If the food is put in, the reading times are changed into '1', the state of the food is stored in the refrigerator, and the background processing equipment 20 adds and re-counts the food information of the food; if the food is taken out, the reading frequency of the food is changed to be "2", which indicates that the food is taken out and is going to be eaten, and the background processing equipment 20 clears the food information record corresponding to the food and counts again. Preferably, to prevent the second reading module 101b from being too sensitive, and to perform a short-time multiple scanning on the same food item, the background processing device 20 may set a minimum time interval (e.g., 0.5 seconds) acceptable for two consecutive scans of the same food item information.
Preferably, the query pattern in this embodiment provides a plurality of query services for the user to select. When a user inputs a query command through the input module 103, the query command is processed by the conversion processing module 104 and then transmitted to the background processing device 20 through the transmitting and receiving module 105;
after receiving the query command, the background processing device 20 sends a network signal including available query services to the sending and receiving module 105; available query services may include: inquiring information of food in the refrigerator, inquiring information of specified food and the like;

The process of querying the information of the food in the refrigerator is similar to that in the second embodiment, and the description of the embodiment is not repeated; the querying information of the specified food comprises the following steps:
when a user selects a command for inquiring the information of the specified food through the input module 103, the command is processed by the conversion module 104 and then is sent to the background processing device 20 through the sending and receiving module 105, and after receiving the command, the background processing device 20 waits for the user to scan one or more RFID tags of the specified food in front of the second reading module 101 b; the second reading module 101b reads the sensed food information of the specified food, and the food information is processed by the conversion module 104 and then sent to the background processing device 20 through the sending and receiving module 105; the background processing device 20 quickly retrieves the corresponding food related information for the specified food; the background processing device 20 sends the retrieved network signal containing the food-related information of the specified food to the sending and receiving module 105; the transceiver module 105 receives the network signal and transmits the network signal to the converter module 104, and the converter module 104 converts the network signal into information recognizable by the display module 102 (i.e. food-related information of the designated food), and transmits the information to the display module 102 for display.
Preferably, the background processing device 20 is a background server, and the functions and features of the background server are similar to those of the background server in the second embodiment.
Compared with the second embodiment, the method has the advantages that one or more foods specified by the user can be inquired, and the problem that the number of pages of information returned from the background processing equipment is too large due to more foods stored in the refrigerator, so that the user is inconvenient to search and time is wasted is avoided.

As shown in fig. 4, the refrigerator 10 includes: a first reading module 101a, a third reading module 101c, a display module 102, an input module 103, a conversion module 104 and a sending and receiving module 105; also used in conjunction with the refrigerator 10 is a background processing device 20. In this embodiment, the structures, the connection relationships, the functions and the operation principles of the display module 102, the input module 103, the conversion module 104 and the transmission/reception module 105 are similar to those of the second embodiment.
The present embodiment is different from the second and third embodiments in that the number of the reading modules is two, and the first reading module 101a and the third reading module 101c are connected to the conversion module 104, respectively. The first reading module 101a is disposed inside the refrigerator 10, and is configured to read food information of all food inside the refrigerator 10, and transmit the read food information to the conversion module 104; the third reading module 101c is disposed outside the refrigerator 10 (e.g., on a panel located outside a door of the refrigerator), and is configured to read food information of a food specified by a user and transmit the read food information to the conversion module 104. The first reading module 101a and the third reading module 101c may add their own identifiers to the read food information, respectively.
When the embodiment is used, if the background processing device 20 receives the food information read by the first reading module 101a, it re-counts the food information and overwrites the originally stored food information, then retrieves the food-related information for the new food information and overwrites the originally stored food-related information, which is similar to the process of the reading mode in the second embodiment; if the background processing device 20 receives the food information read by the third reading module 101c, the corresponding food-related information is retrieved for the corresponding food, and the food-related information is transmitted back to the display module 102 of the refrigerator 10 for display, which is similar to the process of querying the designated food information in the third embodiment.
Preferably, the background processing device 20 is a background server, and the functions and features of the background server are similar to those of the background server in the second embodiment.
Compared with the third embodiment, the present embodiment has the following advantages: the query of the information aiming at the specified food can be provided, meanwhile, the division of labor of each module of the refrigerator can be made clear, and the error modification of the data in the background processing device 20 and the trouble caused by the error modification due to the carelessness of the user (the food is directly close to the second reading module 101b because the user forgets to select the command of querying the information of the specified food through the input module 103) in the third embodiment are avoided.
