System capable of rapidly detecting fruit and vegetable freshness and refrigerator

Abstract

The invention discloses a system capable of rapidly detecting fruit and vegetable freshness. The system comprises an image acquisition module, an information processing module and a result output display module, wherein the image acquisition module comprises a spectrometer, a light source and an area-array camera, the spectrometer is used for emitting lights with certain wavelength, the area-array camera is used for shooting a spectral image, the light source is used for lighting, the image acquisition module is used for acquiring image information of food and transmitting the image information to the information processing module, a fruit and vegetable freshness database is built in the information processing module, and the information processing module compares the received image information with the fruit and vegetable freshness database and provides a result for the result output display module to be displayed after the result is obtained. Compared with the prior art, the system disclosed by the invention has the advantages that a spectrum technology is adopted for carrying out freshness detection on fruits and vegetables in a refrigerator, rapid non-destructive detection can be carried out on the fruits and vegetables in the refrigerator, a detection result is fed back to a user, the result is accurate, and speediness and convenience are realized.

Description

technical field [0001] The invention relates to the technical field of refrigeration household appliances, in particular to a system for quickly detecting the freshness of fruits and vegetables and a refrigerator. Background technique [0002] Fruits and vegetables are indispensable foods in life. The indicators that consumers pay attention to when buying fruits and vegetables include nutrition, appearance, taste, freshness, price and safety, etc., and their quality and safety have always been hot issues of social concern. At present, the quality and safety of fruits and vegetables are mainly carried out manually, which has problems such as strong subjectivity, low detection efficiency, poor consistency of test results, and easy fatigue of test personnel. Conventional physical and chemical detection methods have disadvantages such as complex and cumbersome pretreatment, time-consuming and labor-intensive detection process, high detection cost, need to destroy samples, and in...

AI Technical Summary

Problems solved by technology

In addition, some refrigerator manufacturers have applied for patents for detecting food freshness through odor sensors. This method is not feasible. On the one hand, odor sensors can only target one type of gas, and the types of food that can be detected are limited. It is easy to passivate and the sensitivity is reduced; on the other hand, the price of the odor sensor is high, so it is difficult to apply it in large quantities in the refrigerator
