The invention relates to a refrigerator and a control method thereof. The refrigerator comprises a refrigerator body; a refrigerator door; and multiple antennas; and a controller is configured to control each antenna to perform frequency sweeping detection for each antenna when determining that a tag inventory starting condition is satisfied, so as to determine an optimal identification frequency point, corresponding to the antenna, of each electronic tag in the refrigerator body from a working frequency interval of each antenna, wherein the optimal identification frequency point is a working frequency point of each antenna when the received signal strength of the corresponding electronic tag is maximum; for each antenna, the antenna is controlled to identify each electronic tag in sequence according to the optimal identification frequency point of each electronic tag corresponding to the antenna so as to obtain a tag information set collected by the antenna, wherein the tag information set comprises tag information of each electronic tag; and food material management is performed according to the tag information set collected by all the antennas. According to the refrigerator and the control method thereof, the tag identification rate is high, and the food material management accuracy can be improved.
Description
technical field [0001] The invention relates to the technical field of refrigerators, in particular to a refrigerator and a control method for the refrigerator. Background technique [0002] With the development of science and technology, there are already many refrigerators at present, by arranging RFID antennas in the refrigerator's cold room, wide room, and freezer room, and by reading the food information stored in different electronic tags, the identification and management of the food in the refrigerator can be realized. . At present, most readers use a random frequency hopping pattern within the specified frequency band to identify tags. [0003] However, the inventors found in the process of implementing the present invention that due to factors such as the metal structure inside the refrigerator and the moisture content of the food itself that would interfere with the transmission of the RFID signal, there were certain blind spots in the existing label identificati...
