Food management method and food management system of smart refrigerator

Abstract

The invention discloses a food management method and food management system for an intelligent refrigerator. The food management method comprises the steps that identification information of a mobile RFID tag is recognized; the action type of the mobile RFID tag is judged according to the change tendency of the signal intensity of the mobile RFID tag; and the identification information and the action type are matched, so that a food storage datum is formed. Compared with the prior art, the food management method and food management system for the intelligent refrigerator have the beneficial effects that the action type of the mobile RFID tag is judged through the change tendency of the signal intensity so that the storage and taking states of food in the refrigerator can be monitored in real time; and by monitoring the storage and taking states of food, monitoring of partial taking-out or supplement of food of the same type can be achieved, and the intermediate process of food taking and placing by a user can also be obtained to achieve intelligent monitoring of food under the condition that RFID tags are identical when a refrigerator door is opened and closed.

Description

technical field [0001] The invention relates to a food management method and a food management system of an intelligent refrigerator, belonging to the technical field of intelligent refrigerators. Background technique [0002] With the continuous development of society, smart home has increasingly become an inevitable development trend of family life. As an indispensable household appliance for family life, the refrigerator itself is also imperative to be intelligent. With the research of radio frequency identification (Radio Frequency Identification, referred to as RFID) technology, RFID technology is gradually applied to the technical field of smart refrigerators. [0003] RFID technology is a communication technology that can identify specific targets and read and write related data through radio signals without establishing mechanical or optical contact between the identification system and specific targets. Its most important advantage is non-contact identification, wh...

AI Technical Summary

Problems solved by technology

It is impossible to truly track and identify the entry and exit of food, and it is impossible to judge the type of food and the corresponding quantity / weight each time a user takes food; the lack of real intelligent management of food affects the refrigerator's ability to make food based on the user's eating habits To the effect of intelligent reminder

If the problem of not being able to judge food in and out and track the amount of food in and out is not resolved, it will not be conducive to the development of intelligent and humanized refrigerators
