Food management method and food management system of intelligent refrigerator

Abstract

The invention discloses a food management method and a food management system of an intelligent refrigerator. The food management method includes the steps of recognizing the identification information of a mobile RFID label and synchronously detecting the weight of the refrigerator; obtaining the weight information of food corresponding to the mobile RFID label according to the change of the weight; judging the movement type of the mobile RFID label; matching the identification information, the weight information and the movement type to generate a food storage datum. Compared with the prior art, the weight change and storage and taking state of the specific food are tracked in real time through detection on the mobile RFID label in combination with collection of the weight information by a weighting sensing module. Not only can intelligent management be realized, but also weight monitoring on the taken-out part or added part of the same food is realized, for example, the condition of taking out part of bread from the refrigerator or the condition of taking out a rice box to add rice, and the taken-out amount, added weight and residual weight of the bread or rice can be intelligent judged.

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 the user takes food. For example, when the refrigerator is opened, the meat stored in the refrigerator is taken out and cut. Partly, when putting it into the refrigerator, the existing technology cannot intelligently judge how much meat is taken out or how much meat is left, which is insufficient in intelligence; and the lack of real intelligent management of food affects the eating habits of the refrigerator for users Achieve 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
