Specifically, the food material decay information library may be an information library pre-stored in the server by the food material monitoring system in the refrigerator before the food material monitoring system executes the embodiment. It should be noted that the food material monitoring system in the refrigerator may comprehensively analyze the obtained first food material color values, so as to determine an stale first sub-food material in the first food material. Optionally, the freshness of the food material and the rotten degree of the food material may be inversely proportional; the higher the freshness of the food material, the lower the degree of rotting, and the lower the freshness of the food material, the higher the degree of rotting.
And step S4000, removing volatile rotten gas in the first gas according to the first sub-food material to obtain second gas.
Specifically, the food material monitoring system in the refrigerator can obtain processing information according to the stale first sub-food material, so as to eliminate volatile rotting gas in the first gas according to the processing information, that is, update the first gas in the common cold storage area, and obtain the second gas. Optionally, the processing information may be related information of the first sub-food material.

Optionally, as long as the intelligent refrigerator is powered on and works normally, the food material monitoring system in the refrigerator can execute a circulation work flow to the common cold storage area, and the process from the step S1000 to the step S4000 is continuously circulated.
The method for supervising the food materials in the refrigerator comprises the following steps: acquiring the content of mixed volatile gas in first gas in a common cold storage area, acquiring a first food material image corresponding to first food material in the common cold storage area when the content of the mixed volatile gas is greater than a volatile gas content threshold value, acquiring a first food material color value of the first food material image, analyzing and processing the first food material color value and a food material decay information base, determining a first stale sub-food material in the first food material, removing volatile decay gas in the first gas according to the first sub-food material to obtain second gas, taking the second gas as the first gas, and continuously acquiring the content of the mixed volatile gas in the first gas in the common cold storage area; the method can monitor gas in a common refrigerating area in the intelligent refrigerator in real time to obtain the content of mixed volatile gas, determine stale food materials in the common refrigerating area according to the content of the mixed volatile gas, and further remove volatile rotten gas in the common refrigerating area according to the stale food materials; meanwhile, the method can process the volatile rotten gas in the intelligent refrigerator in real time according to the real-time monitoring result, so that the freshness timeliness of the gas in the intelligent refrigerator is improved, the freshness of food materials stored in the intelligent refrigerator is kept to a great extent, and the harm to the health of people is reduced as much as possible.
As an example, the step of obtaining the content of the mixed volatile gas in the first gas in the common cold storage area in step S1000 may be implemented by the following steps:
step S1100, detecting and analyzing the first gas to obtain the content of the first component contained in the first gas.
Specifically, the built-in peculiar smell sensor in the common cold storage area in the refrigerator can detect and analyze the first gas, obtain different first component contents contained in the first gas, and simultaneously can send the different first component contents to the server for processing. Optionally, the first gas is a mixed gas containing different gas components, and the content of each gas component may be the same or different. Alternatively, the gas component may be a rotten gas component and/or a normal gas component volatilized from the food material. Optionally, the rotting gas components that can be volatilized after the food material is not fresh and deteriorated are shown in fig. 5 as a list of information about main rotting gas components that are volatilized after a certain food material is not fresh and deteriorated.
And step S1200, performing operation processing according to the content of the first component to obtain the content of the mixed volatile gas.
Specifically, a server in the food material monitoring system in the refrigerator can perform operation processing on different first component contents to obtain the content of the mixed volatile gas. Alternatively, the arithmetic processing may be addition, subtraction, multiplication, division, or combination arithmetic processing, logical arithmetic processing, or the like.
The step S1200 of obtaining the content of the mixed volatile gas by performing operation processing on the content of the first component may specifically include: and performing weighted summation operation on each different first component content to obtain the content of the mixed volatile gas.
In the present embodiment, the above operation processing may be fitting operation processing of a plurality of variables, that is, weighted sum operation processing. For example, the different first component contents in the first gas are each X1、X2、…、Xi、…、Xn(n represents the amount of the gas component volatilized from the first gas), the mixed volatile gas content Y corresponding to the first gas may be equal to a1X1+a2X2+…+aiXi+…+anXn(i represents the weighting factor corresponding to the first component content). Optionally, the decay rates of the food materials may be different; the weighting factor corresponding to the content of the first component of the non-perishable material may be less than the weighting factor corresponding to the content of the first component of the perishable material.
The method for supervising the food materials in the refrigerator can acquire the content of mixed volatile gas in first gas in a common cold storage area, further determine stale first sub-food materials in the first food materials according to the content of the mixed volatile gas, eliminate volatile rotten gas in the first gas according to the first sub-food materials to obtain second gas, use the second gas as the first gas, and continue to acquire the content of the mixed volatile gas in the first gas in the common cold storage area; the method can be used for monitoring the gas in the common cold storage area in the intelligent refrigerator in real time, and then processing the volatile rotten gas in the intelligent refrigerator in real time according to the real-time monitoring result, so that the timeliness of freshness of the gas in the intelligent refrigerator is improved, the freshness of food materials stored in the intelligent refrigerator is kept to a great extent, and the harm to the health of people is reduced as much as possible.
As an example, the process of acquiring the first food material color value of the first food material image in the step S2000 can be implemented by the following steps:
step S2100, performing color recognition processing on the first food material image to obtain the first food material color value.
Specifically, a server in the food material supervision system in the refrigerator may perform color recognition processing on the first food material image by using a color recognition algorithm to obtain a first food material color value. Optionally, the different colors all have corresponding color values.
Further, the process of analyzing and processing the first food material color value and the food material decay information base in the step S3000 to determine the stale first sub-food material in the first food material may specifically include: and matching the first food material color value with the food material color values in the food material rotting information base, and determining the first sub-food material according to a first matching result.
Specifically, the information stored in the food material decay information library may include food material color values corresponding to different colors exhibited by the appearances of various food materials and the freshness of the food materials. Optionally, the matching may be characterized as a process of matching the data and/or information. Optionally, each food material color value has a corresponding freshness, that is, the food material color values and the freshness are in a one-to-one correspondence relationship. Alternatively, the matching process may be understood as a search process. Optionally, the server may search for the food material color value identical to the first food material color value in the food material decay information base, obtain a first matching result after the search, and determine an stale food material in the first food material according to the first matching result. Optionally, the first matching result may include a food material color value and a freshness of the food material.
The method for supervising the food materials in the refrigerator can acquire a first food material color value of a first food material image, further analyze and process the first food material color value and the food material rotting information base, determine a first sub-food material which is not fresh in the first food material, eliminate volatile rotting gas in first gas according to the first sub-food material to obtain second gas, use the second gas as the first gas, and continue to acquire the content of mixed volatile gas in the first gas in a common cold storage area; the method can be used for monitoring the gas in the common cold storage area in the intelligent refrigerator in real time, and then processing the volatile rotten gas in the intelligent refrigerator in real time according to the real-time monitoring result, so that the timeliness of freshness of the gas in the intelligent refrigerator is improved, the freshness of food materials stored in the intelligent refrigerator is kept to a great extent, and the harm to the health of people is reduced as much as possible.
As an example, the step S4000 of obtaining the second gas by removing the volatile putrid gas in the first gas according to the first sub-food material may be implemented by:
step S4100, outputting first prompt information according to the first sub-food material.
Specifically, when the server in the food material monitoring system in the refrigerator determines that an stale first sub-food material exists in the first food material, the server may send a prompt instruction to the intelligent refrigerator, and the intelligent refrigerator responds to the prompt instruction and outputs first prompt information. Optionally, the first prompt message may be related information that the first sub-food material is not fresh and needs to be processed in time. Optionally, the first prompt information may be in a voice broadcast mode and an information display mode, and the information display mode may be a text information display mode. Optionally, the first prompt message may be an indicator light display status and a text display message. Optionally, the text display information may be displayed by a full house information display device.
And step S4200, according to the first prompt message, removing volatile rotting gas in the first gas to obtain the second gas.

Optionally, the refrigerator may obtain the instruction of removing the volatile rot gas only when the first prompt information is related to stale food materials.
The method for supervising the food materials in the refrigerator can analyze and process the color value of the first food material and the food material rotting information base, determine a first stale sub-food material in the first food material, remove volatile rotting gas in first gas according to the first sub-food material to obtain second gas, and continue to obtain the content of mixed volatile gas in the first gas in a common cold storage area by taking the second gas as the first gas; the method can be used for monitoring the gas in the common cold storage area in the intelligent refrigerator in real time, and then processing the volatile rotten gas in the intelligent refrigerator in real time according to the real-time monitoring result, so that the timeliness of freshness of the gas in the intelligent refrigerator is improved, the freshness of food materials stored in the intelligent refrigerator is kept to a great extent, and the harm to the health of people is reduced as much as possible.
Fig. 6 is a flowchart illustrating a method for supervising food materials in a refrigerator according to another embodiment. The method may further comprise the steps of:
and S6000, collecting a second food material image corresponding to a second food material in each special area in the special refrigerating area, and acquiring a second food material color value of the second food material image.
Specifically, the processing procedure of step S6000 is similar to that of step S2000, except for the processing object. Step S6000 is to process the second food material in each special area in the cold storage special area in the refrigerator. Optionally, the special refrigerating area may comprise a plurality of special areas, and each special area can only store one type of food materials. The food material monitoring system in the refrigerator can independently process each special area and is not related to each other.
Step S6100, detecting and analyzing the third gas in each specific region to obtain a second component content contained in the third gas.
It should be noted that, an odor sensor arranged in each special area in the special refrigerating area in the refrigerator can detect and analyze the third gas in the special area to obtain different second component contents contained in the third gas, and at the same time, the odor sensor can transmit the second component contents which are not provided to the server for processing. Alternatively, the third gas may be a mixed gas containing different gas components, and the content of each gas component may be the same or different. Alternatively, the gas component may be a rotten gas component and/or a normal gas component volatilized from the food material.
Step 6200, comparing the second ingredient content with an ingredient content threshold value, according to a comparison result, performing operation processing on the second food material color value and the second ingredient content, and determining an stale second sub-food material in the second food material.
Specifically, the server in the food material monitoring system in the refrigerator may compare the second component content with a corresponding component content threshold, and determine to perform operation processing on the second food material color value and the second component content according to a comparison result, so as to obtain a second stale sub-food material in the second food material. Optionally, each special area in the special refrigerating area can store different food materials, and the gas component volatilized from each food material can also be different, so that the content of the second component generated by each special area can also be different. Optionally, the component content threshold corresponding to each specific region may be different; the component content threshold value can represent the critical value of the content of volatile gas generated when the food materials stored in the special area are fresh and not fresh respectively.
