Refrigerator and food material positioning method thereof

Abstract

The invention discloses a refrigerator. The refrigerator is characterized by comprising a refrigerator body, a reader-writer and a controller, wherein the reader-writer is arranged in the refrigerator body and comprises a reader-writer host and a plurality of antennas; the controller is configured to obtain model updating parameters sent by a server side, update a positioning model pre-stored in the refrigerator according to the model updating parameters, obtain the accuracy rate of the updated positioning model after the updated positioning model is used for a preset time period, reserve the updated positioning model when the accuracy rate is greater than a preset accuracy rate threshold value, input the signal intensity of an RFID tag corresponding to the same food material information received by the reader-writer host into the updated positioning model when a preset positioning condition is satisfied, obtain positioning information output by the model as positioning information of the current food material, and display the positioning information on a display. The invention further discloses a food material positioning method of the refrigerator. By adopting the refrigerator and the food material positioning method thereof disclosed by the embodiment of the invention, the food material positioning accuracy can be improved, so that a user can quickly know the storage position of the food material.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a refrigerator and a method for locating ingredients thereof. Background technique [0002] Smart home is the inevitable result of the infiltration and development of IT technology, network technology and control technology into the traditional home appliance industry. As a representative of smart home, smart refrigerator has become a breakthrough product that major companies are competing to develop. Smart refrigerators are based on food storage, bringing users a more humane sense of use. As refrigerators become more and more intelligent, more and more refrigerators choose to use radio frequency identification (RFID) technology to identify the food in the refrigerator, and put RFID (Radio Frequency Identification, radio frequency identification) tags on the ingredients in the refrigerator. The data received by each tag is collected by the reader, and then the data is pro...

AI Technical Summary

Problems solved by technology

However, the existing technology for identifying food storage locations based on RFID tags can only identify which storage room the food is stored in, and cannot further identify the distribution location of the food in the storage room. When the storage space of the storage room is large, even Inform the user which storage room the food is stored in, and it is still impossible to quickly find this ingredient
