System For Refrigerator Goods Information Management Based On The Internet Of Things

Technology development and human environmental needs are closely linked. With the improvement of living standards, human demand increases on the living environment. Appliances, as an indispensable part of people’s lives, applying advanced technology to the home appliances is inevitable. As an important part of a new generation of IT, the Internet of Things develops rapidly. It is the trend of development of smart appliances to effectively integrate the Internet of things with home appliances.Based on the analysis of the Internet of Things technology architecture, this paper combines the research situation of item information management of the intelligent refrigerator between domestic and foreign, put forward the needs to the goods information management system of refrigerator based on the Internet of Things technology, and present a scheme of designing goods information management system of refrigerator. Specifically including:identify goods by scanning the electronic tags on the articles through the RFID (Radio Frequency Identification); get information of articles through remote information network platform and have functions of storage, management, intelligent decision-making, recommending recipes, and shopping online.Utilizing relevant technologies of the Internet of things and embedded system, based on RFID, this paper design and implements the goods information management system. These specific technologies includes radio frequency identification technology, network of Electronic Product Code, the principle of the EPC network and relevant technologies. The system hardware implements the Micro2440development board based on S3C2440processor and RFID; the software section utilizes WinCE5.0operating system. In this paper, the software development mainly involves:1. According to the serial communication protocol, appropriate program is compiled to enable the RFID reader connected and communicated with application software. By receiving and processing the data, realization of reading multiple RFID tags EPC codes and obtaining the corresponding items of information through EPC codes.2. Transplanting SQLite database into the development board, compiling the corresponding program, operating insert, update, or delete instructions to the database through the program directly; implementing the functions of storage and management of goods information and reminding the expired items.3. In order to facilitate users to understand the information of the items in the refrigerator and online shopping, the system uses MFC to develop the interactive interface. Through the interactive interface, users can inquire the information of items in the refrigerator, the number of similar items, as well as shop online. Finally, this paper analyses the feasibility and stability of all the functional modules in the system, tests them and presents the results.
