Problems solved by technology

Moreover, for what food is placed in the refrigerator, the type and quantity of the food, and the flow rate, the user will not know without opening the refrigerator.
This has led many families to blindly buy too much food, or cause the food in the refrigerator to expire and be wasted, or the food in the refrigerator to expire without knowing it

Embodiment 1

[0020] This embodiment provides a smart refrigerator with RFID tag function, which includes:

[0021] Refrigerator cavity, refrigeration system, main control system and RFID power amplifier module;

[0022] The RFID power amplifier module is used to collect the RFID information of the food in the refrigerator, the refrigeration system and the RFID power amplifier module are both connected to the main control system, and the main control system is connected to the user terminal and / or the food supplier through Communication network and / or Internet wireless signal connection.

[0023] The RFID power amplifier module is used to actively transmit signals for reading and writing, while the RFID tag is used to store information, readable and writable, which is equivalent to a readable and writable memory chip; multiple partitions in the refrigerator cavity The RFID tags are respectively set in the refrigerator cavity, which are respectively used to read or receive and write the RFI...

Embodiment 2

[0031] This embodiment provides a working method of the smart refrigerator with the RFID tag function described in Embodiment 1, including the following steps:

[0032] When the refrigerator door is opened, the RFID power amplifier module is started, and each RFID tag is read or accepted to write the RFID information of the food in its corresponding area, and the RFID power amplifier is turned off after the reading or writing is completed module;

[0033] When the refrigerator door is closed, the RFID power amplifier module is started, and the RFID information of the food in the corresponding area of ​​each RFID tag is read again, and the RFID power amplifier module is closed after the reading is completed;

[0034] Perform a comparative analysis of the RFID information read or written to the plurality of RFID tags twice, and the RFID tag information read twice and the comparative analysis results, or, the comparative analysis results, transmitted to the master control system...

Embodiment 3

[0038] This embodiment provides another working method for a smart refrigerator with an RFID tag function, which differs from the method described in Embodiment 2 in that:

[0039] Compare the results of comparative analysis of the RFID information read or written twice by the plurality of RFID tags with the working status information of the refrigeration system and the data in the pre-stored refrigerator processing information table, and then according to the The corresponding processing mode in the processing information table selects whether to issue a purchasing instruction to the food supplier, and / or whether to issue a refrigeration adjustment instruction to the refrigeration system.

Abstract

The invention provides an intelligent refrigerator with an RFID function. The intelligent refrigerator comprises a refrigerator cavity, a refrigerating system, a main control system and an RFID power amplification module. The RFID power amplification module is used for collecting RFID information of food in the refrigerator, the refrigerating system and the RFID power amplification module are both connected with the main control system through signals, and the main control system is connected with a user terminal and / or a food supplier through a communication network and / or Internet wireless signals. According to the intelligent refrigerator with the RFID tag function, the RFID power amplification module is additionally arranged on a traditional refrigerator, the refrigerator can intelligently know the current state and the change of the food in the refrigerator, a user can remotely monitor the state of the food in the refrigerator and make a decision to dispose or adjust the food in the refrigerator, and the intelligent refrigerator is suitable for the current living state and tendency of people for the fast rhythm, material abundance and intelligent control, is a large constituent part of intelligent home and is a great progress.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an intelligent refrigerator with an RFID tag function. Background technique [0002] With the development of the economy and the improvement of people's living standards, refrigerators are no longer a luxury item, but have approached thousands of households in urban and rural areas and become a necessity for every family. [0003] On the other hand, in recent years, with the popularization of computers and the Internet, the Internet of Things technology and cloud computing technology have developed rapidly and changed with each passing day, and have been increasingly used in various fields. [0004] Traditional refrigerators have two functions of refrigeration and freezing. However, since the refrigerator came out, these two functions have not changed fundamentally. It is necessary for the user to purchase the product and put it in the corresponding space of the ref...
