A system comprises the refrigerating chamber, a multispectral imaging system, an electric-control sliding rail, a plurality of food storage boxes, a humidity control module, a central control module, a communication module, a touch screen displayer and a main control computer. The refrigerating chamber comprises a box body and a box door. The multispectral imaging system comprises a light source, a lens, an optical filter wheel and the multispectral imaging unit. According to the device for detecting various food states in the refrigerating chamber based on the single multispectral imaging unit, detection of the states of various types of food in the layered refrigerating chamber in a refrigerator is achieved through the single multispectral imaging unit, the limitation that imaging detection of food in the refrigerator can only be suitable for imaging of a single layer is overcome creatively, high cost and space waste caused by adopting a plurality of spectral imaging units for detection are avoided, and a feasible approach is provided for applying the technique of detecting the states, such as the freshness, of the food through spectral imaging to the refrigerator.

Description

technical field [0001] The present invention relates to a refrigerator refrigerating chamber device, in particular to a device for detecting multiple food states in a refrigerating chamber based on a single multispectral imaging unit. Background technique [0002] Spectral images contain rich image space information and spectral information, and have the characteristics of fast and non-destructive detection of many indicators of objects. Compared with the limitations of using odor sensors such as low sensitivity, less information, and blurred detection objects, using spectral imaging technology as a food detection technology has the advantages of being able to quickly identify food types, quantities, and corresponding freshness distributions. In recent years, more and more research results on food freshness based on spectral imaging detection technology have been published, especially for the freshness detection of fruits, vegetables, meat and other foods, showing that spect...

Problems solved by technology

However, the invention of a suitable refrigerator refrigeration system device to better apply the technology of spectral imaging to detect the freshness of food has rarely been mentioned.

[0003] Due to the requirements on the floor area and space utilization of the refrigerator, refrigerators generally store a variety of foods in layers, and because the cost of spectral imaging detection instruments is relatively high and requires a certain amount of space, multiple spectral imaging detection instruments are used. The system design to detect the freshness of food on each layer of the refrigerator will greatly reduce the cost performance of the refrigerator
