RFID based intelligent 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.

AI Technical Summary

Benefits of technology

This technology allows users to access their meal menu from remote servers without having them leave or visiting restaurants. Users only have one device that they use while sitting inside their own fridge cabinet. They also provide various features like cooked rice pads, coffee cups, tea bags, oven mittles, barbecue grills, and other items such as ice cream chips used during dinner parties. These devices are connected to databases called SQLite (a type of relational database) where tables hold important attributes about how well it'll be working properly. Overall this system helps improve nutritional values and make life easier for individuals who don't want to take care of themselves outside.

Problems solved by technology

The technical problem addressed in this patented text relates to current smart receptacles that require expensive equipment for data acquisition or recording purposes due to their low accuracy during opening doors. This makes it difficult for people who want access to certain items stored within them without being able to see what they were doing right now.
