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.
