Design And Realization Of Intelligent Refrigerator Food Management System

With the rapid development of the people’s living standards and the accelerating pace of life, fridges play a great role in families, which are handy for modern life. However, more and more food in it, on the one hand, it is likely to expire and cause unnecessary waste if you are not eating these foods in a timely manner; on the other hand, people can’t figure out what foods easily exhausted, and cannot be purchased in a timely manner to add.This paper uses the Intel PXA270 embedded microprocessor built hardware platform, the embedded Linux operating system to QT 4.7 as a development tool, using a radio frequency identification(RFID), a wired network access, network security, SQLite database technology to develop a sets have online shopping features to smart refrigerator freezer intelligent management system of various types of food. The system can be docked with the current mainstream shopping site, to achieve intelligent Internet refrigerator to buy food, to win a bigger market. RFID tracking and management of food dependent on technology, reader and tag communication protocol to take a half duplex mode, the reader is in a dominant position, that the reader first say, labels are not on their own initiative to send data to the reader. Using an effective anti-collision method to solve multiple tags simultaneously into the reader’s range of problems arising from the conflict, and on the basis of the use of the anti-collision method, to reduce circuit complexity, reduce the demand for memory, in order to achieve low power consumption and low cost optimization.Application of intelligent systems for the urban population refrigerator busy life to provide convenient, solve many trivial things of life, so that people can be more focused on their work, their studies; same time, can also be derived for other commercial applications such as RFID-based smart supermarket, very big things in promoting development. Smart fridge freezer system for the entire food directional tracking, frozen food information readily available, can use the computer to find suitable raw recipes on hand, you can also view the phone on how much food in the refrigerator, to meet future smart home needs. After using radio frequency technology and information processing technology, RFID refrigerator can play the advantages of RFID technology, to provide protection for the health of modern family life, reducing the waste of social resources, in line with the concept of green contemporary society, can be applied to the smart home.
