[Abstract]:The development of science and technology is closely related to people's demand for environment. With the improvement of living standard, people's demand for living environment is higher and higher. As an indispensable part of people's life, it is inevitable to infiltrate advanced technology into household appliances. As an important part of the new generation of information technology, the Internet of things has been developed rapidly, and its effective combination with home appliances is the development trend of intelligent home appliances in the future. Based on the analysis of the technical framework of the Internet of things and the current situation of the research on the information management of intelligent refrigerators at home and abroad, this paper puts forward the functional requirements of the information management system of the refrigerator articles based on the technology of the Internet of things. The design scheme of refrigerator item information management system is given, which includes: using RFID (Radio Frequency IDentification, radio frequency identification) reader to scan the electronic label affixed to the object, so as to realize the recognition of the object. It has the functions of storing and managing items information, intelligent decision making, recommending recipes, shopping online and so on. A refrigerator item information management system based on RFID is designed and implemented by using Internet of things (IoT) technology and embedded system. It includes radio frequency identification technology, the concept of electronic product coded (Electronic Product Code,EPC) network, the working principle of EPC network and related technology. The system adopts Micro2440 development board based on embedded microprocessor S3C2440 and RFID as hardware platform. The software part uses WinCE5.0 operating system. The software development in this paper mainly includes the following parts: 1. According to the serial communication protocol, write the corresponding program so that the RFID reader and application software communication connection. The EPC code of multiple electronic tags can be read by processing the received data, and the information of corresponding items can be obtained by EPC code. 2. The SQLite embedded database is transplanted on the development board, and the corresponding program is written, through which the database can be inserted, updated and deleted directly, so as to realize the storage and management of the item information. And item expiration prompt function. 3. In order to facilitate the users to understand the information of items in the refrigerator and online shopping, the system uses MFC to develop the man-machine interface. Through the man-machine interface, the user can query the information of the items in the refrigerator, the quantity of the similar items, as well as the online shopping. Finally, the feasibility and stability of each functional module of the system are tested and analyzed.
