quality nondestructive testing device, and belongs to the field of spectrum nondestructive testing. The technical problem to be solved is to provide a low-cost, real-time and accurate portable kiwi fruit internal quality nondestructive testing method and device. The device structurally comprises a light shield, a detection probe, a support, a control processing module, a wireless communication module, a key fixing shaft, a measurement key, a lithium battery, a function key, a display screen, a shell and a correction white board. The measuring button is pressed down, the detection probe emits light at a specific angle to enter the kiwi fruit, light signals reflected by the kiwi fruit in a diffuse mode are converted into electric signals, the control processing module processes and calculates the electric signals to obtain a result, and the result can be displayed on the display screen in real time and sent to a remote database through the wireless communication module. The method is of great significance to quality inspection links such as kiwi fruit planting, grading and traceability.

Description

technical field [0001] The invention relates to the field of spectral nondestructive testing, in particular to a portable nondestructive testing method and device for internal quality of kiwi fruit. Background technique [0002] Kiwi fruit is tender and juicy, rich in nutrition, and has a unique and delicious taste, which is deeply loved by consumers. my country's kiwifruit planting area is the largest in the world. With the improvement of living standards, consumers' demand for kiwifruit has gradually changed from "quantity type" to "quality type". People pay more attention to the internal quality of kiwifruit. The main indicators to measure the internal quality of kiwifruit are sugar content, acidity value, and hardness value. . The traditional internal quality inspection method of kiwifruit is destructive inspection, which is only suitable for sampling inspection. Therefore, it is necessary to provide a portable kiwifruit internal quality non-destructive detection devi...

AI Technical Summary

Problems solved by technology

The problem with this method is that: the acquisition of spectral data is a spectrometer, which is expensive; the device only realizes the detection of the sugar content of a single internal quality of kiwifruit; the structure design of the instrument is not compact enough and the volume is large, which brings inconvenience to actual use

The problems of this method are: the spectral collection does not include the visible light part, and the internal quality characteristic information of the fruit contained in the visible light is not considered, which reduces the detection accuracy; the spectral data is acquired by a spectrometer, which is expensive; the construction of the experimental platform and the spectral data The collection needs to be completed by professional and technical personnel, and the operation steps are complicated; the detection device is large in size and requires a PC for data processing, which is not suitable for on-site carrying detection

[0005] To sum up, most of the non-destructive testing devices for fruit internal products at this stage use commercial spectrometers as spectral detectors, which have problems such as high detection costs and large detection systems
