RFID-based smart refrigerator system

Abstract

The invention provides an RFID based intelligent refrigerator system in which a super-high frequency reader-writer, super-high frequency RFID tags, an operating panel, a fingerprint identifier, an Arduino development board, a miniature electronic scale, a door magnetic switch and a wireless communication module component are combined with a refrigerator. The fingerprint identifier is arranged on the outer side of the refrigerator, identifies the identity of a user and meanwhile records the time when the user uses the refrigerator, food material weights and other information. The reader-writer is arranged in the refrigerator and reads food material information attached with the RFID tags, then system reads the food material information from a background database and displays the information on the operating panel, and the user can perform interactive operation on a display screen to check the food materials stored in the refrigerator and query cookbook recommendations of the food materials and specific making methods of dishes; the user checks the expiration dates, source tracing information and the like of the food materials, takes out or puts in the food materials, the system automatically updates a food material list, records the information of the food materials taken out by the user, automatically draws a diet curve by judging the situations of edible food materials and gives out reasonable diet suggestions according to the actual health condition of the user.

Description

technical field [0001] The invention relates to the technical field of refrigerator products, in particular to an intelligent refrigerator system. Background technique [0002] With the rapid development of smart technology, smart technology has also begun to be applied to refrigerator products. Smart refrigerators have emerged, such as Haier Group's "refrigerator using radio frequency identification technology". When the door is opened, the basic information such as the production date and shelf life of the food in the refrigerator can be obtained. However, at present, smart refrigerator systems including the above-mentioned smart refrigerator technology disclosed by Haier generally suffer from high cost, inability to identify user identities, time-consuming viewing of ingredients information, inability to record user diet, inability to provide reasonable advice on user diet, inability to There are defects such as providing traceability information of ingredients, and the ...
