Specifically, in S1, the food in the refrigerating chamber is contained in respective food bags, and the food bags are transparent preservation bags; as shown in fig. 2, the step of the refrigerator detecting the freshness of the stored food includes:

s011, a camera in a refrigerating chamber of the refrigerator collects images of food in the food bag and sends the images to a processor, and the processor compares image information collected by the camera with color saturation of corresponding fresh food stored in a remote server and calculates a color saturation difference value.

And S012, acquiring odor concentration data of the food by an odor sensor in a refrigerating chamber of the refrigerator.

The odor concentration data is specifically a detectable resistance value which is converted out by the odor sensor according to the odor intensity. The smell sensor can convert the detected smell intensity into a detectable resistance value, and in the application, the larger the detected smell intensity is, the larger the converted resistance value is.

S013, odor concentration data of the unit food bags are calculated according to the number of the food bags.

Specifically, for different kinds of food, the weight values of the odor concentration data and the color saturation difference value of the unit food bag of the food in the aspect of determining the freshness of the food are preset. The comparison table of the corresponding freshness when the odor concentration data of the unit food bag and the color saturation difference value change under a single variable (namely, when only the odor concentration data or the color saturation difference value change of the unit food bag is considered) can be respectively set for each kind of food, the sum of the two freshness values multiplied by the corresponding weight values is calculated, and the sum is determined as the unfrozen freshness of the food, wherein the sum of the weight values of the odor concentration data and the color saturation difference value of the unit food bag in the aspect of determining the freshness of the food is 1. Specifically, the freshness value in the comparison table corresponding to freshness under the condition that the odor concentration data and the color saturation difference value of the unit food bag under the single variable are changed can be determined as follows: taking the color saturation of the food with standard freshness as a reference value, and defining the freshness value as 1 (namely freshness) when the change of the color saturation difference value is not more than 10% compared with the reference value; when the change of the color saturation difference value exceeds 10% but is less than 20% of the reference value, the freshness value is defined as 0.8, and the like, and the freshness is a decimal between 1 and 0, i.e. the larger the change of the color saturation difference value is compared with the reference value, the smaller the corresponding freshness value is, the fresher the color saturation difference value is, and the fresher the color is. Similarly, the odor concentration of a unit food bag of food with standard freshness can be used as a reference value, and the corresponding freshness value can be determined according to the proportion of the detected odor concentration value of the food in unit volume exceeding, wherein the freshness is a decimal between 1 and 0.

Specifically, as shown in fig. 3, the S2 includes:

and S21, acquiring food allowance information of food in the refrigerator.

Specifically, the food remaining amount information includes a food type and a food quantity, wherein the food quantity may be a food bag quantity. Because the invention is applied to the refrigerator which is taken and placed by a user, in order to manage the food quantity, the food quantity is usually measured by adopting the concept of 'shares', and each 'share' of food is contained in a corresponding food bag. The unit of a "serving" of food in the food bag may be predetermined. Different foods correspond to different eating modes, and some foods, such as soybeans, cauliflower, red beans, millet and the like, are generally taken according to the weight of food materials when being eaten, and some foods, such as pears, cucumbers and the like, are generally taken according to the number of the food materials when being eaten. For example, when a user cooks red beans, the red beans are generally taken in units of grams, and when the user eats apples, the red beans are generally taken in units of individual units. Therefore, the terminal can adopt different metering modes when determining the residual amount of the food materials. For example, if apples are contained in a food bag, one food bag dictates that 2 apples must be contained; if the food bags contain rice, one food bag is specified to contain 1kg of rice; by adopting the way of measuring by parts, the remaining amount information of different foods can be obtained only by obtaining various food types and the number of the food bags corresponding to the food types in the current refrigerator.

And S22, acquiring the food consumption rate of the different kinds of food in the current time period according to the recorded historical fetching information.

When a user pays for taking out corresponding food from the refrigerator, the refrigerator sends information of the type, the taking-out amount and the taking-out time of the corresponding food to the remote server, so that historical fetching records in a corresponding time period (such as 18: 00-20: 00 in the afternoon) in a long-term time range (such as in the last month) are stored in the remote server, the data are summarized, and the consumption rates of different types of food in the corresponding time period in the near term are calculated. For example, the method is used for the treatment of the early-month afternoon load of 18: 00-20: 00, the food consumption rates of different types in the range of 18: 00-20: the consumption rate of tomatoes was 2 parts per 10 minutes, the consumption rate of beans was 3 parts per 10 minutes, etc. over a 00 time period. It is worth mentioning that the food consumption rates of different types of food in the current time period obtained through the recorded historical fetching information are objectively real rules reflected according to the existing real information, and the objective rules can reflect the truest user preference to a certain extent, and background workers do not need to depend on seasonal changes, regional diet differences and the like excessively to meet the user preference.

S23, the refrigerator judges whether food with too low food consumption rate exists, if yes, the food is deleted from a preset food request list, an alternative food list is sent to the user for the user to vote and select favorite food, and then S24 is executed; if not, go directly to S24.

Specifically, different voting weight values are set for different users according to the distance between the user and the refrigerator and the comprehensive consideration such as the fetching frequency and the accumulated consumption amount of the user, then the voting weight values are integrated, the ranking of the food selected by the user is counted, and the food type to be supplemented is determined according to the ranking sequence of the food.

Specifically, as shown in fig. 4, the S4 includes:

and S41, sending the geographic position information of the refrigerator and the corresponding food to be taken out information to a remote server by the refrigerator.

The food to be taken out is the information of the type and the quantity of the food with the food consumption rate meeting the requirement in the current refrigerator.

The food demand terminal can be a mobile phone held by a food demand user, and the mobile phone is loaded with an application program APP capable of sending mobile phone position information to the remote server. By adopting the mode, the information of the food demand users around the refrigerator initiating the food request can be matched as much as possible, so that the users can quickly arrive at the position of the refrigerator as much as possible to obtain food.

Specifically, as shown in fig. 5, the S5 includes:

and S51, the refrigerator obtains the change trend of the food quality under the storage condition according to the acquired information of the stored food.

By utilizing a big data technology and a cloud computing technology, the quality change trend (characteristics) of the food can be obtained under the condition of known food types and storage environments. One embodiment is that the quality change trend of the food is obtained from a remote server according to the food category and the storage condition; another embodiment is to store the trend of the quality change of various foods under different storage conditions in the local application program in advance for standby. The food quality variation trend can be a 'food quality-preservation time' image, so that the remaining time length of the current food when reaching a preset quality threshold value is estimated.

Specifically, as shown in fig. 6, the S6 includes:

s61, the remote server sends the single sale price information of the corresponding food to the user terminal, and sends the fetching code to the user after the user pays.

S62, the refrigerator receives the fetching code input by the user, provides corresponding food for the user according to the fetching code information, and sends the fetching time of the user to the remote server.

Further, if the credit rating of the user is reduced to the predetermined credit rating, more robust measures are taken, such as not providing the user with the fetching service within a certain time range (e.g., three days), and the like.

Specifically, as shown in fig. 7, the S7 includes:

and S71, the refrigerator sends the replenishment information to the remote server, and the remote server sends the replenishment information to the supplier client.

And S72, the refrigerator acquires the images of the food put into the food bag in the refrigerator by the supplier.
