【摘要】 科技的发展与人们对环境的需求紧密相连,随着生活水平的提高,人们对生活环境的要求也越来越高。家电作为人们生活中不可缺少的一部分,将先进技术渗透到家电是发展的必然。物联网作为新一代信息技术的重要组成部分,得到快速发展,其与家电的有效结合是未来智能家电的发展趋势。本文在分析了物联网的技术架构的基础上,结合国内外对智能冰箱物品信息管理的研究现状,提出了基于物联网技术的冰箱物品信息管理系统的功能需求,并给出了冰箱物品信息管理系统的设计方案,具体包括：使用RFID (Radio Frequency IDentification,射频识别)读写器扫描贴在物品上的电子标签,实现对物品的识别,并通过网络远程获取物品的相关信息；具有物品信息存储和管理、智能决策、推荐食谱、在线购物等功能。采用物联网相关技术以及嵌入式系统设计和实现了基于RFID的冰箱物品信息管理系统。其中包括射频识别技术、电子产品编码(Electronic Product Code,EPC)网络的概念、EPC网络的工作原理及相关技术；系统采用基于嵌入式微处理器S3C2440的Micro2440开发板和RFID作为硬件平台,软件部分使用WinCE5.0操作系统。本文进行的软件开发主要包含以下部分：1.根据串口通信协议,编写相应的程序,使RFID读写器与应用软件进行通讯连接。对接收的数据进行相关处理,实现读取多个电子标签的EPC码,并通过EPC码获取对应物品的信息。2.采取了在开发板上移植SQLite嵌入式数据库,并编写了相应的程序,通过程序直接对数据库进行插入、更新、删除等操作,实现对物品信息的存储和管理,以及物品过期提示功能。3.为了方便用户了解冰箱中的物品信息以及在线购物,系统采用MFC开发了人机交互界面。通过人机交互界面,用户可以查询冰箱中的物品信息、同类物品的数量,以及进行在线购物。本文最后对系统的各功能模块的可行性和稳定性进行了测试与结果分析。更多还原

【Abstract】 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.更多还原
