Embodiment 1

[0029] This embodiment describes the structure of the present invention. combine Figure 1-3 , an intelligent constant temperature preservation control device, comprising a computer 1 and a storage cabinet 2, the computer 1 is connected to the storage cabinet 2; it is characterized in that:

[0030] The storage cabinet 2 is provided with a controller, a plurality of storage drawers 3, an infrared emitting device, an infrared receiving device, a gas circulation filter device, a plurality of refrigeration pipes, a compressor, an infrared light source 4, and an infrared spectrometer 5;

[0031] Each storage drawer 3 is provided with a plurality of fresh-keeping compartments 31, and each fresh-keeping compartment 31 is correspondingly provided with an infrared emitting head 41, an infrared receiving head 51, an air outlet, and an air inlet; Head 41; the infrared emitting head 41 can emit infrared light into the fresh-keeping compartment 31, and the infrared receiving head 51 rece...

Embodiment 2

[0041] This embodiment describes the control method of the device.

[0042] Step 1: Establish the food category identification model of infrared spectrum and food category and the correlation model of infrared spectrum and real-time temperature in computer 1;

[0043] Step 2: Establish a correlation model between the infrared spectrum corresponding to each food type, the suitable storage temperature, and the longest fresh-keeping time in the computer 1;

[0044] Step 3: the computer 1 sends a detection signal to the controller of the storage cabinet 2, and the controller controls the infrared light source 4 to emit infrared light into the fresh-keeping compartment 31, and the infrared light emission direction is aligned with a focal point of the ellipsoid compartment; each infrared receiving head 51 Receive the infrared spectrum reflected by the food in its corresponding fresh-keeping compartment 31 in turn, and send to the infrared spectrometer 5; the infrared spectrometer 5 ...

Embodiment 3

[0049] This embodiment describes the establishment of an infrared spectrum model.

[0050] The first step is to collect a variety of foods at different freshness levels, use infrared spectrometers to collect their infrared spectra, and establish a correlation model between infrared spectra and food types.

[0051] The second step is to collect infrared spectra at different temperatures, and establish a correlation model between real-time temperature and infrared spectra. When building the model, pay attention to the fact that the characteristic bands of the real-time temperature are different from those in the food category model.

[0052] The third step is to store different kinds of food at different temperatures until they deteriorate, obtain their infrared spectra at regular intervals during the storage process, and determine the temperature with the longest storage time as the suitable storage temperature, and at this temperature according to the acquired Infrared spectra...

Abstract

The invention relates to an intelligent constant-temperature fresh-keeping control device and a control method. The intelligent constant-temperature fresh-keeping control device comprises a computer and a storage cabinet; a plurality of fresh-keeping cabins are formed in each storage drawer, and the fresh-keeping cabins are provided with infrared emission heads, infrared receiving heads, air outlets and air inlets. The infrared emission heads emit infrared light into the fresh-keeping cabins, the infrared receiving heads receive the infrared light reflected by food stored in the fresh-keepingcabins and transmit the infrared light to an infrared spectrometer through optical fibers, the infrared spectrometer transmits a collected infrared spectrum to the computer, the computer inputs the infrared spectrum into a discrimination model stored in the computer, and the types of the food in the fresh-keeping cabins, the appropriate storage temperature and the maximum fresh-keeping time are judged according to the infrared spectrum; by combining with the analysis function of the infrared spectrum, the types of the food, the real-time temperature, the appropriate storage temperature and theremaining maximum fresh-keeping time are identified simultaneously; and the fresh-keeping cabins are each formed into an ellipsoid shape, circulation of an air circulating system is facilitated, thusthe temperature in the fresh-keeping cabins is uniform, fresh-keeping of the food is facilitated, all the fresh-keeping cabins are operated independently, and using is easy and convenient.

Description

technical field [0001] The invention relates to the field of smart home appliances, in particular to an intelligent constant-temperature fresh-keeping control device and control method. Background technique [0002] With the improvement of people's living standards, people pay more attention to the quality of life, health, nutrition and freshness of food. People are more aware that fresh food can bring more nutrition, and it is more beneficial to the health of the body after eating. Therefore, in order not to waste food, but also to eat fresh fruits and vegetables every day, it is necessary to ensure that the food is as fresh as possible. [0003] Application number: 201610921311.0 discloses a fruit and vegetable fresh-keeping drawer and a fresh-keeping refrigerator. The fruit and vegetable fresh-keeping drawer includes a drawer body, a nozzle assembly, a transmission part, and a nutrient solution storage box. The nutrient solution storage box and the nozzle assembly are fi...
